Claims

[Scope of utility model registration request]

A refrigeration cycle formed by sequentially connecting a compressor, a condenser, an expansion valve, and an evaporator through refrigerant pipes, and an oil that recovers oil from the refrigerant liquid extracted from the evaporator and makes it possible to return it to the compressor. A refrigeration system equipped with a recovery device, characterized in that the interior of the recovery device is separated into a plurality of oil concentrating chambers by partition plates that allow oil in the extracted refrigerant liquid to overflow. Device.
