INVENTION TITLE: Structure and method for attenuating noise from outdoor unit of air conditioner The following statement is a full description of this invention, including the best method of performing it known to me/us:- BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an outdoor unit of an air conditioner, and more o particularly, to structure and method for attenuating noise from a compressor in an outdoor unit of an air conditioner.
Background of the Related Art 10 The air conditioner is provided with an indoor unit installed in a room for expanding and evaporating refrigerant, and an outdoor unit installed outside of the room for compressing and ii'" condensing the refrigerant, for cooling and heating the room. FIG. 1 illustrates a disassembled ego.
0o*o perspective view of the outdoor unit of a related art air conditioner.
S•Referring to FIG. 1, the outdoor unit is provided with a casing having a front panel 11, S.i a rear panel 12 and a base panel 13, and a fan 21, a motor 22, a heat exchanger 30 fitted in succession between the front panel 11 and the rear panel 12, and a compressor 51 and an accumulator 52 on other side of the base panel 13 partitioned by a noise barrier In the foregoing related art air compressor, the refrigerant compressed by the compressor 51 in the outdoor unit is provided to the heat exchanger 30, and heat exchanges with external air drawn by rotation of the fan 21, and transferred to the indoor unit, and the heat exchanged air is discharged through the front panel 11 of the casing. However, the outdoor unit of the air conditioner generates a loud noise as the compressor 51 compresses the refrigerant, and emits outside of the outdoor unit, that affects a quality of the air conditioner.
Accordingly, there have been many attempts to absorb the noise from the compressor 51 for reducing a noise of the outdoor unit. As a one of such methods, a sound absorbing/insulating material is surrounded around the compressor 51, and a sound absorbing material is fitted to the front panel 11 and the rear panel 12 for reducing a noise from the compressor 51 by means of the sound absorbing/insulating material, and further reducing the noise from the compressor 51 by :*means of the sound absorbing material.
:::However, in the related art, there have been no research for location, or material for an effective reduction of the noise from the compressor 51 in fitting the sound absorbing material to the front panel 11 and the rear panel 12. That is, it has been a mere fitting of the sound ooooo absorbing material to the front panel 11 and the rear panel 12 without taking a noise emission characteristics of the compressor into account, failing to shield the noise effectively and wasting a sound absorbing material.
15 SUMMARY OF THE INVENTION S"Accordingly, the present invention is directed to structure and method for attenuating noise from a compressor in an outdoor unit of an air conditioner that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide structure and method for attenuating noise from a compressor in an outdoor unit of an air conditioner, in which a noise from a compressor; which is a major source of noise in the outdoor unit, is absorbed more effectively, for minimizing required sound absorbing/insulating material and a sound absorbing material and attenuating the noise from the outdoor unit of the air conditioner to the maximum.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, the structure for attenuating noise from a S compressor in an outdoor unit of an air conditioner includes a casing having a rear panel with a suction grill for drawing external air, and a front panel with a discharge grill for discharging 10 drawn air, a fan in rear of the discharge grill in the casing for drawing the external air, a heat exchanger in rear of the fan for making heat exchange between the air drawn into the suction grill and a refrigerant, a sound absorbing material fitted to the front panel and the rear panel of the casing, a compressor and an accumulator coupled so that a noise is directed mostly to the front o~ panel and the rear panel having the sound absorbing material fitted thereto, sound o. 15 absorbing/insulating materials fitted to surround the compressor and the accumulator, and a o" sound barrier for partitioning a space the fan and the heat exchanger fitted therein, and a space the compressor fitted therein.
