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. The second heat exchange unit of the temperature level changer is connected to return rich solution to the discharge unit and it is also connected to receive the overheated vapor from the discharge unit.
A sorption heat pump comprising a discharge unit, an absorber, a condenser, an evaporator with a preconnected expansion valve, said condenser and said absorber being designed as a heat exchanger for heating a fluid utilized as an energy consumption fluid in an energy consumption device, said expansion valve being bridged by a bypass valve, with said condenser heat exchanger being separated from said energy consumption device by a valve capable of being actuated by a transmitter together with said bypass valve.
In a sorption heat pump including a fuel energized discharge unit for supplying fluid media for said heat pump and circuit means having said fluid media circulated therethrough and including heat exchanger means, absorber means, pump means, temperature level change means and energy consumption circuit means, said discharge unit operating to emit said fluid media into said circuit means as heated weak solution and to receive said fluid media returned from said circuit means as rich solution, and to also produce overheated vapor, the improvement wherein said temperature level change means comprise:
