摘要：
介绍了武汉市某研发生产项目空调系统设计,舒适性空调采用冰蓄冷技术,冷水机组位于蓄冰装置上游,输配水系统为变流量二级泵系统,二级泵分环路设置。数据中心采用水侧自然冷却技术,配置闭式蓄冷罐作为应急冷源,输配水系统为变流量一级泵系统。空调末端划分内外区,采用变风量空调系统,内外区合用1套热回收型新风机组。室外空气湿球温度低于5 ℃时,开启冷却塔+板式换热器免费供冷,降低系统运行费用。
Abstract：
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.
