Abstract

The invention relates to a method of operating a heat pump system in an absorption heat pump mode and/or boiler heating mode. According to this method, a solution of a refrigerant in a solvent is heated in a boiler, the evaporated refrigerant is delivered either directly to an absorber through a condenser, a throttle and an evaporator when the system is operated in the heat pump mode, or directly to an absorber when the system is in the boiler heating mode. The refrigerant is combined with the solvent that is drawn, low in refrigerant, from the boiler. The rich solution thus obtained is redirected to the boiler. To shut down the system, the heating of the boiler is turned off. In order to accelerate the return to operation, the invention provides that the flow line connecting the boiler with the absorber is additionally closed when the shutdown is effected and the refrigerant line from the boiler to the absorber is opened for a short time when the pressure in the boiler exceeds a predetermined maximum value, until the pressure in the boiler drops back below the maximum value.
