摘　　要：为提高淡水产量,文章提出了一种太阳能低压蒸馏海水系统,并对其进行了理论分析及实验测试。实验测试了不同压力对淡水产量及系统瞬时集热效率的影响,同时,探究了不同压力、蒸馏室温度等条件下淡水产量及系统瞬时集热效率的最优值。结果表明,当蒸馏室内压力为0.04 MPa,温度为80.3℃时,淡水产量达到最高值2.7 kg/h,系统瞬时集热效率高达58.86%,全天淡水产量达到10.36 kg。In order to increase the production of fresh water, a solar low-pressure distillation seawater desalination system was proposed, meanwhile, theoretical analysis and experimental tests were carried out. Experiments have tested the effects of different pressures on the production of fresh water and the instantaneous heat collection efficiency of the system, and explored the optimal value of the production of fresh water and the instantaneous heat collection efficiency of the system under different pressures, distillation chamber temperatures conditions. The results showed that when the pressure in the distillation chamber is 0.04 MPa and the temperature is 80.3 ℃, the freshwater output reaches the highest value of 2.7 kg/h, the instantaneous heat collection efficiency of the system is as high as 58.86%, and the daily freshwater output reaches 10.36 kg.
