Abstract
A refrigerant recovery system includes a cylinder, a first detection unit, and a control unit. The cylinder accommodate a refrigerant filling a refrigeration cycle apparatus. The first detection unit detects a predetermined physical quantity in order to calculate a composition of the refrigerant accommodated in the cylinder. The control unit acquires a result of detection by the first detection unit and outputs the result as a first detection result.
