Abstract:
(EN) A calculation device (57) calculates the degree of dryness of a refrigerant flowing from a second throttle device (52) on the basis of an inlet liquid enthalpy calculated on the basis of the temperature of the refrigerant flowing into the second throttle device (52), and on the basis of a saturation gas enthalpy and a saturation liquid enthalpy calculated by detecting of the temperature of the refrigerant flowing from the second throttle device (52) or the pressure of the refrigerant sucked into a compressor. Furthermore, the calculation device calculates the liquid-phase density and the gas-phase density of the refrigerant flowing from the second throttle device (52) on the basis of the temperature of the refrigerant flowing from the second throttle device (52) and the pressure of the refrigerant sucked into the compressor (1), and calculates the composition of the refrigerant circulating in a refrigeration cycle on the basis of the calculated degree of dryness, liquid-phase density, and gas-phase density.
(FR) Selon l'invention, un dispositif arithmétique (57) calcule le niveau de siccité d'un frigorigène déchargé par un second dispositif d'étranglement (52) sur la base de l'enthalpie d'un liquide d'entrée calculée d'après la température du frigorigène introduit dans le second dispositif d'étranglement (52), et sur la base des enthalpies d'un gaz saturé et d'un liquide saturé calculées d'après la détection de la température du frigorigène déchargé par le second dispositif d'étranglement (52), ou d'après la détection de la pression du frigorigène aspiré par une machine à compression. Le dispositif arithmétique (57) calcule également la concentration en phase liquide et en phase gazeuse du frigorigène déchargé par le second dispositif d'étranglement (52), sur la base de la température du frigorigène déchargé par le second dispositif d'étranglement (52), et sur la base de la pression du frigorigène aspiré par la machine de compression (1). Enfin, le dispositif arithmétique (57) calcule la composition du frigorigène circulant dans un cycle frigorifique, sur la base du niveau de siccité, et de la concentration en phase liquide et en phase gazeuse ainsi calculés.
(JA)  演算装置57は、第2の絞り装置52に流入する冷媒の温度に基づいて算出される入口液エンタルピーと、第2の絞り装置52から流出した冷媒の温度又は圧縮機に吸入される冷媒の圧力を検知するに基づいて算出される飽和ガスエンタルピー及び飽和液エンタルピーと、に基づいて第2の絞り装置52から流出する冷媒の乾き度を算出し、第2の絞り装置52から流出した冷媒の温度、及び圧縮機1に吸入される冷媒の圧力に基づいて、第2の絞り装置52から流出する冷媒の液相濃度及び気相濃度を算出し、算出された乾き度、液相濃度、及び気相濃度に基づいて冷凍サイクルを循環する冷媒の組成を算出する。
