为了确定在热力循环中可回收的能源潜力 ,将其损失分为可避免和不可避免的损失 .通过内可逆卡诺循环传热温差引起的不可逆损失力学分析 ,提出了利用有限时间热力学来确定在热力循环中的不可避免损失的方法 ,推导出了确定工质和热源间的不可避免损失的计算公式 .利用推导的公式和平均温度的概念 ,可以对实际循环中由温差传热引起的可避免和不可避免的损失进行分析和计算 ,从而减少可避免的损失 ,以改进循环和提高循环的效率 .
In order to determine the potential of energy recoverable in the thermodynamic cycle, the loss of its energy is divided into avoidable and unavoidable losses.Through the analysis of the irreversible loss caused by the temperature difference of endoreversible Carnot cycle heat transfer, To determine the inevitable 在 loss in the thermodynamic cycle, and derive the formula to determine the inevitable 工 loss between working fluid and heat source.Using the derived formula and the concept of average temperature, Heat-induced avoidable and unavoidable losses are analyzed and calculated to reduce avoidable losses to improve circulation and improve efficiency of the cycle.
