地源热泵与冰蓄冷联合运行空调系统经济性分析

摘要

结合实际工程,建立了能耗分析模型,计算了热泵机组的全年耗电量及全年运行费用.采用一次投资回收年限和寿命期内年度费用指标两种评价方法对不同冷热源方案进行了经济性比较,结果表明,地埋管地源热泵与冰蓄冷联合运行空调系统初投资回收年限适中,平均年运行费用最低.%With an engineering example, develops an energy consumption analysis mode, and calculates the annual power consumption and the annual operation cost. Compares from an economical angle different cold and heat source schemes with two evaluation methods of the payback period of investment and the average annual operating cost. The results show that the ground-source heat pump combined with ice storage air conditioning system has a moderate payback period of investment and the lowest average annual operation cost.
