重庆某医疗建筑冷却塔复合式地埋管地源热泵系统设计

Hybrid ground-source heat pump system design of a hospital building in Chongqing

以重庆市某医疗建筑为例,基于动态负荷模拟,介绍了地埋管地源热泵系统设计时需重点考虑的全年土壤换热平衡问题。总结了当建筑的冬夏冷热负荷差异较大时,按照冬季热负荷设计地埋管系统,夏季将冷却塔作为辅助冷源进行地埋管设计和冷却塔选型的方案,并探讨了基于以上设计思路的冷热源节能运行方案。

Taking a hospital in Chongqing as an example,based on the dynamic load simulation, presents that the annual thermal balance of underground soil is the key problem in hybrid ground-source heat pump system design.In view of cooling and heating load difference between summer and winter, summarizes the ground-source heat pump system design scheme which designs the ground heat exchanger based on winter heating load,and the cooling tower as an auxiliary in summer.Discusses the heat and cold sources energy-saving operation programs based on the above design ideas.
