天津滨海国际机场二期制冷站水蓄冷空调设计

Water Cool Storage Air-conditioning System of Tianjin Binhai International Airport Phase Ⅱ Refrigeration Station

水蓄冷空调系统可充分利用国家的分时电价政策,运行费用可节省约25%以上,并能移峰填谷,平衡电网负荷,从而取得良好的经济和社会效益。本工程为某国际机场二期扩建项目制冷站工程,新建2#制冷站为T2航站楼和综合楼提供冷源,建筑面积共30.7万m2,冷源采用水蓄冷方案。介绍了水蓄冷的原理、水蓄冷方案和设计、运行效益分析等,并对设计日逐时负荷进行分析,根据季节制定出相应的运行策略。本设计对水蓄冷项目的广泛开展有很好地借鉴作用,为我国建筑节能起到良好地示范作用,并对机场等大型项目的制冷站建设提供参考。

Water cool storage air conditioning system can make full use of national time-of-use electricity price and operation cost saving about more than 25%. It can meet with peak load leveling of power system also. This project is for the Phase II refrigeration station of an International Airport. The new 2 # refrigeration station, water cool storage air conditioning system is adopted for it, will provide cold source for T2 terminal and Complex building air conditioning system. The T2 terminal and Complex building area is about 30.7 million m2. This paper will introduces the principle of water cool storage and water cool storage program, water cool storage design, water cool storage operation and the benefit analysis. Designing date hourly load will be analyzed and the corresponding according to season operation strategy formulated. This design of water cool storage project will widely develop a good reference for Chinese building energy efficiency and provide reference for the large projects refrigeration station construction such as airport.
