Definitions
- the invention relates to a method and a device for supplying water and air to a swimming pool arranged in a closed building or room or provided with a roll cover, into which the air and water are blown in below the water surface.
- EP 0 219 730 B1 proposes a device for supplying water and air, in which the water is conveyed by means of a pump driven by an air-cooled motor and the cooling air is conveyed to the swimming pool by means of a collecting device and a discharge device connected to it or is fed to a mixing station located upstream in the direction of flow.
- An air delivery device coupled to the motor of the water pump for example an impeller, a screw conveyor or a blade fan wheel, which is taken up from the surroundings of the installation site of the pump, is used to draw in this air.
- the engine cooling air is to be used as service air, with the intention of making use of the heating of the cooling air by the engine for the purpose of heating the swimming pool water.
- the air extracted from the interior of the building or the closed room in which the swimming pool is located is used, as has been known for a long time in whirlpools, to "bubble up the water".
- fresh air from swimming pool ventilation can also be used to prevent the smell of chlorine, which is unpleasant due to the chlorination of water, from spreading in the immediate vicinity of the water, which is normally unavoidable as air contaminated by trihalogens because of the necessary water disinfection. Further developments of the method according to the invention are described in the subclaims.
- the sucked-in air can either be blown into the swimming pool separately from the water supply and the water injection or can be fed to the swimming pool as an air / water mixture with filtered water or with fresh water via one or more inflow nozzles.
- separate or coupled piping systems are required, and a mixing device in a corresponding manner when supplying a water-air mixture.
- Water is preferably taken continuously or discontinuously from the swimming pool, filtered and fresh air drawn in from the outside is added in a metered amount to the filtered water.
- the fresh air supplied via the water from the outside and released into the room creates a slight overpressure above the water surface, which avoids steam formation when there are temperature differences between warm water and cooler air above the water surface.
- an overpressure-sensitive valve which is let into a wall of the swimming pool hall or the other closed room can be used for pressure compensation.
- the fresh air supply and the air removal are preferably controlled or regulated via the pressure relief valve mentioned in such a way that the air in the closed space above the swimming pool is completely exchanged every three to eight hours, preferably every six hours.
- the pressure relief valve therefore has two functions: on the one hand, an excessively high room air pressure above the pool water is avoided, and on the other hand, the air is cleaned of the undesirable trihalogens.
- the stated object is achieved by the device according to claim 6, which according to the invention is characterized by at least one air supply line, via which air can be drawn in outside the building or the enclosed space (as fresh air) and which opens directly or indirectly into the swimming pool below the water surface , into which the sucked-in air can be blown in separately from the water supply or together with the water supply via appropriate inflow nozzles.
- the swimming pool preferably has at least one water drain, through which water is removed and fed to a filter via a piping system and from there to the swimming pool again via the inflow nozzles, the air drawn in from the outside being able to be blown into a pipe of the piping system, which is between the filter and the inflow nozzles is arranged.
- This piping system ensures that the water removed from the swimming pool is first filtered and only then mixed in the desired water / air mixing ratio by controlled metering.
- the swimming pool has one or more water outlets which are designed as a floor outlet, overflow, skimmer or the like; the water removed from the swimming pool is supplied to a reusable valve via corresponding supply lines, the branches leading to the filter and for direct return in the swimming pool or to a mixing device with sucked air.
- the described reusable valve can thus optionally be switched so that the water removed from the swimming pool is either first filtered or, if filtering is not required, is returned directly to the swimming pool.
- the mixing device for injecting fresh air is equipped with a non-return valve which closes automatically if the air pressure in the air supply line is too low or too low.
- the sucked-in air can preferably be blown in via a plurality of inflow nozzles arranged in the floor and in the swimming pool walls, possibly also separately from the water inflow nozzles, so that a uniform supply of fresh air is achieved over the entire water volume of the swimming pool.
- the closed room in which the swimming pool is located i.e. the swimming pool in public baths, has a pressure relief valve embedded in a wall with an air duct leading to the outside.
- This pressure relief valve can either be adjustable, depending on the hall air pressure, or it can be designed as a simple swivel flap or controlled fan.
- FIG. 1 An embodiment of the invention is shown in the drawing, which shows a schematic section of a room having a swimming pool.
- the relevant room 1 has a ceiling 10, outer walls 11, 12 and a floor 13 and a swimming pool 2 with a floor 20 and one or more side walls 21.
- the floor has an outlet 22 and an inflow nozzle 23; corresponding inflow nozzles 24 and 25 are let into the side wall 21.
- a water overflow 26 with a skimmer 27 is arranged above the water surface 40.
- the floor drain 22 and the water overflow 26 are connected to corresponding water drain lines 28, 29 which open into a common supply line 30, which via a reusable valve 3 with a filter 4 and a water supply line 5, which flow into corresponding branch lines 51 and 52 to the Inlet nozzles 23, 24 and 25 branched.
- a further air supply line 6 which sucks in fresh air from the outside, possibly via an air filter 7 and a pump (not shown in more detail), via which the fresh air is fed into line 5 via an injection nozzle 8, from where it is present as a water / air mixture the inflow nozzles 23, 24, and 25 is supplied.
- the respective water and air flow is indicated by arrows.
- the fresh air flows through the nozzles 23, 24 and 25 into the swimming pool water, rises and is distributed in the space 9 above the water surface 40.
- a pressure relief valve 14, which is shown here simply as a swivel flap, ensures that the gas pressure in the Regulate room 9.
- the pump for the air supply and the pressure relief valve and possibly the injection nozzle 8 can be connected to one another via a control device in such a way that fresh air is supplied and discharged in a metered manner in order to achieve ideal water-air mixture ratios and decontamination of the air contaminated by trihalogens in the Effect room 9.
- the floor level outside of the swimming pool 2, which is not shown in the drawing, is arranged approximately at the level of the upper edge of the swimming pool, so that the entire piping system shown next to the swimming pool 2, including the filter, is covered thereby or a corresponding space is formed below the floor which is accessible for filter and line maintenance work.
- Variants of the illustrated embodiment are possible in such a way that the air supply line 6 opens directly to inflow nozzles of the swimming pool, which are separated from the water supply nozzles.
- the present device according to the invention can also be retrofitted to existing swimming pools, which only have a pipeline system connected to a filter, by in addition to the air supply line 6, a corresponding pump device (fan wheel or the like), a T-connection is inserted at the location of the injection nozzle 8.
- a corresponding pump device fan wheel or the like
- the device known from EP 0 219 730 B1 can also be modified such that the air which is supplied to the ventilation devices is sucked in via corresponding air supply ducts which have a connection to the outside air, that is to say which leads to the outside.
- the procedure with the device shown can be designed, for example, that with an assumed room volume of 240 m 3, 6 40 m 3 per hour are conveyed via the supply line 6, so that a complete air exchange is achieved in about 6 hours.
