Course abstract

The course is designed to introduce the principles and fundamentals of heating, ventilation and air conditioning (HVAC) systems as a part of any building or manufacturing processes for high quality product manufacturing in a properly controlled environment. HVAC systems are major energy consumers in the building industry. Course will develop an understanding: of how HVAC systems function in controlling temperature, moisture content in a conditioned space

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

During the semester, the student should prepare a report on the topic received at the beginning of the semester.

Description of the organization and tasks of students’ independent work

After receiving the topic of independent report, students have to prepare a table of contents of the report. Developing the report, students must acquire skills in collecting information available in the library and in Internet resources.

Criteria for Evaluating Learning Outcomes

At the end of the semester, students present and defend the reports, answers to the questions and the lecturer. Students' ability to develop presentation presentation, report quality, answers to questions and 4 test results are assessed.
