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.
