摘要
采用辅助供热复合地源热泵系统,可有效降低系统初投资,提高系统的节能效果。本文以哈尔滨地区某客站为计算对象,数值模拟得到地埋管冬季先运行和夏季先运行两种工况下的土壤全年温度变化,分析比较了严寒地区锅炉复合地源热泵系统在不同的负荷分担比例下的节能性和经济性,分别给出了两种工况下的地源热泵合理的设计负荷分配比例,并分析了锅炉种类、钻井费用、天然气价格和运行年限对锅炉复合地源热泵系统合理负荷分担率的影响,为相关工程实例提供参考。
The initial investment and enhance the efficient of energy-saving will be reduced by using assistant heating composite ground source heat pump system.Having gotten the annual temperature of ground heat exchanger first run in winter and summer through numerical simulation,this paper analyzed the energy-saving and economy on boiler-ground source heat pump systems with different heating load ratios in Harbin.Two optimal heating load ratios for this kind of structure have been presented.At last,the influencing factors such as the species of boilers,price of drilling,natural gas and life of system for boiler-ground source heat pump system have been also analyzed.It will give a great forceful reference for the future projects.
