Description: The article examines the possibilities of modifying industrial air-conditioning systems through the use of vortex tubes (RanqueE"Hilsch tubes) based on the effect of temperature separation of compressed gas. Particular attention is paid to innovative technical solutions in the field of hydrodynamic and aerodynamic flow transformation, enabling cooling without the use of moving parts and traditional freon-based refrigerants. The advantages and limitations of vortex air-conditioning systems are analyzed, including their reliability, structural simplicity, operational safety, and energy-consumption characteristics. The publication provides a detailed overview of the engineering developments of industrial air-conditioning specialist Oleksandr Sylyaiev related to the application of integrated hydrodynamic interfaces and devices for mixing, homogenizing, and activating liquids and compressed gases. Special emphasis is placed on the description of structural elements that form coaxial annular flows and ensure homogenization of the turbulence level within mixed flows. The article also discusses the use of synthesized terminology, such as the Edouble Bernoulli effect,E followed by the JouleE"Thomson effect, in the context of new principles of flow transformation. The article emphasizes that the technical solutions proposed by Oleksandr Sylyaiev have significant potential for application in local and industrial air-conditioning systems, as well as in other fields requiring efficient mixing and activation of liquid and gaseous media with a minimal number of structural components and without the use of moving mechanical parts.
