  • a changeover valve is also provided.
  • a variety of connections, receiving spaces for sensors and cable connections are provided, which are to be realized in the smallest possible space manufacturing technology low.
  • Such a unit is for example off EP 1 528 330 B1 known.
  • the plate heat exchanger the design of such units tabular, ie long, narrow and comparatively flat, has near its two narrow sides in each case two ports, each associated with different thermal sides of the plate heat exchanger, the connection being such that the plate heat exchanger in its longitudinal direction is flowed through in opposite directions.
  • the EP 1 528 330 B1 known unit is the heating water through the lower connections (lower pair of ports) to and discharged whereas the hot water via the upper ports (upper pair of ports) and is discharged.
  • the invention has for its object to provide a generic structural unit, which is the aforementioned Disadvantages largely avoids, at least reduced and which is inexpensive to produce and their components are easily accessible in the installed state.
  • the assembly according to the invention for a compact heating system with two heating circuits, one for the domestic water heating and one for the space heating, has a first sub-assembly, which has a centrifugal pump.
  • the assembly is also equipped with a plate heat exchanger, which has a lower pair of ports and an upper pair of ports in the installed position, which are each connected fluid-conductively via the plate heat exchanger.
  • a second subassembly has an electrically controlled changeover valve for selectively guiding a heat carrier flow coming from a primary heat exchanger to the heating circuit for the space heating or to the plate heat exchanger.
  • the two sub-assemblies are mechanically interconnected by the plate heat exchanger and connect at least to the top pair of the plate heat exchanger.
  • the upper connection pair of the plate heat exchanger leads the heating water, whereas the lower connection pair leads the hot water.
  • the above-mentioned and also mentioned hereinafter spatial allocations relate to the installation position of the unit in the heating system from the front, so seen from the operating side.
  • a compact heating system is typically arranged wall-mounted, with all four water connections and the gas connection are supplied from below.
  • the primary heat exchanger over the heating water is heated by means of a gas flame in the upper part of the compact heating system, that is arranged above the unit, the arrangement in installation position inevitably dergestalt that the plate heat exchanger is arranged with its flat side approximately wall-parallel, the wiring to the primary heat exchanger near the right and on the left side of the system and the piping connections for the room heating (supply and return) and for the service water (inflow of cold water and hot water connection) are led downwards.
  • the inventive design of the unit stands out from the prior art already substantially by the fact that the wiring is chosen so that the upper connection pair of the plate heat exchanger leads the heating water, whereas the lower leads the hot water.
  • This is particularly advantageous because it structurally facilitates a connection arrangement in which the down out of the assembly out in a row connections approximately parallel to the wall on which the compact heating system is located, is located.
  • the user-water-carrying connections must not be performed in front of or behind the hot water-carrying connections, but can be derived practically directly down.
  • the wiring to the primary heat exchanger is simplified, which must necessarily be directed upward due to the installation position in the upper arrangement of the primary heat exchanger.
  • the sub-assemblies are mechanically connected via the plate heat exchanger, in such a way that they are advantageous only or substantially only connected via the plate heat exchanger.
  • This arrangement is by design free of stresses that are caused by thermal expansion of the plate heat exchanger.
  • the entire unit can be simple and be formed inexpensively by only two sub-assemblies and the already separately produced plate heat exchanger.
  • the arrangement of the assembly according to the invention enables a central gas guide approximately in the middle of the compact heating system, since in this construction, a corresponding clearance can be formed in this area.
  • an electrically controlled switching valve has proven to have a substantially cylindrical receptacle for at least one, but typically two movable switch body. These switch body sit on a shift rod, which is typically moved by an electric motor.
  • the cylindrical receptacle of the switching valve is arranged so that it is arranged in the installed position in front of the plate heat exchanger and with its longitudinal central axis parallel thereto.
  • Such an arrangement is unusual and offers design, manufacturing and technical advantages.
  • the arrangement is advantageous in that the longitudinal central axis of the receptacle is arranged at a right angle askew to the running axis of the centrifugal pump.
  • the receptacle on an end-side closure over which the one or more of the switching body are accessible and which is accessible in the installed position of the page is such that remains until the side panel of the compact heating system sufficient clearance that allows removal or replacement of the switch body without problems.
  • the switch body is moved by an electric motor
  • the electric motor can be arranged in the installation position on the receptacle for the switch body and directed to the primary heat exchanger connecting piece of the changeover valve in installation position forward.
