现场安装的热泵系统的基本部件包括制冷压缩机、在不需要储存时将多余热量散发到大气中的冷却器、埋地保温储水箱、冷冻水和冷凝水循环泵、加热和冷却盘管以及用于加热的应急备用锅炉。必须提供自动温度控制系统，采用三通旁通阀或分流阀、热传感器、限位控制器和恒温器。三种类型的压缩机可用于热泵系统的构造——往复式压缩机、离心式压缩机或螺杆式压缩机。从历史上看，往复式压缩机的维护成本高于离心式压缩机，而三级离心式压缩机利用130°F（54°F）的运行成本更高。 4°C）单级或两级离心机上的冷凝水温度可节省105°F（40.6°C）的冷凝水温度。引文:新墨西哥州阿尔伯克基市阿什雷学报第84卷第2部分

The basic components of a field erected heat pump system consist of a refrigeration compressor, a cooler to dissipate unwanted heat to the atmosphere when not required for storage, buried insulated water storage tank, chilled water and condenser water circulating pumps, heating and cooling coils and an emergency back-up boiler for heating. An automatic temperature control system must be provided employing three-way by-pass or diverting valves, heat sensors, limit controls and thermostatsThree types of compressors can be used for the construction of a heat pump system -- a reciprocating compressor, a centrifugal compressor or a screw type compressor. Historically, maintenance costs have been higher for reciprocating type compressors than for centrifugal compressors, while three stage centrifugal compressors have a higher KW per Ton operating cost utilizing 130°F (54.4°C) condensing water temperatures over single or two stage centrifugal machines saving 105°F (40.6°C) condensing water temperature.
