The efficiencies were compared with the solar panels without any efficiency improvement technique. The efficiency of each setup was computed on an hourly basis every day for a month. The study compared the efficiencies and combined systems that significantly improved at a specific time of the day. The data showed that the solar tracking system had the highest efficiency during 6:00 AM to 7:45 AM. Then after 7:45 AM, the combination of both solar tracking and water-spray cooling system was the most efficient to use up to 12:00 NN. Meanwhile, from 12:00 NN to 12:45 PM, the water-spray cooling system had the significant contribution on efficiency. From 12:45 PM up to 4:30 PM, the combination of both systems was the most efficient, and lastly, from 4:30 PM to 6:00 PM, the solar tracking system was the best to use. The study intended to use solar tracking or water-spray cooling system or combined systems alternately to improve the solar panel efficiency on a specific time of the day. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20panel%20efficiency" title="solar panel efficiency">solar panel efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panel%20efficiency%20technique" title=" solar panel efficiency technique"> solar panel efficiency technique</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20tracking%20system" title=" solar tracking system"> solar tracking system</a>, <a href="https://publications.waset.org/abstracts/search?q=water-spray%20cooling%20system" title=" water-spray cooling system"> water-spray cooling system</a> </p> <a href="https://publications.waset.org/abstracts/122446/characterization-of-solar-panel-efficiency-using-sun-tracking-device-and-cooling-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2334</span> Control Strategy of Solar Thermal Cooling System under the Indonesia Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budihardjo%20Sarwo%20Sastrosudiro">Budihardjo Sarwo Sastrosudiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Arnas%20Lubis"> Arnas Lubis</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Idrus%20Alhamid"> Muhammad Idrus Alhamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasruddin%20Jusuf"> Nasruddin Jusuf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solar thermal cooling system was installed on Mechanical Research Center (MRC) Building that is located in Universitas Indonesia, Depok, Indonesia. It is the first cooling system in Indonesia that utilizes solar energy as energy input combined with natural gas; therefore, the control system must be appropriated with the climates. In order to stabilize the cooling capacity and also to maximize the use of solar energy, the system applies some controllers. Constant flow rate and on/off controller are applied for the hot water, chilled water and cooling water pumps. The hot water circulated by pump when the solar radiation is over than 400W/m<sup>2</sup>, and the chilled water is continually circulated by pump and its temperature is kept constant 7 °C by absorption chiller. The cooling water is also continually circulated until the outlet temperature of cooling tower below than 27 <sup>o</sup>C. Furthermore, the three-way valve is used to control the hot water for generate vapor on absorption chiller. The system performance using that control system is shown in this study results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption%20chiller" title="absorption chiller">absorption chiller</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20system" title=" control system"> control system</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cooling" title=" solar cooling"> solar cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/43453/control-strategy-of-solar-thermal-cooling-system-under-the-indonesia-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43453.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2333</span> CFD Analysis of Passive Cooling Building by Using Solar Chimney for Mild or Warm Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naci%20Kalkan">Naci Kalkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ihsan%20Dagtekin"> Ihsan Dagtekin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents the design and analysis of solar air-conditioning systems particularly solar chimney which is a passive strategy for natural ventilation, and demonstrates the structures of these systems’ using Computational Fluid Dynamic (CFD) and finally compares the results with several examples, which have been studied experimentally and carried out previously.

In this work, a simulation analysis using TRNSYS software has been carried out to study the benefit of employing a solar adsorption cooling system under the climatic conditions of Al-Minya city, Egypt. A theoretical model was carried out on a two bed adsorption cooling system employing granular activated carbon-HFC-404A as working pair. Temporal and averaged history of solar collector, adsorbent beds, evaporator and condenser has been shown. System performance in terms of daily average cooling capacity and average coefficient of performance around the year has been investigated. The results showed that maximum yearly average coefficient of performance (COP) and cooling capacity are about 0.26 and 8 kW respectively. The maximum value of the both average cooling capacity and COP cyclic is directly proportional to the maximum solar radiation. The system performance was found to be increased with the average ambient temperature. Finally, the proposed solar powered adsorption cooling systems can be used effectively under Al-Minya climatic conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/92060/solar-powered-adsorption-cooling-system-a-case-study-on-the-climatic-conditions-of-al-minya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92060.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2331</span> Effective Cooling of Photovoltaic Solar Cells by Inserting Triangular Ribs: A Numerical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Saadi">S.

