Definitions

  • the first air inlet of the centralization device is configured to be connected to a first extraction vent arranged in the first room.
  • the second air inlet of the centralization device is configured to be connected to a second extraction vent arranged in the second room.
  • the single-flow ventilation system 10 may comprise at least one sensor 36 configured to measure a significant magnitude of a ventilation requirement.
  • the at least one sensor 36 may be a CO2 and/or humidity and/or VOC and/or temperature sensor.
  • the at least one sensor 36 may be arranged in the extraction flow centralization device 18.
  • the at least one sensor 36 may be remote from the extraction flow centralization device 18.
  • the pressure measuring means may comprise a pressure sensor.
  • the pressure sensor may be configured to be placed in communication with the air internal to the extraction flow centralization device 18.
  • the pressure sensor may be arranged in the extraction flow centralization device 18.
  • the first regulating means 28 and/or the second regulating means 30 may comprise a closing means 46, such as a shutter.
  • the single-flow ventilation system 10 may comprise the first extraction vent 12 configured to be arranged in the first room 102.
  • the single-flow ventilation system 10 may comprise the second extraction vent 14 configured to be arranged in the second room 104.
  • the first extraction vent 12 may be connected to the first air inlet 20 of the extraction flow centralization device 18 by a first inlet duct 40.
  • the second extraction vent 14 may be connected to the second air inlet 22 of the extraction flow centralization device 18 by a second inlet duct 42.
  • the second part 104 may be a so-called main part, that is to say comprising an air inlet opening 106 configured to connect an air flow external to the main part and an air flow internal to the main part.
  • the air inlet opening 106 allows a movement of air from the outside to the inside of the main room, thanks to a depression created by the fan 16, via the air extraction vents.
  • the air inlet opening 106 may be a non-motorized ventilation means.
  • the first room 102 may be a so-called technical room, i.e. one without an air inlet opening.
  • the premises 100 may comprise a plurality of technical rooms.
  • the first part 102 and the second part 104 may be main parts. Alternatively, the first part 102 and the second part 104 may be technical parts. Alternatively, the first part 102 may be a technical part and the second part 104 a main part.
  • the operating conditions of the ventilation system can be influenced by so-called disruptive phenomena, such as the presence of air leaks in the premises, wind outside the premises, or a temperature difference between the interior of the premises and the exterior of the premises.
  • disruptive phenomena such as the presence of air leaks in the premises, wind outside the premises, or a temperature difference between the interior of the premises and the exterior of the premises.
  • the total air extracted by the extraction vents is generally distributed in proportion to the air inlet openings in the main rooms.
  • the air flow extracted by the extraction vents corresponds to the sum of the air flows circulating at each air inlet opening of the main rooms.
  • Air intake openings located on windward facades are favored, while air intake openings located on other facades are disadvantaged, i.e. the airflow circulating at the windward facades is greater than the airflow circulating at the other facades. Indeed, the overpressure generated on the windward facades adds to the depression generated by the fan. Conversely, the depression generated on the other facades opposes the depression generated by the fan. Some main rooms may therefore be disadvantaged and the efficiency of the ventilation system is reduced in these rooms.
  • a thermal draft regime is established: the cold outside air is heavier than the hot inside air and a parasitic air flow is established from the air intake openings and/or leaks located in the main rooms on the ground floor, towards the air intake openings located in the main rooms on the upper floors.
  • a thermal draft regime can go as far as cancelling all air passage at the level of the main rooms located on the upper floors, or even to a reversed air passage, with an air flow from the inside to the outside of the dwelling in extreme cases.
  • the efficiency of the ventilation system is reduced.
  • the ventilation system makes it possible to ignore disturbing phenomena such as the presence of air leaks in the premises, wind outside the premises, or a temperature difference between the interior of the premises and the exterior of the premises. Indeed, the ventilation system makes it possible to modulate the extraction flow rate in the main room according to information from a thermal environment identical or close to that of the main room.
  • the single-flow ventilation system 10 is configured to allow the ventilation of premises 100 further comprising a third room 105.
  • the third room 105 may comprise a third extraction vent 15.
  • the fan 16 can be connected to the first 12, second 14 and third 15 extraction vents to perform air extraction in the first 102, second 104 and third 105 rooms.
  • the single-flow ventilation system 10 may further comprise the third extraction vent 15 configured to be arranged in the third room 105.
  • the third extraction vent 15 may be connected to the fan 16 by a second outlet duct 44.
  • the single-flow ventilation system 10 may comprise the second outlet duct 44 configured to connect the third extraction vent 15 to the fan 16.
  • the first room 102 and the second room 104 may be main rooms, i.e. each comprising an air inlet opening 106 configured to connect an air flow external to the main room and an air flow internal to the main room.
  • the third room 105 may be a technical room, i.e. without an air inlet opening.
  • the third room 105 may comprise a third extraction vent 15.
  • the extraction flow centralization device 18 may comprise a housing 45.
  • the housing 45 may be in two parts configured to cooperate together, for example by complementarity of shape, so as to be able to access the internal elements of the housing 45.
  • the sensor 36 may be arranged in the housing 45.
  • the first sensor and/or the second sensor may be arranged in the housing 45.
  • the at least one sensor 36 may be arranged in the housing 45.
  • the air sampling means 33 may be at least partly arranged in the housing 45.

  • a third extraction vent configured to be arranged in a third room of the premises, may be connected to the extraction flow centralization device 18, for example via a third inlet duct 43.
  • the extraction flow centralization device 18 may comprise a third means 31 for regulating the air flow circulating in the third air inlet 23.
  • the third regulating means 31 may be a valve for managing an air flow, circulating in the third air inlet 23.
  • the third regulating means 31 may comprise a closing means 46, such as a shutter.
  • the third regulating means 31 can be arranged in the third air inlet 23 of the extraction flow centralization device 18.
  • the control device 34 can be configured to further control the third regulating means 31 of the air flow circulating in the third air inlet 23 according to information communicated by the air measuring means 32.
  • the sensor 36 can be arranged downstream of the first outlet orifice 4, relative to the direction of circulation of the flow circulating from the inlet orifice connected to the first outlet orifice 4, towards the first outlet orifice 4.
  • a single sensor 36 can be used for several rooms of the premises 100, so that the number of sensors 36 per ventilation system 10 is reduced. This makes it possible to reduce the costs associated with the sensors, but also to facilitate the installation of the sensors in the ventilation systems, as well as their maintenance.
