- the box-like body 10 for the vertical housing of an apparatus A for dual-flow mechanical ventilation with heat recovery which has just been described has excellent installation flexibility thanks to the possibility of defining different configurations for the transit of the introduction air flow I and of the extraction air flow E. Furthermore, the box-like body 10 is also easy and practical to install thanks to the presence of several fixing holes 58-61 and of a trimmable frame 62.
- Using an insulating material to make the box-like body 10 enables the energy efficiency of the apparatus A to be maintained regardless of the place of installation, in particular it ensures a great energy efficiency of the apparatus A housed internally even when the box-like body 10 is installed outside the room to be ventilated.
- the costs of the box-like body 10 according to the invention can be contained by making it in an insulating material that is inexpensive, for example by making it in PP.
- the box-like body 10 enables the apparatus A to be accessed easily if it is necessary to proceed with a maintenance task thanks to the fact that the hatch that is fitted to the box-like body 10, without or with slits, is removable or openable.

- The present invention relates to a box-like body for housing an apparatus for dual-flow mechanical ventilation with heat recovery of a closed room, for example of an apartment or an office, intended to be installed on a perimeter wall of a facade of a building covered with a thermal coat, in particular in a suitable recess of the wall, maintaining insulation continuity on the facade.
- In recent years, machines for dual-flow controlled mechanical ventilation with heat recovery (hereinafter referred to as VMC machines or more simply as VMCs) have entered our homes and offices to ensure the correct air exchange and the lowest possible energy expenditure.
- VMC machines, in particular, are normally installed inside the room to be ventilated.
- For internal installation, VMC machines are in some cases embellished in the form and in the optional, so much so that they become real furnishing elements for the interior, but this embellishment is reflected in the price.
- Further, VMCs can reach rather important dimensions that hardly adapt to today's building market which is significantly shifting towards the construction of multilevel buildings with many increasingly small apartments.
- It would therefore be desirable to find an alternative solution for installing VMC machines that maintains the energy efficiency of the VMC and which, at the same time, enables any required maintenance tasks to be performed easily thereupon.
- Further, it would be desirable for the alternative solution to have great simplicity and be practical to install, in combination with a great flexibility of installation and low cost.
- The main object of the present invention is to propose a box-like body for housing an apparatus for dual-flow mechanical ventilation with heat recovery, i.e. a VMC machine, which enables the VMC machine to be installed on a perimeter wall of a facade of a building.
- A further object of the present invention is that the aforesaid box-like body is very simple and practical to install, in combination with a great installation flexibility.
- A further object of the present invention is that the aforesaid box-like body has a low cost.
- A further object of the present invention is that the aforesaid box-like body preserves the energy efficiency of the VMC machine regardless of the place of installation, ensuring the continuity of insulation on the outer facade of the building.
- A further object of the present invention is that the aforesaid box-like body enables the VMC machine to be accessed easily if it is necessary to proceed with a maintenance work.
- These objects are achieved by a box-like body for vertical housing of an apparatus for dual-flow mechanical ventilation with heat recovery according to the first claim.

Fig. 9 is a perspective view of the box-like body ofFig.8 associated with the removable or openable hatch with slits ofFig.4 , the latter having a part removed to enable the apparatus housed inside the box-like body to be seen. - With reference to
Figs. 1-5 , the illustrated box-like body, indicated generically by 10, for housing in a vertical position an apparatus A for dual-flow mechanical ventilation with heat recovery, comprises ahousing seat 12, inside which the apparatus A is housed and at which air introduction/extraction chambers 13-16 are obtained, the latter being communicating with thehousing seat 12. - The box-
like body 10 is associable both with a removable or openable, for example by an hinge, hatch withslits 11A, shown inFigs.6-9 , and with a removable or openable, for example with an hinge,blind hatch 11B, shown inFigs. 1,2 . In particular, the removable or openable hatch withslits 11A has twoslits slits 64 with respect to the vertical housing direction, referred also as thelower slit 35, and the second obtained at an upper portion of the removable or openable hatch withslits 63 with respect to the vertical housing direction, referred also as theupper slit 34. - The air introduction/extraction chambers 13-16, as can be seen in