A large amount of solar radiation is converted to heat, which should be dissipated by any cooling techniques. In the present study, the cooling is achieved by inserting triangular ribs in the duct. A comprehensive two-dimensional thermo-fluid model for the effective cooling of PV cells has been developed. It has been first carefully validated against experimental and numerical results available in the literature. A parametric analysis was then carried out about the influence of the number and size of the ribs, wind speed, solar irradiance and inlet fluid velocity on the average solar cell and outlet air temperatures as well as the thermal and electrical efficiencies of the module. Results indicated that the use of triangular ribbed channels is a very effective cooling technique, which significantly reduces the average temperature of the PV cell, especially when increasing the number of ribs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20cooling" title="effective cooling">effective cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20cell" title=" photovoltaic cell"> photovoltaic cell</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20ribs" title=" triangular ribs"> triangular ribs</a> </p> <a href="https://publications.waset.org/abstracts/90057/effective-cooling-of-photovoltaic-solar-cells-by-inserting-triangular-ribs-a-numerical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90057.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2330</span> TiO2/PDMS Coating With Minimum Solar Absorption Loss for Passive Daytime Radiative Cooling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhrigu%20Rishi%20Mishra">Bhrigu Rishi Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Sreerag%20Sundaram"> Sreerag Sundaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Nithin%20Jo%20Varghese"> Nithin Jo Varghese</a>, <a href="https://publications.waset.org/abstracts/search?q=Karthik%20Sasihithlu"> Karthik Sasihithlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have designed a TiO2/PDMS coating with 94% solar reflection, 96% IR emission, and 81.8 W/m2 cooling power for passive daytime radiative cooling using Kubelka Munk theory and CST microwave studio.

The concentrated solar energy is delivered to the solar cell from 20 to 100 W/cm². Some of this energy is converted to electricity, while the rest must be disposed of as a residual heat. Solar cells cooling should be a necessary part of CPV modeling because these systems allowed increasing the power received by the cell. This high power can rise the electrons’ potential causing the heating of the cell, which reduces the global module’s efficiency. This work consists of modeling a concentrating photovoltaic module with and without a cooling system. We have established a theoretical model based on energy balances carried out on a photovoltaic module using solar radiation concentration cells. Subsequently, we developed a calculation program on Matlab which allowed us to simulate the functioning of this module. The obtained results show that the addition of a cooling system to the module improves greatly the performance of our CPV system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20improvement" title=" performance improvement"> performance improvement</a> </p> <a href="https://publications.waset.org/abstracts/62511/modeling-of-a-concentrating-photovoltaic-module-with-and-without-cooling-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62511.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2328</span> Investigation on The Feasibility of a Solar Desiccant Cooling System in Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Zgalei">A.

The paper presents a short introduction for the desiccant systems. A mathematical model of a selected system has been developed and a simulation has been performed in order to investigate the system performance at different working conditions and an optimum design of the system structure is established.

The system is applied for Dalian, China, a location with cold climate conditions, where cooling demand is moderate, while space heating demand is slightly high. The study investigates the potential of a solar system installed and operated onsite in a detached single-family household to satisfy all necessary thermal loads. The hot water storage tank is also connected to an auxiliary heater (electric boiler) to supplement solar heating, when needed. The main purpose of the study is to model the overall system and contact a parametric study that will determine the optimum economic system performance in terms of design parameters. The system is compared, through a cost analysis, to an electric heat pump (EHP) system.

