摘　　要：按照《全国民用建筑工程设计技术措施(2009)暖通空调·动力》提供的计算方法得出的双工况冷水机组标定制冷量,不能满足冰蓄冷空调系统的实际工程使用要求。针对该问题,本文结合实际工程案例,通过增大双工况冷水机组标定制冷量或延长白天空调工况运行时间的方式,比较不同方案的运行控制策略、初投资和运行费用,得到双工况冷水机组的选型方法及最佳蓄冰率。The calibrated cooling capacity of the double working condition water chiller calculated by the formula,based on National Technical Measures for Design of Civil Construction-Heating,Ventilation and Air Conditioning(2009),can not meet the actual requirements of the ice storage air-conditioning system.In order to solve this problem,combined with the actual project,by increasing the calibrated cooling capacity or daytime operation time of the double working condition water chiller,the operation control strategy,initial investment and operation cost of different schemes are analyzed and compared,and the selection method and optimal ice storage rate of the double working condition water chiller are obtained.
