Potencijal ventilacionog hladjenja u klimatskim uslovima Srbije

Apstrakt
Sveobuhvatno poznavanje lokalnih klimatskih karakteristika predstavlja osnovu za smanjenje potrosnje energije u sektoru zgradarstva, kao i izbegavanje skupih troškova rekonstrukcije objekata. Imajući to u vidu, integracija pasivnih strategija, poput ventilacije, zahteva detaljnu analizu klimatskog potencijala lokacije. Ova studija ispituje mogućnost primene prirodne i prinudne ventilacije kao pasivne strategije hlađenja u 18 različitih gradova Srbije. Softver Climate Consultant korišćen je za bioklimasku analizu u psihrometriskom dijagramu. Bioklimatski grafikoni su generisani projekcijom podataka o tipičnoj meteorološkoj godini (TMY) u psihrometrijski dijagram, uz integraciju komfornog opsega definisanog odabranim modelom termičkog komfora čoveka. Rezultati dobijeni ovom studijom pokazuju da klima u 18 razlicitih gradova pruža prirodan komfor od 7.1% do 15.7% vremena tokom godine, dok primena prirodne i prinudne ventilacije može povećati broj sati komfora na 12% do 25% ukupnog vremena. Zaključuje se da pridodna i prinudna ventilacija predstavljaju efikasne pasivne strategije hlađenja sa značajnim potencijalom primene u različitim klimatskim uslovima Srbije. Ovo može imati značajne implikacije za inženjere pri izboru kombinacije strategija hlađenja koje su odgovarajuće za određenu lokaciju.
