Resumen:
Experimental and numerical models were used to analyze the kinetic
parameters that affect the clothes drying process in an electric vented
dryer. The numerical model was derived from a thermodynamic analysis of
a dryer using mass and energy balances. The experimental study used a
prototype of a dryer that was instrumented with data acquisition
equipment. A textile made from 50% polyester and 50% cotton was used
in the tests; the results were used to validate the model. The
temperature and relative humidity of the air at the drum inlet and
outlet, the evaporation rate, and the residual moisture in the clothes
were analyzed. A procedure to calculate the mass and heat transfer
coefficients inside the drum was presented. The numerical and
experimental results showed that the behaviors of coefficients obtained
at heating powers of 1300 W and 2000 W were almost constant during the
drying period.
