Design of HVAC system for a research complex building

This paper presents the design of air conditioning cold and heat source, water system and data center heat recovery system, and discusses the annual operation plan of three cooling systems, including data center chiller, free cooling of cooling tower and waste heat recovery. The combined utilization of the water-source VRF system and water-source heat pump system in research office area is analysed in detail. The comprehensive utilization of the air conditioning system and energy of the complex building is realized through the heat recovery system of the data center.
