| Summary: | <p>This paper deals with the conception, design, and construction of a prototype of a Linear Fresnel Reflector (LFR) coupled with a Multi-Effect Distillation system intended to sea-water desalination. Our system consists of 11 flat glass mirrors with a total reflecting surface of 1.5 m<sup>2</sup>, and a tubular receiver-absorber located inside an evacuated glass tube equipped with a secondary reflector. To deal with the discontinuity in heat production, a thermal storage system was built using locally abundant materials such as a bed-rock. An experimental study of the thermal and optical performances of the system has been assessed to quantify the overall efficiency of our prototype. The salient features of our study include a stagnation temperature as high as 263 °C, the overall heat transfer coefficient reached 22.91 W/m²K, and the estimated collector’s efficiency at an operating temperature of 125°C was 56%. TRNSYS simulation of an LFR system similar to the proposed prototype was conducted. It shows that the system's thermal output is highly influenced by both tank size and flow rate.</p><p> </p><p><strong>Received on, 26 March 2025 </strong></p><p><strong>Accepted on, 10 May 2025 </strong></p><p><strong>Published on, 15 May 2025</strong></p> |
