The number N2 of the silencing holes in each group of the first silencing holes 101 may be determined according to the pipe diameter of the refrigerant pipe 11, or may be determined according to the type of the refrigerant and/or the refrigerant filling amount.

In this embodiment, the first silencing holes 101 are arranged according to the above manner, so that the first silencing holes 101 can be uniformly distributed on the wall of the refrigerant pipe 11, so that the refrigerant is uniformly dispersed after entering and exiting the first silencing holes 101, the uniform stability of the refrigerant after being regulated by the refrigerant regulating device 1 is further improved, and the noise in the refrigerant pipe 11 is further reduced.

For example, the number N1 of the plurality of sets of first sound deadening holes 101 may be 5 sets or 6 sets or 7 sets or 8 sets or 9 sets or 10 sets.

In this embodiment, too many groups of the first silencing holes 101 along the axial direction of the refrigerant pipe 11 can increase the refrigerant flow resistance to reduce the heat exchange efficiency of the air conditioner, and too few groups of the first silencing holes 101 along the axial direction of the refrigerant pipe 11 can not effectively reduce the pressure pulsation in the refrigerant, based on which the number of groups of the first silencing holes 101 along the axial direction of the refrigerant pipe 11 is between 5 groups and 10 groups, so that the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be effectively combined.

For example, the number N2 of the first sound deadening holes 101 in each group of the first sound deadening holes 101 may be 8 or 10 or 12 or 14 or the like.

In this embodiment, too many first silencing holes 101 along the circumferential direction of the refrigerant pipe 11 increase the flow resistance of the refrigerant, so as to reduce the heat exchange efficiency of the air conditioner, too many first silencing holes 101 along the circumferential direction of the refrigerant pipe 11 cannot effectively reduce the pressure pulsation in the refrigerant, and based on this, too many first silencing holes 101 along the circumferential direction of the refrigerant pipe 11 are 8 to 14, so that the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be effectively combined.

Further, in an embodiment, referring to fig. 2, the aperture D4 of the first sound-deadening hole 101 is not smaller than 0.3mm and not larger than 0.8mm.

For example, the aperture D4 of the first sound deadening hole 101 is 0.4mm or 0.5mm or 0.6mm or 0.7mm, and so on.

In this embodiment, too small a hole diameter of the first silencing hole 101 increases the flow resistance of the refrigerant, so as to reduce the heat exchange efficiency of the air conditioner, too large a hole diameter of the first silencing hole 101 cannot effectively reduce the pressure pulsation in the refrigerant, and based on this, the hole diameter of the first silencing hole 101 is 0.3mm to 0.8mm, so that the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be effectively considered.

Further, in an embodiment, referring to fig. 1, the outer diameter D1 of the refrigerant tube 11 is not smaller than 6mm and not larger than 10mm.

For example, the outer diameter D1 of the refrigerant pipe 11 may be 7mm, 8mm, 9mm, or the like.

The pipe diameter of the refrigerant pipe 11 can be specifically determined according to the pipe diameter of a refrigerant connecting pipeline in the accessed air conditioner.

In this embodiment, the outer diameter of the refrigerant pipe 11 is between 6mm and 10mm, so that the adaptability and convenience of the refrigerant adjusting device 1 in accessing the air conditioner pipeline can be ensured, and meanwhile, the increase of unstable flow of the refrigerant caused by overlarge pipe diameter difference between the refrigerant pipe 11 and the air conditioner pipeline is reduced, thereby further effectively reducing the refrigerant sound generated when the refrigerant adjusting device 1 is applied.

Further, in an embodiment, referring to fig. 1 and 2, the housing 13 includes a first connecting plate 131, a side plate 132, and a second connecting plate 133, where the side plate 132 is spaced from the outer wall of the refrigerant tube 11 and is aligned with the plurality of first silencing holes 101, one side of the first connecting plate 131 is connected to the tube wall of the refrigerant tube 11, the other side of the first connecting plate 131 is connected to one side of the side plate 132, the other side of the side plate 132 is connected to one side of the second connecting plate 133, and the other side of the second connecting plate 133 is connected to the tube wall of the refrigerant tube 11.

