This invention relates to a refrigeration system designed as Rotary Supercharger Ejector Refrigeration System to improve the coefficient of performance and to reduce mechanical complexity. The design ensures that the working fluid performs expansion work as it passes through the generator. On the other hand, it eliminates the need for subcooling the liquid entering the pump. The design allows conversion of the high-speed kinetic energy from the ejector's outlet stream into recoverable potential energy. Consequently, the cycle closely approaches the ideal cycle. The rotation of coils increases convective heat transfer between coils and the atmosphere and eliminates the need for a blower as well as a complex mechanical pump. In addition to coil-air heat exchange, the system can be thermally coupled with hot rotating bodies to absorb waste heat and generate effective cooling.
