Description

Iy[ANIFOLD WITH TWO-DIMENSIONAL AND THREE-DIMENSIONAL CONFIGURABILITY, IN SO FAR AS IT IS EQUIPPED WITH ROTATING CONNECTIONS, FOR CEILING-MOUNTED AND/OR WALL- MOUNTED THERMAL-CONDITIONING SYSTEMS
*****
The present invention substantially relates to a manifold, in particular for ceiling-mounted and/or wall-mounted thermal-conditioning systems, which is altogether innovative in that it is equipped with swivel pipe fittings that enable connections to be made both in a plane and in space.
Ceiling-mounted and wall-mounted thermal- conditioning systems have been devised and developed only fairly recently and are built by assembling together modular panels, which are equipped with a coil in which the thermal-conditioning fluid flows and which can be connected to one another via a plurality of manifolds. The sizing envisages mounting of the modules on the walls and/or on the ceilings of a dwelling, converting the surfaces that normally allow the cold to enter in winter and the heat to enter in summer into radiant surfaces of the air-conditioning system. The major advantage of these thermal-conditioning systems is that of functioning as thermal barrier towards the outside, and consequently their adoption enables a large number of problems to be solved, above all when restructuring. A widespread application of a modular type is constituted by radiant panels made of fire- repellent plasterboard, ' which, being applied either ceiling-mounted or wall-mounted, afford the possibility of regulating and obtaining an ideal temperature and an optimal thermal comfort in the different environments of the dwelling in all the periods of the year, recreating the same climatic conditions of well-being that are achieved, of course, without the aid of any air-conditioning system, above all in the milder seasons of the year, i.e., autumn and spring.
Said thermal-conditioning systems exploit the- principle of irradiation of heat and, as compared to traditional thermal-convection systems, guarantee greater efficiency, lower running costs, as well as optimal thermal comfort. In fact, the human body- favours the exchange of heat by irradiation over exchange of heat by thermal convection and thermal conduction. The majority of traditional heating systems, instead, use exchange by thermal convection, heating above all the air that surrounds us, frequently dehumidifying it excessively, thus increasing the circulation of dust. Since systems made with radiant panels do not involve air, they do not raise dust, and above all do not render the environment excessively dry, thus enabling reduction of the temperature of the ambient air even by 2°-3°C with an equivalent degree of comfort and functioning at low running temperatures of the heating fluid (30°-50°C in winter and 15°-20°C in summer) , thus enabling a saving of up to 40-50% of the consumption of electricity, with very high unit yields of up to 150-200 W/m2. Ceilings with radiant modular panels have recently found application not only in residential environments but also in offices and hotel and hospital structures.
Inserted within the radiant modular panels is a network of pipes or a tubular coil, in which the thermal-conditioning fluid flows. The radiant panels can be applied directly to the rough ceilings, by means of spacing bars and brackets and then plastered, or else pre-assembled and fixed on false-ceiling structures.
Said network of pipes or coil present in each radiant panel is connected to the other networks of pipes or coils present in the other radiant panels, to be mounted adjacent thereto, via a plurality of manifolds with two or more ways in order to create a single thermal-conditioning circuit. Current manifolds of recent production are made of plastic material and are shaped so as to guarantee insertion of the pipe of the panels.
The distributors of the manifold are frequently- provided with anticondensate shells, as well as fast- coupling connectors for the connection of pipes usually having dimensions that range between 6 mm and 20 mm in diameter.
The ' main disadvantage of current manifolds for radiant panels is represented by the fact that they are not flexible, but rather are rigid, and hence during installation do not enable a convenient mutual constraint of the pipes leaving the radiant panels to the manifolds themselves, with consequent disadvantages owing to the difficulty of installation and consequent times required for making them. In addition, there remains the further uncertainty of providing an effective connection constraint.
Another disadvantage is due to the not always perfect tightness of the connection joints themselves both during installation and during service, in so far as they are frequently under excessive stress because they are rigidly constrained in a fixed and integral way to the body itself of the manifold.
Furthermore, the excessive curvature of the pipes, which at times it is necessary to provide, during installation, to enable joining of the pipes of the panels to the manifolds, precisely because often the pipes themselves are made of polybutylene (PB) or cross-linked polyethylene (PEX), is a cause of undesirable tensioning stresses that frequently cause damage to the pipes themselves both in the course of installation, with waste of time for their replacement, and during running of the system.
