摘要
针对寒冷地区空气源热泵结霜问题,对一种新型空气源热泵进行实验测试和数据分析,结果表明在结霜较少时有助于提高热泵的制热量和cop,但随着霜层的不断增加,空气源热泵的COP和制热效果不断恶化.
Aiming at the problem of air source heat pump frosting in cold areas,a new air source heat pump was tested experimentally under frosting conditions.The results show that,with less frost,its heat capacity and COP can be improved,slow speed of frost.However,with the increasing of the frost layer,COP and the heating effect will be influenced greatly.
