三热源循环的Bucher图

THE BUCHER DIAGRAMS OF THREE-HEAT-SOURCE CYCLES

应用卡诺循环的Bucher图形象地表示出三热源循环,并由图中的相似三角形直接导出三热源循环的能量守恒方程、熵守恒方程和性能系数.

The Bucher diagrams of the Carnot cycle are used to present vividly three-heat-source cycles. The equations of energy and entropy conservations and the coefficients of performance of the cycles are directly derived from the similar triangles in the diagrams.
