Abstract: A flow generation unit has: an external casing having intake and delivery openings; an internal casing at least partly in the external casing and defining a chamber allowing fluid flow. The internal casing has a respective intake opening allowing air flow introduction in the chamber and a respective delivery opening allowing air flow emission. The internal casing intake and delivery openings are in fluid communication with each other by the chamber. They are also in fluid communication, in particular direct, with the external casing intake and delivery openings. The unit also has: a fan engaged with the internal casing and generating, within the chamber, an air flow directed from the internal casing intake opening to the delivery opening; a damping element at least partly made of elastomeric material placed as a direct interposition between the external and internal casing. The damping element supports the internal casing in the external casing.

Abstract: A diffuser for air treating plants that includes a channel having a lateral wall axially extending between upper and a lower end portions defining in the interior thereof a chamber for the passage of an air flow, an inlet configured for introducing air into the chamber, a plurality of throwing through openings defined on the lateral wall for putting in fluid communication the chamber with the outer environment, a plurality of induction through openings defined on the lateral wall for putting in fluid communication the chamber with the outer environment. A predetermined number of throwing through openings of the plurality is spaced from a predetermined number of induction through openings of the plurality along a direction parallel to the axial extension of the channel; the predetermined number of throwing through openings has an air passage cross-section greater than an air passage cross-section of the predetermined number of induction through openings.

Abstract: The invention relates to an air-conditioning process, intended particularly for industrial buildings, by means of which air is admitted, at outdoor temperature, into the zone below the roofing, in order to decrease the thermal gradient between the upper and the lower part of the building, and thus diminish the dissipations of heat through the roof. A double ceiling made of porous, preferably translucent, material permits the uniform distribution, over the whole surface of the building, of the air flux shifting from the upper over-pressured area to the lower area.
