he purpose of this study was to establish a uniform set of requirements for rating computer room air conditioning/handling (CRAC/H) units for dedicated cooling systems in data centers. With the revolution of Industry 4.0, there are many options for data center infrastructure. The next generation of hyper-scale data centers will no longer be limited to past cooling facilities, but will seamlessly integrate the new cooling systems becoming increasingly optimized and mission-critical. For data centers, there are four basic heat removal methods, with air-cooled, water-cooled, glycol-cooled, and chilled-water system, to cool IT equipment and to transport unwanted heat to the outdoor environment. And air distribution systems, room-based, row-based, and rack-based cooling methods, have been developed to address cooling problems. Data center cooling technology is also advancing and improving and new types of CRAC/H units and cooling procedures are being developed. But performance tests of cooling systems do not fully reflect all types of CRAC/H units, data center cooling mechanisms, and data center thermal guidelines for IT environments. Standards and guidelines for performance testing were analyzed by foreign and domestic cases. In this paper, a suggested performance test condition is included in the CRAC/H classification, test requirements, and rating requirements. |
