Description

Technical field

[0001] The present invention relates to a water management system for water distribution systems. State of the art

[0002] Water distribution systems typically include a section designed to supply water to a point of use and a section designed to collect greywater and wastewater from these points of use. Currently, there are several issues regarding how water is managed in water distribution systems. One of the main problems concerns the efficiency of the water distribution system, that is, the ratio between the water entering the system and the water ultimately used. An inefficient system results in water waste, which is a resource that should be conserved. Additional problems relate to water hygiene, as hygiene is essential to ensuring the safe operation of the water distribution system.

[0003] Several solutions have been proposed to more or less solve some of these existing problems.

[0004] Document US2010 / 126604 discloses a hot water distribution system on demand, which has several disadvantages. According to the situation described for the temperature sensor in document US2010 / 126604, the water is recirculated throughout the entire system, not just in the branch at the point of use, using twice the energy required to deliver the hot water to the point of use. Furthermore, the system disclosed in document US2010 / 126604 only delivers hot water to a specific tap, making the use of a tap-connect valve essential for use with other taps in the system. Additionally, the system's operation must be activated by a tap or a specific point to which the user must go each time they wish to use the technology. Similarly, a trigger is required for each controlled valve.

[0005] Document US2010 / 096018 discloses an instant hot water supply system that has several drawbacks. The system's operation relies on a return line and a water storage tank for effective recirculation, making it unsuitable for traditional installations without a return line, a storage tank, or with instantaneous water heaters. The system only stops the cycle when the water reaches a certain temperature, lacking pressure or operating time sensors or actuators. This could cause the cycle to run indefinitely if the water heater fails to produce hot water for any reason.

[0006] Document US2004 / 182439 discloses an intelligent device and system for improving household water usage. However, this system also has some drawbacks. The system requires a recirculation module, which is installed at each hot water outlet in the system. Furthermore, the system requires the use of specially modified faucets or an external recirculation module, both for each outlet. Another limitation is the need for a hot water storage tank to achieve the desired effect, making it incompatible with tankless water heaters or heating appliances without a storage tank.

[0025] In one embodiment, the communication module is configured to enable different types of communication, such as GPRS, wired connection, WLAN, and / or radio, while the remaining modules of the water management system can only be connected to each other or to the communication module wirelessly. In this case, the user can communicate with the water management system via the communication module, which in turn communicates wirelessly with the other modules to implement the desired action as specified by the user.

[0033] In one embodiment, the activation condition and / or the stop condition is received by the first, second, third, fourth and / or fifth transmitter-receiver.

[0034] The existence of different options for the activation and shutdown conditions advantageously provides diverse operating possibilities. Furthermore, the water management system is less susceptible to errors due to internal or external circumstances, since either the user, via the user interface or an external actuator, or the system itself, based on data from the detection devices, an external control device, or a pre-programmed time routine, is able to interrupt the operation of the water management system, for example, when the desired operation has ended, if the desired operation is not being carried out, or if an operational error is anticipated.

[0038] The activation condition and the stop condition can originate from the user or from the water management system itself, for example: - by a user of the water management system, such as by means of the operation of: an external control device, the user interface, at least one detection means and / or an external actuator; - by an element of the water management system, without user intervention and automatically, such as: (i) in response to a pre-programmed time routine in the control means according to at least one variable controlled by the time control element, and / or (ii) in response to information received from at least one detection means.

[0039] The activation condition and / or the stop condition can be received in the control system directly and / or via the first, second, third, fourth and / or fifth transmitter / receiver.

[0040] The third controller can be trained to detect and process a variety of different activation conditions, which determine a variety of different actions to be performed.

[0041] In one embodiment, the control means are configured to perform the following step prior to step a): performing user recognition based on data received from at least one biometric sensor and / or the user interface, for example, by checking a password entered using the user interface against a database. Advantageously, prior user recognition allows for the adaptation of operating parameters to each individual, as well as the restriction of available actions to specific users.

[0044] In one embodiment, the functional extension module comprises a container for introducing at least one additive to be mixed with the water flow during operation, and at least one second valve is arranged such that: - in a first position, the aforementioned second valve prevents the opening of the container for the introduction of additives and allows fluid communication between the container and at least one pipe of the water distribution system, thus allowing the mixing of water circulating through the pipe with the at least one additive present in the container and producing a fluid with altered properties; and - in a second position, the aforementioned second valve allows the introduction of additives into the container and prevents fluid communication between the container and the pipes of the water distribution system, thus ensuring that the water flow passing through the functional expansion module does not leak out of the container while the container is being operated by the user.

[0045] The additive can be solid or liquid. Non-limiting examples of additives to be introduced into the container include those with anti-limescale properties, disinfectant properties, biocidal properties, cleaning properties, and / or properties for reducing the amount of chlorine.

[0046] Advantageously, dosing an additive for distribution via the water distribution system or a part thereof provides the following non-limiting possibilities: anti-limescale effects, the elimination of bad odors, the elimination of microorganisms and / or the purification of the chemical and organoleptic properties of the process water.

[0047] In an example where the additive is soap, the soap is mixed with the water flow during use, thus transferring its properties to the water. This allows the user to receive soapy water directly from the tap (for example, during a shower), and once the effect of the dosed soap wears off, the flushing process continues automatically. In this example, the introduction of soap into the water flow can be automatically scheduled according to a pre-programmed routine, activated by turning on the water at a point of use or by the user, among other methods.

