The invention relates to drinking or service water system piping, which has a connection to the municipal water supply, and at least one feed riser or lift the riser at least one branches off from him storey pipeline and/or at least one branches off in the direction of the water flow from the lifting strut and/or floor pipe o-ring pipe, and at least one is connected to the lifting strut and/or storey pipeline and/or in the circular pipeline to the consumer, and return riser, in which the feed end of the riser and/or lifting the riser and/or floor pipe and/or the circular pipeline.

In particular, the invention relates to a system that is served cold drinking or process water. As in the system for the hot drinking water and process water, and in the system with cold water can cause the growth of bacteria, such as Pseudomonas aeruginosa (referred to in subsequent Pseudomonas) or Legionelle, when the water temperature is favorable for their growth range between 9°C and 42°C. In this regard, reference is made to the source Mikrobiologisch-hygienische Aspekte des Vorkommens von Pseudomonas aeruginosa im Trinkwasser” (Microbiological and hygienic aspects of occurrence found in drinking water), Energie/Wasse-Praxis 3, 2009.

In the systems described, for example, in EP 1845207 A1, which are made in the form of an annular systems, it is necessary to ensure the perfect quality of drinking water, as well as to prevent heating of cold water to unacceptably high temperatures to regularly clean installation. Due to this greatly increases water consumption and related operating costs. If you consider drinking water as a food product, the water must be kept at temperatures below 9°C. In this respect, reference is made to the above source.

Just at the height of summer can be a considerable excess of this temperature, the supply of fresh water. In this regard, reference is made to the source Legionellenvermehrung in Kaltwasserleitungen” (Multiplication of Legionella in cooling water pipes), Arbeitskreistrinkwasserinstallation und Hygiene, RAS 06/2010. Accordingly, even after prolonged washing of pipes eliminates the risk of bacteria.

From EP 1845207 A1 an appropriate system in which when initiating flushing simultaneously washed all circular pipelines. When this valve is used, which enables the uniform washing of all closed circular pipelines. Rinsing is carried out with a uniform time intervals, it is not important whether there is or h is t in the annular piping high temperature water. This means that every time the washing is complete, but the uncontrolled change of water throughout the installation.

Proceeding from this prior art, the basis of the invention is the creation of a system of potable or process water, with which to prevent high water consumption and related operating costs ensures compliance in the system water hygiene requirements, i.e. not having unacceptably high concentrations of bacteria, particularly Pseudomonas.

To solve this problem, according to the invention, it is proposed that the pipeline system consists of a feed riser or lift riser and return riser closed recirculation pipeline and that the circulation pipeline integrated device for flowing cooling water, which allows cooling or cooled potable or process water to a predetermined temperature.

Due to this implementation is achieved that are in the pipeline system, water is mainly targeted can circulate in the respective pipes, the temperature flowing in the system water is lowered to a predetermined temperature, i.e. preferably below 9°C, which results in suppressing the growth of bacteria, particularly Pseudomonas. If this is m no need for increased water flow since water can circulate in the system and only purposefully allocated to consumers. This circulating water is directed through a cooling device, for example, a cooling unit, which cools the water to hygienically preferred temperature, preferably below 9°C. Instead of directly passing through the cooling unit, the cooling water can be made with the help of drive cold water, which is supplied with a cooling unit.

If necessary, it can be provided that the connection to the mains water supply is carried out between the output of the cooling device and the applying or lifting strut.

In this solution, shoditsa that the supply network to supply water to a low enough temperature. In this case, the connection to the mains water supply may be included between the output of the cooling device and the applying or lifting strut.

In particular in summer, i.e. at high ambient temperatures, is not always ensured that the water from the water supply network has a sufficiently low temperature.

On this basis, preferably provided that the connection to the mains water supply is included in the flow direction before entering the cooling unit in the circular pipeline.

When this supply of fresh water happens is from the water supply prior to cooling with a cooling unit, or storage of cold water. Thus, also at high ambient temperatures, as, for example, at the height of summer, supplied from the water supply fresh water cooled to hygienically preferred temperature.

