Definitions

  • the present invention relates to a controlled mechanical ventilation unit for ventilation systems in buildings. These units enable air to be extracted from different rooms of a building in a controlled manner by sucking the air through a fan. Air is conducted from the rooms to the unit and from the unit to the outside of the building through separate air ducts that are connected to respective air inlets and outlets of the unit.
  • controlled mechanical ventilation units comprising a polygonal prismatic, normally rectangular, casing with a plurality of pairs of sides that are facing each other.
  • the casing houses a centrifugal fan to move air from a plurality of air inlets to one air outlet.
  • Said air inlets and outlets are transversely arranged on the sides of the casing, i.e., passing through said sides.
  • the centrifugal fan By means of the centrifugal fan, the air is driven by an impeller that sucks it in through the centre of the unit from the air inlets and expels it through the blades thereof in a direction perpendicular to the rotation axis of the impeller towards the air outlet.
  • the centrifugal fan is arranged in the polygonal prismatic casing with the rotation axis of the fan parallel to the straight sides or lateral faces thereof, i.e., perpendicular to the upper and lower faces of the casing.
  • These units are fixed to the ceiling, wall or, more commonly, inside the false ceilings of homes.
  • the prismatic shape of the casing with the inlets and outlets arranged on the sides or lateral faces of the casing makes these units particularly suitable for their installation in false ceilings. This is due to the fact that the casing can be designed with a height-adjusted shape to fit into the false ceiling, at the same time that the areas located laterally to the unit are released, facilitating the installation of the corresponding air ducts, as well as electrical and/or electronics connections to connect to the unit.
  • Known controlled mechanical ventilation units of this type comprise a plurality of air inlets and one air outlet. Normally one of the air inlets has a larger diameter than the rest of the air inlets, the air inlet of larger diameter being designed to ventilate the kitchen of homes, since the required ventilation thereof is more demanding than for the rest of the rooms, for which all or some of the other air inlets are used.
  • the air inlets that are not used in the installation are closed or covered.
  • the object of the present invention is to provide a controlled mechanical ventilation unit that makes it possible to overcome the drawbacks that currently existing solutions present, as described.
  • the invention provides a mechanical ventilation unit that is versatile, compact, efficient in operation and simplified in installation.
  • the present invention provides a controlled mechanical ventilation unit comprising a casing.
  • the casing is polygonal prismatic in shape, i.e., it comprises a plurality of sides, preferably straight, that define the contour of the casing and two bases, front and rear, preferably flat.
  • the casing houses a centrifugal fan to move air from a plurality of air inlets to one air outlet. Said air inlets and air outlet are transversely arranged on the sides of the casing, i.e., going through said sides, and aligned according to a direction parallel to the bases of the casing. This configuration of the unit makes it easy to install the unit in narrow spaces such as false ceilings in homes.
  • the air inlets and the air outlet are able to be connected, directly or by means of connectors, to respective air ducts of the ventilation installation.
  • the air inlets that are not used can be selectively closed by means of at least one air inlet cover, each cover closing a selected air inlet.
  • the air inlet covers can be placed on or removed from selected air inlets to respectively disable or use the corresponding air inlet by leaving it closed or open.
  • the air inlet covers may be separate parts of the casing that are able to be connected to the casing to close the corresponding inlet, for example, by threading the cover around a mouth of the air inlet or by snapping the cover onto the mouth.
  • the unit may comprise the air inlet covers, for example, the covers being supplied with the same unit, or the covers being supplied separately.
  • the air inlets that are not going to be used can be closed, making it possible for one same unit to be used for different ventilation configurations in different homes.
  • the same ventilation unit can be used to ventilate homes with a different number of rooms, corresponding to each of the air inlets of the unit.
  • the controlled mechanical ventilation unit comprises a plurality of air inlets of larger diameter and a plurality of inlets of smaller diameter, the latter having a smaller diameter than the former. Additionally, the air inlets of the unit are arranged on the sides of the casing such that, between two air inlets of larger diameter and laterally to said two air inlets on one same side, a plurality of air inlets of smaller diameter are arranged.
  • the unit comprises a plurality of air inlets of smaller diameter between said inlets of larger diameter around the casing, on at least one of the two possible sides between the two inlets of larger diameter, according to each of the two possible path directions around the casing from one of said inlets.
  • the air inlet of larger diameter (normally intended for the kitchen in a home) that is of interest can be selected from among said two air inlets of larger diameter depending on the location of the air outlet, disabling the other air inlet by closing the same by means of an air inlet cover of larger diameter.
  • said two air inlets of larger diameter between which a plurality of air inlets of smaller diameter are arranged are arranged on respective sides of the casing that are facing each other. Facing sides are understood, in a plan view, as those where for each of the two facing sides, at least one of the lines perpendicular to the side drawn by one of the two vertexes thereof intersects with the opposite side.
  • the sides that are facing each other may further be substantially parallel to each other and/or substantially have the same length (plan view).
  • the casing comprises a plurality of pairs of sides that are facing each other, which further facilitates the connection to all the air inlets.
  • the sums of the diameters of the air inlets on the respective sides of at least one of said pairs of facing sides are the same and, more particularly, that all the air inlets arranged on the respective sides of said pair of facing sides are of equal diameter and the respective sides have the same number of air inlets.
  • this configuration enables the unit to be installed for a wide variety of room layouts and ventilation requirements by having a variety of conveniently distributed air inlets of different diameters, facilitating the connection of the corresponding air ducts, as well as electrical and/or electronic connections.
  • the air inlets are conveniently distributed around the centrifugal fan, which provides a more homogeneously distributed air flow towards the fan and therefore more adequate operation of the unit regardless of the rooms that are ventilated.
  • the sides adjacent to at least one of the sides where the two air inlets of larger diameter are arranged form obtuse angles with this side, i.e., interior angles of the polygon formed by the casing of more than 90°.
  • obtuse angles i.e., interior angles of the polygon formed by the casing of more than 90°.
  • the unit is exclusively provided with one air outlet, although it is not ruled out that it may have more than one air outlet.
  • the air inlets of the unit may have exclusively two different diameters, that all the sides of the casing may be facing each other two by two and/or that the casing may comprise more than two pairs of facing sides.
