Abstract:
1. A refrigerant cycle comprising: at least two compressors, said compressors having discharge ports communicating with a common discharge manifold; and suction ports communicating with a common suction manifold; a first heat exchanger downstream of said discharge manifold; a main flow line leaving said first heat exchanger and leading to at least one economizer heat exchanger, and at least one tap line off of said main flow line upstream of said at least one economizer heat exchange, refrigerant in said tap line and refrigerant in said main flow line both passing through said at least one economizer heat exchanger, said main refrigerant flow returning to said compressors; and refrigerant in said tap line passing to at least one of said compressors downstream of said economizer heat exchanger and not passing to at least one compressor.
