【Abstract】 The commercial application of the solar-powered adsorption refrigeration system is restricted due to its relatively lower COP and higher cost.In this paper,a general overview of recent development of the solar-powered adsorption refrigeration technology is presented.Many adsorbent-adsorbate working pairs recently developed for solar-powered adsorption and the characteristics of system cycles and adsorbent beds are introduced in detail.It is indicated that the optimization of the components is very important to a solar-powered adsorption refrigeration system,especially the key components,such as the adsorbent bed,the condenser,and the evaporator.In addition,the development of the valveless system ought to be promoted,which has a more stable performance and is easily to be operated.At the same time,more attention should also be paid to the study of integrating solar powered adsorption refrigeration into buildings in order to conform to the requirements of building unity.In the end,the promising prospects of the development of solar powered adsorption refrigeration technology are discussed.更多还原
