Annual Operation Effect Analysis and Adjustment Strategy of Indirect Evaporative Cooling Air Conditioner in Data Center
In order to comprehensively analyze and accurately evaluate the operating effect of indirect evaporative cooling air conditioners in data centers throughout the year,this paper analyzes the enthalpy humidity chart and the air treatment process,and puts forward evaluation indexes of efficiency in wet and dry conditions to describe the operating performance of indirect evaporative cooling air conditioners in data centers.It is found that the operating parameters and energy efficiency parameters of the indirect evaporative cooling air conditioner mainly change with the change of secondary air and ambient air.When the relative humidity of the return air in the primary air room increases by 10%,the return air enthalpy increases by 9.4kJ/kg.In addition,during the annual operation and adjustment process of indirect evaporative cooling air conditioners in data centers,the recommended switching values of dry mode and wet mode are respectively 14℃for dry bulb temperature and 19℃for wet bulb temperature,which can regulate the annual energy efficiency of the system by controlling the water volume of wet channel,secondary air volume and the switching point of dry and wet modes.
