Description

[0001] DOOR COMPRISING A FAN COIL DEVICE

[0002] DESCRIPTION

[0003] Field of the invention

[0004] The invention falls within the sector relating to the air-conditioning of indoor environments. In particular 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.

[0005] Prior art

[0006] During the course of the last 50 years, radiant floor heating systems have enjoyed an upsurge of popularity and been further developed such that they have gradually become the system which is most widely used. During at least the last decade there has been the tendency to combine this heating system (which has now become conventional) with a reversible application where this system can also be used in the summer for cooling purposes. In this latter case the operation of the cooling floor during the summertime must be necessarily combined with an air dehumidification plant in order to be able to ensure suitable comfort from a thermo-hygrometric point of view.

[0007] The advantages of employing this type of heating and cooling system compared to other systems have thus become well-known, but much less so the disadvantages which are associated with this system.

[0008] During the last few decades, the energy policies adopted on an international level have defined various priorities, including incentives to develop and use renewable energy, greater energy efficiency in buildings, and reduced consumption levels. As a result, the sensitivity regarding environmental issues has increased, building constructions have undergone changes, and heat calculation methods have been adapted.

[0009] It has therefore been possible to note a significant reduction in the winter heating requirements of buildings (a decrease of more than 50%) owing to the reduction in the heat transmission coefficients of constructional elements (roofs, flooring, ceilings, walls, windows, etc.) and also climate change. This latter aspect, since an increase of 2.5°C in the average annual temperature has been recorded during the last 50 years, has helped further reduce the winter heating demand (-10%), although there has been an increase by a similar percentage amount in the summertime cooling demand. It therefore seems likely that the buildings of the future will require an increasingly greater amount of power for summer cooling and increasingly less power for winter heating.

[0010] Architectural design has also undergone a significant change during the last 30 years, initially favouring increasingly more luminous internal environments and facilitating the entry of natural light from the outside through windows and glass structures with increasingly larger dimensions. This tendency in the architectural sector has favoured, in addition to the entry of a greater amount of natural light, also the entry of heat due to solar radiation (during both the summer and winter), thereby increasing the thermal inertia of materials such that they accumulate heat in a given moment and then release into an environment in thermal contact with these materials.

[0011] EP 0 860 663 A2, FR 3 061 267 A1 , FR 2 592 915 A1 and FR 2 085 473 A1 belong to the prior art.

[0012] In the light of the above, in the interior design sector it would be desirable to provide new heating and / or cooling systems which are characterized by a low impact from an aesthetic point of view and by small dimensions.

[0013] The Applicant, after a long and in-depth R&D investigation work, has developed a door and an architectural construction which are able to provide a suitable response to the existing limitations, drawbacks and problems.

[0014] Summary of the invention

[0015] The object of the invention is to overcome the aforementioned drawbacks of the prior art.

[0016] The present invention therefore relates to a door 100 comprising:

[0017] - a door frame 25, which circumscribes a frame opening 26;

[0018] - 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 ;

[0019] - a fan coil device 50, comprising at least, housed in the containment compartment 30:

[0020] (a) at least one heat exchanger unit 12, 13;

[0021] (b) 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 ;

[0022] (c) optionally at least one air filter 15 for filtering the air stream between the first opening 32 and the heat exchanger unit 12, 13; wherein said first opening 32 and said second opening 31 are arranged and / or oriented so that said air stream is drawn in and blown out from the front of the same outer surface 27; 28.

[0023] The present invention also relates to an architectural construction 200 which comprises:

[0024] - 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 ;

[0025] - a fan coil device 50, comprising at least, housed in the containment compartment 30:

[0026] (a) at least one heat exchanger unit 12, 13;

[0027] (b) 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 ;

[0028] (c) optionally at least one air filter 15 for filtering the air stream between the first opening 32 and the heat exchanger unit 12, 13; wherein a finish of at least one outer surface 27; 28 overlapping the containment compartment is the same as a finish of one or more second surfaces 39 which surround or flank the containment compartment 30.

[0029] Advantages of the invention

[0030] The invention has the advantages described below.

[0031] Advantageously, 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.

[0032] Advantageously, 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. Advantageously, 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.

[0033] Advantageously, the sound-absorbing baffles are able to convert part of the incident sound energy - by means of the air stream - into heat.

[0034] Advantageously, 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.

[0035] Advantageously, 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.

[0036] Advantageously, the door or architectural construction according to the present invention allows easy maintenance also of the components inside the containment compartment.

[0037] Advantageously, 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). Although 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.

[0038] Commercially available 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.

[0039] Advantageously, the structure of the door leaf or the wall allows the aesthetic appearance to be personalized with greater design freedom.

[0040] Additionally, 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.

[0041] Advantageously, 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.

[0042] Advantageously, 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.

[0043] Advantageously, 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. As a result of 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.

[0044] Advantageously, 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.

[0045] Advantageously, 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.

[0046] Advantageously, the fan coil device used in the door or architectural construction according to the present invention occupies a very small amount of space in the vertical direction.

[0093] Detailed description of a preferred embodiment of a door according to the invention

[0094] Fig. 1 shows a door 1 which comprises a door frame 25 and at least one door leaf 2. The door frame 25 circumscribes a frame opening 26 visible in Fig. 3 and Fig. 4. The door leaf 2 is shown in a position where it overlaps the frame opening 26 and is mounted on the door frame 25 so as to be rotatable about a rotation axis 49, by means of hinges 35, from the overlapping position into an offset position. In the offset position, the door leaf 2 is at least partially rotated about the rotation axis 49 with respect to the position of Fig. 1 so that the frame opening 26 is partially accessible.