Figs.3,5 , have respective air introduction/extraction openings 17-28 to connect the box-like body 10 to a room to be ventilated and to an external environment. Further, as represented inFigs.5-9 , the box-like body 10 is provided withcanalizations 29 and passages 30-33, which are closed in an openable manner, to put the air introduction/extraction chambers 13-16 in communication with theslits like body 10 is associated with the removable or openable hatch withslits 11A. - The passages 30-33 closed in an openable manner can be for example passages closed by removable caps, or can be made by a predefined wall area suitable for being cut so as to be able to remove the wall area and, in this manner, open the passage. Similarly, the
canalizations 29 closed in an openable manner can be provided for example with removable walls, or can havewalls - The box-
like body 10 has doors 50-53 to put the air introduction/extraction chambers 13-16 in communication with thehousing seat 12. The doors 50-53, in particular, are aligned with respective air introduction/extraction openings of the apparatus A once the apparatus A has been housed inside thehousing seat 12. - In the embodiment represented in the figures, the number of air introduction/extraction chambers 13-16 is equal to the number of air introduction/extraction openings of the apparatus A, and is equal to the number of passages 30-33; in particular, the air introduction/extraction chambers 13-16 are four and each one has, respectively, one or more, for example three, air introduction/extraction openings 17-28 orthogonal to one another; more in particular, as can be seen in
Fig.5 , of the four air introduction/extraction chambers 13-16, two are upper, i.e. positioned at an upper portion of the box-like body 65 with respect to the vertical housing direction, whereas the other are lower, i.e. positioned at a lower portion of the box-like body 66 with respect to the vertical housing direction; thehousing seat 12 is arranged between the two upper chambers and the two lower chambers, i.e. between the upper portion of the box-like body 65 and the lower portion of the box-like body 66. - In detail, when the box-
like body 10 is associated with the removable or openable panel withslits 11A, the twopassages upper chamber 14 with theupper slit 34 and thelower chamber 15 with thelower slit 35, whereas the other twopassages canalizations 29, the otherupper chamber 13 in communication with thelower slit 35 and the otherlower chamber 16 in communication with theupper slit 34. As shown inFig.5 , thecanalizations 29 are provided with twowalls canalizations 29 from the secondupper chamber 13 and the other separating thecanalizations 29 from the secondlower chamber 16. - The box-
like body 10, as can be seen inFigs.3,5 , is provided withoutlets like body 10 to the outside or to enable the transit of a pipe to discharge the condensation, and withoutlets - In addition, as represented in
Fig.5 , the box-like body 10 is provided with atrimmable frame 62 in order to modify the depth h of the box-like body 10 itself so as to adapt the box-like body 10, for example, to the depth of a recess present on an outer perimeter wall of a room to be ventilated. - As shown in
Fig.3 , the box-like body 10 further features several fixing holes 58-61 to fix the box-like body 10 to a wall or a ceiling of a room, or to a facade of a building. Furthermore, the box-like body 10 is made of an insulating material, for example polypropylene (PP), so as not to degrade the energy performance of the house or the room to be ventilated if the box-like body 10, and thus the apparatus A, is installed outside, and so as to avoid dispersion of the VMC itself. - The box-
like body 10 thus made enables different passage configurations to be defined for an introduction air flow I and an extraction air flow E, generated by the apparatus A, with reference to the room to be ventilated and to the external environment, avoiding direct contact therebetween. - First of all, reference is made to the box-
like body 10 combined with the removable or openableblind hatch 11B, illustrated inFigs. 1,2 . In this case, as there are noslits canalizations 29 remain closed, and the connection of the box-like body 10 to the room to be ventilated and to the external environment is made only through the air introduction/extraction openings 17-28. - Depending on the geometry of the ventilation ducts, the air introduction/extraction openings 17-28 chosen for the connection are provided with respective removable ports 36-39, whereas the others are kept closed by removable caps 40-49. In particular, in the present exemplary embodiment, three different possible air introduction/extraction openings 17-28 are available for each air introduction/extraction chamber 13-16, enabling, in this manner, to choose the passage configuration of the air flows which is better suited to the ventilation ducts of the room to be ventilated.
