Ventilation assembly configurable for top openings and/or side openings
A modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith for exploitation in a ventilation device or system.
The present invention relates to a ventilation device which comprises a housing means as well as a number of inlet and outlet means, namely fresh air inlet means, exhaust or stale air inlet means, exhaust or stale air outlet means and fresh air outlet means. The present invention in particular relates to a ventilation device comprising an outer frame means (e.g. a housing) and ventilation components mounted to said frame (e.g. within a housing) configured so as to define air paths (e.g. internal air paths) for the exchange of sensible and/or latent heat between exhaust air (e.g. warm and/or moist air) taken from inside a building or enclosure and exterior fresh air (e.g. cool and/or dry air) which is drawn into the building or enclosure. These types of ventilation systems or devices are known.
It would be advantageous to have available a ventilation unit available with top and/or side ports without having to exploit two totally different platforms. This would allow much more flexibility in terms of its fabrication and installation.
It would be advantageous to have a ventilation unit which may be designed with airflow and a heat (or energy) transfer core disposed in such a position that with the same frame an air-exchanger may be configured with top ports and/or side ports simply by blocking off the side or top openings as the case may be and by rotating the internal blower(s) which are configured as part of a module that could for example be incremented (i.e. rotated) by 90 degrees.
It would in particular be advantageous to have an enclosure or housing for a modular blower combination assembly able to be configured so as to be able to be seated in relation to an interconnection element such that air may be expelled from the air outlet thereof in a first direction and as desired in relation to production needs be rotatable so as to be able to be seated in relation to the interconnection element such that air may be expelled from the air outlet thereof in a second direction transverse to the first direction.
Thus the present invention in accordance with one aspect provides a modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith,
said interconnection element configured for interconnecting said pair of modular blower sub-assemblies in juxtaposed (e.g. releasable) relationship in a respective first configuration and in a respective second configuration,
each of said modular blower sub-assemblies comprising blower means and an enclosure disposed about said blower means,
said blower means having an upstream side and a downstream side,
said enclosure comprising a pair of opposed faces interconnected by side wall means,
said enclosure having an axis of rotation relative to said opposed faces,
one of said opposed faces defining a blower opening in air communication with one side of the blower means, the blower means having an axis of rotation transverse to said one opposed face,
said side wall means defining a side blower opening in air communication with the other side of the blower means,
said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass through said side blower opening in a first direction and being configured to be able, on rotation of the enclosure about said axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass through said side blower opening in a second direction transverse (e.g. perpendicular) to said first direction.
The present invention in accordance with another aspect provides a modular blower assembly for association with an interconnection element configured for (releasably) interconnecting a pair of modular blower assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration, said modular blower assembly comprising blower means and an enclosure disposed about said blower means,
said blower means having an upstream side and a downstream side,
said enclosure comprising a pair of opposed faces interconnected by side wall means,
said enclosure having an axis of rotation relative to said opposed faces,
one of said opposed faces defining a blower opening in air communication with one side of the blower means, the blower means having an axis of rotation transverse to said one opposed face,
said side wall means defining a side blower opening in air communication with the other side of the blower means,
said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass through said side blower opening in a first direction and being configured to be able, on rotation of the enclosure about said axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass through said side blower opening in a second direction transverse (e.g. perpendicular) to said first direction.
An enclosure for a modular blower assembly of the present invention may take on any form or configuration keeping in mind the requirement that the enclosure of a sub-assembly is to be able to be rotatable so as to displace the side wall opening as desired. An enclosure for a modular blower assembly may for example have a cross-section (transverse to the axis of rotation of the enclosure) which is square like (see figures below) so that the enclosure side wall elements may be rotated in incremental fashion (i.e. 90 degrees per rotation). The enclosure may however have any other type of cross-section keeping in mind the enclosure is to be able to pass from one configuration to another as described herein; it may have a hexagonal cross section. Alternatively, for example although the enclosure has been described in relation to a rectangular box-like form, the enclosure may take on a circular form (i.e. circular cross section relative to the axis of rotation of the blower means) in which case the interconnection element is to be modified in order to be able to displace the side wall opening as discussed herein.
