住宅建筑地源热泵系统冷热源方案对比分析

Comparative analysis of cold and heat source schemes for ground-source heat pump systems in residential buildings

目前,在国家大力推进环境保护和实施节能降耗的相关政策后,地源热泵的发展具有很大的发展潜力。地源热泵是一种利用浅层地热能源的既可供热又可制冷的高效节能系统,它既可以增加能源的使用效率,又可以减少环境污染,节约能源费用,以此达到节能减排、绿色环保的目的。将地下水源热泵技术用于建筑施工,能够适应冬季采暖、夏季制冷的需要。如果采用地源热泵+冷冻机+城市管网供暖的混合系统作为主要的住宅建筑提供冷热源,可以充分发挥地埋管道的高热效率,从而使地埋管换热器只承担建筑物的基本冷热负载,而高于基本负载的峰值冷热负荷则可以通过冷却塔和供暖系统来完成,确保供热供暖的高效。

At present,the development of ground-source heat pump has great potential for development after the state vigorously promotes environmental protection and the implementation of energy saving and consumption reduction policies.Ground-source heat pump is a kind of high-efficiency energy-saving system which can supply heat and refrigerate by using shallow geothermal energy,in order to achieve energy-saving emission reduction,green environmental protection purposes.The application of underground water source heat pump technology in building construction can meet the needs of winter heating and summer refrigeration.If the mixed system of ground-source heat pump+refrigerator+urban pipe network heating is used as the main residential building to provide heat and cold source,it can give full play to the high thermal efficiency of the buried pipe,so that the buried pipe heat exchanger only assumes the basic heat and cold load of the building,and the peak heat and cold load higher than the basic load can be completed through the cooling tower and heating system,to ensure the high efficiency of heating and heating.
