摘要
冷却塔复合式地源热泵空调系统能有效调节地下土壤的热平衡,提高系统的运行效率,同时也可以减少系统的初投资。复合式地源热泵空调系统额外增加了板式换热器、冷却塔、冷却塔循环水泵等,整个系统的运行特性也有了很大的改变。本文基于整个系统的动态运行特性,建立了各个部件的动态模型,并对整个系统的运行做了动态模拟。模拟结果表明,冷却塔及水泵功耗在复合式地源热泵系统具有较大比例。
Cooling tower hybrid ground-source heat pump air conditioning system can not only adjust the thermal balance of the underground to improve the operational efficiency but also reduce the system＇s initial investment.It adds extra plate heat exchangers,cooling towers and cooling tower circulating water pump,and the operating characteristics of the system are changed greatly.The models of the parts were established base on the dynamic operating characteristics.
