Design and analysis of air conditioning system of Wuhan Founder Financial Center

This paper presents the design scheme of the cold and heat sources, air system and water system of Wuhan Founder Financial Center project, and analyses the specific technical measures of the high-efficiency refrigerating plant room in the office area. By comparing the system energy efficiency and economy of different schemes, the office area is finally determined to adopt the low-temperature air supply all-air variable air volume (VAV) system. The inner area adopts the single air channel type VAV, and the outer area adopts the hot water reheating coil parallel type fan power box terminal. The commercial area is equipped with a separate cold source, and the air conditioning water system adopts a zoning four-pipe system with two pipes in the outer area and four pipes in the inner area. Cooling tower is used in transition season and winter to reduce the operating cost of the system.
