Definitions

  • the present invention relates to an indoor air-conditioning unit.
  • the present invention relates to an active chilled beam to which the following description will make explicit reference without however losing in generality.
  • active chilled beams are apparatuses that are usually fixed on the ceiling of the room to be conditioned and are designed to continuously introduce fresh air (i.e. air that has been dehumidified, filtered and conditioned by an air-handling unit that drives and treats external air inside the room), simultaneously heating or cooling the air already present in the room.
  • fresh air i.e. air that has been dehumidified, filtered and conditioned by an air-handling unit that drives and treats external air inside the room
  • the most common active chilled beams on the market basically consist of a large and oblong box-like container, usually rectilinear and having a circular or rectangular cross-section, which extends horizontally close to the ceiling and is adapted to receive a flow of fresh air from an external a Vogellic source; and of an air/liquid heat exchanger which extends adjacent to the box-like container, substantially for the whole length of the container, and is connected to an external hydraulic circuit so as to be continuously crossed by a flow of hot or cold water.
  • the box-like container traditionally called plenum, is provided with a series of small air-outlet holes that are formed on the wall of the box-like container near the heat exchanger so that the air flow coming out from the single holes of the box-like container creates, in the immediate vicinity of the heat exchanger, an additional convective motion that drives the ambient air through the heat exchanger, where it is heated or cooled according to the temperature difference existing between the ambient air and the water circulating in the exchanger.
  • US2002/062948 A1 discloses an active chilled beam wherein the box-like container has a longitudinal recess which has a substantially W-shaped cross-section and accommodates the heat exchanger.
  • the active chilled beams described above have a rather limited use because the pressure drops created in the air flowing inside the box-like container do not allow realizing cold beams with a length over 2-3 meters.
  • the speed of the air flowing out from the individual air-outlet holes of the box-like container in fact, rapidly decreases by increasing the distance to the fresh air inlet in the box-like container, and with it the strength of the additional convective motion driving the ambient air through the heat exchanger.
  • Aim of the present invention is therefore to improve the performance of the active chilled beams described above.
  • an indoor air-conditioning unit as defined in claim 1 and preferably, though not necessarily, in any of the claims dependent on it.
  • the number 1 denotes as a whole an indoor air-conditioning unit that is adapted to continuously add fresh air (i.e. air that has been dehumidified, filtered and conditioned by an air handling unit that drives and treats external air) inside the room to be conditioned, while heating or cooling the air already present inside the room.
