ONCLUSION
The results are clearly shown that the vortex cooling
capacity and the vortex tube efficiency has increased
when the hot tube surface temperature the thermoelectric
module is used to extract heat from the hot tube section of
the vortex tube. With the temperature difference across
the thermoelectric, the electrical power is generated as a
by-product. The cooling capacity and efficiency of the
vortex tube increase by 4.3 % and 9.6 % respectively.
