Claims

[Claims for Utility Model Registration] 1. A suction-side oil separator that separates and removes refrigerating machine oil from refrigerant gas, a compressor that compresses the refrigerant gas that has passed through the suction-side oil separator, and refrigerant gas discharged from the compressor. A discharge side oil separator that separates and removes the refrigerating machine oil in the discharge side oil separator, a condenser that condenses and liquefies the refrigerant gas that has exited the discharge side oil separator, and a recovery tank that stores the refrigerant liquid that has been liquefied in the condenser. In a device for recovering refrigerant in a refrigeration cycle, a gas-liquid separator equipped with a refrigerant outflow valve that opens and closes depending on the position of the refrigerant liquid level and a purge valve that releases air to the outside is connected to the condenser and the above-mentioned gas-liquid separator. A refrigerant recovery device characterized in that it is disposed between a recovery tank. 2. Claim 1, characterized in that means is provided for cooling the refrigerant liquid and air inside the gas-liquid separator.
) refrigerant recovery device.
