Abstract

Based on the study of the mechanism of defrosting of air-source heat pump (ASHP), a novel non-frosting air-source heat pump (NASHP) and its test rig were developed. The NASHP system has been proved feasible by the experiment. When it ran in "frost prevention" mode, its temperature difference of air was 1.5°C larger and its heat output was 6% higher than that of conventional system. Moreover, for the compression ratio and parameters of air almost kept the same in the running process, the compressor and system was stable. When the glycerol was selected as spray solution for NASHP, for ensuring the effect of frost prevention, glycerol content should be 31%-65% (mass) and its flow of unit windward area should be 0.53-0.64 t·(h·m²)^-1.