[0050] In one embodiment, the activation module can be implemented as a pulse generator, as a remote control, and integrated into a tap or another element of the water distribution system.

[0051] The water management system of the present invention can contain a single module of each type or more than one module of one or more types, for example a plurality of modules of the same type arranged at different locations in the water distribution system.

[0052] In one embodiment, the water management system comprises a plurality of pump modules. In one embodiment, the pump modules are coupled together in series or in parallel, so that the working flow rate and / or the pressure of the fluid is increased depending on the number of pump modules in operation.

[0053] In one embodiment, the water management system comprises a bypass line parallel to the pump module and a valve, such that during operation of the pump module, the water circulates through the pump module and during the consumption cycle the valve is actuated to circulate the fluid through the bypass line, thus reducing the operating time of the pump module and extending its service life.

Some examples are provided, such as water more suitable for human consumption, water with special properties for toilet use, or water containing a cleaning or preservative product for maintaining the pipes of the water distribution system. In an example where a cleaning additive is introduced, the present embodiment allows for the cleaning of the pipes. In an embodiment where a fluorescent fluid is recirculated, the present embodiment allows for the detection of leaks.

[0083] In an example where the additive is soap, the soap is mixed with the water flow during use, thus transferring its properties to the water. This allows the user to receive soapy water directly from the tap (for example, during a shower). Once the effect of the dosed soap wears off, the flushing process continues automatically. In this example, the introduction of soap into the water flow can be automatically timed according to a pre-programmed routine, activated by turning on the water flow at a point of use or by the user, among other methods.

[0089] Advantageously, this embodiment allows the management of heating and / or recirculation networks via heating systems which include pipes filled with heat transfer fluids (water or others) in a closed circuit, including sanitary hot water return circuits by means of a parallel or concentric double branch, so that the user can manage the ambient conditions of his house or company premises and / or preheat the water before consumption by means of water recirculation until the stop condition is met.

[0090] In one embodiment, the pump module is located: a) at a point on the additional greywater utilization pipe which is connected to the water storage tank or pressure flush valve of a sanitary fixture from which the greywater flows; or b) at a point on the additional greywater utilization pipe which is connected to a connection point of the water supply system which is connected to the water storage tank or pressure flush valve of a sanitary fixture from which greywater flows; or c) at a point on the additional greywater utilization pipe which is connected to the greywater tank; the at least one controlled element comprises the pumping system; in step d) the first control is configured to command the pumping system to start and maintain operation in order to pump the greywater exiting through the drain to the additional greywater recovery pipe and / or to the tank, circulating it through the additional greywater recovery pipe for use in another sanitary fixture; wherein the stop condition is one or more of the following: a) a flow and / or pressure measurement of the first or second detection means which meets a predetermined condition; b) an operating time which is greater than a predetermined value; wherein in step f), when the occurrence of the stop condition is detected, the first controller is configured to command the pump system to stop operation.

[0091] Advantageously, this embodiment prevents the waste of drinking water when a toilet water tank is emptied and instead allows the use of greywater draining from nearby sanitary fixtures such as a toilet, bidet, shower, bathtub, or sink. Advantageously, the use of a greywater tank ensures that when the pump module starts operating, a certain amount of water is available to transfer to the water tank.

[0092] In one embodiment, the connection module is: - in the hot water branch before the water inlet of the water heater, - in the hot water branch, integrated into the water heater, - in the hot water branch after the water outlet of the water heater, - in the cold water branch, or - in the greywater recycling pipe, arranged and at least one first valve has: - a first position in which the passage of water to the greywater usage pipe is permitted, and - a second position in which the passage of water to the greywater usage pipe is prevented.

[0094] Advantageously, this embodiment detects and prevents unwanted water consumption in the water distribution system, for example, consumption when the user is not present, or consumption caused by damage such as leaks, bridging, impacts, and other defects in the water distribution system. The damage to the system is thereby limited to the volume of water within the pipes at the time the activation condition is detected.

[0095] Non-restrictive examples of undesired water flow include: water consumption when there are no users to use the water distribution system (a condition which can be communicated by the user via the user interface or via an external control device), prolonged water consumption over a specified period, water consumption according to predetermined consumption rules specified on the control devices, or an entry condition into the water distribution system, measured by at least one water pressure and / or temperature sensor, which differs from predetermined values ​​specified on the control devices.

[0096] In one embodiment, the communication module is designed to issue a message regarding external emergency resources, informing about a fault in the water distribution system.

[0100] In one embodiment, the water distribution system comprises one or more additional connection modules which are arranged to establish a connection between two pipes of the water distribution system, wherein the position of the at least one first valve allows said connection to be opened and closed.

[0101] Advantageously, installing at least one additional connection module at an intermediate point in a closed-loop water distribution system allows the system to be divided so that operation of the water distribution system or the water management system only covers the sections enabled by activating at least one valve of the additional connection module. For example, a double-branch system covering an entire floor of a building has a connection module located halfway across its cover, connecting two sections of a flow pipe to one section of a return pipe. During the initial circulation operation via the double branch, water flows throughout the entire floor in both directions.If the connection module is installed halfway through its cover, a new flow and return connection is created midway, effectively shutting off the cycle. This feature reduces the time and energy used in the cycle. It is compatible with other functions provided by the water management system of the present invention, allowing for the performance of a specific function within a portion of the water distribution system.

[0102] Furthermore, providing at least one additional connection module allows for the creation of additional controlled flow lines, thus avoiding the need to pass through certain elements of the water distribution system, if desired, while protecting these elements from wear and tear.
