Abstract: A sorption heat pump including a fuel energized discharge unit from which heated fluid media for the heat pump is provided and a circuit having the fluid media circulated therethrough and arranged to include a heat exchanger, an absorber, pump devices, a temperature level changer and an energy consumption circuit. The discharge unit operates to emit the fluid media into the circuit as a heated weak solution and to receive the fluid media returned from the circuit as a rich solution. The discharge unit also produces an overheated vapor. The temperature level changer comprises a first and a second heat exchange unit, with the first unit being directly connected to the discharge unit to receive the weak solution therefrom, with the first unit also being connected to form part of a supply line for the energy consumption circuit.
