Definitions

  • the invention relates to a method for hydraulic balancing a hot water heating system, which (at least one) Circulation pump and several radiators, the Radiator with an adjustable flow valve, a flow-adjustable return valve and one lockable ventilation opening are provided.
  • the object is achieved by the invention, a method for to create hydraulic balancing of a heating system and to be designed in such a way that the desired pressure difference in thermal calculations controllable and verifiably adjusted.
  • This can be achieved, the hot water heating systems energetically to be able to operate particularly economically in order to use less energy consume and thus reduce the environmental impact.
  • the controllability of the upcoming technical values an optimization of the system function reached.
  • the pressure difference on the radiator for the maximum flow volume flow Help of the already existing or to be installed Return valve set.
  • This setting is always with fully opened inlet valve (thermostatic valve).
  • the size of the volume flow is below the maximum value then determined by the thermostatic valve.
  • a default on Thermostat valve is therefore generally no longer required, but in certain cases may be additional be provided.
  • For the return valves it is recommended especially in new buildings, to choose a construction that will their throttling behavior the most accurate setting possible favored.
  • measurements are made directly on the respective Radiator done.
  • the possible measuring location ranges from Inlet valve to the return valve.
  • This is Have fixed measuring devices used or the Mount measuring devices for the purpose of the respective measurements or can be dismantled, it is preferred according to the invention, firmly installed measuring connections to be provided for the the connection of the measuring device can be used.
  • firmly installed measuring connections to be provided for the the connection of the measuring device can be used.
  • Such a demand measurement connection is made according to the invention in particular instead of the usual vent plugs the radiators provided and used.
  • a accordingly designed manually operated ventilation and Measuring connection valve there are simple possibilities for Venting, pressure relief, filling and measurement on everyone Radiator.
  • the connections can be self-opening at Connect and self-close when disconnecting Venting and / or measuring devices. Therefore allow such valves a simple, clean, quick and safe How to use the adjustment procedure without to shut down the system.
  • Such one Connection is in EP-99104565.9 by the same applicant described.
  • the invention provides an exact, measurable setting of the specified differential pressure ⁇ p on each individual radiator enables. So the hydraulic balancing can be carried out so that, when used as intended, all Heat consumers according to their heat requirements with heating water be supplied.
  • the setting values of the respective String controls are measured and monitored. Over a There is a measuring point for each line, floor or residential unit Possibility of the desired values for the string regulation adjust, review, monitor and each adjust the connected radiator individually.
  • Throttle point as constant throttle or constant set Throttle point is parallel to the rest of the system and one Current division in the system and physical Fact that liquids are always the way of the least Resistance is a flow adjustment through the Setting the pressure difference via the constant throttle point possible if a second adjustable throttle point with the constant throttle point is connected in series. This This also occurs with heating systems.
  • the Return valves RLV are still adjusted, the Setting to the exact or desired flow value is simple and controllable.
  • the flow rate of the individual radiators adjust that the cooling of the heating water in the upper Floors can be taken into account by the Throughput to a somewhat higher value with these radiators
  • procedure I all measurements are made for the desired pressures and to set the pressure difference on single radiator over a single measurement and Vent connection, which instead of the usual Vent plug is used.
  • the first comparison should Basically preferably in a cold system, when the system is closed Mixer and running pump are carried out.
  • the Setting value for the pressure difference is obtained by subtracting the desired ⁇ p calculated from the inlet pressure and with constant Control set by the pressure measurement on the return valve.
  • Thermostat valves may also have a different basic setting, but which would have to be documented so that the starting position is repeatable.
  • the procedure described does not only include that Hydraulic balancing process by adjusting the Pressure difference ⁇ p on the individual radiator, but also offers the possibility by appropriate measurements or simple Calculations of the overall hydraulic function of a To be able to assess the heating system.
  • the setting of the pressure difference on the individual radiator is namely depending on the constancy of the inlet pressure before the Consumers during the setting process.
  • the first comparison should preferably be used in cold systems closed mixer and running pump. Since the inlet pressure is an important control variable for the Plant function, it may be desirable to have at least one Measuring point for this on every floor or in every living unit to provide. This makes sense on every floor because the static pressure and thus the readings of the Inlet pressures have different values. This measuring point can e.g. be installed in the bathroom or in the toilet. If the operator has a manometer permanently connected there even the ability to easily use the heating function to be able to control from his apartment. He can e.g. assess whether the system - after venting - again must be filled up and whether e.g. the desired values for the respective string regulation can be kept.
  • Figure 4 shows the principle History of important pressure values. The following should be noted.
  • the measuring points shown follow an imaginary, vertical one running pipeline with assumed height and fictitious Resistance values.
  • the display does not show the additional resistances resulting from the Distribution networks on the respective floors.
  • the zero point for the double-sided coordinate system is then at rest for the static pressure (p ST ) and for the minimum pressure (p M ) at 0 1 .
  • the intersection of the straight line Zu with the X-axis (P-values) indicates the pressure measured directly behind the pump in the inlet, which is referred to as inlet pressure in the further course of the system.
