The invention provides a control method for dehumidification of an air conditioner, wherein the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like.
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 dividing device, and the indoor heat exchanger and the outdoor heat exchanger can be provided with the variable flow dividing device at the same time, and the variable flow dividing device comprises: the system comprises a reversing valve 3, a first shunt pipeline 1, a second shunt pipeline 2 and at least two heat exchange pipelines 4. The first tapping line 1 is connected to the second tapping line 2 via at least two heat exchange lines 4. The first branch pipeline 1 and the second branch pipeline 2 are respectively provided with a main pipeline and a plurality of branch pipelines, and a one-way valve 10 can be arranged in the middle branch pipeline according to requirements.
The change valve 3 is a two-position four-way change valve, and is provided with a first communicating port 31, a second communicating port 32, a third communicating port 33 and a fourth communicating port 34, and the change valve 3 has 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. Under the condition of variable shunt state, the refrigerant in the heat exchanger of the air conditioner adjusts the shunt state. Under the condition of fixed flow dividing state, the flow dividing state of the refrigerant in the heat exchanger of the air conditioner is fixed.
The shunting state is divided into single-path shunting and multi-path shunting, and under the condition of multi-path shunting, refrigerant in the outdoor heat exchanger of the air conditioner is subjected to multi-path shunting to work. Under the condition of single-path flow division, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single path. That is, the air conditioner switches between the one-way split and the multi-way split in the variable split state, and the air conditioner is fixed to operate in the one-way split or the multi-way split in the fixed split state.
When the multi-path flow is divided, the change valve 3 is in the first position, 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 branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant of the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipelines of the first shunting pipeline 1, respectively enters each heat exchange pipeline 4 to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 by the branch pipelines, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the heat exchange of a plurality of pipelines is realized.
When the single-path flow is branched, the selector 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 branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valves 10 are arranged in part of pipelines in the first shunting pipeline 1, and under the limitation of the check valves, the refrigerant can only be subjected to heat exchange and discharged from part of the heat exchange pipelines 4, and at the moment, the heat exchange pipelines can be reduced.
In this embodiment, taking two heat exchange pipelines 4 as an example, the two heat exchange pipelines are respectively a first heat exchange pipeline and a second heat exchange pipeline. First reposition of redundant personnel pipeline 1 and second reposition of redundant personnel pipeline 2 all are equipped with a trunk line and two spinal branchs way. A one-way valve 10 is arranged in one branch pipeline of the first shunt pipeline 1. It is assumed that the non-return valve 10 is arranged in only one of the conduits of the first tapping line 1
When the multi-path flow is divided, the change valve 3 is in the first position, 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 branch line 1, and the fourth communication port 34 communicates with the second branch line 2. The refrigerant at the refrigerant inlet enters from the first shunting pipeline 1, is shunted by the branch pipeline of the first shunting pipeline 1, respectively enters the first heat exchange pipeline and the second heat exchange pipeline to exchange heat with the indoor air, enters the main pipeline of the second shunting pipeline 2 from the branch pipeline, finally passes through the fourth communicating port 34 and the third communicating port 33, and is discharged from the refrigerant outlet, so that the simultaneous heat exchange of the two pipelines is realized.
When the one-way flow is branched, the selector 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 branch line 2, and the fourth communication port 34 communicates with the first branch line 1. The refrigerant at the refrigerant inlet enters from the second shunting pipeline 2, and because the check valve 10 is arranged in the branch pipeline in the first shunting pipeline 1, the refrigerant can only exchange heat and be discharged from the first heat exchange pipeline 4 under the limitation of the check valve, and at the moment, the heat exchange is carried out only through one heat exchange pipeline 4.
As shown in fig. 3, the control method of air conditioning dehumidification includes the following steps:
step S310: and acquiring the dew point temperature and the coil temperature of the scene where the air conditioner is located.
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 located; and determining the dew point temperature of the scene by table look-up or empirical formula calculation based on the ambient temperature and the ambient humidity, and then detecting the coil temperature of the indoor unit by using a sensor of the air conditioner.
Step S320: and controlling the running state of the air conditioner based on the coil temperature and the dew point temperature.
After the coil temperature and the dew point temperature are obtained, the coil temperature and the dew point temperature are compared. The difference between the coil temperature and the dew point temperature is determined. If the difference value between the temperature of the coil pipe and the dew point temperature is in a first preset interval, adjusting the air conditioner to be in a fixed shunting state; under the condition of fixed flow dividing state, the flow dividing state of the refrigerant in the heat exchanger is fixed.
And if the difference value between the temperature of the coil pipe and the dew point temperature is in a second preset interval, adjusting the air conditioner to be in a variable shunting state. Wherein the temperature of the second preset interval is lower than the temperature of the first preset interval. Under the condition of variable shunt state, the refrigerant in the heat exchanger of the air conditioner adjusts the shunt state. Under the condition of fixed flow dividing state, the flow dividing 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 ℃, assuming that the first preset interval is-3 to 0 ℃ and the second preset interval is below-3 ℃, due to the small difference between the dew point temperature and the coil temperature, other parts of the air conditioner are not easy to generate condensation in the process of contacting and exchanging heat with indoor air, the air conditioner can normally dehumidify, and the air conditioner is adjusted to be in a fixed shunting state without adjusting the shunting state of the air conditioner.
