Definitions

  • the invention relates to a flow distributor for heating or cooling systems with connecting parts which are designed to control and/or regulate the flow in at least two heating and cooling circuits branching off from the flow distributor, the connecting parts being connected to actuators by electrical connecting elements, by means of which valves in a flow or return distributor bar or pipe of the flow distributor can be adjusted, and wherein the connecting parts with temperature sensors detect the temperatures of the medium flowing through the flow distributor via temperature measuring points on pipe sockets of the flow distributor bar and / or the return distributor bar, the connecting parts having a power supply component for supplying electricity from a power grid as well as with external devices or modules for recording and/or transmitting system-related signals, at least from temperature sensors or charging pumps of heating boilers or cooling units, even over longer distances via cable or wirelessly are connectable or connected via communication technology.
  • Flow distributors of this type are known in the art.
  • Such a flow distributor serves to feed the fluid medium, in particular water or similar liquids, from a heating or cooling source into a system via a flow pipe and to collect the returning medium via return pipes and return it to the source.
  • the flow of the flow distributor has a corresponding flow pipe and a corresponding return pipe. These pipes are commonly referred to as flow manifolds and return manifolds.
  • a number of pipes branch off from these distributors parallel to each other and are arranged according to the number of heating circuits or cooling circuits to be supplied. The installation is often carried out on a building wall or the like, so that the pipes leading to the individual heating or cooling circuits are aligned parallel to the wall plane.
  • control valves are arranged near the branch to the flow distributor bar or preferably at the branch of the pipes to the return distributor bar, by means of which the flow rate can be adjusted.
  • These valves are coupled with corresponding actuators, i.e. electrical drive elements, with which each individual valve can be adjusted according to its intended purpose.
  • the actuators are coupled to a power supply and are also in active connection or communication with temperature sensors, by means of which the Temperatures of the medium flowing through at the pipe socket of the flow distributor bar and/or the return distributor bar can be recorded and can be evaluated to control the valves.
  • connection parts are provided which are equipped with a power supply component for supplying electricity from a power network as well as external devices or modules for recording and/or transmitting system-related signals, at least from temperature sensors or charging points of boilers or cooling units, even over larger distances via cable or wirelessly are connected.
  • connection parts for the flow distributors are positioned as separate components, usually in distribution cabinets in which the flow distributor is also installed, spatially above the flow distributor and are connected electrically and in terms of communication to the above-mentioned local components via cables within a distribution cabinet.
  • Connection parts are also used that have a modular structure, so that the size of the connection parts is determined by the number of heating circuits/cooling circuits.
  • Flow distributors are also known in which the modularity includes the flow and return distributor bars themselves and the number of heating circuits/cooling circuits determines the number of these modules, with such a module then forming a combined common module of the flow distributor together with the previously mentioned module.
  • This design solution is intended to improve assembly without the need for cabling between the hydraulic switching device and an electronic connection part, in particular the alignment of actuators when establishing an electrical connection between Actuator and electronic circuit arrangement should be improved.
  • the temperatures are recorded at the return port of the flow distributor of the "Fonterra Smart Control" system from Viega, whereby each connection element equipped with measurement technology is already housed in the sensor unit and the temperature data from all sensors is sent via a measuring cable to a separate controller "base unit " will be transmitted.
  • An additional disadvantage of this flow distribution concept is the separate cabling of each actuator to the base unit.
  • the invention is based on the object of providing a flow distributor with connecting parts, with an electrical and/or communication connection assigned to each heating circuit/cooling circuit of the flow distributor without any cabling effort to the actuators and temperature measuring points Actuators and all temperature measuring points are made possible in just a single assembly step The installation effort for the heating and electrical installer is significantly reduced.

  • the connecting parts are combined into a unit by a connecting strip, which has a plug or a socket for each heating circuit, which can be connected to a socket or a plug of the actuator assigned to the same heating circuit or cooling circuit.
  • the connection strip points to each heating circuit or Cooling circuit-related has a temperature sensor for detecting the return temperature (preferably) or the flow temperature, which is contacted with a temperature measuring point on the pipe connection piece of the flow distributor of the same heating circuit, with the arrangement of the plugs or sockets and the arrangement of the temperature sensors on the connection strip for all heating circuits allows the connection strip to be connected to all actuators at the same time and all temperature sensors to be contacted with the temperature measuring points.
  • connection strip The connector elements to be connected to one another (plug and socket) are provided on the one hand on the flow distributor and on the other hand on the connection strip, so that the connection strip with its temperature sensors aligned to the temperature measuring points of the pipe connection piece is only plugged in the direction of the connection points of the flow distributor formed by the plug and socket and temperature measuring point must be made in order to establish the appropriate connections.

  • the mounting plane or mounting surface of the flow distributor is, for example, a plane or surface that runs parallel to the wall surface or housing surface on which the flow distributor is mounted.
  • first and second electrical connecting elements between the connection strip and the actuators arranged on the flow distributor are designed as plugs and sockets, with either the connection strip or the actuators having plugs or sockets that interlock in the intended assembly position.