To achieve a uniform flow through the piping system required hydraulic alignment with each other separate pipelines. This can be done using the static control valves pipelines, but with the disadvantage that the long-term water abstraction in some parts of the install leaked enough water to other parts of the installation can not be sure.

To achieve in this case, however, sufficient flow through all parts of the unit and hydraulic control depending on the temperature, with the aim of holding the temperature of the cold water preferably 9°C, it is proposed that one or each annular pipe with at least one user included adjustable regulating valve of the pipeline, which, depending on set temperature lying above the setpoint temperature flowing in the annular water pipeline opens a stream to the maximum value, and at lower temperature limits the flow to the minimum value, while the control valve of drobopro the Yes preferably included within a circular pipe in the flow direction after the last user or integrated into the connecting valve between the circular pipe and the main pipe system pipes.

Also to achieve the targeted circulation is proposed to combine a circular pipe with an adjustable regulating valve of the pipeline, which is at a temperature below the temperature valve provides only a residual volume of flow through the valve. When exceeding the temperature valve is detected by a temperature sensor valve and the valve is opened, so that the circular pipeline is fully proteced. Upon reaching the target temperature, i.e, for example, 9°C, flow through the valve is again limited to a residual volume of flow, since the temperature sensor valve sets the valve in the position in which through the valve flows only residual volume flow.

This residual volume flow is necessary to ensure a constant flow temperature sensor in the valve and thereby the continuous measurement of the actual temperature in the corresponding ring or pipeline. Due to the temperature-dependent opening of the valve at full transmission, full flow passes through separate areas for so long, until it reaches the target temperature, respectively, only when exceeded the target temperature.

For the same reason, according to the invention provides that at least the least one or each storey pipeline with at least one user included adjustable regulating valve of the pipeline, which, depending on set temperature lying above the setpoint temperature flowing through the water pipeline opens a stream to the maximum value, and at lower temperature limits the flow to the minimum value, while the control valve of the pipeline is preferably included in the story the pipeline in the direction of the flow of water after the last user or integrated into the connecting valve between storey pipe and the main pipe piping system.

Also for the same reason, the invention provides that at least one of the lifting strut of at least one user included adjustable regulating valve of the pipeline, which, depending on set temperature lying above the setpoint temperature flowing through the riser water opens the flow to the maximum value, and at lower temperature limits the flow to the minimum value, while the control valve of the pipeline preferably included after the last in the flow direction of the consumer.

Thus, in particular, provided that the management of the regulating valve of the pipeline is carried out using a probe or measuring the temperature of the Executive what about the element, which is located in the flow path of water through the control valve of the pipeline.

During normal operation, not all adjustable regulating valves pipe open at the same time, so that the total pressure of the circulating system is available for the passage of flow through the respective area, and thus the corresponding plot can happen quick change water.

Additionally, it can preferably be provided that the connection to the municipal water supply system and piping system filter is installed to filter bacteria.

Through such a filter system is sent coming from the network of drinking water fresh water and, possibly, existing bacteria, such as, for example, found or Legionella, are filtered out of the water.

To ensure sufficient circulation in the system is additionally provided that the circulation system has a circulation pump.

By performing according to the invention are achieved significant benefits. For example, prevents invalid heated flowing in the drinking water system, where such drinking water pipelines laid in parallel pipelines supply channels and mines, and the supply pipelines have a higher temperature or pass through them flows and environments which have a higher temperature.

Drinking water from a water network, when it has too high temperature can be cooled in the system to a temperature that prevents the growth of Pseudomonas, or other bacterial species, thus preferably connected to the input of fresh water is in front of the entrance to the cooling unit.

Using installed on the inlet side of the system filter system can reliably filter found and Legionella. In connection with the installation of the circulation of cold water you can set the temperature of the drinking water so that reliable are the official requirements, for example, hospitals or other

In addition, the subject invention is controlled depending on the temperature of the valve, in particular, circulating valve, in particular, the control valve of the pipeline, for use in cold drinking water or in cold process water, preferably drinking or industrial water according to any one of claims 1 to 9 claims.