Thus the present invention in accordance with another aspect provides a modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith,
said interconnection element configured for interconnecting said pair of modular blower sub-assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration,
each of said modular blower sub-assemblies comprising blower means and an enclosure disposed about said blower means,
said blower means having an upstream side and a downstream side,
said enclosure having a rectangular box-like form and comprising a pair of opposed square broad faces interconnected by a first side wall element and three secondary side wall elements, said enclosure having a central axis of rotation relative to said opposed square broad faces,
one of said opposed broad faces defining a blower air intake opening in air communication with the upstream side of the blower means, the blower means having an axis of rotation transverse (e.g. perpendicular) to said one opposed face,
said first side wall element defining a side blower air outlet opening in air communication with the downstream side of the blower means,
said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass out of said side blower opening in a first direction and being configured to be able, on rotation of the enclosure 90 degrees about said central axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass out of said side blower opening in a second direction perpendicular to said first direction.
The present invention in accordance with a further aspect provides a modular blower assembly for association with an interconnection element configured for interconnecting a pair of modular blower assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration,
said modular blower sub-assembly comprising blower means and an enclosure disposed about said blower means,
said blower means having an upstream side and a downstream side,
said enclosure having a rectangular box-like form and comprising a pair of opposed square broad faces interconnected by a first side wall element and three secondary side wall elements, said enclosure having a central axis of rotation relative to said opposed square broad faces,
one of said opposed broad faces defining a blower air intake opening in air communication with the upstream side of the blower means, the blower means hsving sn axis of rotation transverse to said one opposed face,
said first side wall element defining a side blower air outlet opening in air communication with the downstream side of the blower means,
said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass out of said side blower opening in a first direction and being configured to be able, on rotation of the enclosure 90 degrees about said central axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass out of said side blower opening in a second direction perpendicular to said first direction.
In accordance with the present invention the axis of rotation of the (blower) enclosure may be coterminous with the axis of rotation of the blower means enclosed therein; alternatively as desired or necessary the axis of rotation of the (blower) enclosure may be offset with respect to the axis of rotation of the blower means enclosed therein. The axis of rotation of the (blower) enclosure may be parallel or as desired or necessary non-parallel to the axis of rotation of the blower means enclosed therein. The axis of rotation of the( blower) enclosure may be considered to be a central axis or a non-central axis depending on the shape of the enclosure. In any event the disposition of these two axii of rotation is to be determined keeping in mind the requirement that the enclosure of a sub-assembly is to be rotatable so as to be able to displace the side wall opening as desired herein.
The interconnection element may take on any form or configuration keeping in mind the requirement that the enclosure of a sub-assembly is to be rotatable so as to be able to displace the side wall opening as desired. The interconnection element may for example comprise two or more components. The interconnection element may for example form a part of the outer enclosure of the ventilation unit. A modular blower combination assembly in accordance with the present invention may for example comprise an interconnection element which may comprise an elongated element which may have an L-like cross-section so as to have a foot portion and a upstanding leg portion connected thereto, said foot portion being configured for seating said enclosure by engagement with a secondary side wall element. An interconnection element which may, for example, comprise a shell element as described herein
In accordance with the present invention a ventilation device or system may incorporate therein modular blower sub-assemblies as described herein. The ventilation unit may for example also comprise a hexagonal shape stacked core such as described in published Can. Pat. Appln. No.2416508 and in U.S. patent application No. 739,412 published under no. 20040226685 the entire contents of both of which are incorporated herein by reference.
A ventilation unit in accordance with the present invention may have the heat exchanger Core laid on its back with only a slight angle to achieve enough water drainage. In this case the modular blower combination assembly may provide two blowers to get both exhaust blowers behind the core, i.e. on the air output sides of the core for exhausting air out of the fresh air and stale air sides of the core. Those blower enclosures may be if so desired identical (or different) and may be provided with a tongue and groove pattern for engagement with other elements of the ventilation unit, i.e. so that the enclosures may be rotated during production to achieve either a side or a top port configuration for the final ventilation unit.
In accordance with the present invention ventilator housing means may be provided which may be designed or configured with dual openings on each opposed sides as well as a pair of openings on the top side thereof. Any not-required openings may be blocked with a suitable respective plug; for example, any suitable “swappable” plug may be used to allow air circulation for either a side or a top port configured unit.
Benefits of a ventilation unit of the present invention include convertibility (e.g. at the factory, on the production line) of ventilation unit from top to side port (or vise-versa) while for example being relatively extremely flat (only 12 inches for a 100 Cfm (cubic feet per minutes) unit.
