The first tapping line 1 is connected to the second tapping line 2 via at least two heat exchange lines 4. The first branch pipeline 1 and the second branch pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and a one-way valve 10 can be arranged in the middle branch pipeline according to requirements.
The change valve 3 is a two-position four-way change valve, and is provided with a first communication port 31, a second communication port 32, a third communication port 33, and a fourth communication port 34, and the change valve 3 has a first station and a second station. The first communication port 31 is connected to the refrigerant inlet, and the third communication port 33 is connected to the refrigerant outlet.
The shunting state is divided into single-path shunting and multi-path shunting, and under the condition of multi-path shunting, refrigerant in an outdoor heat exchanger or an indoor heat exchanger of the air conditioner is subjected to multi-path shunting to work. Under the condition of single-path flow division, the refrigerant in an outdoor heat exchanger or an indoor heat exchanger of the air conditioner works in a single path.
When the multi-path flow is divided, the change valve 3 is in the first position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant of the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipelines of the first shunting pipeline 1, respectively enters each heat exchange pipeline 4 to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 by the branch pipelines, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the heat exchange of a plurality of pipelines is realized.

At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valves 10 are arranged in part of pipelines in the first shunting pipeline 1, and under the limitation of the check valves, the refrigerant can only be subjected to heat exchange and discharged from part of the heat exchange pipelines 4, and at the moment, the heat exchange pipelines can be reduced.
In this embodiment, taking two heat exchange pipelines 4 as an example, the two heat exchange pipelines are respectively a first heat exchange pipeline and a second heat exchange pipeline. First reposition of redundant personnel pipeline 1 and second reposition of redundant personnel pipeline 2 all are equipped with a trunk line and two spinal branchs way. A one-way valve 10 is arranged in one branch pipeline of the first shunt pipeline 1. It is assumed that the non-return valve 10 is arranged in only one of the conduits of the first tapping line 1
When the multi-path flow is divided, the change valve 3 is in the first position, the first communication port 31 is communicated with the second communication port 32, and the third communication port 33 is communicated with the fourth communication port 34. At this time, the second communication port 32 communicates with the first branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant at the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipeline of the first shunting pipeline 1, respectively enters the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 from the branch pipeline, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
When the one-way flow is branched, the selector valve 3 is in the second position, the first communication port 31 communicates with the fourth communication port 34, and the third communication port 33 communicates with the second communication port 32. At this time, the second communication port 32 communicates with the second branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valve 10 is arranged in the branch pipeline in the first shunting pipeline 1, the refrigerant can only exchange heat in the first heat exchange pipeline 4 and be discharged under the limitation of the check valve, and at the moment, the heat exchange is carried out only through one heat exchange pipeline 4.
As shown in fig. 3, the control method for noise reduction of an air conditioner includes the following steps:
step S310: and acquiring the vibration condition of the compressor.
After the air conditioner is started and stably works, the air conditioner acquires the vibration condition of the compressor through the sensor.
In order to minimize noise of the entire air conditioner, the vibration condition of the compressor includes vibration conditions of the compressor itself and parts contacting the compressor around the compressor. That is, sensors may be provided on the compressor body and other components in contact with the compressor, and the vibration condition may be determined by data detected by the respective sensors.
Step S320: and adjusting the shunting state of the air conditioner based on the vibration condition.
And after the vibration condition is determined, adjusting the shunting state of the air conditioner according to the vibration magnitude. The shunting state comprises the following steps: single-path shunting and multi-path shunting; the refrigerant is divided in a single path, and the refrigerant in a heat exchanger of the air conditioner works in the single path; in the multi-path flow distribution, the refrigerant in the heat exchanger of the air conditioner works in multiple paths.
Specifically, after the vibration condition of the compressor is acquired, whether the vibration condition is in a preset vibration range is judged. If the vibration is out of the preset vibration range, the vibration of the compressor is larger, the noise of the air conditioner is larger in the state, and in order to avoid the section generating the noise by the vibration, the air conditioner is controlled to change the flow dividing state.
And when the vibration condition is within the preset vibration range, the vibration condition of the compressor is normal at the moment, and the shunting state does not need to be adjusted.
For example, the preset vibration range is 0 to 280 μ ∈, and when the vibration of the compressor is determined to be greater than 280 μ ∈, the vibration condition is determined to be outside the preset vibration range. And when the vibration of the compressor is determined to be less than or equal to 280 mu epsilon, judging that the vibration condition is in a preset vibration range, wherein the vibration condition of the compressor is normal and the shunting state of the air conditioner does not need to be adjusted.
According to the control method for air conditioner noise reduction, the vibration condition of the compressor is obtained, the shunting state of the air conditioner is adjusted based on the vibration condition, so that the air conditioner can adjust the shunting state according to the vibration condition, the noise frequency zone is avoided, the air conditioner noise is reduced, and the user experience is improved.
In order to avoid the noise generated by the operating frequency of the compressor, as shown in fig. 4, the step of adjusting the split state of the air conditioner based on the vibration condition further includes:
step S410: and if the vibration condition is within the preset vibration range, acquiring the working frequency of the compressor.
When the vibration condition is within the preset vibration range, the vibration condition of the compressor is normal, and in order to further avoid noise, the air conditioner acquires the working frequency of the compressor through the sensor.
