Definitions

  • the invention relates to a pump with in or on the pump housing integrated power control, depending on the temperature of the fluid to be maintained by the pump Differential pressure is set.
  • the electronics change the differential pressure setpoint to be observed by the pump Dependence of the measured media temperature. With increasing Temperature the setpoint is raised, i.e. speed and delivery rate increase with decreasing temperature the setpoint is reduced, i.e. speed and flow rate decrease.
  • the object of the invention is to provide a type of control for a electronically controlled pump to find the optimal one Use for condensing technology enables the requirement after the lowest possible return temperature is fulfilled.
  • This pump is also available in one system can be used for cold control.
  • this object is achieved by a pump with the Features of the characterizing part of claim 1 solved. Further configurations according to the invention result from the characteristics of the subclaims.
  • Pump wildly the otherwise necessary communication between the boiler and pump are no longer required for condensing technology.
  • the pump also no longer has to be integrated directly into the burner become. This makes complex data lines and / or radio links avoided.
  • the energy benefit is in condensing technology and / or the higher with a cold regulation, the lower the return temperature.
  • the most possible lower return temperature is achieved by a pump with a ⁇ p-T control with negative controller action from the pump self-regulated because the temperature increases the Pump speed is reduced. The result is that the Flow rate drops and with it the return temperature. When the return temperature drops, the speed the pump, however, increased. The result is that the output increases, and with it the amount of heat given off to the system.
  • the temperature sensor required to measure the media temperature can either be directly in the pump or in its vicinity be mounted or integrated. Will the information about the media temperature outside the pump and the Pump control supplied, this can be done via a radio link and done over a data line. It is also conceivable the data signals by means of light, in particular infrared light, transferred to. It goes without saying that the Control context can be specified or programmed as required is so that the pump meets the respective requirements of the pipe system and adaptable to the components connected to it is.
  • the pump with special functions, such as. Switching off, break times or the like, reacts. If the pump according to the invention in a heating system installed, it can thereby reduce the night Detect heating system independently and from energy-saving technology Reduce the pump output automatically for reasons.
