Air Conditioning Project of a Office Building in Shanghai
Abstract：This is designed for ventilated air conditioning cooling project of a technical hotel located in Dalian. With the total building area of 32275 square meters, the hotel erects from the underground floor to the top floor including eleven floor, Which accommodates rooms opening at different hours and for different functions. Trading business of the first floor is equipped with all air system,While considering the differences which lie in the time and frequency the rooms are used, the room and multi-functional hall in the second floor use the air conditioning system. Manual regulation of air conditioning in offices and guest rooms should be available in order to meet personal needs, so these rooms also employ the system of fan coil fresh air. New air set alone can deal with the fresh air until it reaches the indoor standard and then can be released to the inner space.
In the basement is to send, drain the air and smog to make it fireproof. Air draining use the same pipe ,While other rooms use natural draining Without special draining system equipped. To each wind pipe fireproof are attached, switched on in peacetime and off otherwise. Different routes are used in water pipe system which is composed of two standing pipes separating the building into two sections to supply water, and therefore make the burdens of the pipes less uneven.
