Embodiment mode 1
Fig. 1 is a refrigerant circuit diagram of an air conditioner using an outdoor unit according to an embodiment.
An air conditioner 1 using the outdoor unit 2 according to embodiment 1 includes a refrigeration cycle circuit 10. The refrigeration cycle circuit 10 is configured by connecting a compressor 40, a four-way switching valve 11, an outdoor heat exchanger 12, an indoor heat exchanger 13, an expansion valve 14, and an expansion valve 15 by refrigerant pipes. The type of refrigerant circulating through the refrigeration cycle 10 is not limited.

The compressor 40 compresses a refrigerant. The compressor 40 includes a body portion 41, and the body portion 41 includes a compression mechanism portion that compresses a refrigerant. The main body 41 includes a container 42 as a closed container. The compression mechanism is housed in the container 42. Further, the compressor 40 includes a suction muffler 43 as a closed container. The suction muffler 43 separates the refrigerant flowing into the suction muffler 43 into a gaseous refrigerant and a liquid refrigerant. The outlet of the refrigerant of suction muffler 43 is connected to the inlet of the refrigerant of main body 41. Then, the gas refrigerant is supplied from the suction muffler 43 to the main body portion 41. The gaseous refrigerant is compressed in the compression mechanism of the body 41 and discharged from the body 41. That is, the inlet of the refrigerant of the suction muffler 43 is the suction port of the refrigerant of the compressor 40. The outlet of the refrigerant of the body 41, in other words, the outlet of the refrigerant of the container 42 is a discharge port of the refrigerant of the compressor 40.
In the following, a refrigerant pipe connected to a refrigerant suction port of the compressor 40 is referred to as a suction pipe 18.

The four-way switching valve 11 is connected to a refrigerant suction port of the compressor 40, a refrigerant discharge port of the compressor 40, the outdoor heat exchanger 12, and the indoor heat exchanger 13. The four-way switching valve 11 switches the connection destination of the refrigerant discharge port of the compressor 40 to the outdoor heat exchanger 12 or the indoor heat exchanger 13. In other words, the four-way switching valve 11 switches the connection destination of the refrigerant suction port of the compressor 40 to the outdoor heat exchanger 12 or the indoor heat exchanger 13.
The outdoor heat exchanger 12 functions as an evaporator during the heating operation and functions as a condenser during the cooling operation. In embodiment 1, a fan 21 is provided in the vicinity of the outdoor heat exchanger 12. The fan 21 supplies outdoor air, which is a heat exchange target of the refrigerant flowing through the outdoor heat exchanger 12, to the outdoor heat exchanger 12. The fan 21 is driven by a motor 22. The indoor heat exchanger 13 functions as a condenser during the heating operation and functions as an evaporator during the cooling operation. The expansion valve 14 is provided in a refrigerant pipe connecting the outdoor heat exchanger 12 and the indoor heat exchanger 13, and regulates the flow rate of the refrigerant flowing through the outdoor heat exchanger 12. The expansion valve 15 is provided on the side of the indoor heat exchanger 13 with respect to the expansion valve 14 in a refrigerant pipe connecting the outdoor heat exchanger 12 and the indoor heat exchanger 13, and adjusts the flow rate of the refrigerant flowing through the indoor heat exchanger 13.

The temperature sensor 35 detects the temperature of the refrigerant flowing between the expansion valve 15 and the indoor heat exchanger 13. The temperature sensor 36 detects the temperature of the refrigerant flowing through the indoor heat exchanger 13. The temperature sensor 37 detects the temperature of the indoor air supplied to the indoor heat exchanger 13. The control device 38 controls the driving frequency of the compression mechanism of the compressor 40, the rotation speed of the fan 21, the opening degree of the expansion valve 14, the opening degree of the expansion valve 15, and the like based on the detection values of these sensors.
The above-described respective configurations constituting the air conditioner 1 are housed in the outdoor unit 2 or the indoor unit 3. Specifically, the outdoor unit 2 houses a four-way switching valve 11, an outdoor heat exchanger 12, an expansion valve 14, a fan 21, a motor 22, a pressure sensor 31, a pressure sensor 32, a temperature sensor 33, a temperature sensor 34, a controller 38, and a compressor 40.

These indoor units 3 are connected in parallel to the outdoor unit 2.
