Title
(EN) AIR CONDITIONING DEVICE
(FR) DISPOSITIF DE CLIMATISATION
(JA) 空気調和装置
Abstract
(EN) This air conditioning device is provided with: a refrigerant circuit wherein a compressor, a heat source-side heat exchanger, a first blocking device, an expansion unit, a use-side heat exchanger, and an accumulator are connected by means of a refrigerant pipe; a second blocking device, which is provided between the use-side heat exchanger and the accumulator, and which blocks a refrigerant flow from the accumulator side to the use-side heat exchanger side; a leakage detection unit that detects that the refrigerant has leaked; and a control device, which closes the first blocking device and controls the compressor to operate, in the cases where it is detected by the leakage detection unit that the refrigerant has leaked.
(FR) Ce dispositif de climatisation comprend: un circuit de fluide frigorigène dans lequel un compresseur, un échangeur de chaleur côté source de chaleur, un premier dispositif de blocage, une unité d'expansion, un échangeur de chaleur côté utilisation et un accumulateur sont reliés au moyen d'un tuyau de fluide frigorigène; un second dispositif de blocage, qui est disposé entre l'échangeur de chaleur côté utilisation et l'accumulateur, et qui bloque un écoulement de fluide frigorigène du côté accumulateur au côté échangeur de chaleur côté utilisation; une unité de détection de fuite qui détecte si le fluide frigorigène a fui; et un dispositif de commande, qui ferme le premier dispositif de blocage et commande le fonctionnement du compresseur, dans les cas où il est détecté par l'unité de détection de fuite que le fluide frigorigène a fui.
(JA) 空気調和装置は、圧縮機、熱源側熱交換器、第1の遮断装置、膨張部、利用側熱交換器及びアキュムレータが冷媒配管により接続される冷媒回路と、利用側熱交換器とアキュムレータとの間に設けられ、アキュムレータ側から利用側熱交換器側への冷媒の流れを遮断する第2の遮断装置と、冷媒が漏洩したことを検出する漏洩検出部と、漏洩検出部によって冷媒が漏洩したことが検出された場合、第1の遮断装置を閉じると共に、圧縮機を運転させるように制御する制御装置と、を備える。
