Conventional compression refrigeration systems generate considerable noise and vibration. The noise results in serious, negative impacts on people. Thermoelectric refrigeration technologies are considered a potential way to overcome these challenges. A novel thermoelectric refrigeration system, wherein thermoelectric chips are coupled with ionic wind fans, is proposed. Its performance was experimentally investigated and compared with theoretical results. The actual operating noise of the thermoelectric refrigeration system is only 4.2 dB(A), which is much lower than the maximum noise value that does not affect sleep. From experiments under different operating conditions, the optimal operating voltage of the thermoelectric chip is 5.5 V at 283.15 and 313.15 K on the cold and hot sides. The maximum coefficient of performance (COP) values reaches 0.28 and 0.31, which are equivalent to those of a system coupled with mechanical fans. Additionally, an ionic wind fan has an optimal operating voltage of 10.8 kV to maximize its air supply efficiency. Notably, such an operating voltage might be distinguished from the optimal voltage that achieves maximum operational performance for the new system. When the operating voltage of the thermoelectric chip is 5 V, the optimal operating voltage to obtain a maximum COP of 0.31 is 11.1 kV. Moreover, the experimental refrigeration capacity is greater than 8 W. The new system shows the ultra-quiet ability to operate at a large refrigeration capacity, and has good potential in applications, such as advanced refrigeration, building air-conditioning and ventilation systems.

传统的压缩制冷系统会产生相当大的噪音和振动。噪音会对人们造成严重的负面影响。热电制冷技术被认为是克服这些挑战的潜在途径。提出了一种新型的热电制冷系统，其中热电芯片与离子风机耦合。对其性能进行了实验研究并与理论结果进行了比较。热电制冷系统实际运行噪声仅为4.2dB(A)，远低于不影响睡眠的最大噪声值。从不同工作条件下的实验来看，热电芯片的最佳工作电压为5.5 V，冷热侧分别为283.15和313.15 K。最大性能系数（COP ) 值达到 0.28 和 0.31，相当于带有机械风扇的系统的值。此外，离子风机的最佳工作电压为 10.8 kV，以最大限度地提高其送风效率。值得注意的是，这种工作电压可能与为新系统实现最大工作性能的最佳电压不同。当热电芯片的工作电压为 5 V 时，获得0.31最大COP的最佳工作电压为 11.1 kV。而且，实验制冷量大于8W。新系统在大制冷量下表现出超静音运行能力，在先进制冷、楼宇空调和通风系统等方面具有良好的应用潜力。
