  • Patent number: 11719475
    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.
    Type: Grant

  • Patent number: 11674720
    Abstract: A diffusion absorption refrigeration apparatus includes a bubble pump; a gas-liquid separator; a condenser; a gas branch pipe; an evaporator; an absorber; a gas heat exchanger; a storage tank; and a solution heat exchanger, in which a single material of trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)) and 2,3,3,3-tetrafluoropropene (R-1234yf), which have a low global warming potential (GWP), or a mixture thereof at a predetermined ratio is used as a refrigerant. Accordingly, the stability is high and a low GWP can be achieved.
