Definitions

  • the present invention relates to a hot water tank and a method of heating said tank.
  • the technical sector of the invention is that of devices for the production of hot water from storage tanks and other similar devices.
  • the hot water accumulators currently on the market and whatever their capacity have a relatively short lifespan of the order of ten years regardless of the material from which they are made: copper or stainless steel or coatings interiors with which they are fitted: enamel or any other anti-corrosion coating.
  • such accumulators are designed to heat a body of water contained in a tank in which is established, during the withdrawal of hot water, a supply of cold water by circulation in the tank, which modifies the pH of water and correlatively leads to degradation by premature corrosion and / or scaling whose corollary is a relatively short lifespan: ten years.
  • the hot water draw-off tube which has the function of capturing the water in the upper part of the tank, is disposed inside of it and is at contact with the body of water located at the bottom of said tank, which is tempered by the arrival of cold water admitted to the accumulator. So the hot water drawn from the accumulator is at a lower temperature than that captured at the top due to the heat losses inherent in the crossing of said tube in the body of temperate water.
  • the present invention aims to remedy these drawbacks
  • the objective of the present invention is a hot water production tank made from common materials and therefore a very reasonable cost price but which due to its design can have a useful life of the order three times that of hot water storage tanks currently on the market.
  • the hot water tank for the application of said process is characterized in that said outlet pipe passes through the tank at its upper part and extends parallel to the wall of the tank through the heat-insulating layer of the tank. insulated envelope to reach the lower part thereof and by the fact that the probe of said thermostatic means is arranged in a thermowell attached to the part of the cold water inlet pipe located inside tank.
  • the hot water outlet pipe which passes through the heat-insulating layer is arranged in an insulating sheath.
  • the thermal insulation which surrounds the tank inside the outer envelope is made of expanded polyurethane, and the balloon according to the invention is characterized in that the tank is enveloped by a layer of mineral wool put in the contact with the tank wall.
  • Said balloon further comprises between the layer of mineral wool and the expanded polyurethane, a layer of compact felt to perfect the thermal insulation of the tank and protect the expanded polyurethane taking into account the high temperature of the water contained in the tank and which is around 85 ° C.
  • this comprises on the one hand a first support of a U-shaped profile comprising holes for the passage of fixing means to said wall and on the other hand of a second support of a U-shaped profile and corresponding to said first support to be connected together by fixing means, which second support is fixed to the tank by at least two metal belts which tightly surround the insulating layer of compact felt which envelops the shell of said tank.
  • the result of the invention is a hot water production tank of a new design allowing better thermal efficiency and a longer service life compared to similar devices currently known.
  • FIG. 1 of the drawing illustrates an embodiment of a hot water production tank according to the invention.
  • This consists of a tank 1 made of black sheet metal and comprising a cylindrical shell la and two domed bottoms, for example elliptical 1c / 1d.
  • the two bottoms 1c / 1d are assembled by welding to the ferrule 1.
  • Said tank 1 is disposed inside a heat-insulated envelope 2, which consists of a cylindrical part 2a at the ends of which two covers 2b / 2c fit together.
  • This envelope is made of thin sheet steel and is covered with a protective coating, for example a paint or an enamel.
  • the tank 1 and the casing 2 are coaxial and the convex bottoms 1b / 1c of the tank are situated substantially at the level of the interlockings of the covers 2b / 2c.
  • the latter is enveloped by a layer of mineral wool 3 , for example glass or rock wool or quartz wool, which layer of mineral wool is itself covered by a layer of compact insulating felt 4.
  • mineral wool 3 for example glass or rock wool or quartz wool
  • a heat exchanger 6 Inside the tank 1 is arranged a heat exchanger 6. As illustrated in the drawing, in Figure 1 and in a non-limiting embodiment, said exchanger is made of red copper and takes the form of 'a helical tubular coil which extends over the height of the tank 1 between the two curved bottoms 1b / 1c.
  • tank could just as easily receive a heat exchanger adopting any other form: annular, tube bundle or other, etc.
  • a section of tube is chosen so that the speed of the water does not exceed 1 to 1.20 m / second.
  • the cold water inlet pipe 6a passes through the wall of the lower curved bottom 1c and is bent twice inside the tank so that a part 6b of said pipe extends substantially in the center of the tank 1.
