Abstract: Maximizing utilization of natural cold energy has become the key to reduce the energy consumption of data center air-conditioning system. A new type of evaporative condenser with water-cooled condensation is proposed and used in the data center composite air conditioning system. The model of air conditioning system is established and verified by the experimental platform. The simulation results show that although the coefficient of performance (COP) of the evaporative cooling heat pipe mode is reduced by 0.88% on average by the proposed evaporative condenser, the upper limit of temperature operation of this mode is raised from the original 15 °C to 17 °C. The heat pipe mode has been extended throughout the year, and the advantages of energy saving have been fully utilized. For the evaporative cooling vapor compression mode. The proposed evaporative condenser can reduce the energy of the composite system, and the COP is increased by 9.82% on average, showing high operating performance.
