Abstract

Refrigeration is a process of reducing the temperature of an area or substance below the ambient temperature. In General refrigerator works by refrigerant circulating inside them to change liquid into gas, this process is called as evaporation. This system is based on the evaporator, compressor, condenser and expansion device .The refrigerant like Halons, Chlorofluorocarbon (CFC) and Hydro chlorofluorocarbon (HCFC) are used in the refrigeration system. Due to use of these refrigerants global warming and ozone depletion is potentially raised. Because of this ultraviolet radiation enters in earth’s atmosphere, the effect of this are skin cancer and eye damage. It also has effect on non-human animals and crops. To avoid this we need an alternative refrigeration system like thermoelectric cooler which is eco-friendly in nature. Many automobile engines have also emitted heat which is also a concern. Thermoelectric seat cooling system is the process of cooling the automobile seat during the summer season. The aim of this work is to cool the bike seat for the comfort of the riders. Due to the over heat in the seat, many medical problems like piles, kidney stone etc., that are affecting the riders. In order to reduce the stress to the riders and to overcome this effect, the concept of thermoelectric refrigeration system is used in automobile seat to control the seat temperature, we use exhaust fan and heat sink inside the seat to reduce the emission of the heat in the seat. This is light in weight, durable and high heat removal rate when compared to vapor compression refrigerator system and other type of refrigeration system.
