Symphonylimited Symphony cooler NINJA MODEL has got so vide gap on both side that a fingure can easily insert bothside simultaniously.Speed is also too slow & the air is not tempted to pass through Honeycomb pad.I have found that is blowing hot air inside.How spesification of cooling an area of 160 Sqft it will give??Direct evaporative cooling (open circuit) is used to lower the temperature of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air. The heat of the outside air is used to evaporate water. The RH increases to 70 to 90% which reduces the cooling effect of human perspiration. The moist air has to be continually released to outside or else the air becomes saturated and evaporation stops. In the usual arrangement the pad is maintained in position so that the water can be eifectively dripped or sprayed onto it, and so that all of the air handled by the fan or blower is circulated through the pad so that a rapid rate of evaporation occurs at the pad, thus cooling the air that is circulated.The fan serves two functions; to draw outside air through the pads and into the unit, and to force this now cooler air out through the exit duct and into the area to be cool
