Definitions

  • the following invention relates to a drinking water system with a transfer point from a public drinking water supply network and at least one floor or riser and several in the extension direction of the strand arranged one behind the other and each leading to at least one withdrawal point lines that depart from the strand.
  • the present invention relates in particular to a water system according to the DE-U-93 02 446 and DE-U-8 915 477 out.
  • DE-U-93 02 446 is considered in view of the preamble features of claim 1 as generic.
  • the present invention relates in particular to a drinking water system in a building.
  • floor ducting is understood in particular to mean a horizontally extending pipe which supplies a group or all rooms of a floor, for example a hotel or a hospital, with drinking water.
  • a riser connects different floors of a building with each other and usually extends only in the vertical. From the riser pipe go from lines that usually supply superimposed wet cells of the building with drinking or service water.
  • the present invention may be configured as a cold water system; but also conceivable is the training as a hot water system. The invention primarily wants to specify a corresponding drinking water system without permanent circulation.
  • the present invention is based on the problem to provide a drinking water system, which ensures the most hygienic operation and with which the risk of contamination can be effectively countered. Furthermore, the present invention will provide a method for operating a drinking water system, through which the risk of contamination of the drinking water system can be effectively countered.
  • the present invention provides a water system according to claim 1.
  • the ring lines and their branch or mouth are formed on the strand such that when removing drinking or service water to a consumer connected to the strand by a flow in the strand between the branch and the mouth or the loops of the strand a pressure difference is generated, by which in the consumer assigned and the one or more upstream in the flow direction a loop purge flow is generated.
  • the flow in the drinking water system takes place here solely due to the difference in pressure between the transfer point and the delivery point or the sampling point.
  • the present invention proposes a passive drinking water system that does not require a pump to provide flow in the system.
  • the flow in the system is effected solely by the pressure potential which, due to the overpressure at the transfer point, rests against the pressure at a removal point.
  • the driving force for a flow within the drinking water system according to the independent aspect of the present invention is thereafter only the overpressure in the line system, which is applied to the public network in this.
  • the drinking water system according to the invention is then designed so that a ring line with consumer, which is used for water extraction, upstream ring lines are flowed through because of the pressure difference in the strand with a purge flow.
  • the pressure difference is effected by the flow generated in the strand to the consumer.
  • only the last hotel room in the direction of flow must be assigned an assigned sanitary unit in order to flow through the water in this room through the entire floor space of the assigned hotel floor. In this way, a microbial contamination of all arranged on the strand loops can be effectively reduced.
  • a drinking water system is to be specified, which ensures in a simple manner that a consumer can each tap fresh water at a sampling point.
  • a controllable valve ie a motor-driven valve is provided, which can provide a flow and thus an exchange of spent water with fresh water. It is also about providing, for example, fresh cold water at the sampling points.
  • the present invention wants to specify a drinking water system that is as simple as possible. This should do without a circulation pump or the like. The flow in the drinking water system is accordingly effected solely by the difference between the pressure at the transfer point and the pressure at the removal point.
  • the drinking water tank according to the invention is a passive system in which a circulation pump is missing, which ensures a constant flow.
  • a corresponding circulation pump can be part of the drinking water system in conjunction with a controllable valve.
  • the present invention desirably seeks to prevent the water contained in the system from being purified by circulating and passing through a water treatment, as disclosed in US Pat DE-U-93 02 446 or DE-U-89 15 477 is known.
  • the strand and the ring lines connected to it can be flown through by activating the controllable valve which is located at the end of the corresponding strand in the floor.
  • the ring lines and the branch to the respective ring line or the mouth-from the respective ring line in the strand are dimensioned so that a purge flow in the ring lines in any case then results if, upon removal of water to a consumer, via a these loops fluidically downstream ring line is connected to the strand, respectively, a pressure difference between the branch and the mouth is generated, through which a purge flow is generated in the upstream ring lines.
  • a common consumer is, for example, a hand basin, a toilet, a bath or a shower into consideration.
  • leakage currents e.g. a dripping faucet viewed.
  • the flow at the consumer must be substantial, i. correspond to a normal withdrawal from the consumer.
  • a substantially continuous line extending in one floor is also referred to as a "strand", namely as a floor string. This is done for the sake of clear technical teaching in the present application.
  • a floor string in the sense of the application is referred to in the art as a distribution line.
  • the controllable valve is associated with a consumer which is connected to the ring line provided in the strand region.
  • the strand end region is considered to be the end of the strand to which the last ring line in the direction of flow is connected.
  • the controllable valve may for example comprise an indirectly controllable valve e.g. a toilet flush with cistern. Such valves are usually closed by a float.
  • the dishwasher can e.g. have a controllable trigger, so that after controlled release of the cistern water flows in a conventional manner and the valve by the float, i. indirectly after controlled actuation of the shutter is closed. As this example shows, even with an indirectly controlled valve, a flow through the strand inevitably results.
  • controllable valve is provided at the strand end and connects the strand with a connecting line.
  • the controllable valve By activating the controllable valve provided at the end of the strand, the strand is flowed through and in this case preferably all the ring lines which are connected via the strand are flushed through.
  • one controllable valve can be provided on each strand end. By simultaneous or offset driving the controllable valves, these strands can flow through simultaneously or offset in time, this longer exchanged stagnant water in the strand and the associated loops and replaced by fresh water.

  • each controllable valve can be controlled in different ways to allow a cyclic, possibly alone demand-dependent flushing of or all strands.
  • each controllable valve is time-controlled, for example, by a battery-operated time module which is provided directly on the controllable valve. Such a configuration can dispense with all cabling for central control of the controllable valves.
  • control the controllable valves via a central control unit.
  • the past occupancy, for example, of a hotel in the targeted control of the valves can be considered by the operator, only to such Rinse through strands that are likely to be contaminated due to inadequate use.
  • the exchange of potentially contaminated water from the drinking water system can be done in this preferred embodiment with careful use of water.
  • a flow meter and / or temperature sensor can be provided at the end of each individual strand, by means of which, for example, the actual removal via the last ring line in the direction of flow and / or the water temperature in the state are ascertained. Should this removal be at an insufficient level, the central controller will open the controllable valve associated with that string for purging.
  • Any temperature sensors may vary the cycles of rinses. These temperature sensors can reduce flushing intervals at high temperatures, such as in spa areas or in the summer months. The temperature sensors can determine current measured temperature values in the area of the drinking or service water system and compare them with given values for supercritical temperatures. In very cold temperatures can be omitted by appropriate signals of the temperature sensors flushing for a long time.
