Course abstract

Students should obtain knowledge of right choose of heating, ventilation and air conditioning system elements, basic skills of design and calculation of simple systems, understanding of plant structures and content of project documentation.

Learning outcomes and their assessment

After course acquisition students must be able to make right decisions in assembling heating, ventilation and air conditioning system elements, calculations of them, to assess an consequences of wrong operation of systems, planning of right sequence of works, safety and quality control of works. Test1 • Knowledge about microclimate systems for residential buildings, their structure, components and preconditions for proper functioning; Test2 • Skills to calculate simple engineering systems , selection and calculation of main equipment and energy resources; Test3 • Competence in field of water, steam, air, gas, electric and heat pump heating systems of the buildings and ventilation. Test4

Requirements for awarding credit points

Students can pass an examination, when the course design project is developed and defended, all the tasks of the practical classes and 4 tests are fulfilled. In order to receive the cumulative assessment of the semester, 90 points must be obtained during the semester

Description of the organization and tasks of students’ independent work

After receiving an task of the independent course project, students need to get acquainted with the content of the assignment and the work plan. Drawings of the building should be checked in order to fully understand the building structure and division of premises. Students should study the normative literature and manuals required for the work. By completing an independent course project, students must acquire skills to make simplified calculations in the areas of heating, ventilation and air conditioning in buildings.

Criteria for Evaluating Learning Outcomes

Skills for practical use of theoretical knowledge in the design of heating, ventilation and air conditioning systems of the buildings - choosing the rational and effective solutions of the systems and the choice justification. Evaluation of capabilities to analyses the project solution. Skills to choose heating, ventilation and air conditioning solutions for specific buildings. Knowledge of the requirements of LBN and MK regulations in the areas of heating, ventilation and air conditioning: - LBN and MK regulations for heating, ventilation and air conditioning and knowledge of their changes. 1 p - participation in the lesson planned in the curriculum; + 1 p - if the given task is performed during the lesson; + 1 p - if you have to do the task independently and at high level during the lesson; 1 p - if a completed task is presented before or during the next session; + 1 p - if in the construction engineer notes we see qualitatively formulated task with calculation methodology and several calculation tasks; + 1 p or - 1 p for each question answered or not answered (student is entitled to receive 3 questions on each topic); 1 p - participation in the lecture provided; 1 p - if a summary of the lecture topic with additional information from the literature is presented; + 1 p or - 1 p for each question answered or missed on the subject of the lecture (student is entitled to receive 6 questions on the whole course); 50 p - for the course project which fully complies with the task and the requirements indicated in the methodological guidelines; - 1 p - for any missed requirement or error; + 1 p or - 1 p for each question defending the course project (the student is entitled to 6 questions). A student who acquires the discipline "Heating and Ventilation" completely independently has to present a construction engineer notes with all calculation methods and several calculation examples, correctly answer 3 questions on each topic, present a summary of lecture topics with additions from the literature, answer 6 questions about the whole lecture correctly. Student must develop a project that is fully relevant to the methodological guidelines and answer the 6 questions correctly, defending the course project.
