Abstract
A system includes a flash tank, a load, a first compressor, a second compressor, and a liquid injection line. The flash tank stores a refrigerant. The load uses the refrigerant from the flash tank to remove heat from a space proximate the load. The first compressor compresses the refrigerant from the load. The second compressor compresses the refrigerant from the first compressor. The liquid injection line is coupled to the flash tank and to the second compressor and sends a liquid refrigerant from the flash tank to mix with the refrigerant from the first compressor before the refrigerant from the first compressor is received by the second compressor.
