Abstract: The present invention relates to a refrigeration or air-conditioning apparatus which utilizes a vapor compression refrigeration system having a refrigerant circulating therethrough that comprises a compressor powered by an engine exhaust gas driven turbine. A mini centrifugal compressor may advantageously be used with such an apparatus, thus allowing the use of low GWP refrigerants. The present invention further relates to methods for powering a compressor, such as a mini-centrifugal compressor, in a refrigeration or air-conditioning apparatus, and methods for controlling compressor surge, impeller speed and cooling capacity.
