Using the Direct and Reverse Rankine Cycles to Create a Water-Cooling Chiller Running on Waste Heat

Abstract

This article presents the scheme for a Freon heat-recovery refrigeration unit developed on the basis of the forward and reverse Rankine cycle for cooling water. The arguments in favor of the possibility to create such small installations for cooling (5 kW at the temperature level of 5°C) are presented on the basis of turbomachinery (centripetal radial-axial turbines and centrifugal compressors). The calculated thermal coefficient for the installation is compared with the thermal coefficient of a single-stage absorption chiller running on an aqueous solution of lithium bromide.
