Abstract

The system consists of a high-output fan (13) with fixing brackets at the top, and an air diffusor (15) with a raised centre (16) beneath it. The fan draws in air from above and blows it out sideways, creating a horizontal air flow at an optimum height, creating a movement of air at the level of the livestock, esp. poultry, by induction alone and with no direct contact between the air flow and the livestock. The system can also be equipped with mist nozzles to humidify the air flow and lower the air temperature experienced by the livestock.

Description

DISPOSITIF POUR AMELIORER LE CIRCUIT D'AIR DE VENTILATION
DANS LES BATIMENTS D'ELEVAGE.DEVICE FOR IMPROVING THE VENTILATION AIR CIRCUIT
IN LIVESTOCK BUILDINGS.

La présente invention concerne un dispositif pour améliorer la circulation de l'air dans les bâtiments d'élevage, particulièrement de type avicole.The present invention relates to a device for improving the circulation of air in livestock buildings, particularly of the poultry type.

Ces bâtiments sont conçus pour optimiser la croissance des animaux.These buildings are designed to optimize the growth of animals.

Les paramètres du bâtiment sont gérés de façon très pointue, afin de donner le meilleur compromis de confort aux animaux qui expriment ainsi au mieux leur potentiel de croissance.The parameters of the building are managed very precisely, in order to give the best compromise of comfort to the animals which thus express their growth potential as well as possible.

La maîtrise du renouvellement de l'air intérieur est très importante car ce paramètre doit évoluer en permanence en fonction de multiples données, à savoir : température de l'air intérieur et extérieur, taux d'humidité, nombre d'animaux, vitesse de l'air, etc ...Controlling the renewal of indoor air is very important because this parameter must constantly change based on multiple data, namely: indoor and outdoor air temperature, humidity, number of animals, speed of the air. , etc ...

Dans toutes circonstances le renouvellement d'air doit être suffisamment élevé pour éviter l'étouffement des animaux, tout en restant suffisamment bas pour éviter des courants d'air froid.In all circumstances the air renewal must be high enough to avoid suffocation of the animals, while remaining low enough to avoid cold drafts.

Il y a trois types de bâtiments d'élevage, suivant le type de renouvellement d'air - les bâtiments dynamiques font appel à un système de
ventilation pour forcer l'entrée ou l'extraction de l'air.There are three types of livestock buildings, depending on the type of air renewal - dynamic buildings use a system of
ventilation to force the entry or extraction of air.

- les bâtiments naturels utilisent la force du vent comme
élément de renouvellement d'air.- natural buildings use the force of the wind as
air renewal element.

- les bâtiments statiques utilisent l'effet de cheminée
pour assurer la ventilation.- static buildings use the chimney effect
to provide ventilation.

L'invention faisant l'objet de ce document concerne en priorité les bâtiments statiques, mais elle peut être utilisée dans les autres types de bâtiment.The invention which is the subject of this document relates primarily to static buildings, but it can be used in other types of building.

Pour les raisons expliquées plus loin, le renouvellement d'air de ces bâtiments devient insuffisant lorsqu'il fait chaud dehors.For the reasons explained below, the air renewal of these buildings becomes insufficient when it is hot outside.

Le dispositif selon l'invention permet de remédier à cet inconvénient, dans la mesure ou il permet de forcer le mouvement d'air à l'intérieur lorsque le fonctionnement normal devient insuffisant.The device according to the invention overcomes this drawback, insofar as it makes it possible to force the movement of air inside when normal operation becomes insufficient.

En option, le dispositif peut être équipé d'un système de brumisation pour baisser la température ressentie par les animaux. Optionally, the device can be equipped with a misting system to lower the temperature felt by the animals.

Les dessins en annexe illustrent l'invention.The accompanying drawings illustrate the invention.

La figure 1 représente une coupe transversale d'un bâtiment statique dans de bonnes conditions de fonctionnement, c'està-dire, lorsque la température intérieure est suffisamment supérieure à la température extérieure.Figure 1 shows a cross section of a static building in good operating conditions, that is, when the indoor temperature is sufficiently higher than the outdoor temperature.

La figure 2 représente une coupe transversale d'un bâtiment statique dans le cas ou les températures intérieures et extérieures sont très proches, mettant en évidence le problème de mauvaise ventilation.Figure 2 shows a cross section of a static building in the case where the indoor and outdoor temperatures are very close, highlighting the problem of poor ventilation.

La figure 3 représente une coupe transversale d'un bâtiment statique dans les conditions défavorables décrites pour la figure 2, mais équipée de l'invention.FIG. 3 represents a cross section of a static building under the unfavorable conditions described for FIG. 2, but equipped with the invention.

