杭州某银行数据中心空调系统设计

Design of HVAC System for a Bank Date Center in Hangzhou

数字经济时代,越来越多的金融企业为了创新与发展,纷纷自建数据中心。总部坐落于市中心的企业,受土地成本的制约,往往把数据中心、企业办公及生活配套等功能融合在一幢综合楼内。鲜有文献介绍高层综合楼类数据中心空调系统的设计,通过杭州某银行项目详细介绍了高层综合类数据中心暖通系统设计思路,结合本项目用能特点及气候特征,采用了高效空调设备以及自然冷却、变频、封闭冷通道、高温冷冻水、特别是回收数据中心的余热用于办公采暖等节能技术,控制电能利用效率(PUE)设计值为1.33(立项时政策控制值为1.4),为高层综合内数据中心类项目的空调系统设计提供了参考。

In the era of digital economy,more and more financial enterprises are building their own data centers for innovation and development.Once enterprises headquartered in the center of the city,they usually integrate functions such as data centers,corporate offices and living facilities into a single complex constrained by land costs.There is little literature on high-rise mixed-use data centers,Taking a high-rise mixed-use data center of a bank in Hangzhou as an example,his paper present the design of air conditioning system,combined with the energy consumption characteristics and climate characteristics of the project,using high-efficiency air conditioning equipment,making full use of free cooling,frequency conversion technology,closed cold channel,selecting high-temperature chilled water,in particular,waste heat recovery from data centers is used for office heating,to achieve PUE at a low lever 1.33(the policy control value is 1.4).It provides a reference for the design of air conditioning system for data center projects in high-rise complexes building.
