Abstract

L'invention porte sur une unité de ventilation à équilibre de pression atmosphérique comprenant : un premier ensemble bâti ayant un premier bâti destiné à délimiter une première ouverture de ventilation, un premier arbre tournant installé dans la première ouverture de ventilation et une première plaque d'ouverture/fermeture disposée sur le premier arbre tournant pour l'ouverture ou la fermeture de la première ouverture de ventilation par rotation conjointement avec le premier arbre tournant ; un second ensemble bâti disposé de façon adjacente au premier ensemble bâti ayant un second bâti destiné à délimiter une seconde ouverture de ventilation, un second arbre tournant installé dans la seconde ouverture de ventilation et une seconde plaque d'ouverture/fermeture disposée sur le second arbre tournant pour l'ouverture ou la fermeture de la seconde ouverture de ventilation par rotation conjointement avec le second arbre tournant, la seconde plaque d'ouverture/fermeture étant amenée à tourner par la différence entre les pressions atmosphériques respectivement appliquées aux deux côtés de la seconde plaque d'ouverture/fermeture afin d'ouvrir la seconde ouverture de ventilation ; une partie d'entraînement ayant un moteur statique relié au premier arbre tournant afin de faire tourner le premier arbre tournant en avant ou en arrière selon un signal d'ouverture ou de fermeture ; une partie de commande d'entraînement reliée à la fois au premier arbre tournant et au moteur statique pour la commande du moteur statique par coupure du signal d'ouverture ou de fermeture si le premier arbre tournant tourne à une vitesse angulaire prescrite ; et une partie de commande de verrouillage coopérant avec le premier arbre tournant et le second arbre tournant pour la limitation du second arbre tournant afin de maintenir la seconde ouverture de ventilation fermée lorsque le premier arbre tournant tourne à une vitesse angulaire prescrite pour ouvrir la première ouverture de ventilation selon le signal d'ouverture. Ainsi, l'unité de ventilation à équilibre de pression atmosphérique est installée entre deux ou plus de deux chambres de conservation à différentes températures ou entre une chambre de congélation et une chambre de refroidissement (ou entre une chambre chauffante produisant de la chaleur et une chambre chauffante recevant de la chaleur), afin que si une zone régulée doit être maintenue à une température supérieure ou inférieure, l'air d'une zone à plus basse température dotée d'une partie source de chaleur plus élevée ou d'une zone à plus haute température dotée d'une partie source de plus faible chaleur soit apporté à l'endroit adjacent à la zone régulée et la pression positive produite dans la zone recevant l'air soit renvoyée vers la région apportant l'air pour compenser la pression négative qui y est produite, ce qui maintient ainsi l'équilibre de pression atmosphérique afin de rendre la ventilation d'air sans à-coups, ce qui régule la température de l'endroit adjacent à la zone régulée. De plus, si une personne ou un produit agricole sont présents dans la chambre de conservation ou la première chambre et qu'un gaz nocif pour la personne ou le produit est produit en dépassant une concentration admissible dans la chambre et que le gaz détecté est provoqué par un feu, le gaz est évacué vers l'extérieur et de l'air frais provenant de l'extérieur est apporté à l'intérieur de la chambre ou si le gaz n'est pas provoqué par un feu mais est un gaz toxique particulier, le gaz présent dans la chambre est automatiquement évacué vers l'extérieur et de l'oxygène ou un gaz permettant de neutraliser le gaz toxique particulier sont introduits à l'intérieur de la chambre, ce qui abaisse ainsi la concentration du gaz toxique au-dessous d'une valeur prescrite.
