Title (EN) AIR CONDITIONING SYSTEM AND REFRIGERANT BRANCHING UNIT
(FR) SYSTÈME DE CLIMATISATION ET UNITÉ D'EMBRANCHEMENT POUR RÉFRIGÉRANT
(JA) 空調システム又は冷媒分岐ユニット
Abstract:
(EN) The present invention reduces costs and suppresses workability deterioration in relation to improving security against refrigerant leakage. An air conditioning system (100) comprises: an outdoor unit (10); a plurality of indoor units (40); refrigerant communication pipes (La, Ga); and cutoff valves (84) that are disposed in the refrigerant communication pipes and that block the flow of refrigerant. Each refrigerant communication pipe includes: a plurality of second connection pipes (82) that communicate with the indoor units (40); a first connection pipe (81) that communicates with the plurality of second connection pipes (82); and a branching pipe (83) that connects the plurality of second connection pipes (82) and the first connection pipe (81). The first connection pipe (81) forms, through the second communication pipes (82), a common refrigerant flow passage for both refrigerant that flows from the outdoor unit (10) side to the indoor unit (40) side and refrigerant that flows from the indoor unit (40) side to the outdoor unit (10) side. The cutoff valve (84) is disposed in the first connection pipe (81).
(FR) La présente invention réduit les coûts et supprime la détérioration de la maniabilité vis-à-vis de l'amélioration de la sécurité contre les fuites de réfrigérant. Ce système de climatisation (100) comprend: une unité extérieure (10); une pluralité d'unités intérieures (40); des tuyaux de communication pour réfrigérant (La, Ga); et des vannes d’arrêt (84) qui sont disposées dans les tuyaux de communication pour réfrigérant et qui bloquent l'écoulement de réfrigérant. Chaque tuyau de communication pour réfrigérant comprend: une pluralité de seconds tuyaux de raccordement (82) qui communiquent avec les unités intérieures (40); un premier tuyau de raccordement (81) qui communique avec la pluralité de seconds tuyaux de raccordement (82); et un tuyau d'embranchement (83) qui relie la pluralité de seconds tuyaux de raccordement (82) et le premier tuyau de raccordement (81). Le premier tuyau de raccordement (81) forme par l'intermédiaire des seconds tuyaux de communication (82), un passage d'écoulement de réfrigérant commun à la fois pour le réfrigérant qui s'écoule du côté de l'unité extérieure (10) au côté de l'unité intérieure (40) et le réfrigérant qui s'écoule du côté de l'unité intérieure (40) au côté de l'unité extérieure (10). La vanne d’arrêt (84) est disposée dans le premier tuyau de raccordement (81).
(JA) 冷媒漏洩に対する保安性を向上させることに関連して、コスト及び施工性低下を抑制する。空調システム(100)は、室外ユニット(10)と、複数の室内ユニット(40)と、冷媒連絡配管(La、Ga)と、冷媒連絡配管上に配置され冷媒の流れを妨げる遮断弁(84)と、を備える。冷媒連絡配管は、室内ユニット(40)に連通する複数の第2接続管(82)と、複数の第2接続管(82)と連通する第1接続管(81)と、複数の第2接続管(82)及び第1接続管(81)を接続する分岐管(83)と、を含む。第1接続管(81)は、第2接続管(82)を経て、室外ユニット(10)側から室内ユニット(40)側へ流れる冷媒、及び室内ユニット(40)から室外ユニット(10)へ流れる冷媒、の双方に共通の冷媒流路を形成する。遮断弁(84)は、第1接続管(81)上に配置される。
