摘要
Abstract
The defrosting time, discharge pressure, indoor temperature fluctuations and other defrosting characteristics of air source
heat pump were experimentally investigated at three defrosting modes, i.e., reverse cycle defrosting, hot gas bypass defrosting and
phase change material defrosting. The results showed that the performance of phase change material defrosting system is better than
the others. The phase change material has increased the discharge temperature and the condensing temperature, which benefits to the
decrease of defrost time and energy consumption, and the indoor temperature is relatively stable.关键词
