Abstract
A vapor compression system () has: first (A;A;A) and second (B;B;B) compressors; first () and second () heat exchangers; and one or more expansion devices (A,B). Means (A,B;A,B,A,B;A,B,A,B) are provided for switching the system between operation in first and second modes using the respective first and second compressors. In the first mode: the first compressor compresses refrigerant; the compressed refrigerant is cooled in the first heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the second heat exchanger. In the second mode: the second compressor compresses refrigerant; the compressed refrigerant is cooled in the second heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the first heat exchanger.
