Definitions

• the present invention relates, in a general manner, to the technical field of plant walls. It relates, more specifically, to a plant wall with internal air circulation.
• Each rack of such a structure has a frame, which supports meshed or meshed faces, in particular meshed and meshed front and rear faces.
• the bins are filled with a planting substrate, such as potting soil which, in the case of a perforated configuration of the faces through which these bins are made adjacent, can extend without interruption within the structure of the plant wall.
• a planting substrate such as potting soil which, in the case of a perforated configuration of the faces through which these bins are made adjacent, can extend without interruption within the structure of the plant wall.
• a network of water pipes and also a network of air tubes which extend in the thickness of the different juxtaposed and / or superimposed bins, so inside planting substrate filling these trays, crossing the horizontal and / or vertical joint planes between adjacent traps.
• the lower, upper and lateral faces of the bins being perforated, they allow the free passage of the air and water networks, from a locker to an adjacent rack, without the need for drilling or installation of special fittings, which facilitates the manufacture and implementation of the structure of the plant wall.
• the air network makes it possible to circulate polluted external or internal air, pulsed by a pump, to depollute this air in contact with the planting substrate, by a filtration effect to which is added a bacterial action according to the principle of biofilter. Obtaining such an operation assumes, however, that the air to be decontaminated is optimally removed in the planting substrate. In addition, in order to maintain an advantageous energy balance, the air must be diffused into the substrate with minimal energy consumption.
• the diffusion of air into the planting substrate is obtained by perforations provided in the air tubes.
• This solution certainly simple, does not provide a good distribution of air in the whole of a locker.
• a portion of the substrate is saturated with polluted air, while the volume of the trap keeps areas in which the air hardly reaches.
• the bad distribution of the air leads to an inefficiency of the function of depollution of this air.
• the distribution of air pulsed through perforations in the air tubes requires a relatively high power, so a large pump and very energy-consuming, delivering a high pressure that does not optimize the time of stay of the air in the substrate.
• the increase in the passage section of the perforations is not a suitable solution, because it entails a risk of penetration of the substrate into the air network, with the consequence of a risk of clogging of the air tubes, therefore a result which would be the opposite of what we want.
• the present invention aims to remedy the disadvantages previously described, and is therefore intended to provide, for a plant wall of the kind considered here, an internal air diffusion system that is more efficient, particularly a system spreading the air homogeneously in the bins, so in the planting substrate, so as to improve the depollution of this air, while increasing the energy efficiency.

• the invention provides for the replacement of the perforated air distribution tubes with a plenum, which allows a distributed and homogeneous distribution of the air in each cell of the green wall, and therefore in the substrate. plantation filling this trap.
• the distribution of air through a window or grid of large section also allows a relatively slow diffusion of this air, optimizing the residence time of the air in the substrate for a more effective depolluting action, while by providing a saving of energy consumption necessary for the operation of the pump.
• the air diffusion window or grid may include a porous membrane through which air is diffused to the planting substrate, further slowing the flow of air while preventing undesirable entry of the substrate to the substrate. inside the plenum.
• each air distribution plenum, associated with a rack is fixed vertically to the frame of the rack, which ensures its precise positioning and its retention in place, even in the absence of substrate.
• the air diffusion grid contributes to the rigidity of the plenum and the assembly.
• each air distribution plenum is advantageously arranged vertically on the rear face of the corresponding bin, the plenum itself having a full back face and a front face with window or air diffusion grid.
• each air distribution plenum may, on the contrary, be arranged vertically at mid-thickness of the corresponding rack, so equal distance of the front and rear of the bin, the plenum itself having a front face with window or air diffusion grid, and a rear face also with window or air distribution grid.
• the only front face or the front and rear faces of the air distribution plenum include a peripheral zone outside the air distribution window or garrel. full. This zone can be rigid or more or less flexible.
• the solid peripheral zone has a constant width, on all sides of the window or air diffusion grid, so that this window or grid has a position centered on the plenum, therefore also in the locker.
• the area Full device has, above the window or air diffusion grid, a height greater than its height below the window or air diffusion grid.
• the window or grid remains centered relative to the substrate, despite the settlement of the latter.
