The paper presents the causes of research on the use of expanders in refrigeration systems. The possible types of expander are introduced. The turbine expander was selected for the comparative analysis. The results of theoretical and experimental work on cooling cycles with carbon dioxide as refrigerant in the supercritical and subcritical systems equipped with turbine decompressors were presented. It has been proven that the use of expanders has enabled energy savings in the level of 25%.
