Definitions

  • the invention relates to convectors intended for air conditioning of premises and, in particular, domestic premises, such as those used in private apartments.
  • FIG. 1 shows a type of convectors known by the French patent FR-A-2 726 636.
  • a type of convector 1 is fixed on a wall 3. It has a convection chamber 10 comprising a front compartment 11 and a compartment rear 12.
  • Air inlet 21 is located at base 20 of convector 1 in the form of a grid 22.
  • the ambient air in the room therefore enters through air inlet 20, goes up, a once heated, in the rear compartment 12 and arrives in the upper part 14 of the convection chamber 10.
  • the upper wall 42 returns the heated air to the front compartment 11.
  • An air outlet 31 is provided in a front wall 30, rather in its lower part. Fins 33 inclined towards the low can equip this air outlet 31 to send the heat down the room. We note that this air outlet 31 is slightly higher than the inlet air 21.
  • the object of the invention is to propose a device enabling hot air to be produced, or cold air, in any room, without bring noise pollution.
  • the front wall of the housing is formed of a material which is a good conductor of the heat, while the rear wall of the housing is a thermally insulating wall.
  • the wall rear of the housing has a metal plate separated from the rear compartment of the convection by a thermally insulating layer.
  • the wall of the housing is thermally insulating and has a metal plate which is separate from the convection chamber by a thermal layer insulating.
  • the side walls of the housing have each a portion which laterally delimits the rear compartment of the convection chamber, at minus that portion of each side wall being thermally insulating and comprising a plate metallic which is separated from the convection chamber by a thermally insulating layer, at least in the portion of the side wall which delimits laterally the rear compartment of the convection chamber.
  • the air outlet of the convector comprises fins inclined downwards, from rear to the front, to direct the air which is slanting downwards comes out of the convection chamber.
  • the hot source is a electrical source.
  • the cold source is preferably produced by a finned exchange battery and powered by a source of chilled water.
  • Hot and cold sources can be powered by a single reversible heat pump placed elsewhere than where the convector.
  • means are used shutter in the front compartment of the room convection to prevent the air from going up in the upper part of the latter.
  • a profile as a cover placed above a partition separating the front compartment and rear compartment, shaped curved and being fixed on a rear wall of the convector to force hot air from the rear compartment to head towards the compartment before.
  • the convection chamber 50 is always divided into a compartment before 51 and a rear compartment 52 by a partition substantially vertical 53 which is insulating.
  • a first entry 61 ambient air is placed at the base 60 of the convector. It is preferably fitted with a grid 62.
  • the hot spring 55 can be an electrical resistance located at this level of grid 62, or be an element any heater placed a little higher, like is the heating element 2 of figure 1.
  • the part top of the convector is fitted with a plate metal 64 placed on the outside of the convector and which is separate from the convection 50 by a thermally insulating layer 65. This constitutes the upper wall 93 of the convector.
  • the front wall 70 is formed of a good heat conductive material so that a part of the heat provided by the hot air coming from rear compartment 52 heats this front wall 70 so that the latter shines in the room.
  • a rear wall 90 is provided and is composed of a metal plate 91 separate from the rear compartment 52 of the convection chamber 50 by a thermally insulating layer 92.
  • the walls side are constructed from the same way.
  • a front wall 70 fitted in its lower part with an air outlet 71, possibly fitted with fins 73 inclined towards the bottom.
  • the cold source according to the invention is placed in a second air inlet 100 of the convector located in the upper part of the rear wall 90 of the convector. It opens into the upper part 54 of the convection chamber 50.
  • a cover profile 104 is provided constituting an awning, placed inside the convection chamber 50, just above the partition insulating 53, fixed on the thermally insulating layer 92. With its curved downward shape, it thus allows with hot air coming out of the rear compartment 52 of the convection chamber 50 to be returned directly to the front compartment 51 thereof, in the direction of the air outlet 71.
  • a means shutter 105 to prevent hot air from rising in the upper part 54 of the convection chamber 50.
  • These sealing means may be made up a shutter valve.
  • the cold source can be produced under the shape of a classic finned battery powered by a chilled water circuit.
  • a feature of this cold source is that it has a slight loss of charges for air coming from outside, i.e. from behind the convector and heading towards the upper part 54 of the convection chamber 50. This facilitates the organization of the exit from air, even hot, through the air outlet 71 which is rather towards the bottom of the convection chamber 50, at the instead of going up and out through the cold source 101.
  • the hot source 55 can be supplied with electrical energy through the distribution network electricity.
  • the cold water source 101 can be supplied with chilled water by a heat pump placed in a place by necessarily close to where the convector is placed.
  • a single heat pump 110 can supply water cold for cold source 101 and hot water for the hot spring 55.
  • Control means 120 are provided to operate either one or the other of these sources 110 and 111, depending on the temperature prevailing in the room where the convector.
