As shown in fig. 1 and 2, the indoor heat exchanger or the outdoor heat exchanger of the air conditioner is provided with a variable flow diversion device, and the indoor heat exchanger and the outdoor heat exchanger can be simultaneously provided with the variable flow diversion device, and the variable flow diversion device comprises: the reversing valve 3, the first diversion pipeline 1, the second diversion pipeline 2 and at least two heat exchange pipelines 4. The first shunt line 1 is connected to the second shunt line 2 via at least two heat exchange lines 4. 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 in the cooling in the heat exchanger of the air conditioner. In the case of the fixed split state, the split state of the refrigerant in the 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, the air conditioner is switched between the single-path split and the multi-path split in the variable split state, and is fixed to operate as the single-path split or the multi-path split in the fixed split state.
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 first diversion pipeline 1, is diverted in branch pipelines of the first diversion pipeline 1, respectively enters into each heat exchange pipeline 4 to exchange heat with indoor air, enters into a main pipeline of the refrigerant through branch pipelines of the second diversion pipeline 2, finally passes through the fourth communication port 34 and the third communication port 33, is discharged from a refrigerant outlet, and realizes the heat exchange of a plurality of pipelines.
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 one-way 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 first diversion pipeline 1, is diverted in the branch pipeline of the first diversion pipeline 1, respectively enters into the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with indoor air, enters into the main pipeline of the refrigerant through the branch pipeline of the second diversion pipeline 2, finally passes through the fourth communication port 34 and the third communication port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
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 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 dehumidification of the air conditioner includes the steps of:
step S310: and acquiring the dew point temperature and the coil temperature of the scene where the air conditioner is positioned.
After the air conditioner is started, if a user selects a dehumidification mode of the air conditioner, acquiring the ambient temperature and the ambient humidity of a scene where the air conditioner is positioned; based on the ambient temperature and the ambient humidity, the dew point temperature of the scene is determined through table lookup or empirical formula calculation, and then the coil temperature of the indoor unit is detected by using a sensor of the air conditioner.
Step S320: the operating state of the air conditioner is controlled based on the coil temperature and the dew point temperature.
After the coil temperature and dew point temperature are obtained, the coil temperature and dew point temperature are compared. The difference between the coil temperature and the dew point temperature is determined. If the difference value between the coil temperature and the dew point temperature is in a first preset interval, the air conditioner is adjusted to be in a fixed split state; in the case of the fixed split state, the split state of the refrigerant in the heat exchanger is fixed.
And if the difference between the coil temperature and the dew point temperature is in a second preset interval, adjusting the air conditioner to be in a variable split state. Wherein the temperature of the second preset interval is lower than that of the first preset interval. In the case of a variable split state, the split state is adjusted in the cooling in the heat exchanger 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, when the dew point temperature is 16 ℃, if the obtained coil temperature is 15 ℃, the first preset interval is assumed to be-3 to 0 ℃, and the second preset interval is assumed to be below-3 ℃, because the difference between the dew point temperature and the coil temperature is smaller, condensation is not easy to occur at other parts of the air conditioner in the process of contacting and exchanging heat with indoor air, the air conditioner can dehumidify normally, and the air conditioner is adjusted to be in a fixed split state without adjusting the split state of the air conditioner.
When the dew point temperature is 16 ℃, if the obtained coil temperature is 10 ℃, the difference between the dew point temperature and the coil temperature is large, and the air conditioner is extremely easy to generate condensation in the process of contacting and exchanging heat with indoor air, the air conditioner is adjusted to be in a variable split state, the split state of the air conditioner is adjusted, the heat exchange of the air conditioner is reduced, the coil temperature is increased, and the corresponding dehumidification effect is not directly influenced.
According to the control method for dehumidifying the air conditioner, the dew point temperature and the coil temperature of the scene where the air conditioner is located are firstly obtained, the running state of the air conditioner is controlled according to the comparison between the coil temperature and the dew point 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, condensation of the air conditioner during dehumidifying is avoided, and user experience is improved.
Based on the above embodiment, as shown in fig. 4, the step of adjusting the air conditioner to a variable split state includes:
step 410: and acquiring the current split state of the air conditioner.
And when the difference between the dew point temperature and the coil temperature is large, acquiring the split state of the indoor heat exchanger and/or the outdoor heat exchanger of the air conditioner. The shunt state includes: single-pass splitting and multi-pass splitting.
Step 420: if the air conditioner is in single-path split, the air conditioner is adjusted to be in multi-path split for working.
And adjusting the split state of the heat exchanger to enable the heat exchanger to be switched between single-path split or multi-path split. 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.
If the indoor heat exchanger and/or the outdoor heat exchanger are/is in single-way split flow, the indoor heat exchanger and/or the outdoor heat exchanger are adjusted to work in multi-way split flow, so that the pressure of the refrigerant is reduced, and the supercooling section is reduced. 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 430: if the air conditioner is in the multi-way split, the air conditioner continues to work in the multi-way split.
If the indoor heat exchanger and/or the outdoor heat exchanger are in the multi-split flow, the indoor heat exchanger and/or the outdoor heat exchanger continue to operate in the multi-split flow. If the air conditioner is also provided with an intermediate state of partial split flow, the split flow of the indoor heat exchanger and/or the outdoor heat exchanger can be increased in the intermediate state, the refrigerant pressure is reduced, the supercooling section is reduced, and the split flow condition of the air conditioner is corrected in time after the air conditioner is adjusted to be in a variable split flow state.
After the single-path split or multi-path split is adjusted, as shown in fig. 5, the method further includes:
step 440: the coil temperature of the air conditioner is again acquired.
After the split state is adjusted, the air conditioner again acquires the coil temperature through the sensor.
Step 450: if the coil temperature acquired again is in the second preset interval, continuing to adjust the split state of the air conditioner, and returning to the step of acquiring the coil temperature of the air conditioner again.
If the coil temperature acquired again is in the second preset interval, continuing to adjust the split state of the air conditioner, and returning to the step of acquiring the coil temperature of the air conditioner again. Assuming that the first preset interval is-3 to 0 ℃, the second preset interval is below-3 ℃, the dew point temperature is 16 ℃, if the acquired coil temperature is 10 ℃, the split state of the air conditioner is continuously adjusted because the difference between the dew point temperature and the coil temperature is larger, and the step of acquiring the coil temperature of the air conditioner again is returned to continuously adjust the split state. For example, when the air conditioner is provided with three branches, the air conditioner can be firstly split in a single way, if the difference between the dew point temperature and the temperature of the coil is found to be larger, the air conditioner is adjusted to be split in two ways, and if the difference between the dew point temperature and the temperature of the coil is still larger, the air conditioner is adjusted to be split in three ways.
Step 460: and stopping adjusting the split state of the air conditioner if the re-acquired coil temperature is in the first preset interval.
And stopping adjusting the split state of the air conditioner if the re-acquired coil temperature is in the first preset interval. For example, if the first preset interval is-3 to 0 ℃, the second preset interval is-3 ℃ or lower, and the dew point temperature is 16 ℃, if the obtained coil temperature is 15 ℃, the difference between the adjusted dew point temperature and the coil temperature is smaller, and the air conditioner is not easy to generate condensation in the process of contacting and exchanging heat with indoor air, so that the air conditioner can dehumidify normally, and the air conditioner is adjusted to be in a fixed split state without adjusting the split state of the air conditioner.
