In the latter case, pump consumption during hot water recirculation makes the overall system less efficient. Due to lower over-sizing factor, the centralized installation is more favourable to the ASHP performance than individual ones. In both the two cases, GHG emissions can be significantly ...
heat pump water heater breadboard facility was built and a performance evaluation was conducted to investigate the effect of ambient temperature and hot water temperature on the overall coefficient of performance (COP) during full tank heating tests in three scenarios typical of residential water ...

申请(专利权)人: WATERFURNACE INTERNATIONAL, INC. 发明人: RR Brown 被引量: 6 摘要: A hot water heat pump is coupled to a primary liquid heat source, typically an earth coupled closed loop system, and a hot water retention tank. The hot water heat pump extracts heat from the liquid ...
Frost build-up blocks the gap between fins and decreases the airflow rate, and the heating capacity and COP of air-source heat pump become lower. The reverse-cycle defrosting (RCD) and hot-gas bypass defrosting HGBD are the two common methods of frost removal. The comparison between the RC...
