Academic year 2021/2022
Supervisor: Ing. Petr Kracík, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The main aim of this course is to acquaint the students with the problems of designing power units, its important hubs and possibilities of optimization.
Learning outcomes and competences:
The course enables graduates to process project documentation in power engineering including optimization thermal calculations.
Prerequisites:
Knowledge of Boilers and Heat Exchangers, Energy Sources and Transformation and Thermal Turbines I
Course contents:
The course continues the theoretical basics of the field obtained in the courses Energy Sources and Transformation, Boilers and Heat Exchangers and Thermal Turbines I. It focuses on planning and designing of power units, heat distribution (cooling) system and energy consumption. It includes optimization calculations of thermal diagrams and partial components of power plant and CHP plant with focus on economic aspects.
Teaching methods and criteria:
The course is taught in the form of lectures that have the character of explaining basic principles and theory of the mentioned discipline.
The calculation classes will be based around Open Source software OpenModelica. During the semester, video-lectures will be regularly released on University Moodle website. The videos will contain theory to each section and their implementation into the program. There will be individual assignments corresponding to covered topics. At the given scheduled time for the class there will be computer lab available, where individual consultations can take place.
Assesment methods and criteria linked to learning outcomes:
Credit requirements: active participation in seminars, submission of given project according to the set deadline.
Exam requirements: written part in the form of questions and numerical problems, oral part in the form of discussion on given topic.
Controlled participation in lessons:
The presence on lectures is recommended and will be delivered according to the schedule.
Calculation classes: submission of all calculation assignments
