Description

Panels for air handling unit modules, air handling units comprising such panels Meta-module and air handling unit comprising such a module

The invention relates to a panel for a module of an air handling unit. The invention also relates to a module of an air handling unit comprising such a panel and an air handling unit comprising such a module.

In the field of air treatment, it is known to use air-handling units consisting of a series of modules, each module comprising components related to the air-handling function. Each module comprises four, five or six surfaces, each composed of assembled panels. The faceplates of the modules must ensure satisfactory airtightness in order to reduce or eliminate thermal bridges between the interior and exterior of the unit.

In this matter, it is known, for example, from EP-A-2 578 959 to use a panel comprising an outer sheet, an inner sheet and a layer of insulating material sandwiched between the sheets which are then pressed against each other with minimal force. However, due to the positive or negative pressure generated inside the unit by the ventilation unit, the inner panel of the panel can undergo deformation, resulting in deformation of the insulation and the outer panel. Such deformations may lead to infiltration or parasitic air leaks which are detrimental to the correct operation of the air handling unit.

More specifically, the purpose of the present invention is to overcome this disadvantage by proposing a novel panel for a module of an air handling unit, the outer panels of which are not subject to deformation and thus ensure airtightness. Furthermore, deformation of the outer panels is perceived by the user as a defect of the unit. This creates a bad image for the producers of the unit.

In this spirit, the invention relates to a panel for a module of an air handling unit, said panel defining a main axis perpendicular to its surface and comprising an outer panel, an inner panel and an insulating material arranged between the outer and inner panels Between the layers, the plate and the layers are parallel to each other and perpendicular to the main axis of the panel. According to the invention, a gap having a thickness parallel to the main axis of the panel is defined between the layer made of insulating material and at least one of the outer and inner panels, said thickness being greater than or equal to 10 mm.

Through the gap created by the invention, deformation of the inner plate caused by positive or negative pressure does not lead to deformation of the outer plate. Such panels eliminate infiltration or parasitic air leakage due to deformation and improve the perceived quality of the unit.

According to an advantageous but not essential aspect of the invention, such a panel comprises one or more of the following characteristics considered in any technically acceptable combination:

- said gap is defined between the layer made of insulating material and the inner panel.

- said gap is defined between the layer made of insulating material and the outer panel.

- said outer panel and said inner panel are each provided with an edge, and the edge of at least one of said outer panel and said inner panel is oriented parallel to the main axis of the panel and towards the other panel.

- The edge of the outer panel is pressed against the edge of the inner panel perpendicularly to the main axis of the panel.

- A gap having a thickness perpendicular to the main axis of the panels is defined between the edges of the outer and inner panels and the layer made of insulating material.

- the panels comprise joint elements made of polymer material arranged around a layer made of insulating material and inserted along the main axis between the outer and inner panels, the edges of which are respectively arranged at into the recess of the engagement element.

- Outer and inner panels are made of metal.

The invention also relates to a module of an air handling unit, said module comprising several surfaces, at least one of which consists of a panel as described above.

Finally, the invention also relates to an air handling unit comprising a plurality of modules and a plurality of components, each module comprising components, said components being a ventilation unit, a heating battery and/or a cooling battery, at least one filter, a movable plate Strip louvers, heat recovery unit and humidification unit, said unit being characterized in that at least one module is as described above.

The ventilation unit is configured to move or ventilate the air handled by the unit 1 . The ventilation unit works by means of an electric fan unit comprising one or more electric motors equipped with one or more turbines.

The heating cells are configured to effect heating of the air treated by the unit 1 . In a heating cell, for example, a heat exchange fluid such as water or gas circulates. Furthermore, the heating of the air is ensured, for example, by means of one or more electric resistors or a gas boiler.

The cooling battery is configured to effect cooling of the air treated by the unit 1 . In cooling the battery, a heat exchange fluid circulates, such as water or a refrigerant liquid, for example.

The filter is configured to perform filtration of the air treated by the unit 1 . The filter used depends on the application of the unit 1.

The shutters with movable slats are configured to implement the closing and opening of one or more air circuits of the unit 1 . Their function is to enable or prevent the passage of air as required.

The heat recovery unit is configured to recover thermal energy of the air treated by the unit 1 . The recuperator unit then comprises, for example, regenerators such as plate regenerators, rotary regenerators, thermodynamic regenerators, heat pipes or saccharified water batteries.

The humidifier is configured to condition the humidity of the air treated by the unit 1 . Humidifiers include, for example, systems for spraying water in the form of water droplets or steam in order to ensure humidification of the air.

The module 2 of the air handling unit 1 comprises several surfaces 4 . In particular, the modules 2 shown in FIG. 1 comprise four or five surfaces 4 depending on their position in the unit 1 . The surfaces 4 are each composed of panels 6 .

As shown in Figure 2, each panel 6 defines a main axis X6 perpendicular to its surface. Furthermore, each panel 6 comprises a first plate 8, a second plate 10 and a layer 12 made of insulating material.

The panel 8 is also called an outer panel, since it is located on the outside of the air handling unit 1 . The panel 10 is also called the inner panel, since it is located inside the unit 1 .

The outer panel 8 is provided with four folded edges 14 . In particular, the folded edge 14 of the panel 8 is parallel to the main axis X6 of the panel 6 and oriented towards the inner panel 10 .

