AIR COOLER :

AIR COOLER

    Air cooler works on the principle of evaporating cooling. It is generally used in dry climate as such it is sometimes called as desert cooler. In this case water is used as a cooling medium. The temperature of air is decreased (I.e. sensible heat is removed) by the water when air is brought in contact with the water. Water absorbs heat from the air and evaporates. To compensate loss of water due to evaporation, make up of water is added.

FUNCTION OF AIR COOLER

The basic components are fans, water pump and pads through which air is enter the cooler. The electric driven pump pumps the water from the bottom tank to the top headers. The header have holes through which the water trickles down and pass through pads fitted on three sides of the cooler. Air sucked through pads from three sides gets cooled . The cool air is discharged by the motor driven fan in to the room or space to be cooled. The direction of air flow can be adjusted with the help of grills fitted on the discharge side of the cooler. 

PRECAUTION S

For better performance pads to be changed every year and water tank should be cleaned from time to time