One of the most effective approaches to reduce the parasitic power consumption is to implement a natural draft dry cooling system instead of the standard utilized mechanical draft dry cooling system. In this paper, a thermo-economic analysis of a natural draft direct cooling system was performed based on a 100MWe commercial scale molten salt power plant. In this configuration with a natural draft direct cooling system, the exhaust steam from steam turbine flows directly to the heat exchanger bundles inside the natural draft dry cooling tower, which eliminates the power consumption of circulation pumps or fans, although the cooling tower shadows a portion of the heliostat field. The simulation results also show that compared to a mechanical draft cooling system the annual solar field efficiency is decreased by about 0.2% due to the shadow, which is equal to a reduction of approximately 13% of the solar field area. As a contrast, reducing the solar field size by 13% in purpose in a molten salt power plant with a natural draft drying cooling system actually will lead to a reduction of levelized cost of electricity (LCOE) by about 4.06% without interfering the power generated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20power%20tower" title="molten salt power tower">molten salt power tower</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20draft%20dry%20cooling" title=" natural draft dry cooling"> natural draft dry cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20power%20consumption" title=" parasitic power consumption"> parasitic power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20scale" title=" commercial scale"> commercial scale</a> </p> <a href="https://publications.waset.org/abstracts/93523/thermo-economic-analysis-of-a-natural-draft-direct-cooling-system-for-a-molten-salt-power-tower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2322</span> Performance Analysis of Solar Assisted Air Condition Using Carbon Dioxide as Refrigerant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile">Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferdinard%20Dika"> Ferdinard Dika</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi"> Mustafa Dagbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Abbasoglu"> Serkan Abbasoglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to model an air conditioning system that brings about effective cooling and reduce fossil fuel consumption with solar energy as an alternative source of energy. The objective of the study is to design a system with high COP, low usage of electricity and to integrate solar energy into AC systems. A hybrid solar assisted air conditioning system is designed to produce 30kW cooling capacity and R744 (CO₂) is used as a refrigerant. The effect of discharge pressure on the performance of the system is studied. The subcool temperature, evaporating temperature (5°C) and suction gas return temperature (12°C) are kept constant for the four different discharge pressures considered. The cooling gas temperature is set at 25°C, and the discharge pressure includes 80, 85, 90 and 95 bars. Copeland Scroll software is used for the simulation. A pressure-enthalpy graph is also used to deduce each enthalpy point while numerical methods were used in making other calculations. From the result of the study, it is observed that a higher COP is achieved with the use of solar assisted systems. As much as 46% of electricity requirements will be save using solar input at compressor stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title="air conditioning">air conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a> </p> <a href="https://publications.waset.org/abstracts/82514/performance-analysis-of-solar-assisted-air-condition-using-carbon-dioxide-as-refrigerant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2321</span> BLDC Motor Driven for Solar Photo Voltaic Powered Air Cooling System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Shobha%20Rani">D.

As buildings represent a considerable portion of energy use in Canada, application of distributed solar energy systems for heating and cooling may increase the amount of renewable energy use. Parabolic solar trough systems have seen limited deployments in cold northern climates as they are more suitable for electricity production in southern latitudes. Heat production by concentrating solar rays using parabolic troughs can overcome the poor efficiencies of flat panels and evacuated tubes in cold climates. A numerical dynamic model is developed to simulate an installed parabolic solar trough facility in Winnipeg. The results of the numerical model are validated using the experimental data obtained from this system. The model is developed in Simulink and will be utilized to simulate a tri-generation system for heating, cooling and electricity generation in remote northern communities. The main objective of this simulation is to obtain operational data of solar troughs in cold climates as this is lacking in the literature. In this paper, the validated Simulink model is applied to simulate a solar assisted absorption cooling system along with electricity generation using organic Rankine cycle (ORC) and thermal storage. A control strategy is employed to distribute the heated oil from solar collectors among the above three systems considering the temperature requirements. This modeling provides dynamic performance results using real time minutely meteorological data which are collected at the same location the solar system is installed. This is a big step ahead of the current models by accurately calculating the available solar energy at each time step considering the solar radiation fluctuations due to passing clouds. The solar absorption cooling is modeled to use the generated heat from the solar trough system and provide cooling in summer for a greenhouse which is located next to the solar field. A natural gas water heater provides the required excess heat for the absorption cooling at low or no solar radiation periods. The results of the simulation are presented for a summer month in Winnipeg which includes the amount of generated electric power from ORC and contribution of solar energy in the cooling load provision <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption%20cooling" title="absorption cooling">absorption cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20solar%20trough" title=" parabolic solar trough"> parabolic solar trough</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20community" title=" remote community"> remote community</a>, <a href="https://publications.waset.org/abstracts/search?q=validated%20model" title=" validated model"> validated model</a> </p> <a href="https://publications.waset.org/abstracts/27155/simulation-of-solar-assisted-absorption-cooling-and-electricity-generation-along-with-thermal-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2318</span> Performances Analysis and Optimization of an Adsorption Solar Cooling System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Allouache">Nadia Allouache</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of solar energy in cooling systems is an interesting alternative to the increasing demand of energy in the world and more specifically in southern countries where the needs of refrigeration and air conditioning are tremendous.

