Combining efficiency and reducing environmental impact. This is the challenge faced by many companies specializing in home appliances. While countries aim to achieve carbon neutrality by 2050, science is trying to change the paradigm of modern energy, which is viewed primarily in its cumulative dimension.
Chinese researchers recently announced that they have developed a cooling technology with unprecedented performance indicators, along with better environmental performance.

in study It was published on Thursday, February 1, in the journal Cell Reports Physical Sciences and was reported by the website interesting geometry, A team of scientists from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences has revealed the results of a first-of-its-kind thermoacoustic refrigerator (HDTR) experiment. This technology converts heat into electricity. But so far, its performance has been very poor.

Triple efficiency
Although environmental benefits are increasingly important, distributors first consider the effectiveness of the good. The latter, measured by the coefficient of performance, results in the difference between the cooling force at the outlet and the heating force at the inlet. This offering is integrated into the classic refrigerator circuits.

To improve the HDTR experience, the researchers attempted to remove the limitations of temperature adaptation by evoking a portion of the emitted acoustic energy. To do this, they applied different temperature conditions depending on the game.
The heating is set at 450°C, the motor is set at 35°C, and the cooling is set at 7°C. All these elements combined produced a result approximately three times more effective than previous experiments.
