摘　　要：以配置冷却塔的复合式土壤源热泵为研究对象,建立了地埋管换热器简化计算模型。分析了地埋管换热器管内水流量、进水温度、土壤初始温度、地埋管连接形式对其性能的影响。探讨了地埋管换热器与冷却塔的联合工作特性。Taking the hybrid ground source heat pump with cooling tower as research object, a simplified calculation model of buried tube heat exchanger is established. The influence of water flow in buried tube heat exchanger, inlet temperature, initial soil temperature and connection mode of buried tubes on its performance is analyzed. The conjoint operation characteristics of buried tube heat exchanger and cooling tower are discussed.
