Definitions

• the present invention relates to the file of pre-insulated components for use in heating, air-conditioning and water supply applications.
• the pre-insulated components of the present invention have not been disclosed in the prior art.
• a further disadvantage occurring in air-conditioning, heating and water supply installations is the absence of pre-insulated collectors.
• Collectors constitute important components for the specific installations, since liquefaction phenomena occur thereon. Therefore, frequent maintenance is required on their insulations.
• the insulation of the collector during installation is a separate work for each installer, since there is no pre-insulated counterpart for immediate installation.
• An object of the present invention is to address advantageously the said disadvantages and failures of the prior art, by presenting pre-insulated components with suitable insulating material, which may be directly used in hydraulic installations.
• a further object of the present invention is to provide pre-insulated components that may be manufactured from polyvinyl chloride), also known as PVC, as well as other polyolefins including polyethylene and polypropylene.
• PVC polyvinyl chloride
• other polyolefins including polyethylene and polypropylene.
• a further object of the present invention is to allow easy union of the special parts used in hydraulic applications, either by the use of an appropriated adhesive or by special tapes.
• a further advantageous object of the invention is the perforation of the components for the injection of additional polyurethane by the installers during joining.
• a further object of the invention presents a pre-insulated collector with a suitable insulating and swelling material.
• a further object of the invention is to provide a pre-insulated collector, from which outputs for the heating, air-conditioning or water supply system are obtained.
• Figure 1 shows a pre-insulated collector which is used in heating, air- conditioning and cooling applications.
• Figure 2 shows a flexible pre-insulated 90°-angle component while Figure 3 shows a respective pre-insulated 45°-component.
• Figures 4(a)-(d) show other special pre-insulated components, which may be connected between them by screws, or male-female buttons, or even welded.
• Figure 5(a)-(b) shows pre-insulated 45°- and 90°-angles respectively, which are assembled by joining fully dissected parts.
• a collector (1), Fig. 1 is manufactured by an inner pipe (2) made of a suitable material for water distribution.
• Such materials include, but not limiting to, polypropylene, polyethylene, polyolefins in general, copper or iron.
• the outer sheath (4) of the collector (1) consists of a suitable coating material. Again, such materials include exemplarily polypropylene, polyethylene, polyolefins in general, copper or iron. Between the two sheaths the insulation material (3) is arranged. As insulation material polyurethane or any other swellable insulating material may be employed.
• the pre-insulated components may consist of flexible pre-insulated 90°-pipes, Fig. 2, or flexible pre-insulated 45°-pipes, Fig. 3, or even of tailor-made components, e.g. T-shaped ones, Fig. 4(c), wherein the outer sheath (4) is made of materials which are mentioned above and are suitable for uses in heating, air-conditioning and water supply applications.
• the said components may have an insulation made of polyurethane or other suitable insulating material, while they have holes (5) on their outer surface, through which an insulating material may be introduced as required during installation. In each hole (5), a cap is formed after the injection of the insulating material, which covers the hole (5).
• the insulating material as it is known in the current state of the art, is swollen to occupy any available space.
• 45°- and 90°-angular fittings may be manufactured from the pre-insulated pipe parts, Fig. 5(a) and Fig. 5(b), which are cut at 22.5° and 45° respectively and which are connected between them forming the desired angle.
• a joint may be made easily by the installer himself, ensuring the formation of a fully insulated angular connection.
• Tailor-made components, Fig. 4(a)-(d) may be connected between them forming essentially modified shapes corresponding to the individual installation requirements. These components have sockets (6) to be screwed between them by screwing.
• these may be made by respective male/female buttons, instead of screws, in order to be connected between them.
• the parts are made of polyvinylchloride, these may be connected by welding.
• the above-said components may be provided without an inner insulation (3), but the installer may insulate the space between the inner pipe (2) and the outer sheath (4) with the appropriated material through the holes (5).
