对某机场地源热泵系统地埋管换热器的换热性能进行了测试,计算得出了热泵机组和系统的能效比,进而评价了整个空调工程在运行阶段的能效水平。重点介绍了测试台的搭建、低温测试的主要参数。
The heat exchange performance of the ground tube heat exchanger of a ground source heat pump system in an airport was tested. The energy efficiency ratio of the heat pump unit and the system was calculated, and the energy efficiency level of the whole air conditioning project in operation was also evaluated. The construction of test bench and the main parameters of low temperature test are introduced emphatically.
