Definitions

  • the invention relates to a heating system according to the preamble of patent claim 1 and a method for operating a heating system according to the preamble of patent claim 5.
  • a heating system of the type mentioned and a method for their operation are known for decades, d. H. To this extent, no special documentary evidence is required.
  • Such a heating system consists of a heater for heating a fluid heating circuit medium (usually water), wherein the heater via a feed and a return port is hydraulically connected to a heating circuit medium leading and having a plurality of heating radiator heating circuit.
  • the radiators also called heating surfaces
  • the radiators are parallel or serially involved in the heating circuit (or the heating circuits).
  • each heating surface In order to provide a rated heat output, each heating surface must be supplied with a nominal volume flow of the heating circuit medium.
  • radiators with greater power require a larger heating medium flow rate than heating surfaces with lower heat output.
  • each radiator has a typical for him pressure loss between its inlet and outlet, d. H. a radiator with a smaller pressure loss is regularly fed more heating circuit medium than a radiator with greater pressure drop. In practice, this problem is addressed by the so-called “hydraulic balancing" of the system, which is intended to ensure that each radiator receives the nominal volume flow of heating circuit medium intended for it.
  • VOB Utility-to-distance heat
  • a flow meter is known on a radiator, which is used to determine the volume flow to the radiator and thus ultimately to carry out a hydraulic balancing.
  • the invention is based on the object in a heating system and in a method for operating a heating system of the type mentioned to improve the hydraulic tunability of the components to each other or simplify the task.
  • the heater for performing a hydraulic balancing of the heating system is provided with means for detecting and displaying the heater provided by the heating medium flow rate and means for detecting and displaying the pressure difference between the supply and the return port.
  • the heater is already equipped ex works with two measuring devices (for pressure and flow measurement), with the help of a hydraulic adjustment of each time and indeed without further special measurement setup is possible.
  • two measuring devices for pressure and flow measurement
  • This balancing takes place with the heating system according to the invention in that in a first step, that radiator is determined (by measurement), which at its nominal volume flow (ie the volume flow to which the radiator is designed) and in single mode the largest pressure difference between and return connection causes that are decoupled in a second step, all except for the determined radiator from the heating circuit and for the determined radiator at nominal flow rate which is determined between flow and return port pressure difference is determined, and that in further steps, one radiator after the other each alone and at nominal flow rate by adjusting a throttle body provided on the throttle device is adjusted such that each set the determined in the second step pressure difference between the flow and return port.
  • the required nominal volume flow of the heating circuit is determined during hydraulic balancing with a means for detecting the volume flow, and that after carrying out the hydraulic balancing, the power of the heating circuit pump is adjusted such that the determined nominal volume flow exactly reached.
  • the information obtained about the required volume flow during hydraulic balancing is used according to the invention for setting the optimum pump performance.
  • the means for detecting the volume flow can be arranged both on the heater itself (see also claim 1), but also on the individual radiators (see claim 3). It is essential that the heating circuit pump according to the invention provides exactly the capacity that is actually required, that is, the adjustment of the pump power according to the invention is no longer simply by estimation.
  • the one in the only one FIG. 1 illustrated heating system consists of a heater 1 (typically an oil or gas boiler, but also solid fuel boiler or the like) for heating a fluid heating medium, wherein the heating control 1 2 having a heater 1 via a supply and a return port 3, 4 hydraulically with a heating medium leading and multiple radiator 5 having heating circuit 6 is connected.
  • a heater 1 typically an oil or gas boiler, but also solid fuel boiler or the like
  • the heating control 1 2 having a heater 1 via a supply and a return port 3, 4 hydraulically with a heating medium leading and multiple radiator 5 having heating circuit 6 is connected.
  • the heater 1 for carrying out a hydraulic adjustment of the heating system with means 7 for detecting and also displaying the provided by the heater Bankniklaufmedium volume flow (preferably a volumetric flow meter or means for calculating the volume flow based on other measurements) and with Mittelr. 8 for detecting and also displaying the pressure difference (preferably a differential pressure gauge or a device for calculating the pressure difference based on other measured values) between the supply and the return port 3, 4 is provided.
  • the radiator 5 is determined which causes the largest pressure difference between the supply and return port 3, 4 at its nominal flow rate and in standalone mode (ie selection of the radiator), that are decoupled in a second step, all except for the determined radiator 5 from the heating circuit 6 (ie turn or continue to operate alone) and for the determined radiator 5 at nominal volume flow between the supply and return port 3, 4 resulting pressure difference is determined (ie, measurement of the pressure difference for the selected radiator), and that in further steps a radiator 5 after another in each case alone and at nominal flow rate by adjusting a radiator 5 provided on the throttle device 9 is adjusted such that in each case the in the second Sch Rode determined pressure difference between the supply and return connection 3, 4 sets.
  • a means 10 for detecting the radiator 5 flowing through the heating circuit flow rate is further provided on each radiator 5, said means 10 for passing the determined volume flow information (for example, by data line, but preferably also by wireless transmission [radio, etc.]) is connected to the heating control 2. Thanks to this connection between the volume flow detection means on the radiator and the heating control 2, which is simultaneously connected to the central means 7 for detecting the volume flow of the heating circuit, influencing the volume flow measurement can be omitted by the sole operation, since a possible deviation between the two detection means 7, 10 of the heating control 2 or a user of the system would immediately notice. Thus, these additional volume flow sensing means serve to further eliminate errors in and also automate hydraulic balancing (s).
  • each radiator 5 has a throttle device 9 (already mentioned above) and a thermostatic valve 11.
  • the throttle device 9 is used to establish an always-acting pressure loss at the radiator 5 (namely, exactly the pressure loss, which is determined and adjusted during hydraulic balancing);
  • the thermostatic valve 11 serves to adjust the currently desired heating power of the radiator 5.
