摘　　要：为了挖掘影响空气源热泵系统供热性能的主要参数,该研究通过在住户客厅中布置温度测点,同时在供热系统供回水干管处布置温度、流量监测点进行相关数据监测,对郑州某空气源热泵供热项目的性能进行实测分析。测试结果表明,空气源热泵系统中热泵机组占热泵系统总能耗的比重较大,从节能的角度,可以选用能效较高的空气源热泵机组来降低运行成本。针对循环水泵的节能降耗,可以采用自动变频技术根据供回水温差调节循环水泵的运行频率。To explore main parameters that affect the performance of the air source heat pump heating system,the heating performance of an air source heat pump heating project in Zhengzhou was measured and analyzed by setting the temperature measure points in the living room and temperature and flow measure points on the main supply and return water pipes.The test results show that energy consumptions of heat pump units account for a large proportion of the total the air source heat pump heating energy consumption.From the perspective of energy conservation,the air source heat pump units with higher energy efficiency can be selected to reduce the operation cost.Meanwhile,for the energy saving of the circulating pump,automatic frequency conversion technology can be used to adjust the operating frequency of the circulating pump according to the tempera-ture difference between the supply and return water.
