英文摘要： At present, structure design of membrane module, Process flow optimization and integration methods of low grade energy system have been significant restraints to the development of membrane distillation technology. Because of the higher energy consumption caused by latent heat loss of phase change, this project aims to design a new membrane distillation coupling system including The solar-photothermal system, optoelectronic system and semiconductor refrigeration system, which is based on the new parallel type membrane module, and to develop the solar spotlighting technology used in low temperature field. This project intends to use the solar parabolic-groove spotlighting system to heating and power generation, and to lay pipe cooling on the photoelectric board for heat transfer preheating the heat side unprocessed working medium of membrane distillation system. The cold cavity of membrane distillation component uses semiconductor refrigeration which is low energy consumption. This project will analyse performance of the collector acted by the combination of multi-scale comprehensive factors such as flow characteristics, radiation characteristics, operation parameters, system structure parameters etc, to explore the intrinsic operation rules of solar collector system. Also, it will design cold cavity matched to t
