In the final thesis we discused the comfort of a person being indoors and emphasized the effect of air turbulence on the perception of draught in a closed room. We described all the key factors that are a part of humans comfort in indoor environment. We also discussed PMV, PPD and draught models. An experiment, comparable to various experiments of scientists from the same field, involving 20 volunteers, demonstrated that the movement of the air noticebly affects human's thermal comfort. Then we graphically displayed the results and discussed it appropriately.
