BACKGROUND OF THE INVENTION

The invention relates to an air conditioning system element according to the preamble of claim 1, comprising a support structure and an insulating material. The invention further relates to a method for manufacturing an element of an air-conditioning system according to the preamble of claim 6.

Centralized air-conditioning systems for buildings and industrial properties connect many, very different spaces. To maximize fire safety, air-conditioning systems connecting the premises must be made fire-resistant 10 so that the fire cannot be transmitted through the hot flue gases transmitted through the air-conditioning systems or from the air-conditioning system to the building structures. In air conditioning systems, flue gas dampers are used to prevent the spread of fire, and their tight closure prevents hot flue gases from spreading through the air conditioning systems, whereby any possible fire can be contained and prevented. In addition to the flue gas dampers, the elements of the air-conditioning systems must be insulated so that the heat carried by the hot flue gases cannot pass into the structures of the buildings. To prevent this, various ceramic materials are currently used as insulating material in air-conditioning systems, which are attached to element-20 air-conditioning systems. These ceramic masses collect heat and prevent it from spreading to building structures. The insulating materials to be installed must always be inspected: to ensure sufficient fire safety and to comply with fire regulations.

Commonly used insulators are prefabricated sheet-like insulators: / ·· 25, which are attached in pieces to insulated air-conditioning system elements. The quality of such insulating pieces can be checked before they are installed in the elements of the air-conditioning system. New ceramic materials have such properties that they are substantially fluid when installed · ·. insulated elements. After installation, these materials will solidify * · 30 to form a solid insulation. For example, the feature described above allows the insulating material to be poured into the insulating element, which facilitates: and streamlines the insulation process. These customizable ceramic masses are used. . the problem with this has been to check the quality of the insulation. When such-. : The moldable ceramic mass is mounted on the 35 elements of the air-conditioning system and must be checked for quality to ensure that no large cavities without insulating mass remain inside the mass during its installation. At cavity 115070 2 d, the insulation does not work as desired, but heat is transferred to the structures, which may cause a fire hazard. To avoid cavities, the ceramic insulating material is randomly checked by removing pieces of insulating material from randomly selected locations. Removal of the pulp is difficult and always requires breaking of the mold-5 comprehensive or cast pulp, whereby the pulp often comes off as uncontrolled pieces, which impairs the repair of the insulation to its original proper condition.

Thus, there has become a need to improve the insulation so that the quality of the insulation mass can be checked more easily and the mass can be easily repaired. Inspection can be facilitated by adding features to the elements and insulation of the air conditioning system that facilitate removal and re-installation of the pulp.

FIG. 1b shows a cross section of the air conditioning system of FIG. 1a, wherein the duct element 1 comprises a support structure In this type of solution in which a substantially fluid insulating material 6 is fastened between the outer and inner shells 4, 5 of the duct element 1, it is possible to inspect the sealing material after the manufacturing of the air conditioning system when the outer sheath is made.

sex, so that it can be at least partially removed. In the manufacture of such an insulating arrangement, which initially uses substantially fluid material which subsequently solidifies, such insulating material adheres to the supporting structures of the elements to be insulated, e.g., the outer and inner liner of Figure 1a and 1b. In the following, arrangements for isolating the duct element 1 and the seal element 2 of the air-conditioning system, in which the insulating material attached to the elements comprises a membrane, will be considered. By tubular duct element is meant an elongated and tubular element of any cross-section along which the air-filing system passes through the spring.

Figs. 2a and 2b show a tubular duct element of an air-conditioning system in which the support structure comprises an outer sheath 4 and an inner sheath 5 between which an initially substantially fluid insulating material 6 is secured. In a preferred embodiment of the present invention, the film in the insulating material 15 is preferably placed at least partially on the inner surface of the removable outer sheath 4 between the outer sheath 4 and the insulating material 6 or between the inner sheath 5 and the insulating material 6. The film may be made of any suitable material, preferably a Teflon or molding oil based material, which prevents the sections or support structure of the insulating material and the insulating material from adhering to one another. With the membrane being the outer sheath 4 and ... between the insulating material 6, the sole can be removed during inspection; The film is preferably placed on the surface of the outer sheath during manufacture, so that the insulating material and the sheath adhering to one another are prevented from drying and curing the insulating material. In general, such a removable outer sleeve is formed with a longitudinal seam which is closed by screws, rivets or the like. This seam can thus be opened and the sheath applied so that it can be threaded away without breaking the insulating material. If the diaphragm 7, in turn, is mounted between the inner sheath 5 and the ··· insulating material 6, the inner sheath must be removed from the inside of the duct element.

·. In these cases, it is possible to inspect the insulating material 6 either from the inside or from the outside.

In another embodiment of the present invention, the initially substantially fluid dielectric material 6 is secured, preferably by casting, between the inner and outer jacket 4,5. In this embodiment, the insulator; Inside the material 6, a membrane 7 is inserted during manufacture which divides the insulating material 6 into two removable parts. The film may be made of any suitable material, preferably a Teflon or molding oil based material, which prevents the insulating material sections or support structure and the insulating material from adhering to one another. 2a and 2b, the insulating material of the duct element 1 shown in Figures 2a and 2b is adhered to the inner and outer sheaths 4, 5 when it is mounted 5, whereby the outer sheath 4 is detached so that the insulating material 6 The part of the insulating material 6 attached to the inner sheath 5 on the side remains in place in the duct element 1. Once the outer sheath 4 and the outer part of the insulating material 6 have been removed, the insulation quality can be conveniently checked without breaking the insulation. After inspection, the removed outer sheath 4 and the insulating material attached to it are easy to re-install.