Fig. 2 is a perspective view of the outdoor unit according to embodiment 1, as viewed from the front right side. Fig. 3 is a perspective view of the outdoor unit according to embodiment 1 as viewed from the front right side, and is a view of the outdoor unit with the top surface portion, the front surface portion, the left side surface portion, the right side surface portion, and the back surface portion of the outer shell portion removed.
The outdoor unit 2 includes, for example, a substantially rectangular parallelepiped outer shell portion 50. The outer frame portion 50 is provided with a plurality of grips 59 to be gripped by an operator when moving the outdoor unit 2. The configuration of the outer shell 50 is not particularly limited, but in embodiment 1, the outer shell 50 is configured by a top panel 51, a base 52, a front panel 53, a maintenance panel 54, a right side panel 55, a left side panel 56, a cover panel 57, and a cover panel 58.
The top panel 51 constitutes a top surface portion of the outline portion 50. The base 52 constitutes a bottom surface portion of the outline portion 50. The front panel 53 constitutes a left side portion of the front surface portion of the outline portion 50. The maintenance panel 54 constitutes an upper portion on the right side of the front surface portion of the housing 50 and an upper portion on the front side of the right side surface portion of the housing 50. Right side panel 55 constitutes an upper portion on the rear side of the right side surface of outer shell 50 and an upper portion on the right side of the rear surface of outer shell 50. The left side panel 56 constitutes a left side portion of the outer shell 50. Cover panel 57 constitutes a lower portion on the right side of the front surface portion of outline 50 and a lower portion on the front side of the right side surface portion of outline 50. Cover panel 58 constitutes a lower portion on the rear side of the right side surface portion of outline 50 and a lower portion on the right side of the back surface portion of outline 50.
The interior of the outer shell 50 is divided by a partition 60 into a blower chamber 61 and a machine chamber 62. The outdoor heat exchanger 12 is housed in the blower chamber 61. Although not shown in fig. 3, the fan 21 and the motor 22 are also housed in the blower chamber 61. In addition, the machine room 62 accommodates the compressor 40.
Conventionally, when an operation of an air conditioner is started and a compressor is driven, the compressor vibrates. In addition, noise may be generated by vibration of the compressor. Therefore, some conventional air conditioners include a sound insulating member surrounding the compressor. The air conditioner 1 according to embodiment 1 also includes a sound insulating member 70 surrounding the periphery of the compressor 40. The sound insulating member 70 has the same structure as a conventional sound insulating member. For example, the sound insulating member 70 is configured as follows.
Fig. 4 is a side view of the periphery of the compressor of the outdoor unit according to embodiment 1. In fig. 4, the soundproof member 70 is shown in cross section.
The compressor 40 is surrounded by the soundproof member 70 at the side and above. The sound insulating member 70 includes a rubber portion 71 formed of rubber and constituting an outer shell portion. That is, the rubber portion 71 has rigidity that can maintain the shape of the outline portion, and has sound insulation properties. The sound insulating member 70 is provided with a nonwoven fabric 72 on the inner peripheral surface of the rubber portion 71, in other words, on the surface of the rubber portion 71 facing the compressor 40. The nonwoven fabric 72 has a sound absorbing effect.
Here, conventionally, when the compressor vibrates, the refrigerant pipe connected to the compressor also vibrates. Therefore, vibration of the compressor may be transmitted to the entire outdoor unit through a refrigerant pipe connected to the compressor, thereby generating noise. Therefore, in the conventional outdoor unit of an air conditioner, the vibration reduction member described in patent document 1 is wound around a horizontally extending portion of the refrigerant pipe connected to the compressor, thereby reducing vibration of the refrigerant pipe connected to the compressor. However, there is a lack of space around the compressor housed in the outdoor unit. Therefore, it may be difficult to wind the vibration damping member around a horizontally extending portion of the refrigerant pipe connected to the compressor. Therefore, the conventional outdoor unit of an air conditioner may have the following configurations: in the case where the space around the compressor is short, the vibration of the refrigerant pipe connected to the compressor cannot be reduced.
Therefore, the outdoor unit 2 according to embodiment 1 includes the 1 st vibration damping member 80.
