(JA) 冷凍サイクル装置
Abstract:
(EN) In this refrigeration cycle device (100), a refrigerant circulates in the order of: a compressor (1); a condenser (2); a first expansion valve (4); and an evaporator (5). The refrigeration cycle device (100) is equipped with a first bypass flow path (11). The first bypass flow path (11) branches off from a first flow path connecting the compressor (1) and the condenser (2), and is connected, with a second valve (7) interposed therebetween, to a second flow path connecting the condenser (2) and the first expansion valve (4) or a third flow path connecting the evaporator (5) and the compressor (1). The opening degree of the second valve (7) in the cases when the evaporation temperature in the evaporator (5) is less than a first reference value is larger than that in the cases when the evaporation temperature is more than the first reference value.
(FR) La présente invention concerne un dispositif à cycle frigorifique (100) dans lequel un fluide frigorigène circule, dans l'ordre, à travers : un compresseur (1) ; un condenseur (2) ; un premier détendeur (4) ; et un évaporateur (5). Le dispositif à cycle frigorifique (100) comporte un premier circuit d'écoulement de dérivation (11). Le premier circuit d'écoulement de dérivation (11) se bifurque à partir d'un premier circuit d'écoulement reliant le compresseur (1) et le condenseur (2), et est relié, une seconde soupape (7) étant interposée entre eux, à un deuxième circuit d'écoulement reliant le condenseur (2) et le premier détendeur (4) ou à un troisième circuit d'écoulement reliant l'évaporateur (5) et le compresseur (1). Le degré d'ouverture de la seconde soupape (7) dans les cas où la température d'évaporation dans l'évaporateur (5) est inférieure à une première valeur de référence est plus grand que le degré d'ouverture dans les cas où la température d'évaporation est supérieure à la première valeur de référence.
(JA) 本発明に係る冷凍サイクル装置(100)においては、冷媒が、圧縮機(1)、凝縮器(2)、第1膨張弁(4)、および蒸発器(5)の順に循環する。冷凍サイクル装置(100)は、第1バイパス流路(11)を備える。第1バイパス流路(11)は、圧縮機(1)と凝縮器(2)とを接続する第1流路から分岐して、第2弁(7)を介して、凝縮器(2)と第1膨張弁(4)とを接続する第2流路、および蒸発器(5)と圧縮機(1)とを接続する第3流路のいずれかに接続される。第2弁(7)の開度は、蒸発器(5)における蒸発温度が第1基準値未満の場合の方が、蒸発温度が第1基準値より大きい場合より大きい。
