摘要：
介绍了该工程的空调冷热源、冷热水系统和冷却水系统的设计。该工程采用了复合式能源供冷、供热——燃气锅炉和直燃型溴化锂吸收式机组供热、直燃型溴化锂吸收式机组和电驱动型离心式冷水机组供冷。着重阐述了空调通风系统设计，根据建筑功能分区分别设计采用可变新风比的一次回风全空气系统、风机盘管加新风系统、直流式空调系统等。
Abstract：
Presents the design of air conditioning cold and heat sources, and chilled water, hot water and cooling water systems. The project adopts complex energy sources for cooling and heating, i.e. gas-fired boilers and direct-fired lithium bromide absorption refrigerators for heating, direct-fired lithium bromide absorption refrigerators and electric-driven centrifugal chillers for cooling. Elaborates the air conditioning and ventilation system design, which adopts the primary return air all-air systems with variable fresh air ratio, fan coil plus fresh air systems, straight-flow air conditioning systems, etc. according to different function zones.
Keywords:complex energy source, primary return air all-air system with variable fresh air ratio, indoor air quality, air conditioning system, cold and heat source
