Abstract:
A chlorofluorocarbon recovery device for extracting and recovering chlorofluorocarbon from car air conditioners, home air conditioners, and refrigerators that are to be scrapped, wherein a compressor (4) for a car air conditioner that is driven by an engine is used to obtain suction force for recovering chlorofluorocarbon, wherein a condenser (5) to liquefy chlorofluorocarbon gas used in a car air conditioner is used in addition to said compressor, wherein said engine is used as a driving source both for running a vehicle and recovering chlorofluorocarbon, wherein a suction hose (10) is connected to the suction port of said compressor, wherein said hose is then connected to a chlorofluorocarbon injection valve of an air conditioner to be scrapped so as to suck in chlorofluorocarbon gas, wherein chlorofluorocarbon gas so sucked in by means of said compressor is liquefied by means of said condenser so as to be recovered in a recovery container (17), and wherein oil separators (8) and (13) are provided on the suction and discharge sides of said compressor, respectively, whereby oil contained in chlorofluorocarbon gas is separated, thereby allowing only chlorofluorocarbon gas to be recovered in said recovery container.
