Depending on the mode of operation of the GCHPs, GHEs dissipate or absorb heat from the ground. For sizing the GHE the thermal properties of the ground need to be known. This paper gives information about the density, thermal conductivity, specific heat and thermal diffusivity of various lithologies encountered in Cyprus with various relations between these properties being examined through comparison and modeling. The results show that the most important correlation is the one encountered between thermal conductivity and thermal diffusivity with both properties showing similar response to the inlet and outlet flow temperature of vertical and horizontal heat exchangers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground%20heat%20exchangers" title="ground heat exchangers">ground heat exchangers</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20thermal%20conductivity" title=" ground thermal conductivity"> ground thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20thermal%20diffusivity" title=" ground thermal diffusivity"> ground thermal diffusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20thermal%20properties" title=" ground thermal properties"> ground thermal properties</a> </p> <a href="https://publications.waset.org/abstracts/2459/thermal-properties-of-the-ground-in-cyprus-and-their-correlations-and-effect-on-the-efficiency-of-ground-heat-exchangers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2459.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">380</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">6375</span> A Literature Review of the Trend towards Indoor Dynamic Thermal Comfort</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20Katungyi">James Katungyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Steady State thermal comfort model which dominates thermal comfort practice and which posits the ideal thermal conditions in a narrow range of thermal conditions does not deliver the expected comfort levels among occupants. Furthermore, the buildings where this model is applied consume a lot of energy in conditioning. This paper reviews significant literature about thermal comfort in dynamic indoor conditions including the adaptive thermal comfort model and alliesthesia. A major finding of the paper is that the adaptive thermal comfort model is part of a trend from static to dynamic indoor environments in aspects such as lighting, views, sounds and ventilation. Alliesthesia or thermal delight is consistent with this trend towards dynamic thermal conditions. It is within this trend that the two fold goal of increased thermal comfort and reduced energy consumption lies. At the heart of this trend is a rediscovery of the link between the natural environment and human well-being, a link that was partially severed by over-reliance on mechanically dominated artificial indoor environments. The paper concludes by advocating thermal conditioning solutions that integrate mechanical with natural thermal conditioning in a balanced manner in order to meet occupant thermal needs without endangering the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20thermal%20comfort" title="adaptive thermal comfort">adaptive thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=alliesthesia" title=" alliesthesia"> alliesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20environment" title=" natural environment"> natural environment</a> </p> <a href="https://publications.waset.org/abstracts/93485/a-literature-review-of-the-trend-towards-indoor-dynamic-thermal-comfort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93485.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">219</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">6374</span> Thermal Analysis of Photovoltaic Integrated Greenhouse Solar Dryer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumit%20Tiwari">Sumit Tiwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Tripathi"> Rohit Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=G.%20N.%20Tiwari"> G.

This presence makes the study of this area at both High School and University levels a very widely explored topic in the literature. However, a lot of important concepts to a meaningful understanding of the world are neglected at the expense of a traditional approach with senseless algebraic problems. In this work, we intend to show how the introduction of new technologies in the classroom, namely thermal cameras, can work in our favor to make a clearer understanding of many of these concepts, such as thermal conductivity. The use of thermal cameras in the classroom tends to diminish the everlasting abstractness in thermal phenomena as they enable us to visualize something that happens right before our eyes, yet we cannot see it. In our study, we will provide the same amount of heat to metallic cylindrical rods of the same length, but different materials in order to study the thermal conductivity of each one. In this sense, the thermal camera allows us to visualize the increase in temperature along each rod in real time enabling us to infer how heat is being transferred from one part of the rod to another. Therefore, we intend to show how this approach can contribute to the exposure of students to more enriching, intellectually prolific, scenarios than those provided by traditional approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teaching%20physics" title="teaching physics">teaching physics</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20cameras" title=" thermal cameras"> thermal cameras</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20physics" title=" thermal physics"> thermal physics</a> </p> <a href="https://publications.waset.org/abstracts/52305/an-attempt-to-improve-students-understanding-on-thermal-conductivity-using-thermal-cameras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52305.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">282</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">6370</span> Thermal Stability and Insulation of a Cement Mixture Using Graphene Oxide Nanosheets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasser%20A.%20M.%20Habib">Nasser A.

The composites were analyzed using Fourier transmission infrared, thermo-gravimetric analysis, and field emission scanning electron microscopy. Results showed that GO significantly improved specific heat by 32%, reduced thermal conductivity by 16%, and reduced thermal decomposition to only 3% at a concentration of 1.2 wt%.

