JOHANNE'S PETRUS HEKELAAR ATTOYLNESS United States Patent VENTILATING SYSTEM FOR A BUILDING, E.G. A BUILDING DIVIDED INTO FLATS Johannes Petrus 'Hekelaar, The Hague, Netherlands, as-
signor, by mesne assignments, to N.V. Uutwerp- & Exploitatiebureau Shunt, The Hague, Netherlands, a limited-liability company Application October 24, 1956, Serial No. 618,106
Claims priority, application Netherlands July 4, 1956 1 Claim. (Cl. 98-32) This invention relates to a ventilating system for a building, e.g. a building divided into flats. It has for its purpose to ensure the ventilation of a room and more particularly of rooms on various stories of a building, especially for those cases where the relative room is provided with hermetically closing windows and/or doors. In such a case e.g. in a bath room a situation that is dangerous to the occupant of said room may come into being if no attention is paid to ventilation.
According to the invention the ventilating system comprises two vertical main channels, one of which communicates with the atmosphere at its lower end, the other channel ending at its upper end as a chimney in the atmosphere. A number of rooms of the building that are to be ventilated are connected on the one hand with said first main channel and on the other hand with said second main channel. Thus the rooms are subjected to the natural draught prevailing in the main channel which functions as a chimney.
This system, therefore, is independent of apparatuses [for forced draught and it ensures the ventilation of the relative rooms.
In a practical embodiment of the ventilating system according to the invention one or more rooms of the building to be ventilated may be connected on the one hand to vertical auxiliary channels branched olf from said first main channel. The vertical auxiliary channels end at their upper ends adjacent the floors of said rooms. The rooms on the other hand communicate with the second main channel via auxiliary channels branched off therefrom. Preferably the auxiliary channels in rooms on different stories are arranged in two groups in superposed story-wise relationship. To ensure good ventilation under all conditions it is advisable according to the invention for the vertical distance between the opening through which the first main channel communicates with the at mosphere and the most adjacent opening at the point where an auxiliary channel branches off to be at least 22.00 feet.
In those cases where it is not possible to keep the distance specified, the relative room to be ventilated, instead of being provided with means of a branch from a main channel, is provided with an auxiliary channel which has an opening communicating with the atmosphere.
The invention will be elucidated hereinafter with reference to the accompanying drawing showing an embodiment.
This drawing shows a vertical sectional view of a ventilating system according to the invention, applied to a multi-story building.
In the embodiment chosen the building comprises stories 1, 2, 3, 4 and 5 and a roof. A vertical main channel 7 provides a supply of fresh air shown by arrows 33, 35, 37, 39, 40 to the building 31. An inlet opening 8 which leads to the channel 7 is disposed in a wall 9 somewhere in the lower part of the building, eg in the cellar. The opening 8 ends in the atmosphere. Vertical auxiliary channels 10, 11 and 12 are branched off from the main channel 7. The auxiliary channels 10, 11, 12 feed fresh air as shown by arrows 34, 36, 38 into the rooms located (living quarters, bath rooms, etc.) on the stories 2, 3, '4 through openings 13, 14 and 15. The openings 13, 14, 15 are located at a small distance above the floors of the stories. 2, 3, 4. At its upper end the main channel 7 is provided with an opening 16 which is located at a little distance above the floor of the top most story 5. A further vertical auxiliary channel 17 having an air inlet opening 19 located in the wall 9 communicates with the first story and provides air thereto shown by arrow 32 through an opening 18. Said channel 17 runs parallel to but does not communicate with the lower portion of the main channel 7. The auxiliary channel 17 which, therefore, is not a branch channel, provides for the possibility of causing the vertical distance between the air inlet opening 8 of the main channel 7 and the most adjacent opening 20, that is, the distance where the first vertical auxiliary channel 10 branches from channel 7, to amount to at least 22.00 feet.
A second vertical main channel 21 is provided with auxiliary channels 22, 23 and 24 branching otf therefrom. An outlet 25a serves for the exhaust of air under natural draught. The lower end of said main channel 21 and the lower ends of the auxiliary channels: 22, 23 and 24 are disposed in the upper part of rooms of the stories 1, 2, 3, 4 respectively to be ventilated. The channels 22, 23, 24, 25 are provided with openings 27, 28, 29, 30 which are located near the respective ceilings of stories 3, 4, 5, 6 and through which openings vitiated air shown by arrows 42, 44, 46, 48 is exhausted. In order to enable a sufficient distance to be maintained between the upper portion of the channel 21 and the first communication opening with an auxiliary channel, a still further veitical auxiliary channel 25 is in the form of an independent channel which has its own communication opening to the atmosphere.
I claim:
