Abstract

The performance factors of a R290 variable frequency heat pump water heater are experimentally studied. The performance factors including COP, heating time, consumption power , compression ratio, degree of super heat and degree of sub cooling with the frequencies changing from 40Hz to 90Hz are discussed. The results show different compressor frequency has a greater influence on the size of the heat, and heat increases with the increasing of the frequency.When the outlet water flow is increased, the heat capacity and COP are improved corresponding. In addition, the compression ratio, degree of superheat is direct ration with frequency, but the degree of subcooling is reverse with it.
