بررسي تجربي يك سيستم تركيبي آب شيرين‌كن خورشيدي تبخيري 1،5 ليتري با استفاده از لوله حرارتي و پنل خورشيدي

Experimental Investigation a type of evaporation-based solar desalination system 1.5 liter with the photovoltaic and heat pipe technologies

در اين مقاله به بررسي يك نوع آب شيرين‌كنخورشيدي تبخيري به منظور شيرين سازي آب‌شور پرداخته شده است. از اهداف اصلي اين مقاله ساخت تجربي دستگاه آب شيرين‌كن با بهره گيري از فناوري هاي پنل خورشيدي و لوله حرارتي همزمان در يك سيستم مي باشد، ظرفيت توليد آب شيرين 1،5 ليتر در روز و توان پنل خورشيدي 80 وات مي‌باشد. با توجه به بازده پايين تبديل انرژي خورشيدي به الكتريكي توسط سيستم فتوولتاييك، انرژي تلف شده در اين سيستم توسط لوله حرارتي بازيابي مي‌گردد تا علاوه بر كاهش دماي صفحه فتوولتاييك سبب افزايش راندمان آن شود.

With regard to the ever growing world population and the constant capacity of water resources, novel and trusted methods need to be implemented to preserve freshwater resources and also produce drinking water. In this study, an investigation was performed on a type of evaporation-based solar desalination system which was used to desalinate saline water. Among the aims of this study was the fabrication of a desalination system with the help of both solar panel and heat pipe technologies in a single system. After the fabrication of the desalination system, various parameters such as the amount of produced freshwater by distilled vapor on the glass covering and the surface temperature of the photovoltaic, heat pipe and glass cover were studied. Analysis of the effect of water depth in the basin and also the effect of the presence of a fan inside the reservoir were also performed and finally the amount of freshwater production was studied in passive and active situations. The results indicated that the optimum water depth was 5 cm and the freshwater production efficiency of the active configuration was 25% more than the passive state.
