Definitions

  • the present invention relates to a water and energy economizer which purpose is to provide a device that installed in the water system just before any type of tap and being connected to water intakes thereof, allows saving the amount of water that is normally wasted since the hot water is demanded from a tap until this reaches the desired temperature, also avoiding the energy used to heat the water until reaching the programmed temperature from being wasted.
  • the patent ES 2299337 addresses the aforementioned problems, detailing a water saving intelligent management system characterized in that when detecting the aperture of the corresponding tap, a sensor controls the water temperature that reaches it, so that if said temperature is below certain temperature, the water is recirculated toward a boiler drum wherein is stored until the sensor detects an optimum temperature.
  • Said patent presents drawbacks regarding to require an auxiliary tank or boiler drum wherein the water is going to be stored until reaching the optimum temperature, determining a greater complexity in the installation and an increasing on Its cost.
  • a sanitary installation for water saving is detailed, characterized in that the taps have three conduits, one for cold water, other for hot water and another for returning, so that a chamber with a thermostatic valve is therein, which does not open if not receives the certain temperature, causing the hot water but not with the desired temperature yet be sent back to the boiler through the return conduit. Once the water reaches the corresponding temperature, the valve opens allowing hot water to flow to another chamber wherein can be mixed with cold water and comes out through the tap.
  • the invention consists of a water and energy economizer applied to taps, showers and in general to elements with hot water outlet and cold water outlet; coming the hot water from a hot water outlet of a boiler, heater or similar, and the cold water from a pipeline system that also feeds the boiler or similar.
  • Novelty In proximity to each tap, shower or similar element to which the economizer is desired to be applied, an economizer system is sandwiched into its water intakes, presenting:
  • the invention presents advantages relating to provide a water and energy economizer that allows all the water not hot enough yet and unwanted returns to the system by means of a closed loop circuit instead of being wasted.
  • Water saving can be obtained with the invention, by applying statistical data of water consumption in Spain, it would be between 20 and 30 L of water per person per day, and considering that the per capita water consumption in Spain is 170 L/day, it supposes a saving between 12% and 17%.
  • the water and energy economizer of the present invention further presents the advantage of not requiring additional storage device, since the water return to the desired temperature Is made directly to the system.
  • the invention does not require a special tap for its operation, being able to be installed in a conventional water system and being compatible with any type of tap currently available in the market, such as, single lever, mixer, or other taps.
  • the economizer circuit 10 of the present example is applied to taps 11, showers 12 and in general to elements with hot water outlet 3 and cold water outlet 4, as can be seen from figure 2 .
  • the hot water comes from a hot water outlet of a boiler, heater or similar 15, and the cold water from a pipeline system that also feeds that boiler or similar 15.
  • the economizer circuit In proximity to each tap 11, shower 12 or similar element to which the economizer wants to be applied, the economizer circuit is sandwiched into its water intakes 10, which includes, as can be seen In figure 1 , the following elements:
  • a cold water inlet 2 of the system connected with a cold water outlet 4 to the tap or the like 11,12 through a cold water electrovalve 9.
  • the referred hot water electrovalve 8 has an outlet to return circuit 5 that connects with a return water pipeline joined in proximity to the boiler or similar 15 to its cold water intake.
  • the circuit 10 of the present example presents the following operation:
  • the corresponding flowrate detector 6 detects the water flow and activates the temperature detector 7. Immediately, the temperature detector 7 reads the water temperature and if this does not reach the desired temperature sends a signal to the electrovalves 8 and 9, which cuts off the water flow to outlets 3 and 4, corresponding to hot and cold water intakes, respectively, of the tap 11 or the like, simultaneously driving the impulse pump 13. Said impulse pump 13 causes the water not hot enough yet comes out through outlet 5 corresponding to the return circuit outlet and reaches the system just before the cold water inlet of the boiler 15 in order to be reused by it, such as can be seen in figure 2 .
  • the temperature detector 7 At the time in that the temperature detector 7 detects that the temperature of hot water is the desired one drives the electrovalve 8 to allow the hot water to flow through the outlet 3, and the electrovalve 9 to enable cold water to flow through the outlet 4, while disconnecting the impulse pump 13.
  • the temperature detector 7 would not be activated and therefore the electrovalves 8 and 9 would remain open allowing the water to flow through them and thus avoiding running out of water.
