Abstract

A common belief is that any closed, counterclockwise cycle on a pV diagram represents a refrigerator or heat pump. It has been established that this is not the case, but previous papers on this topic have made unnecessary assumptions about the temperatures of the energy reservoirs and about how the system exchanges energy with the reservoirs. Relaxing these assumptions leads to a wide array of unexpected behaviors. In some cases, the same pV cycle can be a heat pump, a cold pump, or a Joule pump simply by changing how the system is connected to the reservoirs. This paper explores the strange world of counterclockwise cycles.
探索逆时针热力学循环
人们普遍认为,PV 图上任何封闭的逆时针循环都代表了冰箱或热泵。事实证明并非如此,但之前有关这一主题的论文对储能器的温度以及系统如何与储能器交换能量做出了不必要的假设。放宽这些假设会导致一系列意想不到的行为。在某些情况下,只需改变系统与储能器的连接方式,相同的光伏循环就能成为热泵、冷泵或焦耳泵。本文将探讨逆时针循环的奇特世界。

期刊介绍: The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
