Beschreibung
Zusammenfassung:	An absorption refrigerating/heating apparatus comprising an evaporator (1) for accommodating a refrigerant, an absorver (2) for accommodating a solution which includes an absorbent for absorbing a vapor of the refrigerant produced in the evaporator (1), a regenerator (3) for extracting the refrigerant vapor by heating a portion of the solution to recover the concentration of the absorbent in the solution, and a condenser (9) for condensing the refrigerant vapor extracted and feeding the refrigerant thus condensed to the evaporator (1), in which the operation can be selected from a cooling mode, a thermodynamic heating mode, and a direct flame heating mode, said apparatus further comprising: a return passage (9a) for directly returning the refrigerant from the condenser (9) to the regenerator (3) in the direct flame heating mode; and means for feeding (P1,P2), in the direct flame heating mode, at least one of the refrigerant in the evaporator (1) and the absorbent solution in the absorber (2)to the generator (3) to have the concentration of the absorbent in the solution in the regenerator (3) lower than that in the thermodynamic heating mode.
