The Reduction of Temperature in a Chamber with Heat Load using Cold Air from a Vortex Tube
Abstract
This research aims to study the reduction of temperature in a chamber by a cold air from a vortex tube. An electrical appliance as a heat load is inside the chamber. The testing chamber dimension is 30 cm width, 41 cm height and 30 cm depth. The analysis on the cooling capacity of vortex tube show its cooling capacity of 70 W and the cooling temperature difference of 27oC at the inlet compressed air of 3 bar. The electrical appliance generated heat when operate in the test chamber cause the temperature increase rate of 1.1°C/min. The use of cold air produced by a vortex tube could reduce the chamber temperature by 0.6oC/min. This imply that the vortex tube can deduct heat in the chamber.
