Definitions
- the present invention relates to air driving means for driving the air in ventilation systems, proposing a ventilation unit intended for being incorporated in industrial ventilation systems, with structural features determining an advantageous embodiment for the silent operation of said unit.
- Axial tubular fans which are intercalated in the air circulation ducts are known for driving the air in ventilation systems, the body of these fans being formed by a cylindrical casing in which an air driving element and the operating elements for the operation thereof are housed, said casing being coupled at its ends to an air circulation duct.
- the intercalated arrangement of the assembly of these fans in the air ducts favors the transmission of operating noise through said air circulation ducts, to prevent that transmission of fan operating noise there are conventionally provided silencers which are incorporated on the sections of the air duct to which the fan is coupled, or they are intercalated between said sections of the air duct and the fan, before and after same, which causes a considerable longitudinal prolongation of the fan, limiting the assembly possibilities of the system of application, said prolongation further being determined by the diameter of the air duct in which the fan is arranged, since longer silencers are required the greater the diameter of the air duct.
- the ventilation units used in industrial ventilation systems have a structural formation which comprises a body-unit provided with a direct air inlet opening at one end and an air outlet opening at the other end, including therein an air driving propeller facing the air inlet opening; the adaptation of solutions which allow achieving an effective soundproofing with small silencers, given the large diameter of the air ducts to which said units are normally coupled during application, and which require oversized silencers with conventional solutions of placing silencers on the air ducts being of particular interest in these ventilation units.
- the invention proposes a ventilation unit which is made with a structural formation that allows achieving a very effective soundproofing effect with a small silencer regardless of the diameter of the air ducts to which the unit is coupled in the systems of application.
- This ventilation unit object of the invention comprises a structural assembly formed by a body-unit establishing an air inlet opening and an air outlet opening at the ends, respectively, internally housing an air driving propeller arranged in the air inlet opening, said air inlet opening being shifted outwards, there being included between the air inlet opening and the air driving propeller a tubular silencer, which establishes an air passage conduit having a smaller diameter than the air inlet mouth.
- a suitably soundproofed ventilation unit with very minimal increase in the longitudinal dimension is thus obtained, since the silencer which is arranged between the air inlet month and the air driving propeller has a diameter smaller than the external air ducts to which the ventilation unit is coupled, therefore requiring a shorter silencer compared with the silencers arranged between the openings of the ventilation unit and the external air ducts in conventional solutions.
- the ventilation unit offers advantageous conditions for assembly in the systems of application since the soundproofing minimally increases the longitudinal dimension, allowing a more versatile assembly of the ventilation unit in the systems of application.
- said ventilation unit object of the invention has very advantageous functional features, acquiring its own identity and preferred character with respect to conventional ventilation units having the same application.
- FIG. 1 shows an exploded perspective view of a ventilation unit made according to the invention.
- FIG. 2 is a schematic longitudinal section view of a ventilation unit according to the invention, air circulation through the unit being indicated with lines.
- the object of the invention relates to a ventilation unit of the types used in industrial ventilation systems, comprising a body-unit ( 1 ) inside which there is housed an air driving propeller ( 2 ) arranged in an air inlet opening ( 3 ) defined at one end of the mentioned body-unit ( 1 ), whereas an air outlet opening ( 4 ) is defined at the other end, both openings ( 3 and 4 ) establishing respective couplings for attachment to respective external air ducts.
- the air inlet opening ( 3 ) is shifted outwards with respect to the body-unit ( 1 ), there being included between the air inlet opening and the air driving propeller ( 2 ) a tubular silencer ( 5 ), which establishes an air passage conduit having a smaller diameter than the air inlet opening ( 3 ) between the mentioned air inlet opening ( 3 ) and said air driving propeller ( 2 ).
- the silencer ( 5 ) is thus included integrated in the ventilation unit itself in an area having a smaller diameter than the couplings to the external air ducts of application, so said silencer ( 5 ) must be shorter than the conventional silencers which are arranged in the mentioned external air ducts for coupling the ventilation units in the systems of application, such that with this solution of the invention, in the assembly of the ventilation unit the arrangement for soundproofing the operation of the ventilation unit only involves a minimum increase in the length of the ventilation unit, allowing better conditions and greater versatility for assembly in the systems of application.
