ABSTRACT The discovery that thermoacoustic phenomena can generate cooling for refrigeration has escalated research into thermoacoustic heat engine and refrigeration systems since the late twentieth century in developed countries. The simplicity of the thermoacoustic systems and its environmentally friendly operations has encouraged researchers in Malaysia to develop similar systems for specific purposes. A portable thermoacoustic refrigerator prototype using pure Helium as the working fluid was designed, fabricated and tested for thermoacoustic cooling effects. Based on the standing wave system with sinusoidal resonator geometry, a temperature drop was obtained repeatedly and consistently with cooling effects lower than the ambient when operating only at 1 atmospheric pressure. This paper reports the theory behind the design and fabrication procedure with initial temperature drop of 20K obtained from the first thermoacoustic refrigerator in Malaysia. Investigations into different geometry stack and the complete refrigerator system are underway to study the optimum performance that can be obtained.
