What is vortex tube refrigeration?
3.8 Vortex tube refrigeration systems
A vortex tube is a mechanical-thermal device that separates a compressed flow of air (or any inert gas) into hot and cold streams and has no mechanical moving parts [149–152].
What are the advantages of vortex tube over other refrigeration system?
Advantages of Vortex Tube Refrigeration Systems
It requires less space and is light in weight. Capital and production costs are less. In this system, compressed air is readily available. Simple in maintenance and expert attendant is not required.
How do vortex tubes work?
The gas exiting the hot end of the tube is at twenty-eight point five degrees Celsius while the gas at the cold end of the tube is down to two point one degrees Celsius.
What are the components used in vortex tube refrigeration system?
The different components of a vortex tube refrigeration system are orifice, nozzle, control valve, vortex chamber, hot end side and cold end side. Vortex chamber is where high pressure fluid flow with high velocity and the energy transfer occurs between the outer flowing fluid and the inner fluid [11].
Where are vortex tubes used?
A control valve in the hot air exhaust adjusts temperatures, flows and refrigeration over a wide range. Vortex tubes are used for cooling of cutting tools (lathes and mills, both manually-operated and CNC machines) during machining.
How efficient is vortex tube?
Accordingly, the analysis of experimental data shows the maximum isentropic efficiency of the vortex tube enclosure cooling is 0.37 at the cold mass fraction of 0.45. Air temperature in the enclosure is about 13°C in average.
Will a vortex tube work with water?
This question comes up occasionally and surprisingly the answer is yes, but not like how you may think. One explanation put forward is that this happens because normally a liquid used has a vapor pressure.
