摘　　要：针对目前空气源热泵热水器存在的问题,建立了以制冷剂R134A为工质的实验台进行实验研究,在不同的环境温度、供水温度的不同、制冷剂的种类、制冷剂流量的大小、制冷剂的充注量的多少、换热器和压缩机及节流装置等因素影响下得出数据。通过分析空气源热泵的工作原理和实验装置,提出了提高空气源热泵热水器性能的优化措施,为设计高效热泵热水器提供了可供参考的实验数据。Based on th current problems for air source heat pump water heater, a test table used R134A as refrigerant was established. The experimental data were obtained under the influences of such factors as ambient temperature, water temperature, kind of refrigerant, refrigerant flow rate, the charge of refrigerant, heat exchanger, compressor and the throttle device. Through the study of the working principle for air source heat pump and the achievement of experimental setup, the measurements to improve the performances of air source heat pump were proposed.
