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 auxiliary heating compound ground source heat pump system can effectively reduce the initial investment of the system and improve the energy saving effect of the system. In this paper, a passenger station in Harbin as the calculation object, the numerical simulation of underground pipe running in winter and summer before the first two operating conditions of the soil temperature changes in the year, analysis and comparison of the boiler in the harsh area of the ground source heat pump system at different loads Share ratio of energy-saving and economy, respectively, under two conditions were given ground-source heat pump reasonable design load distribution ratio, and analyzed the type of boiler, drilling costs, natural gas prices and operating life of the boiler complex ground source heat pump The impact of reasonable load sharing system, provide a reference for the relevant engineering examples.
