Abstract : This thesis documents the construction and performance measurement of a portable thermoacoustic refrigerator demonstration apparatus. The objective of the portable refrigerator is to graphically display, as a demonstration during lectures, a substantial thermoacoustic cooling power. Within minutes of start up, the apparatus develops frost on a small metal portion of the device. The refrigerator is small and compact and fits into a portable carrying case along with all ancillary equipment. The construction of the device had been started in a previous thesis project. This thesis describes the remaining construction steps required to complete the refrigerator and the subsequent performance evaluation of the unit in laboratory test trials. (MM)
