A method for operating a refrigeration system having a heat pump function for motor vehicle, including the following steps: setting a heat pump operation, in which the refrigerant is routed from the refrigerant compressor into the secondary line; setting an expansion valve assigned to the third heat exchanger such that a total mass flow of refrigerant flows through the third heat exchanger; and detecting the temperature of the coolant in the third heat exchanger. The total mass flow of refrigerant is routed through the third heat exchanger when the temperature of the coolant is greater than an upper limiting temperature.
