• Thermal Power Engineering, Semester 3, position 3

Getting knowledge and skills in air conditioning - various central air conditioning systems; mastering methods for calculating air ducts, choosing elements for intake and extract of air, and using those methods in air conditioning project design.

Upon successful completion of the course, students should be able to: • Select the appropriate elements for supply air inlet in the air-conditioned room in order to achieve optimal air distribution in space • Apply of different methods for the calculation of pressure drop in air ducts • Explain the basic features central air conditioning systems (all air and air to water systems) • Apply measures to increase energy efficiency of the air conditioning systems • Estimate of the advantages and disadvantages of different systems for ventilation and air conditioning • Apply their knowledge to solving practical problems in air conditioning development, design and installation • Be efficient in team work

Air distributing elements; duct calculation methods; air distribution; airflow range; air inlet and extract position; air conditioning systems - classification; central single-duct low pressure system with constant air volume, zone air conditioning systems; high pressure air conditioning systems: with constant and variable airflow rate; air to water air conditioning systems; induction unit; two pipes systems change over and no change over; three-pipe and four-pipe systems; hydronic systems with fan coil units; combination with ventilating systems, local air conditioning systems; compact and split systems; energy efficiency of ventilation and air conditioning systems.

Auditory is composed of more sections, in order to complete project design. Design and regulating air conditioning systems, calculating energy consumption and using waste heat. Laboratory consists of measuring airflow in ducts and distributive elements, regulating air conditioning systems, measuring airflow range and intermediate operating mode. Visit to Thermal science exhibition in HVAC congress or to factory for air conditioning equipment is planned.

In order to attend subject it is required to pass the exam: Air Conditioning Fundamentals.
