Definitions

  • the present invention refers to a water and energy economizer whose purpose is to provide a device that installed in the water network just before any type of tap and connecting it to the water inlets of the same, allow to save the amount of water that is usually wasted from when hot water is requested from a tap until it reaches the desired temperature, also preventing the energy used to heat the water until it reaches the programmed temperature is wasted.
  • Patent ES 2299337 addresses the aforementioned problem, detailing an intelligent water saving management system characterized in that when the opening of the corresponding tap is detected, a sensor controls the temperature of the water that reaches it, so that if said temperature is below a certain temperature, the water is recirculated to a boiler where it is stored until The sensor detects an optimum temperature.
  • This patent has drawbacks related to the fact that it requires an auxiliary tank or boiler where the water is stored until the optimum temperature is reached, determining greater complexity in the installation and an increase in its cost.
  • a sanitary installation for water saving is detailed that is characterized in that the taps have three ducts, one of cold water, another of hot water and another of return, so that within there is a chamber with a thermostatic valve, which if it does not receive the determined temperature does not open, causing the hot water but which does not yet have the desired temperature to be sent back to the boiler through the return duct. Once the water reaches the corresponding temperature, the valve opens allowing the passage of hot water to another chamber where it can be mixed with cold water and out through the tap.
  • the The invention consists of a water and energy economizer applicable to taps, showers and in general elements with hot water outlet and cold water outlet; the hot water coming from a hot water outlet of a boiler, heater or the like and the cold water of a network conduit that also feeds the boiler or the like.
  • an economizer circuit is inserted in its water intakes that has:
  • the invention has relative advantages in that it provides a water and energy economizer that allows all the water not yet sufficiently hot and unwanted to return to the network by means of a closed circuit instead of being wasted .
  • the water saving that can be obtained with the invention, applying statistical data of water consumption in Spain, would be between 20 and 30 1 of water per person and day, and considering that the per capita water consumption in Spain is situated in 170 1 / day, represents a saving of between 12% and 17%.
  • the water and energy economizer of the present invention also has the advantage of not requiring additional storage device, since the return of the water to the undesired temperature is made directly to the network.
  • a special tap is not required for its operation in the invention, being able to be installed in a conventional water network and being compatible with any type of tap on the market such as mixer taps, mixers or others.
  • Figure 1 Schematically represents by means of a functional block diagram a water and energy saving circuit made according to the present invention.
  • Figure 2. Schematically represents a water installation that employs two water and energy saving circuits, each of them being the one represented in the previous figure 1.
  • DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION Next, a description is made of an example of the invention referring to the numbering adopted in the figures.
  • the economizer circuit 10 of the present example is applied to taps 11, showers 12 and in general element with hot water outlet 3 and cold water outlet 4, as can be seen in Figure 2.
  • the hot water comes from a hot water outlet of a boiler, heater or the like 15 and the cold water of a network conduit that also feeds that boiler or the like fifteen.
  • a cold water inlet of network 2 connected with a cold water outlet 4 towards the tap or the like 11, 12 through a cold water solenoid valve 9.
  • said hot water solenoid valve 8 has a return circuit outlet 5 that connects with a return water line connected in proximity to the boiler or the like 15 to its cold water outlet.
  • circuit 10 of the present example has the following operation:
  • the corresponding flow detector 6 detects the passage of water and activates the temperature detector 7. Immediately, the detector of temperature 7 makes a reading of the water temperature and if it does not reach the desired temperature it sends a signal to the solenoid valves 8 and 9, which close the water passage to the exits 3 and 4, corresponding to the hot water outlets and cold respectively of tap 11 or the like; by simultaneously driving the discharge pump 13. Said discharge pump 13 causes the water not yet hot enough to exit the outlet 5 corresponding to the return circuit output and reach the network just before the cold water enters the boiler 15 to be reused by it, as can be seen in figure 2.
  • the flow detector 6 does not circulate water and therefore the temperature detector 7 is not activated, so that the solenoid valves 8 and 9 do not close, thus allowing the output of water through the outlet to the cold water outlet 4.
  • the temperature detector 7 would not be activated and therefore the solenoid valves 8 and 9 would remain open allowing water to pass through them and thus avoiding running out of water supply.

Abstract

A proximité de chaque robinet, ou élément auquel on souhaite appliquer l'économiseur, est intercalé au niveau de leurs prises d'eau un circuit (10) qui présente: une entrée d'eau froide du réseau (2) raccordée à une sortie d'eau froide (4) vers le robinet par l'intermédiaire d'une électrovanne d'eau froide (9); une entrée d'eau chaude (1) provenant d'une chaudière ou analogue, raccordée à une sortie d'eau chaude (3) vers le robinet par l'intermédiaire d'un détecteur de débit (6), un détecteur de température (7) et une électrovanne d'eau chaude (8) qui présente une sortie vers un circuit de retour (5) raccordée à une conduite d'eau de retour reliée à proximité de la chaudière ou analogue à sa prise d'eau froide. A proximité du raccordement entre ladite prise et ladite conduite se trouvent des vannes anti-retour respectives, ladite conduite présentant en outre une pompe à impulsion.
