重庆地区地表水地源热泵系统冬季供暖工程应用

摘要

Tests the heating operating conditions of five surface water source heat pump projects in Chongqing area,and compares them with those of the air source heat pump and boiler heating mode.The results show that the heating coefficient of performance (COP) of the river water source heat pump unit reaches 2.8 to 5.3 and the heating energy efficiency ratio (EER) reaches 2.7 to 4.3,and the COP and EER of the lake water source heat pump system reach 4.4 and 3.0 respectively; the indoor temperature and relative humidity can be maintained about 20℃ and above 40％ respectively; the improving rates in energy efficiency of a surface water source heat pump system for winter heating are respectively 8.0％ to 72.0％and 18.0％ to 87.9％ compared with the air source heat pump and boiler heating,and energy saving is significant.%以重庆地区5个地表水地源热泵项目为例,对其冬季供暖运行工况进行了实测,并与空气源热泵和锅炉供暖进行了比较.结果表明,江水源热泵系统的机组制热性能系数COP和系统制热能效比EER分别能达到2.8～5.3和2.7～4.3,湖水源热泵系统的COP和EER分别能达到4.4和3.0,并且室内温度和相对湿度分别能保持在20℃左右和40％以上；相比于空气源热泵和锅炉供暖,地表水地源热泵系统冬季供暖的能效提高率分别达到了8.0％～72.0％和18.0％～87.9％,节能显著.
