| 摘 要： | 以具有间歇负荷特征的上海某科研办公楼为研究对象,对其冷却塔辅助冷却地埋管系统进行分析。计算建筑冷负荷和地埋管的放热量,7月份为一年中热泵系统运行最不利的时间段,针对地埋管单独运行和冷却塔辅助冷却2种方式,对比地埋管出口水温及热泵机组的EER。结果显示,该科研办公楼采用冷却塔辅助冷却方式后,地埋管出口水温明显降低,热泵机组的运行效率明显提升。

| Abstract: | A study is conducted on a ground source heat pump system with cooling tower used in one scientific research building with the intermittent load in Shanghai.Data is collected in July,the worst circumstances in a year.The building＇s cooling load and ground heat exchanger＇s heat release are calculated based on collected data.Through comparing the outlet temperature of ground heat exchanger and EERof heat pump system with and without cooling tower as a supplemental heat rejecter,the following results are gotten：with the auxiliary cooling,the outlet temperature of the ground heat exchangers becomes lower and the EERincreases significantly. |
