This subject is located in Jiangsu Province, Siyang County, with a total construction area of 19473, underground floor1, ground floor 16, is a high –rise building. It is Reinforced Concrete Structure. Considering the characteristics of this building itself, the podiums are mainly used as mercial housing, so centralized can be used。 and the towers as office space, so fan coil units used. This system has the advantage of low investment, adjustment flexibility, easy operation and management and so on. According to the functional requirements and features of this multipleuse building, as well as the meteorological condition and aircondition requirements of this region, make reference to relevant documents to make a system planning, design calculations and equipment selection for its central aircondition system. For the selection of cold and heat source, considering that there is no fixed heat supply around the building, therefore the refrigerating unite system can be used for the cold source, and fuel steam boiler can be used for heat source, by this way to meet the need of the building’s cold and heat load. In addition, the generator room should be set in the equipment room of basement. Then make a calculation about the airconditioning load of winter and summer, about the new airquantity that each room needs。 meanwhile, make a calculation about the air duct, water pipe, refrigeration and heating system. Because of the characteristics of the building structure, put the cooling tower on the threestorey podium to meet the demand of refrigerating system. According to the calculation result, the pare and analysis to performance and economy, the choice of equipment and material have make sure that the equipment will satisfy people’s demand in capacity, shock absorber and noise elimination, and the system also achieve the purpose of energysaving
