Piezo-electrically driven Thermoacoustic Refrigerator

P. Ramesh, V. Hari Prakash, P. Bharath, M. Hari Prasad


Thermoacoustic refrigeration is an emerging field of technology. This technology uses sound waves to pump heat across a temperature gradient and the sound waves are produced using piezoelectric material. The main aim of this idea is to reduce the usage of harmful refrigerants which are great threat to the global warming. The study focuses technically on using the piezo-electric materials to get the desired refrigeration effect. Moreover, the added advantage is that piezo-electrical material replaces the electromagnetic speakers which causes disturbances and expensive too. Finally, the positive outcome of this project is that the efficiency rate is higher when compared to other refrigeration systems.
