Abstract
An air conditioner for a coating booth is constructed so as to intake the air through a filter for eliminating dust, to heat the air by a plate fin coil heater to the extent that it is not excessively saturated, to atomize the steam directly into the air via a steam atomizing tube, to contact the air including the atomized steam with water flowing down on the surfaces of the wet walls, to make the recirculating water absorb the steam for giving energy for humidifying to the water, to humidify the air by contacting the flowing water and to feed the humidified air through an eliminator to a coating booth at a temperature controlled by another plate fin coil heater.
Claims8
An air conditioner for a coating enclosure comprising:
- means for drawing air through an air filter;
- first means for heating said filtered air;
- means for humidifying said heated air by contacting said air with heated water flowing on wet walls;
- second means for reheating said humidified air, means for feeding said reheated and humidified air into said coating enclosure, and
- steam atomization means provided between, in the direction of flow of said air, said first means for heating the air and said means for humidifying the air, said steam atomizing means being constructed for spraying steam directly toward said wet walls to heat said water.
A method for conditioning the air of a coating enclosure comprising steps of:
- drawing air through an air filter;
- heating said filtered air;
- flowing water down wet walls;
- atomizing steam directly onto said wet walls in such a manner that the atomized steam contacts water flowing down said wet walls to heat said water;
- humidifying the air by contact with said heated water flowing down said wet walls;
- eliminating the water droplets in the humidified air by means of an eliminator;
- and
- heating the air again to a predetermined temperature.
