住宅建筑热泵的热源选择

摘要

Statistics show that residential building HVAC energy consumption accounts for a great proportion in building energy consumption. Heat pump has better energy conservation performance compared with coal--fired heating. The characteristics of residential building HVAC energy consumption are relative concentration of space and time, a smaller amount of heat demand, stable and high security requirements, easy maintenance and management. The selection of heat sources of the pump should meet the heating and cooling requirements of residential building and pump system. This paper investigates the heat sources of air, ground/underground water, soil, sunlight, sewage from the aspects of characteristics, applicability, limitation, engineering and equipments, and management. Finally, it concludes the general principles in selecting the heat sources of heat pump for residential building.%指出了住宅建筑的暖通空调能耗占建筑能耗的比重大，较燃煤取暖而言，热泵技术的节能效果显著。从原理特点、适用性、限制条件、土建和设备建设难度和周期、后期管理维护等方面分析了空气、地表（下）水、土壤、太阳能和污水等热泵热源，探讨了住宅建筑热泵热源选择的总的原则。
