Accumulator heat exchanger

An accumulator heat exchanger for use within a refrigeration system, the accumulator heat exchanger comprising:

• an accumulator vessel with an internal volume for accumulation of refrigerant fluid;
• a heat exchange coil disposed within the internal volume of the accumulator vessel, wherein the heat exchange coil encloses an axially extending inner volume of the heat exchange coil;
• a first inlet conduit for introducing the refrigerant fluid into the internal volume, the first inlet conduit extending from outside of the accumulator vessel to an inner end of the first inlet conduit within the internal volume of the accumulator vessel, and a first outlet conduit for exhausting superheated gaseous refrigerant from the internal volume, the first outlet conduit extending from within the internal volume of the accumulator vessel to outside of the accumulator vessel;
• and
• a second inlet conduit for subcooled refrigerant fluid and a second outlet conduit for the subcooled refrigerant fluid, wherein the second inlet conduit and the second outlet conduit provide an inlet and outlet flow path for the heat exchange coil, wherein
• the first inlet conduit comprises a plurality of outlets, each of the plurality of outlets adapted to direct the refrigerant fluid towards the axially extending inner volume of the heat exchange coil.
