Performances of externally-cooled multi-stage evaporative cooling AHU

Presents the air handling process. The supply air parameters of the units in summer are mainly related to intake air parameters, intake water temperature, ratio of air to water, efficiency of the direct evaporative cooler. Based on the analysis of influencing factors, draws the chart of supply air parameters in summer of the units applied to different regions, and presents an example of calculating the supply air parameters. Calculates the capacity of the units operating in summer.
