Description
Technical field
The utility model relates to ventilating duct for air-conditioner.
Background technology
The design in air channel is the important component part during central air-conditioning is installed with installing, and the effect of Duct design and installation, has directly determined 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 the design of traditional duct outlet 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 at the flow deflector of air outlet place design differing heights, but we find that this flow deflector causes larger resistance to the flow field in air channel, has caused 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 difficult, and shielding plate is not easy to control air output, and this larger noise of easy generation under air-out condition of catch.Therefore provide a kind of air outlet amount that automatic adjusting and wind regime distance is different and air channel that should not produce noise simple in structure of can realizing to become and in prior art, need the problem that solves.
Utility model content
In order to solve the problem of above-mentioned existence, the utility model provides a kind of passage of central air conditioner, there is an air channel body and 1-5 air outlet, air outlet is square, its length of side is a, air outlet is driveed in air channel body base plate, this body section of air channel is rectangle, it is characterized in that having in air outlet inside the wind-guiding runner of being close to air channel body base plate installation, wind-guiding runner is divided into air inlet, changeover portion, runner body and air-out diversion section, described air inlet is the arch in semi-circular cross section, opening is towards wind regime direction, runner body is the cuboid runner of square-section, adopt changeover portion by runner body and air inlet smooth connection, and adopt air-out diversion section by runner body and the smooth connection of air outlet arc, wherein the projecting edge of runner body on the body base plate of air channel is 0.1a-0.25a near the distance of air outlet side and air outlet side, runner body length is 1-2a, runner body section rectangle base is 1-1.2a, runner body section rectangle side and base length ratio are 0.5-0.8, transition section length is 0.2-0.5a, air inlet semi arch diameter is 1-1.1 with the ratio of runner body section rectangular base edge lengths, air inlet length is 0.5-0.8a, air inlet material thickness is 0.02-0.04a,
Described passage of central air conditioner, is characterized in that air outlet quantity is 2-5, and the distance between air outlet is greater than 25a;
Described air channel body internal surface is with thermal insulation separation thermosphere.
The passage of central air conditioner that the utility model provides, 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 near space air outlet and air channel can be separated, thereby make blast in air channel be tending towards homogeneous, thereby make the air outlet amount different apart from wind regime can be basically identical, be convenient to the layout in air channel, in the time that the distance between air outlet is set to be greater than 25a, this effect is more obvious.And while passing through our experiment wind-guiding runner air inlet section material thickness 0.02-0.04a, the noise causing can obviously reduce the air-out of wind-guiding runner time, has further improved the range of application in this air channel.
Brief description of the drawings
Fig. 1 is the wind-guiding flow passage structure schematic diagram of the utility model passage of central air conditioner.
Detailed description of the invention
