Abstract: A method and apparatus in connection with a vortex tube process. A pressurized medium flow is fed into a nozzle inlet. The medium flow expands while moving forward. The medium flow is twisted while entering a working tube. The twisted medium flow is divided into separate cold and hot flows. The cold flow is discharged from the vortex tube via a cold flow head after going through a hole in the center of a wall limiting a first end of the working tube. The hot flow is discharged from the vortex tube via a hot flow head after passing through the working tube having a flow valve at its second end. Parameters of thermodynamic processes in the vortex tube are controlled: by regulating the hot flow rate in the hot flow head by regulating the medium flow in the nozzle inlet, by regulating an efflux speed of the cold and/or hot flows in the vortex tube, and/or by intensification of heat transfer in the vortex tube by mechanical, chemical and/or electrical assemblies therein.
