摘　　要：对R410A与R22的热物理性质进行了理论分析,实验研究了R410A风冷热泵冷热水机组变出水温度工况的制热性能。在出水温度为35℃-55℃的范围内,进行了机组制热量、输入功率、COP、排气压力、吸气压力、压比、排气温度、吸气温度、冷凝温度、蒸发温度等特性参数的测试,得出了各特性参数随出水温度变化的规律。The thermophysieal properties of R22 and R410A were analyzed. The performance of a R410A air soure heat-pump was studied experimentally with varied supply hot water temperature. Heating capacity, power input, COP, discharge pressure, suction pressure, pressure ratio, discharge temperature, suction temperature condensing temperature and evaporating temperature were measurd in the supply wager temperature of 35 ℃ -55 ℃,their relation with supply water temperature were obtained.
