DEVICE AND METHOD FOR CONTROLLING THE OPENING OF A VALVE IN AN HVAC SYSTEM

For controlling the opening of a valve (10) in an HVAC system (100) to regulate the flow φ of a fluid through a thermal energy exchanger (2) of the HVAC system (100) and adjust the amount of energy E exchanged by the thermal energy exchanger (2), determined are the flow φ through a valve (10) and th...

Beschreibung
Zusammenfassung:	For controlling the opening of a valve (10) in an HVAC system (100) to regulate the flow φ of a fluid through a thermal energy exchanger (2) of the HVAC system (100) and adjust the amount of energy E exchanged by the thermal energy exchanger (2), determined are the flow φ through a valve (10) and the temperature difference ΔT=Tin−Tout between the supply temperature Tin of the fluid entering the thermal energy exchanger (2) and the return temperature Tout of the fluid exiting the thermal energy exchanger (2). The opening of the valve (10) is controlled depending on the flow φ and the temperature difference ΔT. For example, the opening of the valve (10) is controlled depending on a control criterion c=ƒ(φ,ΔT), calculated from the flow φ and the temperature difference ΔT.