The vertical projection of the side plate 132 on the outer wall of the refrigerant pipe 11 covers all the first sound deadening holes 101.

In the present embodiment, the side plate 132 is disposed parallel to the outer wall of the refrigerant tube 11 on the side of the refrigerant tube 11. In other embodiments, the plate surface of the side plate 132 near the refrigerant tube 11 may be inclined with respect to the outer wall of the refrigerant tube 11.

In other embodiments, the first connecting plate 131 and the second connecting plate 133 may be disposed perpendicular to the outer wall of the refrigerant tube 11.

In this embodiment, according to the above arrangement, it is advantageous to improve the uniformity of mixing the gas-liquid two-phase refrigerant while reducing the flow resistance of the refrigerant in the refrigerant adjusting device 1.

Further, in an embodiment, referring to fig. 1, a length L2 of the housing 13 along the axial direction of the refrigerant tube 11 is not less than 10mm and not more than 15mm.

For example, the length L2 of the housing 13 in the circumferential direction of the refrigerant tube 11 may be 11mm or 12mm or 13mm or 14mm, or the like.

In this embodiment, the axial length of the casing 13 along the refrigerant pipe 11 is too long, so that the flow resistance of the refrigerant can be increased to reduce the heat exchange efficiency of the air conditioner, and the axial length of the casing 13 along the refrigerant pipe 11 is too short to effectively reduce the pressure pulsation in the refrigerant, so that the axial length of the casing 13 along the refrigerant pipe 11 is 10mm to 15mm, and the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be effectively considered.

Further, in an embodiment, in conjunction with fig. 1, the outer diameter D2 of the housing 13 is not less than 12mm and not more than 18mm.

For example, the outer diameter D2 of the housing 13 may be 13mm or 14mm or 15mm or 17mm, etc.

In this embodiment, too small an outer diameter of the housing 13 cannot provide a large enough space for mixing gas and liquid phases, which affects the noise reduction effect of the throttling device 2, and too large an outer diameter of the housing 13 can cause too much refrigerant to enter the silencing cavity 12 to increase resistance and affect the heat exchange effect of an air conditioner in which the refrigerant is located, based on which the outer diameter D2 of the housing 13 is between 12mm and 18mm, so that the heat exchange efficiency of the air conditioner and the noise reduction effect of the throttling device 2 can be guaranteed.

Further, in an embodiment, the refrigerant pipe 11 is a metal pipe.

For example, the refrigerant pipe 11 may be a copper pipe or an aluminum pipe.

In the present embodiment, the partition 14 is integrally formed with the refrigerant pipe 11. In other embodiments, the partition 14 may be fixed to the inner wall of the refrigerant tube 11 by welding, plugging, or the like.

In the present embodiment, the second sound deadening hole 141 is circular in cross section in the radial direction. In other embodiments, the cross section of the second sound deadening hole 141 in the radial direction may also be rectangular, triangular, or the like.

The interval between any two adjacent ones of the plurality of second sound deadening holes 141 may be the same or different.

The number of the plurality of second sound deadening holes 141 may be set according to the area and/or thickness of the partition plate 14 and/or the minimum distance from the first sound deadening hole 101, etc.

After the two-phase refrigerant is mixed in the first pipe section and the silencing cavity 12, the refrigerant flowing out of the first pipe section can be mixed with gas and liquid again when flowing through the partition plate 14, so that unstable flows such as Taylor bubbles and vortexes are effectively eliminated.

In this embodiment, the porous partition plate 14 is disposed on the first pipe section, so that the uniform stability of the refrigerant adjusted by the refrigerant adjusting device 1 is further improved, and the noise of the throttling device 2 is further reduced.

Further, in an embodiment, referring to fig. 5, the aperture D3 of the second silencing hole 141 is not smaller than 0.5mm and not larger than 1mm.

For example, the aperture D3 of the second sound deadening hole 141 may be 0.6mm or 0.7mm or 0.9mm, or the like.

