There are provided a high-yield economical, refrigerant processing apparatus for collected equipment which can recover and regenerate a liquid refrigerant by highly efficient thermal conversion and charge collected equipment with the liquid refrigerant, without releasing the refrigerant into the air, and an oil separator for use with the refrigerant processing apparatus. In the oil separator, an oil is separated from an oil-containing refrigerant to be recovered, and in a condenser, a gaseous refrigerant is converted into a liquid refrigerant. The oil separator has a heat exchanging double spiral pipe in which a double pipe made of a central pipe and an external pipe is formed spirally about a vertical central axis of the oil separator, and a heating unit for vaporizing the liquid refrigerant. The refrigerant processing apparatus for collected equipment has an oil recovery channel in which a remaining oil is recovered, a refrigerant regeneration and recovery channel in which the gaseous refrigerant is passed into the condenser and then through a central pipe from above the heat exchanging double spiral pipe, thereby regenerating the gaseous refrigerant as a liquid refrigerant and recovering the liquid refrigerant into a recovery bomb, and a refrigerant charging channel for charging the collected equipment with the liquid refrigerant regenerated from the gaseous refrigerant.
