摘要：

In order to improve the thermal utilization efficiency of the device and the service life of the collector, at the same time reduce the heat loss in the external heat transfer process and salt scaling in device, this paper studies a small solar seawater desalination system driven by CPC solar collector. Experimental findings: under steady-state conditions, the system can produce freshwater 7908 g/d, maximum hourly yield reaches 861 g/h at 12:00 noon and salt removing rate reaches 99.9% above, and the highest instantaneous performance coefficient GOR(gained output ratio) reaches 1.14, and the highest instantaneous useful energy reaches 1114.9 W, from 11:30-16:00, the humidity of humidification chamber is always more than 90%. When the maximum solar irradiance reaches the maximum 1072 W/m2, the maximum humidity of humidification chamber is 97%. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
