Embodiment
With reference to shown in referring to Fig. 1 to Fig. 3, according to an embodiment of the invention, indoor set includes through-flow fan blade 1, air channel 2, entered
Style grid 3 and heat exchanger 4, heat exchanger 4 are arranged between through-flow fan blade 1 and air-inlet grille 3, and heat exchanger 4 is included positioned at both ends
Straightway and the arc being connected between two straightways, in any one section of heat exchanger 4 institute in the plane, positioned at changing
The extended line of hot 4 outer peripheral two straightways of device intersects at O points, with where the straightway of the air inlet direction of through-flow fan blade 1
Side is the first side, and side where another straightway is the second side, line in O points and the side of air-inlet grille 3 first between end points and the
The angle formed between the straightway of side is C2, and the line and the second side in O points and the side of air-inlet grille 3 second between end points are straight
The angle formed between line segment is C1, and C1 is more than C2, and C1 and C2 difference range is 3 ° to 8 °.
When machine works indoors, the place side speed air flow of heat exchanger 4 of the air inlet institute direction of through-flow fan blade 1 is more
Height, the speed air flow of opposite side heat exchanger 4 is relatively low, and air from air-inlet grille 3 flow through heat exchanger 4 exchange heat during,
If air flow is larger, air velocity reduction may result in so that air velocity can not meet the air intake need of through-flow fan blade 1
Ask, therefore, in the place side of heat exchanger 4 of the air inlet institute direction of through-flow fan blade 1, it is necessary to reduce air flow, accelerate air stream
Speed, and on the heat exchanger 4 away from air inlet side, it can make air that there is larger flow so that air is entering through-flow wind
There is slower flow velocity before leaf 1, so as to ensure air from air-inlet grille 3 to the flow the air inlet of through-flow fan blade 1 and its
Flow velocity can match, and reduce air flow resistance, reduce air inlet/outlet loss, not reduce in air flow process due to flow velocity not
Match somebody with somebody and caused eddy current problem, reduce air flow noise, improve air-conditioning work performance.
C1 and C2 difference is limited to 3 ° to 8 °, can be according to the setting structure characteristic of through-flow fan blade to air-inlet grille 3
Rational deployment is carried out with the position of heat exchanger 4 so that the company in the less region of wind speed, O points and air-inlet grille between end points
Angle between line and the straightway of corresponding side is larger, can form larger air flow so that air is entering angle area
Behind domain, can be formed with through-flow fan blade needed for the air velocity that matches of wind speed, so as to carry out relatively slow change with heat exchanger 4
Heat so that the flowing of air and the heat exchange efficiency of heat exchanger 4 match, and avoid that air heat-exchange inequality occurs and heat exchange is insufficient
The problem of；In the region that wind speed is larger, the line in O points and air-inlet grille between end points and the folder between the straightway of corresponding side
Angle is smaller, can form shorter air flow so that air after angle region is entered, can be formed with through-flow fan blade needed for
The air velocity that wind speed matches, so as to enter after quickly being exchanged heat with heat exchanger 4 in through-flow fan blade 1, improve heat exchange efficiency.
Preferably, C1 and C2 difference is 5 ° to 6 °, can cause the wind speed in different air-out regions with air flow more
Matching, can not only reduce air flow resistance, and can effectively reduce air flow noise, improve air-conditioning work performance.
Preferably, C1 scope is 15 ° to 20 °.
Preferably, C2 scope is 10 ° to 15 °.
Preferably, O points are to distance and the O points of remote arc one end end points of the first side straightway to air-inlet grille 3 the
The difference of the distance between end points is L1 in side, the distance and O of remote arc one end end points of O points to the second side straightway
The difference of point to the distance between end points in the side of air-inlet grille 3 second is L2, wherein L2 ＞ L1.Due to the air intake of through-flow fan blade 1
The air velocity of the place side of heat exchanger 4 of mouth institute direction is larger, and air requirements amount is larger, therefore can exceed heat exchanger 4
The length of air-inlet grille 3 is bigger, so as to increase the heat exchange area of heat exchanger 4 so that the air of the side enters through air-inlet grille 3
Behind region between air-inlet grille 3 and heat exchanger 4, it can quickly be distributed to the surface of heat exchanger 4 of the side, be carried out with heat exchanger 4
Fully entered after heat exchange in through-flow fan blade 1.Because the heat exchanger 4 of the side exceeds into style relative to the heat exchanger of opposite side
The incoming air area of grid 3 is bigger, therefore even if air velocity is higher, can also ensure the intake by heat exchanger 4, and cause
Between the air air intake and heat exchanger 4 of the side can abundant contact heat-exchanging, improve heat exchange efficiency.
Preferably, L2 and L1 difference arrives 40mm for 20.
Preferably, L2 and L1 difference is 35mm.
Preferably, air channel 2 has air outlet 5, and air outlet 5 includes the first training wall 6 and the second training wall 7, in through-flow wind

Air outlet 5 has air intake and outlet air end, and wherein first training wall 6 at the center of through-flow fan blade 1 and air channel is interior
The distance of side top edge determines the inner side of the air-out length in air channel 2, the center of through-flow fan blade 1 and second training wall 7 in air channel
The distance of lower edge determines the air intake position of air outlet duct, and both are combined, in that case it can be decided that the air supplying distance of air channel structure,
The distance between i.e. from the air intake position of air outlet duct to air-out position, by by L1/L2 scope be defined to 1.59 to
2.03, the air supplying distance of air channel structure can be rationally limited with the spacing of both by the center of through-flow fan blade so that air channel
Structure can be associated with the diameter of through-flow fan blade, can either have enough air supplying distances, and and can enough provides enough air-out
Intensity so that the air exhausting structure of air-conditioning is more reasonable, while the wind noise of air conditioner can also be made to obtain certain control, from
And make it that the air-out of air-conditioning is more uniform, air-out effect is more preferable.
According to an embodiment of the invention, air-conditioning system includes indoor set, and the indoor set is above-mentioned indoor set.
