我们提出了一种由光子驱动的量子吸收制冷机。该模型使用一个四能级系统作为其工作物质，并同时耦合到热、冷和太阳能热库。推导了制冷功率Q̇(C)和性能系数COP(COP)η(COP)的显式表达式，以揭示和优化器件的性能。我们的模型在紧耦合条件下运行效率最高，并且在极限T→0时符合热力学第三定律。
We propose a quantum absorption refrigerator driven by photons. The model uses a four-level system as its working substance and couples simultaneously to hot, cold, and solar heat reservoirs. Explicit expressions for the cooling power Q̇(c) and coefficient of performance (COP) η(COP) are derived, with the purpose of revealing and optimizing the performance of the device. Our model runs most efficiently under the tight coupling condition, and it is consistent with the third law of thermodynamics in the limit T→0.
