热声系统具有非常吸引人的特点，在许多领域都有可能得到广泛的应用，特别是在制冷方面。具有工作恢复能力的行波热声发动机和行波热声制冷机的发明极大地提高了热声系统的热力学效率。为了充分利用行波系统的优点，设计并制造了一种行波可回收功的热声制冷机，该制冷机由行波热声发动机驱动，用于家用制冷。到目前为止，该系统的最低温度为−64.4℃，最低制冷功率为250W，−温度为22.1℃，氦气压力为3.0 Mpa，工作频率为57.7 Hz。系统的热输入为2.2kW。基于线性热声理论的模拟也与实验结果进行了比较，结果表明，在一定的压力波幅度范围和冷端温度范围内，模拟结果是合理的。
Thermoacoustic systems have very attractive features and possible wide applications in many areas, especially for cooling purposes. Inventions of traveling wave thermoacoustic engines and traveling wave thermoacoustic refrigerators with work recovery capability have greatly improved the thermodynamic efficiencies of the thermoacoustic systems. To fully utilize the advantages of traveling wave systems, a traveling wave work-recoverable thermoacoustic refrigerator has been designed and built that is driven by a traveling wave thermoacoustic engine, which is aimed at domestic refrigeration purposes. So far, the lowest temperature of −64.4°C and 250W cooling power at −22.1°C are obtained by the system with 3.0MPa helium gas and 57.7Hz working frequency. Heat input into the system is 2.2kW. Simulations based on linear thermoacoustic theory have also been done for comparison with experimental results, which shows reasonable agreement within a certain pressure wave amplitude range and cold end temperature range....