If you follow the rule that drinking water should be treated as a food product, it is necessary to ensure the presence of the temperature of drinking water in the pipes is always hygienically favorable temperature range below 9°C, with the aim of PR is to prevent contamination by bacteria. To ensure this, you must drinking water, as it is known from hot water systems, regular change in pipelines that can be done by circulation or flushing the system.

From EP 2098647 known fittings for connecting the annular piping with the lifting struts or story pipelines, which should provide a reliable washing circular pipeline. When applying this coupling ring pipelines are washed in washing or circulation, regardless of whether there is or is not in the pipeline fever drinking water. Rinsing is carried out on the basis of different resistances to flow in a circular pipe and connecting fittings. This results when washing to unnecessary large water discharge into the sewer. Another disadvantage is that the flush water from the existing circular pipeline is mixed with fresh water and subsequent passes through circular pipes, which prevents the rapid and complete change of water. Since the inlet risers and/or circular pipelines, as a rule, are of different length, the adverse risers and/or circular pipelines are washed badly.

From DE 10056715 A1 and DE 102005038699 B4 known controlled depending on temperature valves for use in systems of the x hot water, above the set temperature of the water provide residual volume flow, and decreasing the temperature below the set temperature will increase the volumetric flow through the valve, with the purpose of filing in the appropriate riser or the corresponding annular water pipeline with sufficient temperature.

Proceeding from the prior art, the basis of the invention is the creation of controlled depending on the temperature of the valve, in particular, controlled by a temperature sensor movement, which can be used in cold water systems and which sets the volume flow in the circulation or flushing the system with cold water so that the cold drinking water or process water flows at a particular temperature through the pipeline.

To solve this task according to the invention it is proposed that the valve, depending on preferably installed or invariably set temperature higher than this temperature temperature flowing through the valve environment opens the flow to the maximum flow rate, while being at a lower temperature or at the temperature flowing through the valve environment closes the stream to a residual volume of flow.

A simple solution consists in the fact that in the corresponding valve condition is yavlyaetsya constant temperature, which should happen in the process of switching valve.

However, preferably be set in the valve the desired temperature. Using a controlled depending on the temperature of the valve, in particular, using a controlled temperature sensor move the valve, you can set the volume flow of the flowing medium so that drinking water or process water with installed valve temperature flows through the respective conduits. In particular, it provides that are used in systems of cold water or cold service water valve below the predetermined or set temperature environment, for example, 9°C, passes only the residual volume flow, which is used for temperature control valve, as above set temperature, i.e. when an invalid higher temperatures, increases the volumetric flow, to ensure flushing and removal of inadmissible heated water. When this regulation can be carried out thermally by means of staying in a high volume flow of thermocouple, for example, with costacabana with temperature sensor movement, or with the help of an adjusting element, which is controlled by means of controlled depending on the temperature of the external energy.

Predpochtite the flax also provides the ability to control the level of residual volumetric flow, which bypasses the valve lower temperature, for example, 9°C. this makes it possible for each individual pipeline to coordinate required for each pipeline the cooling energy.

However, preferably provided that the valve has a defining thread of the adjusting element, the ability to control or installation in which both extreme positions is provided by measuring the temperature of the flowing medium element directly or through connected therewith the drive.

In particular, it is preferably provided that the actuating element is located in the flowing environment thermocouple with extension element for follower type.

In one preferred embodiment provides that the valve has a housing with an inlet and outlet for flowing environment.

In another preferred embodiment provides that the valve provided in the connecting the valve with which the annular conduit connected to the main supply pipeline.

Additionally preferably provided that the valve is built into branches off from the main supply pipe o-ring pipe and the valve is connected (docked) to the adjusting element so that when opened to the maximum flow rate for which the Apana main supply pipe is closed so that that the volume flow of the main supply pipe passes through a circular pipe, however, achievement of a given (nominal) temperature valve again reduces duct to a residual volume of flow, and the main supply pipe is opened again.

