一、水蒸气:火力发电、核电、 二、低沸点工质:氨、氟里昂太阳能、余热、地热发电、 三、动力循环:以获得功为目的

定理:在两个不同温度的恒温热源间工作的 所有热机,以可逆热机的热效率为最高

空气流经某些可逆过程后分成两股,如 下图设在这些过程中可以与空气流进行热 量交换的热源只有一个。试确定这些过程中 空气流与热源之间的净传热量Qnt以及与外 界之间传递的净功量Wnao为了实现上述方 案,具体过程应该怎样安排?

三种不同品质的能量 1、可无限转换的能量(Ex) 理论上可以完全转换为功的能量高级能量 如:机械能、电能、水能、风能 2、不能转换的能量(An) 理论上不能转换为功的能量如:环境(大气、海洋) 3、可有限转换的能量(Ex+An) 理论上不能完全转换为功的能量低级能量如:热能、焓、内能
