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 24):
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 flow of energy (E) and/or 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 results that are obtained in each case are compared with each other by the controller, in order to determine by means of the comparison a degradation of the system in function or effect.
