Air conditioning and ventilation system design for the new medical zone of Xiangya Hospital of Central South University

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.