Fig. 5 is a view of the periphery of the compressor of the outdoor unit according to embodiment 1, as viewed from above. The first damping member 80 will be described below with reference to fig. 4 and 5.
The 1 st damping member 80 is formed of rubber used in conventional damping members such as butyl rubber. The 1 st damping member 80 has a 1 st through hole 81 that penetrates in the vertical direction. The suction pipe 18 is inserted into the 1 st through hole 81 so that the outer peripheral surface of the suction pipe 18 contacts the inner peripheral surface of the 1 st through hole 81. The 1 st vibration damping member 80 is fixed to the upper portion of the suction muffler 43 as a closed container. The fixing method of the 1 st vibration damping member 80 and the suction muffler 43 is not particularly limited. For example, the 1 st vibration damping member 80 is fixed to the upper portion of the suction muffler 43 by a double-sided tape, a paste, an adhesive, or the like.
The 1 st vibration damping member 80 configured as described above can be provided in the suction pipe 18 even when a conventional vibration damping member cannot be provided in the suction pipe 18. That is, the 1 st vibration damping member 80 configured as described above can reduce the vibration of the suction pipe 18 even when the conventional vibration damping member cannot be provided in the suction pipe 18, and can reduce the noise generated by the vibration of the compressor 40 transmitted to the entire outdoor unit 2.
Further, the conventional damper member requires a holding member for preventing the damper member from falling. On the other hand, the 1 st damping member 80 according to embodiment 1 does not require a holding member required for a conventional damping member. Therefore, by using the 1 st vibration damping member 80, noise can be reduced more inexpensively than in the related art.
Further, since the 1 st vibration damping member 80 according to embodiment 1 is fixed to the upper portion of the suction muffler 43, vibration of the suction muffler 43 can be suppressed. Therefore, the 1 st vibration damping member 80 according to embodiment 1 can suppress vibration of the compressor 40 more than the conventional vibration damping member. That is, the 1 st vibration damping member 80 according to embodiment 1 can reduce noise generated by transmission of vibration of the compressor 40 to the entire outdoor unit 2, as compared with a conventional vibration damping member.
In addition, conventionally, a refrigerant pipe is connected to a compressor, and therefore the center of gravity of the compressor is shifted, which may increase vibration of the compressor. Further, when the center of gravity of the compressor moves, the moving area of the compressor changes when the compressor vibrates. Further, since the movable region of the compressor is changed, the refrigerant pipe connected to the compressor may come into contact with the sound insulating member surrounding the compressor, thereby generating noise. In contrast, by fixing the 1 st vibration damping member 80 according to embodiment 1 to the suction muffler 43, the center of gravity of the compressor 40 can be moved. Therefore, the center of gravity of the compressor 40 after the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40 can be moved to the vicinity of the position of the center of gravity of the compressor 40 before the connection to the suction pipe 18 and the discharge pipe 19. Therefore, by using the 1 st vibration damping member 80 according to embodiment 1, it is possible to suppress noise generated by the movement of the center of gravity of the compressor 40.
In addition, the 1 st damping member 80 according to embodiment 1 is formed with a notch 82 formed by cutting a gap between the outer peripheral surface of the 1 st damping member 80 and the inner peripheral surface of the 1 st through hole 81. By forming the notch 82 in the 1 st damping member 80, the suction pipe 18 can be inserted into the 1 st through hole 81 from the lateral direction, and the 1 st damping member 80 can be easily attached.
The 1 st vibration damping member 80 may be provided to the body portion 41 of the compressor 40. Specifically, the discharge pipe 19 may be inserted into the 1 st through hole 81 so that the outer peripheral surface of the discharge pipe 19 contacts the inner peripheral surface of the 1 st through hole 81. The 1 st vibration damping member 80 may be fixed to the upper portion of the container 42, which is the main body 41 of the closed container. Accordingly, even when the conventional vibration damping member cannot be provided in the discharge pipe 19, the vibration of the discharge pipe 19 can be reduced, and the noise generated by the vibration of the compressor 40 transmitted to the entire outdoor unit 2 can be reduced.