In another aspect of the present invention, there is provided a method for attenuating noise from a compressor in an outdoor unit of an air conditioner, the outdoor unit having a sound absorbing material fitted thereto, including the steps of fitting the sound absorbing material to a position of the casing where the fitting of the sound absorbing material thereto is the most convenient, and coupling the compressor and an accumulator so that a noise is directed toward the sound absorbing material.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention: In the drawings: FIG. 1 illustrates a disassembled perspective view of an outdoor unit of a related art air conditioner; .eoooi SFIG. 2 illustrates a disassembled perspective view of an outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention; FIG. 3 illustrates a horizontal section of an outdoor unit of an air conditioner in 15 accordance with a preferred embodiment of the present invention; FIG. 4 illustrates noise emission characteristics of a compressor; FIG. 5 illustrates an enlarged horizontal section of a compressor in an outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention; FIG. 6 illustrates a graph for comparing acoustic absorptivities of a fibrous material group sound absorbing material and a foam group sound absorbing material; and, FIG. 7 illustrates a graph showing noise levels of an outdoor unit of the present invention and the outdoor unit of the related art.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. FIG. 2 illustrates a disassembled perspective view of an outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention, and FIG. 3 illustrates a horizontal section of an outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention.
As shown, the outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention includes a casing 110 having a front panel 111 with a discharge grill 11 a for discharging inside air, a rear panel 112 with a suction grill 112a for drawing external air, and a base panel 113 forming a bottom ofthe casing 110. And, there are a fan 121 coupled with a motor 122 in rear of the discharge grill 111 a in the front panel 111 for oo I Sdrawing the external air, and a heat exchanger 130 between the motor 122 and the rear panel 112 for condensing the air drawn into the suction grill 112a. The casing 110 is partitioned by a noise barrier 140 from a space the fan 121, the motor 122, and the heat exchanger 130 fitted therein, 15 and the compressor 151 is fitted in a space(a right portion in FIG. 3) partitioned thus. And, the compressor 151 fitted with an accumulator 152 is fitted with sound absorbing/insulating material 161, and the front panel 111 and the rear panel 112 in front and rear of the compressor 151 are fitted with a sound absorbing material 162. And, the sound absorbing/insulating material around the compressor 151 and the accumulator 152, a combination of a sound absorbing material 161 a and a sound insulating material 161b, has the sound absorbing material 161a on an inside thereof and the sound insulating material on an outside thereof so that the sound absorbing material 161 a faces the compressor 151, the noise source. Particularly, in the present invention, the accumulator 152 is coupled with the compressor 151 such that a line drawn through centers of the compressor 151 and the accumulator 152 is substantially parallel to the front panel 111.
The reason why the compressor 151 and the accumulator 152 are coupled in above fashion will be explained. FIG. 4 illustrates noise emission characteristics of a compressor when a center frequency of the noise is 630 Hz and 3150 Hz and tested placing the compressor and the accumulator 152 parallel to Y-axis, wherein it can be known that the noise is emitted mostly in a direction vertical to a direction of coupling of the compressor 151 and the accumulator 152, i.e., in an X-axis direction. From this, it can be known that it is possible that the direction of emission of the noise from the compressor can be varied with an angle of coupling of the S compressor 151 and the accumulator 152. On the other hand, in view of a structure of the outdoor unit, the most suitable positions for fitting the sound absorbing material 162 for absorbing the noise from the compressor 151 are the front panel 111 and the rear panel 112. That is, the present invention suggests to couple the compressor 151 and the accumulator 152 such that the noise from the compressor 151 is emitted mostly toward the front panel 111 and the rear panel 112 by employing the foregoing noise emission characteristics. Accordingly, in the 15 foregoing outdoor unit of the present invention, the noise from the compressor 151 is emitted in i a direction substantially vertical to the front panel 111 and the rear panel 112 of the casing, and absorbed and insulated by the sound absorbing/insulating material 161 around the compressor 151 and the accumulator 152, primarily. And, the noise passed through the sound absorbing/insulating material 161 is absorbed and attenuated by the sound absorbing material 162 fitted to the front panel 111 and the rear panel 112.
