Definitions

  • the invention relates to a device for aspirating liquid in ventilation systems with a suction pump, at least one suction pump connected to the suction for sucking the liquid and detection means, which are set up to turn on the suction pump as a result of detection of the liquid.
  • the invention further relates to a ventilation system with such a device.
  • Such a device and such a ventilation system are from the EP 0 552 913 A2 known.
  • the device disclosed therein is set up for the automatic removal of condensate from a cooler condensate pan of the ventilation and air conditioning system, which has no drainage option due to gravity via a drain pipe.
  • the condensed water is sucked by means of a suction pump via a suction point at a point from the condensate pan.
  • the control of the suction pump is carried out by detection means which monitor the liquid level in thedeerkondensatwanne. When the liquid exceeds a predetermined level, the detection means generates a trigger signal for starting the suction pump.
  • Ventilation systems which are also referred to as ventilation systems, air conditioning or the like, with devices for the extraction of water, for example, in the DE 197 10 398 C2 , of the JP-A-09033091 A or the DE 3903665 A1 disclosed.
  • Object of the present invention is therefore to provide a device of the type mentioned, with which it is possible in a simple and cost-effective manner to achieve a complete extraction of surface residual puddles occurring areally.
  • each suction part is a suction head, which is connected to the suction pump by means of a suction hose and has a flat underside, which is designed such that a gap for guiding the liquid is provided between the surface to be suctioned off and the underside of the suction head can be formed to the detection means and the suction tube.
  • This gap can be arbitrarily shaped be, z. B. extensively extended or single or multiple groove-shaped.
  • the term "gap" is summarized.
  • liquids distributed in a planar manner on solid surfaces can be substantially completely sucked off.
  • one or more suction heads are used, which can be flexibly placed in existing facilities due to a hose connection.
  • each suction head on a flat bottom, which generates a gap as described above. If the Absaugkmü rest on the surface to be sucked, the liquid is displaced from the flush-mounted areas in the gap and performed without pumping effect by a convenient shaping of the gap to the detection means. This bundling of the residual water leads to reliable triggering of the pump by the detection means, even with very small amounts of water.
  • the liquid is sucked off the surface to be sucked off.
  • the term flat underside is to be understood in the sense of the invention that the underside of the suction head when resting on the surface to be sucked covers an area which is greater than, for example, over four times as large as, the cross-sectional area of the suction tube connected to the suction head is.
  • the device according to the invention can be used in any room ventilation systems.
  • the ventilation system in those areas where water may be incurred, a drain on the larger amounts of water can flow due to the gravity of the water.
  • a drain on the larger amounts of water can flow due to the gravity of the water.
  • Such a sequence is arranged for example laterally or on the underside of a condensate tray of the ventilation system.
  • a capillary effect can be generated by the gap.
  • the gap is dimensioned so that it produces a capillary effect.
  • a capillary-effective intermediate space is formed through the gap. Residual water is therefore accelerated due to the surface tension of the water in the gap and sucked towards the detection means.
  • an arbitrarily shaped gap can be delimited between the underside of the suction head and the surface to be suctioned off, which has a gap width of 0.01 mm to 4 mm in any spatial direction.
  • the capillary effect enhances the concentration of residual water, especially in the case of suction heads with groove-shaped gaps.
  • the design of the underside of the suction head according to the invention in principle arbitrary, as long as a gap is created by the support of the suction and thus ensures a leadership of the liquid to the detection means and the suction hose.
  • the underside may be formed, for example, as a continuous surface, are formed on the raised areas. As soon as the suction head rests on the surface to be suctioned, a gap thus forms, the gap width of which depends on the increase in the raised areas relative to the remaining boundary surface of the underside of the suction head.
  • indentations are made in the flat underside.
  • the indentations can have any shape as such.
  • the indentations are furrows or channels. With the help of the channels or furrows an even stronger bundling and management of the residual water amounts to the detection means is possible.
  • the detection means are arranged on the suction heads.
