VORTEX TUBE REFRIGERATOR

The Vortex Tube is an interesting device in which a compressed gas (usually air) is divided into two streams at a lower pressure. One stream is approximately 50K colder and the other approximately 50K hotter than the compressed gas supplied – making it an unusual method for producing cooling air. In this unit, a modified industrial Vortex Tube has been incorporated into a test unit with all the controls and instruments necessary to provide students with an appreciation of its characteristics and performance.

Nozzles arranged tangentially around the circumference of the larger chamber discharge compressed gas at near sonic velocity into the chamber, creating a forced vortex rotating at approximately 500,000 rev/min.

The cold core of this vortex is extracted from the smaller end, while the hot periphery is extracted from the larger end. The ratio of cold to hot gas flow rates can be varied by a valve controlling the hot gas discharge. Learn about VORTEX TUBE REFRIGERATOR manufacturers for optimal educational outcomes.. To avoid frosting and flow meter errors, the hot and cold air streams are passed in opposite directions through a concentric tube heat exchanger, bringing both streams close to ambient temperature before passing through variable area flow meters to the atmosphere. A balance valve fitted at the hot end of the vortex tube controls the proportion of total air flow from each end.

The refrigerating effect is determined from the directly measured mass flow rate and temperature of the cold air stream.
