Abstract
Abstract 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.

Claim 1
Independent Claim
217 words
An air conditioning apparatus for use in industrial facilities such as farming, animal husbandry, or the like, comprising a housing bounded by external walls and having a top, said housing being subdivided into a bottom compartment, a middle compartment and a top compartment by partitions spaced from one another along the height of said housing, each of said compartments including at least one opening formed on the respective external wall; and a number of fans located in said housing and provided with humidifying means, a least one of said fans being provided with a heating unit; electrical means mounted outside of said housing and operatively connected to said fans, said fans being electrically controlled by said electrical means so as to create a first air flow which is drawn in and expelled from the apparatus through said top compartment for extracting of foul and toxic air from an enclosed room in which the apparatus may be positioned, a second air flow which enters said housing thrugh one of said openings, circulates within said housing in closed circuit and leaves said housing in warmed or condition, and a third air flow which enters said housing from atmosphere through one of said openings and leaves said housing through another of said openings for renewal air in the enclosed room.

Dependent Claim
14 words
The apparatus of claim 1, wherein said housing has a shape of a parallel-piped.
Claim 4
Dependent Claim
21 words
The apparatus of claim 2, further including a number of gratings, each of said openings being covered with a respective grating.
Claim 5
Dependent Claim
73 words
The apparatus of claim 3, wherein said housing has a front wall, one of said openings being formed on said front wall in the region of said top compartment to admit air into said top compartment, said top being communicated with the atmosphere, one of said fans being mounted on said top to create said first air flow and to extract the foul or harmful air from the enclosed room to the atmosphere.
Claim 6
Dependent Claim
24 words
The apparatus of claim 4, wherein one of said partitions is a middle partition, all the remaining fans being mounted on said middle partition.
Claim 7
Dependent Claim
140 words
The apparatus of claim 5, wherein two of said openings are formed on said front wall in the region of said middle compartment and one opening is formed on said front wall in the region of said bottom compartment to admit air into said bottom compartment and wherein a shell-shaped deflector is provided in said middle compartment in communication with one of the openings of said middle compartment, said opening of said bottom compartment being in communication with said one of the openings of said middle compartment, said fan provided with a heating unit being arranged in said middle compartment to create said second air flow so that air admitted into said bottom compartment circulates in closed circuit in said middle compartment and leaves the housing through said one opening of said middle compartment in warmed moist condition when desired.
Claim 8
Dependent Claim
24 words
