Definitions

  • the present invention relates to a device for a heating system with a low loss header Decoupling of a primary heating circuit from secondary heating circuits and with a heating circuit distributor for the secondary circuits.
  • the heating circuit distributor is often preceded by a low loss header.
  • the hydraulic switch separates the primary circuit of the boiler from the secondary circuits and ensures that all secondary circuits each the required amount of heating water at a constant temperature is fed.
  • the temperature in the secondary circuits is true lower than the temperature of the heating water at the boiler flow, but this is at modern low-temperature heating systems not disadvantageous.
  • Heating circuit distributor and hydraulic separator separate components, each for the same or two manufactured by various manufacturers and manufactured by Heating installers can be installed. In doing so at the location of the heating system the heating circuit distributor and the hydraulic switch for itself on a wall or a Carrier arrangement attached and then together as well as with the other parts of the heating system suitable non-flexible or flexible pipe elements connected. This completes the installation and subsequent Attaching a legally required Thermal insulation is obviously complex and corresponding expensive.
  • the problem is solved according to the invention in that the device made of hydraulic switch and heating circuit distributor with switch housing and distributor housing and all between the two flow connections as a prefabricated integrated unit is executed and only one flow connector on the switch side and a return pipe to connect with at least one heat generator provided in the primary circuit and only two or more each on the distributor side Flow connections and return connections for connection with heat consumers provided in the secondary circuit having.
  • the integrated design advantageously leads to the fact that Considerable number of line connections to be made on site is reduced. This also increases the risk of Errors and the resulting leaks during manufacture the corresponding line connections are reduced, because it is usually automated in prefabrication and therefore work with high quality can be worked manually during an on-site installation must be, often with limited space are present, the work, especially welding or soldering work.
  • the attachment the integrated unit easier because now only nor the one unit on a wall or a support device has to be attached, whereas earlier two separate components had to be kept for themselves.
  • Another The advantage is that a certain one is already in advance low loss header with a specific heating circuit distributor assembled into the integrated unit can be, the two parts thermally are optimally coordinated.
  • a first development of the device according to the invention provides that the switch housing is aligned vertically is that the heating circuit distributor is a combined Flow and return manifolds with a single horizontal aligned, inside the flow and return areas is divided housing and that the two housing perpendicular to each other immediately and / or firmly with each other via at least one rigid piece of pipe connected, preferably welded.
  • the single ones Parts of the facility remain in this configuration their usual and local installer known arrangement and orientation, so that on the The installer does not need to make any changes here is, but continues to work in the usual way can be.
  • An alternative embodiment of the device according to the invention provides that the switch housing is aligned vertically is that the heating circuit distributor is a combined Flow and return manifolds with a single vertical aligned, inside the flow and return areas is divided housing and that the two housing adjacent to each other running parallel to each other directly connected to each other, preferably are welded.
  • the switch housing is aligned vertically is that the heating circuit distributor is a combined Flow and return manifolds with a single vertical aligned, inside the flow and return areas is divided housing and that the two housing adjacent to each other running parallel to each other directly connected to each other, preferably are welded.
  • Another contribution to achieving low manufacturing costs in manufacturing the facility is that at least the flow connection from the hydraulic Switch to the flow area of the heating circuit distributor by simply breaking through an area in which the two housings are in direct contact with each other, is formed.
  • the flow connector on a higher level opens into the switch housing than the flow connection between the hydraulic switch and the flow area of the heating circuit distributor and that above the mouth of the flow connector in the switch housing a gas plenum with a vent and / or valve is provided.
  • the device can be used at the same time take over the function of an air separator, whereby a corresponding component in the heating system no longer has to be provided separately.
  • the heating water flow rate is relatively low and therefore the flow is absolute Laminar, effective ventilation or degassing guaranteed. Functional impairments of the Heating system by air or in the heating water This avoids gas bubbles.
  • Heating water free of air or gas bubbles is particularly important with modern ones Heating systems with condensing boiler and electronically regulated circulation pump important.
  • Heat exchangers in condensing boilers have to achieve high efficiency usually very many flow paths, each with a very small one Flow cross-section, in which an air bubble to do so can lead to one or more flow paths not more of the heating water will flow, causing harm local overheating of the heat exchanger up to can cause a burn.
  • electronically controlled Circulation pumps are sensitive, especially with a shortened lifespan, on air or steam bubbles in the pumped heating water.
  • the return nozzle on at a higher level opens into the switch housing than the flow connection between the return area the heating circuit distributor and the low loss header and that below the mouth of the return pipe in the switch housing a mud collecting room with a Blowdown connector and / or valve is provided.
  • Flow rate of the heating water is low and the flow is laminar, can occur in the return water Dirt and dirt carried along from the heating circuits Mud in the deepest part of the hydraulic switch deposit and collect the forming sludge collection chamber without that there is a risk that the mud will pass from here Whirling gets back into the water cycle.
  • the dirt-sensitive circulation pump is raised Wear caused by dirt carried in the heating water and mud are protected and there are condensing boilers Blockages in the narrow flow paths mentioned above in the Avoided heat exchangers.
  • This property can also the device according to the invention in many cases a separate water filter inside the heating system be saved. Draining the accumulated Sludge can easily become regular Maintenance of the heating system, e.g. by briefly opening one that serves as a drain valve Ball valve.
  • the flow cross section the switch housing is four to ten times as large as the flow cross section of the flow connector and the Return pipe.
  • the switch housing and the distributor housing with measured in the horizontal direction of the same depth are. It also creates a harmonious visual impression the establishment achieved.
