A turbocharged compressor system using an Organic Rankine Cycle system to recover waste heat from a compression process. The Organic Rankine Cycle system circulates an organic fluid through an evaporator, where the organic fluid vaporizes and is expanded in a turbine section of a turbocharger to drive a compressor section of the turbocharger. The organic fluid vapor is condensed in a condenser and is pumped to the evaporator once again for recirculation. The compressor section of the turbocharger pre-compresses a working fluid before entering an airend in a compression system. As the working fluid exits the airend, it may be delivered to the evaporator, where the waste heat from the working fluid evaporates the organic fluid flowing in the Organic Rankine Cycle system. The working fluid may also be circulated between intercoolers in multi-stage compressor systems.

COMPONENTS AND THE MANUFACTURE THEREOF VIA WELDING WITH REDUCED ALLOY-DEPLETION
Systems and methods form induction rotors by performing isostatic pressing (HIP) to weld clad to a shaft, which allows for scaling the manufacturing of solid steel rotors, as compared to conventional techniques. In examples, the rotors are designed for high-speed motors and may include recessed short circuit rings and/or end rings. An exemplary process molds an alloy powder into cladding such that heretofore unachievable rotor designs are achievable according to systems and methods described herein. In examples, a thin source-layer is introduced to welding zones, thereby enriching and strengthening the resulting joint at welding zones. The source-layer may be introduced by adding an intermediate layer comprising the source material between the materials being welded. The reduced alloy-depletion welding disclosed herein strengthens the welding area joints and provides for the manufacture of component designs, which were previously unachievable due to alloy-depletion weaknesses and environmental constraints.

The Organic Rankine Cycle system circulates an organic fluid through an evaporator, where the organic fluid vaporizes and is expanded in a turbine section of a turbocharger to drive a compressor section of the turbocharger. The organic fluid vapor is condensed in a condenser and is pumped to the evaporator once again for recirculation. The compressor section of the turbocharger pre-compresses a working fluid before entering an airend in a compression system. As the working fluid exits the airend, it may be delivered to the evaporator, where the waste heat from the working fluid evaporates the organic fluid flowing in the Organic Rankine Cycle system. The working fluid may also be circulated between intercoolers in multi-stage compressor systems.
