Conditioning device of the free cooling type

A free cooling conditioning device for climate-controlling of an enclosed space comprising a box-like containment body and thereinside:

• a first main fan for aspirating air from an enclosed or outside space;
• an evaporator, to which said first fan sends aspirated air in order to introduce the aspirated air in the enclosed space to be climate-controlled;
• a condenser operatively connected with said evaporator;
• a second fan for air flow passing over said condenser;
• a compressor, which is operatively connected with said condenser and said evaporator to form a refrigeration circuit for cooling aspirated air;
• and comprising a first shutter, provided upstream of said first fan, for selecting a stream of air aspirated by said first fan, from either ambient air, for a first direct-cooling conditioning mode, or external air for a second free cooling conditioning mode;
• and a second shutter, which is adapted to redirect air stream in output from said enclosed space either toward said second fan, when the device operates in the second free cooling mode, or toward said first shutter, which is at least partly open toward said first fan, for aspiration, at least partly, by said first fan of ambient air, in the first direct-cooling mode with ambient air recirculation.
