A method of operating a refrigeration appliance, comprising the steps: operating a compressor and a valve system to cause refrigerant to flow through a refrigerant circuit to chill an evaporator during a compressor ON-cycle; operating the valve system to direct the refrigerant through a secondary pressure reducing device in response to the initiation of the compressor ON-cycle for a duration that lasts until a nominal operation condition has been reached; operating the valve system during the compressor ON-cycle to direct the refrigerant through a primary pressure reducing device in response to the nominal operation condition; and transferring thermal energy from the primary pressure reducing device to a suction line heat exchanger.
