Abstract
An integrated, self-contained microrefrigeration apparatus, in a dimension small enough to fit inside small appliances, such as electronic cases and portable equipment is described. The microrefrigerator employs a working fluid that circulates between evaporator, compressor, condenser and turbine-expander components in a closed loop. Two configurations are claimed: one with the compressor and turbine operating on independent shafts, and the other with the turbine and compressor both operating on the motor shaft.
