摘　　要：大温差设计对于暖通空调设计及应用中的节能部分具有非常重要的意义。针对空调水系统大温差设计的特点及造成冷水机组效率降低的不良后果,在理论分析的基础上,通过公式推导计算,对冷水机组部分进行了分析,得到了合理的冷冻水温差与冷冻水供水温度之间的对应关系,从而为大温差设计在国内的应用及实践提供借鉴和参考。The chilled water system with large temperature difference is very important for HVAC design and application of energy-saving section.In accordance with the design features in AC water system with a large temperature difference and the adverse consequences of reducing the water chiller efficiency,the chiller of the system is analyzed by the formula derivation and calculation with theoretical analysis.The corresponding relationship between the chilled water temperature difference and the chilled water supply temperature is obtained as the reference for AC water system with large temperature difference in the domestic application and practice.
