摘要
在分析南京某印刷厂房地源热泵中央空调系统的运行实测数据的基础上,探究了地源热泵系统运行对地埋管周围土壤温度场的影响;比较了系统供冷/供热运行对土壤温度的影响程度,分析了室内负荷变化对系统运行状态的影响;对于冷热负荷不均的地区,针对设置辅助散热设备的关键性,提出地源热泵中央空调系统的高效运行策略和在系统设计过程中应该注意的问题,以期为类似工程项目运行管理提供相关经验和依据。
Based on the analysis of the operation of the ground source heat pump central air conditioning system of a printing plant in Nanjing,this paper explored the influence of the GSHP buried pipe on the soil temperature field,compared the effect of cooling/heating system running on the soil temperature,analyzed the impact of indoor load changing to the system for cold and hot load.For the regions with uneven heating and cooling loads,aiming at the key points of setting auxiliary cooling equipment,the efficient operation strategy of GSHP central air conditioning system and the problems that should be focused to in the process of system design are proposed in order to provide relevant experience for the operation management of similar project.
