Aim
The aim of the course is to acquaint students with the special operating and design knowledge of energy equipment. Accordingly, multistage chillers, heat pumps, and absorption chillers are presented. Using a systems approach, they acquire methods for designing fuel cells, solar cells, and ORC circuits. Students will become familiar with the losses, characteristic curves, and modeling of the combustion process and heat loss used in 1-D modeling for internal combustion engines. Using a systems approach, they are familiar with the solutions used in gas engines, steam and gas turbines. Students can master the methods used to reduce sustainability and environmental impact.

Constantly monitors the own work, results and conclusions. Continuously expands the knowledge of energy equipment and processes. Open to the use of information technology tools. Seeks to learn about and routinely use the tools needed to solve energy equipment and processes. Develops your ability to provide accurate and error-free problem solving, engineering precision and accuracy. Applies the principles of energy efficiency, sustainability and environmental awareness in solving energy management tasks. Monitors changes in the social, economic and political system. Publishes the results results in accordance with professional rules. Publishes own opinions and views without offending others.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, student works with fellow students to solve tasks. With own knowledge, student makes a responsible, well-founded decision based on own analyzes. Feels a responsibility for the sustainable use of the environment and for present and future generations. Student is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
During the teaching of the subject, the lecture and practice are separated from each other, both in terms of content and methodology. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. Lectures include pre-published slide shows so students can add their own notes to the lecture. The lectures are the main (on-line) available written study materials, they are not enough to achieve the appropriate preparation. Independent practical sessions with the theme related to the lectures and the method of the mirrored classroom promote the application and skill-level acquisition of knowledge. During the exercises, the knowledge previously acquired at home, independently, is solved partly jointly and partly individually with the help of the practice leader. Some of the exercises are held in the lab, where students deepen their theoretical knowledge through demonstrations.

General rules
Summative assessments collectively examine and assess students ’learning outcomes defined by knowledge-type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge, the existence of knowledge and the application of skills. In the course of partial performance assessment, we assess the application of knowledge acquired at practical classes and the acquisition of skills and the application of skills, which take place as a function of the progress of the exercises. The condition for completing the course is a result of at least 50% of each of the evaluations.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 3 | |
| Purpose, description: | Summative assessments collectively examine and assess students ’learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge. They will be completed at a pre-announced date specified in the academic performance assessment plan. Each of the 3 summary performance evaluations can be awarded 25 points. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | The basic aim of the partial performance assessment is to examine the existence of attitudes and learning outcomes belonging to the autonomy and responsibility competence group. Partial performance assessment measures the application of knowledge, skill level acquisition and skills acquired in the sessions. This will depend on the progress of the exercises. During the partial performance evaluation, 4 laboratory reports must be submitted. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 75 % |
| Mid-term assessment No. 2 | 25 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 72 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 72 % |

| the summative assessments can be retaken or improved only combined | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| one single, combined retake or grade-improving exam is possible for all assesments | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| out of multiple results, the best one is to be taken into account | ||
