Definitions

  • the invention relates to an apparatus for heating and producing an energy storage fluid, such as hot water, comprising a reservoir in which said fluid is contained, a heat source for heating the fluid, and an insulating enclosure in which the tank is placed.
  • an energy storage fluid such as hot water
  • the fluid example selected is water.
  • 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 to the radiator.
  • the present invention aims to overcome the disadvantages listed above.
  • it aims to provide an apparatus for heating and producing an energy storage fluid that is simple in structure, economical and that allows the use of the hot fluid reservoir as a heating source.
  • 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 reservoir comprising at least one zone which is not in direct contact with the wall of the enclosure, this zone communicating with the outside of this insulating enclosure and being in view of a window opening that includes the wall of said enclosure, opening provided with at least one shutter for closing on demand, characterized in that said flap is constituted by a vertical portion of the enclosure which is movable in translation relative to a second fixed part of the enclosure, these two parts being coaxial, but of different diameter, and that the portion of the reservoir which is opposite the moving part of said component is surrounded by a helical winding of heat exchange connected to a thermal source.
  • This apparatus 1 comprises a tank 2 of hot water of known type, for example metal and a capacity of a hundred liters.
  • This reservoir contains a heating means (not shown) of water which consists of an electrical resistance.
  • a heating means (not shown) of water which consists of an electrical resistance.
  • any other heating means integrated in the tank or located outside thereof can be considered. This is for example one and / or the other of the following means: gas burner or condenser of a heat pump or an exchanger connected to a power source (boiler, heat pump, solar panel , stove, etc.)
  • 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 material that constitutes the insulating enclosure 3 is polyurethane foam. It is of course possible to use other materials such as polypropylene, extruded polystyrene, expanded polystyrene, phenolic foam, or any type of material that has low thermal conductivity ( ⁇ less than 0.1 W / (mK).
  • the side wall of the enclosure consists of two parts, in this case a first portion 32 'which is movable in translation relative to a second fixed portion 32 of the enclosure.
  • these two parts 32 and 32 ' are coaxial, but of different diameter.
  • the portion 32 ' has the smallest diameter.
  • the movable portion 32 ' is the one with the largest diameter and is moved upwards to discover the surface of the tank.
  • the space above the fixed part 32 is used to set up a helical external heat exchanger 7.
  • the "radiator" which heats the outside air is constituted by the wall of the tank 2 and the exchanger 7.
  • the exchanger may have another shape (for example consisting of parallel tubes). At the base, this exchanger is intended to heat the water of the balloon from a source of energy outside the storage tank
  • the apparatus of the figure 4 is the same type. However, the exchanger 7 is connected via pipes 70 and 71 and a pump 72 to a solar panel P.
  • the exchanger 7 is connected to a heat pump 8 of known type, which will not be detailed here.
  • This heat pump rests on the upper part 30 of the enclosure, so that the footprint of the device is the same as in the embodiments described above.
  • heat pump is remote from the tank, with a suitable connection.
  • This exchanger contains refrigerant or a heat transfer fluid that recovers heat pump calories and injects them into the tank water.
  • the embodiment of the figure 6 is identical to the previous one, except that a condenser 9 has been mounted in series with the heat pump 8, mounted at the opening disengaged by the sliding part 32.
  • the exchanger 7 stops heating the water and then operates a reheating of the surrounding air, through the condenser 9 or a gas cooler.
  • the figure 7 represents a variant of the apparatus of the figure 6 , in which is interposed between the wall of the tank 2 and the condenser 9, a fan 6 whose essential function is to cause a stirring of the air to be heated.
  • the figure 8 represents an alternative embodiment of the apparatus of the figure 4 , in which a fan 6 is placed in the opening 320, as well as an additional heat exchanger 9 '.
  • the exchanger 7 is connected to the solar panel P via this adding heat exchanger 9 'and the pump 72.
  • the variant of the figure 9 differs from that of figure 8 in that the solar panel P is replaced by a gas or oil burner B.
  • the system can also be coupled to a solar panel or gas boiler.
  • the exchanger is not refrigerating but hydraulic.
  • the circuit or connection between the heat pump and the tank heat exchanger can be hydraulic or refrigerating.
