Definitions

  • the invention relates to a device and a method for hydraulic balancing of radiators or heating circuits of surface heating of a hot water heating system.
  • each room of the building is supplied with the previously calculated amount of heat through the radiator installed there or the surface heating installed there. If such a hydraulic balancing is not carried out, then those radiators or heating circuits, which are closer to the pump of the heating system, heated more than the more distant radiator or heating circuits. This allows the radiators or heating circuits in the more distant rooms only bad rules. It can also happen that these rooms can not be supplied with sufficient heat at all.
  • the return temperature is relatively high, since the return of the entire heating system consists primarily of the return water of the first radiator. Too hot a return can cause the pump or burner of the heating system to be switched off prematurely.
  • Hydraulic balancing has hitherto been carried out primarily by presetting thermostatic valves to restrict the flow to the radiators or to the heating circuits. Hydraulic balancing can also be achieved via return flow control valves or with the aid of pressure-controlled flow pumps.
  • the present invention is therefore based on the object to provide a way with which a hydraulic balance of a heating system in a simpler and more verifiable verifiable manner than before can be made.
  • the object is achieved by a device for hydraulic balancing of radiators or heating circuits of surface heating of a hot water heating system with a mass flow sensor which can be installed in the flow or in the return of the radiator or heating circuit.
  • the mass flow of each radiator can be measured exactly and adjusted to the desired value either on the thermostatic valves or on the return throttles of the radiators or heating circuits. Working with manufacturer diagrams can be omitted. In addition, a control of the mass flow of each radiator or heating circuit is also possible at any later time.
  • the total mass flow of the heating system is reduced.
  • the heating pumps can run at lower power. As a result, electrical energy for operating the heating system can be saved.
  • the mass flow sensor may preferably have a flow sensor which can be installed in the flow or return, the measurement signals of which are provided by a flow sensor can be read externally connected to the device evaluation unit and can be converted into a mass flow.
  • Flow sensors are known in different configurations. Frequently used, for example, ultrasonic flow sensors, differential pressure sensors or magnetic-inductive flow sensors.
  • the latter category includes turbine wheel flow sensors, which may preferably be used in the device according to the invention. In these sensors, the rotational speed of the turbine wheel can be detected contactlessly via a magnetic coupling or an induction coil from the evaluation unit.
  • the non-contact readout makes it possible to dispense with mechanical connections to the outside. There are thus no leakage problems on the device.
  • the rotational speed of the turbine wheel of each of the devices can be converted into a mass flow.
  • the speed of the turbine wheel behaves proportionally to the flow velocity, whereby the flow rate can be determined.
  • the mass flow is the product of the flow rate and the density of the heating fluid, d. H. usually from water.
  • the device also has a temperature sensor.
  • the return temperature can be detected with this temperature sensor.
  • the mass flow of the radiator or heating circuit can also be adjusted to influence the return temperature.
  • the device is designed in the form of a pipe piece, in which the mass flow sensor is installed.
  • the pipe section can be easily installed in the flow or return of a radiator or heating circuit. It is particularly advantageous if a turbine wheel flow sensor is provided and the turbine wheel is arranged in a central portion of the pipe section, which has a smaller inner diameter than the subsequent outer sections. By taking advantage of the Venturi principle, the turbine wheel rotates quickly, even at low flow rates, ensuring sufficient measuring accuracy.
  • the device may preferably be installed between a radiator or heating circuit and a return throttle. During the reading of the mass flow, the mass flow can then be set to the desired value parallel to the return throttle.
  • the invention also relates to a method for hydraulic balancing of the radiator and / or heating circuits and surface heating of a hot water heating system, which is characterized in that in the flow or return of each radiator and / or heating circuit, a device according to the invention is installed and the flow resistance of each radiator and / or heating circuit is set such that the mass flow measured with the devices corresponds to the desired heating power of the respective radiator or heating circuit.