An Auckland school normally does not need air conditioning for cooling during the summer and only needs heating during the winter.

This field study of testing indoor and outdoor air temperatures, relative humidity and indoor surface temperatures of three classrooms with different envelopes were carried out in the Avondale College during the winter months in 2013. According to the field study data, this study is to compare and evaluate winter thermal performance and indoor thermal conditions of school buildings with different envelopes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20envelope" title="building envelope">building envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20mass%20effect" title=" building mass effect"> building mass effect</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20thermal%20comfort" title=" building thermal comfort"> building thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20thermal%20performance" title=" building thermal performance"> building thermal performance</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20building" title=" school building "> school building </a> </p> <a href="https://publications.waset.org/abstracts/18103/field-study-for-evaluating-winter-thermal-performance-of-auckland-school-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18103.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">428</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">6368</span> A Case for Introducing Thermal-Design Optimisation Using Excel Spreadsheet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20El-Awad">M.

Thermal-design optimisation is an iterative process which involves the evaluation of many thermo-physical properties that vary with temperature and/or pressure. Therefore, suitable modelling software, such as Engineering Equation Solver (EES) or Interactive Thermodynamics (IT), is usually used for this purpose. However, such proprietary applications may not be available to many educational institutions in developing countries. This paper presents a simple thermal-design case that demonstrates how the principles of thermo-fluids and economics can be jointly applied so as to find an optimum solution to a thermal-design problem. The paper describes the solution steps and provides all the equations needed to solve the case with Microsoft Excel. The paper also highlights the advantage of using VBA (Visual Basic for Applications) for developing user-defined functions when repetitive or complex calculations are met. VBA makes Excel a powerful, yet affordable, the computational platform for introducing various engineering principles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering%20education" title="engineering education">engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20design" title=" thermal design"> thermal design</a>, <a href="https://publications.waset.org/abstracts/search?q=Excel" title=" Excel"> Excel</a>, <a href="https://publications.waset.org/abstracts/search?q=VBA" title=" VBA"> VBA</a>, <a href="https://publications.waset.org/abstracts/search?q=user-defined%20functions" title=" user-defined functions"> user-defined functions</a> </p> <a href="https://publications.waset.org/abstracts/3804/a-case-for-introducing-thermal-design-optimisation-using-excel-spreadsheet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3804.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">375</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">6367</span> Thermal Fatigue Behavior of Austenitic Stainless Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jung-Ho%20Moon">Jung-Ho Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Continually increasing working temperature and growing need for greater efficiency and reliability of automotive exhaust require systematic investigation into the thermal fatigue properties especially of high temperature stainless steels.

In this paper, we quantify the total thermal resistance of a graphene-based device by series resistance model and show that the thermal resistance at the interface of graphene and substrate contributes to more than 50% of the total resistance. Weak Van der Waals interactions at the interface and dissimilar phonon vibrational modes create this thermal resistance, allowing less heat to flow across the interface. We compare our results with commonly used materials and interfaces, demonstrating the role of the interface as a potential application for heat guide or block in a 2D material-based device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D%20material" title="2D material">2D material</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductance" title=" thermal conductance"> thermal conductance</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20resistance" title=" thermal resistance"> thermal resistance</a> </p> <a href="https://publications.waset.org/abstracts/150149/total-thermal-resistance-of-graphene-oxide-substrate-stack-role-of-interfacial-thermal-resistance-in-heat-flow-of-2d-material-based-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150149.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">6365</span> A Design of the Organic Rankine Cycle for the Low Temperature Waste Heat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Fra%C5%88a">K.