This study focuses on performances analysis and optimization of solar reactor of an adsorption cooling machine working with activated carbon-methanol pair. The modeling of the adsorption cooling machine requires the resolution of the equation describing the energy and mass transfer in the tubular adsorber that is the most important component of the machine. The results show the poor heat conduction inside the porous medium and the resistance between the metallic wall and the bed engender the important temperature gradient and a great difference between the metallic wall and the bed temperature; this is considered as the essential causes decreasing the performances of the machine.

Overheating of the PV modules reduces the open circuit voltage and the efficiency of the modules dramatically. In this work, water cooling is developed to enhance the performance of PV modules. Different scenarios are tested under UAE weather conditions: front, back and double cooling. A spraying system is used for the front cooling whether a direct contact water system is used for the back cooling. The experimental results are compared to a non-cooling module and the performance of the PV module is determined for different situations. A mathematical model is presented to estimate the theoretical performance and validate the experimental results with and without cooling. The experimental results show that the front cooling is more effective than the back cooling and may decrease the temperature of the PV module significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PV%20cooling" title="PV cooling">PV cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20methods" title=" cooling methods"> cooling methods</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20efficiency" title=" electrical efficiency"> electrical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20effect" title=" temperature effect"> temperature effect</a> </p> <a href="https://publications.waset.org/abstracts/34166/keynote-speaker-enhancing-the-performance-of-a-photovoltaic-module-using-different-cooling-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34166.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">497</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2316</span> Feasibility and Energy Efficiency Analysis of Chilled Water Radiant Cooling System of Office Apartment in Nigeria’s Tropical Climate City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasaq%20Adekunle%20Olabomi">Rasaq Adekunle Olabomi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> More than 30% of the global building energy consumption is attributed to heating, ventilation and air-conditioning (HVAC) due to increasing urbanization and the need for more personal comfort. While heating is predominant in the temperate regions (especially during winter), comfort cooling is constantly needed in tropical regions such as Nigeria. This makes cooling a major contributor to the peak electrical load in the tropics. Meanwhile, the high solar energy availability in the tropical climate region presents a higher application potentials for solar thermal cooling systems; more so, the need for cooling mostly coincides with the solar energy availability. In addition to huge energy consumption, conventional (compressor type) air-conditioning systems mostly use refrigerants that are regarded as environmental unfriendly because of their ozone depletion potentials; this has made the alternative cooling systems to become popular in the present time. The better thermal capacity and less pumping power requirement of chilled water than chilled air has also made chilled water a preferred option over the chilled air cooling system. Radiant floor chilled water cooling is particularly is also considered suitable for spaces such as meeting room, seminar hall, auditorium, airport arrival and departure halls among others. This study did the analysis of the feasibility and energy efficiency of solar thermal chilled water for radiant flood cooling of an office apartment in a tropical climate city in Nigeria with a view to recommend its up-scaling. The analysis considered the weather parameters including available solar irradiance (kWh/m2-day) as well as the technical details of the solar thermal cooling systems to determine the feasibility. Project cost, its energy savings, emission reduction potentials and cost-to-benefits ration are used to analyze its energy efficiency as well as the viability of the cooling system. The techno-economic analysis of the proposed system, carried out using RETScreen software shows that its viability in but SWOT analysis of policy and institutional framework to promote solar energy utilization for the cooling systems shows weakness such as poor infrastructure and inadequate local capacity for technological development as major challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooling%20load" title="cooling load">cooling load</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption%20cooling%20system" title=" absorption cooling system"> absorption cooling system</a>, <a href="https://publications.waset.org/abstracts/search?q=coefficient%20of%20performance" title=" coefficient of performance"> coefficient of performance</a>, <a href="https://publications.waset.org/abstracts/search?q=radiant%20floor" title=" radiant floor"> radiant floor</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20saving" title=" cost saving"> cost saving</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20reduction" title=" emission reduction"> emission reduction</a> </p> <a href="https://publications.waset.org/abstracts/191918/feasibility-and-energy-efficiency-analysis-of-chilled-water-radiant-cooling-system-of-office-apartment-in-nigerias-tropical-climate-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191918.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">24</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2315</span> Assessment of the Thermal Performance of a Solar Heating System on an Agricultural Greenhouse Microclimate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Arbaoui">Nora Arbaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Tadili"> Rachid Tadili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The substantial increase of areas cultivated under glasshouses compels the use of other natural heating and cooling procedures to make a profit as well as avoid both exorbitant fuel consumption and CO₂ emissions.

