Abstract:
To help overcoming the biggest current challenge in
adopting evaporative cooling on a large scale, this study
presents a novel configuration for a hybrid equipment for
evaporative cooling with Tube Vortex (IEC/ VT cooler). The
main challenge for the evaporative cooling systems' good
performance is related to its high level dependency on the
ambient air conditions, which in damp or mild climates leads to
very limited cooling capacity. The main obstacle that makes it
difficult the proliferation of evaporative cooling systems is
represented by the minimum temperature value that can be
obtained during the process, whose value depends strongly on
the characteristics of the ambient air. In order to overcome this
difficulty it is presented a physical configuration of a new
system equipped with Vortex Tube for indirect evaporative
cooling to temperatures below the adiabatic saturation
temperature and, if necessary, below the dew point temperature.
Numerical values of the coefficient of performance of the new
evaporative cooler equipped with Vortex Tube are twice the
size of COPs for equipment with vapor compression cycle,
revealing a large potential for energy savings. By considering a
low value for the compression ratio, and thus enabling the use
of residual energy from pressurized gaseous effluents whose
cost is almost zero, this study states the effective technical and
economic feasibility of the evaporative cooler equipped with
Vortex Tube for industrial applications.
