A refrigerant flow switching device for alternately conveying refrigerant from a high pressure and a low pressure evaporator to a compressor of a refrigeration system, and a refrigerator using such a refrigeration system, includes a refrigerant flow switching valve for alternately conveying refrigerant from the high and low pressure evaporators to the compressor. Said switching valve is controlled by a pressure switch that utilizes the pressure difference between the refrigerant from the high pressure evaporator and that from the low pressure evaporator to cyclically open or close a switch assembly, moving the switch between low and high pressure positions.
