以南京某复合式地源热泵系统为研究对象，通过能耗模拟软件E nergyplus分析其天棚辐射空调系统的能耗，计算出地埋管侧全年累计散热量与取热量之比为3.97：1。该项目采用复合式的地源热泵系统，本文分析辅助散热设备运行控制策略以保证地源热泵系统可持续高效运行。比较三种控制策略得出：温差控制不适合散热量与取热量严重失衡的系统，因其控制温差不易确定，辅助散热设备启停频繁，且难以保证系统多年运行地下热平衡；热泵进口水温控制是保证地下热平衡的有效措施，但是需要选择合理的控制参数值，辅助散热设备启动较频繁；定时开启控制不仅能够保证系统持续高效运行，而且控制策略易于实施。

A Hybrid Ground Source HeatPum p system (HGSHPs)in Nanjing isresearched.The all-energy analysis sim ulation softw are E nergyplus is used to analyze ceiling radiation air conditioning system energy perform ance. B y analyzing the energy sim ulation results, the ratio of the heat dissipation and absorption to the ground by the ground source heatexchanger is 3.97:1 in one year.So auxiliary cooling equipm entis used and this paper tries to find the right control strategy and param eters to ensure system sustainable and operated w ith high efficiency. T hree control strategies forHGSHPssustainable operation are com pared.The resultsshow that:controlled by tem perature difference doesnot suitfor heatbalance control,for the tem perature difference is difficultto determ ine,and the auxiliary cooling equipm ent starts and stops frequently;controlled by the heat pum p inlet w ater tem perature insure the heat balance, but reasonable controlparam eters is im portant;controlled by open tim ing can notonly m ake sure the heatbalance,itcan m ake sure the H G SH Ps operated w ith high efficiency.
