Abstract: A refrigerant regenerating apparatus is disclosed. A refrigerant regenerating apparatus of the present disclosure includes: a regenerator into which a refrigerant flows and from which the refrigerant is discharged, the regenerator configured to separate and discharge oil contained in a refrigerant flowing in the regenerator; and a recoverer into which the refrigerant discharged from the regenerator flows, the recoverer including a compressor configured to compress a refrigerant flowing in the recoverer and a heat exchanger configured to condense a refrigerant discharged from the compressor, in which the regenerator includes: a charger configured to charge oil contained in the refrigerant flowing in the regenerator with positive ions or negative ions using corona discharge; and a collector configured to electrically collect the oil charged through the charger.
