摘　　要：本文搭建了带闪发补气的家用空气源热泵热水器实验系统,在环境控制室中研究其在不同温度下的运行性能,并与单级压缩系统进行对比。结果表明:带闪发补气的家用空气源热泵热水器制热量和制热COP均大于单级压缩系统,环境温度为-15℃时,制热量增大21.3%;相同水量和初始、结束温度下,补气系统的加热时间较单级系统缩短20.1%;闪发补气使压缩机的排气温度降低11.3℃,保证了机组的运行安全;APF计算表明闪发补气的系统在环境温度较低地区使用效果更好。The experimental system of household air-source heat pump water heater with flash tank was set up,and its operation performance at different temperatures was studied in the environmental control room,and compared with the single-stage compression system.The results show that the heating capacity and heating COP of the household air-source heat pump water heater with flash tank are greater than that of the single-stage compression system,and the heating capacity increases 21.3%when the ambient temperature is-15℃.The heating time of air-source heat pump water heater with flash tank system is shortened by 20.1%compared with that of single-stage system under the same water volume and initial and ending temperatures.The discharge temperature of the compressor is reduced by 11.3℃,which ensures the operation safety of the unit.The calculation of APF shows that the system of flash tank replenishment is better in the area with lower ambient temperature.
