The Kleemenko cycle or one-flow cascade cycle is a single-stream mixed-refrigerant technique used to cool or liquefy gases. The term Kleemenko Cycle is used in refrigeration if multi-component refrigerants (MCR) are used in a cycle.^[1]

The Russian scientist Aleksandr Petrovich Klimenko (Александр Петрович Клименко) described the one-flow cascade cycle in the Proceedings of XIII International Conference of Refrigeration in Copenhagen, Denmark, in 1959. It was published in "progress in refrigeration science and technology", Volume I Pergamon Press in 1960 pps. 34–39.^[2]
