Definitions

  • heat generators such as heat pumps, biomass boilers, gas boilers, gas boilers, oil boilers, district heating stations, etc. have been continuously developed in order to increase the efficiency of heat generation and heat transfer. What the various heat generators have in common is that they each have particularly efficient operating modes or operating modes and less efficient operating modes or operating modes.
  • the efficiency of the heat generator can be optimized for higher flow temperatures, for example between 50°C and 120°C, or for lower flow temperatures, in particular between 30°C and 50°C.
  • heat generation is particularly inefficient and wear and tear is particularly high when the operating times and/or pause times of the heat generator are relatively short. These short operating times and/or pause times are also referred to as clocking or stuttering operation. Consequently, it is desirable that clocking or stuttering is avoided as much as possible.
  • a heat generator can be a heat pump, a gas boiler, a gas boiler, a biomass boiler, an oil boiler, a district heating transfer station, etc. (heat generator types).
  • the method includes the steps of detecting a valve position of a valve that is set up to control a volume flow of a fluid from the heat generator to a radiator, and controlling the heat generator as a function of the detected valve position.
  • a fluid can be a gas or a liquid.
  • Sensing a valve position may include sensing a control signal that controls the valve and/or sensing a position of the valve by a sensor.
  • a radiator can be, for example, wall heating, floor heating, a radiator, a convector, a mixture of the types of radiators just mentioned, etc.
  • the valve can be part of a (room) thermostat, in particular an electronically controllable (room) thermostat.
  • the valve can be a thermostatic valve.
  • the generation of heat can be matched to a heat removal by a radiator in a particularly simple manner.
  • short, inefficient operating intervals of the heat generator due to heat being generated but not consumed can be avoided, and the heat output of the heat generator can be optimized and reduced. This leads to less wear and tear on a heating system and lower energy consumption.
  • the heat generator can be controlled in such a way that when a valve is closed or only slightly open, in particular when all valves are closed and/or only slightly open, the heat generator is not operated in a heat-generating mode, in particular not even then when there is a heat demand.
  • a particularly advantageous embodiment can also include the step of determining, depending on the detected valve position of a plurality of valves, at least one, in particular one or more, from the group: a reference valve position, a minimum valve position, an average valve position and/or a maximum Include valve position, the control of the heat generator depending on the reference valve position, the minimum valve position, the average valve position and / or the maximum valve position can be done.
  • the heat generator can be switched off when one or more valves are closed or the valve position (valve opening) of one or more valves is below a predetermined limit value.
  • the heat generator can be switched off when the minimum valve position falls below a first valve limit value, the maximum valve position falls below a second valve limit value, the average valve position falls below a third valve limit value and/or the reference valve position falls below a fourth valve limit value.
  • the designation of the valve limit values as the first, second, third and fourth valve limit value only serves to differentiate, has no numerical meaning and also has no ordering effect.
  • a reference valve position, a minimum valve position, an average valve position and/or a maximum valve position can be determined as a function of a weighting of the valve position of the plurality of valves.

  • a distinction with regard to the heat transfer surfaces can include a distinction with regard to the surface area, the external geometry, the surface structure, a material, etc.
