ABSTRACT:
A vapor compression refrigeration system which has a multi-stage compressor, a condenser, a flash economizer, an economizer-condenser, a thermal economizer and a chiller. Liquid refrigerant is flashed in the flash economizer such that part of the liquid refrigerant changes state from a liquid to a gas absorbing heat from the remaining liquid refrigerant, the gaseous refrigerant being drawn into the compressor between stages or being condensed by the economizer-condenser within the flash economizer. An economizer damper valve is provided between the compressor and the flash economizer to regulate this flow of gaseous refrigerant to the compressor depending upon the thermal capability of the economizer-condenser to recondense the flashed refrigerant of the flash economizer.
