Abstract
To address the challenges of ensuring business continuity and managing limited space during the retrofitting of existing data center air conditioning systems,this paper presents a case study of a retrofitting project in a Guangzhou data center.This case study meets these requirements without affecting the normal operation of non-retrofit areas.The implementation involves first constructing a backup cooling system to meet the air conditioning demands of IT equipment during the renovation.Once this system is stably operational,a new high-temperature chilled water system is constructed.Calculations indicate that the retrofitted data center zone achieves an annual PUE of 1.3 or less,representing a 12.7％reduction compared to the pre-retrofit system.Furthermore,given 1,580 annual hours with an outdoor air wet-bulb temperature at or below 13° C,the implementation of natural cooling via a plate heat exchanger lowers the annual PUE by approximately 1％relative to the scenario without natural cooling.关键词