  • the flow resistances can be adjusted either by presettable thermostatic valves in the flow and / or by means of return throttles. If the devices are installed in the return, there is the advantage that the measurement of the mass flow and its regulation by the return throttle take place directly adjacent to each other.
  • the flow resistances are additionally set in such a way that the return temperatures of all radiators and / or heating circuits are in the condensation temperature range of a burner of the heating system. If a burner is operated in the condensation temperature range, additional energy savings can be achieved.
  • the device according to the invention and the inventive method is used to simplify the hydraulic balancing a heating system, in addition, a much higher precision than with manufacturer diagrams is achieved.
  • the devices according to the invention can also be retrofitted at any time to existing radiators and / or heating circuits of a heating system.
  • a radiator 10 is shown with a thermostatic valve 11 in a flow 12. About the flow 12 of the radiator 10 is heated by a burner, not shown here, a heating system. This water flows through the radiator 10 and leaves it on a return line 13 again.
  • a device 14 according to the invention for hydraulic balancing is arranged, which is screwed directly into the heating element 10, such as Fig. 2 clarified.
  • a return throttle 15 is provided, with the help of which the water flow through the radiator 10 is adjustable. With the device 14, however, the flow and thus the mass flow of the radiator 10 can be measured.
  • the device 14 allows checking the setting of the flow by means of the return throttle 15th
  • the device 14 is in Fig. 2 shown in an enlarged view in longitudinal section. It consists essentially of a pipe section 16 which is screwed by means of a thread 27 in the radiator 10. Inside the pipe section 16, a turbine 17 is arranged, which is rotated by the return water in rotation. The effluent from the pipe section 16 water enters the return throttle 15, which is screwed into the pipe section 16. At the output of the return throttle 15, a return pipe, not shown here, can be screwed into a threaded bushing 18 provided for this purpose. For detecting the rotational speed of the turbine 17, an evaluation unit 19 is arranged on the outside of the pipe section 16. This determines the speed of the turbine 17 contactless.
  • the turbine 17 may be equipped with magnets and be provided in the evaluation unit 19, a Hall sensor, which converts the speed of the turbine 17 into a pulse signal.
  • the turbine 17 may be equipped with electrically conductive elements or made of an electrically conductive material.
  • the evaluation unit 19 can then integrate an induction coil, which also generates from the rotational speed of the turbine 17, a pulse signal having a frequency which depends on the rotational speed of the turbine 17. From the speed can be calculated with a known cross-section of the pipe section 16, the volume flow of the radiator 10 and from the mass flow. These calculations can also be made by the evaluation unit 19.
  • the required mass flow from the heat demand calculations for the room in which the radiator 10 is placed known. If the evaluation unit 19 displays a value deviating from the desired mass flow, the flow resistance of the heating element 10 can be increased or reduced via the return throttle 15 until the mass flow which is permanently measured by the evaluation unit 19 reaches the desired value.
  • the evaluation unit 19 can be removed from the pipe section 16 and used to determine the mass flow of similar devices 14 to other radiators 10 or heating circuits of surface heating.
  • the evaluation unit 19 is shown here with a power cable 20 for power supply. However, it could also be a battery powered unit. A mains connection to their operation would then not be required.
  • Fig. 3 shows an alternative embodiment of a device 14 'for hydraulic adjustment of the radiator 10.
  • the device 14' consists of a pipe section 16 ', which by means of a thread 27' in the radiator 10 can be screwed.
  • the pipe section 16 ' has a flow channel 21 with a substantially smaller diameter than the pipe section 16.
  • the inside of the Flow channel 21 arranged turbine 17 ' thus rotates much faster than the turbine 17.
  • the device 14' is therefore particularly suitable for radiators with relatively slowly flowing water. Due to the narrowing of the cross section in the passage 21, the measuring sensitivity of the device 14 'is significantly increased.
  • An evaluation unit 19 'for detecting the rotational speed of the turbine 17' and for calculating the mass flow can also be attached to the device 14 '.
