Vapor compression system
A distributor for use in a vapor compression system includes an enclosure configured to be positioned in a heat exchanger having a tube bundle including a plurality of tubes extending substantially horizontally in the heat exchanger. At least one distribution device formed in an end of the enclosure positioned to face the tube bundle, the at least one distribution device configured to apply a fluid entering the distributor onto the tube bundle. The enclosure has an aspect ratio between about ½:1 and about 10:1.
1. 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.
2. The distributor of claim 1 , wherein the enclosure has an aspect ratio of height to width between 2:1 and 6:1.
3. The distributor of claim 1 , wherein the planar walls are disposed between zero degrees and 45 degrees from parallel to each other.
4. The distributor of claim 1 , wherein the planar walls are disposed parallel to each other.
5. The distributor of claim 1 , wherein the enclosure has an aspect ratio of height to width between 2:1 and 4:1.
6. The distributor of claim 1 , wherein the enclosure has a 2:1 aspect ratio of height to width.
7. The distributor of claim 1 , wherein the enclosure has a 4:1 aspect ratio of height to width.
8. The distributor of claim 1 , wherein the spray angle is between 160 degrees and 170 degrees.
9. The distributor of claim 1 , wherein the spray angle is 165 degrees.
10. The distributor of claim 1 , wherein each of the slots is evenly sized.
11. A method for using the distributor according to claim 1 , the method comprising:
operating the vapor compression system; and
spraying the fluid onto an exterior of the tubes.
