Abstract

Le conditionneur d'air multi- type connu ces dernières années établit un cycle de congélation en reliant une pluralité d'équipements extérieurs au fur et à mesure que la charge d'une opération de refroidissement/réchauffement augmente. Au cas où un équipement extérieur devant être activé et un équipement extérieur devant être arrêté coexistent, un réfrigérant liquide à haute pression, comme déchargé depuis l'équipement extérieur fonctionnant, s'écoule à travers un tuyau de liaison liquide dans l'équipement extérieur arrêté. Comme résultat, la quantité de réfrigérant en circulation dans le cycle de congélation peut être réduite et réduire la fiabilité d'un compresseur à cause d'une perte de capacité ou d'une décharge de température plus élevée à partir du compresseur. L'objet consiste à supprimer la réduction de la quantité de réfrigérant en circulation dans le conditionneur d'air multi-type. Dans le conditionneur d'air multi-type, une pluralité d'équipements extérieurs (10) et une pluralité d'équipements intérieurs (40) sont reliés en parallèle à un tuyau de liaison liquide (35) et à un tuyau de liaison de gaz (36), respectivement, pour établir le cycle de congélation. L'équipement extérieur (10) comprend un compresseur (11) relié à un tuyau de refroidissement de gaz à travers une soupape, un échangeur de chaleur extérieur (14) relié à ce compresseur, un récepteur (25) relié à cet échangeur de chaleur extérieur, et une soupape de commutation automatique (23) interposée entre ce récepteur et un tuyau de refroidissement de liquide. L'équipement extérieur est commandé de sorte que la soupape de commutation automatique (23) soit fermée quand l'opération est arrêtée. Même si l'équipement extérieur devant être activé et l'équipement extérieur devant être arrêté coexistent, alors, le réfrigérant n'est pas accumulé dans le récepteur de l'équipement extérieur devant être arrêté, de sorte que la réduction de la quantité du réfrigérant en circulation puisse être supprimée.
