what is function of desert cooler in relation to evaporation Share with your friends Share 0 Geetha answered this For evaporation to occur the liquid should absorbs energy in the form of Latentheat and the amount of heat needed to evaporate the liquid is absorbed from the surrounding.Desert cooler involves the process of cooling and humidification. In desert humidity is very less and temperature gradient more making high rate of evaporation. Desert cooler makes cooling the surrounding air, water droplets are added so as to reduce the rate ofheat transfer. Thus rate of evaporation reduced. 0 View Full Answer
