摘　　要：本文介绍了热回收型空气源热泵机组工作原理,提出了该系统的合理运行模式,并对热回收型热泵机组在不同运行工况下的性能进行了实验研究,研究了生活热水温度的变化对制冷系统性能的影响。夏季工况下,机组能够对冷凝热实现有效的回收利用,机组综合性能系数随着生活热水温度变化,平均达到3.39。冬季工况下可实现同时提供空调供暖和生活热水加热,但应合理设定生活热水进水温度。过渡季节换向工况,加热生活热水的性能系数为1.25。The principle and the structure of air-source heat pump with condensing heat recovery system （ASHPHR） were introduced, and the process modes at different status were put forward. An experimental study was carried out to study the system performance in the condition of different status. The impact of domestic hot water temperature on the seasonal performances of ASHPHR was mainly analyzed. In summer, ASHPHR can recover the condensing heat effectively. COPa＋w changes with the temperature of domestic hot water, and the average value is 3.39. In winter, the machine can carry out heating function and domestic hot water supplying function at the same time, but the temperature of domestic hot water should be set at reasonable value. In spring and autumn, the average COPa＋w, is about 1.25.
