A refrigeration system with integrated accumulator-expander-heat exchanger is disclosed. Refrigerant from a condenser/gas cooler is throttled through a capillary tube while at the same time undergoing a heat exchanging process with refrigerant from an evaporator. This method can elevate the compressor efficiency, increase the specific cooling capacity, and enhance the system performance. The capillary tube, which has dual functions of expansion device and heat exchanger, is placed inside a canister which also functions as an accumulator. The new device combining three separate parts into one can simplify the manufacturing process, lower the system size and weight, and thus decrease cost of the whole system.
