Fundamentals of power and energy transfer equipments

After the study of this discipline the student must have knowledge of several aspects of renewables energies and energetic sustainability, especially on the principles and equipment used for heat and work transfer from the different resources, that is not approached in the Grade studies.
This discipline provides knowledge of thermodynamics and energy transfer (as heat and work) to the student, as well as energy balances of such systems. That allows the student to analyze and design the equipment commonly used in the field of energy, especially for renewable energy and energy efficiency.
First the students will learn the principles of thermodynamics to define a system, its energy and forms of energy, and the energy transfer by means of heat and work. Later, the students will learn the heat engines and thermodynamic cycles related to equipment that will be studied ahead and in other modules. The students will learn the equipment for energy transfer such as boilers, evaporators, vaporizers, refrigeration, furnaces, burners, among others. Besides they will learn equipment for work production, such as compressors, pumps and others. With this knowledge the students will learn the application of energy balances to an equipment or a combination of them in order to calculate energy needs for design and characterization. In the last part of the discipline the students will learn the mechanisms for heat transfer (conduction, convection, radiation), the equations governing them, and they will be applied to different equipment for heat transfer, with special attention to heat exchangers, their types, selection, calculation and design. Last, the students will learn what are co-generation systems and the design of different configurations.
The students will be able to recognize, calculate and design equipment and systems for energy transfer and their parts, also using energy efficiency criteria. Once finished the discipline, the students will have a basis of energy production and transformation to be used in disciplines of the following modules. In this discipline is not included electric work and the corresponding equipment.
