Claims

[Claims for Utility Model Registration] (1) A compressor, a condenser, a pressure reducing device, a freezer compartment cooler, and a refrigerator compartment cooler are connected in sequence to form a refrigeration cycle, and a non-azeotropic mixture is created during the cycle. In the refrigerator-freezer filled with refrigerant, a first bypass circuit is provided between the pressure reducing device and the freezer compartment cooler to switch the refrigerant flow to a first bypass circuit that bypasses the freezer compartment cooler and the freezer compartment cooler. A switching means is provided between the freezer compartment cooler and the refrigerator compartment cooler, and an outlet of the freezer compartment cooler, an inlet of the refrigerator compartment cooler, the first bypass circuit, and the first switching means are provided between the freezer compartment cooler and the refrigerator compartment cooler. A refrigerator-freezer characterized in that a second switching means is provided for switching a refrigerant flow between a second bypass circuit that bypasses a refrigerator compartment cooler. (2) The refrigerator-freezer according to claim 1, wherein the first switching means is a three-way valve. (3) The refrigerator-freezer according to claim 1 or 2 of the utility model registration, characterized in that the second switching means is a four-way valve. (4) The utility model registration request is characterized in that the second bypass circuit is provided with a check valve in the middle thereof that allows refrigerant to flow only from the four-way valve to the outlet side of the refrigerator compartment cooler. The refrigerator-freezer according to any one of items 1 to 3.
