Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.
LEARNING OUTCOMES
After passing the course the student
- understands the concepts of ventilation and air-conditioning
- knows the most common ventilation and air-conditioning systems and their features
- can calculate the thermodynamic properties of moist air
- can calculate air flow rates on the basis of given criteria
- knows the ventilation ductwork sizing methods (e.g. static regain)
- can choose the supply air flow rate and temperature for a displacement ventilation system
- can calculate the unit processes and size the components of an air-conditioning system
- can analyze the operation of an air-conditioning system in practical problems
- can employ classical control algorithms in the control of air-handling processes

Assessment Methods and Criteria
Valid 01.08.2020-31.07.2022:
Learning assignments 100%
Applies in this implementation:
Each learning assignment consists of 2-3 exercises (i.e. computational problems) that are solved and reported appropriately. The reports are submitted individually via MyCourses.
Maximum score per assignment: 10 p (→ MAX 60 p). Passed (mark 1) = 50 % of the total score (= 30 p).
The submissions are assessed following the criteria below:
1.The submission is complete by the deadline. The student’s contribution is original and nothing gives a reason to suspect the student of plagiarism.
2.The final results are highlighted (e.g. bold, underlined, table) and they are correct.
3.Calculation procedures with assumptions, equations, substitutions (including units) and intermediate results are shown and appropriate.
4.Visualizations of the problem have been done when applicable, using standardized drawing symbols and practices. The system descriptions, graphs, figures, and schematic diagrams indicate that the problem has been understood correctly (i.e. the visualization adds value to the report).
5.The language (either English or Finnish) is good and easy to read. The terminology is correct. Good scientific reporting practices is followed, including references and citations, when applicable. If references are needed, they are listed in a separate reference list. All in all, the reporting should be brief and succinct and its appearance impeccable.
Workload
Valid 01.08.2020-31.07.2022:
Contact learning 12 h
Learning assignments 60 h
Other self-learning 48 h
Applies in this implementation:
One hour (1 h) of contact learning is assumed to include one hour (1 h) of student's own preparation.
100 pages of easy-to-read literature corresponds to 20 h of workload and 100 pages of difficult text 30 h of workload.