Step S420: and adjusting the shunting state of the air conditioner based on the working frequency.
And after the working frequency of the compressor is determined, the shunting state of the air conditioner is adjusted according to the working frequency. The shunting state comprises the following steps: single-path shunting and multi-path shunting; the refrigerant is divided in a single path, and the refrigerant in a heat exchanger of the air conditioner works in the single path; in the multi-path flow distribution, the refrigerant in the heat exchanger of the air conditioner works in multiple paths.
Specifically, after the working frequency of the compressor is obtained, whether the working frequency is within a preset frequency range is judged. If the working frequency is out of the preset frequency range, the working frequency of the compressor is larger, the noise of the air conditioner is larger in the state, and in order to avoid a section generating the noise by the frequency, the air conditioner is controlled to change the shunting state.
And when the working frequency is within the preset frequency range, the working frequency of the compressor is normal at the moment, and the shunting state of the air conditioner is not required to be adjusted.
For example, the preset frequency range is 0 to 6000Hz, and when the working frequency of the compressor is determined to be greater than 6000Hz, the working frequency is determined to be outside the preset vibration range. And when the working frequency of the compressor is determined to be less than or equal to 6000Hz, the working frequency is judged to be within the preset vibration range, and the working frequency of the compressor is normal at the moment without adjusting the shunting state of the air conditioner.
When the working frequency and the vibration condition are normal, if noise reduction is required, as shown in fig. 5, the step of adjusting the shunting state of the air conditioner based on the working frequency includes:
step S510: and if the working frequency is within the preset frequency range, acquiring the working noise of the compressor.
When the working frequency is within the preset frequency range, the working frequency of the compressor is normal at the moment, and in order to further avoid noise, the air conditioner directly obtains the working noise of the compressor through the sensor.
The operating noise may include noise of the compressor itself and components in contact with the compressor around the compressor. That is, sensors may be provided on the compressor body and other components in contact with the compressor, and the noise may be determined by data detected by the respective sensors.
Step S520: and adjusting the shunting state of the air conditioner based on the working noise.
After the working noise of the compressor is determined, the shunting state of the air conditioner is adjusted according to the working noise. The shunting state comprises the following steps: single-path shunting and multi-path shunting; the refrigerant is divided in a single path, and the refrigerant in a heat exchanger of the air conditioner works in the single path; in the multi-path flow distribution, the refrigerant in the heat exchanger of the air conditioner works in multiple paths.
Specifically, after the working noise of the compressor is obtained, whether the working noise is within a preset noise range is judged. If the working noise is out of the preset noise range, the working noise of the compressor is larger, and the noise of the air conditioner is larger in the state, the air conditioner is controlled to change the shunting state.
And when the working noise is within the preset noise range, the noise of the compressor is normal at the moment, and the shunting state does not need to be adjusted.
For example, the preset noise range is 0 to 48 db, and when the noise of the compressor is determined to be greater than 48 db, it is determined that the noise is outside the preset vibration range. And when the noise of the compressor is determined to be less than or equal to 48 decibels, the noise is judged to be in a preset noise range, and the shunting state does not need to be adjusted.
Based on the above embodiments, in one embodiment, as shown in fig. 6, the step of adjusting the split-flow state of the air conditioner includes:
step S610: and acquiring the shunting state of the air conditioner.
In the process of adjusting the air conditioner shunting state, acquiring the current air conditioner shunting state, wherein the current air conditioner shunting state comprises the following steps: single-pass shunting and multi-pass shunting. The refrigerant in the indoor heat exchanger and/or the outdoor heat exchanger is divided in a single path to work in a single path; in the multi-path shunting, the refrigerant in the indoor heat exchanger and/or the outdoor heat exchanger works in multiple paths.
Step S620: and if the air conditioner is in single-path shunting, adjusting the air conditioner to work in multi-path shunting.
If the current indoor heat exchanger and/or outdoor heat exchanger is in single-path shunting, the shunting state of the indoor heat exchanger and/or outdoor heat exchanger is adjusted, so that the indoor heat exchanger and/or outdoor heat exchanger work in multi-path shunting, and a section with noise caused in single-path shunting can be avoided.
Three or four heat exchange pipelines can be arranged according to the requirement, so that the shunting state can also be set to be a partially shunted intermediate state, and the selection can be carried out according to the requirement in the operation process. When three or four heat exchange pipelines are arranged, if the air conditioner is in single-path shunting, the air conditioner can be adjusted to be in partial shunting for working.
Step S630: and if the air conditioner is in multi-path shunting, adjusting the air conditioner to work in single-path shunting.
If the current indoor heat exchanger and/or outdoor heat exchanger is in multi-path shunting, the shunting state of the indoor heat exchanger and/or outdoor heat exchanger is adjusted, so that the indoor heat exchanger and/or outdoor heat exchanger work in single-path shunting, and a section with noise caused by multi-path shunting can be avoided.
When three or four heat exchange pipelines are arranged, if the air conditioner is in multi-path shunting, the air conditioner can be adjusted to be in partial shunting for working.
The following describes the control system for reducing noise of an air conditioner according to an embodiment of the present invention, and the control system for reducing noise of an air conditioner described below and the control method described above may be referred to correspondingly.
