Abstract
A refrigerating apparatus including three compressors (A,B,C) and application side heat exchangers () () for two channels is formed so that a first compressor (A) is used only for the application side heat exchangers () in a first channel of a circuit, a third compressor (C) is used only for the application side heat exchanger () in a second channel of the circuit, and a second compressor (B) is used in a switchable manner between the application side heat exchangers () in the first channel of the circuit and the application side heat exchanger () in the second channel of the circuit. Thus, not only the pipe arrangement at suction side is simplified, but also operation control is streamlined.
