Title    International Hotel in Nanjing Air-conditioning Design                     

Abstract The topics for graduate design a international holtel in Nanjing air-conditioning design. The construction area of about 45,873 square meters. building underground is one story and ground is thirteen stories, which is usually a ground floor premises equipment, underground garage, in wartime To staff the shelter by a second-class - for the four-story shopping arcades, Internet cafes, office, entertainment and other public facilities, five to seven for the office space, eight to thirteen for hotels, is shopping, leisure, office and Front as one of the high-rise building.

This design uses centrifugal chiller as a source of cold. Air-conditioning, large space such as shopping malls, office lobby, rooms and other activities by the entire air system, office, hotel rooms and other fan-coil and independent use of the new air system. System-wide choice of air flow. Water system with the use of closed-level vertical way different. Bathroom ventilation fans to unification by a row, the check valve installed in the terminal. Stairwell use positive pressure air supply system; basement, equipment room equipped with smoke extraction system, optional variable speed fans, exhaust peacetime, when the smoke of a fire.
