Abstract (en)
[origin: EP3462108A1] A refrigeration device is equipped with: an extraction pipe (19) that extracts a portion of a non-azeotropic refrigerant mixture from between a condenser (5) and an expansion valve (7); an extraction pipe on-off valve (20); a gas-liquid separator (17) that is connected to the extraction pipe (19), and that accumulates the non-azeotropic refrigerant mixture and separates the mixture into a gas and a liquid; a gas return pipe (21) connecting the gas-phase portion inside the gas-liquid separator (17) and a point between the expansion valve (7) and an evaporator (9); a gas return pipe on-off valve (22); a liquid return pipe (23) connecting the liquid-phase portion inside the gas-liquid separator (17) and a point between the expansion valve (7) and the evaporator (9); a liquid return pipe on-off valve (24); and a control unit that controls the extraction pipe on-off valve (20), the gas return pipe on-off valve (22), and the liquid return pipe on-off valve (24).
