摘　　要：以天津地区为例,通过模拟用户24 h供热水和供暖情况,研究空气源热泵在冬季频繁除霜工况下供热水和采暖的运行特性,分析供热水和采暖性能间的相互影响。非除霜时段,热泵制热量受供热水影响缓慢下降;供暖的同时大容量供热水,热泵制热量剧烈上下波动;供暖、供热水与除霜运行相重合时,除霜对热泵制热量影响占主导;系统实际供暖负荷受对外供热水情况影响显著。By simulating hot water supply and space heating during 24 h in Tianjin, the operation performance of air source heat pump under frequent defrosting was studied, and interaction of the two performances was analyzed. In nondefrosting period,heat production of heat pump had a slow decline during hot water discharge;heat production can be fluctuated violently during hot water discharge with space heating;when space heating, water discharge and defrosting co. incided, the effect of defrosting was dominant;and the actual heating load of heat pump was significantly affected by hot water discharge.
