Description

Title of the invention: Distributor element of heat recovery device

[0001] SUBJECT OF THE INVENTION

[0002] The invention, distributor element of individual heat recovery device and / or single-family extractor, refers to a distributor element or coupling piece which, intended for heat recovery systems or single-flow systems with multiple distribution, has a structural configuration specially designed for its integrated incorporation into the own individual heat recovery device or single-family extractor, in particular in the corners thereof, specially adapted for this purpose, allowing the various semi-rigid distribution ducts to be connected directly to the body of the heat recovery device or single-family extractor, so as to reduce the number of parts and the pressure loss of the system, which, among other advantages, improves performance, simplifies and reduces the cost of the installation.

[0003] Furthermore, preferably, the distributor element of the invention has a variable number of initially blind connection holes and is composed of a part with means of rapid fixing, preferably by tight adjustment, on the recuperator, so that it is of an easily interchangeable nature to be able to choose, according to the needs of each installation, the number of connections it will have. The connection of the distributor element with the semi-rigid conduit guarantees an adequate level of sealing.

[0004] The field of application of the present invention falls within the building sector dedicated to the manufacture and installation of controlled mechanical ventilation solutions, both double and single flow, covering both heating, ventilation and air conditioning systems as well as industrial, domestic or industrial process ventilation systems which generate residual heat.

[0005] BACKGROUND OF THE INVENTION

[0006] An individual heat recovery unit is a device intended to recover the heat extracted from heated extraction rooms, and to transfer it to the fresh air which is introduced into the intake rooms, thus increasing energy efficiency and reducing energy consumption. Its main function is to transfer heat from an air flow to an air flow, so as to take advantage of the thermal energy and reduce heat losses. In addition, the use of an individual heat recovery unit allows clean and filtered air to be introduced into the dwelling, since it has filters at the fresh air inlet and at the stale air outlet.

[0007] Usually, the heat recovery unit, to allow hot air and cold air to flow through the interior in a controlled manner to achieve heat transfer, has two air inlets, one with hot air and one with cold air, and two air outlets, one with hot air and one with cold air. When the heat recovery unit is applied in a multiple distribution system, which is generally the most common, to convey the air flow to several rooms or different points of an installation, an extension duct is coupled at the aforementioned hot and cold air outlets of the device, to which, at its distal end, an independent distribution box is incorporated into the heat recovery unit to which, moreover, the impulse and extraction networks are coupled which from there convey the flow to each of the different rooms or outlet points of the installation.

[0008] On the other hand, in a single-family extractor, only the stale air is mechanically extracted from the home or industry, without introducing new air or recovering heat from the extracted air. This extractor or ventilation box may also have a distribution box where the extraction ducts are coupled.

[0009] All of the above implies that the installation includes a high number of additional parts which, in addition to increasing the cost thereof, both in parts and labor, can cause a loss of efficiency, due to the fact that the air flow loses its temperature when passing through the extension tubes and the body of the distribution boxes, since these constitute spaces through which the air passes and expands before being distributed to the different outlets and where it is no longer heated or cooled.

[0010] The objective of the present invention is, therefore, to provide a practical solution to avoid said loss of efficiency, reduce the number of parts and elements of the installation and, at the same time, reduce the complexity of the installation, by means of the development of a distributor which is joined directly to the body of the heat recovery unit or single-family extractor, making it possible to directly connect all the distribution ducts of the air flow to the different outlets of the installation to the heat recovery unit or single-family extractor.

[0011] EXPLANATION OF THE INVENTION.

[0012] The present invention relates to a distributor element for a heat recovery device or single-family extractor. Thus, the distributor element consists of a part intended for controlled mechanical ventilation devices with multiple distribution (double or single flow), in particular for heat recovery devices or single-family extractors, and has a structural configuration designed for its coupling to a heat recovery device or single-family extractor, fixed in particular to the angles of the body or casing, of a heat recovery device or a single-family extractor, adapted for this purpose, making it possible to be able to directly connect the various distribution ducts of the installation to said mechanical ventilation device.

[0013] By means of the element which is the subject of the invention, we obtain: - reduction in the number of installation parts, since the extension conduit and distribution boxes and their accessories are avoided, - reduction of the complexity of the installation, due to the fact that the installation of the aforementioned extension tubes and distributor collector accessories is not necessary, - reduction of the system pressure loss, since the conduits are connected directly to the body of the heat recovery unit, which also improves the system's performance.

[0014] On the other hand, it is important to note that, preferably, the distributor element, which comprises a variable number of connection holes, at least one, is formed of a piece with two right-angled walls, with coupling or pressure fixing means, for its pressure fitting into the recuperator, thus facilitating the exchange of the distributor element to be able to choose, according to the needs of each installation, the number of connections, or conduits, which are necessary according to the installation. The piece thus has an external part and an internal part, close to the mechanical ventilation device once the distributor element is coupled to the device. These coupling means also allow the uncoupling of the distributor element from the heat exchanger device.Said holes have a specific diameter for the introduction into them of the pressure distribution pipe or conduit, guaranteeing the sealing of the connection between the pipe or conduit and the distributor element.

[0015] Preferably the holes are closed, thus determining blind holes, but are delimited by marks on the right-angled walls which determine their diameter so that the installer can open as many holes as necessary. Said marks are preferably made on the body of the distributor element by means of a circular groove, which when pressed gives access to the hole which thus becomes a through hole. Thus, the holes are through but can be closed on one of its sides so that the installer can choose the hole or holes to be uncovered for its use. The distributor element can therefore have all its holes open on both sides or at least one hole open on two sides and the other holes closed on one side or all the holes closed on one of its sides. The hole can be covered both on its external part and on its internal part, although it is preferable that it is covered on its external part.

