Thermoacoustic driven refrigeration technology

2023-09-12 21:08:23
Foreword: Thermoacoustic refrigeration is a new type of refrigeration technology. In the past 20 years, many physicists and mechanical engineers all over the world are working on this new type of heat engine and cold machine based on thermoacoustic theory. Breakthroughs have been made both in theory and in engineering applications, and many studies have entered a practical stage of commercialization.
First, the advantages of thermoacoustic heat engine
Compared with traditional vapor compression refrigeration systems, thermoacoustic heat engines have unparalleled advantages: instead of using refrigerants, they use inert gases or mixtures thereof as working fluids, so they do not cause ozone layers in the CFCs and HFCs used. The damage and the greenhouse effect hazard; its basic mechanism is very simple and reliable, no need for expensive materials, and has great cost advantages; they do not require oscillating pistons and oil seals or lubrication, and the characteristics of no moving parts make their lifespan greatly extended. Thermoacoustic refrigeration technology almost overcomes all the shortcomings of traditional refrigeration systems and can be the development direction of the next generation of new refrigeration technology.
Second, the working principle of thermoacoustic device
The working principle of thermoacoustic devices: The working principle of all thermoacoustic products is based on the so-called thermoacoustic effect. The thermoacoustic effect mechanism can be simply described as adding heat when the sound waves are dense, and the sound waves are enhanced when the sound waves are sparse. When the sound waves are dense, heat is discharged, and when the sound waves are sparse, the sound waves are weakened. The actual thermoacoustic theory is much more complicated than this. Thermoacoustic devices are devices made using various energy conversion functions of thermoacoustic technology, including various heating machines and refrigerators, such as power engines using thermoacoustic technology, pulsating combustion, heat pumps, refrigerators, and mixer separators. It is a widely used type of device.
Third, the two directions of the thermoacoustic device
In general, thermoacoustic devices can be divided into two directions, one is a thermoacoustic engine, which converts thermal sound into acoustic energy, which is realized by self-oscillation; the other is a thermoacoustic refrigerator that uses sonic pump heat. To achieve refrigeration, the key is the phase matching of the sound field. Thermoacoustic refrigeration technology and thermoacoustic refrigeration are just an important branch of thermoacoustic technology and thermoacoustic devices.
