Abstract：

Presents the design of cold and heat sources, heating, air conditioning, ventilation, smoke control and extraction and automatic control systems. The office zones in standard floors adopt four-pipe water system, VAV air conditioning system and radiator heating system, and inner and peripheral zones sharing the same VAV unit. The large spaces such as the perpetual garden and the halls adopt low-temperature floor panel heating systems. Most registers are installed in outdoor green area, and some measures including sound attenuation, filtration, waterproof and drainage are taken in air intakes and exhaust shafts. Outdoor air is  directly supplied into air conditioning units without prehandling. The air conditioning system is of variable frequency operation.