From the foregoing there clearly emerge the disadvantages of the known art regarding known rigid manifolds for ceiling-mounted and wall-mounted radiant thermal-conditioning panels, which do not satisfy- completely the needs of companies for abbreviating the times of execution and consignment of the systems, nor do they provide any guarantee of duration over time. The main purpose of the present invention is to overcome said limitations of the known art by optimizing the production of said systems, simplifying their assembly and reducing the corresponding installation times. The present invention concerns a manifold for radiant panels of ceiling-mounted and/or wall-mounted thermal-conditioning systems, characterized in that it is of a space type, i.e., with two-dimensional and three-dimensional configurability, in so far as it is equipped with at least one pipe fitting, which can be fitted on the fixed ends of the body of the manifold by purposely provided engagement means. Said connector, thus constrained on the manifold by said engagement means, can turn freely about its axis of fitting on the manifold itself. The idea of producing a manifold with pipe fittings that are able to turn about the axis of the fixed ends, in order to facilitate assembly and installation of the radiant panels for wall-mounted and/or ceiling-mounted thermal-conditioning systems, is completely new and can also be produced at an industrial level.
A better understanding of the invention will be obtained from the ensuing description, with reference to the annexed drawings, which regard a non-limiting example of embodiment, wherein:
Figure 1 is a front view of a preferred embodiment of the manifold 1, where there is evident the presence of a pair of preferably elbows 2, with fitting guaranteed by the presence of engagement means 3; Figure 2 is a three-dimensional view of the same preferred solution illustrated in Figure 1, where more clearly evident are the characteristics of the manifold 1 described in the present invention, which is equipped with said elbows 2, which can turn through 360° about their axes of hinging on the manifold 1;
Figure 3 is a cross-sectional view of the manifold 1 of Figure 1, where there may be seen, in particular, the conformations and the positions both of the engagement means 3 of the pipe fittings 2, which swivel about the axis 5 of the fixed ends 6, through which there occurs fitting of the pipe fittings 2 on the body 8 of the manifold 1, and the seal rings 9 that guarantee tightness to the flow of the fluid within the pipe fittings and the manifold, as likewise evident is the presence on all the ends of the pipe fittings 2, as well as on the heads 11 of the manifold 1, of fast couplings 10.
As emerges from Figures 1, 2 and 3, the manifold 1 described in the present invention is further characterized both by its conformation, designed to be reproduced in a simple, fast and economically advantageous way, and by the corresponding ease of assembly of the pipe fittings 2 on the manifold 1 itself, which render the modalities of installation of the manifold 1 on the radiant panels for ceiling- mounted and wall-mounted thermal-conditioning systems peculiar and completely new. Known manifolds usually have pipe fittings 2 of a fixed type, with axes 5 of the fixed ends 6 perpendicular to the fixed axis 4 of the manifold, and present only along one and the same generatrix of the cylinder of the manifold. Known manifolds are fitted usually by means of plastic welds to the supply pipe of the system of the thermal- conditioning panels. There can be applied on said pipe fittings of a known type fast-coupling connectors for insertion of the pipes of the radiant panels.
In the present invention, instead, each pipe fitting 2, as likewise the ends or heads 11 of the manifold 1, is equipped with fast-coupling connection means 10; however, it is possible to position the pipe fittings 2 along any generatrix of the cylinder of the body 8 of the manifold 1; in addition, each of said pipe fittings 2 has one degree of freedom in its rotation about the axis 5 of the fixed ends 6 of the manifold 1.
On known manifolds, the possible insertion of fast couplings is obtained only on account of the presence of metal fasteners present within said fast coupling, which in any case do not guarantee gripping of the joint itself, whilst in the present invention the individual pipe fittings 2 are constrained to the body 8 of the manifold 1 by said engagement means 3, which, instead, guarantee a secure grip without any possibility of displacement or exit of the pipe fitting 2 from the fixed ends 6 projecting from the body 8 of the manifold 1. Furthermore, whilst the known manifolds are of the simple linear type or at the most co-planar, the present manifold 1, on account of the presence of at least one pipe fitting 2, which swivels about the axis 5 of the fixed ends 6 of the body of the manifold 1, is of a space type.
