Abstract
A system may include first and second compressors and first, second and third heat exchangers. The first heat exchanger may receive working fluid discharged from the first and second compressors. The second heat exchanger may be disposed downstream of the first heat exchanger and may provide working fluid to the first compressor. The third heat exchanger may be disposed between the first and second heat exchangers and may include an inlet and first and second outlets. The first outlet may provide working fluid to the second heat exchanger. The second outlet may provide working fluid to the second compressor.
Claims27
A system comprising:
- a first compressor;
- a second compressor;
- a first heat exchanger receiving working fluid discharged from said first and second compressors;
- a second heat exchanger disposed downstream of said first heat exchanger and providing working fluid to said first compressor;
- a third heat exchanger disposed between said first and second heat exchangers and including an inlet and first and second outlets, said first outlet providing working fluid to said second heat exchanger, said second outlet providing working fluid to said second compressor;
- and
- a control module controlling operation of said second compressor between first and second modes based on a fluid pressure within said third heat exchanger, wherein said first mode is a full capacity mode and said second mode is a reduced capacity mode.
A system comprising:
- a first fluid passageway receiving working fluid from first and second compressors and including a first heat exchanger;
- a second heat exchanger including an inlet and first and second outlets, said inlet receiving working fluid from said first fluid passageway;
- a second fluid passageway extending from said first outlet to an inlet of said first compressor and including a third heat exchanger;
- a third fluid passageway extending from said second outlet to an inlet of said second compressor;
- and
- a control module controlling operation of said second compressor between first and second modes based on a fluid pressure within said second heat exchanger, wherein said first mode is a full capacity mode and said second mode is a reduced capacity mode.
A system comprising:
- a first fluid passageway receiving working fluid from first and second compressors and including a first heat exchanger;
- a second heat exchanger including an inlet and first and second outlets, said inlet receiving working fluid from said first fluid passageway;
- a second fluid passageway extending from said first outlet to an inlet of said first compressor and including a third heat exchanger;
- a third fluid passageway extending from said second outlet to an inlet of said second compressor;
- a fourth fluid passageway extending from said third fluid passageway to a location in said second fluid passageway between said third heat exchanger and said first compressor, said fourth fluid passageway including a valve selectively allowing and restricting fluid communication between said second and third fluid passageways;
- and
- a fifth fluid passageway fluidly isolated from said second and third fluid passageways and extending between said first fluid passageway and an intermediate-pressure inlet of said first compressor.