  • the detection means are arranged on the Absaugköpfen or in other words in the range of Absaugkmü the sensitivity of the detection increases considerably, so that even the smallest amounts of residual water can be effectively recognized and sucked.
  • the detection means are arranged on the underside of the suction head and project at least partially into the gap, wherein a venting channel is provided. Due to the direct arrangement on the underside, the detection means limit the gap with their liquid-sensitive sensor areas, whereby the accuracy of the detection is increased. In this case, the venting channel ensures that the air that is displaced by the water transported to the detection means, can slide past the sensor. This is particularly important in the generation or utilization of a capillary effect of importance.
  • the suction heads are designed so that the flow rate of liquid at each suction head is limited so that in each suction sufficient suction is ensured, so that at least at a suction liquid is sucked. This is particularly important when several suction heads are used and air is sucked in at one or more suction heads, the suction power of the suction pump is then no longer sufficient to still suck liquid on the or the remaining suction heads.
  • control valves arranged between the suction heads and the suction pump and a control unit for regulating the control valves are provided, wherein the control unit is connected to the detection means.
  • the control unit receives, for example, at regular intervals measurement signals from the Detection means.
  • the control unit is equipped with a control logic, for example in the form of suitable software.
  • the control logic compares the received measurement signals with predetermined on / off scenarios and, in the presence of such a switching scenario, switches a suction process through the suction pump on or off.
  • control unit opens the control valves in succession, whereby only one control valve is always open.
  • suction power of the pump is always present at each suction head and, on the other hand, a sufficiently high flow resistance is provided even when suction pumps with low pumping speeds are used, in particular even when the pumping power is due to the intake of air would not be sufficient on one or more Absaugköpfen to entrain also the amounts of residual water at one or more other Absaugköpfen / suck.
  • the suction heads for fixing in the ventilation system have magnets and / or weights. By the magnets and weights a simple fixation of the suction heads is possible.
  • the suction heads are made of an elastic, adapting to the shape of a surface material. Due to the elastic configuration, the device according to the invention can also be used, for example, on spherically shaped, for example, uneven or curved surfaces of condensate trays.
  • the Absaugkée to prevent microbial growth of an antimicrobial or made of microbially inert material supports the device according to the invention in that the biological contamination of ventilation systems is avoided not only by the removal of residual water puddles, but also by the antimicrobial material of the suction head.
  • At least one solids filter is connected in front of the suction pump. Due to the solid filter, the suction of small solid particles in the suction pump is avoided.
  • At least one water separator is expediently connected in front of the suction pump.
  • the water separator helps prevent damage to the non-dry-running suction pump. Water drawn in by the suction pump is effectively removed by the water separator.
  • the suction hoses are connected via a provided with a disinfection control valve inlet hose with a container which is filled with a disinfecting liquid, wherein a control unit is provided for opening and closing the disinfection control valve.
  • the control unit triggers the disinfection via the disinfection control valve, for example at fixed intervals.
  • suction hoses are connected via a provided with a ventilation control valve ventilation hose with the outlet of an aerator, wherein a control unit is provided for opening and closing the ventilation control valve and for controlling the aerator.
  • the control unit can trigger the ventilation via the disinfection control valve at fixed intervals.
  • the aerator has a heating device.
  • air residual water is more effectively removed and dried the suction and / or the air conditioning system itself in its interior. This inhibits the multiplication of microorganisms.
  • the suction heads are connected to each other via connecting arms, so that a network structure is formed.
  • the Absaugköpfe and the connecting arms may also be integrally formed.

  • the suction hoses are vacuum-resistant.
  • the ventilation system which is equipped with the device according to the invention, on a surface to be vacuumed, which is covered with an insulating protective film.
  • the protective film avoids any possible corrosion of the pasted surface.
  • the thickness of the film is basically arbitrary. Advantages in terms of unhindered and complete suction of the water or the cost, however, arise when the protective film is as thin as possible.
  • the insulating protective film has markings for arranging the suction heads. It is by no means necessary to cover the entire surface with a protective film. By marking the protective film whose finding is facilitated in the often difficult to access areas of the ventilation system.