- In this case, therefore, the paths that the introduction air flow I and the extraction air flow E follow inside the box-
like body 10 reflect those inside the apparatus A, as can be seen inFigs. 1,2 . - In particular, two different paths are possible for the air flows inside the box-like body 10: a first path, illustrated in
Fig.1 , in which the box-like body 10, and thus the apparatus A, is connected to the external environment via the twolower chambers upper chambers Fig.2 , in which, on the other hand, the box-like body 10 is connected to the external environment via the twoupper chambers lower chambers Fig.2 with respect toFig.1 . - When the box-
like body 10 is associated with the removable or openableblind hatch 11B, it is possible to install the apparatus A both inside and outside the room to be ventilated. In particular, by installing the box-like body 10 outside the room to be ventilated, only the ventilation ducts suitable for connecting the box-like body 10, and thus the apparatus A housed inside, to the room to be ventilated will be necessary, given the direct connection of the box-like body 10 with the external environment. - Otherwise, when the box-
like body 10 is associated with the removable or openable hatch withslits 11A, as illustrated inFigs.6-9 , the apparatus A can be arranged only outside the room to be ventilated because the connection with the external environment, made via the suitably opened passages 30-33 andcanalizations 29, is conveyed by theslits - The box-
like body 10 is, on the other hand, again connected to the room to be ventilated by the air introduction/extraction openings 17-28. In particular, depending on the geometry of the ventilation ducts, the air introduction/extraction openings 17-28 chosen for the connection are provided with respective removable ports 36-39, whereas the others are kept closed by removable caps 40-49. In particular, three different possible air introduction/extraction openings 17-28 are available for each air introduction/extraction chamber 13-16, enabling to choose the transit configuration of the air flows which is better suited to the ventilation ducts of the room to be ventilated. - Also in this case, two different paths for the air flows inside the box-
like body 10 are possible. In particular, the box-like body 10 can be connected to the room to be ventilated via the twoupper chambers 13,14 (which can be seen inFig.5 ), as illustrated inFigs.6,7 , or by the twolower chambers 15,16 (which can be seen inFig.5 ), as illustrated inFigs.8,9 ; nevertheless, the introduction air flow I must necessarily enter inside the box-like body 10 through theupper slit 34, whereas the extraction air flow E has to exit the box-like body 10 through thelower slit 35; for this reason, the paths that the introduction air flow I and the extraction air flow E follow inside the box-like body 10 do not reflect, in this case, those inside the apparatus A. - In particular, the first path illustrated in
Figs.6,7 should be considered, in which the box-like body 10 is connected to the room to be ventilated by the twoupper chambers 13,14 (which can be seen inFig.5 ). - In this case, the passages will be opened which, respectively, put the
lower chamber 15 in communication with thelower slit 35 and put thelower chamber 16 in communication with theupper slit 34, whereas the others will remain closed; moreover, thelower wall 68 which separates thecanalizations 29 from thelower chamber 16 will be cut out. - Doing so, the introduction air flow I enters inside the
upper slit 34 and flows through thecanalizations 29 to the secondlower chamber 16, through which it enters inside the apparatus A, whereas the extraction air flow E exits thelower slit 35 passing through thelower chamber 15. - Otherwise, now attention must be directed to the second path, illustrated in
Figs.8,9 , in which the box-like body 10 is connected to the room to be ventilated via the twolower chambers 15,16 (which can be seen inFig.5 ). - In this case, the open passages and the passages which remain closed are reversed with respect to the preceding case and the same thing happens for the
walls upper chamber 14 in communication with theupper slit 34 and theupper chamber 13 in communication with thelower slit 35, whereas theupper wall 67 which separates thecanalizations 29 from theupper chamber 13 is cut out. - In this manner, the introduction air flow I enters inside the
upper slit 34 and flows inside the apparatus A through theupper chamber 14, whereas the extraction air flow E, passing through theupper chamber 13, flows along thecanalizations 29 to thelower slit 35, through which it exits. - In conclusion, the box-
like body 10 for the vertical housing of an apparatus A for dual-flow mechanical ventilation with heat recovery which has just been described has excellent installation flexibility thanks to the possibility of defining different configurations for the transit of the introduction air flow I and of the extraction air flow E. Furthermore, the box-like body 10 is also easy and practical to install thanks to the presence of several fixing holes 58-61 and of atrimmable frame 62. - Using an insulating material to make the box-
like body 10 enables the energy efficiency of the apparatus A to be maintained regardless of the place of installation, in particular it ensures a great energy efficiency of the apparatus A housed internally even when the box-like body 10 is installed outside the room to be ventilated. - In addition, the costs of the box-
like body 10 according to the invention can be contained by making it in an insulating material that is inexpensive, for example by making it in PP. - Lastly, the box-
like body 10 enables the apparatus A to be accessed easily if it is necessary to proceed with a maintenance task thanks to the fact that the hatch that is fitted to the box-like body 10, without or with slits, is removable or openable. - Variants on the configuration of the box-
like body 10 and on the configuration and number of the components thereof are possible.
