Embodiment 1

[0018] The cloth air duct with thermal insulation function of Example 1 includes a three-layer structure, the outer layer is a cloth fiber fabric layer 1 , the middle layer is a mesh layer 2 , and the inner layer is a PVC film layer 3 . The mesh layer 2 has a thickness of 0.5 mm and is composed of multiple layers of flame-retardant mesh cloth. The PVC film layer 3 is a PVC film with a thickness of 0.02 mm added with a flame retardant on the flame-retardant mesh cloth of the mesh layer 2 .

Embodiment 2

[0019] The cloth air duct with thermal insulation function of Example 2 includes a three-layer structure, the outer layer is a cloth fiber fabric layer 1 , the middle layer is a mesh layer 2 , and the inner layer is a TPU film layer 3 . The mesh layer 2 has a thickness of 0.5 mm and is composed of multiple layers of flame-retardant mesh cloth. The TPU film layer 3 is a TPU film with a thickness of 0.02 mm added with a flame retardant on the flame-retardant mesh cloth of the mesh layer 2 .

[0020] Lay the above-mentioned cloth air duct with thermal insulation function on a 30-meter conveying pipeline, and lay a 30-meter ordinary cloth fiber air duct at the same time. Under the condition of 50°C inlet air supply temperature, after testing, the air duct with thermal insulation function of the present invention The outlet temperature drop of the pipe is smaller than that of ordinary cloth fiber duct.

Abstract

The invention relates to a cloth duct with a heat preservation function. The cloth duct is characterized in that cloth fiber is taken as an outer layer, a mesh fabric is taken as a middle layer, and a PVC (polyvinyl chloride) film or TPU (thermoplastic polyurethane) film added with a fire retardant is taken as an inner layer. According to the cloth duct, on one hand, the thickness of the a cloth air duct is increased, and the thermal-conduction resistance is enhanced; and on the other hand, the middle mesh layer is added, so that a gap is reserved between the inner layer and the outer layer, and the thermal resistance is enhanced further. The cloth duct with the heat preservation function has the benefits as follows: on the premise that the installation material and the installation project amount are not added, the heat retaining property of an air supply duct can be enhanced, the air supply temperature is guaranteed, and energy conservation and consumption reduction are realized; and the construction is simple, and the installation is convenient.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cloth air duct for air supply of air conditioning. Background technique [0002] Air conditioning plays an important role in improving indoor air quality, controlling the level of indoor air pollutants, and improving indoor human comfort. In the prior art, the air supply ducts of air conditioners are mostly cloth air ducts. As a flexible air supply end, the cloth air duct has the characteristics of light weight, detachable and washable, and saves installation man-hours. At the same time, it can effectively avoid problems such as surface condensation and dust accumulation encountered in the use of traditional ventilation systems. Most of the cloth air ducts in the prior art are made of cloth fiber materials, which diffuse into the room through the pores of the porous fibers or the small holes on the surface, and exchange heat and moisture with the indoor air. Its dis...
