土壤源热泵在合肥地区规模化应用绩效研究

Performance research on the large scale application of ground coupled heat pump system in Hefei

介绍了土壤源热泵的工作原理,探讨了土壤源热泵空调应用于中央空调系统的设计方法,以及其主要部件地热换热器的埋管方式、结构、管材、运行等特点。选取几种常用的冷热源系统与土壤源热泵系统进行比较,参考合肥地区的能源价格,计算各方案的运行成本,用动态费用年值法评价了各方案的经济性。最后,对土壤源热泵系统的节能减排量进行了分析。

The work principle of ground coupled heat pump（GCHP） was described and its design method used as the cen tral air conditioning system was discussed. The burying way, structure, tube material ans operation of soil heat exchanger as a main part of the system were introduced . The paper chose several kinds of commonly used cold source and heat source systems and carried on comparative analysis with ground coupled heat pump system. According to the energy price in Hefei, the operat ing expenses of every project were obtained, and economic evaluation of every project was carried out with annual cost approach. In the end, the paper analyzed the energy saving and emission of GCHP.
