  • the system according to the invention can, in addition, comprise a box, preferably of substantially parallelepipedal, and a first face of which has an opening opening into the interior space and a second face of which has an opening opening into the second space.
  • the first opening receives the first valve.
  • an air flow is created in the interior space.
  • the air flow created enters the interior space through one of the second and third spaces and comes out through the other of the second and third spaces.
  • the system thus ensures renewal of the air in the interior space.
  • the system makes it possible to synchronize the opening of two valves situated, for example, between a place of residence as an interior space and the atmosphere as a second and third space. More particularly, the two valves can be located in different rooms of the dwelling place so as to create natural ventilation there.
  • the environmental impact of the system is limited because it requires less energy to operate than existing systems, while allowing improved efficiency to be achieved because the ventilation it generates is not only localized at a valve level. , but extends throughout the interior space.
  • the system provides cooling, particularly at night, of the order of a few degrees, for example 5 ° C, compared to the value of the temperature in the interior space in the absence of the system, potentially without creating uncomfortable drafts.
  • place of residence or accommodation is meant a building or part of a building comprising firstly main rooms intended for living or sleeping, possibly isolated bedrooms, secondly service rooms, such as kitchens, bathrooms, laundry rooms. , storage room, dryers, as well as clearances and possibly outbuildings.

  • the second valve 21 constitutes at least part of a window of the dwelling place. More particularly, the second valve 21 can constitute at least part of a roof window or a vertical window in the upper part of a dwelling place as interior space 2.
  • the second valve 21 cooperates with a second control device 22.
  • the latter can be configured to control, optionally alternately or successively, the opening and closing of the second valve 21.
  • the system 1 is therefore advantageously compatible with any existing device for automatically closing and opening the second valve 21.
  • This device can be controlled manually or automatically at least as a function of temperature data and pre-established set points.

  • a relevant algorithm implemented for example by a microcontroller of at least one of the first and second detectors 13, 23, thus makes it possible to manage all the summer and hot inter-season periods without recourse to air conditioning.
  • the system 1 therefore makes it possible to synchronize the opening of two valves 11, 21 located in different places, for example different rooms, of an interior space 2, in particular of a dwelling place, so as to create a natural ventilation. It has the advantage of being inexpensive. As detailed below, its integration, in particular in a place of residence, can easily be carried out so as to ensure its discretion. In particular when it is used according to the aforementioned instructions, the system 1 allows a night cooling of the order of 5 ° C compared to the value of the temperature in interior space 2 in the absence of system 1. The operating objective of system 1 can therefore be the cooling of interior space 2, to avoid summer overheating or to maintain conditions of comfort in intermediate periods. The risk of creating uncomfortable air currents can also be prevented in particular by the choice of rooms in the place of residence where the valves are arranged.
  • the second space 3 comprises one of the atmosphere and an outbuilding, such as a garage or a storeroom, adjoining a dwelling place as the interior space 2 and the third space 4 comprises the atmosphere.

  • the air renewal rate in the interior space is equivalent to twice the volume of interior space 2 per hour if the air flow is due only to convection natural linked to the temperature difference between the indoor temperature and the outdoor environment.
  • the renewal rate can reach up to ten times the volume of the interior space 2 per hour in the event of dynamic stress caused by the effect of the exterior wind.
  • the system 1 comprises a box 100.
  • the box is preferably of substantially parallelepipedal shape, for example rectangle, in particular to facilitate integration and manufacture, but the box can take other shapes such as that of a cylinder , straight or curved, of circular or polygonal section.

  • the box 100 has a length substantially between 70 and 120 cm, a height substantially between 30 and 40 cm and a depth substantially between 10 and 30 cm. Note that these dimensions give the box 100 adaptability above a door unit in the thickness of a wall, for example in rubble stone.
  • the door in question can for example be the one giving from a corridor of the place of residence into the adjoining garage.
  • System 1 thus presents discreet integration so as not to disturb the comfort, in particular visual and acoustic, of the occupants.
  • a visual and acoustic discomfort could indeed be generated by the system 1, in particular when it closes or opens, if it were arranged in a privileged living space, or even vis-à-vis such a space .
  • the first valve 11 can be arranged to open so as to offer the air flow a passage section substantially equal to that offered by the opening of the second valve 12. This ensures efficiency of the renewal of air in the interior space 2, while avoiding creating significant pressure differences at the level of one of the first and second valves by the Venturi effect; this could lead to damage to system 1 or equipment housed in interior space 2.
  • the passage section offered to the air flow by the second valve 21 may be a function of the measured / calculated temperature difference and of one or more several other parameters related to the physical properties of the air in at least one of the interior space 2, the second space 3 and the third space 4.
  • meteorological data which may in particular include, in addition outdoor temperature data: sunshine data, hygrometric data, atmospheric pressure data, wind data, sunset and sunrise data, precipitation data, in more or less places close to the interior space 2.
