The cooling load is 1627.1kw,while cooling indexes is about120.38W/m2. And the heat load is 963.259kw , heat indexes is 71w/㎡. According to the building’s functional requirements application ,I analyzed and compared a variety of air-conditioning models and chose the fan-coil unit with fresh air system and the all-air system.The study content mainly includes: cooling and heating load calculation of air conditioning in the building;the determination of the supply air volume and the fresh air volume;the air-conditioning system division;the selection of modes of air conditonding system;the selection of air conditoning equipment;the selection of the cold and heat source;the design and caculation of the air system;the design of the air duct system; the determination of air supply mode and air distribution mode;the design and the hydraulic calculation of the water system;the determination of the cold and heat source;the thermal insulation design of the pipeline, the design of the smoke prevention and exhaust and the design of noise elimination and vibration prevention.This central air-conditioning design not only can satisfie the thermal comfort but it ,to a great extent,can meet the command of building energy-saving.
