摘要

预冷策略，导致指数级更快的加热，是一种违反直觉的松弛现象，其中冷却系统在加热之前，它大大缩短了松弛时间。我们研究了马尔可夫系统在有限时间内作为奥托制冷机的性能，在循环加热过程之前包含预冷阶段。我们的研究结果表明，在奥托循环中加热过程之前的预冷通过显着提高机器性能和冰箱的稳定性来优化机器的性能。

Enhancing Otto refrigerator performance with a precooling strategy.

The precooling strategy, which leads to exponentially faster heating, is a counterintuitive relaxation phenomenon wherein cooling the system before heating it dramatically shortens the relaxation time. We investigate the performance of a Markovian system functioning as an Otto refrigerator for a finite time, incorporating a precooling stage before the cyclic heating process. Our results demonstrate that precooling prior to the heating process in the Otto cycle optimizes the machine's performance by significantly enhancing the machine performance and the stability of the refrigerator.
