Definitions

  • the invention relates to an apparatus for heating and producing an energy storage fluid, which comprises a reservoir in which said fluid is contained, a heat source for heating the fluid, and an insulating enclosure in which is placed The reservoir.
  • the fluid in question is water and this is the example that will be taken throughout the present application.
  • hot water tank In common parlance, such apparatus is generally referred to as "hot water tank”.
  • Such a tank whose capacity may be from a few tens to a few hundred liters, provides hot water.
  • this tank is surrounded by a thermally insulating enclosure, in order to minimize heat loss.
  • the tank can also be used to heat a space such as a living room and uses for this purpose a hydraulic heat exchanger.
  • the heat exchanger transfers heat from the reservoir to heat "transmitters”, ie radiators, via a network of tubes, a pump, etc.
  • This system is complex and a high cost. In addition, its performance is low due to heat loss and radiator.
  • the present invention aims to overcome the disadvantages listed above.
  • the present invention relates to an apparatus for heating and producing an energy storage fluid such as hot water, which comprises a reservoir in which said fluid is contained, a heat source for heating the fluid. , and an insulating enclosure in which the reservoir is placed, said thermal source being placed inside the reservoir or outside said enclosure, and the wall of the enclosure being in contact with said reservoir at the except for at least one hollow region constituting a channel formed in the wall of said enclosure, the opposite ends of this channel respectively communicating with an inlet and an air outlet.
  • an energy storage fluid such as hot water
  • This apparatus is remarkable in that said at least one channel has a helical shape
  • figure 1 is a simplified view, in vertical longitudinal section, of an embodiment of the heating apparatus and hot water production according to the invention.
  • This device 1 of the figure 1 comprises a reservoir 2 of energy storage fluid (for example hot water), of known type, for example metal and a capacity of a hundred liters. It could, of course, be of higher or lower capacity.
  • energy storage fluid for example hot water
  • the reservoir is disposed inside and surrounded by an enclosure 3 of material which is a thermal insulator, this, in order to lose the minimum of calories stored by the water.
  • the fluid contained in the reservoir 2 is heated by a heat source 4 placed inside the reservoir 2 (as shown in the figures) or outside the enclosure 3.
  • the top of the enclosure 3 is referenced 30, while its base is referenced 31. It rests on a base S. Its side wall 32 has an internal surface generally complementary to that 22 of the reservoir 2.
  • the speaker could sit directly on the floor or be attached to a wall.
  • the material that constitutes the insulating enclosure 3 is polyurethane foam.
  • polyurethane foam Of course, other materials such as Neopor (registered trademark), polypropylene, extruded or expanded polystyrene, phenolic foam or any type of material having a low thermal conductivity ( ⁇ less than 0.1 W / (mK)).
  • the top of the chamber 3 supports a heat pump 7 of a type known per se, which is connected to a helicoidal heat exchanger (not shown), also of known type, placed in the tank 2. In a not shown embodiment, it could be placed around the outer wall of the tank.
  • the section of the channel 33 is semicircular. However, any other form can be considered. As an indication, it could be a rectangular, elliptical, rectangular section with rounded corners, triangular, trapezoidal, or a combination of these forms.
  • the channel 33 has the particularity of having a helical shape (see the arrows of the figure 1 ) whose low and high ends respectively communicate with openings 321 and 322.
  • the opening 321 serves as an outside air inlet, while the opening 322 serves as an outlet.
  • the opening 321 serves as an outside air inlet. This air is free to circulate in the space E, while licking the wall of the tank 2. During this generally ascending movement, it heats and exits the apparatus through the opening 322 forming an outlet.
  • both the opening 321 and the opening 322 can be equipped with a grid or any other equivalent means forming a filter, so that pollutants and / or insects do not infiltrate inside. of the device.
  • the location of the openings 321 and 322 may be different from that described above. However, the opening 322 will preferably be at a height higher than the opening 321, due to the ability of the hot air to rise naturally.
  • Such an arrangement is particularly effective because the flow of air that rushes into the channel 33 travels a long path to open at the outlet opening, along which the heat exchange is maximum.
