Problems solved by technology

It also often happens that some parts of the conveyor path are difficult to access, for example near the roof
In addition, it is also difficult to monitor and verify the quality and uniformity of the installation, resulting in possible gaps in the installation, which lead to the risk of cold spots and condensation forming in the delivery pipes

Embodiment Construction

[0021] Now refer to the attached figure 1 , where a longitudinal section through one wall of the duct section 1 , 2 of two rectangular sections (cross sections) is shown. Reference numeral 3 shows the relationship of the duct housing 2 and the air passage 3 extending through both duct sections 1 , 2 . The duct sections 1, 2 are formed by steel sheet walls 4 and each duct section has at its end an upstanding flange 5, 6 by means of which adjacent duct sections can pass through the flanges. Both edges 5, 6 are fastened together by bolts or rivets (not shown). In this embodiment a gasket 7 forms a joint seal of foamed plastic or butyl material and is located between the flanges 5, 6 to provide thermal insulation. Each conveying section 1 , 2 is lined with a thermally insulating lining 8 of a thermally insulating lining material comprising a foamed or expanded synthetic plastic material, such as a laminated phenolic substrate.

[0022] The insulating lining 8 is fastened to the...

Abstract

The invention discloses a duct section 1, 2 for an air distribution system, the duct sections including an elongate frame 2, 4, 24 having two opposed flange members 5, 6 each having an opening forming an air passage therein. A plurality of the duct sections are able to be joined together through the flanges to form an air passage of desired length. Each duct section 1, 2 is lined with a thermal insulating material 8, 25 to provide a thermally insulating lining to the air passage, the ends 11 of the lining 8 being at least flush with the end faces of the flanges so that when adjacent duct sections are secured together, the thermal insulation lining 8 of adjacent duct sections is arranged to provide a continuous insulating lining of the air passage.

Description

technical field [0001] The present invention relates to a duct system and in particular to a duct (pipe, conduit) for an air distribution (distribution) system. Background technique [0002] Conveyor systems for distribution of ventilation or heating air are widely used in offices, warehouses, shops and factories. In many installations, it is required that the ducts be thermally insulated. Typically, this is accomplished by first building the entire conveyor system and covering the outside of the conduit with thermal insulation on site. There are several disadvantages to using this arrangement. Since the conveyor road is generally set at a higher level from the ground, scaffolding must be built for workers installing thermal insulation facilities, but there is still a significant risk of falling that poses a safety hazard. Workers working in these conditions are inevitably less productive than if they were working at ground level. It also often happens that certain parts...
