1 OVERVIEW Demand-controlled ventilation Leading edge product for demand-controlled ventilation!

2 Demand-controlled ventilation offer great comfort and low operating cot When the room i in ue, ventilation and air conditioning i controlled to meet the need of the occupant. Demand-controlled ventilation involve ventilating and conditioning the air in a room or premie preciely to meet our need no more and no le. The potential for aving i ubtantial, epecially in premie uch a office, claroom and hotel room where there i coniderable variation between high and low load condition in room and during time when there are few or no occupant. Uing demand-controlled ventilation, it i poible to meet the ever-increaing requirement on energy efficiency. A much a 80% fan electricity and 40% of heating and cooling energy can be aved with demand-controlled ventilation compared with contant airflow and temperature. An empty room require minimum ventilation and air-conditioning. At the ame time, it give the opportunity for maximum comfort for the people occupying the premie through demandcontrolled heating and cooling regulation. Other poitive effect are that maller unit and dimenion can frequently be ued for ventilation, heating and cooling a the maximum airflow and air conditioning can be reduced compared with contant flow and temperature. Flexibility will alo be greater if wall are moved or converion are made in the future. The lightly higher invetment cot i quickly recovered through ignificantly lower operating cot.
