空调水系统大温差设计是一种节能措施，了解大温差空调水系统的适应范围具有重要意义。本文基于某大型商场大温差空调冷水系统的设计，分别对冷水机组和冷冻水泵单位制冷量的能耗进行分析，结果表明该工程采用6℃/13℃的冷冻水供回水温度较常规7℃/12℃的供回水温度，单位制冷量制冷主机增加能耗0.0011kW，单位制冷量冷冻水泵减少能耗0.01kW，推算全年空调季两大耗能设备节省运行费用10.6万元。建议大温差冷冻水系统的供水温度宜为5~6℃，温差宜为7~8℃。

Air conditioning water system with large temperature difference design is a kind of energy-saving meas-ures,has important significance to understand the air conditioning water system with large temperature difference range. In this paper,the design of air conditioning chilled water system with large temperature difference on a large mall,were analyzed in the water chillers and chilled water pump unit refrigeration amount of energy consumption, the results showed that 6 ℃ /13℃ by using the engineering of the chilled water supply and return water temperature than the conventional 7℃ /12℃ of supply and return water temperature of chiller unit refrigerating capacity, in-crease energy consumption 0. 0011kW,the unit cooling capacity of chilled water pumps to reduce the energy con-sumption of 0. 01kW,calculate the annual energy consumption of air-conditioning season to save the operation cost of 106000 yuan. Suggestions of chilled water system with large temperature difference of the supply water temperature should be 5~6 ℃,temperature should be 7~8℃.