[0095] The door leaf 2 comprises outer surfaces 27, 28 separated by a thickness 29 of said door leaf 2. A removable panel 37 could delimit least at least part of one of the outer surfaces 27, 28, said removable panel 37 being fixed to an inner frame 3 of the door leaf 2.

[0096] The door leaf 2 comprises an optional closing device (for example a lock) for securing the door leaf 2 to the door frame 25, and a handle 42 for operating the closing device. The handle 42 is mounted projecting from at least one outer surface 27, 28.

[0097] In the overlapping position, the door leaf 2 and the door frame 25 jointly delimit at least one open passage or space 1 for an air stream entering and leaving the door leaf 2.

[0098] Fig. 2 shows a longitudinal section through the door 100 of Fig. 1.

[0099] A containment compartment 30 is circumscribed between the outer surfaces 27, 28, and this compartment 30 houses at least part of a fan coil device 50, in particular at least one heat exchanger unit 12, 13 and ventilation means 33 of said fan coil device 50.

[0100] The fan coil device 50 comprises a heating unit 12 and a cooling unit 13 connected, respectively, to a heating plant (for example comprising a boiler) and a cooling plant (for example comprising a refrigeration device).

[0101] Said connection is performed by means of hydraulic lines 22, 23 configured to convey a heat-transfer fluid cooled by the cooling plant to the cooling unit 13 and to convey a heat-transfer fluid heated by the heating plant to the heating unit 12. These hydraulic lines 22, 23 are configured to then convey said fluids back from the units 12, 13 to the respective plants after a heat exchange with the air stream has been performed. The hydraulic lines 22, 23 therefore extend outside of the containment compartment 30, passing through the door frame 25, and are at least partially housed in the support wall 47.

[0102] The hydraulic lines 22, 23 comprise flexible tubes 20 which are designed to follow the movement of the door leaf 2 from the overlapping position into the offset position, and vice versa.

[0103] The ventilation means 33 comprises a motor 11 and a tangential or centrifugal fan 5, the latter being keyed onto a drive shaft of said motor 11 . The motor 11 is supported inside the containment compartment 30 by a motor support bracket 9 fixed to the inner frame 3, said bracket 9 being provided with rolling means 10 (for example one or more bearings) for the drive shaft. The ventilation means also comprise a baffle 6 for the air stream associated with the tangential fan 5.

[0104] The door leaf 2 delimits at least one first opening 32 and at least one second opening 31 which are in fluid communication with the containment compartment 30.

[0105] The first opening 32 and the second opening 31 are arranged and / or oriented so that the air stream is drawn in and blown out from the front of the same outer surface 27; 28. In other words, the air stream does not cross completely the thickness 29 of the door leaf 2.

[0106] More precisely, the first opening 32 and the second opening 31 are arranged on connecting surfaces 34, 36 which extend between the outer surfaces 27, 28 along the thickness 29. Furthermore, the first opening 32 and the second opening 31 are in fluid communication with the open passage 1 .

[0107] The door leaf 2 comprises - housed in the containment compartment 30 - first curved or straight baffles 16 in a position between the first opening 32 and the heat exchanger unit 12, 13 and second straight baffles 4 between the heat exchanger unit 12, 13 and the second opening 31.

[0108] The containment compartment 30 has, housed inside it, also an air filter 15, configured to retain dust and / or particles suspended in the air stream, and at least one condensate collection container 14, 21 of the fan coil device 50, said condensate collection container 14, 21 being located vertically underneath the cooling unit 13. The condensate collection container 14, 21 is connected (or can be connected) to a hydraulic line 24 for discharging the condensate.

[0109] The door 100 comprises at least one power supply line 19 for the ventilation means 33 and optional management and control means 7 of the fan coil device 50. The management and control means 7 comprise a user interface situated along a longitudinal connecting surface 34 of the door leaf 2, more preferably the longitudinal connecting surface 34 opposite the hinges 35.

[0110] The power supply line 19 and the hydraulic line 24 for discharging the condensate also comprise flexible tubes or cables for following the movement of the door leaf 2.

[0111] The ventilation means 33 are 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 .

[0112] More precisely, the air stream is drawn in through the open passage 1 situated laterally and the first opening 32, is deviated by the first curved baffles 16 towards the air filter 15, and is then conveyed so to exchange heat with the heat exchanger unit 12, 13.

[0113] If the air stream must be heated, a quantity of heat is transferred from the heated heat-transfer fluid to the air stream exiting the air filter 15.

[0114] If the air stream must be cooled, a quantity of heat is transferred from the air stream exiting the air filter 15 to the cooled heat-transfer fluid 15. During cooling, dehumidification of the air stream also occurs, so that a condensate is deposited on the cooling unit 13 and is then collected in the condensate collection container 14, 21 .

[0115] After the heat exchange in the heat exchanger unit 12, 13, the air stream reaches the tangential fan 5 from where it is then forced along the second straight baffles 4 and, from there, it is blown out from the second opening 31 and from the open passage 1 located above it.

[0116] Fig. 3 and Fig. 4 show, respectively, a horizontal cross-section and a vertical cross-section through the door of Fig. 1 in which the construction of the door frame 25 - among other things - is visible.

[0117] The door frame 25 comprises a frame member 43 which is / can be connected to a counter-frame 44, and at least one covering element 45 which overlaps at least partly on the frame member 43 so as to cover an intermediate space between the frame member 43 and the counter-frame 44.
