Definitions

  • the present invention relates to a system for stopping water flow in water use installations, and more specifically to a system meant to prevent the loss of cold water and the resulting energy cost when requesting hot water at a point of use.
  • the object of the invention is to provide an environmentally-friendly manner to save water without sacrificing comfort, as well as optimising water and energy resources by the advantage of the cold and lukewarm water that is typically and inevitably wasted when opening a hot water faucet, for example, until the desired water temperature is reached, and also provides savings in the water purification system and in the energy, whether by gas or electricity, used by the corresponding boiler needed to heat the water.
  • a further object of the invention is to provide a device that can be fitted in any existing installation in a simple manner, with fully automatic operation, without the need for electronic devices or circuits, and with an extremely simple electrical circuit.
  • the drawback in this type of buildings and households is that the main pipe acts as an individual boiler, so that when hot water is required the faucet is opened and it is necessary to wait for the hot water to reach the main pipes of the requesting household, wasting the cold water in these pipes.
  • the pipes of each household function as segments left out of the recirculation, as in the previous example.
  • the system of the invention is based on installing a thermostatic bypass between the hot water pipe and the cold water pipe, fitted immediately before the water outlet faucet (avoiding pipe segments out of the recirculation), so that between said bypass and the boiler the hot water circuit contains the circulation pump and a flow switch able to act on a relay that governs the operation of the pump.
  • the corresponding flow meter of the boiler detects the water flow and starts the boiler, while the flow switch also detects the flow and turns on the circulation pump, so that the water sent from the boiler through the hot water pipe passes through the pump, the flow switch and reaches the bypass, passing through it and returning to the boiler in the cold water pipe, establishing a closed-circuit recirculation without reaching the faucet, as the water is recirculated at the bypass, the thermostatic valve of the bypass operating so that when the desired temperature is reached this thermostatic valve will close and the hot water flow stops, making the flow switch turn off the circulation pump and stopping the boiler, so that the circuit will contain the hot water and be resting, the boiler then operating in the conventional manner, so that hot water can be obtained directly at the time of opening said faucet.
  • the flow switch detects the water flow and closes a switch that sends power to a relay, which in turn closes some greater-power switches that feed the pump.
  • the pump will keep the flow switch closed even if the faucet is closed, as water is being received through the thermostatic bypass and the cold water pipe, so that the water flow does not stop.
  • thermostatic bypass When the programmed temperature is reached the thermostatic bypass will close, stopping the water flow and opening the relay, thus stopping the circulation pump and the boiler.
  • the circulation pump will start again (not without any specific function, as the bypass is closed), driving hot water through the corresponding pipe to the faucet, the boiler then operating in the conventional manner, that is, if the hot water faucet is opened, the boiler starts, and if it is closed the boiler turns off.
  • the water in the pipe will cool, and the bypass will have returned to its standby position, open.
  • the recirculation can be activated again by opening and c losing the faucet in the hot water position.
  • opening and closing the faucet will start the boiler until the temperature set at the corresponding point of use (the faucet) is reached, at which time if the faucet is opened again hot water will flow immediately, and the thermostatic bypass will be turned off.
  • fitting a thermostatic bypass at each point of use of a household means that the recirculation will start each time a faucet is opened and closed, the recirculated water passing by the closest bypass that presents the least resistance to water flow, until the water reaches the preset temperature, when the bypass will close, and so on for all existing bypasses until the last one is closed, stopping the flow.
  • the boiler and the pump flow switch will detect that flow has stopped and will therefore turn off, leaving the entire installation with hot water available at all points of use, regardless of whether there are several main circuits, as in large homes with more than one main circuit, or of points of use distant from the main circuit.
  • the installation of the invention includes, as an essential element, a thermostatic bypass (1), with a thermostatic element (2) and a check valve (3), said bypass (1) being connected between the corresponding hot water pipe (4) and the cold water pipe (5), a point of consumption such as a faucet (6), as shown clearly in figure 1 , having been fitted previously.
  • the cold water pipe (5) is naturally connected to the corresponding outlet (7) and to the heating boiler (8), from which the hot water pipe (4) runs, and in which the circulation pump (9) is installed, governed by a relay (10) that is activated by a flow switch (11), as will be described below, and which as the circulation pump (9) itself is fitted in the hot water pipe (4).
  • the electrical power supply for the flow switch (11) and the relay (10) is provided by the corresponding power grid (12).
  • the operation can be summarised as follows: when a user decides to obtain hot water at the faucet (6), or example to take a shower, said faucet (6) must be opened and closed in the hot water position, thereby initiating the hot water recirculation through the hot water pipe (4), the bypass (1), the cold water pipe (5), the water then returning to the boiler (8) so that when the thermostatic bypass reaches the desired water temperature it closes, stopping water flow through it so that there is hot water available in the faucet (6) when it is opened.
  • the bypass (1) provided at the point of use of the water can be manufactured in many different ways, such as an independent part that can be coupled to any existing faucet, as an element integrated in the faucet, whether single lever or thermostatic, can include a thermostatic valve, and electric valve, a manual valve, and can have different shapes and appearances, as well as be made of different materials.
