Efficiency = [Qr/Qd] x 100

where

Qr =[ Qv x Mr ]/td

Qr = heat required to vaporized moisture (kJ/h)

Qv = heat of vaporization of water , KJ/Kg

Qd = heat supplied to the dryer, KJ/h

Mr = moisture removed, kg

What is drying efficiency?

The coefficient of drying is a number about the utility of a dryer. A simple example : You have dirty clothes dry, and you wash them. So now, you have a totally of 4kg wet clothes and you put them on the dryer. The coefficient of drying K come from this formula : K = Weight of wet clothes / Weight of dry clothes So it depends from the speed of your dryer!

What is the reflux in washing drying?

In washing and drying processes, "reflux" refers to the phenomenon where a portion of the liquid solvent (usually water) is returned to the washing or drying chamber rather than being fully expelled. This can help maintain optimal temperature and humidity levels, improving the efficiency of the drying process. It also ensures that the washing solution remains concentrated, enhancing the removal of dirt and stains from fabrics. Reflux can contribute to better energy efficiency and reduced water consumption in washing and drying machines.
