This paper presents the design of the air conditioning system for a research and production project in Wuhan.The comfort air conditioning adopts ice storage technology,with the chiller located upstream of the ice storage device.The water distribution system is a variable flow secondary pump system,and the secondary pumps are set in separate loops.The data center uses water-side natural cooling technology,and is equipped with a closed cold storage tank as an emergency cold source.The water distribution system is a variable flow primary pump system.The air conditioning terminals are divided into inner and outer zones,and a variable air volume air conditioning system is adopted.The inner and outer zones share a set of heat recovery outdoor air units.When the outdoor air wet bulb temperature is lower than 5 ℃,the cooling tower and plate heat exchanger is turned on for free cooling to reduce the operation cost of the system.
