Shutter movement device for climate control apparatuses

Abstract

A device for moving a shutter for blocking and diverting an air stream, in climate control apparatuses, comprising a rotating element actuated by an electric motor and pivoted to a containment frame for at least part of the machine body of a climate control apparatus, a first end of a traction and pusher cable being rigidly coupled to the rotating element, its opposite end being rigidly coupled to the louver of a shutter of the louver type to be moved. The cable is arranged slidable within a sheath fixed to the frame by means of two brackets, a first one proximate to the rotating element and a second one at the opening which can be closed by the louver.

What is claimed is: 
     
         1 . A device for moving a shutter for blocking and diverting an air stream, in a climate control apparatus, comprising: a containment frame for at least part of a machine body of the climate control apparatus; a rotating element; pivoted to said containment frame; an electric motor connected to said rotating element for actuation thereof; a louver type shutter comprising a louver; a traction and pusher cable that has a first end thereof rigidly coupled to said rotating element and a second opposite end that is rigidly coupled to the louver of said shutter to be moved, said cable being provided with a sheath which is fixed to said frame by way of two brackets, a first one of which is located proximate to said rotating element and a second one is located at an opening of the shutter which can be closed by said louver, the cable being further slidable within said sheath. 
     
     
         2 . The device of  claim 1 , wherein said rotating element is constituted by a spool, that is actuated directly by said electric motor or by way of reduction gears connected to an electric motor which actuates a cylindrical type shutter. 
     
     
         3 . A climate control apparatus of the free cooling type, having a box-shaped containment body and comprising arranged inside the containment body:
 a first main fan, for drawing air from an enclosed space or from an outside environment;   a first, cylindrical type shutter, located upstream of the first fan, for selecting an air stream aspirated by the first fan, from either ambient air for a first direct cooling conditioning mode or external air for a second free cooling conditioning mode;   an evaporator, to which the first fan sends aspirated air to introduce the air in an internal space to be climate controlled;   a condenser which is associated with said evaporator;   a second fan for providing a passage of air over said condenser;   a second louver type shutter, which is adapted to divert an air stream that exists from the enclosed space either toward said second fan, when the climate control apparatus is operating in the second free cooling mode, or toward said first shutter, which is at least partly open toward the first fan, to make said first fan aspirate at least partly ambient air, in the first cooling mode with ambient air recirculation;   a compressor, which is associated with the condenser and the evaporator so as to form a refrigeration circuit for cooling aspirated air;   a containment frame for at least part of a machine body of the climate control apparatus;   a device, for moving said second shutter, that is consituted by a rotating element, pivoted to said containment frame, by an electric motor for actuating said rotating element, by a traction and pusher cable that has a first end thereof rigidly coupled to said rotating element and a second opposite end rigidly coupled to a louver to be moved, said cable being provided with a sheath which is fixed to said frame by way of two brackets, a first one of which is proximate to the rotating element and a second one is located at an opening which can be closed by said louver, said cable being slidable within said sheath.
