Definitions

  • the invention relates to a structural unit for a compact heating system with the features specified in the preamble of claim 1.
  • Such units are state of the art (EP 1 528 330 B1 ) and are used to accommodate the numerous housed in such a compact heating system components and assemblies and to handle together with the assembly as a whole.
  • the heat transfer medium for space heating which is usually formed by water is heated in a typically above the unit in the heating system arranged primary heat exchanger and from there into the installed inside the house secondary heat exchanger in the form of radiators
  • the domestic water is heated via a Heat exchanger, which forms part of the assembly and which is typically formed as a plate heat exchanger.
  • the line coming from the primary heat exchanger is usually separated from the space heater and connected to the plate heat exchanger by means of a priority circuit in the removal of hot water.
  • the heat transfer medium then flows through the plate heat exchanger in one direction, whereby the process water is passed in the opposite direction.
  • part of the unit forming circulating pump is provided for the flow through the heat transfer medium. Since the connection to the space heating is disconnected via a valve in the case of hot water extraction, quasi-stationary states result within the then remaining circuit, so that for a given pump output the heat transfer medium is always passed through the heat exchanger at a constant speed.
  • the service water which is performed on the other side of the heat exchanger in countercurrent, is subject to fluctuations, be it the pressure fluctuations in the water supply network or the fluctuations that occur in that at the sampling point, the nozzle is only partially opened.
  • a flow meter is arranged in the unit in a service water, which always ensures by means of a corresponding control that a minimum amount of hot water flows through the heat exchanger, otherwise diverted the heat transfer or the heating of the primary heat exchanger is turned off.
  • Out EP 1 884 720 A1 includes a generic unit to the prior art, in which for controlling the amount of hot water flowing through the unit is provided in its flow cross section variable throttle body for controlling the temperature of the service water.
  • This throttle is integrated in a part of the unit, their construction is technically complex.
  • the invention has the object, a generic unit structurally simpler form.
  • the assembly according to the invention for a compact heating system with two hot circles, one for the domestic water heating and one for space heating, has a heat exchanger for domestic water heating, one side of which a heating circuit and the other side of the hot water can be flowed through.
  • a heat exchanger for domestic water heating one side of which a heating circuit and the other side of the hot water can be flowed through.
  • an externally adjustable flow regulator is provided in the unit in the flow direction.
  • the invention is provided to provide two side by side, preferably vertically arranged line sections in this sub-assembly or possibly also as a separate component, which are connected by a component receiving at least parts of the flow rate regulator, in which the flow is deflected by about 180 ° ,
  • This construction of the line sections lying parallel next to each other is particularly favorable in terms of tools, since the cores necessary for the production of the line sections can be formed as drawing cores which are to be pulled in the same direction.
  • These line sections are connected by a component that deflects the flow by 180 °, which absorbs a majority of the parts of the flow rate regulator.
  • the flow regulator is typically designed so that in the component an externally operable control member for adjusting the flow rate is arranged. It can therefore be set after installation of the unit and commissioning of the compact heating system in a simple manner by the expert on site, the flow rate, which ultimately determines the temperature of the hot discharged service water.
  • the basic idea of the present invention is therefore to provide an externally adjustable flow regulator in the assembly in order to control the flow rate of the process water, i. ensure largely independent of external influences that always a constant amount flows through the heat exchanger, so that at least when the bleed valve is fully open, always tap water is removed at a substantially constant temperature, once apart from the temperature fluctuations of the cold process water, which do not remain without influence on the temperature of the warm service water.
  • the flow regulator in the assembly essentially makes it possible to compensate for pressure fluctuations in the supply network in their effect on the hot water temperature and to enable an independent hot water supply in a structurally simple manner.
  • flow rate regulators with predefined flow rates are state of the art, they are of little use for the stated purpose since they can not be adapted to the local conditions.
  • the gas supply pressure is too low, it may be necessary to regulate the flow rate to a relatively small value to ensure that the process water exits the system at a minimum temperature.
  • the solution according to the invention makes this possible by means of an externally adjustable flow rate regulator, wherein from the outside in the sense of the present invention means that the adjustment can take place in the installed state, typically after opening the front panel of the system.
  • the setting can be done in a simple mechanical form, for example by means of a knurled screw or in electronic form, for example by means of a knob or slide control.
  • the flow regulator is arranged in the flow direction of the process water upstream of the heat exchanger.
  • a plate heat exchanger is used as a heat exchanger, as is quite common in compact heating systems of this type.
  • a sub-assembly which according to the invention advantageously comprises a centrifugal pump and the flow regulator, preferably with at least a portion of the flow rate regulator in a common housing.
  • the arrangement of the flow regulator in the centrifugal pump having sub-assembly is structurally simple and convenient, because then in the other sub-assembly typically a change-over valve is provided which limits the constructive open spaces on that side significantly.
  • the entire mechanism of the flow rate regulator is expediently integrated in the component which deflects the flow through 180 °, whereas the elastic diaphragm cooperating with this mechanism is incorporated in the area of the housing division or of the adjoining component and advantageously provided in the form of an elastic O-ring can.
  • the arrangement in the region of a housing division is therefore of particular advantage, because it is free of undercuts and thus easy to implement in terms of tools.
  • the elastic element can be easily replaced without having to disassemble the component itself.
  • the latter line section can be made comparatively long in this arrangement, which enables the arrangement of a vortex flow meter which can be produced cost-effectively, a high measuring accuracy and has long term stability.
  • the reassurance required for this purpose can be realized in the non-adjoining the heat exchanger line section by appropriate length training.
  • Such a flow meter which operates according to the vortex principle is then advantageously arranged in the direction of flow near the end of the other line section, ie at a considerable distance from the flow regulator in order to ensure a sufficiently long calming section.
  • the juxtaposed line sections are arranged approximately vertically in front of the plate heat exchanger and next to the centrifugal pump in the installed position.
  • the line connection of a line section can be realized in a structurally simple way to plate heat exchanger, wherein the adjacent terminal of the plate heat exchanger can be directly connected to the suction side of the pump line.
  • Such an arrangement allows on the one hand the opposite flow around the plate heat exchanger and on the other hand, the arrangement of the circulation pump in the return to the primary heat exchanger, which is particularly favorable in terms of temperature level.
  • the subassembly has at least one subsequent to the plate heat exchanger arcuate channel.
  • both subsequent to the plate heat exchanger channels of this sub-assembly are arcuate, so that they can be realized from one side of the tool with swivel cores.
  • Such pivot cores enable the lateral offset of the lines to each other without causing a further pulling level of the cores.
  • one of the arcuate channels to the suction side the pump and the other arcuate channel are connected to the vertical line section leading to the flow regulator.
  • the leading from the flow regulator to the plate heat exchanger line section on an opening which is conductively connected to the suction side of the pump allows the space-saving and favorable arrangement of a filling device for the heating circuit, in which an interposed valve is opened to direct hot water into the heating circuit when needed, either at start-up or in later operation when liquid is to be replaced. Since such an arrangement is not permitted in all countries, the component can also be formed without an opening by slight variation of the corresponding core, then a line connection is provided, so that the valve can serve as a conventional filling valve for the heating circuit, depending on country-specific regulations.
  • a similar connection with shut-off valve is then provided on the other part of the housing unit on the other side of the plate heat exchanger, so that can be done by attaching a connecting line, the filling of the heating circuit.
  • a connecting line the filling of the heating circuit.
  • it can be provided between these terminals and a Disconnecteur, ie a fixed line section with therein provided check valve.
  • the opening in the vertical line section leading to the flow rate regulator is particularly advantageously designed such that it opens into a valve chamber which is open at the bottom in the installation position and which is provided or designed to receive a valve body or a shut-off body.
  • a downwardly open valve chamber is technically particularly favorable to implement, since the sub-assembly typically anyway downwardly open lines for connection to the fixed lines must have and therefore in any case pulling cores must be provided in this direction in the tool.
  • the assembly 1 shown in the figures is arranged in the installed position in a chassis 2, which accommodates all components of the compact heating system and is attached to its rear wall 3 typically hanging on a wall or can be fixed floor-mounted or ceiling-mounted in providing a corresponding frame.
  • the assembly 1 is arranged in the lower part of the chassis 2 and has four downgoing outgoing lines 4, 5, 6 and 7, which lie in a row parallel to the rear wall of the chassis 2 and to which the house-side water-carrying lines are connected.