[0016] Optionally, one or more of the different connection holes of the distributor element which is the subject of the invention may be closed by means of covers provided for this purpose. effect in the case where the connection of distribution conduits to each of them is not necessary.

[0017] In particular, the part that constitutes the distributor element for heat recovery devices or single-family extractors has a right-angled body with two walls that are joined perpendicularly on one of its sides, namely, has an L-shaped body defined by respective rectangular housings, which are joined perpendicularly and integrally to each other on one of their sides. These walls or housings each comprise several through holes, at least one and preferably three, which are suitable for receiving, through the external part of the part, the end of the distribution pipes of the installation.In the internal part of the part, it has the aforementioned quick coupling or fixing means on one of the corners of the casing of a heat recovery device, corner which, moreover, includes the air outlet of the recovery device and has a complementary configuration to receive said fixing means.

[0018] As mentioned, the through holes may be closed on the outer part and have markings, preferably a circular groove that determines a circle, which the installer can remove by pressure, thus giving access to the through hole. The pressure distributor conduit is introduced through this outer part of the hole.

[0019] Preferably, a distributor element which is the subject of the invention is fixed on one corner of the heat recovery unit or single-family extractor with the supply air outlet and another on another corner with the stale air outlet. Thus, the distributor element makes it possible to connect up to 6 distribution ducts directly to the device at the supply air outlet and six to the stale air outlet.

[0020] Preferably, the means for coupling or quickly fixing the part comprise a pressure-fit fixing tab which projects perimetrically on the internal part of the square part, said tab being sized to fit perfectly into a step-shaped recess of a hole provided in the corner of the recuperator casing.

[0021] Optionally, as mentioned, the part that makes up the distributor element comprises one or more covers to close one or more of the through holes of one or both walls or housings, in the case where it is not necessary to use all the holes for the connection of a distribution pipe.

[0022] The dispenser element is preferably made of high-density expanded polyurethane because this material meets the ideal conditions of use of the dispenser.

[0023] The distribution element when coupled to the heat recovery device or single-family extractor composes an air distribution system composed of the air recovery device or the single-family extractor with its casing and at least one corner, preferably two, and a distribution element conforming to the characteristics described above.

[0031] In view of the figures mentioned, the distributor element for a heat recovery device object of the invention, comprises a part (1) with a structural configuration intended for its integrated incorporation in the casing (10) of the heat recovery device itself, allowing the direct connection of multiple distribution conduits (5) of the installation. Said element is preferably made of high density expanded polyurethane

[0032] For this, preferably, the distributor element comprises a right-angled part (1) composed of two walls connected perpendicularly on one of its sides (3), namely, the part is formed of a body in the shape of a plantar L defined by two housings respective (2) rectangular joined perpendicularly and jointly on one of their sides (3). This joining side (3) preferably has a sharp or rounded edge.

[0033] Furthermore, each of the two perpendicular walls or boxes (2) comprises at least one through hole (4), preferably three, from an external part (1a) to an internal part (1b) of the right-angled piece (1). Each of these holes (4) is adapted to receive, via the external part (1a), one end of a distribution pipe (5) of the installation.

[0034] As can be seen in the figures, the internal part (1b) of the part (1) has means for quick coupling or fixing (6), and uncoupling, to a corner (10a) of the casing (10) adapted for this purpose to the heat recovery device in correspondence with its cold air outlets (101) or hot air outlets (102).

[0035] Preferably, said quick coupling or fixing means (6), and uncoupling, of the distributor (1) comprise a pressure-fitting fixing lug (60) which projects perimetrically on the internal part (1b) of the body or walls (2) in the form of a right angle. Said lug (60) is dimensioned to fit snugly into a step-shaped recess (103) provided in a space (104) of the at least corners (10a) of the casing (10) of the recuperator where the cold air (101) and hot air (102) outlets converge.

[0036] Preferably, said quick coupling or fixing means (6) of the distributor (1) are removable, thus allowing the distributor (1) to be of an interchangeable nature, namely, allowing the latter to be uncoupled from the recovery device.

[0037] Optionally, the distributor (1) comprises one or more covers (not shown) for closing one or more of the through holes (4) of the perpendicular housings (2) when these are not necessary for the connection of distribution pipes (5).

[0038] Looking at Figures 3 and 4, we can see how, according to the invention, a single-family extractor device for which the distributor element object of the invention is intended comprises a casing (10) composed of a parallelepiped body of square plan (Figures 3 and 4) or rectangular (individual heat recuperator) ([Fig.5]). , inside which the different functional elements of the device are housed, being formed by an upper base (10b), a lower base (10c), and a lateral partition (10d) with, at least, two corners (10a) provided with interstices (104) in which converge, respectively, the cold air outlet (101) and the hot air outlet (102) where the respective parts (1) which make up the distributor element fit.

[0039] Furthermore, in another embodiment, such as that shown in [Fig. 5], the side partition (10d) of the housing (10) of the heat recovery unit comprises four corners (10a) provided with holes (104), two of which the cold air outlets (101) converge. and the hot air outlets (102) where the respective parts (1) of the distributor fit and two others in which the cold air inlet (105) and the hot air inlet (106) converge, suitable for receiving the respective coupling parts (100) in the shape of a square, or L, with a single through hole (4) for the connection of the corresponding air inlet tube (7).

[0040] Finally, looking at [Fig.6], we can observe how, according to the prior art, in multiple system applications, to the cold (101) and hot (102) air outlets of the casing (10') of a conventional heat recovery unit are coupled extension tubes (8) to which are incorporated, at their opposite end, respective independent collector-distributor accessory devices (9) to which, moreover, the various distribution conduits (5) are coupled.
