The working principle and design method of a small solar adsorption refrigeration system which driven by a new solar concentrating device is presented in this paper. The performance of the new solar concentrating device in the actual weather conditions was tested and the experimental measurement curves were given. Experimental results show that the efficiency of this solar concentrating device can be achieved about 42%. The performance of the refrigeration system was also estimated in this paper. The results show that due to the system having the advantages such as high-temperature operation, high efficiency of solar concentrator and so on,the coefficient of performance (COP) reached 0. 62,so it has good market prospects.
