Abstract
An accumulator and oil separator device includes a housing having a cavity, an oil separator unit disposed in the cavity and designed to separate oil from a refrigerant and oil mix received from a compressor and to output the oil into the cavity. The accumulator and oil separator device further includes an accumulator inlet tube to carry a received refrigerant into the cavity. The accumulator and oil separator device also includes an accumulator outlet tube to output the received refrigerant and the oil from the cavity.
Claims19
An accumulator and oil separator device, comprising:
- a housing having a housing cavity;
- an oil separator unit comprising a shell having a shell cavity, and a float disposed within the shell cavity and configured to control an output of oil into the housing cavity based on a surface level of separated oil, wherein the oil separator unit is disposed in the housing cavity and wherein the oil separator unit is designed to separate oil from a refrigerant and oil mix received from a compressor;
- an oil separator inlet tube extending from outside the housing to a top cover of the shell, wherein the oil separator unit receives the refrigerant and oil mix from outside of the housing via the oil separator inlet tube;
- an oil return tube extending from a top cover of the shell and configured to output the oil onto the top cover of the shell and into the housing cavity;
- an accumulator inlet tube to carry a received refrigerant into the housing cavity;
- and
- an accumulator outlet tube to output the received refrigerant and the oil from the housing cavity.
