Application of Evaporation Precooler on Dry Air Cooler
Dry air cooler utilizes inexhaustible ambient air as the cooling medium and is a very economical cooling and condensing equipment,it is widely used in the petrochemical industry.The cooling effect of dry air cooler is mainly determined by the heat transfer coefficient,heat transfer area and heat transfer temperature difference.In this paper,starting from the temperature difference of heat exchange,a new evaporation precooler being different from the traditional spray humidification method was introduced to effectively reduce the incoming air temperature,while protecting the fin tubes.
