Central Air Conditioning System Design for an Administration Building in Suzhou
Abstract: The graduation project designs a central air conditioning system for an administration building in Suzhou. It can meet the requirements of cooling in summer and heating in winter, to provide a healthy and comfortable working environment for the people inside. The administration building has eight floors, mainly offices, conference rooms and lounges. The design content includes air - conditioning system cooling load calculation, comparing and determining the system scheme, the selection of cold and heat sources, the selection of fresh air units and fan coil units; air system design, layout and hydraulic calculation; the selection of indoor air supply way and air distribution form;water systems design, layout and hydraulic calculations;muffler design, shockproof design etc.The design considers requirements of energy efficiency and comfort, air-conditioning system shall be designed to use variable refrigerant volume - fresh air system, each layer has its own fresh air unit which is sent to the fresh wind.
Keywords: Administration building; Central air conditioning;Cold and heat load; Variable refrigerant volume -fresh air system
