Definitions

  • the invention relates to a structural unit for a compact heating system.
  • Such units are state of the art and are used if possible to take all the fittings of such a heating system in a tight space and provide the necessary channel connections and line connections. This is not only a compact design to be achieved, but beyond both the manufacturing and assembly costs and the subsequent maintenance costs are reduced.
  • a unit for a compact heating system which has two heating circuits, one for heating the heating water for the central heating and another for heating the service water.
  • the structural unit described therein is comparatively compact and essentially composed of three injection-molded parts, of which the first centrally arranged forms the pump housing, which is designed to be open at the front for receiving the motor assembly, and form the two other fitting housings adjoining on both sides.
  • the present invention has the object to further improve such a unit, in particular to increase the functionality and thus simplify installation and maintenance on.
  • the invention provides a unit for a compact heating system, which has rear connections for a plate heat exchanger, a central pump housing or pump housing component, connect to the valve body on both sides, wherein the pump housing for receiving the impeller and for connecting the electric motor is designed to be open at the front.
  • a front accessible plug-in space is provided, which serves to accommodate at least one valve.
  • these insertion spaces each form a connection base for a connecting piece of the heating system, a channel leading to the plate heat exchanger and at least one further channel or connection.
  • the basic idea of the present invention is to form a connection base for the lines to be connected or connected by the two laterally adjoining the pump housing fitting housing with their insertion spaces and at the same time to receive the necessary fittings, by means of the front accessible plug-in spaces, so that a change of fittings even when installed easily possible.
  • the plate heat exchanger connects the side fitting housing, so that the pump housing can be incorporated form-fitting between this fitting housing.
  • Such a structural unit can, as will be described in detail below, preferably be formed from three injection-molded parts which can be produced exclusively by means of drawing cores, that is to say without melting cores, which is advantageous in terms of production technology.
  • Armature according to the present invention are not only valves or other switching elements, this may also be components such as air or dirt separators or parts thereof or, for example, a closure cap for a control opening.
  • the insertion spaces are arranged relative to the paired connection pieces for the plate heat exchanger so that they overlap one connection in the insertion direction, so that no separate transverse channel is required for the connection between the insertion space and connection piece of the plate heat exchanger.
  • the insertion spaces are each connected to the bottom side with a channel leading to the plate heat exchanger channel through an opening in the ground, wherein this channel extends in the direction of insertion and to the connecting piece of the heat exchanger.
  • insertion space and channel can each be formed by coming from the front or from the rear of the drawing cores in the tool, wherein the pulling core for the channel is also used for the connection piece.
  • both fitting housing have a downwardly directed channel to a connecting piece for the heating flow or the heating return, which adjoins the insertion space.
  • the insertion spaces each have a circular cross-section and are arranged with their longitudinal axes substantially parallel to the axis of rotation of the centrifugal wheel. Then the fittings / inserts to be incorporated into the drawer spaces can also be used from the front when mounted. Due to the round cross-section, a simple seal, for example with O-rings, is possible. In addition, bayonet or screw can be realized, which make it necessary to rotate a valve in the insertion space.
  • One of the insertion spaces is advantageously provided for receiving a switching valve, in particular a 3/2-way valve, which is preferably inserted as a plug-in module from the front into the insertion space.
  • the insertion unit expediently not only the valve body, but also the sealing seats, so that in the case of a defect or during maintenance, all the essential parts of the switching valve forward together with the plug-in unit can be pulled out and overhauled or replaced.
  • the insertion space in the region of the switching valve has corresponding channel connections for the three channels to be alternately connected in pairs.
  • the switching valve controls the heating water flow coming from the primary heat exchanger either in the heating network or in a secondary heat exchanger, typically a plate heat exchanger.
  • the control takes place in dependence of the hot water flow, for which appropriate sensors and control electronics are provided.
  • the valve is actuated by appropriate actuating means, preferably by electric motor.
  • valve body transverse to the insertion direction for the changeover valve a further, preferably accessible from above insertion space provided for the integration of the control means, in particular the electric motor is provided.
