The present application provides a method for controlling flow distribution of an air conditioner. The air conditioner may be a wall-mounted air conditioner, a cabinet-type air conditioner, a window-type air conditioner, or a ceiling-mounted air conditioner.

As shown in Figure 1 and Figure 2, the outdoor heat exchanger of the air conditioner is provided with a variable flow distribution device, which includes: a reversing valve 3, a first flow distribution pipeline 1, a second flow distribution pipeline 2 and at least two A heat exchange pipeline 4. The first distribution pipeline 1 is connected with the second distribution pipeline 2 through at least two heat exchange pipelines 4 . Both the first branch pipeline 1 and the second branch pipeline 2 are provided with a main pipeline and a plurality of branch pipelines, and check valves 10 can be provided in some of the branch pipelines as required.

The reversing valve 3 is a two-position four-way reversing valve, which is provided with a first communication port 31, a second communication port 32, a third communication port 33 and a fourth communication port 34. The reversing valve 3 has a first state and a second communication port. state. The first communication port 31 is connected to the refrigerant inlet, and the third communication port 33 is connected to the refrigerant outlet.

The air conditioner has a variable split state and a fixed split state. In the case of a variable split state, the refrigerant in the outdoor heat exchanger of the air conditioner adjusts the split state in real time; in the case of a fixed split state, the refrigerant split state in the air conditioner's outdoor heat exchanger is fixed.

The shunt state is divided into single-way shunt and multi-way shunt. In the case of multi-way shunt, the refrigerant in the outdoor heat exchanger of the air conditioner is multi-way shunted to work. In the case of one-way split flow, the refrigerant in the outdoor heat exchanger of the air conditioner works in one way. That is to say, in the variable flow state, the air conditioner switches between single flow flow and multi-way flow flow, and in the fixed flow flow state, the air conditioner works in fixed position single flow flow or multi-way flow flow.

During multi-way splitting, the reversing valve 3 is in the first state, the first communication port 31 communicates with the second communication port 32 , and the third communication port 33 communicates with the fourth communication port 34 . At this time, the second communication port 32 communicates with the first distribution pipeline 1 , and the fourth communication port 34 communicates with the second distribution pipeline 2 . The refrigerant at the inlet of the refrigerant enters through the first branch pipeline 1, diverts in the branch pipes of the first branch pipeline 1, and enters each heat exchange pipeline 4 to exchange heat with the indoor air, and then flows through the branch pipes of the second branch pipeline 2. The pipeline enters into its main pipeline, finally passes through the fourth communication port 34 and the third communication port 33, and is discharged from the refrigerant outlet, realizing heat exchange through multiple pipelines.

During one-way split flow, the reversing valve 3 is in the second state, 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 distribution pipeline 2 , and the fourth communication port 34 communicates with the first distribution pipeline 1 . The refrigerant at the refrigerant inlet enters through the second branch pipeline 2. Since the check valve 10 is set in part of the first branch pipeline 1, under its restriction, the refrigerant can only be discharged through heat exchange in part of the heat exchange pipeline 4. , at this time, the heat exchange pipeline can be reduced.

In this embodiment, two heat exchange pipelines 4 are taken as an example, namely the first heat exchange pipeline and the second heat exchange pipeline. Both the first branch pipeline 1 and the second branch pipeline 2 are provided with a main pipeline and two branch pipelines. A one-way valve 10 is provided in a branch pipeline in the first branch pipeline 1 . Assume that only one of the pipelines of the first branch pipeline 1 is provided with a one-way valve 10

During multi-way splitting, the reversing valve 3 is in the first state, the first communication port 31 communicates with the second communication port 32 , and the third communication port 33 communicates with the fourth communication port 34 . At this time, the second communication port 32 communicates with the first distribution pipeline 1 , and the fourth communication port 34 communicates with the second distribution pipeline 2 . The refrigerant at the refrigerant inlet enters through the first diversion pipeline 1, diverts in the branch pipeline of the first diversion pipeline 1, enters the first heat exchange pipeline and the second heat exchange pipeline respectively to exchange heat with the indoor air, and then passes through the second heat exchange pipeline. The branch pipe of the second branch pipe 2 enters the main pipe, passes through the fourth communication port 34 and the third communication port 33 , and is discharged from the refrigerant outlet, realizing simultaneous heat exchange of the two pipes.

During one-way split flow, the reversing valve 3 is in the second state, 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 distribution pipeline 2 , and the fourth communication port 34 communicates with the first distribution pipeline 1 . The refrigerant at the refrigerant inlet enters from the second branch pipeline 2. Since the branch pipeline in the first branch pipeline 1 is provided with a one-way valve 10, under its restriction, the refrigerant can only exchange heat in the first heat exchange pipeline 4 At this time, only one heat exchange pipeline 4 is used for heat exchange.

