Vapor compression system

A distributor for use in a vapor compression system comprising:

• an enclosure defining an enclosed volume, wherein the enclosure is configured to be positioned in a heat exchanger having a tube bundle comprising a plurality of tubes extending horizontally in the heat exchanger, wherein the enclosure comprises first and second longitudinal ends, two planar walls extending between the longitudinal ends, a curved end portion extending between the longitudinal ends and connected between first ends of the planar walls, and an end wall extending between the longitudinal ends and connected to second ends of the planar walls, opposite the first ends, wherein the curved end portion faces the tube bundle and the end wall faces away from the tube bundle;
• an inlet formed in the end wall and evenly spaced between the longitudinal ends of the enclosure, the inlet having a length between one sixth and one third of a length of the enclosure, and the inlet configured to receive a fluid into the enclosure;
• wherein a first longitudinal extent of the enclosure is defined by the length of the inlet, a second longitudinal extent of the enclosure is defined between the first longitudinal extent and one of the longitudinal ends, and a third longitudinal extent of the enclosure is defined between the first longitudinal extent and the other longitudinal end;
• wherein each of the longitudinal extents includes a plurality of slots formed through the curved end portion, and each of the slots is configured as an arc providing a spray angle of between 60 degrees and 180 degrees;
• and
• wherein the slots formed in the first longitudinal extent are evenly spaced from one another by a first distance, and the slots formed in the respective second and third longitudinal extents are evenly spaced from one another by a distance less than the first distance.
