Definitions

  • Heating systems with liquid circulation are full of air before they are filled.
  • the air is compressed and rises to the topmost parts of the piping system which are located, where the air is removed through venting screws in the radiators.
  • the air removal performed during the filling of the piping system is an operation requiring a great deal of work.
  • This invention comprises a method and an apparatus, with the aid of which it is possible to completely abandon venting made at the radiators.
  • the essential factor in the invention is that, during the filling of the piping system, one uses a flow rate which is so high that air bubbles travel in the flow downwards in the field of gravity in the vertical heating pipes, whereby the air in the piping system can be removed from the piping at the filling point.
  • the rise velocity of a bubble in water is proportional to the square root of the diameter of the bubble.
  • the resistance coefficient of a spherical body is required for the calculation. According to information in literature it is about 0.5, the Reynolds number being between 1,000 and 200,000. If the diameter of the bubble is 5 mm, then a calculation with the resistance coefficient of 0.5 gives 0.36 m/s as the rise velocity of the bubble. In the example cases the Reynolds number is 2200, as calculated by viscosity values corresponding to a water temperature of 30 °C.
  • a considerably large liquid flow must be supplied to the piping system and removed from the system in order to remove the air bubbles from the piping system. This is not possible e.g. through the taps used normally for filling and emptying. Substantially larger flow orifices are required.
  • the required large liquid flow can be supplied and removed with the aid of connecting elements according to the invention without making any extra changes in the piping. It is also possible to use the large flow supplied to the piping system and removed from it for a mechanical cleaning of the piping system.
  • Figure 1 shows a principle with the aid of which the method and components according to the invention can be utilised.
  • the liquid is supplied into the piping system through a supply opening 1 therein, so that the radiators are filled from the return side, and the air in the piping system is carried through the radiator valves into the input pipes of the heat piping system.
  • the liquid flow rate is sufficiently high, then the air bubbles are carried with the liquid in the vertical return pipes downwards and further out from the piping system via a discharge opening 2.
  • the piping section between the supply opening 1 and the discharge opening 2 is hydraulically shut off.
  • Figure 2 shows a typical heat piping pump in cross section.
  • the motor of the pump is fastened by a bolt joint to the pump housing 4.
  • the bolt joint When the bolt joint is opened the impeller fastened to the motor axis and the motor will come off as one unit. Only the pump housing 4 is left in the piping system.
  • a connecting element 3 is fastened to the pump housing 4 according to figure 3. This creates the required supply opening 1 and discharge opening 2.
  • the seal 5 between the connecting element 3 and the pump housing 4 shuts off the hydraulic connection between the supply opening 1 and the discharge opening 2.
  • German patent publication 197 09 700 presents an equipment which is primarily intended for the cleaning of heat exchangers, where the connecting parts enabling supply of the cleaning liquid are fastened between the heat exchanger and the flanges of the piping, both on the input and discharge sides.
  • the connecting parts have a flow barrier, so that the heat exchanger is disconnected from the piping system in the flow sense.
  • An application according to the invention utilises a single connecting element, which is connected to the housing of the centrifugal pump or instead of the pump of the piping system being the object of the actions.
  • the liquid is circulated through the whole heating system.
