Definitions

  • Ventilation in the prior art in multi-storied buildings has been maintained with common air supply and exhaust duct systems.
  • the enlarging of ducts is required accordingly which may surpress the dwelling occupancy of the building and at the same time large apparatus for air supply and exhaust have been made necessary.
  • the first object of the present invention proposed for alleviating such defects in the prior art is to control the size of air supply and exhaust duct so that the usuable volume will not be unduly limited.
  • a second object of the present invention is to control the use of air supply and exhaust apparatus to the last extent or not to use them.
  • a third object of the present invention is to provide a system which is not influenced by wind pressure.
  • FIGURE shows an embodiment of the present invention, in which a duct in the ceiling and another under the floor of a closed room, both passing horizontally through the building, are provided.
  • FIGURE shows an embodiment of the present invention, wherein the air supply duct 3 is provided under the floor of the closed room 2 in the building 1, passing through it and the air exhaust duct 4 is provided in the ceiling of the room 2 passing through the building in the same direction as the air supply duct 3.
  • the size of the ducts is the same.
  • the air supply pipe 5 connects the air supply duct 3 with the closed room 2, and the air exhaust pipe 6 connected the air exhaustduct 4 with the room 2. If necessary, a fan may be attached in the air exhaust duct 4 or in the air exhaust pipe 6.
  • a A show the openings of the air supply duct 3, and B B the openings of the air exhaust duct 4.
  • the inside of the closed room 2 is turned into a neutral zone as the air supply duct under the floor and the air exhaust duct in the ceiling of the room 2 are provided.
  • the air When ascending air currents are generated in the closed room 2, the air is exhausted from the air exhaust duct 4 by way of the air exhaust pipe 6 outside of the building 7. Then air which may be equal in quantity to the exhausted air can be supplied from the air supply duct 3 by way of the air supply pipe 5 into the closed room 2. Natural ventilation is performed as mentioned above, but when it is not sufficient, a fan may be placed in the air exhaust duct 4 in order to accelerate ventilation within the room.
  • Embodiment 2 This embodiment is shown in FIG. 2, in which the air exhaust pipe 6 and the air exhaust duct 4 are constructed in the same way as in the embodiment l, but the air supply duct 3 is transformed. That is, the air supply duct 3 is. not constructed independently and only the open parts A A of the duct are constructed on the outside wall at the lower part of the room 2.
  • the open parts B B correspond to the open parts A A.
  • natural ventilation makes the air be exhausted from the air exhaust duct 4 into the outside of the room by way of the air exhaust pipe 6, and the air equal in quantity to the said comes into the room 2 from the open parts A A.
  • a fan may be attached in the air exhaust pipe 6 or in the air exhaust duct 4 in order to accelerate ventilation forcibly if necessary.
  • the air supply duct 3 and the air exhaust duct 4 are constructed in every room of each floor or on one floor for common use, by which ventilation is performed. Therefore, common ducts covering the whole rooms of the building as in the prior art become unnecessary. So, the present invention is excellent in the fact that the dwelling occupancy may not be surpressed since in this inventionthe ceiling and the under floor of the room are used.
  • a system for providing ventilation within a closed room in a building comprising:
  • an air supply duct located beneath the floor of said closed room in a horizontal plane and extending completely through said building and communicating with the surrounding atmosphere;
  • an air exhaust duct located in the ceiling of said closed room in a vertical plane defined by said air supply duct and parallel to said air supply duct and extending completely through said building and communicating with the surrounding atmosphere;