Various coating materials with different optical properties have been developed to improve the daytime radiative cooling performance. However, commercial cooling coatings comprising functional fillers with optical bandgaps within the solar spectral range suffers from severe intrinsic absorption, limiting their cooling performance. Fortunately, it has recently been demonstrated that introducing fluorescent materials into polymeric coatings can covert the absorbed sunlight to fluorescent emissions and hence increase the effective solar reflectance and cooling performance. In this paper, we experimentally investigate the key factors for fluorescence-assisted radiative cooling with TiO2-based white coatings. The surrounding TiO2 nanoparticles, which enable spatial and temporal light confinement through multiple Mie scattering, lead to Purcell enhancement of phosphors in the coating. Photoluminescence lifetimes of two phosphors (BaMgAl10O17:Eu2+ and (Sr, Ba)SiO4:Eu2+) exhibit significant reduction of ~61% and ~23%, indicating Purcell factors of 2.6 and 1.3, respectively. Moreover, smaller Stokes shifts of the phosphors are preferred to further diminish solar absorption. Field test of fluorescent cooling coatings demonstrate an improvement of ~4% solar reflectance for the BaMgAl10O17:Eu2+-based fluorescent cooling coating. However, to maximize solar reflectance, a white appearance is introduced based on multiple Mie scattering by the broad size distribution of fillers, which is visually pressurized and aesthetically bored. Besides, most colored pigments absorb visible light significantly and convert it to non-radiative thermal energy, offsetting the cooling effect. Therefore, current colored cooling coatings are facing the compromise between color saturation and cooling effect. To solve this problem, we introduced colored fluorescent materials into white coating based on SiO2 microspheres as a top layer, covering a white cooling coating based on TiO2. Compared with the colored pigments, fluorescent materials could re-emit the absorbed light, reducing the solar absorption introduced by coloration. Our work investigated the scattering properties of SiO2 dielectric spheres with different diameters and detailly discussed their impact on the PL properties of phosphors, paving the way for colored fluorescent-assisted cooling coting to application and industrialization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20reflection" title="solar reflection">solar reflection</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20emissivity" title=" infrared emissivity"> infrared emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=mie%20scattering" title=" mie scattering"> mie scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescent%20emission" title=" photoluminescent emission"> photoluminescent emission</a>, <a href="https://publications.waset.org/abstracts/search?q=radiative%20cooling" title=" radiative cooling"> radiative cooling</a> </p> <a href="https://publications.waset.org/abstracts/167284/effects-of-stokes-shift-and-purcell-enhancement-in-fluorescence-assisted-radiative-cooling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167284.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2313</span> Numerical Simulation of a Solar Photovoltaic Panel Cooled by a Forced Air System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamila%20Nebbali">Djamila Nebbali</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezki%20Nebbali"> Rezki Nebbali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ouibrahim"> Ahmed Ouibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the cooling of a photovoltaic panel (PV).

To do this, a fan provides forced circulation of air. Because the fan is supplied by the panel, it is necessary to determine the optimum operating point that unites efficiency of the PV with the consumption of the fan. For this matter, numerical simulations are performed at varying mass flow rates of air, under two extreme air temperatures (50°C, 25°C) and a fixed solar radiation (1000 W.m2) in a case of no wind. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20conversion" title="energy conversion">energy conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=balance%20energy" title=" balance energy"> balance energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title=" solar cell"> solar cell</a> </p> <a href="https://publications.waset.org/abstracts/15688/numerical-simulation-of-a-solar-photovoltaic-panel-cooled-by-a-forced-air-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15688.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2312</span> Sustainable Development of Adsorption Solar Cooling Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Allouache">N.

To study the effectiveness of this system, experiments are conducted in two similar agricultural greenhouses oriented north-south. The first greenhouse is equipped with an active solar system integrated into the double glazing of the greenhouse’s roof, while the second greenhouse has no system, it serves as a controlled greenhouse for comparing thermal and agronomic performance The solar system allowed for an average increase in the indoor temperature of the experimental greenhouse of 6°C compared to the outdoor environment and 4°C compared to the control greenhouse. This improvement in temperature has a favorable effect on the plants' climate and subsequently positively affects their development, quality, and production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20system" title="solar system">solar system</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20greenhouse" title=" agricultural greenhouse"> agricultural greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=heating" title=" heating"> heating</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a> </p> <a href="https://publications.waset.org/abstracts/158806/optimization-of-the-energy-management-for-a-solar-system-of-an-agricultural-greenhouse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158806.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2309</span> Modeling and Analysis of Solar Assisted Adsorption Cooling System Using TRNSYS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Wajahat">M.

