地表水源热泵在地铁空调系统中的应用分析

Surface Water Heat Pump in Subway Air-Conditioning System

通过对地铁空调系统中应用地表水源热泵的能耗分析、环境评价及经济型分析,并结合南昌地铁一号线进行实例计算,得出采用地表水源热泵相对于采用常规冷却塔而言,冷却水系统节约电能30%以上,可减少对地铁车站周边的环境影响且降低运营成本,具有显著的社会效益和经济效益,为部分在建地铁的城市提供参考。

By the energy consumption analysis,environmental assessment and economic analysis of the surface water heat pump which applied in subway air-conditioning system,with the calculation in Nanchang subway lineⅠ,it concludes that using surface water source heat pump relative to the conventional cooling tower,more than 30% energy of the cooling water system is saved and the environmental impact around the subway station is decreased and operating costs are reduced.It has significant social and economic benefits,and will provide a reference to part of the cities which are building subway.
