Abstract
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.
