A method for operating a refrigeration system for a vehicle, which refrigeration system includes a refrigerant circuit having a heat pump function. The refrigerant circuit has an exterior heat exchanger, which is operated as a condenser or gas cooler in order to perform a refrigeration system mode or as a heat pump evaporator in order to carry out a heat pump mode. The refrigerant circuit has an interior heating condenser or heating gas cooler for carrying out a heating mode. The interior heating condenser or heating gas cooler is fluidically connected to the exterior heat exchanger, downstream, by a post-heating expansion device in order to carry out a post-heating mode. The opening cross-section of the post-heating expansion device is controlled in accordance with a refrigeration system parameter indicating the required post-heating power.