As shown in FIG. 3 , the control method for air-conditioning shunt includes the following steps:

Step S110: Obtain the ambient temperature where the air conditioner is located.

After the air conditioner is turned on, the user can control the air conditioner through an electronic device or a remote controller. During this process, if the air conditioner receives an instruction of the diversion function, the air conditioner uses a sensor to detect the ambient temperature of the current scene.

Step S120: Adjust the operating state of the air conditioner according to the operating mode of the air conditioner and the ambient temperature.

After obtaining the ambient temperature, adjust the operating state of the air conditioner according to the operating mode of the air conditioner. The air conditioner has a variable split state and a fixed split state. In the case of a variable split state, the refrigerant in the outdoor heat exchanger of the air conditioner adjusts the split state in real time. In the case of a fixed split state, the split state of the refrigerant in the outdoor heat exchanger of the air conditioner is fixed.

If the air conditioner is in the cooling mode, the air conditioner is adjusted to switch between the variable split state and the fixed split state according to the cooling temperature range of the ambient temperature.

For example, when the outdoor temperature is high and the ambient temperature is greater than or equal to 48 degrees Celsius, the temperature difference between the refrigerant temperature and the ambient temperature is small, and it is easy to affect the heat transfer at this temperature. The real-time adjustment of the valve enables the air conditioner to perform single-way or multi-way shunt. At this time, according to the actual situation, the air conditioner can perform heat exchange through some or all of the heat exchange pipelines to ensure the heat exchange effect.

When the outdoor temperature is normal, when the ambient temperature is less than or equal to 35 degrees Celsius, the temperature difference between the refrigerant temperature and the ambient temperature is normal. At this time, no matter whether it is a single flow or multiple flow, the heat exchange effect can be guaranteed, and the air conditioner is adjusted to a fixed flow state. The air conditioner is fixed to perform single-way shunt or multi-way shunt heat exchange.

If the air conditioner is in the heating mode, the air conditioner is adjusted to switch between the variable flow distribution state and the fixed flow distribution state according to the heating temperature range of the ambient temperature.

For example, when the outdoor temperature is low, when the ambient temperature is less than or equal to -7 degrees Celsius, the temperature difference between the refrigerant temperature and the ambient temperature is small, and it is easy to affect the heat transfer at this temperature, then adjust the air conditioner to a variable split state. The real-time adjustment of the through valve enables the air conditioner to perform single-way or multi-way shunt. At this time, according to the actual situation, the air conditioner can perform heat exchange through some or all of the heat exchange pipelines to ensure the heat exchange effect.

When the outdoor temperature is normal, when the ambient temperature is greater than or equal to 6 degrees Celsius, no matter whether it is single flow or multi-way flow, the heat exchange effect can be guaranteed, and the air conditioner is adjusted to the fixed flow state. There is no need to change the state, and the air conditioner is fixed to perform single-way shunt or multi-way shunt heat exchange.

The air-conditioning diversion control method provided in this application first obtains the ambient temperature where the air conditioner is located, adjusts the operating state of the air conditioner according to the operating mode of the air conditioner and the ambient temperature, and switches the air conditioner between a variable diversion state and a fixed diversion state, When cooling in a high temperature environment, select the variable split flow state for cooling, and when the air conditioner is heating in a low temperature environment, you can choose the variable split flow state for heating, and select the fixed flow state when the temperature is normal. The shunt state enables the air conditioner to select the best operating state under different ambient temperatures to improve the performance of the air conditioner.

As shown in Figure 4, if the air conditioner is in the cooling mode, the steps of adjusting the air conditioner to switch between the variable split state and the fixed split state according to the cooling temperature range of the ambient temperature include:

Step S410: Obtain the first boundary temperature.

During the process of adjusting the operating state, if the air conditioner is in the cooling mode, a first boundary temperature corresponding to the cooling mode is obtained, and the first boundary temperature is a critical temperature for switching the state.

Step S420: If the ambient temperature is greater than or equal to the first boundary temperature, adjust the air conditioner to a variable split flow state.

If the ambient temperature is greater than or equal to the first boundary temperature, for example, when the ambient temperature is ≥ 48°C, the temperature difference between the refrigerant temperature and the ambient temperature is small, and it is easy to affect the heat transfer at this temperature, then adjust the air conditioner to a variable split state, using four The real-time adjustment of the through valve enables the air conditioner to perform single-way or multi-way shunt. At this time, according to the actual situation, the air conditioner can perform heat exchange through some or all of the heat exchange pipelines. When the air conditioner is refrigerated, the multi-way split flow can be selected to further exert its ability. Therefore, when the air conditioner is refrigerated, the multi-way split flow is usually selected to improve the effect of the air conditioner.

