This paper provides the design of central air-conditioning system in an office building. The building consists of four layers, a layer of 1677.02 m2, 1343.26 M2 two layer, three layer fourlayer 1667.06 m2, 1681.36 m2. Construction area is about 6358.7 m2, met every layer structure, the layer is 4 meters tall, including office, reception room, multimedia room, record room. The office is located in Beijing, according to the actual characteristics of the localclimate conditions and the building, by comparing the different air conditioning scheme,considering the energy saving and installation complexity, analysis and comparison of several typical of central air conditioning system, the VRV system, it is through the circulation to control refrigerant, and direct evaporation the refrigerant refrigeration implementation, theuse of frequency adjustment, to meet the comfort requirements, and achieved good effect of energy saving and emission reduction. Based on the calculation of cooling load of each roomand fresh air load, on the indoor and outdoor machine, air equipment, equipment selection and layout, and the design and selection of piping. The design can meet the office building in summer cooling needs.
