静态加热式空气源热泵热水器运行性能的试验研究

Experimental study of operating performance on static air-source heat pump water heater

在焓差法空调器性能测试平台上,对静态加热式空气源热泵热水器的运行性能进行了试验研究.在环境温度为(20±1)℃,水箱水温从15℃升高到55℃的过程中,吸气压力和吸气温度无明显变化,排气压力和排气温度均升高,压缩比升高,电功率消耗增大,系统的平均性能系数约为4.76,节能效果明显.

The operating performance of air heat pump water heater with static heating was tested based on air conditioning measurement platform.At ambient temperature of（20±1）℃with water tank temperature from 15 ℃ to 55 ℃,the system parameters such as suction pressure and suction temperature had no significant change.Discharge pressure,discharge temperature,compression ratio and compressor input power all rose.The average COP was about 4.76,and the system showed feasibility in energy saving.
