Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an exhaust pipe structure of an air conditioning compressor and an exhaust pipe assembly installation structure. Background Art

[0002] When the variable frequency air conditioner is in operation, the more frequency points the compressor operates at, the more accurate the air conditioner temperature control precision will be, and the better the comfort will be.

[0003] The pipeline vibration of the air conditioning system is mainly the vibration of the compressor exhaust pipe. The compressor exhaust pipe is in a forced vibration state due to the excitation of the compressor, which may cause stress concentration and excessive stress. In severe cases, it will cause the compressor exhaust pipe to break. The fundamental reason that specifically affects the vibration of the air conditioning compressor exhaust pipe is its natural frequency. When the compressor operating frequency is consistent with the natural frequency of the compressor exhaust pipe, resonance will occur, increasing the vibration of the compressor exhaust pipe. The natural frequency of the existing compressor exhaust pipe is close to and densely distributed with the low-frequency (10-40Hz) operating frequency of the compressor of the variable frequency air conditioner. In addition, the low-frequency speed fluctuation of the air conditioner compressor at low frequency (10-40Hz) is large, which makes the compressor exhaust pipe vibrate more when the compressor is running at low frequency (10-40Hz). In order to reduce the impact of the compressor on the exhaust pipe when it is running at low frequency (10-40Hz), the compressor frequency hopping process is generally adopted, which leads to a limited number of low-frequency operating frequency points of the compressor, thereby affecting the temperature control accuracy of the air conditioner and the comfort of the air conditioner. Moreover, the larger exhaust pipe vibration will produce a larger noise in the room, affecting the user's experience. Summary of the invention

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] The following parts are located in Figure 1 The orientation of the components shown is for reference only.

[0030] like Figures 1 to 5 As shown, the exhaust pipe structure of the air-conditioning compressor comprises a pipe body 1, one end of the pipe body 1 is an inlet end 2, and the other end is an outlet end 3, and the pipe body 1 comprises a first vertical straight pipe section 4, a first curved pipe section 5, a first oblique straight pipe section 6, a second curved pipe section 7, a second oblique straight pipe section 8, a third curved pipe section 9, a second vertical straight pipe section 10, a third vertical straight pipe section 11, a fourth curved pipe section 12, a fourth vertical straight pipe section 13, a fifth curved pipe section 14, a third oblique straight pipe section 15, a sixth curved pipe section 16, a fifth vertical straight pipe section 17, a seventh curved pipe section 18, a fourth oblique straight pipe section 19, an eighth curved pipe section 20, and a horizontal straight pipe section 21 in sequence from the inlet end 2 to the outlet end 3, the lower end of the first vertical straight pipe section 4 is the inlet end 2, and the rear end of the horizontal straight pipe section 21 is the outlet end 3.

[0031] The cross-sectional shape of the pipe body 1 is circular. The vertical straight pipe section indicates that the direction of the corresponding straight pipe section is vertically arranged, wherein the axis is a vertical straight line. The oblique straight pipe section indicates that the direction of the corresponding straight pipe section is inclined, and the oblique straight pipe section has a certain angle with the vertical plane and the horizontal plane. The direction of the horizontal straight pipe section 21 is horizontally arranged, wherein the axis is on the horizontal plane.

[0032] Among them, Figure 2 As shown, the first oblique straight pipe section 6 is located on the right side of the first vertical straight pipe section 4, and the angle formed by the central axis of the first vertical straight pipe section 4 and the central axis of the first oblique straight pipe section 6 is α, and α is preferably 80°≤α≤120°; the second oblique straight pipe section 8 is located on the lower side of the first oblique straight pipe section 6, and the angle formed by the central axis of the first oblique straight pipe section 6 and the central axis of the second oblique straight pipe section 8 is β, and β is preferably 60°≤β≤90°.

