Abstract

A new solar solid adsorption refrigeration system is established in this paper, and the variation relationship between the adsorbent bed temperature and pressure with time are analyzed, and the effects of adsorbent bed condensing pressure on the system performance is researched. Results show that, under the same working conditions, when the condensing pressure is 39 kPa, the daily ice-making capacity of system reach to 5.5 kg with the refrigerating capacity of 2.26 MJ; And when the condensing pressure is 63 kPa, the ice-making capacity of system is only for 3 kg with the refrigerating capacity of 1.48 MJ; The refrigerating capacity of the former is 1.5 times of the latter.
