The detail design of a turbomachine subsystem for a solar-powered water chiller is presented. The detail design activities include the overall turbomachine mechanical design, the gas bearing designs, aerodynamic design of a compressor and turbine stage, design of an electric motor and inverter, and a dynamic analysis of the rotor bearing system. A manufacturing cost analysis of the turbomachine subsystem is also provided. The turbomachine subsystem consists of a compressor-motor-turbine assembly which supports R-113 refrigerant cooling and power cycle loops. This rigid shaft assembly is suspended on gas film journal bearings and includes a Hydresil/sup TM/ gas film thrust bearing to support any axial thrust load. When the solar power supply is at design output, heat energy is transferred into the R-113 Freon gas power cycle and propels a radial inflow turbine. The turbine drives the R-113 Freon gas centrifugal compressor which activates the refrigeration cycle. When the solar supply is not adequate, the electric motor is used to augment the turbine.
