摘　　要：系统整理了台湾各地的平均地温,重点研究冬季蓄能混合式地源热泵(STES-HyGCHP)系统在台湾办公类建筑中的运行策略与节能潜力。在夏季和过渡季节的部分时间用地埋管取代冷却水塔,在冬季通过冷却水塔和地埋管联合运行带走土壤积蓄的热量并储存"冷"能,可解决土壤热容失衡问题也可提高空调主机效率。经过eQuest模拟和全年逐时迭代计算,在台南应用混合式地源热泵系统,模拟案例的全年空调系统耗能最高可降低5.85%,利用尖峰和离峰电价差,可实现电费降低7.44%,在台北这两项数值分别为3.21%和4.71%,并证实该系统为具备可持续运行的能力。地下水流动的影响和经济性在文中并未涉及。This paper provides the average ground temperature in Taiwan, and focuses on the appli-cation potential of seasonal thermal energy storage-hybrid ground-coupled heat pump （STES-HyGCHP） in central air conditioning system of ojfice buildings. During most working hours in summer and some part in other seasons, the ground-coupled heat exchanger （GCHE） can replace the cooling tower to provide water with lower temperature to condenser. In winter, the cooling tower and GCHE can work together to take the accu-mulated heat out of the earth. According to the simulation of eQuest and calculation, STES-HyGCHP can realizes 5.85% reduction of energy consumption and electricity bill sewing of 7.44% due to the different electricity prices of peak and ojf-peak times in the simulated office buildings in Tainan, 3.21% and 4.71% respectively in Taipei. However the return on investment and the compact of underground water need farther study.