The possibility of effecting rotation of the individual pipe fitting 2 about the axis 5 of the fixed ends 6 of the pipe fitting 2, guarantees resistance to the stresses that said manifold and/or the pipes of the network or coil of the radiant panels undergo during installation and in service. The manifold 1 for radiant panels of ceiling- mounted and wall-mounted thermal-conditioning systems is completely new in so far as it has a configuration of a space type and is easy to produce at an industrial level.
The manifold 1 for radiant panels of ceiling- mounted and wall-mounted thermal-conditioning systems is in fact new in that it is equipped with at least one pipe fitting 2 that can swivel about the axis 5 of the fixed ends 6. Also appearing in the attached drawings is the secondary axis 7 of the pipe fitting 2.
Each pipe fitting 2, as may be noted from Figures 1, 2 and 3, can be rotatably costrained to the manifold 1 via engagement means 3, which bestow one degree of freedom on the pipe fitting 2, enabling the latter to turn through 360° with respect to its axis 5 of the fixed ends 6.
Installation of the pipe fittings 2 is made along the generatrices of the cylindrical body 8 of the manifold 1, perpendicular to its axis 4 by fitting said pipe fittings 2 on the fixed ends 6.
In the preferred embodiment described, said engagement means 3 are constituted, preferably but not exclusively, by at least one elastic ring that can be fixed by snap action on purposely provided teeth that project radially from the fixed end 6 of the manifold 1.
Installation of the manifolds 1 thus assembled does not present particular technicalities, nor does it require specific skills on the part of installers.
Furthermore, the installation of the manifold 1 according to the invention is even more convenient and faster than that of the ones currently known, it being sufficient to follow the procedure for assembly, simply noting the arrangement of its constituent elements, represented in a preferred, but non-limiting, embodiment shown in Figures 1, 2, and 3.
In particular, Figure 3 is a cross-sectional view of the manifold 1, from which there emerges the presence of a plurality of sealing means or gaskets 9, as likewise the preferred position for insertion of said engagement means 3.
The preferred materials of which said manifold can be made are plastic, but it may also be made of any metal or non-metal material suited to the purpose. The advantages of the invention described herein derive fundamentally from the fact that a manifold 1 has been devised that is equipped with swivel pipe fittings 2, which are ideal in residential and industrial applications, such as that regarding installation of radiant panels for thermal-conditioning systems, which are today particularly important owing to the fact that they are able to contain thermal losses very effectively.
Additional and by no means secondary advantages of the present manifold 1 as compared to rigid, linear and co-planar manifolds already known to the art lie in having obtained pipe fittings 2 that can be easily oriented towards the delivery and return points of the pipes or coils of the radiant panels, with undoubted and incomparable guarantees of tightness and speed of installation. Further advantages are present both in the minimization of the times of production of the manifolds 1 themselves and in the marked reduction of the times for assembly of the manifolds, during the step of installation of the thermal-conditioning system, precisely on account of the constructional simplicity of the invention 1, together with:
- minimization of the production costs;
- reduction of the installation times; - minimization of the installation costs;
- high flexibility of assembly and installation;
- minimization or elimination of the stresses present during installation and service on the pipes or coils of the radiant panels when fitted to the manifolds 1 via the various pipe fittings 2.
Said advantages enable an incomparable convenience in the purchase and in the use of the manifolds' 1 according to the present invention by firms that install radiant panels of the ceiling-mounted and/or wall-mounted type, fully meeting the requirements of the latest directives on energy containment of residential and industrial buildings.
Yet another advantage is represented by the fact that, given the same flow rate with respect to current standards, the invention presents a high degree of lightness of the individual manifolds, which, once assembled on the radiant panels, considerably reduce their weight, which is a very advantageous characteristic during transportation, installation, de- installation and disposal.
It is also evident that numerous modifications, adaptations, integrations, variations, and replacements of elements with other functionally equivalent ones may be made to the embodiment described herein purely by way of non-limiting illustrative example, without this implying any departure from the sphere of protection of the ensuing claims.
For example, according to the present invention, as an alternative to the elbow 2 (having an angle of
90°), it is possible to use pipe fittings with angles comprised between 0° and 90°, such as for example 0°,
30°, 45°, 60°, etc.
