A cooling or heating device in an absorption heat pump of GAX type, comprising a generator (1), a heat exchanger (2) of GAX type, an absorber (9B, 10B, 10C), a condenser (9A, 10A), an evaporator (10A-C, 9B), a pump (3) connected to said absorber and generator, a first circuit (15A-Z) for the refrigerant solution circulating through the device and connecting together at least said generator, GAX heat exchanger, absorber, condenser, evaporator and pump, and valve means (8) for modifying said first circuit (15A-Z) such as to vary the manner in which evaporator, absorber, condenser and evaporator are connected together; in which at least a first and a second heat exchange means (9, 10) are provided to enable at least one phase of the solution circulating through said means to be changed and to enable thermal energy to be exchanged against an external fluid, said first and second heat exchange means (9, 10) each comprising at least two mutually separate sub-heat exchanger (9A-B, 10A-C) arranged to function either as an evaporator or as an absorber and condenser, depending on the operating mode of the device. |
