Investigation of Thermoelectric Warm Air Heater

A novel thermoelectric warm air heater integrated thermoelectric with heat pipe exchanger. The operating voltage, indoor temperature and supply air temperature were simulated. The mathematical model of the warm air heater was founded to investigate the performance of the thermoelectric warm air heater. The simulation results showed that the optimum voltage of the device ranges from 6 V to 8 V. The hot and cold side thermal resistances of the heat pipe exchanger have a greater influence on heating performance than supply temperature. Recycling exhausted heat indirectly decreased the temperature difference of the hot side and cold side. The coefficient of performance can reach as high as 2.6 which is more energy-efficient than electric heating.
