Development of dew-point evaporative cooling technology and its application to data room cooling

The dew-point evaporative cooling can decrease the air temperature below the inlet air wet-bulb temperature, ideally reaching the dew-point temperature of inlet air. The cooling performance of dew-point evaporative cooler is affected by the surface wetting material of wet channel, cooler structure and operational parameters. Summarizes the status and development of dew-point evaporative cooler in the aspects of the selection of wet channel materials, the optimization of cooler structure and operational parameters, as well as its different application forms in data room cooling.
