Ghazali, supervisor Mechanical engineering Also available in printed version In recent years, there is an alarming concern over the negative impact of the release of chlorofluorocarbons (CFCs) into the environment from the refrigeration systems. Researchers have attempted to find solutions to overcome the problem. Thermoacoustic cooling/refrigeration is one solution that is being considered as it does not require any refrigerant with a rather simple mechanical system. Presently, the performance of a thermoacoustic refrigerator system is low. Experimental studies on the performance that have been conducted to date focused very much on the effects of the stack in the thermoacoustic resonator, hardly any on the inner resonator walls. Thermoacoustic cooling occurs on the walls as well as in the stack, though undesirable in the former. The resonators used in the experiments were a one diameter and a two-diameter tube with different internal surface area, in which a stack of optimized length is installed at an optimized location. Air at atmospheric pressure is the working gas. Temperature difference across the stack is measured to determine the performance of the thermoacoustic cooling attained. The completed experiments were done using single diameter and two-diameter resonator tubes that has different internal surface area. The results show that the smaller the surface area, the higher is the temperature difference. A temperature difference of 27.29°C is obtained for a single diameter with 16 mm diameter and the stack material is ABS. For 21 mm diameter tube with ABS and PLA as the stack material, the temperature difference is 21.69°C and 27.57°C respectively. For two diameter resonator, the highest temperature obtained is 7.86°C with the smallest internal surface area of 0.0123 m2. Thus, future thermoacoustic design should seriously take into account the resonator wall area in proportion where the thermoacoustic effect are desirable zulaihi UTM 82 p.
