Title    air conditioning design of a commerce building    in nanjing                                                  

Abstract

This design topic is a nanjing commerce building air conditioning design. One floor underground, the ground has a layer of 23. located in the downtown of nanjing. The building has a garage for the underground layer, five layer below market, 6-22 floors for commercial housing. All of them required air conditioning. In high-rise buildings, malls and offices concurrently at the same time two types of air conditioning mode, operating time is different.

This design adopts the air source heat pump units as the air conditioning cold and heat source. Air-conditioning, large space such as shopping malls,

Because office partition area is larger also uses the full air system.

Complete air system to choose square diffuser is flat pattern. Water system with the use of closed-level vertical way different. Stair adopt positive pressure air supply system. Garage set up under the smoke control system, selects the variable speed fan, exhaust, smoke when the fire breaks out.
