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, the indoor heat exchanger of the air conditioner is provided with a variable flow diversion device, which includes: a reversing valve 3, a first flow diversion pipeline 1, a second flow diversion pipeline 2 and at least two heat exchangers 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 indoor 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 indoor 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 indoor heat exchanger of the air conditioner works with multi-way shunt. In the case of single-way split flow, the refrigerant in the indoor heat exchanger of the air conditioner works in a single 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. 2, 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 the instruction of the diversion function, the air conditioner uses the 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 indoor 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 indoor 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 flow distribution state and the fixed flow distribution 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, Change the split state of the refrigerant in the indoor heat exchanger. When cooling in a high temperature environment, select the variable split state for cooling, and when the air conditioner is heating in a low temperature environment, you can choose the variable split state Heating is carried out, and a fixed shunt state is selected when the temperature is normal, so that the air conditioner can select the best operating state under different ambient temperatures and improve the performance of the air conditioner.

As shown in Table 1, the cooling temperature range includes: the first cooling interval, the second cooling interval and the third cooling interval whose temperatures are set in sequence from low to high. As shown in Figure 3, 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 S310: If the ambient temperature is in the first cooling zone, adjust the air conditioner to a fixed split flow state.

For example, the ambient temperature corresponds to level T1. When the ambient temperature is less than or equal to 35°C, the temperature difference between the refrigerant temperature and the ambient temperature is normal. Both single-channel split flow and multi-channel split flow can achieve heat exchange effects, and the air conditioner is adjusted to a fixed split 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.

Step S320: If the ambient temperature is in the second cooling zone, adjust the air conditioner to a fixed flow distribution state or a variable flow distribution state.

For example, the ambient temperature corresponds to level T2, and when the ambient temperature is between 35°C and 48°C, it is determined whether the variable shunt state is required according to the user's needs, so as to adjust the working state of the air conditioner.

Step S330: If the ambient temperature is in the third cooling zone, adjust the air conditioner to a variable split flow state.

For example, the ambient temperature corresponds to grade T3. When the ambient temperature is greater than or equal to 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. Real-time adjustment 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.

Table 1

As shown in Table 1, the heating temperature range includes: the first heating zone, the second heating zone and the third heating zone in which the temperature is set in sequence from high to low. As shown in Figure 4, 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 S410: If the ambient temperature is in the first heating zone, adjust the air conditioner to a fixed split flow state.

For example, the ambient temperature corresponds to level T1. When the ambient temperature is greater than or equal to 6°C, the temperature difference between the refrigerant temperature and the ambient temperature is normal. Both single-channel split flow and multi-channel split flow can achieve heat exchange effects, and the air conditioner is adjusted to a fixed split 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.

Step S420: If the ambient temperature is in the second heating zone, adjust the air conditioner to a fixed flow distribution state or a variable flow distribution state.

For example, the ambient temperature corresponds to grade T2, and when the ambient temperature is between -7°C and 6°C, it is determined whether a variable shunt state is required according to user needs, so as to adjust the working state of the air conditioner.

Step S430: If the ambient temperature is in the third heating zone, adjust the air conditioner to a variable flow distribution state.

For example, the ambient temperature corresponds to grade T3. When the ambient temperature is less than or equal to -7°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. 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. 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.

Due to the difference between the air inlet temperature and the ambient temperature, after the air conditioner has been running for a period of time, in order to ensure the working effect of the air conditioner, as shown in Figure 5, in step S120: adjust the operating state of the air conditioner according to the operating mode of the air conditioner and the ambient temperature. include:

Step S130: Obtain the air inlet temperature of the air conditioner.

After adjusting the operating state of the air conditioner, use the sensor to detect the inlet air temperature.

Step S140: According to the operating mode and operating state of the air conditioner, determine whether the inlet air temperature meets the requirement.

If the air conditioner is in the cooling mode, it is judged whether the current operating state of the air conditioner is normal and whether the inlet air temperature is within the correct cooling temperature range according to the cooling temperature range of the inlet air temperature.

If the air conditioner is in the heating mode, then according to the heating temperature range of the inlet air temperature, it is judged whether the current operation status of the air conditioner is normal, and whether the inlet air temperature is within the correct heating temperature range.

Step S150: If the inlet air temperature meets the requirement, then control to maintain the running state of the air conditioner.

Step S160: If the inlet air temperature does not meet the requirement, then adjust the operating state, and return to the step of obtaining the air inlet temperature of the air conditioner.

For example, when the air conditioner is in the cooling mode, if it detects that the inlet air temperature is less than or equal to 35°C, the air conditioner should correspond to the fixed split flow state, using single-way split or multi-way split. If the air conditioner is in the variable flow distribution state at this time, adjust the operating state to the fixed flow distribution state, and return to the step of obtaining the air inlet temperature of the air conditioner. If the air conditioner is in the fixed split flow state at this time, the running state of the air conditioner is maintained.

When the air conditioner is in cooling mode, if it detects that the inlet air temperature is greater than or equal to 48°C, the air conditioner should correspond to the variable split state and adjust the split state in real time. If the air conditioner is in the variable diversion state at this time, the running state of the air conditioner is maintained. If the air conditioner is in the fixed split flow state at this time, adjust the operating state to the variable split flow state, and return to the step of obtaining the air inlet temperature of the air conditioner.

When the air conditioner is in the heating mode, if it detects that the inlet air temperature is greater than or equal to 6°C, the air conditioner should correspond to the fixed flow state, and the fixed flow is single-way or multi-way. If the air conditioner is in the variable flow distribution state at this time, adjust the operating state to the fixed flow distribution state, and return to the step of obtaining the air inlet temperature of the air conditioner. If the air conditioner is in the fixed split flow state at this time, the running state of the air conditioner is maintained.

If the ambient temperature is less than or equal to -7°C, the air conditioner should correspond to the variable shunt state and adjust the shunt state in real time. If the air conditioner is in the variable diversion state at this time, the running state of the air conditioner is maintained. If the air conditioner is in the fixed split flow state at this time, adjust the operating state to the variable split flow state, and return to the step of obtaining the air inlet temperature of the air conditioner.
