摘要
在上海地区完成了五种运行模式下太阳能-地源热泵联合运行供暖试验,分析比较不同模式系统运行特性,确定并联模式下上海地区居住建筑太阳能-地源热泵复合系统的较佳流量配比以及串联模式下的最佳串联方式。试验结果表明:并联运行模式中蒸发器出口流体进入蓄热水箱和地埋管的比例为1:1时为较佳运行模式,此模式下平均系统COP和运行结束时平均土壤温降分别为2.19和3.01℃;串联模式1的系统运行特性优于串联模式2,运行周期内串联模式1的系统COP和运行结束时平均土壤温降分别为2.12和3.33℃。
The heating tests of solar-ground source heat pump system with five operation modes were conducted in Shanghai. The system operation characteristics of different modes were analyzed and compared,then the better flow proportioning of combined solar-ground source heat pump system for residential buildings in Shanghai region under parallel mode and the best series connection method under series mode were determined. The test results show that when the proportion of fluid at the evaporator outlet in the parallel operation mode entering the heat storage water tank and the buried pipe was 1:1,the operation mode was better,and the average system COP and the average soil temperature drop at the end of running under this operation mode were2.19 and 3.01 ℃,respectively. The system operating characteristics in series mode 1 were better than those in series mode,and the average system COP and the average soil temperature drop at the end of running were 2.12 and 3.33 ℃,respectively.
