Tiivistelmä
This thesis considers several important goals. The main purpose is to see how displacement ventilation sys-tem works in the lecture hall of M-building and compare obtained results with D2 and Indoor Climate Classi-fication. The second one is to analyze the function of the ventilation system. The last one is to realize when displacement ventilation is preferable to mixing ventilation.
Analysis of the system was carried out with instruments from MUAS HVAC laboratory. In lecture hall were measured temperature, relative humidity and CO2 concentration in the presence of nearly 50 people and also noise level, velocity and volume of air through the air supply diffusers. All the data are presented in tables and diagrams for easy viewing.
Based on these results it can be concluded that the displacement ventilation system is well suited for a lec-ture hall. People who are inside get the proper amount of fresh air right under their seats. All of this happens silently and keeps the temperature and relative humidity on wanted level. Air velocities does not exceed the permissible values.