Further, by providing the 1 st vibration damping member 80 above the container 42 of the body 41, noise can be reduced more inexpensively than in the related art. Further, since the vibration of the main body portion 41 of the compressor 40 can be suppressed by providing the 1 st vibration damping member 80 above the container 42 of the main body portion 41, noise generated by the transmission of the vibration of the compressor 40 to the entire outdoor unit 2 can be further reduced as compared with a conventional vibration damping member. Further, by providing the 1 st vibration damping member 80 above the container 42 of the body 41, an effect of suppressing noise caused by the movement of the center of gravity of the compressor 40 can be obtained.
As described above, the outdoor unit 2 of the air conditioner 1 according to embodiment 1 includes the compressor 40, the refrigerant pipe, and the 1 st vibration damping member 80. The compressor 40 includes a closed container. The refrigerant pipe extends in the vertical direction and is connected to an upper portion of the closed casing of the compressor 40. The 1 st damping member 80 has a 1 st through hole 81 that penetrates in the vertical direction. The 1 st vibration damping member 80 is fixed to the upper portion of the closed casing of the compressor 40 by inserting a refrigerant pipe connected to the upper portion of the closed casing into the 1 st through hole 81.
Since the outdoor unit 2 according to embodiment 1 includes the 1 st vibration damping member 80, it is possible to reduce vibration of the refrigerant pipe connected to the compressor 40 even when a conventional vibration damping member cannot be provided as described above.
Embodiment mode 2
When the vibration of the refrigerant pipe cannot be sufficiently reduced by only the weight of the 1 st vibration damping member 80, the following 2 nd vibration damping member 90 may be added. Note that in embodiment 2, items not described in particular are the same as those in embodiment 1, and the same functions and configurations as those in embodiment 1 are described using the same reference numerals.
Fig. 6 is a side view of the periphery of the compressor of the outdoor unit according to embodiment 2. Fig. 7 is a view of the periphery of the compressor of the outdoor unit according to embodiment 2, as viewed from above. In fig. 6, the sound insulating member 70, the 1 st vibration damping member 80, and the 2 nd vibration damping member 90 are shown in cross section.
The outdoor unit 2 according to embodiment 2 includes at least one 2 nd vibration damping member 90 in addition to the configuration described in embodiment 1. The 2 nd damping member 90 is made of rubber used in conventional damping members such as butyl rubber. The 2 nd damping member 90 has a 2 nd through hole 91 penetrating in the vertical direction. The suction pipe 18 is inserted into the 2 nd through hole 91 such that the outer peripheral surface of the suction pipe 18 contacts the inner peripheral surface of the 2 nd through hole 91. The 2 nd damping member 90 is disposed above the 1 st damping member 80. The 2 nd damping member 90 is fixed to the 1 st damping member 80, for example. For example, double-sided tape, paste, or an adhesive is used to fix the second damping member 90.
In fig. 6 and 7, the outdoor unit 2 including only one 2 nd vibration damping member 90 is shown, but the outdoor unit 2 may include a plurality of 2 nd vibration damping members 90. In this case, a plurality of 2 nd damping members 90 fixed side by side in the vertical direction may be disposed above the 1 st damping member 80.
The outdoor unit 2 includes the 2 nd vibration damping member 90 in addition to the 1 st vibration damping member 80, and thus the weight of the vibration damping member attached to the suction pipe 18 can be increased as compared with a case where only the suction pipe 18 is attached to the suction pipe 18. Therefore, when the vibration of the suction pipe 18 cannot be sufficiently reduced only by the weight of the 1 st vibration damping member 80, the vibration of the suction pipe 18 can be reduced by providing the outdoor unit 2 with the 2 nd vibration damping member 90 in addition to the 1 st vibration damping member 80.
As shown in fig. 7, the 2 nd damping member 90 is preferably formed with a notch 92 formed by cutting between the outer peripheral surface of the 2 nd damping member 90 and the inner peripheral surface of the 2 nd through hole 91. By forming the notch 92 in the 2 nd damper member 90, the suction pipe 18 is inserted into the 2 nd through hole 91 from the lateral direction, and the 2 nd damper member 90 can be easily attached.
As shown in fig. 6 and 7, a recess 93 is preferably formed in the 2 nd damping member 90 adjacent to the 1 st damping member 80 in the vertical direction. Specifically, when the 2 nd damping member 90 adjacent to the 1 st damping member 80 in the vertical direction is viewed from above, the 2 nd damping member 90 is larger than the 1 st damping member 80. Further, a recess 93 for accommodating the 1 st vibration damping member 80 disposed below is formed in the 2 nd vibration damping member 90 adjacent to the 1 st vibration damping member 80 in the vertical direction.
