    DETAILED DESCRIPTION
    As mentioned above, the subject of the invention is a mixing box 2 and the ventilation installation 1 which results from the combination of such a mixing box 2, in particular with a module 21 for blowing air. .
    Indeed, the mixing box 2, object of the invention comprises, in the example shown, two air inlets 3, 4 and two air outlets 5, 6 with one of the outputs shown in 5 and called first air outlet, intended here to be connected to an air blowing module 21 capable of blowing air into an enclosure 20 of a construction, in particular into the living space of such a construction .
    In a known manner, the air blowing module 21 comprises an insufflation chamber containing a fan. This fan operates permanently, and blows air via a network of ducts, in the enclosure 20 forming the living space of the building. The air inlet of the chamber of the air blowing module 21 is connected to the first outlet 5 of the mixing box 2. Generally, this air blowing module 21 and the associated mixing box are arranged in the attic of the building, the enclosure 20 of the building forming the living space arranged under the eaves. The construction thus equipped with such a ventilation installation is mechanically ventilated permanently, which ensures a permanent renewal of the air of the enclosure.
    The mixing box supplying air to the fan of the air blowing module 21 comprises, in the example shown, two identical elements 71, 72, assembled to one another in a contiguous manner. Each element comprises a chamber provided with three openings and a shutter member capable of selectively closing two of the openings. Thus, the element represented at 71 in the figures comprises a chamber 81 provided with three openings 91, 101, 111 and a shutter member 121 housed inside said chamber, while the element represented at 72 in the figures comprises a chamber 82 provided with three openings 92, 102, 112 and a closure member 122 housed inside said chamber.
    The chamber of each element is delimited by a polygonal body, in this case heptagonal and the openings are formed on distinct faces of the heptagon.
    In the example shown, the body of each element comprises a top face, a bottom face parallel to the face of the top, and side faces, in this case five side faces connecting the top and bottom faces between them. . The openings are formed on the side faces. The top and bottom faces are called above and below by convention, the element being able to rest by one of its lateral faces.
    The chambers 81, 82 communicate with each other by one of the openings called communication openings and represented in 91 for the element 71 and in 92 for the element 72. To allow such communication, the elements are connected to each other at this communication opening, as shown, or the communication openings of the elements are connected to one another by a sheath, not shown, which has the advantage to be able to separate the elements from one another and to dispose of them, for example in free places of the attic of the construction.
    In addition to this communication opening, the chamber of each element comprises, among its openings, two other openings able to form, one, an air inlet in the mixing box, the other an air outlet of the box. mixing. Thus, the opening 101 of the element 71 forms an air inlet 3 of the mixing box and the opening 111 of the element 71, an air outlet, in this case the first outlet 5 of air of the mixing box, while the opening 102 of the element 72 forms an air inlet 4 of the mixing box and the opening 112 of the element 72, an air outlet, in the occurrence the second air outlet 6 of the mixing box.
    In the example shown in FIGS. 1 to 4, this second air outlet 6 of the mixing box is equipped with means 22 for forced air circulation, towards the outside of the mixing box. These means 22 for forced air circulation are again formed by a fan that draws air contained at least in the chamber 82 of the element 72 of the mixing box, to reject it generally outside the construction. The air inlet 3 of the mixing box formed by the air inlet opening 101 of the chamber 81 of the element 71 is called the fresh air inlet, because the air fed into this inlet is usually taken outside the building. The air inlet 4 of the mixing box formed by the air inlet opening 102 of the chamber 82 of the element 72 is called the hot air inlet. Indeed, in the example shown, this air inlet is connected to the air knife disposed on the back of a thermal sensor 23, in this case, here, a photovoltaic panel. This photovoltaic panel is able to produce electricity for construction. This panel tends, during its operation, to heat, which results in the presence of a blade of hot air on the back of this photovoltaic panel. This hot air impairs the performance of said panel. To improve the efficiency, said photovoltaic panel is thus ventilated, and the air is therefore driven by the air blowing module 21 and / or the forced air circulation means 22 equipping the mixing box towards the airbox. mixing, thus allowing a renewal of this air in contact with the photovoltaic panel. This air can then be used for heating the construction, according to its fate at the outlet of the mixing box, as will be described below. Alternatively, the hot air inlet could have been connected to the back of an air solar collector via a hot air storage system.
