Abstract：

The Canton Tower has a complex shape structure with the height of 600 meters. It is divided into five function zones. According to the functions of each zone, adopts water-cooled centrifugal water chillers in the lower zones and split air-conditioners in partial independent operation rooms and equipment rooms, and air-cooled modular chillers in the upper zones. Both cooling and chilling water systems use frequency-controlled primary pumps in the lower zones. Redundancy air conditioning design is used in the broadcasting equipment rooms. By performance-based fire protection analysis, enhances smoke control and extraction system design. Considering strong wind in upper air, arranges the supply and exhaust outlets under the floor plate or around the peripheral of the roof sinking trench to reduce the effect of wind power. Presents briefly the indoor and outdoor design parameters, zoning of the air conditioning system, cold and heat sources, water systems, air systems, ventilation in normal times, smoke control and exhaust systems and auto control of air conditioning. Combined with the characteristics of the project, describes the design concepts, technical measures and technical difficulties for the project. According to the operation situation, summarizes the gains and lessons of the HVAC engineering.
