  • the components of the cold stage 12 are supported between the base 25 and the cap 26.
  • these components are the evaporator 14, the compressor 15, the expander 16 and the fan 20.
  • Other components may belong to the cold stage 12 such as, for example, an anti-blow bottle 28.
  • the bottle 28 can be placed between the evaporator 14 and the compressor 15 to protect the compressor 15 from a possible fluid inlet. This liquid inlet in the compressor 15 would cause irreversible damage.

  • the cap 26 covers the base 25. It has been seen previously that the water heater 10 may have a substantially cylindrical outer shape . After placing the cap 26 on the base 25, the chamber participates in this cylindrical shape along the axis 23.
  • the components of the cold stage 12 are arranged in an internal volume formed between the base 25 and the cap 26.
  • the two orifices 21 and 22 are formed in the cap 26 to allow the flow of air through the evaporator 14
  • the base 25 is traversed by channels of the thermodynamic circuit in order to reach the condenser 13 disposed in the hot stage 11.

It may be temperature sensors of the heat transfer fluid or of the air passing through the evaporator 14 and of the heat transfer fluid pressure sensors. Cables, not shown on the figure 2 can cross the base 25 to reach a connection box of the water heater 10 for example disposed in the hot stage 11.
  • the enclosure formed by the base 25 and the cap 26, provides an acoustic attenuation of sound waves emitted by the compressor 15.

  • the base 25 and / or the cap 26 are made of a material having larger porosities internally than on the surface.
  • the internal porosity contributes to improving the acoustic attenuation and the reduction of the surface porosity makes it possible to maintain a good seal of the internal air flow in the cold stage 12 relative to the outside.
  • This characteristic can be obtained with certain expanded plastic materials obtained by molding.
  • the expanded structure ensures porosities and the realization in a mold smooths the surface of the mechanical parts thus obtained and thus reduces the porosity of the skin parts.
  • the number of orifices is reduced to the functional requirements of the thermodynamic machine, namely the airflow inlets and outlets for the hot source, the channels of the thermodynamic circuit to the hot stage and the electric cables.
  • the junction between the cap 26 and the base 25 is also adapted to prevent any acoustic leakage. For example, a slightly tight fit can be made between a cylindrical portion 29 made in the base 25 and a bore 30 made in the cap 26. This adjustment also serves to maintain the position of the cap 26 on the base 25 in position.
  • figure 3 represents in perspective the base 25 alone without the components that take place there.
  • figure 4 represents in perspective the cap 26 without component.
  • the base 25 and the cap 26 are single-piece pieces, for example obtained by molding, which makes it possible to produce complex shapes. Other production methods are also possible such as machining.
  • the advantage of the molding is that the cost of producing complex shapes occurs essentially during the production of the mold. In series production, complex shapes are no longer involved except in the case of the necessary drawer in the mold.
  • the definition of the base 25 and the cap 26 can be made to avoid any drawer, or at least to limit the number.
  • the base 25 and the cap 26 comprise forms for accommodating different components of the cold stage 12. These forms open in a common direction, direction carried by the axis 23. In other words, the base 25 and the cap 26 are defined so that their joint plane is perpendicular to the axis 23.
  • the joint plane can of course be broken and include areas inclined relative to a plane strictly perpendicular to the axis 23. Nevertheless the shapes of the base 25 and the cap have sections s' widening towards the joint plane to allow the opening of the molds used only in the direction 23 without additional mechanism to open in a direction distinct from the direction 23 before opening the mold. It is recalled that this type of mechanism is called "drawer" in the field of molding.
  • a shape 31 allows to position the compressor 15.

Firstly, during its operation, the compressor 15 heats up and the air circulating in the zone 40, which makes it possible to cool the compressor 15. Next, the air heated in contact with the compressor 15 circulates in the evaporator 14 which improves the thermal exchange achieved by the evaporator 14. In other words, the heat energy lost by the compressor 15 is recovered by the thermodynamic circuit.

Demolding the base 25 and the cap 26 being effected by a translation movement in a direction carried by the axis 23, the demolding is done without any drawer to achieve the parts 43 and 44.
  • fans can be implemented in the water heater 10. It can for example implement a fan whose air flow follows the same direction in and out. This type of fan is very simple design. On the figure 6 , upstream of the fan 20, the air flow is horizontal axis. The air flow downstream to the fan would then follow the same axis. To limit the pressure losses, the outlet orifice 22 should then have a horizontal axis on the figure 6 or 8 .