Figures 3a and 3b show a duct element 1 of the air-conditioning system according to the present invention comprising an inner sheath 5 and an insulating material 6 according to the invention with a membrane 7 attached thereto. In this case, the insulating material 6 forms the outer surface of the duct. As in Figures 2a and 2b, the film 7 may be mounted during manufacture inside the insulating material 6 or between the inner sheath 5 and the insulating material 6. In the former case, during the inspection of the insulating material 6, only the top part of the insulating material 20 is removed from the insulating material up to the membrane 7 and thus the inspection can be performed on the insides of the insulating material. In the latter case, the insulating material 6 is removed from the inspection point up to the inner sheath 5.

:; In the embodiment of Figures 4a and 4b, the duct element 1 of the air-conditioning system comprises at least a partially detachable outer sheath 4, wherein the insulating material 6 attached to the inside of the outer sheath 4 forms a channel: an inner surface. In this embodiment of the present invention, the membrane 7 is mounted either inside the insulating material 6, whereby it divides the insulating material 6 into two parts, or between the outer sheath 4 and the insulating material 6. By installing the membrane 7 inside the insulating material 6, the insulating material 6 is detached during the inspection up to the membrane 7 with the outer sheath 4. But if the diaphragm 7 is placed between the outer sheath 4 and the insulating material 6, only the outer sheath 4 is removed during inspection.

5a and 5b, insulators are provided on both sides of the duct element support structure 8 of the air-conditioning system; 6, whereby the outer and inner surfaces of the duct are formed of insulating material. 6. In this case, one or more membranes 7 may be optionally used. In accordance with the present invention, the membranes may be mounted either inside the insulating material 6, between the supporting structure 8 and the insulating material 6, or in a combination of the above locations. By using several films 7, it is possible to inspect the insulating material 6 at different depths without breaking the entire insulation.

In the following, with respect to the examples of the present invention, a corresponding isolation arrangement of the closing element of the duct element 1 of the air-conditioning system will be considered. The isolation arrangement of the closure element 2 is characterized by the same features as the isolation of the channel element 1 described above.

Fig. 6a is a front view of a typical barrier element 2, by means of which the duct element 1 of the air-conditioning system can be sealed in case of fire or otherwise if necessary. Such a closing element 2 which is pivoted on the channel element 1 to insulate the channel must be insulated in the same way as the channel element.

Fig. 6b is a cross-sectional view of an embodiment of the closure element 2 of Fig. 6a. Such a closure element comprises a support structure 9 and an insulating material 6 attached thereto. The solution of Figure 6b has at least a partially detachable support structure 9 between which the insulating material 6 is secured. The inspection of the insulation of the sealing element 2 is carried out in the same way as the inspection of the insulation of the hollow element 20, with or without the insulating material. a membrane 7 is mounted on the surface during the fabrication of the element. In the solution of Fig. 6b, the membrane 7 is mounted during the fabrication of the insulation material 6! »*: · 'Inside or between the insulating material 6 and the supporting structure 9. With the membrane 7 mounted inside the insulating material 6, during inspection, the support structure 9 on the other side of the sealing element 2 can be removed, whereby part of the insulating material 6: comes off with the supporting structure. The same applies when the membrane 7 is mounted between the insulating material 6 and the support structure, but only one of the support structures 9 is removed during inspection and the insulating material remains in place. Such a solution is shown in Fig. 7, in which the tubular element 30 comprises an inner sheath 5, an insulating material 6 mounted around the inner sheath 5, an outer sheath 4 and a membrane 7 mounted between the insulating material 6 and the outer sheath 4 for detaching the outer sheath 4.

Fig. 6c shows another isolation arrangement of the closing element 2; an embodiment in which the insulating material 6 is attached only to the support structure; 35 9 to the other side. In the embodiment of Figure 6d, the insulating material 6 is fastened to both sides of the support structure 9 during manufacture. In these two cases, as before, the membrane 7 may be mounted inside the insulating material 6 or between the supporting structure 9 and the insulating material 6 during the fabrication of the element. Also, more than one membrane may be used in any insulating arrangement of the barrier element. For example, the use of two diaphragms 5 is particularly suited to the insulating arrangement of Figure 6d, in which separate layers of insulation are provided on each side of the support structure 9.

In accordance with the principles of the present invention, the other air conditioning system components may also be subjected to an insulating arrangement according to the invention, which initially utilizes a substantially fluid dielectric material on or in which a membrane of the invention is applied. Such components of an air conditioning system may include, for example, different valves.

According to the invention, the membranes may be multiple and may be disposed in a plurality of positions according to the above embodiments. The membrane may also be of any material which enables the insulating arrangement to be used in accordance with the invention. Preferably, the film is a Teflon or mold oil based material, but it may also be, for example, a plastic sock or similar film or layer made of another material that is threaded around the duct element or inside the barrier element. It is characteristic of the insulating arrangement according to the invention that the membrane can also be mounted only on a part of the air-conditioning system or on certain parts of its elements. Additionally, the film may be mounted during manufacture, if desired, inside the insulating material, on the surface of the insulating material, or on the surface of the supporting structure.

A person skilled in the art will appreciate that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiment -: ...: 25 are thus not limited to the examples described above, but may vary within the scope of the claims.
