Definitions

  • Units of this type are increasingly used in compact heating systems today, especially installed in gas heaters or heating units.
  • they usually include other components, such as air separators, safety valves, Changeover valve and the like.
  • They are as a unit, i.e. H. as Installation and assembly unit designed so that a simple and Space-saving arrangement guaranteed within the heating system is.
  • such a unit is easy to install and maintain, because accessibility is only possible at a few central points the otherwise narrow installation space must be guaranteed and otherwise in the event of a repair, the unit is completely replaced and in the factory or otherwise overhauled by a specialist and reused can be supplied.
  • Such a unit is known for example from EP 0 460 399 A2.
  • This known unit is intended for a gas boiler, which contains two heating circuits, one for water heating and one for space heating, both by one common gas-heated primary heat exchanger supplied with heat will.
  • This known unit is for assembly in the lead of the Primary heat exchanger is provided and accordingly instructs one this lead connecting suction nozzle and two discharge nozzle connected to the two heating circuits.
  • this unit has an air separator attached to a backflow chamber is connected through which the return lines of the Heating circuits are guided through the unit.
  • this known unit a flap between the Pump outlet and the two pressure ports provided in Depending on the direction of rotation of the impeller controlled automatically is.
  • An essential constructive feature of the invention is that in addition to the air separator also a dirt separator is provided, which is circulated within a flow Deposits are removed from the circuit and thus for operational safety of the entire system, and also contributes an air separator is arranged in a common housing, which is arranged according to location. And this must be the dirt separator and the housing having the air separator essentially be arranged vertically so that the air is up and the Dirt can escape downwards.
  • a vertical arrangement in a common housing is also special cheap, since the main lines in this area, for example a gas boiler, run in the same direction, which means only a little Installation space is required.
  • Installation position is a free space at the top for attaching a quick breather and below it can be used, the dirt collection container too keep accessible in the installation position.
  • the inventive design is constructive Unit also for inclusion in the return provided, resulting in lower thermal stress on the Components leads and moreover less susceptible to cavitation Is noise.
  • a particularly compact unit is formed in that the Switching element in the area between dirt separator and air separator is arranged, expediently according to the present invention not both heating circuits through dirt and air separators be led, but expediently only for the heating circuit provided by the dirt separator and both heating circuits or one of these heating circuits through the air separator. Because both heating circuits at least in the area of the primary heat exchanger air separation is sufficient and dirt in just one cycle. It is useful to Dirt separator in the return of the heating circuit for space heating to arrange, since experience has shown that this is the most common Dirt accumulates. To prevent this dirt from entering the Area of the switching element or the pump, the Dirt separator is suitably arranged in front of it. Accordingly becomes the suction nozzle leading to the heating circuit for space heating Advantageously connect to the dirt separator on the side.
  • the switching element in the area between dirt and air separator is arranged, then it is appropriate to use the second suction port, which leads to the heating circuit for water heating, in Area of this switching element to be connected.
  • the arrangement ensures that the backflow from both heating circuits Water is still fed to the air separator before it reached the pump set.
  • An air separation of both circuits can be useful, although it is generally sufficient to have one Circuit, namely to vent the heating circuit for space heating.
  • the additional ventilation of the heating circuit for hot water preparation through the air separator is therefore particularly of Advantage because the ventilation is independent of the operation of the room heating is guaranteed. Such a constellation results, for example in summer when the room heating is switched off and the system is only used for water heating.
  • the lateral arrangement of the suction nozzle on the dirt separator and the air separator housing is therefore so advantageous because the connections are easily accessible is.
  • the unit usually mounted so that the free end of the engine after points in front, while the actual pump and the one behind it Components arranged between the mounting wall and the engine are. This area is narrow and difficult to access.
  • the dirt separator is expediently used as a cyclone separator formed, with a removable vessel on the underside of the Housing should be provided in which the dirt collects and that can be emptied.
  • the heating system shown in Fig. 1 consists essentially of a gas-heated primary heat exchanger 1, a secondary heat exchanger 2 for water heating and a secondary heat exchanger 3 for space heating (radiators).
  • the secondary heat exchangers 2, 3 form essential components of heating circuits that are brought together in the area of the primary heat exchanger 1 and can be controlled and circulated via a unit 4.
  • the function of such a heating system is known per se. in the pure space heating operation becomes liquid in the primary heat exchanger 1 (boiler) heated, for example, by burning gas.
  • the Liquid reaches radiators through a pipe system the space heating, which is shown in Fig. 1 as a secondary heat exchanger 3 are.
  • the cooled back from the radiators In assembly 4 water first gets into a dirt separator 8, then into an air separator 9 and finally through the Pump 6 back into the primary heat exchanger 1 for heating.
  • the Secondary heat exchanger 2 for water heating is included out of function, which is the return line leading to the unit 4 through the switching flap 10, which is spring-loaded in this position is cordoned off.
  • the structural design of the unit 4 results in particular from the representations according to FIGS. 2 to 4.
  • the electric motor has as is usual with pump units of this type, essentially one cylindrical housing with terminal box 13 on the side in which the electrical connection cable is clamped.
  • the centrifugal pump 6 is attached to the electric motor.
  • the Centrifugal pump has an approximately tangentially arranged pressure nozzle 14 on and on the side facing away from the motor 5 a coaxial suction mouth arranged to the impeller axis.
  • the suction connection of the Pump housing is elongated and opens approximately tangentially in the there is a cylindrical air separator 9.
  • This channel 24 connects an inner tube 25 of the under the chamber 18th Dirt separator 8 arranged axially to the air separator 9 with the chamber 18.
  • the dirt separator 8 has an essentially cylindrical outer housing similar to that of the air separator 9 on, which is open towards the bottom and can be screwed on cup-shaped container 25 is lockable.
  • the Dirt separator 8 is designed as a cyclone separator, accordingly there is an inlet opening approximately tangential in the cylindrical side wall provided, which is designed as a suction port 26 of the assembly 4 is and for the connection of those coming from the secondary heat exchanger 3 Return line is provided.
  • auxiliary nozzle 27 Connects to the chamber 18 laterally (on the left in FIG. 4) an auxiliary nozzle 27 in which a not shown in detail Pressure relief valve 28 is screwed in, its outlet into the open opens or can be removed via a hose.
  • FIGS. 5 to 9 differs from the above essentially in that the cable routing within the unit is different and so that the unit is designed differently.
  • the unit is marked there with 31.
  • the one with the above Design of functionally matching components are identified in the same way and therefore will not be repeated in detail described.
  • the embodiments described above have, except for the lid, Containers and other moving parts in one piece, made of injection molding Manufactured housing on, which is inexpensive especially in large series are to be manufactured and enable a very compact construction.
