摘　　要：针对复合地源热泵传统启停控制方式造成能源浪费的问题,从负荷分配优化角度出发,建立了复合地源热泵系统的能耗方程,并利用序贯加权因子法对方程进行求解,进而实现对冷却塔和地源热泵的负荷优化分配。通过TRNSYS对按额定功率分配方式以及负荷优化分配方式进行模拟,对比两种不同分配方式下的系统COP。结果显示,利用基于负荷优化分配方式的复合地源热泵系统效率更高,节能效果明显。For the energy waste problem of the traditional start-stop control in composite GSHP (Ground Source Heat Pump) system, establishing the energy consumption equation of GSHP from the perspective of load distribution, and using sequential unconstrained minimization technique to get the solution of the equations in order to achieve optimal load distribution for cooling tower and ground source heat pump. Then building the model of composite GSHP system in TRNSYS so that the COP(Coefficient Of Performance) of the system can be simulated and compared under rated power distribution and optimal load distribution. The simulation results show that the cooling efficiency of composite GSHP system based on optimal load distribution is higher than the efficiency of traditional distribution, and having a better energy-saving performence.
