Thermal characteristic analysis of regular stuffing spray air coolers

Analyses and calculates the thermal characteristics of the key equipment—air cooler for indirect free cooling tower used in communication rooms. The results show that the more stuffing height is, the more total heat exchange is, the less spray water temperature is, the less stuffing height is under the same heat exchange. When the temperature of cold water is decreased by 1 ℃, the stuffing height is decreased by merely 5 cm and it is not very significant compared with increased cold water temperature, and the inlet cold water temperature generally is determined as 13 ℃.