[0033] For example Figure 3 As shown, the second vertical straight pipe section 10 is located on the left side of the second oblique straight pipe section 8, the third vertical straight pipe section 11 is located on the lower side of the second vertical straight pipe section 10, and the shape formed by the third vertical straight pipe section 11, the fourth curved pipe section 12, and the fourth vertical straight pipe section 13 is U-shaped; the third oblique straight pipe section 15 is located on the right side of the fourth vertical straight pipe section 13, and the angle formed by the central axis of the fourth vertical straight pipe section 13 and the central axis of the third oblique straight pipe section 15 is γ, and γ is preferably 120°≤γ≤150°; the fifth vertical ... third oblique straight pipe section 15 is γ, and γ is preferably 120°≤γ≤150°; the fifth vertical straight pipe section 15 is located on the right side of the fourth vertical straight pipe section 13, and the angle formed by the central axis of the fourth vertical straight pipe section 13 and the third oblique straight pipe section 15 is γ, and γ is preferably 120°≤γ≤150°; the fifth vertical straight pipe section 15 is located on the right side of the fourth vertical straight pipe section 13, and the angle formed by the central axis of the fourth vertical straight pipe section 13 and the third oblique straight pipe section 15 is γ, and γ is preferably 120°≤γ≤150°; the fifth vertical straight pipe section 15 is located on the right side of the fourth vertical straight pipe section Section 17 is located on the right side of the third oblique straight pipe section 15, and the angle formed by the central axis of the third oblique straight pipe section 15 and the central axis of the fifth vertical straight pipe section 17 is δ, and δ is preferably 120°≤δ≤150°; the fourth oblique straight pipe section 19 is located on the left side of the fifth vertical straight pipe section 17, and the angle formed by the central axis of the fifth vertical straight pipe section 17 and the central axis of the fourth oblique straight pipe section 19 is λ, and λ is preferably 130°≤λ≤170°; the horizontal straight pipe section 21 is located on the left side of the fourth oblique straight pipe section 19.

[0034] The fundamental reason that affects the structure of the exhaust pipe of the air conditioner compressor is its natural frequency. When the operating frequency of the compressor 22 is consistent with the natural frequency of the compressor exhaust pipe structure, resonance will occur. The factors that affect the natural frequency of the compressor exhaust pipe structure are mainly its mass and rigidity. For the compressor exhaust pipe structure, the main factors that affect its rigidity are the direction of each pipe section and the bending angle of each pipe section. Therefore, a reasonable direction of each pipe section and a reasonable bending angle can reduce the vibration of the exhaust pipe structure, reduce the stress at the bend of the exhaust pipe, and improve the reliability of the exhaust pipe.

[0035] Since the inlet end 2 is detachably connected to the vertical straight pipe section 24 of the exhaust port of the compressor 22, the first vertical straight pipe section 4, the first curved pipe section 5, the first oblique straight pipe section 6, the second curved pipe section 7, the second oblique straight pipe section 8, the third curved pipe section 9, and the second vertical straight pipe section 10 are arranged closer to the compressor 22, so the first vertical straight pipe section 4, the first curved pipe section 5, the first oblique straight pipe section 6, the second curved pipe section 7, the second oblique straight pipe section 8, the third curved pipe section 9, and the second vertical straight pipe section 10 are the main vibration absorbing parts, especially the first curved pipe section 5, the second curved pipe section 7, the third curved pipe section 9, the first vertical straight pipe section 4, the first curved pipe section 5, the first oblique straight pipe section 6, the second curved pipe section 7, the second oblique straight pipe section 8, the third curved pipe section 9, and the second vertical straight pipe section 10 have special structural shapes. The shape and direction can greatly increase the vibration absorption capacity of vibrations in different directions. Of course, other components constituting the tube body 1 also have certain vibration absorption capacity, such as the third oblique straight tube section 15, the fifth vertical straight tube section 17, and the fourth oblique straight tube section 19 forming a trapezoidal structure from bottom to top, which can effectively reduce the vibration of the tube body 1 and transmit it to the four-way valve 23; therefore, by adopting the tube body 1 with a specific structural shape and direction, the vibration of the exhaust pipe when the compressor 22 is running can be greatly reduced, and the possibility of excessive stress concentration in the exhaust pipe is reduced. The operating frequency points of the compressor 22 are increased, thereby improving the temperature control accuracy of the air conditioner, and thus greatly improving the comfort of the air conditioner; moreover, it can also significantly reduce the noise generated when the compressor is running, and improve the user experience. In order to ensure and improve the vibration absorption capacity of each bend section, and also to facilitate processing, the shapes of the first bend section 5, the second bend section 7, the third bend section 9, the fourth bend section 12, the fifth bend section 14, the sixth bend section 16, the seventh bend section 18, and the eighth bend section 20 are all arc-shaped.

[0036] More specifically, the overall processing of the pipe body 1 is relatively difficult and has high processing requirements, so the first vertical straight pipe section 4, the first curved pipe section 5, the first oblique straight pipe section 6, the second curved pipe section 7, the second oblique straight pipe section 8, the third curved pipe section 9, and the second vertical straight pipe section 10 are an integrated structure. The third vertical straight pipe section 11, the fourth curved pipe section 12, the fourth vertical straight pipe section 13, the fifth curved pipe section 14, the third oblique straight pipe section 15, the sixth curved pipe section 16, the fifth vertical straight pipe section 17, the seventh curved pipe section 18, the fourth oblique straight pipe section 19, the eighth curved pipe section 20, and the horizontal straight pipe section 21 are an integrated structure. After the two integrated structures are processed separately, they are connected by connecting pieces, and when in use, when one part is damaged, only the corresponding part needs to be replaced, without replacing the entire pipe body 1, thereby reducing the use cost. In order to further reduce the noise generated by the entire pipe body 1, especially the medium and high frequency noise problems caused by refrigerant pressure pulsation, the present invention is also provided with a silencer 27, the upper end of the silencer 27 is detachably connected to the lower end of the second vertical straight pipe section 10, and the lower end of the silencer 27 is detachably connected to the upper end of the third vertical straight pipe section 11.

