The present study introduces an innovative method for fresh water and electricity generation in the isolated regions. This proposed system couples a concentrated photovoltaic (CPV) unit with a membrane distillation (MD) unit. The CPV unit converts solar energy into electrical energy with conversion efficiency of about 40%. The rest is converted to thermal energy, which may cause cells degradation if temperature exceeds manufacturer limits. An intermediate fluid is used as a coolant which transfers the excess energy to the feed of the MD unit through a heat exchanger. The generated thermal energy in the HCPV cells is used as the driving force for the distillation phenomena in the MD unit. Numerical models were built to simulate the hybrid system. It was found that, at a solar radiation concentration ratio of 1000 suns, the coolant flow rate should exceed 150 g/min for a maximum cell temperature less than 349 K. This arrangement should produce 177 W electric power, and 308 W thermal heat transferred to the coolant. At these conditions, the feed inlet temperature reaches about 323 K, at which, the MD unit produces about 5.88 kg/m².h of pure water, thus allowing the system to simultaneously produce electricity and pure water for isolated coastal regions.

本研究介绍了一种在偏远地区进行淡水和电力生产的创新方法。该提议的系统将浓缩光伏（CPV）单元与膜蒸馏（MD）单元耦合。CPV单元将太阳能转换为电能，转换效率约为40％。其余的转换为热能，如果温度超过制造商的限制，可能会导致电池退化。中间流体被用作冷却剂，该冷却剂将多余的能量通过热交换器传递给MD单元的进料。HCPV电池中产生的热能用作MD单元中蒸馏现象的驱动力。建立了数值模型来模拟混合动力系统。结果发现，在太阳辐射集中度为1000个太阳的情况下，对于最高电池温度低于349 K的情况，冷却剂流速应超过150 g / min。这种布置应产生177 W的电能，并向冷却剂传递308 W的热能。在这些条件下，进料口温度达到约323 K，在这种情况下，MD装置的产量约为5.88 kg / m² h的纯净水，因此系统可以同时为偏远的沿海地区发电和提供纯净水。
