ABSTRACT:
A method of operating a monovalent alternative absorption heating plant an apparatus operated by this method in which above a predetermined ambient temperature, the system is operated in a heat pump mode and at lower temperatures, in a direct heating mode. The system uses a coolant (refrigerant) circulation path in which the coolant is driven out of a solvent enriched with the coolant, is liquefied, is vaporized by heat exchange with the environment and is absorbed by coolant-poor solvent. The system also has a heat carrier circulation in which the heat carrier is heated by heat exchange with the continuing coolant and thus takes up absorption heat. According to the invention, in the direct heating mode, the heat carrier bypasses the coolant condenser and absorber and is passed through a heat exchanger separate from the coolant condenser and is there heated directly by combustion heat in a heat generator or by heat exchange with the coolant-poor solvent.
