摘要
针对由于空调建筑全年所需的冷量和热量的不均衡性,使得土壤的年吸、释热量不平衡,从而将导致系统在连续多年运行后,热泵机组的运行效率不断下降,甚至会出现停机现象,该文以北京地区某一建筑的土壤源热泵系统为例,提出了增加辅助散热设备一冷却塔的设计方法,并利用 TRNSYS 模拟软件对冷却塔与埋管换热器的不同连接方式,即串联和并联,进行了模拟计算,得出了可保证土壤源热泵系统长期高效运行的各种设计方案,为在寒冷地区正确设计土壤源热泵系统提供了具体的解决办法。
Due to the different heating and cooling load of a building, the imbalance between the annual heat absorption from the ground and heat release to the ground usually exists, and this will make the heat pump＇s efficiency deteriorate consistently, even to the break down of the heat pump. It puts forward a design method of adding supplemental heat rejection equipment-cooling tower-in the system to solve the problem in cold area. Taking an office building in Beijing as an example, the authors simulate GSHP systems with two different connection methods between the cooling tower and the vertical buffed-pipe heat exchangers （in series and in parallel） using TRNSYS simulation software, and finds out several design schemes that can ensure the whole system to operate with high efficiency continuously, and thus provides concrete solutions for the correct design of a GSHP based system.
