The present application provides a self-cleaning control method for an air conditioner, which 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 indoor heat exchanger or the outdoor heat exchanger of the air conditioner is provided with a variable flow splitting device, and the variable flow splitting device can also be set in the indoor heat exchanger and the outdoor heat exchanger at the same time. The variable flow distribution device includes: a reversing valve 3 , a first flow distribution pipeline 1 , a second flow distribution pipeline 2 and at least two heat exchange pipelines 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 station and a second communication port. Two workstations. 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 the variable split state, the refrigerant in the heat exchanger of the air conditioner adjusts the split state according to the working mode of the air conditioner. 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.

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 position, 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.

When the flow is divided into one way, the reversing 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 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 position, 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 diversion, the reversing 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 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 self-cleaning of the air conditioner includes the following steps:

Step S110: When the self-cleaning condition is met, control the air conditioner to enter the self-cleaning mode.

After the air conditioner is turned on, the air conditioner can automatically judge whether it meets the self-cleaning conditions. For example, it can judge whether the running time of the air conditioner is greater than the set cumulative running threshold. If the running time is greater than the set cumulative running threshold, it means that the air conditioner meets the self-cleaning conditions. The air conditioner enters self-cleaning mode.

For example, when the self-cleaning conditions are met, the air conditioner is controlled to operate in cooling mode to perform self-cleaning on the indoor heat exchanger. Use the indoor heat exchanger of the air conditioner to condense the water vapor in the air conditioner into liquid water, and use the liquid water to clean the indoor heat exchanger.

Step S120: Obtain the ambient temperature of the air conditioner and the cooling outlet temperature of the heat exchanger.

During the cleaning process of the indoor heat exchanger, the air conditioner control sensor detects the ambient temperature of the current scene. The ambient temperature can be the indoor temperature or the outdoor temperature, and obtains the cooling temperature of the indoor heat exchanger. The cooling temperature is the temperature of the indoor heat exchanger. The temperature of the refrigerant at the outlet.

Step S130: Adjust the operating state of the air conditioner according to the ambient temperature and the cooling outlet temperature.

After the ambient temperature and the cooling output temperature are obtained, the air conditioner is controlled to switch between the variable flow distribution state and the fixed flow distribution state based on the obtained ambient temperature and the cooling output temperature. In the case of the variable split state, the refrigerant in the heat exchanger of the air conditioner adjusts the split state according to the working mode of the air conditioner; in the case of the fixed split state, the refrigerant split state in the heat exchanger is fixed.

Specifically, after acquiring the ambient temperature and the cooling outlet temperature, it is first judged whether the ambient temperature and the cooling outlet temperature meet the working conditions corresponding to the self-cleaning mode. If the working conditions corresponding to the self-cleaning mode are met, it means that the air conditioner can work normally in the current diversion state, and the single-channel diversion or multi-channel diversion can meet the requirements, then the air conditioner is controlled to be in the fixed diversion state. In order to reduce energy consumption, in this process, it is also possible to work in the form of single-way shunt.

If the working conditions corresponding to the self-cleaning mode are not met, it means that the air conditioner cannot work normally in the current diversion state, then the air conditioner is controlled to be in a variable diversion state, and the refrigerant in the heat exchanger of the air conditioner is adjusted through the reversing valve according to the working mode of the air conditioner shunt status. For example, when the air conditioner is in the state of single-way split flow, since the self-cleaning mode of the air conditioner is a cooling process, increasing the split flow can increase the subcooling section of the air conditioner, and then control the air conditioner to switch to multi-way split flow for heat exchange, thereby making the air conditioner reach Best self-cleaning effect.

The self-cleaning control method of the air conditioner provided in this application firstly controls the air conditioner to enter the self-cleaning mode when the self-cleaning conditions are met, and obtains the ambient temperature of the air conditioner and the cooling temperature of the heat exchanger during the self-cleaning process of the air conditioner. Based on this, the operating state of the air conditioner is controlled, so that the air conditioner can be switched between the variable split state and the fixed split state, and the split state of the heat exchanger can be changed, so that the air conditioner can achieve the best self-cleaning effect.