La figure 4 représente le détail de l'invention.Figure 4 shows the detail of the invention.

La figure 5 représente une vue horizontale de l'invention, avec les circuits d'air provoqués.FIG. 5 represents a horizontal view of the invention, with the air circuits caused.

La figure 6 représente le bâtiment de la figure 3, équipé de l'option de brumisation.Figure 6 shows the building in Figure 3, equipped with the misting option.

En référence à la figure 1, les bâtiments statiques sont constitués d'une ou plusieurs ouvertures au plafond (1), par lesquelles l'air chaud intérieur s'échappe suivant la différence de température entre l'intérieur (2) et l'extérieur (3), entraînant un vide d'air à l'intérieur, compensé par l'entrée d'air par les trappes latérales (4).Referring to Figure 1, static buildings consist of one or more ceiling openings (1), through which the warm indoor air escapes depending on the temperature difference between the interior (2) and the exterior (3), causing an air vacuum inside, compensated by the air intake by the side doors (4).

La colonne d'air ascendant (5) entre les trappes de coté (4) et l'ouverture au plafond (1), crée une induction (6) avec l'air intérieur, provoquant un mouvement d'air (7) au niveau des animaux.The ascending air column (5) between the side hatches (4) and the ceiling opening (1), creates an induction (6) with the interior air, causing an air movement (7) at the level animals.

En référence à la figure 2, la proximité de température entre l'intérieur (2) et l'extérieur (3) provoque une colonne d'air ascendant (5) avec une vitesse trop faible pour provoquer l'induction (6) de la figure 1. Le mouvement de l'air au niveau des animaux (7) est alors insuffisant ou nul, avec risque de maladie ou d'étouffement.With reference to FIG. 2, the proximity of temperature between the interior (2) and the exterior (3) causes an ascending column of air (5) with a speed too low to cause induction (6) of the Figure 1. The movement of air at the level of the animals (7) is then insufficient or zero, with the risk of illness or suffocation.

En référence à la figure 3, le bâtiment se trouve désormais équipé de l'invention (8) couplée à une commande par température (9) afin de se mettre en fonctionnement lorsque la température intérieure (2) devient trop élevée. Le dispositif en fonctionnement provoque un courant d'air (10) qui entraîne par induction (11) le mouvement d'air au niveau des animaux (7). La hauteur (12) entre le dispositif (8) et le sol (13) doit être judicieusement choisie, site par site, afin que le courant d'air (10) n'atteigne pas les animaux (7). Referring to Figure 3, the building is now equipped with the invention (8) coupled to a temperature control (9) to start operation when the interior temperature (2) becomes too high. The device in operation causes an air current (10) which induces (11) the movement of air at the level of the animals (7). The height (12) between the device (8) and the ground (13) must be carefully chosen, site by site, so that the air flow (10) does not reach the animals (7).

En référence à la figure 4, le dispositif est constitué d'un système de ventilation (13) de grand débit (plus de 20 000 m3/h), en dessous duquel vient se fixer, à l'aide de pattes de fixation (14), un diffuseur d'air (15) dont le centre (16) est relevé. Le dispositif est par ailleurs équipé de crochets de fixation (19) dans sa partie supérieure, afin de pouvoir être suspendu avec des câbles.Referring to Figure 4, the device consists of a ventilation system (13) of high flow (more than 20,000 m3 / h), below which is fixed, using fixing lugs (14 ), an air diffuser (15) whose center (16) is raised. The device is also equipped with fixing hooks (19) in its upper part, so that it can be suspended with cables.

En référence à la figure 5 le dispositif en service pousse l'air (17) du haut vers le bas pour le projeter vers les côtés (18) par le diffuseur (15).Referring to Figure 5 the device in use pushes the air (17) from top to bottom to project it to the sides (18) by the diffuser (15).

En référence à la figure 6, le dispositif décrit dans la figure 3 se trouve équipé de l'option de brumisation constituée d'un tuyau circulaire (20) faisant le tour du dispositif relié par un raccord (22) au tuyau d'arrivée d'eau. Sur le tuyau circulaire (20) sont montées des buses de brumisation (21) en nombre variable. La position des buses de brumisation (21) doit être choisie afin qu'elles se trouvent dans le flux d'air (18) de la figure 5. Referring to Figure 6, the device described in Figure 3 is equipped with the misting option consisting of a circular pipe (20) around the device connected by a connector (22) to the inlet pipe d 'water. On the circular pipe (20) are mounted misting nozzles (21) in variable number. The position of the misting nozzles (21) must be chosen so that they are in the air flow (18) of Figure 5.
