Heating device of a fluid that includes an absorption heat pump cycle

Claim 1

A liquid heating system utilizing an absorption solution heat cycle comprising: a burner having a substantially circular cylindrical combustion chamber; a first heat exchanger having a common wall with said combustion chamber for admitting and heating an absorption solution; a second heat exchanger heated by said burner and mounted in series with said first exchanger for admitting and heating a liquid; a separation column having a vertical cylindrical shape located directly above said combustion chamber for separating, at separate outlets, said absorption solution into distillates and residues, said combustion chamber including a plurality of baffles placed horizontally to constitute a simplified plate column, said separation column further communicating with said first exchanger; a panelling surrounding the combustion chamber for homogenizing the temperature of the solution to be regenerated in said separation column, said panelling being divided by a wall into a first and a second chamber, said first chamber admitting returns of said to be regenerated absorption solution before inserting the to be regenerated solution to said separation column, and said second chamber communicating directly with said absorption solution at the base of said column through at least one large opening for improving thermosiphon thermal exchanges; and a dephlegmator having an inlet connected to an outlet of said separation column for receiving the distillates for partial drying thereof, said dephlegmator further having an outlet connected to an inlet of said separation column for returning liquid parts of said distillates to said column.
