Abstract
The invention relates to a central air-conditioning air flue with a slit valve. The air flue is provided with an air flue body and 3-5 air outlets; and the air outlets are square, the side length of the air outlets is a, the air outlets are formed on a base plate of the air flue, and the cross section of the air flue body is rectangular. The central air-conditioning air flue is characterized in that an air guide passage installed in a manner of being closely attached to the base plate of the air flue body is arranged inside each air outlet, and each air guide passage is divided into an air inlet, a passage body and an air outlet flow guide section, wherein each air inlet faces the direction of an air source, and the air inlets and the passage bodies are in shapes of arches with same semi-circle cross sections. The passage bodies are connected with the air outlets through the air outlet flow guide sections in an arc-shaped smoothing manner, the distances between the sides, close to the outer airs, of the edges of projections of the passage bodies on the base plate of the air flue body and the lateral edges of the air outlets range from 0.1 a to 0.2 a, the length of the passage bodies ranges from 1 a to 2 a, and the length of the air inlets ranges from 0.5 a to 0.8 a; one-way valves opening inwards are arranged at inlets of the air inlets, the valves are opened and closed through torsion springs, slit-shaped holes are arranged on the valves, and the slit directions of the slit-shaped holes are parallel to the base plate of the air flue body; and the door plank porosity of the valve closest to the air source ranges from 55% to 60%, the door plank porosities of the valves are decreased along with increase of the distances between the valves and the air source, and the lowest door plank porosity is 20%.
Description
Technical field
The present invention relates to ventilating duct for air-conditioner.
Background technology
Design and the installation in air channel are the important component parts during central air-conditioning is installed, and the effect of Duct design and installation, directly determines the operational effect of air-conditioning and the Expenditure Levels of the energy.Passage of central air conditioner of the prior art is adopted the material such as aluminium sheet, galvanized sheet more and is made and inner lining as thermal insulation material, and in position opening for air-out, but traditional duct outlet design is difficult to accomplish that air-out is even, often air output successively decreases from the distance of wind regime according to air outlet, but Chinese patent ZL201320532538 discloses a kind of air-conditioning duct, adopt the mode of the flow deflector at air outlet place design differing heights, but we find that this flow deflector causes larger resistance to the flow field in air channel, cause the loss of the energy.China ZL201320111164.2 discloses a kind of current-sharing air channel, adopt reducing air channel and the shielding plate that can adjust air port area, but we find, reducing air channel is from processing or install all comparatively difficulty, and shielding plate is not easy to control air output, and this noise that easily generation is larger under air-out condition of catch.Therefore provide a kind of can realize automatically regulating and wind regime apart from different air outlet amounts and the air channel that structure simply should not produce noise becomes in prior art the problem needing to solve.
Summary of the invention
For solving aforementioned technical problem, the invention provides a kind of passage of central air conditioner of tool slit valve, described air channel has air channel body and 3-5 air outlet, air outlet is square, its length of side is a, air outlet is driveed in air channel base plate, this body section of air channel is rectangle, it is characterized in that, in air outlet inside, there is the wind-guiding runner be close to air channel body base plate and installed, wind-guiding runner is divided into air inlet, runner body and air-out diversion section, air inlet is towards wind regime direction, it is identical semicircular arch that described air inlet and runner body are cross section, air-out diversion section is adopted runner body and air outlet to be adopted arc in smoothing junction, wherein the projecting edge of runner body on the body base plate of air channel is 0.1a-0.2a near the distance of air outlet side and air outlet side, runner body length is 1-2a, air inlet length is 0.5-0.8a, there is the check valve inwardly opened in air inlet import department, described valve adopts torsion spring to open and close, valve has slit-shaped apertures, the slit direction of slit-shaped apertures is parallel to air channel body base plate, door-plate porosity from the nearest valve of wind regime is 55-60%, the door-plate porosity of valve increases according to the distance from wind regime and reduces, minimum is 20%,
Described air channel inner surface is with heat-insulation layer.
Passage of central air conditioner provided by the invention, at the additional one section of wind-guiding runner towards wind regime in air outlet surface, and wind-guiding runner has Semicircular arched air inlet, integrated environment in space near air outlet and air channel can be separated, thus make blast in air channel be tending towards homogeneous, thus the air outlet amount making distance wind regime different can be basically identical, be convenient to the layout in air channel, the valve with slit-shaped apertures is set in the air inlet import department of wind-guiding runner simultaneously, can make to control air output by adjustment valve door-plate porosity, adopt this design, can make the most of parts of wind-guiding runner except valve door-plate all can be general, and air output can be controlled by changing valve door-plate porosity, make the layout of air outlet more flexible, the installation of various space environment can be adapted to.
