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。
Aiming at the problem of energy waste caused by the traditional start-stop control mode of composite ground source heat pump, the energy consumption equation of the composite ground source heat pump system is established from the point of view of load distribution optimization, and the equations are solved by sequential weighting factor method, Cooling tower and ground source heat pump load distribution optimization. Through TRNSYS on the basis of the rated power distribution and load distribution optimization simulation, compared with two different distribution system COP. The results show that the system based on load distribution optimization is more efficient and saves energy.