Provided to control the valve adjusting unit may be located in a separate building or in connecting the valve with which the circular pipe is connected with the main supply pipe. The adjusting unit may also be made so that upon exceeding a predetermined temperature integrated thermocouple with the temperature sensor move opens up a greater flow and simultaneously closes the main pipeline system, so that the volume flow of the main pipe flows through a circular pipe, which is controlled depending on the temperature of the valve. When the set temperature is reached, the flow is again reduced by using controlled depending on the temperature of the valve to a residual volume of flow, and the main pipeline system is released.

Figure 1 shows a circulation system cold water, according to the invention. While fresh water is supplied from the public supply of drinking water through p is clucene 1 and is directed through the filter 2, which filters fresh water available to bacteria, such as, for example, found or Legionella. Through 14 connection fresh water is directed into the circulation system in the selection processes of the water. In the circulation system, the description of which will be described below, the circulation is supported by means of the circulation pump 13. Circulating in the circulation circuit, the water is directed through the cooling device, which cools the water, preferably to a temperature below 9°C, and thus provides the system hygienically preferred temperature. Chilled water is directed into the system in the direction of the arrows and through the lifting strut 12 is distributed to the individual story 4 pipelines. To a single storey pipes 4 are connected via the 8 outputs and inputs 9 ring piping 5. The path of flow in circular pipes 5 specified by the adjacent arrows. In this direction of flow in circular pipes 5 are provided consumers 6, such as, for example, showers, taps or the like, and an adjustable regulating valve 7 of the pipeline. Regulating valve of the pipeline is included in the annular pipe 5 after the last customer 6. It can also be integrated into the connecting valve, which is located in the entrance area 9.

Adjustable regulating valve 7 of the pipeline can be installed (configured) on a given (nominal) temperature above which an adjustable regulating valve 7 pipeline opens, for example, using a temperature sensor, and when lowering the temperature below the set temperature regulating valve 7 of the pipeline is closed until the residual flow. This residual flow in an adjustable regulating valve 7 of the pipeline is constantly washed by the temperature sensor, it can measure the actual temperature of the water in the annular pipe 5. This preferably between exit 8 and the input 9 of the ring pipeline storey pipe 4 has a throttle 10, for example, static control valve with the function of the throttle, with the aim of creating a hydraulic balance between the circular pipe 5 and storied line 4 and thereby provide residual flow in an adjustable regulating valve 7 of the pipeline.

If the temperature in one of the annular piping 5 rises above the set in the corresponding regulating valve 7 pipeline values, then pass through the regulating valve of the pipeline is fully open, and the resistance in the pipe system falls significantly below the resistance customizable others is scale 10. This leads to the fact that the total circulation flow is directed through the annular pipe 5, while in the annular pipe 5 again set the desired water temperature, so that the control valve 7 of the pipeline is installed in a position with a minimum transmittance. Thus, it is achieved that the stream flows only through the annular pipe 5, which exceeded the maximum specified temperature, with a maximum volume flow rate, so that there is a rapid change of fresh water.

Figure 1 right shows the return riser 11.

In figure 2, 2A shows another embodiment of a circulation system of cold water according to the invention. In this case, fresh water from the municipal water supply is introduced through connection 1 in the circulation system in the direction of the stream before cooling device 3 through the inlet 15 so that supplied fresh water immediately cooled, which is particularly preferable when the fresh water, for example, in summer, the temperature may be elevated. The circulation of cold water again is provided with a circulation pump 13. Through the lifting strut 12 are supplied with several storey pipes 4 which are connected to the corresponding many consumers 6. On each lying in the direction of flow after the connected consumers 6 the end of the story 4 pipelines located the Yong adjustable regulating valve 7, 7.1 pipeline. As already indicated with reference to figure 1, this adjustable regulating valve 7, 7.1 pipeline below the set temperature has a residual volume flow to determine the actual water temperature in the corresponding storey pipeline 4 with sensor temperature regulating valve 7, 7.1. If the temperature falls below the set temperature, the adjustable regulating valve 7, 7.1 pipeline is opened and through the corresponding storey pipe 4 flows maximum coolant flow. Thus, it is possible to quickly and purposeful change of water in the corresponding story line. Through the return riser 11, which serves as the collector of the riser, water is directed from the story of pipelines 4 again in the cooling unit 3.

