Description
スターリングエンジン等の熱機関の効率であるシステム効率は、熱交換器効率とサイクル効率（理論熱効率）の積で表される。熱交換器効率は、熱機関に供給される高温熱源の入口温度と出口温度の差を入口温度で除することによって算出される。サイクル効率は、熱機関が利用する理論サイクルによって定まる値である。スターリングエンジンは、カルノーサイクルを利用した機関であり、カルノーサイクルはサイクル効率が高く、ランキンサイクル等に比べて有利であることが知られている。しかしながら、従来のスターリングエンジンでは、より高いカルノー効率を得るために、高温側作動ガス温度を上げると共に、入口温度と出口温度の差を小さくする手法が採られる。その結果、スターリングエンジンは、出口温度以下の熱量を捨てることになり、熱交換器効率が小さくなるという問題がある。そのため、スターリングエンジンは、熱交換器効率がランキンサイクル等と比べて著しく小さいという問題がある。
The system efficiency, which is the efficiency of a heat engine such as a Stirling engine, is represented by the product of the heat exchanger efficiency and the cycle efficiency (theoretical thermal efficiency). The heat exchanger efficiency is calculated by dividing the difference between the inlet temperature and the outlet temperature of the high temperature heat source supplied to the heat engine by the inlet temperature. The cycle efficiency is a value determined by the theoretical cycle used by the heat engine. A Stirling engine is an engine that uses a Carnot cycle, and the Carnot cycle has a high cycle efficiency and is known to be more advantageous than a Rankine cycle. However, in the conventional Stirling engines, in order to obtain a higher Carnot efficiency, Rutotomoni raising the Atsushi Ko side working gas temperature, a technique to reduce the difference in inlet and outlet temperatures are employed. As a result, the Stirling engine has a problem that the heat quantity below the outlet temperature is discarded, and the efficiency of the heat exchanger is reduced. Therefore, the Stirling engine has a problem that the efficiency of the heat exchanger is significantly smaller than that of the Rankine cycle.
