1. A refrigeration system comprising:
an evaporator comprising an intake port and a discharge port, the evaporator being configured to evaporate a cold refrigerant from a liquid-vapor state to a vapor state; a compressor comprising an intake port and a discharge portion, the intake port of the compressor being in fluid communication with the discharge port of the evaporator, the compressor being configured to receive refrigerant discharged from the evaporator and compress the refrigerant to an elevated, sub-critical pressure; a condenser comprising an intake port and a discharge port, the intake port of the condenser being in fluid communication with the discharge port of the compressor, the condenser being configured to receive refrigerant discharged from the compressor and condense the refrigerant discharged from the compressor to one of a saturated-liquid state, a liquid state cooler than the saturated-liquid state, and a liquid-vapor state near the saturated-liquid state; an energy recovery apparatus comprising an intake port and a discharge port, the intake port of the energy recovery apparatus being in fluid communication with the discharge port of the condenser, the discharge port of the energy recovery apparatus being in fluid communication with the intake port of the evaporator, the energy recovery apparatus further comprising a nozzle, a turbine, and a generator, the nozzle being configured to expand refrigerant discharged from the condenser and increase velocity of the refrigerant as it passes through the nozzle, the turbine being positioned and configured to be driven by refrigerant discharged from the nozzle, the discharge port of the energy recovery apparatus being downstream of the turbine, the generator being coupled to the turbine and driven by the turbine, the generator being configured to produce electricity as a result of the turbine being driven by refrigerant discharged from the nozzle. |