When this check valve 16 at the bottom in the return line and check valve 16 in the inlet fresh water pipeline (1) prevents in the absence of water abstraction reverse buoyancy of the water circulating through the circulation pump 13 in the municipal water supply network. Additionally, the check valve 16 between the point 15 of the entrance and the circulation pump 13 prevents the flow of water based on the resulting pressure drop in the selection of water pressure difference FR is in the direction of circulation.

Finally, figure 3, 3A shows another embodiment of a circulation system of cold water. As already shown in figure 2, fresh water is introduced into the circulation system through the inlet 15 before cooling unit 3. The cooling unit 3 is in this embodiment of the refrigeration unit (item 3) to create a cold, preferably, for example, a heat pump and connected with the drive 17 cold, in which is stored the generated cold. Drinking water circulation system is passed through the drive 17 of the cold. Due to this, it is possible to prevent unacceptable temperature rise at high water. When a small amount of water or no water flow (e.g. at night) can drive a cooling unit 3 is again cooled to the desired temperature level. Water circulation is again provided with a circulating pump 13 flows through the drive 17 of the cold and through the lifting strut 12 is fed to the top of the distribution pipe 19, which distributes water to one or more storey piping 18. In these story pipelines 18 again there are several consumers 6, in the direction of the flow at the end of the story of the pipeline 18 district and circuit included adjustable regulating valve 7, 7.1 pipeline. Fu the Ktsia this regulating valve 7, 7.1 pipeline is the same as in the above embodiments, execution, i.e. at a temperature below the set temperature adjustable regulating valve 7, 7.1 skips only the residual volume flow. When exceeding the set temperature is included in full flow, and water corresponding pipeline 18 is directed into the collector pipe 20, which supplies water to the cooling unit 3.

Figure 4 shows a controlled depending on the temperature of the valve 101, in particular regulating valve, in an embodiment in the form of a flow valve. When this insert valve 105 is inserted into the housing 102 of the valve, which has an input 103 and the output 104. Insert valve 105 is inserted with its lower end into the chamber 125 of the housing 102 of the valve. Flowing medium can enter through the bottom opening 115 of the sleeve 106 of the insert 105 of the valve and out through the radial holes 126 of the sleeve 106 and then through the outlet 104. In the sleeve 106 of the insert 105 of the valve is kept driven from the top in the drawings, the main spindle 107. Between lying inside the end of the main spindle 107 and having a bottom opening 115 of the bottom of the sleeve 106 is a spring element 113 in the form of a return spring, which rests on the bottom of the sleeve 106 and extending under the influence of temperature parallel to the axis of the spindle thermocouple 111, which in turn relies on l is adjacent the inside end of the spindle. The heating element 111 is forcibly connected, preferably connected with the adjusting element 112, which has its outer circumferential contour 128 and educated inside the sleeve 106 circuit 127 forms a loop through the gap 114, through which the flowing fluid medium can pass to the radial holes 126 of the sleeve 106 and then to the outlet 104.

Flowing medium flows through lying on the longitudinal axis of the insert 105 of the valve bottom hole 115 and washes directly into the volume flow of the heating element 111. He relies on the provided coaxial with the main spindle 107 other spindle 109 for installation (setup) temperature.

Figs.4 and 5, the valve 101 is shown in a state of "residual flow", i.e. the temperature of the flowing medium is less than or equal invariably preset temperature or installed with the spindle 109 to set the temperature to the set temperature. In this position the lock gap 114 has its lowest value. The ow rate has only an amount which is sufficient to wash thermocouple 111 and determine the actual temperature of the environment.

