CALCULATION OF THE VENTILATION RATES FOR THE KITCHEN AND BATHROOM According to Category II exhaust air flow in kitchen is 20l/s and in bathroom 15 l/s. Amount of bathrooms and kitchens-9. Bathroom area- 5,3-6,9m² 15 × 9/9·6=2,5 l/s Kitchen area-15m² 20 × 9/9·15=1,3l/s CALCULATION OF THE AIR EXCHANGE RATE IN ONE APARTMENT.
It assumed that 4 people live in the apartment and 8 people work there, according to the given tables such people loads were chosen: adult - 1 olf; children - 1, 2 or 1,3 olf depending on age building material load- 0,2 olf c=1,4 the experienced air quality is determined on the background of the PD (PD is percentage of dissatisfaction) ci=0,05 represents the level of pollution in cities q=(1 olf ·10) + 1,2 olf +1,3 olf + 0,2×78=28,1 olf Vl=10·28,1/ (1,4-0,05)=208 l/s =2,5l/s per m² n=208×3600/ 234000=2,39 h-1 Using date obtained from BSim, air exchange rate was calculated again, to see the maximum rate in relation to the amount of openings. Result from BSim, maximum air exchange rate is in June n=3,8 Vl=1000·234·3,8/3600=247 l/s = 3,4l/s per m2
