Title Design of air conditioning engineering for a shopping square in Shanghai
Abstract
This design is a shopping square in Shanghai City air conditioning engineering design, is a ground 12, underground 1 floors of the building. The main food and beverage, shopping malls, cinemas, office and other uses of the ground. Underground one is the equipment layer. The full air system is used in the whole building, and the indoor heat and moisture load is all borne by the treated air. The air distribution can be distributed according to the need of the air quality, and it can be used to make the air quality better, and has the strong ability of the air desiccant, and maintain the simple.
The cold and heat source of the air conditioning region is the water cooled centrifugal unit and the municipal heat supply network. Centrifugal chiller unit has a large amount of cooling capacity, compact structure, good regulation, reliable operation, technical skill and convenient maintenance. The municipal heat supply network is practical and inexpensive.It saves the initial investment, the use of cost is also cheaper.
Keywords Central Air Conditioning，all air system，cold and heat source
