Building Thermodynamics

At the end of the course, students should be able to: 1. define and explain basic concepts of thermodynamics; and 2. state laws of thermodynamics.

Definition of essential terms, general concepts and Laws of Thermodynamics especially with respect to building services and systems. Definition and basic concepts of thermodynamics – system concept, open and closed systems. Flow and non – flow pressures. State of a system, properties of a system. Temperature, work and heat – the cycle. The first law of thermodynamics: mechanical equivalent of heat, corollaries of the first law. Energy equation (of the first law) and reversibility; work and reversibility, heat and reversibility, constant volume process, constant pressure process, polytrophic process, adiabatic process, isothermal process. The steady flow energy equation (of the first law); open systems with steady flow, nozzle and diffuser, turbine and compressor, throttling reciprocating compressor The second law of thermodynamics; cycle efficiency, the Clausius statement of the second law.
