ABSTRACT
In today’s world, many vehicles are equipped with heating, ventilating and air conditioning (HVAC) systems which are very efficient and reliable. But, the conventional compression systems have many drawbacks pertaining to energy efficiency and the use of refrigerants. Both these factors indirectly point to the impending scenario of global warming. To overcome these demerits, the existing HVAC system is replaced by newly emerging thermoelectric couple or cooler which works on peltier and seebeck effect. Thermoelectric cooling can be considered as one of the major applications of thermoelectric modules (TEM) or thermoelectric coolers (TEC).
The main objective of this project is to design a cooling system installed on a conventional blower of a car AC. The idea of cooling is based on Peltier effect, as when a dc current flows through TE modules, it generates a heat transfer and temperature difference across the ceramic substrates causing one side of the module to be cold and the other side to be hot. The purpose of the project is to make use of the cold side to cool the ambient air to a lower temperature, so that it can be used as a personal cooler
