| Recommended semester: 7th - 9th semester |
| Scope and form: Lectures, group work, exercises |
| Evaluation: Oral presentation and approval of reports
|
| Examination: 13-scale |
| Previous course: 77375 og 77588 |
| Prerequisites: 41311, 41814, 41815 |
| Aim: To introduce to the student the criteria and methods used for design of ventilation- and climatic systems, to choose components that promote low energy consumption and to determine strategies for control and operation of such systems. To enable the student to draw up and design indoor environments that satisfy human requirements. Special emphasis will be put on the calculation and measurement of airflow in spaces. |
| Contents: Load calculations. Processes in climatic systems. Components and types of system. Analysis of energy consumption. Strategies for operation and control. PC simulation of climatic systems, indoor environment and energy consumption. Ventilation principles and systems. Theory and modeling of isothermal and non-isothermal airflow in spaces. Airflow around humans. Heat transfer from humans. CFD-modeling. Comfort ventilation. Industrial ventilation. Natural ventilation. Hybrid ventilation. Infiltration. Measurement instruments. Measurement of airflow in spaces. Tracer gas measurements. |
Remarks: The course comprises lectures, group work and practical exercises in climate chambers.
During the course, the students will design a climatic system to a room that has well-defined requirements to the indoor environment. By PC-simulation, it will be tested if the system meets the requirements at an acceptable consumption of energy. By CFD-simulation, the resulting indoor environment will be described. The most advanced and precise methods for the measurement of air movement in spaces and the determination of air change rate and centilation efficiency by tracer gas are used to verify the designed and simulated indoor environment in practice. |