In this embodiment, too small a hole diameter of the second silencing hole 141 increases the flow resistance of the refrigerant to reduce the heat exchange efficiency of the air conditioner, too large a hole diameter of the second silencing hole 141 cannot effectively reduce the pressure pulsation in the refrigerant, and based on this, the hole diameter of the second silencing hole 141 is 0.5mm and not more than 1mm, which can ensure the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 to be effectively combined.

Further, in an embodiment, referring to fig. 4 and 5, the partition 14 is provided with a plurality of groups of second silencing holes 141, and the plurality of groups of second silencing holes 141 are arranged at intervals along the radial direction of the refrigerant pipe 11, and each group of second silencing holes 141 includes a plurality of second silencing holes 141 arranged at intervals along the circumferential direction of the refrigerant pipe 11.

In the present embodiment, the intervals between the adjacent two sets of the second sound deadening holes 141 are the same. Or the interval between the adjacent two sets of the second sound deadening holes 141 may be different.

In the present embodiment, the number of the second sound deadening holes 141 per group gradually increases from the center of the partition plate 14 toward the edge of the partition plate 14.

In this embodiment, the second silencing holes 141 are provided in the above manner, so that uniformity and stability of the refrigerant in the first pipe section after passing through the second silencing holes 141 in different positions can be effectively improved, thereby being beneficial to further reducing noise in the refrigerant pipe 11.

Further, in an embodiment, referring to fig. 5, a distance L5 between any adjacent two second sound deadening holes 141 in each set of second sound deadening holes 141 is not less than 0.3mm and not more than 0.8mm.

For example, the interval L5 between the adjacent two second sound deadening holes 141 may be 0.5mm or 0.6mm or 0.7mm or the like.

In this embodiment, the too large interval between the two adjacent groups of second silencing holes 141 can increase the flow resistance of the refrigerant and reduce the heat exchange efficiency of the air conditioner, and the too small interval between the two adjacent groups of second silencing holes 141 can not effectively reduce the pressure pulsation in the refrigerant, based on this, the interval between the two adjacent groups of second silencing holes 141 is 0.3mm to 0.8mm, so that the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be guaranteed.

Further, in an embodiment, referring to fig. 5, a distance L4 between any two adjacent second silencing holes 141 of the plurality of sets of second silencing holes 141 along the radial direction of the refrigerant tube 11 is not less than 0.3mm and not more than 0.8mm.

For example, the interval L4 between adjacent two second sound deadening holes 141 may be 0.5mm or 0.6mm or 0.7mm or the like.

In this embodiment, the too large interval between any two adjacent second silencing holes 141 along the radial direction of the refrigerant pipe 11 increases the refrigerant flow resistance, so as to reduce the heat exchange efficiency of the air conditioner, and the too small interval between any two adjacent second silencing holes 141 along the radial direction of the refrigerant pipe 11 can not effectively reduce the pressure pulsation in the refrigerant, based on this, the interval between any two adjacent second silencing holes 141 along the radial direction of the refrigerant pipe 11 is 0.3mm to 0.8mm, so that the heat exchange efficiency of the air conditioner and the noise reduction of the throttling device 2 can be ensured.

Further, in one embodiment, the separator 14 is a metal structure.

The separator 14 may comprise an aluminum plate or a copper plate, or the like. In the present embodiment, the separator 14 and the refrigerant pipe 11 are made of the same metal.

In this embodiment, the partition 14 has a metal structure, and has good heat conductivity, corrosion resistance, and other properties, which is beneficial to reducing noise of the throttling device 2 and improving safety and ensuring heat exchange efficiency when the refrigerant adjusting device 1 is applied to an air conditioner.

Referring to fig. 6, the air conditioner includes the throttle device 2 and the refrigerant adjusting device 1, and an outlet of the refrigerant pipe 11 communicates with an inlet of the throttle device 2. The specific structure of the refrigerant adjusting device 1 refers to the above embodiments, and because the air conditioner adopts all the technical solutions of all the embodiments, at least has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

In other implementations, the throttling device may be provided at other locations of the air conditioner, such as on the air-supplementing enthalpy-increasing branch, in addition to being a throttling component between heat exchangers.
