Title A building air condition system design of Zhangjiajie International Cultural Exchange Center
Abstract The topic for graduate design is the air-conditioning system design of a certain international ethnic cultural communication center building complex in Zhang Jiajie. The building complex is a comprehensive high-rise building, which has guest rooms, entertainment facilities, catering and exhibition functions. The area of the construction is about 3100 square meters, and it has fifteen floors totally. The first floor to the fifth are some rooms mainly used for exhibition, canteen and entertainment, and the sixth to the fifteenth are all guestrooms. The design uses air-condition for the refrigeration in summer and heating supply in winter, with the water chilling unit and electric boiler as the source of cold and heat. According to the types of different rooms, the high and large spaces, such as exhibition rooms and showrooms, use all-air system, and guestrooms and entertaining rooms use fan coil and dedicated outdoor air system. The all-air system chooses flat jet form of square diffuser, and for those high and special spaces like showrooms, it uses twist outlet as the air terminal device. Fan coil and dedicated outdoor air system are pided into two types. Entertaining rooms, with a long depth, choose Fan coil of high pressue, and guestrooms choose Baiye outlet side in the form of delivery. The air-water system mainly uses closed path way. The guestrooms use natural ventilation mode, and the space for entertaining uses centralizing mechanical ventilation. The ventilation of bathrooms uses exhaust fan, installing check valve in tail end. The necessary areas install smoke control system, and the atrium and showrooms use mechanical exhaust system.
Key words: Water Chilling Unit, All-Air System, Fan Coil + Dedicated Outdoor Air System
