| Abstract |
This paper describes an experimental study on small-scale sorption refrigerator. Silica gel(type A) as an adsorbent, HFC-134a as a refrigerant were selected for a sorption refrigerator. The focus of the design was to reduce the cycle time of the sorption refrigerator. Through the experiment, pressure and temperature variations in the adsorber were measured and the performance of refrigerator was predicted. In this paper, the small-scale sorption refrigerator operates with the cycle time of 480s. Its predicted cooling capacity is 25W at －15 ℃ and COP is 0.23. |
