摘要
对于以冷负荷为主导的建筑,采用冷却塔辅助散热复合式地源热泵一方面能调节地下散热的平衡,另一方面减少了系统的初投资,但同时增加了冷却塔水泵和风机的功耗。文中从地源热泵的动态模型入手,模拟了不同冷却塔容量选型时系统能耗情况。模拟结果表明,合理的冷却塔选型具有较大的节能潜力。
For cooling load-oriented architecture, the use of cooling tower in ground-source heat pump air conditioning system can not only adjust the thermal balance of the underground, but also reduce the system＇s initial investment. On the contrary, it increases the pump and cooling tower＇s power consumption. The system energy consumption for different cooling tower capacity selection based on the thermal dynamic model of hybrid ground-source heat pump system was simulated. The results show that there is an obvious energy-saving potential for a reasonable selections of cooling tower capacity.
