align="justify">The Parabolic Trough Test Loop (PTTL) facility is implemented in a 420mx180m plot of the PSA and it is composed of two solar fields:</p> <ul> <li> the North field is designed to install with a E-W orientation complete parabolic trough collectors with a maximum unit length of 180 m. Up to four complete collectors can be installed in parallel.</li> <li> the South field is designed to install complete loops of parabolic trough collectors (PTCs), i.e. several collectors connected in series, with a maximum length of 640 m and oriented North-South. Up to four complete loops can be installed in parallel. </li> </ul> <p>Each field is provided with a complete oil circuit installed on a 30mx30m concrete platform between the two fields, and both circuits share: an oil expansion tank with a capacity of 30 m3, a gas-fired oil heater with a thermal power of 250 kW, a meteorological station equipped with solar radiation, ambient temperature and wind sensors, and the data acquisition system (DAS). Additionally to these common elements, the oil circuit associated to the North and South fields are composed of:</p> <ul><li> North field: one oil pump (75 m3/h) provided with speed control, one oil cooler refrigerated by air (1.5 MWt) able to cold the oil down to 70掳C when the ambient air temperature is 40掳C, oil piping connecting the circuit to the common elements (i.e., expansion tank and oil heater).</li> <li> <p>South field: one oil pump (125 m3/h) provided with speed control, one oil cooler refrigerated by air (4 MWt), oil piping connecting the circuit to the common elements (i.e., expansion tank and oil heater).</li></ul> Each oil circuit is also provided with an oil draining tank big enough to receive all the oil existing in the circuit, a complete set of instrumentation to monitor: oil mass flow, pressures and temperatures, as well as control valves to regulate the oil flow to desired values according to the tests.</p> <p>This outdoor life-size test facility offers the following capacities:</p> <ul><li>qualification of complete PTC prototypes assessing their optical peak efficiency, incidence angle modifier and thermal losses,</li> <li>evaluation of durability and reliability of PTC mirrors, receiver tubes, ball-joints, flex hoses, sun tracking systems and all the elements installed in complete rows of collectors,</li> <li>Evaluation of PTC solar field control algorithms</li> </ul> <figure><img src="../images/pttl.png" alt="" width="520"></figure> <figcaption>Simplified scheme of the PTTL facility</figcaption> </article> </section> <nav class="lateral"> <article><link rel="stylesheet" type="text/css" href="/css/menuprojects.css"> <div id="cssmenuareas"> <ul> <li><a href="/en/facilities/parabolic_trough/diss.php">A1.- DISS</a></li> <li><a href="/en/facilities/parabolic_trough/htf.php">A2.- HTF</a></li> <li><a href='/en/facilities/parabolic_trough/prometeo.php'>A3.- PROMETEO</a></li> <li><a href='/en/facilities/parabolic_trough/pttl.php'>A4.- PTTL</a></li> <li><a href='/en/facilities/parabolic_trough/tcp100.php'>A5.- TCP-100</a></li> <li><a href='/en/facilities/parabolic_trough/ifl.php'>A6.- IFL</a></li> <li><a href='/en/facilities/parabolic_trough/nep.php'>A7.-NEP</a></li> <li><a href='/en/facilities/parabolic_trough/lavec.php'>A8.- LAVEC</a></li> </ul> </div> </article> </nav> <!-- #EndEditable --> </div> </div> <footer> <footer class="caja"> <img src=/images/phone.png align=left width="60"><p>+34 950 387 900</p> </footer> <footer class="caja"> <img src=/images/mail.png align=left width="60"><p><a href="mailto:info@psa.es">info@psa.es</a></p> </footer> <footer class="caja"> <img src=/images/address.png align=left width="60"><p>Ctra. de Senés km. 4,5<br> Tabernas (04200)<br> Almería</p></footer> <br clear="all"> <a href="https://twitter.com/psaciemat"><img src="/images/twitter.png" width="40"></a> <a href="https://www.facebook.com/plataformasolardealmeria"><img src="/images/facebook.png" width="40"></a> <a href="https://es.linkedin.com/company/psaciemat"><img src="/images/linkedin.png" width="40"></a> <a href="https://www.youtube.com/@plataformasolardealmeria"><img src="/images/youtube.png" width="40"></a> <div align="center"> <br> <span>Plataforma Solar de Almería</span><br> <div id="piemap">| <a href="/en/legaldocument.php">Legal Document</a> |</div> </div> <div id="overbox3"> <div id="infobox3"> <p>We use our own and third-party cookies (Google Analytics) to collect statistical information and about your preferences by analyzing your browsing habits.
