GENERATOR FOR A REFRIGERATOR/ABSORPTION HEAT PUMP, AND A REFRIGERATOR/ABSORPTION HEAT PUMP PRESENTING SAID GENERATOR

摘要

The refrigerator/absorption heat pump (1) comprises a generator (2) connected to a condenser (3), to a pressure reducer device (4), to an evaporator (5) and to an absorber (6) which is itself connected to the generator (2) via a positive displacement pump (6b). The generator (2) comprises, for containing a refrigerant mixture, a shell (11) presenting a plurality of heat transfer fins (13), and a casing (14) surrounding the shell (11) and defining with the shell (11) an interspace (15) through which a thermovector fluid can circulate to heat the refrigerant mixture. Guide means (18) for the heating fluid are housed inside the interspace (15) to facilitate heat transfer to the refrigerant mixture.