In the development process of new micromirror systems, assessing the extent of energy loss due to thermal damping accurately and predicting the performance of the system is very essential. In this paper, the depth of the thermal penetration layer at different eigenfrequencies and the temperature variation distributions surrounding a vibrating micromirror is analyzed. The thermal penetration depth corresponds to the thermal boundary layer in which energy is lost which is a measure of the thermal damping is found out. The energy is mainly dissipated in the thermal boundary layer and thickness of the layer is an important parameter. The detailed thermoacoustics is used to model the air domain surrounding the micromirror. The thickness of the boundary layer, temperature variations and thermal power dissipation are analyzed for a Si based torsional mode micromirror. It is found that thermal penetration depth decreases with eigenfrequency and hence operating the micromirror at higher frequencies is essential for reducing thermal damping. The temperature variations and thermal power dissipations at different eigenfrequencies are also analyzed. Both frequency-response and eigenfrequency analyses are done using COMSOL Multiphysics software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eigen%20frequency%20analysis" title="Eigen frequency analysis">Eigen frequency analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=micromirrors" title=" micromirrors"> micromirrors</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20damping" title=" thermal damping"> thermal damping</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoacoustic%20interactions" title=" thermoacoustic interactions"> thermoacoustic interactions</a> </p> <a href="https://publications.waset.org/abstracts/68224/analysis-of-thermal-damping-in-si-based-torsional-micromirrors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68224.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">365</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">6360</span> Investigation on the Thermal Properties of Magnesium Oxychloride Cement Prepared with Glass Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Zgueb">Rim Zgueb</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Yacoubi"> Noureddine Yacoubi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to investigate the thermal property of magnesium oxychloride cement (MOC) using glass powder as a substitute.

That device is a thermal diode. It is well known that heat transfer in solids basically depends on the electrical, magnetic and crystalline nature of materials via electrons, magnons and phonons as thermal energy carriers respectively. In the present research, we have synthesized polycrystalline Ni-Cu alloys and identified the Curie temperatures; and we have observed that by way of secondary phase transitions, it is possible manipulate the heat conduction in solid state thermal diodes via transition temperature. In this sense, we have succeeded in developing solid state thermal diodes with a control gate through the Curie temperature via the activation and deactivation of magnons in Ni-Cu ferromagnetic alloys at room temperature. Results show thermal diodes with thermal rectification factors up to 1.5. Besides, the performance of the electrical rectifiers can be controlled by way of alloy Cu content; hence, lower Cu content alloys present enhanced thermal rectifications factors than higher ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20rectification" title="thermal rectification">thermal rectification</a>, <a href="https://publications.waset.org/abstracts/search?q=Curie%20temperature" title=" Curie temperature"> Curie temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=ferromagnetic%20alloys" title=" ferromagnetic alloys"> ferromagnetic alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=magnons" title=" magnons"> magnons</a> </p> <a href="https://publications.waset.org/abstracts/71896/synthesis-and-characterization-of-ferromagnetic-ni-cu-alloys-for-thermal-rectification-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71896.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">246</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">6358</span> Development of Water-Based Thermal Insulation Paints Using Silica Aerogel </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%20Yanru">Lu Yanru</a>, <a href="https://publications.waset.org/abstracts/search?q=Handojo%20Djati%20Utomo"> Handojo Djati Utomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Xi%20Jiang"> Yin Xi Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Xiaodong"> Li Xiaodong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Insulation plays a key role in the sustainable building due to the contribution of energy consumption reduction. Without sufficient insulation, a great amount of the energy used to heat or cool a building will be lost to the outdoors. In this study, we developed a highly efficient thermal insulation paint with the incorporation of silica aerogel. Silica aerogel, with a low thermal conductivity of 0.01 W/mK, has been successfully prepared from the solid waste from the incineration plants. It has been added into water-based paints to increase its thermal insulation properties. To investigate the thermal insulation performance of silica aerogel additive, the paint samples were mixed with silica aerogel at different sizes and with various portions. The thermal conductivity, water resistance, thermal stability and adhesion strength of the samples were tested and evaluated. The thermal diffusivity measurements proved that adding silica aerogel additive could improve the thermal insulation properties of the paint significantly.

Thermal conductivity at 12, 15 and 18 MAP ranged 0.4770 W/m.K to 0.6052W/m.K; 0.4804 W/m.K to 0.5530 W/m.K and 0.3764 to 0.6102 W/m.K respectively, thermal diffusivity from 1.588 to 2.426 x 10-7m2/s; 1.290 to 2.010 x 10-7m2/s and 0.1692 to 4.464 x 10-7m2/s and specific heat capacity from 2.3626 to 3.8991 kJ/kg.K; 1.8110 to 3.9703 kJ/kgK and 1.7311 to 3.8830 kJ/kg.K respectively within the range of moisture content studied across the varieties. None of the samples over the ages studied showed similar or definite trend in variation with others across the moisture content. However, second order polynomial models fitted all the data. Age on the other hand had a significant effect on the three thermal properties studied for TME 419 but not on thermal conductivity of TMS30572 and specific heat capacity of TMS 0326.

