夏热冬暖地区某机场航站楼集中供冷方案对比研究

Comparative Study on Centralized Cooling Schemes for an Airport Terminal in the Area with Hot Summer and Warm Winter

夏热冬暖地区机场航站楼具有建筑体量大、功能复杂、全年供冷需求大等关键特点,合理设计集中供冷系统及方案对其节能高效运行至关重要。文章结合夏热冬暖地区某机场航站楼实际需求与工程特点,深入对比常规供冷方案、水蓄冷供冷及冰蓄冷供冷方案的能源消耗与经济效益,明确了蓄冷方案在实施过程中需要关注的关键环节,从而为同类型项目集中供冷方案设计提供案例参考。

The airport terminal in the area with hot summer and warm winter has the key characteristics of large building volume, complex function and large annual demand for cooling. Rational design of centralized cooling system and scheme is very important for its energy saving and efficient operation. Based on the actual demand and engineering characteristics of an airport terminal in the area with hot summer and warm winter, this paper deeply compares the energy consumption and economic benefits of conventional cooling scheme, water storage scheme and ice storage scheme, and clarifies the key links that need to be paid attention to in the implementation of cold storage scheme,so as to provide case reference for the design of centralized cooling scheme for similar projects.
