Definitions

  • Another reason for the decrease in efficiency is due to the masses of hot air which have not followed the normal path of the air circuit clogging the fan without having stored or given up the number of calories expected.
  • Rigorous sealing in the part of the vacuum circuit eliminates any re-entry of fresh air into the device and, since it operates at constant air mass, also prevents any leakage of hot air to the outside from the rest of the air circuit which can then be built more simply to install an insulating barrier against leakage currents.
  • the claimed invention overcomes the aforementioned drawbacks by means of constructive arrangements making it possible to obtain sealing in the part of the air circuit under vacuum and to design the rest of the air circuit to allow effective insulation.
  • Figure 1 shows a base 1, of parallelepiped shape, made of very thick sheet metal, ribbed to increase its stiffness and surmounted by a series of support pieces 2 intended to take up the load of the core.
  • a thermal insulation 3 placed in a metal tray 4 to protect the insulation 3 against humidity of the laying surface.
  • Behind solcle 1 is another element called rear plinth 9, the upper face of which is open and which is fitted inside two deflectors 10 and 11 to distribute the air streams at the inlet of plinth 1 well.
  • the base 1, the front-base 5 and the rear-base 9 constitute a box 12 into which slides, like a drawer, a set of elements presented in Figures 1b and 1c.
  • the central element of the box 12, namely the base 1 has at the base a stall relative to the front-base 5 and to the rear-base 9 for positioning the insulation 3 and its protective tank 4.
  • the thickness of the insulation has been chosen so that only the base 1 is supported on the ground. This arrangement guarantees the resumption of all the load by the only base 1 and this, even in the event of a slight subsidence of the ground under the weight of the device.
  • the deflector cone 14 matches at one end the rectangular outline of the heat exchanger 13 and at the other end it has a circular section bearing on the circular hole 26 of the bottom plate 25 and opening out inside the ventilation volute 15 by a flared rim 27.
  • the end of the ventilation volute 15 carries two wings 28 which slide into the slides 8 of the casing 12.
  • the heat exchanger 13 is provided with two connection pipes 29 and 30 to the outdoor heating circuit.
  • the insulating closure plate 31 is fixed on the fixing flanges 21 and 22 of the bottom plate 25 so as to present the hole 36 of the fan wheel 35 in the center of the flared circular flange 27 of the deflection cone 14.
  • the rear pedestal 9 carries two lateral tabs 39 and a rear tab 40 for supporting an insulating seal 41 shaped so as not to obstruct the air streams moving towards the upper face of the rear pedestal 9.
  • Figure 2 shows all of the metal elements arranged around the storage core, not shown in this figure, and resting on the box 12 with interposition of thermal insulators 38 and 41 respectively for the front base 5 and the rear base 9 and for the base 1 an insulator 42 and 42 ′ distributed in two panels, on either side of an angle iron 43 serving to support the lateral thermal insulation not shown.
  • Two side plates 44 and 45 folded down towards the interior of the device rest on the insulating panel 42 'and are held in place by the weight of the accumulator core.
  • Front-base 5 side, these side plates 44 and 45 receive a chimney front 46 and rear pedestal side 9, a rear chimney 47.
  • the front chimney 46 has the general shape of a rectangular parallelepiped open on its entire upper face and carrying on its lower face an opening 48 aligning with the opening 7 of the front base 5.
  • the inner face of the front chimney 46 is pierced with holes 49 allowing the air conveyed by the motor-fan unit to enter the channels of the accumulator core, not shown.
  • This insulating barrier 59 prevents any propagation of the leakage currents, generated by the heating elements 61 brought to high temperature, towards the box 12. Given the star supply of the heating elements 61, the superstructure 58 and the core 60 constitute a free neutral point, while the outer casing 62, the casing 12 and the module 18 are earthed.
