The first diversion pipeline 1 and the second diversion pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and one-way valves 10 can be arranged in part of the branch pipelines according to the requirement.
The reversing valve 3 is a two-position four-way reversing 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 reversing valve 3 is provided with 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 air conditioner has a variable split state and a fixed split state. In the case of a variable split state, the split state is adjusted by cooling in the heat exchanger of the air conditioner according to the operation mode of the air conditioner. In the case of the fixed split state, the split state of the refrigerant in the outdoor heat exchanger of the air conditioner is fixed.
The split state is divided into single-path split and multi-path split, and refrigerant multi-path split in the outdoor heat exchanger of the air conditioner works under the condition of multi-path split. Under the condition of single-way split flow, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single way. That is, in the variable split state, the air conditioner is switched between the single split and the multi-split, and in the fixed split state, the air conditioner is fixed to operate in the single split or the multi-split.
When the multi-way flow is split, the reversing valve 3 is positioned at a first station, 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 shunt line 1, and the fourth communication port 34 communicates with the second shunt line 2.

When the single-way flow is split, the reversing valve 3 is at the second station, the first communication port 31 is communicated with the fourth communication port 34, and the third communication port 33 is communicated with the second communication port 32. At this time, the second communication port 32 communicates with the second split line 2, and the fourth communication port 34 communicates with the first split line 1. The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in part of the pipelines in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in part of the heat exchange pipeline 4 under the limitation of the one-way valve, and the heat exchange pipeline can be reduced at the moment.
In this embodiment, two heat exchange pipelines 4 are taken as an example, and are a first heat exchange pipeline and a second heat exchange pipeline respectively. The first shunt pipeline 1 and the second shunt pipeline 2 are respectively provided with a main pipeline and two branch pipelines. One branch pipe in the first diversion pipeline 1 is provided with a one-way valve 10. It is assumed that the non-return valve 10 is provided in only one of the branch lines of the first shunt line 1.
When the multi-way flow is split, the reversing valve 3 is positioned at a first station, 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 shunt line 1, and the fourth communication port 34 communicates with the second shunt line 2.

The refrigerant of the refrigerant inlet enters from the second diversion pipeline 2, and the one-way valve 10 is arranged in the branch pipeline in the first diversion pipeline 1, so that the refrigerant can only exchange heat and discharge in the first heat exchange pipeline 4 under the limitation of the one-way valve, and only exchanges heat through one heat exchange pipeline 4 at the moment.
As shown in fig. 3, the control method of the air conditioner self-cleaning comprises the following steps:
step S110: and under the condition that the self-cleaning condition is met, controlling the air conditioner to enter a self-cleaning mode.
After the air conditioner is started, the air conditioner can automatically judge whether the air conditioner meets the self-cleaning condition, for example, whether the running time of the air conditioner is larger than a set accumulated running threshold value, if the running time is larger than the set accumulated running threshold value, the air conditioner is indicated to meet the self-cleaning condition, and the air conditioner is controlled to enter a self-cleaning mode.
For example, in case that the self-cleaning condition is satisfied, the air conditioner is controlled to operate in a cooling mode to self-clean the indoor heat exchanger. And condensing the water vapor in the air conditioner into liquid water by using an indoor heat exchanger of the air conditioner, and cleaning the indoor heat exchanger by using the liquid water.
Step S120: and acquiring the ambient temperature of the air conditioner and the cold-out temperature of the heat exchanger.
In the cleaning process of the indoor heat exchanger, the air conditioner control sensor detects the ambient temperature of the current scene, wherein the ambient temperature can be the indoor temperature or the outdoor temperature, and the cold outlet temperature of the indoor heat exchanger is obtained, and the cold outlet temperature is the refrigerant temperature at the outlet of the indoor heat exchanger.
Step S130: and adjusting the running state of the air conditioner according to the ambient temperature and the cold-out temperature.
After the ambient temperature and the cool-out temperature are acquired, the air conditioner is controlled to switch between a variable split state and a fixed split state based on the acquired ambient temperature and cool-out temperature. In the case of a variable split state, the split state is adjusted by cooling in a heat exchanger of the air conditioner according to the working mode of the air conditioner; in the case of the fixed split state, the split state of the refrigerant in the heat exchanger is fixed.
Specifically, after the ambient temperature and the cold-out temperature are obtained, whether the ambient temperature and the cold-out temperature meet the working conditions corresponding to the self-cleaning mode is judged. If the working conditions corresponding to the self-cleaning mode are met, the air conditioner can work normally in the current split state, and the single-path split or multi-path split can meet the requirements, so that the air conditioner is controlled to be in a fixed split state. In order to reduce the energy consumption, the work can also be performed in a single-way split mode in the process.
