Title a complex building air conditioning design of Xuzhou city

Abstract

The graduation project is a complex building air conditioning design in Xuzhou city,which its construction area is 42,529 square meters.It has one layer underground，and 7 layers on the ground.The Basement includes garage ,mall and engine room , etc ,and ground one to four for shopping malls, five to seven for the office. According to the building and the need for local climate characteristics of ventilation ,this air conditioning engineering design includes wind system,water system and cold and heat source.

This design uses chillers for air-conditioning cold source. This city has an outdoor steam pipe network in winter,which sets heat exchanger replacement to exchanger heat. For conditioning mode,the mall adopts all-air syetem and the office building adopts a separate fan coil air system. The water system uses closed systems with different programs. Positive pressure air supply system is used in stairwell.Basement and equipment room sets smoke control system,with a variable speed fan.It is usually used to exhaust,but sometimens smoke in case of fire.

Keywords   mall air conditioning     all-air system  

Independent fan coil air system
