Abstract

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