Abstract
A system may include a first compressor, a second compressor, a first heat exchanger and a second heat exchanger. The first compressor has a first inlet and a first outlet. The second compressor is a sumpless compressor and has a second inlet and a second outlet. The second compressor provides working fluid discharged from the second outlet to the first compressor. The first heat exchanger is disposed upstream of the second compressor and provides working fluid to the second compressor. The second heat exchanger is disposed upstream of the first compressor and provides working fluid to the first compressor.