[0037] Each pipe section of the present invention can gradually absorb the vibration energy transmitted from the compressor 22, thereby weakening the vibration of the four-way valve 23, thereby reducing the noise of the entire air-conditioning system.

[0038] In addition, Figure 4 As shown, the present invention also provides an air-conditioning compressor exhaust pipe assembly installation structure, including a compressor 22, a four-way valve 23, and also the above-mentioned air-conditioning compressor exhaust pipe structure, the compressor 22 is placed vertically, the four-way valve 23 is placed horizontally, the inlet end 2 is detachably connected to the vertical straight pipe section 24 of the exhaust port of the compressor 22, and the outlet end 3 is detachably connected to the connecting pipe section 25 of the four-way valve 23.

[0039] It can be seen that the stress structure of the exhaust pipe structure can be approximated as a cantilever beam stress structure, in which the outlet end 3 and the inlet end 2 of the exhaust pipe are fixed ends, and the remaining pipe sections are free ends. For cantilever beam vibration systems with different spans, the amplitude of the free end cannot directly measure the fatigue strength and reliability of the vibration system, while the stress and strain of the fixed end can directly and accurately evaluate the fatigue strength and reliability of the vibration system. Therefore, the stress value at the corresponding position on the exhaust pipe can be used to reflect its vibration, fatigue strength, etc.

[0040] Figure 5 It is a conventional air conditioner compressor exhaust pipe assembly installation structure in the prior art. When the compressor 22 operates at a frequency of 10-80 Hz and under the maximum cooling condition, a stress test is performed on the existing exhaust pipe 26. The test point is the outer side surface of the connection between the inlet end 2 of the existing exhaust pipe 26 and the exhaust port vertical straight pipe section 24. The stress data curve of the existing exhaust pipe 26 is as shown in FIG. Figure 6 as shown in .

[0041] When the compressor 22 operates at a frequency of 10-80 Hz and under the maximum refrigeration condition, the exhaust pipe of the present invention is subjected to a stress test using the exhaust pipe assembly mounting structure of the air conditioner compressor of the present invention. The test point is the outer side surface of the connection between the inlet end 2 of the pipe body 1 and the vertical straight pipe section 24 of the exhaust port, and a stress data curve of the exhaust pipe structure of the present invention is obtained. The stress data curve of the exhaust pipe structure of the present invention is shown in FIG. Figure 6 as shown in .

[0042] from Figure 6 It can be seen that if the stress is higher than the stress qualified judgment line, the stress exceeds the standard, indicating that the compressor 22 is not suitable for operation at this frequency point, and if the stress is lower than the stress qualified judgment line, the stress is qualified, indicating that the compressor 22 can operate at this frequency point. Figure 6It is concluded that the existing exhaust pipe 26 has excessive stress when the compressor is running at a low frequency (10-40Hz), while the exhaust pipe structure of the present invention has all qualified stresses when the compressor is running at a low frequency (10-40Hz) and does not have excessive stress. Therefore, the structure described in the present invention has a better vibration reduction effect than the structure of the prior art, and can meet the requirements of the compressor 22 to operate at all frequency points within its low frequency (10-40Hz) operating range.

[0043] The present invention provides an air-conditioning compressor exhaust pipe structure and an exhaust pipe assembly installation structure. By adopting an exhaust pipe structure with a specific structural shape and direction, the exhaust pipe structure has good quality and rigidity, can greatly reduce the vibration of the exhaust pipe when the compressor 22 is running at a low frequency (10-40Hz), and reduces the possibility of excessive stress concentration in the exhaust pipe; when the compressor 22 is running at a low frequency (10-40Hz), the stress of the exhaust pipe is within the allowable (qualified) stress, ensuring that the compressor 22 can operate at all frequency points within its low-frequency (10-40Hz) operating range. The operating frequency points of the compressor 22 are increased, the temperature control accuracy of the air conditioner is improved, and the comfort of the air conditioner is greatly improved; moreover, it can also significantly reduce the low-frequency noise caused by the vibration of the exhaust pipe when the compressor 22 is running, thereby improving the user experience.
