Abstract：

Presents the main design conditions, air distribution mode, smoke control and exhaust system and automatic control system, etc. Summarizes the design experience. The office rooms apply fan-coil unit plus fresh air system; the large spaces apply double-fan all-air system. The building is divides into inner and peripheral zones. The inner zone is supplied with chilled water of 7 ℃/12 ℃ all the year by water chillers in transition seasons and summer and by cooling tower in winter. The peripheral zone is supplied with hot water of 60 ℃/50 ℃ in winter which is obtained from exchanging with the municipal heat supply network by plane heat exchangers. Water system uses zoning two-pipe system. Both chilled water pumps and cooling water pumps are operated with variable frequency.
