Definitions

  • the present invention relates to a device for heating a fluid for domestic use.
  • the present invention relates to a device for heating water used for personal hygiene and for other domestic activities.
  • the heating device in accordance with the inventive concept of the present invention is connected to a public water supply for domestic use and therefore supplied with drinkable water.
  • the heating device of the present invention is suitable to be connected with another type of water supply, and therefore to be supplied with, and to heat water other than drinkable water generally available in a domestic environment.
  • the state-of-the-art devices for heating water for domestic use are substantially grouped, according to the physical principle used to produce heat for heating water, in electric-type devices (electrical resistance heaters), heat exchange-type devices (air/water heat pumps), and combustion-type devices (natural gas or LPG boilers).
  • electric-type devices electric resistance heaters
  • heat exchange-type devices air/water heat pumps
  • combustion-type devices natural gas or LPG boilers
  • the devices for heating water for domestic use are known to have a configuration that often combines at least two of the physical principles mentioned above, by combining, for example, the air/water heat pump principle with that of the electric heater.
  • the most used state-of-the-art devices for heating water for domestic use are devices that use the heat pump technology to heat domestic water by means of the absorption of thermal energy from the atmospheric air (for convenience, they are also called heat pump water heaters) or from water. Therefore, in technical jargon the heat pump technology is referred to "air/water” type or "water/water” type heat pump technology.
  • the document WO89/06775A1 shows a "water/water”-type heat pump water heater.
  • the document DE3032953A1 shows a heat pump heater even associated to a heating system comprising a traditional boiler.
  • thermodynamic circuit of said device it is possible to define a user fluid that is substantially water (to be heated by the heat pump) for domestic supplies, and an exchange fluid consisting of the atmospheric air and suitable to transfer heat to the water of the domestic supply.
  • the heat pump water heaters comprise a system operating according to a refrigeration cycle, where the repeated phase change of a cooling fluid, such as Freon, allows the absorption of heat from the atmospheric air (the heat absorption being obtained by means of an evaporator) and the transfer of it to the water accumulated within a tank arranged for the connection to a domestic water system (the heat transfer being obtained by means of a capacitor).
  • a cooling fluid such as Freon
  • domestic divalent systems can be realized, operating as a cooling machine to cool water for air conditioning during the summer and as a heat pump for home heating during the winter: the switch from refrigeration machine to heat pump is obtainable by reversing the operation of the evaporator and the condenser.

  • the document WO83/02660A1 shows a heat pump water heater of the "water/water-air" type, which is a further development of the heat pump described above.
  • the evaporation unit of the heat pump is cumbersome and noisy as the fan has to handle rather high air flows in order to effectively warm the refrigerant fluid. It is well known that the evaporation unit of a heat pump water heater plant is separate from the unit including the water storage tank and the condenser, and is installed in an area outside of the dwelling such as, for example, a balcony or a portion of the roof.
  • the aim is to mitigate the noise produced by the fan of the evaporator, however the size generally significant of heat exchanger make the entire evaporation unit aesthetically unpleasant and poorly suited to be integrated with the rest of the home structure, especially when it is a unit installed on an existing construction.