In the meantime, FIG. 5 illustrates an enlarged horizontal section of a compressor in an outdoor unit of an air conditioner in accordance with a preferred embodiment of the present invention, wherein it is shown that the compressor 151 and the accumulator 152 are coupled such that the line drawn through centers of the compressor 151 and the accumulator 152 has an angle to an axis parallel to the front panel 111. As explained in the noise emission characteristics of the compressor, it is preferable that the coupling of the compressor 151 and the accumulator 152 is parallel to the front panel 111. However, if the angle between the line 'A' drawn through centers of the compressor 151 and the accumulator 152 and the axis parallel to the front panel 111 is not great excessively, as the noise from the compressor 151 is vertical to the front panel 111 and the rear panel 112 to some extent, the noise can be absorbed by the sound absorbing material 162 fitted to the front panel 111 and the rear panel 12, effectively. The 0 :0 angle is preferably below 300, and, at an angle greater than 30', the noise directed toward the side of the casing 110 is increased significantly, such that the noise from the compressor 151 may be absorbed, not by the sound absorbing material 162 effectively, but emitted outside of the ••ooo casing 110 through the side thereof.
000.
In the meantime, though FIG. 5 shows that the accumulator 152 is fitted to an inner side 0 of the casing 110 close to the front panel 111 centered on the compressor 151, it is apparent that, 15 as far as the line drawn through the centers of the compressor 151 and the accumulator 152 is at an angle below approx. 30' to the axis parallel to the front panel 111, the accumulator 152 may be fitted at an outer side close to the front panel 111, or inner or outer side centered on the compressor 151 close to the rear panel 112.
FIG. 6 illustrates a graph for comparing acoustic absorptivities of a fibrous material group sound absorbing material and a foam group sound absorbing material, wherein solid lines denote optimal values and dashed line denote measured values, wherefrom it can be known that the fibrous material group sound absorbing material has a better sound absorbing performance than the foam group sound absorbing material. Therefore, it is preferable that the fibrous material group sound absorbing material 162 which is thin and a good sound absorbing effect is employed as a material for fitting to the front panel 111 and the rear panel 112 of the casing.
FIG. 7 illustrates a graph showing noise levels of an outdoor unit of the present invention and the outdoor unit of the related art.
As shown, it can be known that the structure for attenuating noise from a compressor in an outdoor unit of an air conditioner of the present invention, in which the compressor 151 and the accumulator 152 are surrounded by the sound absorbing/insulating material 161 and the sound absorbing material 162 is fitted to the walls of the casing 110, shows positive noise 0 attenuation compared to the related art outdoor unit to which no sound absorbing material is fitted.
In the meantime, provided that the noise from the compressor 151 is made to be emitted ooooo toward the front panel 111 and the rear panel 112 of the casing and the sound absorbing material 162 is fitted even to a side of the casing 110 as well as the front panel 111 and the rear panel 112, the noise from the compressor 151 can be reduced, further.
15 A method for attenuating noise from a compressor in an outdoor unit of an air conditioner S"of the present invention will be explained.
In the method for attenuating noise from a compressor in an outdoor unit of an air conditioner of the present invention, the aforementioned compressor noise emission characteristics is utilized, such that a sound absorbing material 162 is fitted to a position inside of the casing 110 where fitting of the sound absorbing material thereto is the most convenient, and the compressor 151 and the accumulator 152 are coupled such that the noise is emitted mostly to the sound absorbing material. By the way, in the outdoor unit of the present invention, the most convenient position for fitting the sound absorbing material is the front panel 111 and the rear panel 112. Because other forms of the outdoor unit may have the most convenient position for fitting the sound absorbing material different from the same of the present invention, the sound absorbing material may be fitted to such position, and the compressor and the accumulator are fitted such that the noise from the compressor is emitted toward the sound absorbing material.
The present invention is applicable, not only to the outdoor unit of an air conditioner, but also to other appliances having a compressor and an accumulator in a casing, such as refrigerators.
i As has been explained, the structure and method for attenuating noise from a compressor in an outdoor unit of an air conditioner have the following advantages.
First, the fitting of a sound absorbing material in a direction the noise emitted the most according to the noise characteristics of a compressor permits an efficient attenuation of the noise from the outdoor unit of the air compressor.
S2 -Second, the effective fitting of the sound absorbing material prevents waste of the sound 15 absorbing material, thereby saving a production cost.
It will be apparent to those skilled in the art that various modifications and variations can be made in structure and method for attenuating noise from a compressor in an outdoor unit of an air conditioner of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
