ANALYSIS OF COOLING SYSTEM EFFICIENCY

Yuri Dmitriev

Abstract


Introduction: The main task of cooling systems in the machine room of a data center is to maintain optimal air parameters at the inlet to IT equipment in accordance with the applicable regulatory documents. If the value of air temperature at the inlet to IT equipment exceeds the optimal value, then so-called hot spots occur — the operation of IT equipment in such places can lead to its overheating and failure. The main reason for the occurrence of hot spots is the violation of air circulation between the hot and cold aisles. Purpose of the study: We aimed to analyze the influence of different methods of hot aisle isolation on the efficiency of IT equipment cooling. Methods: We performed modeling of different methods of hot aisle isolation at different capacity values of IT equipment in the STAR-CCM+ program. Result: As a result of studying temperature and air conditions in a data center, we found the most rational way of isolating the hot aisle — top horizontal containments with vertical blind panels in the free rack space.


Keywords
