摘要
水环热泵空调系统是小型水/空气热泵机组的一种应用。通过连通建筑物周边区和内区的水循环环路将小型水/空气热泵机组并联在一起,形成一个封闭环路,将建筑物内区制冷产生的冷凝热转移到周边区,作为周边区热泵的低温热源。水环热泵空调系统在对建筑物内区供冷的同时实现对周边区供热,使建筑物空调的内、外区冷热相抵,建筑物内部余热得到充分利用,节约了能源。本文比较了水环热泵系统相对于常规空调系统在系统结构、节省能源等方面的优势和应用中遇到的问题,并结合工程应用实例,分析了水环热泵空调系统的经济性。
In the water-circle heat pump air-conditioning system, the condensation heat produced by the small water/air heat pump units inside the district is transferred to the outskirt as the low temperature heat source of the small water/air heat pump units in the outskirt. At the same time of the inside district getting refrigeration the water circle heat pump air-conditioning system supplies heat for the outskirt. It makes the excess heat of the inside district get used and much energy will be saved. In this paper, the advantage on the sides of system configuration, energy saving etc. compared with the general heat pump air-conditioning system is introduced, and the problems of the system in application are also put forward. Combined with a practical application example, the economical efficiency of the water-circle heat pump air-conditioning system is discussed.
