<p>An air conditioning apparatus for use in industrial facilities includes a housing subdivided into three compartments by two partitions spaced from one another along the height of the housing. The top compartment is formed with an opening on its side wall and provided with a fan positioned on the top of the housing. The foul air admitted into said opening is extracted into atmosphere by the fan. A number of fans are also positioned on the middle partition and a number of respective openings covered with gratings are provided on the walls of the middle and the bottom compartments. All the fans are electrically controlled from outside of the housing to draw air through the apparatus for refreshing air in the room, for filtering, heating or humidifying air in the room when desired.</p> |
