摘　　要：利用冷水机组关机后冷水剩余冷量,次日提前开启空调系统对房间预冷,可提高房间使用时的舒适度、降低空调系统能耗。提出了冷水机组停机后任意时刻冷水温度的计算方法。结合工程实例,分析了预冷阶段冷水机运行模式,对空调系统提前开启时间进行了计算。Through starting air-conditioning system in advance on the next day, the utilization of residual cold energy fiom chilled water after shutting down water chilling unit for precooling room can im- prove the thermal comfort in room and reduce the energy consumption of air-conditioning system. A calculation method of chilled water temperature at any time after shutting down water chilling unit is presented. Taking an engineering case for example, the operation mode of water chilling unit in the precooling stage is analyzed, and the starting time of air-conditioning system in advance is calculated.
