What does it mean to grasp an object and feel it to be “cold?” You aren’t gaining cold; you are losing heat as it transfers out of you and into the object. Likewise, air conditioners transfer heat out of rooms and refrigerators transfer heat out of food. Most refrigerators and air conditioners are vapor compressors, meaning they transfer heat by compressing a toxic substance called refrigerant, which rapidly condenses and evaporates. This project demonstrates a simpler and cheaper method of heat transfer using thermoacoustics. Thermoacoustic refrigerators (TAR) have been researched for decades but only used in niche applications like onboard the Space Shuttle. We hope that our findings can drive commercial development. Our TAR has 4 main components: transducer, resonator, stack, and heat exchangers. The transducer is a loudspeaker that generates a standing wave inside a PVC pipe resonator. The stack is a plastic 3D-printed cylinder with internal parallel plates. A phenomenon called the “Brayton cycle” uses the sound waves to pump heat and generate a temperature gradient across the stack, making one end cold and the other hot. The cold heat exchanger brings in air that needs to be cooled and transfers heat from it into the stack, while the hot heat exchanger cools down the hot end of the stack. The actual sound waves at the stack are disrupted by the resonator tube, heat exchangers, and the stack itself. This decreases the slope of the temperature gradient. Some research has been done on the effects of different speaker input waveforms (sine, square, triangle, etc.) but not on cancelling out the disruption. Therefore, we will use signal processing to find the proper speaker input waveform that corrects this disruption. Our MATLAB simulations and theory lead us to expect that this should generate a steeper gradient and thus better cooling.
