Abstract

A quasi-steady state, coupled thermoelectric and heat transfer model heat and mass transfer lumped model was developed to predict the energy consumption and drying performance of domestic dishwashers. A numerical finite element solution was applied, assuming that the following components could each be treated as a lumped thermal capacitance: dish load, tub, wash water, and air in tub. The model was used to predict the energy consumption savings of heating water using a thermoelectric heat pump that extracts heat from the surrounding air, and the drying performance of circulating tub air through the cold and then hot side of TE modules.
