ABSTRACT:
A method of heating with an absorption heat pump in which absorber pressure is produced independently of evaporation pressure by a compressor, and/or the lean mixture returning to the absorber is cooled in a main heat exchanger to temperatures lower than is possible in the heat exchanger located between the absorber and the desorber, and the desorber is operated adiabatically. A jet apparatus may be used as a compressor unit. The cooling agent cycle may be shut off in case of inadequate evaporator pressure dependent on the outside temperature, and the mixture cycle may be used as a heat carrier. The heat exchanger may be bypassed during heat carrier operation and the heat may be delivered exclusively via the main heat exchanger. If the desorber operates on oil, gas or solid fuel, fuel gases may be cooled in a unit behind the desorber by a medium to be heated. The flue gas is used for evaporating liquid cooling agent and the vaporous cooling agent is used for driving the compressor. A gear pump may be used as mixture pump. A pipe with cooling agent injection and/or static mixers may be used as adiabatic absorber.
