A dry suction refrigeration system includes an evaporator fed with liquid refrigerant which discharges a vapor refrigerant to an accumulator. A compressor receives vapor refrigerant from the accumulator and compressies the vapor refrigerant. A condenser receives the compressed vapor refrigerant from the compressor and transforms the refrigerant into liquid refrigerant. A receiver receives the liquid refrigerant from the condenser and supplies it to the evaporator. The evaporator includes an electronic expansion valve operable to continuously monitor the evaporation of liquid refrigerant in the evaporator and to continuously meter the flow of liquid refrigerant, so as to cause a complete vaporization of the liquid refrigerant. Because the liquid refrigerant is completely evaporated, the vapor refrigerant is moved through the system by pressure differential alone.