When the dew point temperature is 16 ℃, if the acquired coil temperature is 10 ℃, because the difference value between the dew point temperature and the coil temperature is large, the air conditioner is in the process of contacting with indoor air for heat exchange, condensation is very easy to occur at other parts of the air conditioner, the air conditioner is adjusted to be in a variable shunting state, the shunting 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 cannot be directly influenced.
According to the control method for dehumidifying the air conditioner, the dew point temperature and the coil pipe temperature of the scene where the air conditioner is located are obtained, the running state of the air conditioner is controlled according to the comparison of the coil pipe temperature and the dew point temperature, the air conditioner is switched between the variable shunting state and the fixed shunting state, the shunting state of the heat exchanger is changed, condensation of the air conditioner during dehumidification 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 the variable split state includes:
step 410: and acquiring the current shunting state of the air conditioner.
And when the difference between the dew point temperature and the coil temperature is large, acquiring the shunting state of the indoor heat exchanger and/or the outdoor heat exchanger of the air conditioner. The shunting state comprises the following steps: single-pass shunting and multi-pass shunting.
Step 420: if the air conditioner is in single-path shunting, the air conditioner is adjusted to multi-path shunting to work.
And adjusting the shunting state of the heat exchanger to switch the heat exchanger between single-path shunting or multi-path shunting. Three or four heat exchange pipelines can be arranged according to the requirement, so that the shunting state can also be set to be a partially shunted intermediate state, and the selection can be carried out according to the requirement in the operation process.
If the indoor heat exchanger and/or the outdoor heat exchanger are/is in single-path shunting, the indoor heat exchanger and/or the outdoor heat exchanger are/is adjusted to work for multi-path shunting, the pressure of a refrigerant is reduced, and a supercooling section is reduced. If the air conditioner is also provided with a partial shunting intermediate device, the state of single-path shunting can be adjusted to be a partial shunting state, and partial heat exchange pipelines are utilized for heat exchange.
Step 430: and if the air conditioner is in multi-path shunting, the air conditioner continues to work in multi-path shunting.
And if the indoor heat exchanger and/or the outdoor heat exchanger are in multi-path shunting, the indoor heat exchanger and/or the outdoor heat exchanger continuously work in multi-path shunting. If the air conditioner is also provided with a partial shunting intermediate state, the shunting of the indoor heat exchanger and/or the outdoor heat exchanger can be increased in the intermediate state, the pressure of a refrigerant is reduced, the supercooling section is reduced, and after the air conditioner is adjusted to be in the variable shunting state, the shunting condition of the air conditioner is corrected in time.
After the single-way splitting or multi-way splitting is adjusted, as shown in fig. 5, the method further includes:
step 440: and acquiring the temperature of the coil of the air conditioner again.
After the shunting state is adjusted, the air conditioner obtains the temperature of the coil pipe again through the sensor.
Step 450: and if the temperature of the coil pipe obtained again is in the second preset interval, continuously adjusting the shunting state of the air conditioner, and returning to the step of obtaining the temperature of the coil pipe of the air conditioner again.
And if the temperature of the coil pipe obtained again is in the second preset interval, continuously adjusting the shunting state of the air conditioner, and returning to the step of obtaining the temperature of the coil pipe of the air conditioner again. And if the acquired temperature of the coil pipe is 10 ℃ again, the difference between the dew point temperature and the coil pipe temperature is large, continuously adjusting the shunting state of the air conditioner, returning to the step of acquiring the temperature of the coil pipe of the air conditioner again, and continuously adjusting the shunting state. For example, when the air conditioner is provided with three shunts, the three shunts can be firstly shunted by one way, if the difference between the dew point temperature and the coil temperature is found to be large, the two shunts are adjusted, and if the difference between the dew point temperature and the coil temperature is still large, the three shunts are adjusted.
Step 460: and if the temperature of the coil pipe obtained again is in the first preset interval, stopping adjusting the shunting state of the air conditioner.
And if the temperature of the coil pipe obtained again is in the first preset interval, stopping adjusting the shunting state of the air conditioner. For example, if the first preset interval is-3 to 0 ℃, the second preset interval is below-3 ℃, and the dew point temperature is 16 ℃, if the obtained coil temperature is 15 ℃, it indicates that the difference between the adjusted dew point temperature and the coil temperature is small, during the heat exchange process of the air conditioner in contact with the indoor air, condensation is not easy to occur at other parts of the air conditioner, the air conditioner can perform dehumidification normally, and the air conditioner is adjusted to be in a fixed shunting state without adjusting the shunting state of the air conditioner.
