| Summary: | Thermoacoustic refrigeration is one of the best alternatives to conventional refrigeration systems due to the use of inert gases such as helium or air. On the contrary, conventional refrigeration systems use refrigerants (CFC) that are harmful to the environment and humans due to global warming and ozone layer depletion issues. It is possible to classify thermoacoustic technology as a clean, renewable technology with a bright future due to its many advantages. Thermoacoustic refrigerators' main function is to utilize sound waves to create a cooling effect. In the present study, the focus is on the design of a standing-wave thermoacoustic refrigerator driven by an ordinary loudspeaker using the simulation program DELTAEC. Additionally, investigating the influence of significant stack and resonator parameters (inertance and compliance) on cooling power and performance coefficient (COP). Hence, the designed thermoacoustic refrigerator performed well in respect of cooling power and coefficient of performance. It has achieved a cooling power of 312 W with a temperature difference of 25 K between the ambient and cold heat exchangers at a COP of 1.9275.