By forming the recess 93 in the 2 nd damping member 90, the 2 nd damping member 90 can be fixed to both the 1 st damping member 80 and the suction muffler 43. Therefore, for example, in the case where the 2 nd vibration damping member 90 is formed of a material that is not easily adhered to the 1 st vibration damping member 80, the 2 nd vibration damping member 90 can be firmly fixed by fixing the 2 nd vibration damping member 90 to the suction muffler 43. For example, when the 2 nd vibration damping member 90 is formed of a material that is not easily adhered to the suction muffler 43, the 2 nd vibration damping member 90 can be firmly fixed by fixing the 2 nd vibration damping member 90 to the 1 st vibration damping member 80. Therefore, by forming the concave portion 93 in the 2 nd damping member 90, the width of selecting the material of the 2 nd damping member 90 is increased, and the degree of freedom in designing the outdoor unit 2 is improved.
When the 1 st damper member 80 is attached to the discharge pipe 19, the 2 nd damper member 90 may be disposed above the 1 st damper member 80.
Embodiment 3
In embodiments 1 and 2, when the 1 st damping member 80 is viewed from above, the center of the 1 st through hole 81 is the center of gravity of the 1 st damping member 80. In this case, by mounting the 1 st vibration damping member 80 to the compressor 40, the center of gravity of the compressor 40 can be moved in the direction in which the main body portion 41 and the suction muffler 43 are arranged in the parallel direction in a plan view. When the center of gravity of the compressor 40 is moved in a direction different from the direction in which the main body portion 41 and the suction muffler 43 are arranged in parallel in a plan view, the first vibration damping member 80 may be configured as in embodiment 3. Note that in embodiment 3, items not described in particular are the same as those in embodiment 1 or embodiment 2, and the same functions and configurations as those in embodiment 1 or embodiment 2 are described using the same reference numerals. In the following, an example in which the 1 st vibration damping member 80 is attached to the suction pipe 18 will be described.
Fig. 8 is a view of the periphery of the compressor of the outdoor unit according to embodiment 3, as viewed from above.
In embodiment 3, when the 1 st damping member 80 is viewed from above, the center of the 1 st through hole 81 is disposed at a position different from the center of gravity of the 1 st damping member 80. By configuring the 1 st damping member 80 in this manner, the center of gravity of the compressor 40 can be moved in a direction in which the center of the 1 st through hole 81 and the center of gravity of the 1 st damping member 80 are aligned in a plan view. In the case of fig. 8, the center of gravity of compressor 40 can be moved in a direction perpendicular to the direction in which main body 41 and suction muffler 43 are aligned in plan view.
When the center of gravity of the compressor 40 is shifted in a direction different from the direction in which the main body portion 41 and the suction muffler 43 are arranged in parallel in a plan view after the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40, the use of the first vibration damping member 80 shown in embodiment 3 can suppress noise generated by the shift of the center of gravity of the compressor 40.
In the case where the outdoor unit 2 includes the 2 nd damping member 90, the center of the 2 nd through hole 91 may be disposed at a position different from the center of gravity of the 2 nd damping member 90 when the 2 nd damping member 90 is viewed from above. When the center of gravity of the compressor 40 is shifted in a direction different from the direction in which the main body portion 41 and the suction muffler 43 are arranged in parallel in a plan view after the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40, the 2 nd vibration damping member 90 configured as described above is used, whereby noise generated by the shift of the center of gravity of the compressor 40 can be suppressed.
Here, when the center of the 1 st through hole 81 is disposed at a position different from the center of gravity of the 1 st vibration damping member 80 when the 1 st vibration damping member 80 is viewed from above, the mounting angle of the 1 st vibration damping member 80 to the suction pipe 18 is limited. Therefore, when the notch 82 is formed in the 1 st damping member 80, the notch 82 is preferably formed at a position where the operator can press the 1 st damping member 80 and insert the suction pipe 18 into the 1 st through hole 81. Thus, the operator can attach the 1 st vibration damping member 80 without rotating his or her hand to the side facing the suction pipe 18. Therefore, the 1 st damping member 80 is easily mounted.
