Application research of wetted film evaporative cooling technology in telecommunication machine rooms
In a data center hub building in northwest China,due to the shading of buildings and the dense arrangement of outdoor units,the condensing efficiency of the air conditioning system decreases,especially in the summer when the temperature is high,which will increase the air conditioning load and may even cause the equipment to overheat and shut down.In this study,we propose to use wet film evaporative cooling technology to pre-cool the air entering the condenser to enhance the heat dissipation performance of the condenser.After the actual test,when the ambient temperature is 39℃,the inlet temperature of the outdoor unit is reduced by 11℃,the power consumption of the unit is reduced by about 22％,and the cooling capacity of the unit is increased by about 11％,and the comprehensive energy-saving effect is remarkable.