  • the electric motor is protected by the liquid-carrying components of the assembly.
  • Altnernativ is provided according to the invention to arrange the electric motor in the installed position before receiving the switch body and directed to the primary heat exchanger leading connecting piece of the change-over valve in the installed position upwards.
  • the electric motor in installation position is particularly well accessible from the front, in addition, there is a largely direct wiring to the primary heat exchanger out.
  • a bypass between flow and return is advantageously formed by an arranged in the installed position in front of the plate heat exchanger pipe section, which line interconnects the sub-assemblies accordingly.
  • the pipe section should be possible parallel to the longitudinal center axis of the plate heat exchanger and telescopic, so on the one tolerances of the plate heat exchanger with respect to the distance of the terminals of a terminal pair can be compensated in a simple manner, on the other hand thermal expansions of the typically metallic plate heat exchanger compared to the otherwise typically made of plastic injection molding sub-assemblies can be compensated.
  • the telescoping can be ensured in a simple manner by nested pipe sections with intermediate seal, such as an O-ring.
  • the bypass line is provided with a double bend, wherein a substantially perpendicular to the plate heat exchanger part receives in an installed position from the front preferably between two connecting pieces of the unit accessible and influencing the flow through the bypass actuator mechanism.
  • Such an adjustment mechanism can then be advantageously incorporated from the front and is easily accessible even in the installed position.
  • At least one further connection can be provided in the front pipe section arranged parallel to the heat exchanger, for example for the integration of a sensor.
  • This is particularly favorable, since on the one hand this area is particularly well accessible in the installed position, and on the other hand, it is difficult to implement in terms of tool technology, so that the provision of such a further connection increases the tool costs only insignificantly.
  • the first subassembly has a flow rate regulator, which is advantageously arranged in a common housing with the centrifugal pump.
  • a flow regulator is provided for the service water flowing through the unit and to be heated and typically operates mechanically, but may also be electrically controlled via an electronic control, in the form of a control valve.
  • Such a flow regulator ensures that, regardless of the line pressure, essentially the same amount flows through when the service water extraction valve is fully opened. This ensures in particular that at too high line pressure the Hot water in the plate heat exchanger can still be heated to the desired temperature, ie that whenever possible water can be removed at the same temperature.
  • the flow regulator arranged in a common housing with the centrifugal pump.
  • Such a housing may be constructed in one or more parts, in a multi-part design there is the advantage that the same unit can be created either with or without flow regulator, without making major structural changes.
  • first sub-assembly side by side arranged pipe sections which are interconnected by a component having at least parts of the flow regulator, in which the flow is deflected by about 180 °.
  • a component having at least parts of the flow regulator, in which the flow is deflected by about 180 °.
  • Such a component can be easily replaced by a 180 ° elbow manifold for a simplified design without a regulator, without having to change the construction and thus the injection molding tool or the injection molding tools for the first sub-assembly.
  • the line sections are advantageously connected in such a way that one of the line sections adjoins the heat exchanger and the other line section preferably adjoins or forms a lower connection of the building unit in the installed position.
  • the non-adjoining the heat exchanger line section advantageously has a flow meter.
  • a flow meter operating according to the vortex principle is incorporated here, wherein the line section is designed so that a sufficient distance for calming the flow and after the obstruction a sufficient measuring section is formed before the obstruction which triggers the oscillation of the flow the flow rate-dependent vibration can form and can be detected by a pressure sensor or differential pressure sensor.
  • the flow meter to arrange near the beginning of the line section seen in the direction of flow, ie in the direction of flow with sufficient distance in front of the flow regulator.
  • the aforementioned line sections are arranged side by side, in such a way that they are arranged in the installed position approximately perpendicular and side by side in front of the plate heat exchanger next to the centrifugal pump.
  • Such parallel line sections are particularly favorable in terms of production since they can be produced with simple drawing cores. The same applies to the connections to be provided perpendicular to the line sections, be it to the plate heat exchanger or to accommodate the flow meter.
  • the line section leading from the flow regulator to the plate heat exchanger has an opening which is conductively connected to the suction side of the pump.
  • the connection thus formed with the suction side of the pump can then serve for the integration of a shut-off valve, via which the heating system can be filled without having to provide a separate line connection for this purpose.
  • the sub-assembly may also be formed without opening, which is possible by slight change of the tool, in which case advantageously a shut-off valve and a connecting piece is provided on this sub-assembly and on the other sub-assembly also with a connecting piece Shut-off valve, but for service water.