This research is emphasized on solar assisted adsorption refrigeration system to provide comfort conditions for a building in Islamabad. The adsorption chiller can be driven by low grade heat at low temperature range (50 -80 °C) which is lower than that required for generator in absorption refrigeration system which may be furnished with the help of common flat plate solar collectors (FPC). The aim is to offset the total energy required for building’s heating and cooling demand by using FPC’s thus reducing dependency on primary energy source hence saving energy. TRNSYS is a dynamic modeling and simulation tool which can be utilized to simulate the working of a complete solar based adsorption chiller to meet the desired cooling and heating demand during summer and winter seasons, respectively. Modeling and detailed parametric analysis of the whole system is to be carried out to determine the optimal system configuration keeping in view various design constraints.

The AC35/methanol pair is the best pair comparing to the BPL/Ammoniac in terms of system performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon-methanol%20pair" title="activated carbon-methanol pair">activated carbon-methanol pair</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon-ammoniac%20pair" title=" activated carbon-ammoniac pair"> activated carbon-ammoniac pair</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20coefficients" title=" performance coefficients"> performance coefficients</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cooling%20system" title=" solar cooling system"> solar cooling system</a> </p> <a href="https://publications.waset.org/abstracts/169365/thermal-and-solar-performances-of-adsorption-solar-refrigerating-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169365.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2307</span> Performance Evaluation of Vermiculite as Adsorbent Material for Solar-Assisted Air-Conditioning in Tropical Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Mat%20Wajid">Norhayati Mat Wajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Murad%20Zainal%20Abidin"> Abdul Murad Zainal Abidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasila%20Jarimi"> Hasila Jarimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaruzaman%20Sopian"> Kamaruzaman Sopian</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Ibrahim"> Adnan Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Fazlizan"> Ahmad Fazlizan</a>, <a href="https://publications.waset.org/abstracts/search?q=Afif%20Safwan"> Afif Safwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solar-adsorption air-conditioning system (SADCS) is an alternative to the conventional vapor compression system (VCS). SADCS have advantages over VCS system, such as 1) a green cooling technology which utilizes solar energy to drive the adsorption/desorption cycle, 2) can be operated using green refrigerant HFC free pure water, 3) mechanically simpler, and 4) lower operating noise level since it has no moving parts other than the magnetic valves. Several advancements have been achieved in these fields in the last decade, but further research is still needed to escalate this technology to a practical level. Hence, this paper presents a literature survey and a review that add insights into the current state-of-the-art of SADCS technologies with emphasis on the practical researches that were conducted at the laboratory scale and commercial level. In this paper, the performance evaluation of vermiculite as adsorbent material for SADCS in tropical climate discussed in comparison to other adsorbent material such as silica gel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20cooling" title="adsorption cooling">adsorption cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=solar-assisted%20cooling" title=" solar-assisted cooling"> solar-assisted cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC" title=" HVAC"> HVAC</a>, <a href="https://publications.waset.org/abstracts/search?q=tropical%20climate" title=" tropical climate"> tropical climate</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20thermal" title=" solar thermal"> solar thermal</a> </p> <a href="https://publications.waset.org/abstracts/144652/performance-evaluation-of-vermiculite-as-adsorbent-material-for-solar-assisted-air-conditioning-in-tropical-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144652.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2306</span> Investigation of Solar Concentrator Prototypes under Tunisian Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moncef%20Balghouthi">Moncef Balghouthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Ben%20Amara"> Mahmoud Ben Amara</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdessalem%20Ben%20Hadj%20Ali"> Abdessalem Ben Hadj Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Amenallah%20Guizani"> Amenallah Guizani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concentrated solar power technology constitutes an interesting option to meet a part of future energy demand, especially when considering the high levels of solar radiation and clearness index that are available particularly in Tunisia. In this work, we present three experimental prototypes of solar concentrators installed in the research center of energy CRTEn in Tunisia. Two are medium temperature parabolic trough solar collector used to drive a cooling installation and for steam generation. The third is a parabolic dish concentrator used for hybrid generation of thermal and electric power. Optical and thermal evaluations were presented. Solutions and possibilities to construct locally the mirrors of the concentrator were discussed. In addition, the enhancement of the performances of the receivers by nano selective absorption coatings was studied. The improvement of heat transfer between the receiver and the heat transfer fluid was discussed for each application. <p class="card-text"><strong>Keywords:</strong> <a
