Abstract
The present disclosure relates to a compressor having a first rotor and a second rotor disposed within a housing, where the first rotor is configured to rotate about a first axis of the housing and the second rotor is configured to rotate about a second axis of the housing. The first rotor and the second rotor engage with one another such that rotation of the first rotor and the second rotor pressurizes a vapor within the housing. The compressor includes an end plate coupled to a discharge end of the housing, where the end plate includes a variable opening configured to discharge a flow of the vapor from the housing. The end plate also includes a first movable member and a second movable member that are configured to increase or decrease a cross-sectional area of the variable opening to adjust the flow of the vapor.
Claims16
A compressor for a vapor compression system, comprising:
- a housing;
- a first rotor and a second rotor disposed within the housing, wherein the first rotor is configured to rotate about a first axis of the housing and the second rotor is configured to rotate about a second axis of the housing, wherein the first rotor and the second rotor are configured to engage with one another such that rotation of the first rotor and the second rotor pressurizes a vapor within the housing;
- and
- an end plate coupled to a discharge end of the housing, wherein the end plate comprises:
- an inner surface;
- an opening extending through the inner surface and configured to receive a shaft of the first rotor;
- a variable opening extending through the inner surface and configured to discharge a flow of the vapor from the housing;
- a first groove recessed in the inner surface;
- a second groove recessed in the inner surface;
- and
- a first movable member disposed within the first groove and a second movable member disposed within the second groove, wherein the first movable member is configured to slide along the first groove and the second movable member is configured to slide along the second groove to increase or decrease a cross-sectional area of the variable opening to adjust the flow of the vapor, the first groove and the second groove each define a respective first stop and a respective second stop, the first stop of the first groove and the second stop of the first groove are configured to limit movement of the first movable member within the first groove via contact with the first movable member, and the first stop of the second groove and the second stop of the second groove are configured to limit movement of the second movable member within the second groove via contact with the second movable member.
A vapor compression system, comprising:
- a compressor including a first rotor configured to rotate about a first axis and a second rotor configured to rotate about a second axis, wherein the first rotor and the second rotor are configured to engage with one another to compress a refrigerant within a housing of the compressor;
- and
- an end plate coupled to the housing, wherein the end plate comprises:
- an inner surface;
- a first opening extending through the inner surface and configured to receive a first shaft of the first rotor;
- a second opening extending through the inner surface and configured to receive a second shaft of the second rotor, wherein the inner surface circumferentially surrounds the first opening and the second opening independently of one another;
- a variable opening extending through the inner surface and configured to discharge a flow of the refrigerant from the housing to circulate the refrigerant through the vapor compression system;
- a first groove recessed in the inner surface;
- a second groove recessed in the inner surface;
- and
- a first movable member disposed within the first groove and a second movable member disposed within the second groove, wherein the first movable member is configured to slide along the first groove, the first movable member extends only partially about a first circumference of the first opening, the second movable member is configured to slide along the second groove to adjust a cross-sectional area of the variable opening, and the second movable member extends only partially about a second circumference of the second opening.