  • the turns 6a of the exchanger extend parallel to the wall of the shell 1a at a distance relatively close to the latter to reach its upper part.
  • the coil is extended by a hot water outlet pipe 6d, which extends parallel to said curved bottom 1d and crosses it at 7 to extend parallel to the tank 1 but spaced from this until reaching the lower part of the envelope 2 where it passes through the cover 2c of the latter.
  • the part of the tubing 6d, which extends from the wall crossing 7 to the cover 2c of the envelope is placed in an insulating sheath made of a plastic material, felt or any other material and is embedded in the expanded polyurethane 5 while possibly being in contact with the layer of compact insulating felt 4 which envelops the tank 1.
  • the tubing 6d is disposed in a plastic sheath, itself covered with a strip winding distributed over the length of the tubing and consisting of a thermal insulator made of vacuum metallized polyurethane on a layer of polyethylene foam.
  • the tank comprises, at its lower part, a sealed housing, for example cylindrical 8, which opens outside the domed bottom 1c and in which housing is placed an electrical resistance 9 to heat the mass of water contained in the tank and which will be discussed later.
  • This housing is parallel to the longitudinal axis of the tank.
  • This also includes a thermowell 10 which is attached to part 6b of the cold water inlet pipe, which thermowell opens out from the domed bottom 1c and receives the probe 11a from a thermostat. 11 fixed by any known means in a housing 12 located in the lower central part of the casing 2 between the latter and the tank 1.
  • Said housing 12 is closed by a removable hatch 13, for example screwed to the cover 2c of the envelope 2.
  • thermowell 10 is preferably silver brazed longitudinally on the tube part 6b and as close as possible to the arrival of cold water.
  • FIG. 2 partially illustrates the lower part of the balloon according to the invention.
  • the identical parts which have just been described with reference to FIG. 1 have been given the same reference signs.
  • the means for heating the mass of water contained in the tank are constituted by a tubular heater with helical turns 14, the "outward" 14a and “return” pipes 14b of which are connected known manner to a hot water generator, for example a boiler (not shown) whose burner is started by the thermostat 11.
  • a hot water generator for example a boiler (not shown) whose burner is started by the thermostat 11.
  • Said heater 14 is placed for example in place of the electrical resistance 9 and its housing 8.
  • a heat transfer fluid for example water, is circulated in the tubing of the heater 14 in order to heat the mass of water contained in the tank. It comprises a tube 14c extending outside the upper part of the casing 2 and at the end of which is mounted an automatic air vent.
  • the tank 1 further comprises, at its lower part, a cold water filling pipe 15 which opens into the convex bottom 1c, which pipe 15 comprises a tap or a stop valve 16 and, at its upper part, a another expansion pipe 17 of the water contained in the tank, which pipe 17 opens into the convex bottom 1b and extends outside the tank 1 and passes through the cover 2b of the envelope 2.
  • This pipe 17 also includes a stopcock or valve 18.
  • the tank is perfectly sealed and it is therefore unnecessary to equip it with "head plates” or inspection hatches with which the devices currently on the Market are fitted.
  • the upper internal part of the tank 1 can optionally be coated with an anti-rust insulating coating to compensate for the harmful effects of the water vapor created by the heating of the mass of water contained in the tank 1.
  • FIGS. 3 and 4 of the drawing illustrate new means of fixing the balloon according to the invention to a wall wall.
  • first support of a U-shaped profile 19 comprising a part 19a intended to be applied against the wall, which part is pierced with holes 19b for the passage of fixing screws and two wings 19c perpendicular to the part 19a and comprising substantially in their central part a hole 19c1 and a second support 20.
  • Said support 20 is complementary to the first support 19 and like the latter, it comprises a part 20a intended to be applied to the layer of compact felt 4 and two wings 20b which comprise, in their central part, a hole 20b1.
  • Said supports 19/20 can be identical and in this case, after having fixed the support 19 to the wall, the ball is placed by resting the wings 20b of the support 20 on the upper face of the wings 19c of the support 19. Then we assemble the two supports by means of bolts passed through the holes 19c1 / 20b1 reserved in the wings 19c / 20b.
  • said support 20 is applied to the felt layer and the tank and the part 20a of the support 20 are surrounded by circular metallic belts 21, for example two in number.