Figure 5 shows in enlarged scale a passing gap 114.

Figure 6 shows the controlled depending on the temperature regulating valve 101 is in the open state, i.e. the temperature of the flowing medium is higher than always (strictly) the mouth of blennow a predetermined temperature or installed with the spindle 109 to set the temperature, set temperature. On the basis of the higher temperature surrounding thermocouple 111 environment, it is, accordingly, its expanding element expands, namely, in a direction parallel to the spindle axis. The end surface of the main spindle 107 or in the example, run the spindle 109 is used for expanding thermocouple 111 as a fixed focus, so that the course of the heating element 111 is perceived recoil spring 113 and thereby takes place in the axial direction of the bottom opening 115 of the sleeve 106 of the insert 105 of the valve. Coupled with thermocouple 111 of the adjusting element 112 force behind the axial passage, thereby adjusting the gap 114 on the basis of the shift circuit 128 of the adjusting element 112 is increased relative to the circuit 127 of the sleeve 106. This increase of the entry gap 114 leads to an increase in volumetric flow.

7 shows in an enlarged scale corresponding to a fragment of 6.

On Fig and 9 shows another feature. At Fig regulating valve shown in the closed position. By turning mounted on the main spindle 107 hand wheel 108 is shifted in the axial direction is installed without the possibility of turning on the top of the sleeve 117 powered hub 116 by using a running thread on the main spindle 107. When closing the valve 101 is happening is the axial displacement of the drive sleeve 116 in the direction of the bottom opening 115 of the sleeve 106 of the valve insert 105, when mounted on a powered hub 116 of the adjusting element 112 is fond in the same direction together with thermocouple 111 against the force of a return spring 113. The shift is up until the o-ring 118, which is fixed on the adjusting element 112 will not sit on the saddle adjustment of the gap 114, and thus until you cover the volumetric flow.

The relevant portion is shown in an enlarged scale in figure 9.

Figure 10 and 11 shows the installation temperature. Installation is carried out by using the provided coaxial with the main spindle spindle 107 109 installation temperature, which at its upper outer end side is marked. On the main spindle 107 installed on top ring 110 scale with the corresponding temperature range. By turning the spindle 109 installation temperature relative to the main spindle can be installed marking spindle set temperature to a certain temperature on the ring 110 of the scale. The rotary movement of the spindle 109 installation temperature is converted using threaded axial displacement relative to the main spindle 107. Due to the axial movement of the spindle 109 set temperature is shifted in accordance with the set temperature, the position adjacent to the inside clap is on 101 end side of the spindle 109 installation temperature thermocouple 111.

On Fig shows an embodiment, which is provided by connecting the valve 119 for circular pipes. Input connection 120 and the output connection 121 include connecting the valve 119 in the system piping drinking water. In the direction of flow of the medium indicated by the arrows, for the input connection 120 branches off output connection 122 to the circular pipeline with one or more consumers. After connecting with consumers annular pipe through the inlet connection 123 is connected with the connecting valve 119. After the input connection 123 of the annular pipe is a valve insert 105. Thus, the housing connecting the valve forms a receiving element for the valve insert 105 and provides the corresponding inflow and outflow.

Using the appropriate valve insert 105 volumetric flow is reduced to a residual flow until the temperature of the flowing medium is installed (configured) on the valve insert 105 temperature. In the direction of flow after the valve insert 105 connection is again (ends) in the case of the connection of the valve 119. In the immediate example of execution of the connection between the connections 120 and 121 and branches to the circular pipeline 122 and 123 and it can be integrated hydraulic with rotisserie, for example, in the shown example, the execution of the throttle valve 124. The installation of such connecting valve 119 into the circulation system of cold water provides the possibility of hydraulic balancing the flow resistance in different parts of the installation. On Fig shows only one principal location of such components.

Finally, on Fig shows the possibility of applying the corresponding valve insertion bore 105 in the valve according to figure 4, or in connection valve 119, according Fig.

The invention is not limited to the shown examples of implementation and may change within the framework of disclosure.
