Abstract:
Though limited in its use depending upon regions
and seasons, the room air conditioner is can be used
anywhere in tropical and subtropical areas. With the
improvement in the living standard, the demand for
adjusting the room temperature to an agreeable extent
suitable for human activities is gradually increasing.
Furthermore, places of its use include not only public
places and offices but also automobiles, living rooms,
resting rooms and places of amusement.
When reviewing the actuating principle of a room
air conditioner, it simultaneously performs actions of
cooling, dehumidification, dust removal and air suction
and discharge. First of all, its cooling system is almost
identical to that of a refrigerator but the compressor
motor is much larger and the air suction is carried
out by the fan, with the dust in the air removed by
the air filter in the front part of the room air conditioner.
The cooling takes place when the vapor passes
through the space of cooler. The temperature of moisture
in vapor falls below the dew point and condenses
into water droplets, which are discharged into atmosphere
by a fan through the back side of the cooler.
