Design of hybrid ground-source heat pump system for a hotel building in Ningbo
摘要：
分析了地埋管换热器的设计要素。综合考虑当地地质条件、地源热泵的优势以及冷热负荷的特点，设计了混合式地源热泵系统。采用地埋管换热器满足热负荷、辅助冷却装置补偿冷负荷的方案。热水系统采用闭式储水罐加地源热泵机组，与空调系统的地埋管换热器相间布置，夏季运行时形成了良好的互补性，解决了冬夏季土壤的热平衡问题，提高了机组的运行效率。
Abstract：
Analyses the key design elements of grourd heat exchangers. Taking account of the local geological condition, the advantages of the ground-source heat pump system and the condition that cooling load is higher than heating load in this area the building located, designs a hybrid ground-source heat pump system（HGSHPS）. The heating load is provided by the ground heat exchanger, and the cooling load is complemented by the auxiliary cooling device. The hot water system involves the unit of closed water storage tank plus ground-source heat pump. The ground heat exchangers of hot water system and air conditioning system are alternately arranged, which gains ideal complementary in summer, keeping the heat balance of ground and improving the operating efficiency.
