Definitions

  • the invention relates to an air recycling system for a room.
  • maintaining a satisfactory level of air quality is essential to ensure the health and comfort of the occupants of the room.
  • the satisfactory level of air quality can however be disturbed by the presence of pollutants resulting from an activity developed inside the premises.
  • fine particles can remain in suspension in the air of the room after the performance of certain manual activities, cleaning, cooking, or even combustion inside the room.
  • the breathing of the occupants of the premises causes the accumulation of bio-effluents, such as CO 2 , in the air of the premises.
  • the satisfactory level of air quality is maintained from a continuous renewal of the air housed in the room as well as its ventilation.
  • a flow of air is extracted from inside the room, in particular from a room thereof provided with a water inlet.
  • the stale air flow is for example extracted by an extraction member.
  • a flow of air, called fresh air is introduced from outside the room into another room of the room, in particular a room having no water inlet through air inlets provided for this purpose.
  • the fresh air flow is generated by a depression created inside the room after the extraction of the stale air flow.
  • the sweeping principle also takes place when the renewal of the air in the room is ensured by blowing.
  • a fresh air flow is blown into the room of the room that does not have a water supply. This blowing creates an overpressure in the room.
  • Stale air outlets provided in rooms equipped with water inlets allow the extraction of the stale air flow.
  • the fresh air flow mixes with the stale air present in the room into which it is introduced, which makes it possible to dilute a concentration of pollutants inside the room.
  • This mixture then continues towards the other rooms of the room through the air passages provided for this purpose (open doors, undercutting of doors, transfer grilles, porosities in the walls, etc.), so as to dilute also a concentration of pollutants inside these other rooms.
  • This principle also implies that the arrival of fresh air in each of the rooms does not depend on the concentration of pollutants in the air of each room. This arrival is notably conditioned by a level of difficulty encountered by the mixture to access each part. For example, when the relief of the doors is insufficient, the mixture will tend to introduce more into the parts for which the door is open. Thus, rooms with a higher concentration of pollutants may be deprived of the arrival of the mixture. Similarly, the flow of stale air arrives in each room depending on the ease of the flow of stale air to pass from the respective room to the extraction member. Therefore, to increase the fresh air in a room, it is necessary to increase the overall extraction rate without being able to target the polluted space.
  • the object of the invention is to remedy these drawbacks.
  • the system according to the present invention it is possible to improve the quality of the air housed in the second room from the introduction therein of the flow of recycled air drawn in from the first room. Also, a decrease in a concentration of pollutants, preferably by dilution, within the second room is possible without bringing in air from outside the room, so as to limit heat loss and energy consumption.

  • the system is configured so that the flow of recycled air sucked in by the return assembly is variable during operation of said system.
  • the system further comprises control means making it possible to activate and/or deactivate the system, and/or to determine an operating mode of the system.

  • the physico-chemical treatment can also be by adsorption, ionization and capture, electrostatic filtration, ozonization, plasma, photocatalysis, biofiltration, use of a disinfectant product or radiation, use of activated carbon, use of UV lamps, etc.
  • the network 15 being able to be connected to several living rooms 4 via the ducts 18, the system 1 according to the present invention makes it possible to carry out centralized processing of several living rooms 4.
  • the system 1 makes it possible to dilute the concentration of the constituent of the air chosen in the living rooms 4 without the need to breathe more fresh air into the room. This therefore makes it possible to limit the concentrations of pollutants while limiting energy consumption and thermal losses. More precisely, the system 1 makes it possible to smooth the level of air pollution of the whole of the room 2, while limiting the energy consumption and the thermal losses.
