伊春地区土壤源热泵系统运行测试分析

Operation Test and Analysis of a Ground-source Heat Pump System in Yichun

从2014年冬季到2015年夏季对黑龙江省伊春地区一土壤源热泵系统的运行情况进行了测试,通过对测试结果的分析,获得了热泵系统夏、冬季工况下用户侧和地埋管侧的供、回水以及机组与系统的性能系数的温度变化规律。测试结果表明,由于建筑夏季冷负荷远小于冬季热负荷,因此热泵系统冬季性能优于夏季。

Operation tests of a ground-source heat pump system in Yi Chun were conducted from the winter of 2014 to the summer of 2015. Supply and return water temperature of user-side and ground side, the coefficient of performance of the heat pump unit, and the coefficient of performance of the heat pump system under summer and winter operation conditions were obtained based on the analysis of the testing results. Testing results show that the performance of the heat pump system under summer operation condition is better than that in winter operation condition due to the fact that cooling load of the building is much smaller than the heating load.
