摘　　要：对空气源热泵热水器在标准工况和低温工况下的性能进行了试验研究,并分析了进水温度对排气压力、排气温度、消耗功率、热效率的影响规律。结果表明,排气压力、排气温度和消耗功率随着进水温度的升高而增加,制热功率和性能系数随着进水温度的升高而降低;标准工况下的性能优于低温工况下的性能。An experiment was analyzed on the performance of air-source heat pump heater in two different conditions, discharge pressure, discharge temperature, power input and coefficient of performance （COP） had been test under different ambient temperature. The results shows that discharge pressure, discharge temperature and power input are increasing with the heating water temperature, the heat amount and coefficient of performace are decreasing with the heating water temperature;in credit condition,the coefficient is better than low temperature condition.