  • the valve-near arrangement of the motor at the top is particularly favorable in terms of mechanical power transmission and has the advantage that the motor can be pulled up out of the insertion space in order to maintain or replace it, for example. Since there is typically a certain amount of free space above the unit, this positioning is therefore particularly favorable and easily accessible, ie. H. Both valve and motor can be replaced without having to remove the assembly.
  • This channel which is then controlled by the changeover valve, leads down to a connecting piece for the heating flow.
  • This connection piece for connection to the stationary lines on the underside of the unit is particularly favorable, since the lines are routinely routinely installed in the floor or baseboard area, especially when retrofitting the heating system, as is common in old buildings and therefore come from below. The connection of these lines is therefore simplified, in particular because of the good accessibility of the line connections in this area of the compact heating system.
  • bypass channel connects, which preferably extends parallel to the insertion direction under the valve-side insertion space to the rear and there opens into a leading to the suction side of the pump transverse channel.
  • bypass channel does not short-circuit the pump hydraulically, it is regularly necessary to use a control valve.
  • This is advantageously used from the back of the channel and set by the expert in the installation of the system.
  • this arrangement is favorable because the valve can be incorporated into the drawing core opening required anyway for the channel.
  • this arrangement also offers considerable advantages, in particular during operation of the system. It not only increases the compactness of the unit, but also ensures that in the installed state, the control valve is not accessible, so not accidentally manipulated by an operator can be, but only targeted by the professional installation or removal of the unit.
  • a channel with line connection for leading to the primary heat exchanger line connects, preferably transversely to the insertion direction and on the side facing away from the pump side of the Armaturengehöuses. This coming from the primary heat exchanger line is connected by the switching valve either with the input line to the secondary heat exchanger (plate heat exchanger) or the heating flow.
  • the primary heat exchanger is typically located in the upper area of the compact heating system, ie above the unit and its lines lead laterally down to the unit, it is also particularly advantageous montagetechnisch to provide this connection seen from the front on the left side of the valve-side fitting housing, since then namely a connection of the conduit usually formed from a substantially rigid tube is easy to accomplish.
  • each of the fitting housing a frontally accessible insertion space is provided, it is expedient to complete the insertion spaces by bayonet connections by means of a lid or the insertable fitting therein, so that an exchange of valves or the Access to the drawer spaces is quick and easy.
  • identical bayonets are preferably used for both insertion spaces, so that identical seals and the same cover or fitting connections can be used.
  • the other insertion space is provided and designed to receive a dirt separator. Then, after opening the lid of the insertion space of the dirt and so that the dirt collected therein are removed or is at least accessible to remove any deposits therein. It also needs no separate installation space for a dirt separator can be provided.
  • the insertion space is dimensioned correspondingly large in order to ensure a sufficient effective flow cross-section despite the Abscheider füren flow cross-section reduction.
  • the dirt separator is therefore advantageously incorporated as a sieve-like insert in the insertion space, which is removable from the front after removing a lid. In the lid of the insertion space further fittings or sensors can be incorporated.
  • a safety valve is incorporated in the cover, which releases a connection to the outside atmosphere when a predetermined pressure is exceeded, or a channel connection into a drain or a collecting vessel.

If, on the other hand, the assembly is to be used without heat storage, then only the lateral connections are to be closed. By then not incorporated dividing wall, the plug-in housing is freely continuous in the axial direction. This design variant thus allows the same tool to produce a unit both for compact heating systems with as well as for those without heat storage.
  • the poor Schmutzabscheider simplyen fitting housing vertically downwardly directed channel to the Anchlussstutzen for the heating return.
  • a connection for integrating a sensor is provided on the insertion space provided for the dirt separator, preferably on the upper side.

  • Einschubraums as a connection base further increased also can be formed on a comparatively short way the required connection channel to the suction nozzle of the pump, which is located immediately adjacent to the dirt separator side valve body. Since both the valve body and the pump housing or this receiving injection molding component are manufactured as separate injection molded parts, which are joined only during assembly, these transverse channels can also be advantageously realized by drawing cores in the injection mold, without costly melting cores are required.
  • the unit is designed so that not only for the heating flow and the heating return downwardly directed connection piece are provided on the underside of the unit, but also the two other connections for the hot water supply and coming from the compact heating system heated hot water are provided on the bottom.
