An accumulator heat exchanger comprising an accumulator vessel with an internal volume for accumulation of refrigerant fluid. The accumulator vessel has a first inlet conduit for gaseous refrigerant and a first outlet conduit for superheated gaseous refrigerant; a heat exchange coil disposed within the accumulator vessel. The heat exchange coil has a second inlet conduit for subcooled refrigerant fluid and a second outlet conduit for subcooled refrigerant fluid. The second inlet conduit and second outlet conduit provide an inlet and outlet flow path for the heat exchange coil. A separator plate covers a cross-section of the inner volume of the heat exchange coil.

Accumulator heat exchanger

A refrigeration system includes a compressor configured to compress a refrigerant, a condenser, and an evaporator. A heat exchanger is disposed downstream of the condenser and upstream of the evaporator, and disposed downstream of the evaporator and upstream of the compressor, the heat exchanger configured to facilitate heat exchange between the refrigerant supplied from the condenser and the refrigerant supplied from the evaporator. A first expansion device is disposed downstream of the heat exchanger and upstream of the evaporator, and a second expansion device is disposed downstream of the condenser and upstream of the heat exchanger. The second expansion device is configured to cool the refrigerant passing therethrough to cool the refrigerant in the heat exchanger supplied from the evaporator to the compressor.
