地源热泵与冰蓄冷耦合系统的设计与实现

介绍了地源热泵蓄能系统的结构组成,包括地源热泵技术与冰蓄冷技术,分析了两者的技术优缺点,进而讲述了两者联合运行的必要性.在此基础上设计建立了一个生态节能的空调系统,首先对地下埋管的深度及距离的取值进行了分析,并阐述了该系统的运行控制策略和流程,实现了机组在常规空调工况、制冰工况以及供暖工况三者之间的调节.最后,对该系统进行了经济性分析,在运行费用上,比传统空调系统节省69%,具有显著的节能优势.

Design and implementation of ground source heat pumps combined with ice thermal storage systems

The structure of ground source heat pump energy storage systems is introduced.that indudes the ground source heat pump technology and the ice thermal storage technology.The technical advantages and disadvantages of both were analyzed.Therefore a joint operation was necessary.Then an ecological air conditioning system was designed;and the depth of buried pipes and the distance between the pipes were analyzed.An operating control strategy was expatiated which included the regulation and workflow among the three working conditions-conventional air conditioning,ice making condition and heating condition.In the end,the economic viability of such a system was evaluated.It was found that under the same condition this system would save 69 % operating cost of a traditional air conditioning system.Obviously,it has a remarkable energy saving adnantage by using the ground source heat pump with energy storage.
