沈阳地区地下水地源热泵与锅炉房联合供热的配比研究

Study of allocation proportion for combined heat-supply system based on groundwater source heat pump and boiler plant in Shenyang area

以沈阳市某小区的地下水地源热泵与燃煤锅炉房联合供热系统为研究对象,结合热负荷延续时间图进行了能耗分析,采用费用年值法进行了经济性分析,获得了两种热源联合供热的最佳分配比例。结果表明,辅助系数为0.46时,地下水地源热泵与燃煤锅炉联合供热系统的费用年值最低,节能效果较好,该种供热方式应在适宜地区推广。

Taking the combined heat-supply system of a residence community in Shenyang based on groundwater source heat pump and boiler plant as the research object, analyses the energy consumption combined with the heat load duration graph and performs the economic analysis with the annual cost method. Obtains the best allocation proportion of the combined heat-supply system. The results show that the annual cost of the combined heat-supply system is the lowest when the auxiliary coefficient is 0.46. Its energy saving perfrom_anceis very well. This kind of heating supply way should be introduced in suitable area.
