摘　　要：以湖南地区某综合楼的复合式地源热泵系统为研究对象,分析了该建筑的负荷特征及生活热水的需求特征。为保证地源热泵高效稳定运行的同时,还需减缓或避免地热不平衡率。提出了一种“热水地埋管+地源热泵地埋管+冷却塔”三者为一体的“三联控”的新复合式地源热泵系统的控制策略。通过这种“三联控”控制策略,降低由于冬夏季负荷不平衡所引起的“热堆积”现象,使地源热泵系统的效益最大化。This paper takes the compound ground source heat pump system of a complex building in Hunan province as the research object and analyzes the load characteristics of the building and the demand characteristics of domestic hot water.In order to ensure the efficient and stable operation of ground source heat pump,it is necessary to reduce or avoid the geothermal imbalance rate.This paper presents a control strategy for a new compound ground source heat pump system,which is composed of"hot water buried pipe+ground source heat pump buried pipe+cooling tower".Through this"triple control"control strategy,the phenomenon of"heat accumulation"caused by load imbalance in winter and summer is reduced,and the benefit of ground source heat pump system is maximized.