Step S430: If the ambient temperature is lower than the first boundary temperature, adjust the air conditioner to a fixed split flow state.

If the ambient temperature is lower than the first boundary temperature, for example, when the ambient temperature is <48°C, the temperature difference between the refrigerant temperature and the ambient temperature is normal, and both single-channel split flow and multi-channel split flow can achieve heat exchange effects, then the fixed split flow state can be selected. There is no need to change the state, and the air conditioner is fixed to perform single-way shunt or multi-way shunt heat exchange.

As shown in Figure 5, if the air conditioner is in the heating mode, the steps of adjusting the air conditioner to switch between the variable split state and the fixed split state according to the heating temperature range of the ambient temperature include:

Step S510: Obtain the second boundary temperature.

During the process of adjusting the operating state, if the air conditioner is in the heating mode, then a second boundary temperature corresponding to the heating mode is obtained, and the second boundary temperature is a critical temperature for switching the state.

Step S520: If the ambient temperature is less than or equal to the second boundary temperature, adjust the air conditioner to a variable split state.

If the ambient temperature is less than or equal to the second boundary temperature, for example, when the ambient temperature is ≤ -7°C, the temperature difference between the refrigerant temperature and the ambient temperature is small, and it is easy to affect the heat exchange at this temperature, then adjust the air conditioner to a variable split state, use The real-time adjustment of the four-way valve enables the air conditioner to perform single-way or multi-way shunt. At this time, according to the actual situation, the air conditioner can perform heat exchange through some or all of the heat exchange pipelines. When the air conditioner is heating, choose a single-way split flow, which can further exert its capacity. Therefore, when the air conditioner is heating, usually choose a single-way split flow to increase the subcooling degree of the air conditioner.

Step S530: If the ambient temperature is greater than the second boundary temperature, adjust the air conditioner to a fixed split flow state.

If the ambient temperature is greater than the second boundary temperature, for example, when the ambient temperature is > -7°C, the temperature difference between the refrigerant temperature and the ambient temperature is normal, and both single-channel split flow and multi-channel split flow can achieve heat exchange effects, then the fixed split flow state can be selected. There is no need to change the state, and the air conditioner is fixed to perform single-way shunt or multi-way shunt heat exchange.

In order to ensure the working effect of the air conditioner in the variable split state, after the air conditioner has been running for a period of time, step S120: after adjusting the operating state of the air conditioner according to the operation mode of the air conditioner and the ambient temperature, further includes:

Step S130: control to increase the operating frequency of the compressor in the air conditioner.

Step S140: Obtain the exhaust temperature of the air conditioner.

After the air conditioner is in the variable split state, the air conditioner can perform single-way split or multi-way split. In the process of changing from one-way split flow to single-way split flow, the operating frequency of the compressor in the air conditioner is controlled to increase, and the exhaust temperature of the air conditioner is obtained, that is, the temperature of the refrigerant flowing out of the variable split flow device is obtained.

Step S150: According to the operation mode of the air conditioner, it is judged whether the exhaust gas temperature reaches the threshold.

According to the operating mode of the air conditioner, it is judged whether the exhaust gas temperature reaches the threshold. When the air conditioner is in the cooling state, it is judged whether the exhaust gas temperature has reached the limit value during cooling. When the air conditioner is in the heating state, it is judged whether the exhaust gas temperature reaches the limit value during heating.

Step S150: If the exhaust gas temperature reaches the threshold, the compressor is controlled to keep running at the current operating frequency, and the operating frequency of the compressor is controlled to decrease after running for a preset time.

If the exhaust temperature reaches the threshold value, that is, the exhaust temperature reaches the limit value, in order to ensure the normal operation of the air conditioner at this time, due to the hysteresis of the exhaust temperature, firstly control the compressor to maintain the current operating frequency, and control after the preset time Reduce the operating frequency of the compressor to make the air conditioner work normally.

If the discharge temperature does not reach the threshold, that is, the discharge temperature reaches the limit value, the control continues to increase the operating frequency of the compressor, and returns to the step of controlling the increase of the operating frequency of the compressor in the air conditioner after increasing the frequency. Continue to obtain the exhaust temperature of the air conditioner, judge again whether the exhaust temperature reaches the threshold, and adjust the frequency of the compressor again to ensure that the compressor is in a state of full load.

In order to ensure that the frequency of the compressor can be adjusted in real time, after reducing the operating frequency of the compressor, return to the step of controlling the increase of the operating frequency of the compressor in the air conditioner. Continue to obtain the exhaust temperature of the air conditioner, judge again whether the exhaust temperature reaches the threshold, and adjust the frequency of the compressor again to ensure that the compressor is in a state of full load, thereby ensuring the effect of the air conditioner.
