Title    Shopping Mall Ａir-condition Design In Yangzhou 

Abstract

The topics for graduate design a shopping mall air-conditioning design in Hangzhou.The construction area of about 17000 square meters. Building underground layer two, the ground layer three, where in the two layer underground underground garage, wartime personnel shelter, underground layer of equipment room, management office and some shopping malls, supermarkets, one or two ground floor shops and supermarkets, the three layer is for the office rental business.

This design uses the screw water chillers as cold source of air conditioning, using gas boiler as heat source. Air conditioning, large space such as shopping malls, office hall, supermarket, adopt the whole air system, business office and commercial uses of fan-coil unit plus fresh air system, air system choose square diffuser jet form, and the fan - coil and independent new wind system square diffuser for flat form, water the system adopts closed the level of different vertical different process. The toilet ventilation unified by the exhaust fan is connected, the check valve installed in the terminal. Stairwell pressurization system; basement, equipment rooms set smoke control system, optional variable speed fan, exhaust peacetime, when the smoke of a fire.