The inner panel 10 is provided with a folded edge 16 . The folded edge 16 is parallel to the main axis X6 of the panel 6 and is oriented towards the outer panel 8 . Furthermore, the folded edge 16 comprises a folded portion 33 oriented perpendicular to the main axis X6 of the panel 6 and towards the center of the inner panel 10 .

In practice, the edge 14 of the outer panel 8 is pressed against the edge 16 of the inner panel 10 perpendicular to the main axis X6 of the panel 6 .

In a variant not shown in the figures, the edge 14 or 16 of a single of the outer panel 8 and the inner panel 10 is parallel to the main axis X6 of the panel 6 and oriented towards the other panel.

The plates 8 and 10 and the layer 12 made of insulating material are parallel to each other and perpendicular to the main axis X6 of the panel 6 . The outer panel 8 and the inner panel 10 are made of metal.

In a variant, the outer panel 8 and the inner panel 10 are made of polymer material.

A layer 12 of insulating material is configured to thermally isolate the panel 6 . In practice, the layer 12 is configured to reduce the transfer of heat from the inside towards the outside and from the outside towards the inside. For this purpose, the layer 12 consists of blocks of fibre, mineral, plant-based or synthetic foam, for example.

A layer 12 of insulating material is arranged between the outer panel 8 and the inner panel 10 . The layer 12 made of insulating material is firmly connected to the outer panel 8, for example by self-adhesive strips.

A gap 18 having a thickness e parallel to the main axis X6 of the panel 6 is defined between the layer 12 made of insulating material and the inner panel 10 .

D is used to designate the internal distance between the plates 8 and 10 measured parallel to the main axis X6. The distance D is between 25mm and 85mm, and is preferably equal to 50mm. Furthermore, E is used to denote the thickness of the layer 12 made of insulating material measured parallel to the main axis X6 of the panel 6 . In particular, the thickness E is smaller than the distance D, preferably equal to 40 mm. The thickness e of gap 18 is measured parallel to axis X6 and is greater than or equal to 10 mm. The distance D is equal to the sum of the thickness E and the thickness e.

Furthermore, a gap 20 having a thickness perpendicular to the main axis X6 of the panel 6 is also defined between the edges 14 and 16 of the plates 8 and 10 and the layer 12 made of insulating material. In other words, the gap 20 is defined perpendicular to the main axis X6 on both sides of the layer 12 made of insulating material.

Thus, the layer 12 made of insulating material has a reduced thickness compared to prior art products, and it can be described as a "thin insulator".

In a variant not shown in the figures, the gap 20 is limited only on the edges of the layer 12 of insulating material.

According to a second embodiment of the invention, as shown in FIG. 3 , the layer 12 made of insulating material is firmly connected to the inner panel 10 , for example by means of self-adhesive tapes. Thus, a gap 18 having a thickness parallel to the main axis X6 of the panel 6 is defined between the layer 12 made of insulating material and the outer panel 8 .

According to a third embodiment of the invention, as shown in FIG. 4 , the layer 12 made of insulating material is firmly connected to the outer panel 8 by tabs 21 . Thus, in addition to the gap 18 , a gap 19 is defined between the layer 12 made of insulating material and the outer panel 8 , having a thickness e parallel to the main axis X6 of the panel 6 . In practice, the positioning of the layer 12 defines two gaps 18 and 19 parallel to the main axis X6.

In a variant not shown in the figures, the layer 12 made of insulating material is firmly connected to the inner panel 10 by means of tabs.

According to a fourth embodiment of the invention, as shown in FIGS. 5 and 6 , each panel 6 comprises a joint element 22 made of polymer material arranged around the layer 12 made of insulating material and Inserted between the outer plate 8 and the inner plate 10 along the main axis X6.

The engagement element 22 comprises four profiles 24 having the same section but different lengths. The lengths of the profiles 24 depend on the panels 6 with which they are configured.

Thus, the four profiles 24 are arranged in the form of a rectangle and four corners are provided for fitting together the ends of the profiles 24 in order to fix the profiles 24 and to construct the joining element 22 . In this case, the panel 6 is rectangular, as can be seen in FIG. 1 . In practice, the panel 6 may be rectangular or square.

As shown in FIG. 5 , each engagement element 22 includes an outer perimeter 26 defining an enclosed volume V of the engagement element 22 . The joining element 22 also comprises reinforcing ribs 28 arranged inside the closed volume V. As shown in FIG.

The perimeter 26 of the engagement element 22 defines a first recess 30 and a second recess 32 . The first recess 30 receives the folded edge 14 of the outer panel 8 . The second recess 32 is perpendicular to the first recess 30 and partially receives the folded edge 16 of the inner panel 10 . In particular, the folded portion 33 of the folded edge 16 is arranged in the second recess 32 of the joining element 22 .

Furthermore, the engagement element 22 comprises both male 34 and female 36 assembly means. The male assembly means 34 are formed by protruding ribs, while the female assembly means 36 are formed by hollow grooves.

As shown in FIG. 6 , the protruding rib 34 of the engagement element 22 is configured to engage in a hollow groove 36 belonging to another panel 6 of another engagement element 22 of the same section. In particular, the hollow groove 36 of the engagement element 22 of the panel 6 of the first surface 4 receives the protruding rib 34 of the engagement element 22 of the panel 6 of the second surface 4 adjacent to the first surface 4 and perpendicular thereto.

The embodiments and modifications considered above may be combined to produce new embodiments.
