Definitions

  • the invention falls within the sector relating to the air-conditioning of indoor environments.
  • the present invention relates to a door or an architectural construction comprising a fan coil device at least partially (for example, completely) incorporated inside it.
  • EP 1 441 184 A1 , DE 10 2007 055245 A1 and FR 3 061 267 A1 belong to the prior art.
  • the object of the invention is to overcome the aforementioned drawbacks of the prior art.
  • the present invention therefore relates to a door 100 comprising:
  • At least one door leaf 2 which is movable with respect to said door frame 25 between a position where it overlaps the frame opening 26 and a position where it is offset with respect to said frame opening 26; wherein said door leaf 2 comprises opposite outer surfaces 27, 28 separated by a thickness 29 of said door leaf 2, said outer surfaces 27, 28 circumscribing between them a containment compartment 30, and wherein said door leaf 2 delimits at least one first opening 32 and at least one second opening 31 ;
  • a fan coil device 50 comprising at least, housed in the containment compartment 30:
  • ventilation means 33 configured to draw in an air stream through the first opening 32, to move said air stream so that it exchanges heat with the heat exchanger unit 12, 13, and to then blow out said air stream from the second opening 31 ;
  • the present invention also relates to an architectural construction 200 which comprises: a building wall 40 comprising opposite outer surfaces 27’, 28’ separated by a thickness of said building wall 40, said outer surfaces 27’, 28’ circumscribing between them a containment compartment 30, and wherein said building wall 40 delimits at least one first opening 32 and at least one second opening 31 ;
  • a fan coil device 50 comprising at least, housed in the containment compartment 30:
  • ventilation means 33 configured to draw in an air stream through the first opening 32, to move said air stream so that it exchanges heat with the heat exchanger unit 12, 13, and to then blow out said air stream from the second opening 31 ;
  • the invention has the advantages described below.
  • the door according to the present invention performs the functions of a door and of a fan coil for environments so as to produce, heating, cooling and/or dehumidification.
  • the door according to the present invention comprises a door leaf which is substantially indistinguishable (in terms of dimensions, functionality and appearance) from a conventional door leaf.
  • This advantage is even more evident in the case of embodiments where the outer surfaces are devoid of openings for the passage of the air stream.
  • the door or architectural construction according to the present invention ensures a high degree of acoustic comfort, not only as a result of the ventilation means and the baffles described here.
  • the architectural construction according to the present invention has been designed to avoid stratification of hot air at the top and cold air at the bottom and to reduce any disturbance caused by cold air streams.
  • the sound-absorbing baffles are able to convert part of the incident sound energy - by means of the air stream - into heat.
  • the presence of special hinges allows the movement of the door leaf to be controlled, for example so as to prevent accidental collisions or avoid excessive pulling or compression of the lines.
  • the internal components of the door or the architectural construction according to the present invention may be selected or provided with dimensions as desired according to the specific requirements, for example depending on a required thermal or refrigerating power demand.
  • the door or architectural construction according to the present invention allows easy maintenance also of the components inside the containment compartment.
  • the door or architectural construction according to the present invention offers the major advantage that it occupies only the space needed and does not negatively affect the overall appearance of the surrounding environment (i.e. an advantage not only in aesthetic terms).
  • small-size fan coil units are now commercially available, the space they occupy is still considerable and therefore constitutes a design (i.e. ultimately physical) problem within an environment.
  • dehumidifiers of the ducted type specific for radiant flooring to be mounted in the lowered ceiling require at least a net working height of not less than 25 cm, plus another 5 cm downwards for the thickness of the support structure. This results in a significant reduction in the internal height and volume which the environment loses. Also the installation of the complete radiant flooring assembly requires a greater thickness of at least 6-8 cm heightwise, which needs to be taken into account during the architectural design stage. Also, in the case of dehumidifiers of the visible wall-mounted type, their significant size constitutes an obstacle when they must be installed on an internal wall, occupying a portion thereof. This also constitutes a disadvantage from a cost point of view.
  • the structure of the door leaf or the wall allows the aesthetic appearance to be personalized with greater design freedom.
  • the door or architectural construction according to the present invention also offers economic advantages due to lower installation costs compared to ceiling-mounted fan coil units, resulting in saved space, even heightwise, within an environment.
  • the door or architectural construction according to the present invention ensures a greater responsiveness and thermal efficiency, since the heat-transfer process occurs by means of convection, allowing the desired temperatures to be reached more quickly compared to a radiant floor heating and cooling system.
  • the architectural construction according to the present invention has been designed in order to reduce or eliminate the risk of mixing between the air sucked in (for example along a floor) and the air blown out (for example along a ceiling). Owing to the considerable distance between the air stream which is sucked in at the bottom and the air stream blown out at the top, any risk of the air stream which is blown out from being sucked back together with the sucked-in air stream, without passing uniformly throughout the environment, is reduced or total eliminated, thus ensuring that the air in the environment is completely treated.
  • the evacuation of condensate released from the air passing over the cooling unit in the door or architectural construction according to the present invention results in a self-cleaning function of the cooling unit.
  • the door or architectural construction according to the present invention allows the evacuation of the condensate released from the air passing over the cooling unit.
  • this feature it is possible to achieve low surface temperatures on the heat exchanger unit and dehumidification of the air passing over the unit. This results in drier air, improved breathing (more oxygen and less water vapour in the air), more natural sweating (dissipation of latent heat), and a perception of fresher air in the installation environment.
  • the door or architectural construction according to the present invention has a greater acoustic efficiency and lower head losses (energy dissipation) of the air flowing through it, due to the sound-absorbing means described here.
  • Reduced head losses lead to a favourable decrease in the electrical energy requirement/consumption of the ventilation systems.
  • the door or architectural construction according to the present invention has a compartmentalized internal compartment so that the air stream passes outside the space housing the electrical components. This results in greater safety and increased convenience during potential maintenance operations.
  • the fan coil device used in the door or architectural construction according to the present invention occupies a very small amount of space in a vertical direction.
