Design and Experimental Study of Small-Scale Fabricated Thermo-Acoustic Refrigerator
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 9
Abstract
All refrigerator and air conditioning, contains refrigerants that are harmful to environment, CFC’s the original refrigerant, are depleting the ozone layer and replaced by HCFC’s or HFC’s the new product do not appear to harm ozone layer, but they do have the potential to lead to between 100 to 5000 times more global warming than CO2. The answer to current global warming effect due to conventional refrigeration is Thermo acoustic Refrigeration. Thermoacoustics is a field that combines thermodynamics, fluid dynamics and acoustics. In Thermo acoustics it is possible to construct thermo acoustic refrigerators, thermodynamic engines, prime movers and heat pumps which respectively use heat to create work, and use work to create or move heat. Thermo acoustic refrigerators have the advantage of operating with inert gases and with little or no moving parts, making them highly efficient ideal candidate for environmentally-safe refrigeration with almost zero maintenance cost. The goal of this investigation was to develop a standing-wave thermo acoustic refrigerator. The refrigerator should have a COP of at least 5. The performances of the thermo accoustic refrigerator with different aspects are discussed as well.
