カルノーサイクルとエネルギー効率について : 改善されたエネルギー変換理論とエネルギー効率について

抄録

In order to analyze the energy flow in the Carnot cycle, 3 concepts of the first law of thermodynamics are strictly applied. These are the law of conservation of energy, the equal treatment of all forms of energy regardless of form and the consecutive conversion of energy. For example, the energy supplied to the cycle is summed up not only heat energy but also other forms, and, the energy efficiency [η_EN] is adopted rather than the thermal efficiency [η_th] . As a result, it is shown that the energy efficiency of the Carnot cycle is a function of not only the higher and the lower source temperature but also the compression ratio in the isothermal process and it is zero when the compression ratio is 1.
