Definitions

• the invention relates to an air conditioning system according to the preambles of claims 1 and 13 and comprising a support structure and an insulating material.
• present air conditioning systems use various ceramic materials as insulating materials, and they are fastened to the elements of the air conditioning systems. These ceramic masses gather heat and prevent it from spreading to the structures of buildings.
• the insulating materials to be installed must always be checked to ensure sufficient fire safety and to follow fire instructions.
• Generally used insulators are complete laminar insulating pieces made from a solid material and attached in pieces to the air condition- ing system elements to be insulated.
• the quality of such insulating pieces can be checked before being installed in the elements of an air conditioning system.
• the characteristics of new ceramic materials are such that they are substantially fluid before they are installed in the elements to be insulated. After installation, these materials solidify forming a solid insulation.
• the above- described property enables for instance the casting of the insulating material into the element to be insulated, thus facilitating and enhancing the insulation process.
• a problem in the use of these workable ceramic masses is checking the quality of the insulation.
• the checking can be facilitated by adding properties to the elements and the insulation of the air conditioning system to facilitate the detachment and the reinstallation of the mass.
• the object of the invention is to provide an insulating arrangement for an air conditioning system, solving the above problems.
• the air conditioning system of the invention is characterized in what is stated in the characterizing parts of independent claims 1 and 13, and in that the air conditioning system further comprises a film installed between the support structure and the insulating material and/or inside the insulating material, the film being formed using a substantially liquid material.
• the preferred embodiments of the invention are disclosed in the dependent claims.
• the invention is based on placing a film inside the insulator in the element of the air conditioning system upon installation, the film dividing the insulator into two parts.
• the material of the film is such that it detachably separates the insulator parts remaining on the different sides of the film or the insulator part and the support structure from each other in a manner allowing the insulating material to be detached upon checking from the element of the air conditioning system into two parts or allowing the support structure on top of the insulating material to be detached from the insulating material. In this manner the insulating material remains intact upon checking and the detachable part of the insulator is also detached easily. Thanks to the film, the insulating material is detached in the desired manner in pieces of a suitable size and depth, which are easily reinstalled in place after the checking.
• the film material is substantially liquid, whereby its installation in the insulating arrangement is easy and fast, and, when need be, the film can be made very thin.
• An advantage of the method and system of the invention is the ability to detach the insulating material in a controlled manner for checking, and to reinstall the detached insulating material easily in place after the checking.

In the previous case, only the uppermost partition of the insulat- ing material up to the film 7 is removed during checking of the insulating material 6, and the checking can thus be made on the inner parts of the insulating material. In the latter case, the insulating material 6 is removed up to the internal jacket 5 at the checking point.
• the conduit element 1 of the air conditioning system only comprises an at least partly detachable external jacket 4, the insulating material 6 fastened inside the external jacket 4 constituting the inner surface of the conduit.
