摘　　要：在低环境温度工况下,分别对定频、普通变频空气源垫泵机组以及带有补气增焓功能的变频空气源热泵机组的性能进行试验。结果表明:变频空气源热泵机组的IPLV明显优于定频空气源热泵机组,且带有补气增焓功能的变频空气源热泵机组在环境温度低于-20℃时比定频、普通变频空气源热泵机组的制热量衰减小,制热效果较优。The performance tests on the constant frequency air source heat pump, the traditional frequency-conversion air source heat pump and the frequency-conversion air source heat pump with refilling and enthalpy increasing device （REID） are conducted under the low ambient temperature condition. The results show that the IPLV of the frequency-conversion air source heat pump unit is obviously better than that of the constant frequency air source heat pump unit. The attenuation of heating capacity of frequency-conversion air source heat pump unit with REID is smaller than that of the constant frequency and the traditional frequency-conversion ones at below - 20 ℃, which has better heating performance.
