污水源热泵供热系统实际运行工况分析

Operating Performance Analysis on Heating System of Sewage Source Heat Pumps

以哈尔滨市应用的某污水源热泵为例,通过应用实际测试的方法,分析了污水热能利用情况及系统供热过程中热泵机组的供热性能。结果表明:在测试期间,室内外温差很大的情况下,污水源热泵仍能满足供热要求,具有良好的稳定性。热泵机组的平均供热性能系数为2.92。

Taking the sewage source heat pump applied in Harbin as an example, the utilization of sewage energy and the heating performance of heat pump unit during the system heating progress was analyzed by the actual test way. The results show that, at the test period and under the condition of large difference between indoor temperature and outdoor temperature, the sewage source heat pump still satisfy the heating quest and have a good stability. The average heating performance of the heat pump unit is 2.92.
