Heat engines and reversed heat engines (refrigerators and heat pumps) are studied through idealised cycles such as the Carnot cycle. Efficiency and coefficient of performance are derived and compared. The syllabus also addresses practical modes of heat transfer—conduction, convection, and radiation—and uses appropriate constitutive equations, like Fourier’s law for conduction. Sustainability and renewable energy sources are discussed in this context.
通过理想循环（如卡诺循环）研究热机和逆向热机（制冷机和热泵）。推导并比较效率和性能系数。大纲还涉及热传递的实际方式——传导、对流和辐射——并使用适当的本构方程，如热传导的傅里叶定律。在此背景下讨论可持续性和可再生能源。
η_Carnot = 1 – T_C / T_H (temperatures in kelvin)
卡诺效率 = 1 – 低温热源温度 / 高温热源温度（温度单位为开尔文）
11. Engineering Design and Project Management | 工程设计与项目管理
Design is a recurring theme throughout the course.