If the working condition corresponding to the self-cleaning mode is not met, the air conditioner is controlled to be in a variable split state when the air conditioner cannot work normally in the current split state, and the split state of 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. For example, when the air conditioner is in a state of single-path split flow, as the self-cleaning mode of the air conditioner is a refrigerating process, the supercooling section of the air conditioner can be increased by adding the split flow, the air conditioner is controlled to be switched into multi-path split flow for heat exchange, and therefore the air conditioner achieves the optimal self-cleaning effect.
According to the control method for the self-cleaning of the air conditioner, the air conditioner is controlled to enter the self-cleaning mode under the condition that the self-cleaning condition is met, the ambient temperature of the air conditioner and the cold-out temperature of the heat exchanger are obtained in the self-cleaning process of the air conditioner, the running state of the air conditioner is controlled according to the ambient temperature and the cold-out temperature, the air conditioner is switched between the variable split state and the fixed split state, the split state of the heat exchanger is changed, and the air conditioner achieves the optimal self-cleaning effect.
As shown in fig. 4, the step of determining whether the ambient temperature and the cool-out temperature satisfy the operating conditions corresponding to the self-cleaning mode includes:
step S410: and acquiring a first boundary temperature and a second boundary temperature corresponding to the self-cleaning mode.
In the step of judging whether the working condition is met, a first boundary temperature and a second boundary temperature corresponding to the self-cleaning mode are acquired. Because the air conditioner self-cleaning mode is a refrigerating process, the first boundary temperature is a limit value of the ambient temperature during refrigeration, and the second boundary temperature is a limit value of the outlet temperature of the evaporator during refrigeration.
Step S420: and judging whether the ambient temperature exceeds the first boundary temperature or not, and judging whether the cold-out temperature exceeds the second boundary temperature or not.
After the first boundary temperature and the second boundary temperature are obtained, whether the ambient temperature exceeds the first boundary temperature or not is judged, and whether the cold-out temperature exceeds the second boundary temperature or not is judged. If the ambient temperature does not exceed the first boundary temperature and the cold-out temperature does not exceed the second boundary temperature, the air conditioner is indicated to work normally in the current split state, and the single-path split or multi-path split can meet the requirements, and the air conditioner is controlled to be in a fixed split state.
If the ambient temperature exceeds the first boundary temperature or the cold-out temperature exceeds the second boundary temperature or the ambient temperature exceeds the first boundary temperature and the cold-out temperature exceeds the second boundary temperature, the air conditioner is controlled to be in a variable split state if the air conditioner is not normally operated in the current split state.
For example, assume that the first boundary temperature is 48 degrees celsius and the second boundary temperature is 8 degrees celsius. And if the ambient temperature is higher than 48 ℃ or the cold-out temperature is higher than 8 ℃, controlling the air conditioner to be in a variable split state. And when the ambient temperature is less than 48 ℃ and the cold-out temperature is less than 8 ℃, controlling the air conditioner to be in a fixed split state.
If the air conditioner starts the self-cleaning mode and enters the fixed diversion state, the air conditioner operates in the current diversion state, and after the air conditioner starts the self-cleaning mode and enters the variable diversion state, as shown in fig. 5, the air conditioner further comprises:
step S510: and acquiring the current split state of the air conditioner.
And acquiring the current split state of the air conditioner. The shunt state mainly comprises: single-pass splitting and multi-pass splitting. Three or four heat exchange pipelines can be arranged according to the needs, so that the split state can be also provided with the intermediate state of partial split so as to ensure that the selection is carried out according to the needs in the operation process.
Step S520: if the air conditioner is in single-path split, the air conditioner is adjusted to be in multi-path split for working.
The self-cleaning mode is a refrigeration process and is used for cleaning the indoor heat exchanger, so that if the air conditioner is judged to be in single-path split, the current split state cannot ensure normal operation, the air conditioner is adjusted to be in multi-path split for operation, and a plurality of heat exchange pipelines are utilized for heat exchange, so that heat exchange of a plurality of pipelines is realized.
If the air conditioner is also provided with a partial split intermediate device, the air conditioner can be adjusted from a single-path split state to a partial split state, and heat exchange is performed by utilizing a partial heat exchange pipeline.
Step S530: if the air conditioner is already in the multi-way split, the multi-way split is kept to work.
If the air conditioner is already in the multi-way flow, the self-cleaning mode can enhance the refrigerating effect, and the self-cleaning strength reaches the maximum value at the moment, so that the multi-way flow is kept to work.
The following describes the self-cleaning control system of the air conditioner provided by the embodiment of the invention, and the self-cleaning control system of the air conditioner and the control method described above can be referred to correspondingly.
As shown in fig. 6, the control system of the air conditioner self-cleaning includes: an execution module 610, an acquisition module 620, and an adjustment module 630.
