Numerical modelling and a design of a thermoelectric dehumidifier

A prototype dehumidifier was designed and built based on thermoelectric cooling technology. A computational calculation model based on electric analogy was used in the deviceʹs design and optimisation (AERO), meaning that effects occurring inside the equipment, such as heat transfer, thermoelectric effects and the phase change which occurs during condensation and evaporation could be solved simultaneously. The thermoelectric dehumidifier prototype was built after performing several simulations using this calculation model. Numerous tests were carried out in order to optimise the Peltier pellet and fan supply voltages in experimental conditions. The prototype was also compared to conventional vapour-compression systems, thermoelectricity showing significant potential in the field.
