1. A method for operating a refrigeration appliance, the method comprising:
providing at least one warm storage compartment and at least one cold storage compartment;
providing a refrigeration device having a refrigerant circuit including at least two mutually parallel evaporators connected in series with a compressor, a condenser, and a shut-off valve disposed between the condenser and the evaporators, permitting each evaporator to cool a respective one of the compartments;
a) deciding whether a need for cooling has newly arisen in the warm storage compartment and, if so,
b) operating the compressor while the shut-off valve is closed to cause refrigerant to back up in the condenser,
c) opening the shut-off valve and supplying the evaporator of the warm storage compartment with the backed-up refrigerant, and
in step b) estimating a mass flow rate through the compressor and determining a time for carrying out step c) by using the estimated mass flow rate.
