Investigation of an atmospheric pressure thermoacoustic cooling system by varying its operating frequency

This paper deals with the construction and performance of a thermoacoustic cooling system. the design of each component of the apparatus is described along with the reasons of using specific materials. the thermoacoustic cooling system consists of acoustic driver (loudspeaker),resonator,stack and the electronic apparatus for measurements and data acquisition. the system was assembled and the study was on the performance of the thermoacoustic refrigeration system operating in an atmospheric pressure with respect to the change of operating frequency,the optimum frequency range was also defined and the maximum temperature difference is illustrated throughout this paper. © school of engineering,taylor's university.
