R404A、R407C在船用空调中替代R22的实验分析

摘要

以单元式空调的IPLV测试工况为依据,进行某船用空调系统R404A和R407C替代R22的性能测试,得出了吸、排气压力,排气温度,制冷量,功耗及COP随冷凝器进水温度的变化规律.%Based on IPLV working conditions of unitary air conditioner, the performance experiments on a marine air - condi-tioner using R404A and R407C as an alternative refrigerant to R22 were conducted. Relation between inlet water temperature of condenser and parameters including suction and discharge pressure, discharge temperature, cooling capacity, power input and COP was acquired.
