Abstract
The utility model relates to a fabric air pipe applied in a fabric air distribution system, which comprises the fabric air pipe. A hanging hook is positioned in intervals along the axial direction at the upper end of the fabric air pipe. The difference lies in that: the fabric air pipe is made of permeable fabric; a polyurethane film coat with micropores is covered on the internal surface or the external surface of the fabric air pipe; the aperture of the micropore in the polyurethane film coat is 10-15 Mum. In the utility model, a layer of polyurethane film coat with micropores is covered on the surface of the fabric air pipe, so that when the polyurethane film coat maintains even pressure and constant air blast of the air pipe, little quantity of air can permeates to the outside via the fabric air pipe. When the permeated quantity reaches certain volume, an air current layer that has a temperature similar to that of the inside of the pipe can be formed on the external wall of the air pipe. The air current layer can effectively prevent condensation, thus resolving the problem of condensed water during the air blast of the fabric air pipe as well as realizing excellent effect for air blast and air conditioning.
Description
Technical field
The utility model relates to a kind of fabric airduct that is used for the fabric air distribution system, belongs to room conditioning ajutage road technique field.
Background technique
In the room conditioning system, the air of adjusting temperature normally transmits by air-line system, and existing air conditioning wind pipe mostly is the rigidity airduct that metal or plastics are made.Had the fabric airduct in recent years in air-conditioning system, be called for short stringing, air-line systems such as the relative metal of fabric air-line system have simple in structure, easy for installation, are convenient to clean and advantage that fabricating cost is low.Existing fabric airduct is for avoiding its ventilative gas leakage, on fabric, all be coated with airtight stronger sealing layer usually, though such fabric airduct can keep the discharge pressure of longer distance, but because the inside and outside wall temperature difference of airduct is big, easily cause the condensation dripping phenomenon occurring, brought inconvenience to use.
Summary of the invention
Technical problem to be solved in the utility model is to be to overcome the deficiency that above-mentioned prior art exists and to design and a kind ofly can keep the not fabric airduct of condensation of equal force feed wind.
The utility model realizes that the technological scheme that problem adopted of above-mentioned proposition is: include the fabric airduct, the upper end edge axially spaced-apart of fabric airduct is installed on suspension hook, its difference is that described fabric airduct made by the gas permeability fabric, outside or inner face at the fabric airduct apply the thin polyurethane membrane coat that one deck is furnished with micropore, and the micropore size of thin polyurethane membrane coat is 10-50 μ m.
Press such scheme, described polyurethane film coating thickness is 50-200 μ m.
Press such scheme, adding in the described thin polyurethane membrane coat has fire retardant, to improve its fireproof performance.
Press such scheme, below the fabric airduct, offer jet hole as exhaust outlet.
The beneficial effects of the utility model are that the surface-coated one deck at the fabric airduct is furnished with the thin polyurethane membrane coat of micropore, this micro porous coating is when keeping the continuous air-supply of the equal pressure holding of airduct, have little air and pass through the fabric airduct to exosmosis, when infiltration capacity reaches a certain amount of, can pipeline outer wall form with pipe in the identical airflow layer of temperature, the formation of this airflow layer can prevent the generation of condensation phenomenon, the problem thereby the condensation that has solved the appearance when air-supply of fabric airduct drips reaches good air-supply and air conditioning effect.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural drawing.
Fig. 2 is the sectional structure chart of airduct among embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include fabric airduct 5, described fabric airduct is made by gas permeability fabric 5a, outer surface at the fabric airduct applies the thin polyurethane membrane coat 5b that one deck is furnished with micropore, the polyurethane film coating thickness is 50-200 μ m, the micropore size of thin polyurethane membrane coat is 10-50 μ m, micropore size circle is between water molecule and water vapour molecule diameter, can play the effect of waterproof and breathable, in the thin polyurethane membrane coat, add high stable type eight bromo ether fire retardant, to have improved the fireproof performance of airduct.Upper end edge axially spaced-apart at the fabric airduct is installed on suspension hook 4, makes airduct and is connected across indoor aerial guiding principle rope 3 and is connected by suspension hook, realize the fabric airduct indoor aerial suspention be connected extension.When the fabric airduct arrives the room conditioning place, can below the fabric airduct, offer the exhaust outlet of a plurality of jet holes 2 as airduct with side direction, carry out the exchange and the adjusting of temperature.Airduct connecting sleeve 1 can be installed in joint in fabric airduct termination, is used for the connection in aperture, fabric airduct joint.The other end of fabric airduct is a closed end.During use, air mainly is sent to by hydrostatic pressure by the jet hole of offering on system's airduct indoor, at indoor formation air-conditioning jet-stream wind, and forms uniformly big flow field.Simultaneously, it is indoor to also have the fraction air to be sent to by the fiber fabric layer infiltration, and the amount of infiltration is by the coating decision of fiber.When coating reaches certain uniform thickness, when infiltration capacity reaches a certain amount of, can form the airflow layer identical at pipeline outer wall with wind pushing temperature, thus the generation of stopping the condensation phenomenon.
Claims (3)
1, a kind of fabric airduct with film coating, include fabric airduct (5), the upper end edge axially spaced-apart of fabric airduct is installed on suspension hook (4), it is characterized in that described fabric airduct made by the gas permeability fabric, outside or inner face at the fabric airduct apply the thin polyurethane membrane coat that one deck is furnished with micropore, and the micropore size of thin polyurethane membrane coat is 10-50 μ m.
2,, it is characterized in that described polyurethane film coating thickness is 50-200 μ m by the described fabric airduct of claim 1 with film coating.
3, by claim 1 or 2 described fabric airducts, it is characterized in that below the fabric airduct, offering jet hole (2) as exhaust outlet with film coating.
