A novel refrigerator for smart city

With development of smart cities and increasing awareness towards environmental degradation, use of conventional compressor based refrigerator is not very attractive. The fluid used to transfer the heat is flammable and also not suitable for environmental issues. Another way to transfer the heat is using current and this can be done using Peltier effect. In this paper we tried to understand advantages of Peltier based refrigerators with the help of designing a small prototype. The designed system is noise free, environment friendly system. Another advantage of this system is the size of the system can be small compared with conventional refrigerator, As Peltier devices will not work properly with very large temperature difference, it is good and viable solution for a small and portable refrigerator.
