| 摘 要： | 在夏热冬暖或夏热冬冷地区使用地源热泵时,往往存在热积累效应,导致系统性能下降。本文以上海某宾馆建筑为例,从短期运行及长期运行2个方面,通过比较采用冷却塔前后地埋管换热系统进出口水温及和热泵机组COP变化,研究冷却塔辅助冷却地埋管换热系统在连续负荷建筑中的应用。研究得出在该宾馆建筑中使用冷却塔辅助冷却地埋管换热系统能够很好地解决热积累问题,而且能保证较高的机组性能。

| Abstract: | When ground-source heat pump （GSHP） system runs in hot-summer and warm-winter zone or hot-summer and cold-winter zone,heat accumulation effect often oc curs,which leads to lower performance. Taking a hotel building in Shanghai as an example,inlet ＆ outlet water temperature and COP of GSHP before and after using cooling tower are compared from two aspects of short-term and long-term operation, to research the application of buried pipe heat-exchange system with cooling tower auxiliary into the continuous load type buildings. It is concluded that heat accumulation effect can be effectively solved and higher COP can be obtained by using buried pipe heat-exchange system with cooling tower auxiliary in this hotel building. |
