Design, Manufacturing Process, and Performance Testing of Thermoacoustic Refrigerator

Thermoacoustic refrigerator is one solution to climate change and global warming. Thermoacoustic cooling will reduce the damage to the ozone layer caused by refrigerants, but it is still very rarely used. Thermoacoustic equipment with PVC material was carried out in this research with the aim of obtaining a design for experimental research that is simple and can be measured according to the dimensional scale used but is comprehensive so that it can be used as a coolant. The method of designing a thermoacoustic refrigerator involves 3 stages. The first is making 3D parts, the second is the assembly process into a complete unit, and the third is the process of making working drawings as a guide for the manufacturing process. During the manufacturing process, all the components that make up the thermoacoustic refrigerator are placed according to the design drawing that has been created. So that all components of the thermoacoustic refrigerator can function optimally according to expectations. The temperature of CHX successfully decreases, and the performance test has been successful. The temperature drop at CHX within 15 minutes was 5.7°C, while at HHX, there was a temperature increase of 2.6°C.
