为了探讨上海地区小型竖直埋管地源热泵空调系统的性能及其适用性,笔者建立了一小型竖直埋管地源热泵空调系统实验台。本文分别在上海典型供冷工况和供热工况下,对该系统地埋管换热器的进出口水温、换热能力及热泵机组的性能进行了实验和分析。所得结果可为上海地区竖直埋管地源热泵空调系统的工程设计和理论研究提供参考。
In order to investigate the performance and applicability of the small vertical buried geothermal heat pump air conditioning system in Shanghai, a small vertical buried geothermal heat pump air conditioning system bench was established. In this paper, the inlet and outlet water temperature, heat exchange capacity and the performance of heat pump units of underground heat exchangers in the system are respectively tested and analyzed under typical cooling and heating conditions in Shanghai. The results can provide reference for engineering design and theoretical research of vertical buried geothermal heat pump air conditioning system in Shanghai.