The nanofluids were prepared using single step method (i.e. by dispersing nanoparticle directly in base fluid) which was gathered in ultrasonic device for approximately 7 hours. The transient hot-wire laser beam displacement technique was used to measure the thermal conductivity and thermal diffusivity of the prepared nanofluids. The thermal conductivity and thermal diffusivity were obtained by fitting the experimental data to the numerical data simulated for aluminum oxide in distilled water. The results show that the thermal conductivity and thermal diffusivity of nanofluids increases in non-linear behavior as the particle size increases. While, the thermal conductivity and thermal diffusivity of Al2O3 nanofluids was observed increasing linearly with concentration as the volume fraction concentration increases. We believe that the interfacial layer between solid/fluid is the main factor for the enhancement of thermal conductivity and thermal diffusivity of Al2O3 nanofluids in the present work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transient%20hot%20wire-laser%20beam%20technique" title="transient hot wire-laser beam technique">transient hot wire-laser beam technique</a>, <a href="https://publications.waset.org/abstracts/search?q=Al2O3%20nanofluid" title=" Al2O3 nanofluid"> Al2O3 nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size" title=" particle size"> particle size</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20fraction%20concentration" title=" volume fraction concentration"> volume fraction concentration</a> </p> <a href="https://publications.waset.org/abstracts/3987/effect-of-particles-size-and-volume-fraction-concentration-on-the-thermal-conductivity-and-thermal-diffusivity-of-al2o3-nanofluids-measured-using-transient-hot-wire-laser-beam-deflection-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3987.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">550</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">6352</span> An Approach for Thermal Resistance Prediction of Plain Socks in Wet State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Mansoor">Tariq Mansoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Lubos%20Hes"> Lubos Hes</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Bajzik"> Vladimir Bajzik </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Socks comfort has great significance in our daily life. This significance even increased when we have undergone a work of low or high activity. It causes the sweating of our body with different rates. In this study, plain socks with differential fibre composition were wetted to saturated level. Then after successive intervals of conditioning, these socks are characterized by thermal resistance in dry and wet states. Theoretical thermal resistance is predicted by using combined filling coefficients and thermal conductivity of wet polymers instead of dry polymer (fibre) in different models. By this modification, different mathematical models could predict thermal resistance at different moisture levels. Furthermore, predicted thermal resistance by different models has reasonable correlation range between (0.84 -0.98) with experimental results in both dry (lab conditions moisture) and wet states.

In this study, we explored the thermal environment in infant facilities classrooms for infants and children aged 1-5 and evaluated their thermal comfort. An infant facility in Fukuoka, Japan was selected for a case study to capture the infant and children’s thermal comfort characteristics in summer and winter from August 2019 to February 2020. Previous studies have pointed out using PMV indices to evaluate the thermal comfort for children could create errors that may lead to misleading results. Thus, to grasp the actual thermal environment and thermal comfort characteristics of infants and children, we retrieved the operative temperature of each child through the thermal model, based on the sensible heat transfer from the skin to the environment, and the measured classroom indoor temperature, relative humidity, and pocket temperature of children’s shorts. The statistical and comparative analysis of the results shows that (1) the operative temperature showed a large individual difference among children, with the maximum reached 6.25 °C. (2) The children might feel slightly cold in the classrooms in summer, with the frequencies of operative temperature within the interval of 26-28 ºC were only 5.33% and 16.6% for children respectively. (3) The thermal environment around children is more complicated in winter the operative temperature could exceed or fail to reach the thermal comfort temperature zone (20-23 ºC interval). (4) The environmental conditions surrounding the children may account for the reduction of their thermal comfort. The findings contribute to improving the understanding of the infant and children’s thermal comfort and provide valuable information for designers and governments to develop effective strategies for the indoor thermal environment considering the perspective of children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infant%20and%20children" title="infant and children">infant and children</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20environment" title=" thermal environment"> thermal environment</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20model" title=" thermal model"> thermal model</a>, <a href="https://publications.waset.org/abstracts/search?q=operative%20temperature." title=" operative temperature."> operative temperature.</a> </p> <a href="https://publications.waset.org/abstracts/148343/basic-study-on-a-thermal-model-for-evaluating-the-environment-of-infant-facilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148343.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">119</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">6349</span> The Effect of the Incorporation of Glass Powder into Cement Sorel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Zgueb">Rim Zgueb</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Yacoubi"> Noureddine Yacoubi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work concerns thermo-mechanical properties of cement Sorel mixed with different proportions of glass powder.
