Abstract

The failure of air conditioning refrigeration system will lead to the rapid increase of temperature in data center, which will lead to server downtime. In this paper, the CFD method is used to simulate the nine working conditions of underfloor air conditioning, in-row air conditioning and overhead air conditioning, which are respectively composed of no containment, cold aisle containment and hot aisle containment. Taking the time required for the maximum inlet air temperature of the cabinet to rise to the limit temperature (45 ℃) for the normal operation of the server as the evaluation standard, the reliability of the air conditioning scheme after the failure of the refrigeration system is studied. The results show that the reliability of hot aisle containment is the highest when using underfloor air conditioning and overhead air conditioning, and the reliability of cold aisle containment is as same as hot aisle containment when using in-row air conditioning scheme. In the case of hot aisle containment, the ability of the three air conditioning schemes to bear the failure risk of refrigeration system is as follows: underfloor air conditioning (> 900s) > overhead air conditioning (870s) > in-row air conditioning (570s).
