摘要：A method of switching refrigerant flow between a path to a freezer evaporatorin a freezer compartment and a path to a fresh food evaporator in a fresh foodcompartment of a refrigerator includes providing a three-way valve with at least three
operational positions in flow communication with the path to the fresh food evaporatorand the path to the freezer evaporator. A temperature difference (dt) between a freezercompartment temperature and a freezer evaporator evaporating temperature ismeasured. A temperature difference (dt) between a fresh food compartmenttemperature and a fresh food evaporator evaporating temperature is measured. Theoperation of the three way valve is controlled based on at least one of dtand dt.
