Effects of the air volume on cooling performance of a refrigeration system

In order to solve the problem of poor refrigeration performance during operation system under low temperature conditions, this paper designs a test bench study effect different air volumes on cooling capacity conditions 32?C outside warehouse and -10?C inside warehouse. The results show that when volume condenser is set 65% unit evaporator 100%, 8.62 kW, compressor power 1.88 COP 4.55 energy efficiency ratio 1.64. comprehensive consideration, can not only ensure best but also save considerable consumption.
