Abstract
In an absorption heat pump capable of bivalent operation, to make possible combined operation in addition to the pure heat pump operation and the pure boiler operation, it is proposed to divide the refrigerant stream after the condenser and the stream of weak solution leaving the boiler, with one component stream of the refrigerant being fed through the refrigerant throttle and the vaporizer to a low-pressure absorber, into which a component stream of the weak solution is introduced through the temperature changer and the solvent throttle, while the other component stream of the refrigerant is fed either directly to the boiler or to a high-pressure absorber, to which the other component stream of the weak solution is fed directly in both cases, and to feed the strong solution from the low-pressure absorber through the temperature changer and/or the reflux condenser to the boiler, but on the other hand to feed the solution from the high-pressure absorber directly to the boiler.
