In recent years, solar absorption air-conditioning system have become an important directions of solar energy utilization. Improving solar energy utilization efficiency can effectively solve the problems of energy crisis. In traditional thermal method, low efficiency suffer from the heat loss and the cost is expensive. To improve solar energy utilization efficiency, a solar steam regeneration method was proposed: with corresponding material structure that can locate solar energy in the event of evaporation and minimize heat loss. The material structure has a high absorption in the solar spectrum, thermally insulating, hydrophilic surfaces and interconnected pores which allows the fluid flow to and from the structure. The solar steam regeneration method can be used in solar absorption air-conditioning system. Models have been developed and some important parameters have been investigated. The influence of concentration and absorbent variety has been analyzed in the experiments. Preliminary testing of the evaporation process has been carried out. It found the solar energy utilization efficiency with solar steam method has potential to further increase by 2 or 3 times. The solar energy utilization efficiency of the solar steam regeneration system approached 46%. That indicates it a promising choice for solar desalination and absorption system.
