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 7):
A method for adaptively operating and/or monitoring a Heating, Ventilation and Air Conditioning (HVAC) system ( 10 ) under control of a controller ( 21 ,  22 ), the method comprising:\n circulating a medium in a primary circuit ( 26 ), such that the medium flows through at least one energy consumer ( 11 ,  12 ,  13 ), the medium entering at a volumetric rate of flow (\u03c6) into an energy consumer ( 11 ,  12 ,  13 ) through a supply line ( 14 ) at a supply temperature (T v ) and leaving the energy consumer ( 11 ,  12 ,  13 ) at a return temperature (T R ) by way of a return line ( 15 ) and, in so doing, releases heat energy or cold energy to the energy consumer ( 11 ,  12 ,  13 ) in a flow of energy (E), empirically determining a dependence of the flow of energy (E) and/or a temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) on the volumetric flow rate (\u03c6) for the respective energy consumer ( 11 ,  12 ,  13 ), adaptively changing operation of the HVAC system ( 10 ) in accordance with the determined dependence and/or dependences, wherein the 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, whereby the volumetric flow rate (\u03c6) and the temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) are measured simultaneously at different points in time and, if desired, the associated flow of energy (E) is determined for each of these points in time from associated measurement values and assigned to a respective volumetric rate of flow (\u03c6) in order to determine empirically the dependence of the flow of energy (E) and/or temperature differential \u0394T between the supply temperature (T v ) and the return temperature (T R ) on the volumetric flow rate (\u03c6), while the system is running, over a sufficiently long period to time, wherein results that are obtained in each case are compared with each other by the controller, in order to determine by the comparison a degradation of the system in function or effect, and wherein the measurement values are scaled, in particular, by means of a mathematical model of the energy consumer ( 11 ,  12 ,  13 ) for purposes of comparison, or wherein other comparable measurements are used for comparison, when specified operating parameters have changed significantly in the meantime.
