Abstract: A flow straightener for axial fans particularly for conditioning systems, being constituted by a plurality of flat deflection walls, which form a substantially star-shaped profile which is adapted to be arranged coaxially and proximate to the impeller of the axial fan with which it is associated.

Abstract: A free cooling conditioning device for climate controlling of an enclosed space comprising, inside a box-like containment body, a first main fan for aspirating air from the enclosed/outside space, an evaporator, to which the first fan sends aspirated air to introduce it in the enclosed space, a condenser associated with the evaporator, a second fan for air flow over the condenser, a compressor, associated with the condenser and the evaporator to form a refrigeration circuit for aspirated air cooling, a first shutter, upstream of the first fan, for selecting the air stream aspirated by the first fan, from either ambient air, for a direct-cooling conditioning, or external air for free cooling conditioning, and a second shutter for redirecting the air stream in output from the enclosed space either toward the second fan, in the second free cooling mode, or toward the first shutter, at least partly open toward the first fan, for aspiration of ambient air, in the cooling mode.

Abstract: An uninterruptible power supply of the type provided with a cooling system for controlling the temperature of its components which generate heat the most, the cooling system being of the type with a refrigeration cycle and having a refrigeration container inside which at least one of the components which generate heat the most is arranged.