  • the flowing back from the return of the space heating water passes through the right in the installed position line connection in the line 7 and thus in the first sub-assembly 13, which includes, inter alia, a centrifugal pump 15 and an air separator 16.
  • the line 7 opens into the suction chamber of the centrifugal pump 15, to which the air separator 16 connects at the top.
  • the discharge nozzle of the pump 15 is connected to the leading to the primary heat exchanger line 8.
  • the pump housing and the remaining lines of the first sub-assembly 13 are formed by an injection-molded component.
  • the centrifugal pump 15 has, as usual in such units, a flanged, in the installed position accessible from the front electric motor 17, the terminal box 18 is disposed at the top of the motor housing.
  • the line section 19 includes a flow diverting by 180 ° component 22, which connects the line section 19 with the right in the installed position next to it between pump 15 and line section 19 arranged right line section 20.
  • the component 22 comprises a flow regulator, with which the flow rate is controlled, so that it is substantially independent of the line pressure.
  • a pin-shaped actuating body 23 in the component 22 is arranged in alignment with the line section 20.
  • the adjusting body has at its upper end a tool holder, here a square, with which it can be rotated about its longitudinal axis.

  • the hot water line can be connected to the heating circuit to fill the heating circuit or refill.
  • the sub-assembly 13 may be formed by correspondingly changing the take-up 45 and the channel 44 forming die core of the tool so that an opening between the channel 44 and the line section 42 is not formed.
