１項又は第２項記載の冷凍装置。[Claims for Utility Model Registration] (1) A refrigeration circuit consisting of a compressor, a condenser, a pressure reducer, and an evaporator connected through a refrigerant pipe is filled with non-azeotropic mixed refrigerants having different boiling points, and the A plurality of intermediate heat exchangers are provided in which a high-pressure refrigerant flow path from the pressure reducer to the compressor and a low-pressure refrigerant flow path from the pressure reducer to the compressor are combined in a state where they can exchange heat with each other, and the high-pressure refrigerant One or more gas-liquid separators are interposed in the flow path to reduce the pressure of the condensed refrigerant separated by the separators, and then send it to the low-pressure refrigerant flow path of the intermediate heat exchanger. In a refrigeration system configured to send a gas refrigerant to the high-pressure refrigerant flow path of the intermediate heat exchanger, the gas-liquid separator is provided with a refrigerant heater, and the high-pressure gas refrigerant separated by the gas-liquid separator is provided with a refrigerant heater. A temperature detector is attached to the outlet side flow path of the gas refrigerant, and the temperature of the cooling chamber equipped with the evaporator is controlled by operating the refrigerant heater based on the set temperature detection signal of the temperature detector. A refrigeration device characterized by being configured to maintain a constant temperature. (2) A refrigeration system according to claim 1, wherein a heater made of a heating wire is wound around the outer peripheral surface of an upright cylindrical gas-liquid separator. (3) Claims 1 or 2 of the utility model registration claim in which the set temperature of the temperature detector is set at a temperature between the highest boiling point in the mixed refrigerant and the next highest boiling point after the highest boiling point. refrigeration equipment.
