Abstract

A method for operating a refrigeration system for a vehicle, the refrigeration system including a refrigerant circuit with a heat pump function. The refrigerant circuit has an exterior heat exchanger, which is operated as a condenser or gas cooler to perform a refrigeration system mode or which is operated as a heat pump evaporator to carry out a heat pump mode. The refrigerant circuit further 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 downstream of the exterior heat exchanger with a reheating expansion device therebetween to carry out a reheating mode. The opening cross-section of the reheating expansion device is controlled in accordance with a refrigeration system parameter indicating the required reheating power.
