Pulley type air pipe system for central air-conditioner

Abstract

The invention discloses a pulley type air pipe system for a central air-conditioner, and belongs to the field of building installation. The pulley type air pipe system is composed of an air pipe, an insulating layer covering the outer surface of the air pipe and a hoisting mechanism; the air pipe is formed by splicing a plurality of air pipe units end to end and is hoisted through the hoisting mechanism to be fixed to a roof; the hoisting mechanism is composed of fixed pulleys, adjusting heads with the adjustable lengths and steel cables, the multiple pairs of fixed pulleys are fixed to the roof, and one steel cable is arranged between each pair of fixed pulleys; and the steel cables are bent in a U-shaped manner, the air pipe is placed on the steel cables and hoisted and fixed through the steel cables, and the two ends of each steel cable are wound around the corresponding fixed pulleys to be detachably and fixedly connected with the air pipe through the corresponding adjusting head. The air pipe system for the central air-conditioner is more efficient in installation, adjustment and detachment.

Description

technical field [0001] The invention belongs to the field of building installation. Background technique [0002] The air conditioner air duct is used by the air conditioner to use the cold and heat generated by the host to centralize the return air (or the mixture of return air and fresh air) from the room for air treatment, such as cooling, heating, humidification, dehumidification, purification, etc. and then into the indoor channel. [0003] The air ducts commonly used in central air conditioners include the following types: galvanized steel sheet air ducts, inorganic glass fiber reinforced plastic air ducts, composite glass fiber board air ducts, and fiber fabric air ducts. [0004] Galvanized thin steel air duct: one of the earliest used air ducts, made of galvanized thin steel, suitable for the transportation of general gas with low moisture content, easy to rust, no heat preservation and noise reduction functions, long production and installation period specialty. ...

AI Technical Summary

Problems solved by technology

[0026] 1. Since the structure uses wood for cold insulation, it can no longer meet the fire protection requirements in today's increasingly stringent fire protection requirements

[0027] 2. Due to the cold bridge wood, the space occupied by the air duct increases correspondingly, which increases the elevation and cost of the entire building

[0028] 3. Because the air duct is installed at a certain interval, a hanger or bracket is required. The previous bracket installation method has cross-arms. Since the number and specifications of the cross-arms are difficult to accurately determine, it is generally processed on-site

Material cutting, drilling, rust removal, anti-corrosion, etc., not only take a long time to process, but also require high labor costs, occupy a lot of temporary space, and have many hidden dangers to safety and quality

[0029] 4. At the same time, regardless of various installation structures, the assembly and disassembly efficiency is not high
