Definitions

  • the present invention relates to a method for adjusting a flow temperature setpoint of a heating curve of a heating system during operation of the heating system
  • the required heating energy requirement of a building is not constant, but essentially depends on the prevailing outside temperature.
  • the flow temperature of a heating system is usually determined based on the outside temperature, such as from the document DE 10 2008 040 436 A9 known.
  • a so-called heating curve is used to assign an appropriate outdoor temperature to a corresponding flow temperature. Since the outside temperature is subject to constant fluctuations, the value of the outside temperature used for the heating curve is usually averaged over a period of, for example, 24 hours.
  • the setting of the heating curve is usually done in the initial commissioning by the heating contractor. Often, the heating curve is set too steeply in terms of customer satisfaction in order to prevent customer complaints due to low room temperatures. However, a too steep set heating curve has the consequence that during operation of the heating system, the heat transfer medium is heated to flow temperatures that are higher than actually required, along with a significant reduction in efficiency and energy efficiency. This is particularly problematic when a heat pump is used as the heat generator, which has a constant or substantially constant power output.
  • the pulse width modulated control signal is output by a control device, which for one or more rooms to be heated outputs pulse width modulated signal specific to the particular room.

  • an actuator can be provided for each control valve, which is set up, the pulse width modulated control signal e.g. receive from the room temperature controller and to open and close the control valve alternately according to the pulse width modulated control signal.
  • the heating system further comprises a heat generator for heating the heat transfer medium.
  • a heat generator for heating the heat transfer medium.
