| Abstract: | In this paper, the effect of-12 ℃ ambient temperature and frosting of external heat exchanger on the performance of heat pump system is experimentally studied, and effective defrosting strategy is proposed to ensure the safe and stable operation of the system. By adopting effective and reasonable defrosting strategy, the time of frosting can be reduced, and the effect of frosting on system performance can be greatly reduced. |
