Abstract/Summary
In the Thermoacoustic Refrigerator Cal Poly Mechanical Engineering senior project, we designed, built, and tested a thermoacoustic refrigeration system which achieved an average temperature difference of 11.0°C. Our system consists of a resonator tube with an instrumented stack, mounted onto a base with a speaker and amplifier. An external power supply and function generator provide the power and signal to the system, and a thermocouple reader displays the temperature of the top and bottom of the stack. The system consistently achieved a significant temperature difference between the two ends of the stack in various ambient conditions, and it was quick to respond, reaching a 5-6°C difference within 2-3 minutes. Our project documents the steps to make a simple thermoacoustic system and provides a promising learning tool for the Cal Poly Mechanical Engineering Department.
