Course objectives:
Principle of left-handed processes; cooling and heating mode of heat pump; application of renewable energy sources in heating and cooling systems using heat pumps; measurements on the real heat pump systems; energy analyses, seasonal performance factor, economy analyses
Student responsibilities:
Grading and evaluation of student work over the course of instruction and at a final exam:
Appropriate attendance of classes (meaning both, lectures, exercises, measurements) and student"s feedback will constitute 30% of the final mark, while the outcome of the home works and oral presentation of the seminars will account for the rest (70%).
Methods of monitoring quality that ensure acquisition of exit competences:
Interactive work with student during lectures and seminars. Consultations during preparation of final project.
Upon successful completion of the course, students will be able to (learning outcomes):
After successfully completing the course, the student will be able to to verify theoretical and practically applicable knowledge about heat pumps as high efficiency system for heating and cooling using renewable energy sources, to establish the calculation of heat pumps in heating and cooling mode, to establish calculation of the ground source heat pump (air to water heat pump) according to standard HRN EN 15316-4-2, to compare the heat pumps with conventional heating and cooling systems, to implement the practical works on the real test systems (air source heat pumps, ground source heat pump and solar assisted heat pump) in the lab of Applied thermodynamics, to recommend optimal design of the thermotechnical heat pump system.
