Description
Technical field
The present invention relates to air-conditioner technical field, more particularly to a kind of annular air fresh air component and air-conditioner.
Background technology
With the improvement of people ' s living standards, comfortableness requirement of the people to indoor environment is significantly improved.It is traditional empty
The heat exchange theory of device is adjusted to be limited to indoor air-flow reciprocation cycle heat exchange, but with the increase of heat-exchange time, indoor CO2, powder
Dirt and toxic and harmful equal size can gradually rise, and the peculiar smell release of air conditioner body material, has a strong impact on indoor ring in addition
Border comfortableness impression and health.
Therefore, in order to solve the above problems, at present, existing new wind devices by by outdoor gas introduce interior after,
Under the relatively comfortable temperature conditions of control, it is ensured that the faint malleation of indoor environment, so as to the dust that makes indoor deposition more long and harmful
Gas etc. is automatically drained out by indoor gap, door and window etc., keeps the lasting pure and fresh of interior.
But, the conventional blower fan of new wind devices is axial flow blower at present, when using, the air-flow of fan blade conveying axial direction, by room
Interior is incorporated into after outer gas is heated.Its shortcoming is that axial flow blower blowing air velocity is fast, and is more concentrated, when fresh air is blown into
Sense of blowing on one's face is relatively strong, and diffusion velocity is slower, and comfort level is poor when causing to use, it is impossible to meet the comfort level requirement that user uses.
The content of the invention
Fresh air component and air-conditioner it is an object of the invention to propose a kind of annular air, to solve to deposit in the prior art
The poor technical problem of comfort level.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of fresh air component of annular air, including air channel, the air channel include the air inlet and air outlet that are oppositely arranged,
Motor is provided with the air channel, the motor connection has centrifugation blade；
The outer rim of the inwall in the air channel and the centrifugation blade forms annular air supply channel, the air inlet and/or institute
State air outlet and be provided with heat exchanger.
Further, less than the diameter of the air outlet, the air channel is along air inlet to air-out for the diameter of the air inlet
Mouth direction is provided with curved transition sections.
Further, the motor connection has mounting seat, and the mounting seat is connected with the air channel.
Further, ring grille is provided with the air outlet, the ring grille is sheathed on the outer of the mounting seat
Edge, the mounting seat is connected by the ring grille with the air channel.
Further, a diameter of D of the air inlet1, a diameter of D of the centrifugation blade2, the diameter of the air outlet
It is Dmax, the width of annular air supply channel is L, and above-mentioned parameter meets relationship below：
D2>D1,0.2D1 2≤0.25Dmax-L2≤0.4D1 2。
Further, the heat exchanger includes an annular copper pipe or many annular copper pipes being socketed successively, described in every
Polylith fin is connected with annular copper pipe, the polylith fin is set by the center of circle of the center of the annular copper pipe in divergent shape.
Present invention also offers a kind of air-conditioner, including annular air fresh air component.
Further, including multiple annular airs fresh air component, the fresh air component of multiple annular airs can
Dismounting modularization is installed.
Further, also including protection shell, the protection shell is in cuboid, and the protection casing is located at described
The outside in air channel.
A kind of fresh air component of annular air that the present invention is provided, when using, starts motor, and motor drives centrifugation blade to turn
Dynamic, centrifugation blade rotation acting makes centrifugation blade center produce negative pressure, external air flow to be entered by air inlet, be pressed into by atmospheric pressure
Centrifugation blade, and after giving kinetic energy with centrifugation blade, annular air supply channel is spread and entered to surrounding, finally sent by air outlet
Enter interior.Wherein, air-flow completes heat exchange at air outlet and/or air outlet with heat exchanger.Indoor original air is due to centrifugation
The faint static pressure that fan blade gives, has stepped through room space discharge outdoor, so that the overall ventilation for realizing environment.
The fresh air component of the annular air, during ventilation, the air-flow of annular air is in dispersity, can rapid dispersion to interior
Each corner, air exchanging rate is very fast, meanwhile, the air velocity that centrifugation blade itself is produced is relatively low, and is distributed air-supply,
And then causing that human body does not feel as strong sense of blowing on one's face, the comfort level that user uses is higher.
A kind of air-conditioner that the present invention is provided, by setting the fresh air component of above-mentioned annular air, is capable of achieving quick air-supply
Take a breath, and annular air air-flow more disperses, without strong sense of blowing on one's face, meanwhile, noise is smaller when centrifugation blade is blown, and then makes
The comfort level obtained when the air-conditioner is used is higher.
