HEAT RECOVERY OF VENTILATED AIR IN AN EXISTING EDUCATIONAL BUILDING IN THE CITY OF DOBOJ

Abstract

This research is related to ventilated air heat recovery. The analysis includes the heat recovery of air in cases when ventilation is defined according to the air changes per hour and according to the current presence of people in the ventilated zones. The research was conducted for an existing nonresidential (educational) building in the city of Doboj. The large heat losses through the ventilation system can be reduced by installing an energy recovery ventilator. Analysis of the presence of people in the zones can have a major impact on the operation of the ventilation system and electricity consumption. It is assumed that the dependence on these two factors is very important and that the study could be a starting point for solving this problem in a given area. The analysis was conducted in the software EnergyPlus.
