Refrigeration system utilizing an expansion jet compressor

摘要

A closed loop vapor cycle refrigeration system an expander-compressor is disclosed. A portion of the liquid refrigerant in the system is expanded into gas. This gas is used to operate a compressor. The compressor compresses the low pressure gas from the evaporator and discharges the compressed gas either to a primary compressor or the condenser. A novel expander-compressor device is also disclosed for use in the refrigeration system.
