Further, air outlet gradually increases along the direction section away from fan installation plate.
Further, the angle of flare of air outlet is θ, wherein, 10 °≤θ≤20 °.
Further, air-cooled ducted air conditioner also includes heat exchanger, is arranged in the first cavity and is set relative to the roof inclination of housing Put.
Further, roof of the heat exchanger along housing extends to the bottom wall direction of housing and to close to the direction of air-supply arrangement Tilt.
Further, the angle of heat exchanger and roof is φ, wherein, 50 °≤φ≤80 °.
Further, present invention also offers a kind of air conditioner, including above-mentioned air-cooled ducted air conditioner.
Using the air-cooled ducted air conditioner of the present invention, by extending the air outlet length of air-supply arrangement, pass through fan installation plate and enter Enter into the first cavity, be favorably improved the air-out static pressure of air-supply arrangement, reduce wind speed, so as to reduce airflow kinetic energy loss, rise To the noise for reducing air-supply arrangement, the purpose of raising airduct engine efficiency.
Brief description of the drawings
The Figure of description for forming the part of the application is used for providing a further understanding of the present invention, and of the invention shows Meaning property embodiment and its illustrate be used for explain the present invention, do not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation according to air-cooled ducted air conditioner in the embodiment of the present invention;
Fig. 2 is the top view of Fig. 1 air-cooled ducted air conditioner;
Fig. 3 is the structural representation of the spiral case in Fig. 1.
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the embodiments of the invention provide a kind of air-cooled ducted air conditioner, including housing 10, the and of fan installation plate 20 Air-supply arrangement 30.Wherein, housing 10 is provided with the first cavity 11 and the second cavity 12.Fan installation plate 20 is arranged at housing 10 Inside, and the first cavity 11 is located at the first side of fan installation plate 20, the second cavity 12 is located at the second side of fan installation plate 20. Air-supply arrangement 30 is arranged in the second cavity 12, and air-supply arrangement 30 includes air outlet 31, and air outlet 31 is passed through by the second cavity 12 Fan installation plate 20 is placed in the first cavity 11.
By the length for the air outlet 31 for extending air-supply arrangement 30, pass through fan installation plate 20 and enter the first cavity In 11, the air-out static pressure of air-supply arrangement 30 is favorably improved, reduces wind speed, so as to reduce airflow kinetic energy loss, reduction is played and send The noise of wind apparatus 30, improve the purpose of airduct engine efficiency.
Because the wind speed of air-cooled ducted air conditioner air-out is higher, easily induces heat exchanger fin and produce pneumatic noise, thereby, it is ensured that air-out It is necessary to have enough spacing between mouth 31 and heat exchanger 40.But excessive spacing will cause unit oversized again, therefore air-out Between mouth 31 and heat exchanger 40 there is optimum value in spacing.As shown in figure 1, the distance between air outlet 31 and fan installation plate 20 are L1, the length of the first cavity is L, wherein, 0.05≤L1/L≤0.2。
Above-mentioned ratio is set in 0.05 to 0.2 in the range of this, it is ensured that the noise of air-supply arrangement is in minimum model Enclose, the efficiency of airduct is in optimum range.Preferably, L is worked as1The noise of air-supply arrangement is in minimum when/L takes median 0.125 Value, the efficiency of air-cooled ducted air conditioner are in maximum.
Air outlet 31 in the embodiment of the present invention gradually increases along the direction section away from fan installation plate 20.
Preferably, cutting is carried out to air outlet 31 along the direction away from fan installation plate 20, as shown in figure 3, air outlet 31 Two side where angle between straight line be air outlet 31 angle of flare.Further, the angle of flare of air outlet 31 is θ, its In, 10 °≤θ≤20 °.
Angle of flare θ is arranged to above-mentioned shape and angle, can suitably reduce wind speed, and then reduces airflow kinetic energy loss, Air-supply arrangement noise is reduced so as to reach, improves the purpose of airduct engine efficiency.
It should be noted that above-mentioned angle of flare θ is optimal effect when taking 15 ° of median.
As shown in Fig. 2 the air-cooled ducted air conditioner in the embodiment of the present invention also includes heat exchanger 40, simultaneously phase is arranged in the first cavity 11 It is obliquely installed for the roof of housing 10.Further, the angle of above-mentioned heat exchanger 40 and the roof of housing 10 is φ, wherein, 50°≤φ≤80°。
Heat exchanger 40 is arranged to oblique 1 word shape, so that it is relative with air outlet 31.Enable air-flow at air outlet 31 Heat exchanger 40 is enough flowed directly into, increases the contact area of air-flow and heat exchanger, improves heat transfer effect, reduces air-supply dress so as to reach The noise put, improve the purpose of the efficiency of air-cooled ducted air conditioner.
Preferably, when included angle takes 65 ° of median, the noise of air-supply arrangement is minimum, and it is maximum to improve airduct engine efficiency.
Air-cooled ducted air conditioner in the embodiment of the present invention also includes drip tray, is arranged in the first cavity 11, and is located at air outlet 31 With the lower section of heat exchanger 40, with collect the first cavity 11 in caused liquid.
