What is disclosed is a heat exchanger-accumulator for vaporizing a refrigerant or the like, characterized by an upright pressure vessel having a top, bottom and side walls; an inlet conduit eccentrically and sealingly penetrating through the top; a tubular overflow chamber disposed within the vessel and sealingly connected with the bottom so as to define an annular outer volumetric chamber for receiving refrigerant; a heat transfer coil disposed in the outer volumetric chamber for vaporizing the liquid refrigerant that accumulates there; the heat transfer coil defining a passageway for circulating an externally supplied heat exchange fluid; transferring heat efficiently from the fluid; and freely allowing vaporized refrigerant to escape upwardly from the liquid refrigerant; and a refrigerant discharge conduit penetrating sealingly through the top and traversing substantially the length of the pressurized vessel downwardly and upwardly such that its inlet is near the top of the pressurized vessel so as to provide a means for transporting refrigerant vapor from the vessel. The refrigerant discharge conduit has metering orifices, or passageways, penetrating laterally through its walls near the bottom, communicating respectively interiorly and exteriorly of the overflow chamber for controllably carrying small amounts of liquid refrigerant and oil to the effluent stream of refrigerant gas.

A heat exchanger-accumulator for vaporizing a refrigerant or the like, comprising: a. an upright, pressure vessel having top, bottom, and side walls; b. an inlet conduit eccentrically and sealingly penetrating through said top so as to discharge said refrigerant downwardly along said side wall of said pressurized vessel when refrigerant flows through said inlet conduit; c. a tubular overflow chamber disposed within said vessel and sealingly connected with said bottom so as to define also an annular outer volumetric chamber for receiving said refrigerant such that liquid refrigerant will settle toward the bottom, being isolated from the liquid in said outer volumetric chamber until said liquid overflows the top of said overflow chamber; d. a heat transfer coil disposed in said annular outer volumetric chamber for vaporizing liquid said refrigerant; said heat transfer coil comprising a coil defining a passageway for heat exchange fluid and having means for transferring heat efficiently from said fluid to said refrigerant and freely allowing vaporized refrigerant to escape upwardly from the liquid said refrigerant; said coil having inlet and outlet conduit means for conducting said fluid and penetrating laterally through said walls of said pressure vessel; said heat transfer coil traversing longitudinally of said pressurized vessel from adjacent the top of said overflow chamber to adjacent said bottom; e. refrigerant discharge conduit means for carrying effluent refrigerant; said refrigerant discharge conduit means penetrating sealingly through said top, extending downwardly adjacent said bottom and back upwardly to have its inlet disposed adjacent said top have said overflow chamber; said refrigerant discharge conduit having metering passageways penetrating laterally through said conduit means near said bottom for allowing a controlled flow of liquid into said discharge conduit, at least one said metering passageway communicating interiorly of said overflow chamber adjacent its bottom and at least one said metering passageway communicating with said annular outer volumetric chamber adjacent its bottom; said metering passageways serving to controllable carry small amounts of a liquid refrigerant and oil that may accumulate into the effluent stream of refrigerant gas.
