Design and Fabrication of Thermoelectric Air Cooling and Heating System by Forced Convection Method

The increase in demand for refrigeration globally in the field of air-conditioning, food preservation, medical services, vaccine storages, and for electronic components temperature control led to the production of more electricity and consequently an increase in the CO2 concentration in the atmosphere which in turn leads to global warming and many climatic changes. Thermoelectric refrigeration is a new alternative because it can reduce the use of electricity to produce cooling effect and also meet today's energy challenges. Thermo electric refrigeration system uses peltier effect to produce hot and cold ends at each of its junctions. Cold end kept inside the cabinet to produce cooling effect inside the cabinet. Thermoelectric module can work either as a refrigeration system or a heat pump. This work presents an analysis of variation of temperature with respect to time for water cooled thermoelectric assembly. By dissipating large amount of heat from the hot side of module resulting in temperature drop in cold side of module.
