Abstract:
A method for operating and/or monitoring an HVAC system ( 10 ), in which a medium circulating in a primary circuit ( 26 ) flows through at least one energy consumer ( 11, 12, 13 ), the medium entering with a volume flow (φ) through a supply line ( 14 ) into the energy consumer ( 11, 12, 13 ) at a supply temperature (T v ) and leaving the energy consumer ( 11, 12, 13 ) at a return temperature (T R ) via a return line ( 15 ), and transferring heat or cooling energy to the energy consumer ( 11, 12, 13 ) in an energy flow (E). A control unit ( 21 ) adaptively operates the system by empirically determining the dependence of the energy flow (F) and/or the temperature difference ΔT between supply temperature (T v ) and return temperature (T R ) on the volume flow (φ) for the energy consumers ( 11, 12, 13 ) in a first step, and by operating and/or monitoring the HVAC system ( 10 ) according to the determined dependency or dependencies in a second step.

Claim (Index 17):
An adaptive variable flow Heating, Ventilation and Air Conditioning (HVAC) system ( 10 ), comprising:\n a primary circuit ( 26 ), which is traversed by the flow of an energy transporting medium, at least one energy consumer ( 11 ,  12 ,  13 ), which is connected to the primary circuit ( 26 ) by way of a supply line ( 14 ) and a return line ( 15 ), temperature sensors ( 16 ,  17 ) for determining the temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) at the energy consumer ( 11 ,  12 ,  13 ) as well as at least one flow sensor ( 18 ) for determining the volumetric flow rate (\u03c6) through the energy consumer ( 11 ,  12 ,  13 ), and a controller ( 21 ,  22 ) that is connected to the temperature and flow sensors ( 16 ,  17  and/or  18 ), wherein the controller ( 21 ,  22 ) receives and stores measurement values, which are outputted simultaneously by the temperature and flow sensors ( 16 ,  17  and/or  18 ), at different times, wherein dependence of the temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) on the volumetric flow rate (\u03c6) is repeatedly determined empirically at varying time intervals by the controller, and wherein, on the basis of the determined dependence, a lower limit value (\u0394T min ) of the temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) is established.