As shown in Figure 4, the steps for judging whether the ambient temperature and the cooling outlet temperature meet the working conditions corresponding to the self-cleaning mode include:

Step S410: Obtain the first boundary temperature and the second boundary temperature corresponding to the self-cleaning mode.

In the step of judging whether the working conditions are satisfied, the first boundary temperature and the second boundary temperature corresponding to the self-cleaning mode are obtained first. Since the self-cleaning mode of the air conditioner is a cooling process, the first boundary temperature is the limit value of the ambient temperature during cooling, and the second boundary temperature is the limit value of the outlet temperature of the evaporator during cooling.

Step S420: Determine whether the ambient temperature exceeds the first boundary temperature, and determine whether the cooling outlet temperature exceeds the second boundary temperature.

After acquiring the first boundary temperature and the second boundary temperature, it is judged whether the ambient temperature exceeds the first boundary temperature, and whether the cooling outlet temperature exceeds the second boundary temperature. If the ambient temperature does not exceed the first boundary temperature, and the cooling outlet temperature does not exceed the second boundary temperature, it means that the air conditioner can work normally in the current split state, and single-way split flow or multi-way split flow can meet the requirements, then control the air conditioner as a fixed split flow state.

If the ambient temperature exceeds the first boundary temperature or the cooling outlet temperature exceeds the second boundary temperature, or the ambient temperature exceeds the first boundary temperature and the cooling outlet temperature exceeds the second boundary temperature, it means that the air conditioner cannot work normally in the current shunt state, and then control the air conditioner is a variable shunt state.

For example, assume that the first boundary temperature is 48 degrees Celsius and the second boundary temperature is 8 degrees Celsius. If the ambient temperature is greater than 48 degrees Celsius or the cooling outlet temperature is greater than 8 degrees Celsius, the air conditioner is controlled to be in a variable split state. And when the ambient temperature is less than 48 degrees Celsius and the cooling outlet temperature is less than 8 degrees Celsius, the air conditioner is controlled to be in a fixed split flow state.

When the air conditioner starts the self-cleaning mode and enters the fixed split flow state, it will run in the current split flow state, and after the air conditioner starts the self-cleaning mode and enters the variable split flow state, as shown in Figure 5, in order to enhance the self-cleaning mode, it also includes:

Step S510: Obtain the current distribution status of the air conditioner.

Obtain the current distribution status of the air conditioner. The shunt state mainly includes: single-way shunt and multi-way shunt. Three-way or four-way heat exchange pipelines can also be set according to needs, so that the split flow state can also be set in the intermediate state of partial flow, so as to ensure selection according to needs during operation.

Step S520: If the air conditioner is in single flow distribution mode, adjust to multi-way flow distribution to work.

The self-cleaning mode is a cooling process, which is used to clean the indoor heat exchanger. Therefore, if it is judged that the air conditioner is in a single-way split flow, because the current split flow state cannot guarantee normal operation, it will be adjusted to multi-way split flow. The heat exchange is carried out by the heat pipeline, and the heat exchange by multiple pipelines is realized.

If the air conditioner is also equipped with an intermediate device for partial flow, it can also be adjusted from the state of single flow flow to the state of partial flow, and use part of the heat exchange pipeline for heat exchange.

Step S530: If the air conditioner is already in multi-way flow, keep the multi-way flow to work.

If the air conditioner is already in the multi-way split flow, since the multi-way split flow can enhance the cooling effect in the self-cleaning mode, the strength of the self-cleaning has reached the maximum value at this time, then keep the multi-way split flow to work.

The following describes the control system for self-cleaning of the air conditioner provided by the embodiment of the present application. The control system for self-cleaning of the air conditioner described below and the control method described above can be referred to in correspondence.