    To allow the supply of the first air outlet of the mixing box, either with fresh air or with hot air, or with a mixture of fresh and hot air, the organs 121, 122 shutter are provided. In the example shown, each closure member 121, 122 is a pivoting flap mounted movably between two positions. The pivot axis here extends in each case perpendicularly to the undersides and the top of the polygonal body of said element. Thus, the member 121 for closing the element 71 is mounted to move between two extreme positions, namely a first position in which it closes the fresh air inlet 3 of the mixing box formed by the opening 101. of the chamber 81 of the element 71, and a second position in which it closes the opening 91 of communication of the chamber 81 of the element 71 with the chamber 82 of the other element 72. The body 122 of closure of the element 72 is movably mounted between two extreme positions, namely a first position in which it closes the second outlet of the mixing box formed by the opening 122 of the chamber 82 of the element 72, and a second position in which it closes the opening 92 of communication of the chamber 82 of the element 72 with the chamber of the element 71.
    Thus, one of said shutter elements is able to selectively close the communication aperture and the air inlet opening of the associated element, while the other shutter element is able to selectively close off the air outlet opening and the communication opening of the associated element. These shutter elements can each occupy a third position in which none of the openings of the chamber of the associated element is closed.
    Each shutter member may be associated with a control unit in pivotal displacement (not shown). This control unit may comprise a servomotor causing the pivoting movement of the flap according to parameters, such as the desired temperature of the building enclosure to be ventilated, the temperature of the fresh air, the temperature of the hot air, etc. This piloting will not be described because it is well known to those versed in this art.
    Thanks to the design of the elements as described above, the mixing box is able to have at least three operating configurations illustrated in Figures 1 to 4.
    Thus, in the first operating configuration shown in FIG. 1 and called summer configuration, the first air outlet 5 of the mixing box is supplied with air exclusively from the inlet 3 of fresh air. The second air outlet 6 of the mixing box is supplied with air exclusively from the inlet 4 of hot air of the mixing box, and the shutter elements each close the communication opening of the chamber. , inside which they are arranged. In this first configuration, the fan of the air blower module 21 and the fan of the forced air circulation means 22 are managed independently of one another. They work in parallel, without interfering with each other.
    In the second operating configuration shown in FIG. 2, the first air outlet 5 of the mixing box 2 is supplied with air exclusively from the inlet 4 of hot air. The closure member 121 closes the fresh air inlet 3 of the mixing box and the closure member 122 closes the second outlet 6 of the mixing box. The fan of the forced air control means 22 is at a standstill. Thus, all the hot air from the back of the photovoltaic panel that reaches the mixing box is blown through the air blowing module in the enclosure of the construction, to allow the heating of said enclosure. It is thus possible to benefit from free calories for ventilation of the construction.
    In the third configuration, shown in FIGS. 3 and 4, the first air outlet 5 of the mixing box is supplied with air from a mixture of air flow coming from the inlet 3 of fresh air and from the entrance 4 of hot air. In the example shown in Figure 3, the shutter member 121 is positioned midway between the air inlet 3 and the opening 91 of communication and the shutter member 122 closes the second outlet 6 of the mixing box, and the fan means 22 forced circulation of air is stopped. In the example shown in FIG. 4, the closure member 121 is halfway between the air inlet 3 and the communication opening 91 and the shutter member 122 is also halfway between path between the communication opening 92 and the second air outlet 6 of the mixing box. This third configuration, with one or other of the versions, is used especially in mid-season, in the spring or in the fall, when the insufflation of the totality of the hot air resulting from the entry of hot air from the mixing box in the enclosure of the construction would cause too high temperatures inside said enclosure. Generally, either version is possible. Again, the management of the on / off operation of the means 22 for forced circulation of air can be operated using a control unit, in a manner known per se. The above example shows the potentialities of such a mixing box, it being understood that for simplified versions, it can be used a single element mixing box or on the contrary, for even more complex versions, boxes mixed with a number of elements greater than two.
