PERFORMANCE ANALYSIS OF AN AIR COMPRESSION REFRIGERATION SYSTEM FOR DATA CENTER COOLING

ABSTRACT
An air compression refrigeration performance calculation model applied to data center cooling was established, which is a reverse Brayton cycle system, the operation performance was studied by numerical simulation and the influence of supply air temperature, ambient temperature, pressure ratio, data center room temperature was analysed. The results showed that when the pressure ratio of the air compressor is 1.3, the system obtains the maximum cooling COP. Heat exchanger efficiency have a significant effect on the cooling capacity and cooling COP, the efficiency of the heat exchanger increases from 0.6 to 0.8, and the increase in cooling capacity is 4.84 kJ/kg, cooling COP increased by 23.2%, Compared to conventional vapour compression/loop heat pipe natural cooling systems, in cold regions, the annual energy efficiency of air compression refrigeration can reach to 13.85.
