Abstract
In past few years there were a notable number of ventilation systems applications working with variable air volume (VAV). Accessibility, simplicity and low-cost of frequency regulation equipment implementation in ventilation systems using fans is raising energy efficiency of ventilation systems and their providence. A parallel view between conventional and VAV systems is presented in this paper. Transformation of average conventional into VAV system with minimum cost of adaptation possibility is analyzed. Energy efficiency of ventilation systems in non-residential facilities achieved with frequency regulated components is being part of project assignment and pretends to become important standard in ventilation systems design methodology.
Sažetak
U proteklih nekoliko godina je primetna sve češća primena sistema ventilacije koji rade sa promenljivim protokom fluida. Pristupačnost, jednostavnost i isplativost ugrađivanja opreme za frekventnu regulaciju ventilatora doprinela je povećanju energetske efikasnosti sistema ventilacije i njihovoj tehno-ekonomskoj isplativosti. U ovom radu je data paralela između dosad korišćenih konvencionalnih sistema i sistema sa promenljivim protokom. Takođe je analiziran način i mogućnosti prelaska starijih sistema na novi način regulacije u skladu sa trendovima, a opet uz minimiziranje troškova adaptacije. Energetska efikasnost sistema ventilacije primenom frekventno regulisanih komponenti sistema često biva sastavni deo projektnog zadatka i pretenduje da postane jedan od bitnijih standarda u projektovanju termotehničkih sistema i instalacija.
