【摘要】 针对在我国“三北”地区应用热泵供暖所普遍存在的困难和问题 ,简要介绍了一种能在寒冷地区实现“生态循环供暖”的新型热泵供暖系统 ,即空气 /水和水 /空气双级耦合热泵系统 ;然后指出了其在应用中存在的问题 ,即在能够满足空气源热泵单级运行条件的供暖季大部分时间内 ,系统仍然需要双级耦合运行 ,从而使得系统的供热能效比 (EER)和季节供热性能系数 (HSPF)大为降低 ;最后 ,针对这种系统作了改进 ,提出了一种单、双级混合式热泵供暖系统 ,使问题得到解决 ,同时 ,还对两种系统的季节供热性能系数 (HSPF)进行了比较。更多还原

【Abstract】 Aimed at the problems of broadly using air-source heat pump in the "sanbei"regions,theis article briefly introduce a new kind of heat pump heating system-the air-to-water and water-to-air twin coupling heat pump heating system,which could realize zoology-circulation heating;then point out the problems in practical application,namely in the mostly time single stage air-source heat pump could work properly,the new heating system has to work in twin stages,leading to great declination of EER and HSPF of the system;finally,bring out some improvement measures,put forward a mixture of single-twin stages heat pump heating system and solve the problem.What is more,compare the HSPF of the two heating system.更多还原
