Abstract：
Presents the optimized air conditioning and ventilation system design. Takes several energy saving measures for air conditioning system， such as large capacity centrifugal chillers working with variable frequency small capacity chillers， variable frequency and variable flow control on secondary pump water systems， cooling tower for fourpipe water system in winter， fancoil unit for commercial peripheral zones and allair systems for interior zones， variable frequency control on supply and exhaust air fans， enthalpy control on fresh air cooling in winter and intermediate season.
