Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, air-conditioner of the present invention is further elaborated.Should be appreciated that specific embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
Referring to figs. 1 through Fig. 6, air-conditioner one embodiment of the present invention comprises housing, fan assembly, heat exchanger 6 and is arranged on the noise reduction assembly 8 at air outlet place, housing is for holding fan assembly, heat exchanger 6 and noise reduction assembly 8, noise reduction assembly 8 comprises the acoustical panel 81 that two or more is longitudinally arranged, acoustical panel 81 is multi-fold structure, its shape of cross section is waveform, forms gas channel 82 between two adjacent acoustical panels 81.Acoustical panel 81 is preferably made up of metal material.
As shown in Figure 3, described housing comprises left plate 10, right plate 4, base plate 12, upper cover plate 5 and opening panel 9, wherein, base plate 12 is provided with blower fan base plate 13, fan assembly is arranged on motor fixing plate 3, is placed in the top of blower fan base plate 13, and motor fixing plate 3 is installed on the housing; Fan assembly comprises fan part 14, support 15, motor 16, centrifugation blade 1, front spiral case 2, rear spiral case 17 and chute 18, and heat exchanger 6 is arranged on left plate 10 and right plate 4 by fixed head 7, is placed in the top of water pan component 11.
During air-conditioner work, air intake direction is as shown in the direction of arrow in Fig. 2, air-flow (wind) enters described housing from centrifugation blade 1, noise reduction assembly 8 is entered after over-heat-exchanger 6 heats or cools, flow through the gas channel 82 between acoustical panel 81, carry out flowing out from the opening part of opening panel 9 after noise reduction process through noise reduction assembly 8.
More preferably, as a kind of embodiment, included angle A between adjacent two foldings of described acoustical panel 81 is 80 °-90 °, preferably, acoustical panel 81 is three foldings, as shown in Figure 5 and Figure 6, be respectively the first folding 811, second folding 812 and the 3rd folding 813, angle between first folding 811 and the second folding 812 is the first knuckle, angle between second folding 812 and the 3rd folding 813 is the second knuckle, on same cross section, two adjacent acoustical panels 81, the summit 815 of the summit 814 of the first knuckle of one of them acoustical panel 81 and the second knuckle of another acoustical panel 81 is on the horizontal line of same perpendicular to described housing.As shown in phantom in Figure 6, this dotted line perpendicular to opening panel 9, thus makes air-flow all just can send after noise reduction process to line between the summit 814 of the first knuckle and the summit 815 of the second knuckle, reduces wind noise.
More preferably, as a kind of embodiment, acoustical panel 81 is provided with quieter material (not shown), the inwall of described housing is also provided with quieter material (not shown), described quieter material be sponge, Sound-proof material or other can the material of sound-absorbing.Preferably, acoustical panel 81 is arranged multiple salient point or concave point (not shown).Quieter material plays insulation and reduces the effect of noise, and acoustical panel 81 arranges salient point or concave point also plays the effect reducing noise.
More preferably, as a kind of embodiment, the cross section of acoustical panel 81 is symmetrical structure, as shown in Figure 6, the cross section of acoustical panel 81 with the second folding 812 mid point for symmetrical centre.Preferably, two adjacent acoustical panels 81 be arranged in parallel, and the first knuckle is 80 °-90 °, and the second knuckle is also 80 °-90 °, and preferably the first knuckle is identical with the size of the second knuckle.
Included angle A between adjacent two foldings controls to be 80 °-90 ° to be the best according to the actual height H of complete machine, and experiment proves, included angle A value is less, and the resistance that noise reduction assembly produces is more obvious, and complete machine power obviously increases; A value is larger, and most of air-flow does not directly blow out through noise reduction, and erasure effect is not obvious.L is the distance between two adjacent acoustical panels 81, control L value makes the summit 815 of the summit 814 of the first knuckle of an acoustical panel 81 and the second knuckle of another acoustical panel 81 on the horizontal line of same perpendicular to described housing, reach the object that air-flow is all sent after noise reduction process, avoid fraction and directly send the problem causing increasing complete machine level of noise without noise reduction process.Under equal conditions, air-conditioner is installing the comparative test result before and after noise reduction assembly as following table:
As can be seen from the above table, more than 4dB (A) can be reduced, as 850m than noise before installation noise reduction assembly after noise reduction assembly installed by the air-conditioner of above embodiment
3/ h air quantity, the noise before noise reduction assembly installed by air-conditioner is about 39dB (A), and after installing noise reduction assembly, noise is about 35dB (A); After increase noise reduction assembly, the motor speed of air-conditioner is higher than the rotating speed of the air conditioner with blower and coiled tube motor not increasing noise reduction assembly, but goes out ventilation pressure loss impact not quite to complete machine.
In addition, common air-cooled ducted air conditioner of the prior art, for 850m3/h air quantity, the noise of common air conditioner with blower and coiled tube is about 40-42dB (A), and the noise from air conditioner of the present embodiment is 35-36dB (A), reduces noise result obvious.
Air-conditioner in above embodiment, its noise reduction modular construction is simple, and the acoustical panel of noise reduction assembly is arranged to waveform, significantly reduces the noise of complete machine; The fan assembly of air-conditioner can select the number of motor according to the actual requirements, centrifugal blower, cross flow fan all can use, heat exchanger can select special-shaped device or regular two devices according to project organization and refrigeration requirement, and after the wave of the acoustical panel of noise reduction assembly folding shape angle and number choose reasonable, reducing effect clearly.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
