【摘要】 地源热泵系统由于增加了地热换热器而使系统的投资增加,随着系统连续运行时间的增加,系统效率也随之下降。对以冷负荷为主的地区,当冷热负荷的比率超过2时,采用辅助散热设备后,系统的效率提高,同时系统的总投资也减少。当地热换热器出口水温超过当地土壤温度20℃时,可启动辅助散热设备运行。更多还原

【Abstract】 The cost of the ground-coupled heat pump system raises because of the increase of the geothermal exchanger and its efficiency will decrease with the operating time.Where the cooling load is dominant,when the supplemental heat rejected facility is utilized,the system efficiency improves and the cost decreases on condition that the ratio of cooling load to heat-ing load is more than two.更多还原
