The air cooling apparatus comprises a plurality of mist generating chambers having a plurality of piezo electric ultrasonic atomizers to create mist of fine liquid particles that can unanimously mix with air stream generated by the air circulation unit, like centrifugal fan.
BACKGROUND
[002] Background description includes information that may be useful in understanding the present subject matter.
[003] Existing evaporative coolers are working on the principle to generate vapours of water for generating cooling effect which requires cooling pad for evaporation of water and a water pump to supply water to all cooling pads. The evaporative coolers work efficiently during hot conditions and have bad impact on health during humidity conditions.
[004] Technical problem associated with existing evaporative coolers is high running cost and maintenance cost.
[005] Another technical problem associated with the existing evaporative cooler is water droplets size which is big that create moisture in the environment and threat of corrosion to surrounding components prone to rust.
[006] Another technical problem associated with the existing evaporative cooler during humid days is that water droplets remain on the human body to increase discomfort and increase heat index. The impact of humidity is discomfort which can result in to fatigue, dehydration, muscle cramp, etc., to humans.
[007] Another technical problem associated with the existing evaporative cooler is wastage of water or liquid.
[008] With the big size of water vapours or water droplets in the existing fan unit and the evaporative cooler, the water vapours or water droplets gets settle down in short span of time which reduces the cooling effect.
[009] Accordingly, the existing evaporative coolers are not efficient in terms of cooling for long time and comfortable cooling to human beings.
[0010] There is need in the art to provide a system that can eliminate the above mentioned technical problems with less manufacturing and operational cost.
