Liquid vapor separator

A method of separating liquid and vapor in a refrigerant system comprising:

• receiving a two-phase fluid at a chamber inlet of a cylindrical chamber,
• transporting the two-phase fluid upwardly through a first plurality of circular channels that are disposed adjacent to each other in the cylindrical chamber, whereby fluid coalesces on channel walls scooped through one or more gap channels, and drains through a first outlet gravitationally below the chamber inlet, wherein
• the cylindrical chamber further comprises:
• a second outlet for egress of gas contained in the two-phase fluid, wherein the chamber inlet is gravitationally above the first outlet and gravitationally below the second outlet;
• a cylindrical body disposed in the cylindrical chamber having the first plurality of circular channels that are disposed adjacent to each other, through which, during use, the two-phase fluid travels from the chamber inlet to the second outlet, and wherein the liquid within the two-phase fluid coalesces on walls of the first plurality of circular channels as the two-phase fluid passes through the first plurality of circular channels and the liquid is returned to the first outlet, and
• wherein:
• a top portion of the cylindrical body comprises the first plurality of circular channels, and a bottom portion of the cylindrical body comprises a single channel, wherein a diameter of the single channel is greater than the diameters for the first plurality of circular channels;
• and
• a bottom surface of the cylindrical body is gravitationally above the chamber inlet;
• the cylindrical body has an outer diameter that is smaller than a diameter of an inner wall of the cylindrical chamber, thereby defining an outer channel in the cylindrical chamber therebetween, wherein the outer channel extends a length of the cylindrical body from a top of the first plurality of circular channels to the chamber inlet, and wherein captured liquid flows gravitationally along the outer channel to the first outlet,
• wherein;
• the second outlet of the cylindrical chamber is cylindrical having a diameter that defines a diameter of the cylindrical chamber, and
• an end cap covers a top surface of the cylindrical body to define the second outlet, the end cap comprising a second plurality of circular channels configured to be respectively received within the first plurality of circular channels, wherein a plurality of gap channels is defined between the second plurality circular channels and the first plurality of circular channels for capturing coalescing liquid and guiding the coalescing liquid to the outer channel, so that the coalescing liquid flows gravitationally along the outer channel to the first outlet.
