Abstract
There is provided a method of operating a bimodal heat pump which in a first mode operates as an absorption heat pump and in a second mode operates as an evaporation-condensation device at a comparatively low ambient temperature. When switching from the first mode to the second mode, the evaporator and the absorber are uncoupled from the generator and the condenser. The generator and the condenser are operated in the second mode as an evaporation-condensation device, an extra quantity of working medium being present. The passage from the condenser to the evaporator is positioned at a level that provides the extra quantity of the working medium when starting the second mode.
