The invention provides a control method for dehumidification of an air conditioner. The air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner, etc.

As shown in Figures 1 and 2, a variable shunt device is provided in the indoor heat exchanger or outdoor heat exchanger of the air conditioner. A variable shunt device can also be provided in both the indoor heat exchanger and the outdoor heat exchanger at the same time. The variable flow splitting device includes: a reversing valve 3, a first splitting pipeline 1, a second splitting pipeline 2 and at least two heat exchange pipelines 4. The first branch pipe 1 is connected to the second branch pipe 2 through at least two heat exchange pipes 4 . Both the first branch pipe 1 and the second branch pipe 2 are provided with a main pipe and a plurality of branch pipes, and one-way valves 10 can be provided in some of the branch pipes as needed.

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. The reversing valve 3 has a first station and a third 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 a variable split state, the refrigerant in the heat exchanger of the air conditioner adjusts the split state. In the case of a fixed split state, the split state of the refrigerant in the heat exchanger of the air conditioner is fixed.

The shunt state is divided into single-channel shunt and multi-channel shunt. In the case of multi-channel shunt, the refrigerant in the outdoor heat exchanger of the air conditioner works in multiple channels. In the case of single-path splitting, the refrigerant in the outdoor heat exchanger of the air conditioner works in a single path. That is to say, in the variable splitting state, the air conditioner switches between single-channel splitting and multi-channel splitting, while in the fixed splitting state, the air conditioner is fixed to work in single-channel splitting or multi-channel splitting.

When the multi-channel flow is divided, the reversing valve 3 is in the first position, the first communication port 31 is connected to the second communication port 32, and the third communication port 33 is connected to the fourth communication port 34. At this time, the second communication port 32 is connected to the first branch pipe 1 , and the fourth communication port 34 is connected to the second branch pipe 2 . The refrigerant at the refrigerant inlet enters through the first branch pipe 1, branches in the branch pipes of the first branch pipe 1, enters each heat exchange pipe 4 to exchange heat with the indoor air, and then flows through the branches of the second branch pipe 2. The pipe enters its main pipe, and finally passes through the fourth communication port 34 and the third communication port 33, and is discharged from the refrigerant outlet, thereby realizing heat exchange among multiple pipelines.

During single-way diversion, the reversing valve 3 is in the second position, the first communication port 31 is connected to the fourth communication port 34, and the third communication port 33 is connected to the second communication port 32. At this time, the second communication port 32 is connected to the second branch pipe 2 , and the fourth communication port 34 is connected to the first branch pipe 1 . The refrigerant at the refrigerant inlet enters through the second branch pipe 2. Since some of the pipes in the first branch pipe 1 are provided with one-way valves 10, and under its restrictions, the refrigerant can only be discharged through heat exchange in some heat exchange pipes 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 pipe 1 and the second branch pipe 2 are provided with a main pipe and two branch pipes. A one-way valve 10 is provided in one branch pipe of the first branch pipe 1 . Assume that the one-way valve 10 is provided in only one of the first branch pipes 1

When the multi-channel flow is divided, the reversing valve 3 is in the first position, the first communication port 31 is connected to the second communication port 32, and the third communication port 33 is connected to the fourth communication port 34. At this time, the second communication port 32 is connected to the first branch pipe 1 , and the fourth communication port 34 is connected to the second branch pipe 2 . The refrigerant from the refrigerant inlet enters through the first branch pipe 1, branches in the branch pipes of the first branch pipe 1, enters the first heat exchange pipe and the second heat exchange pipe respectively to exchange heat with the indoor air, and then flows through the third heat exchange pipe. The branch pipe of the second branch pipe 2 enters its main pipe, and finally 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 pipelines.

During single-way diversion, the reversing valve 3 is in the second position, the first communication port 31 is connected to the fourth communication port 34, and the third communication port 33 is connected to the second communication port 32. At this time, the second communication port 32 is connected to the second branch pipe 2 , and the fourth communication port 34 is connected to the first branch pipe 1 . The refrigerant at the refrigerant inlet enters through the second branch pipe 2. Since the one-way valve 10 is provided in the branch pipe in the first branch pipe 1, under its restriction, the refrigerant can only exchange heat in the first heat exchange pipe 4. Discharge, at this time only one heat exchange pipe 4 is used for heat exchange.

As shown in Figure 3, the control method of air conditioning dehumidification includes the following steps:

Step S310: Obtain the dew point temperature and coil temperature of the scene where the air conditioner is located.

After the air conditioner is turned on, if the user selects the dehumidification mode of the air conditioner, the air conditioner obtains the ambient temperature and ambient humidity of the scene where it is located; based on the ambient temperature and ambient humidity, the dew point temperature of the scene is determined through a lookup table or empirical formula calculation. Then use the air conditioner's sensor to detect the coil temperature of the indoor unit.

Step S320: Control the operating status of the air conditioner based on the coil temperature and dew point temperature.

After taking the coil temperature and dew point temperature, compare the coil temperature and dew point temperature. Determine the difference between the coil temperature and the dew point temperature. If the difference between the coil temperature and the dew point temperature is within the first preset interval, the air conditioner is adjusted to a fixed split state; in the fixed split state, the split state of the refrigerant in the heat exchanger is fixed.

If the difference between the coil temperature and the dew point temperature is within the second preset interval, the air conditioner is adjusted to a variable split state. Wherein, the temperature of the second preset interval is lower than the temperature of the first preset interval. In the case of a variable split state, the refrigerant in the heat exchanger of the air conditioner adjusts the split state. In the case of a fixed split state, the split state of the refrigerant in the heat exchanger is fixed.

Specifically, when the dew point temperature is 16°C and the obtained coil temperature is 15°C, it is assumed that the first preset interval is -3 to 0°C and the second preset interval is below -3°C. Since the dew point temperature is different from the coil temperature, The difference in tube temperature is small. During the process of heat exchange between the air conditioner and the indoor air, condensation is less likely to occur in other parts of the air conditioner. The air conditioner can dehumidify normally without adjusting the shunt state of the air conditioner. Then adjust the air conditioner to the fixed shunt state.

When the dew point temperature is 16°C and the obtained coil temperature is 10°C, due to the large difference between the dew point temperature and the coil temperature, other parts of the air conditioner are easily susceptible to heat exchange during contact with the indoor air. If there is condensation, adjust the air conditioner to a variable split state. Adjust the split state of the air conditioner to reduce the heat exchange of the air conditioner and increase the coil temperature, but it will not directly affect the corresponding dehumidification effect.

The method for controlling dehumidification of an air conditioner provided by the present invention first obtains the dew point temperature and coil temperature of the scene where the air conditioner is located, and compares the coil temperature and the dew point temperature to control the operating status of the air conditioner based on this, so that the air conditioner is in a variable shunt state. Switch between and fixed shunt state to change the shunt state of the heat exchanger to avoid condensation during dehumidification of the air conditioner and improve user experience.

Based on the above embodiment, as shown in Figure 4, the steps of adjusting the air conditioner to a variable split state include:

Step 410: Obtain the current shunt status of the air conditioner.

When the difference between the dew point temperature and the coil temperature is large, obtain the shunt status of the indoor heat exchanger and/or the outdoor heat exchanger of the air conditioner. The shunt status includes: single-way shunt and multi-way shunt.

Step 420: If the air conditioner is in single-channel splitting, adjust to multi-channel splitting to work.

Adjust the shunt status of the heat exchanger to switch between single-way shunt or multi-way shunt. Three or four heat exchange pipelines can be set up as needed, so that the split state can also be set to an intermediate state of partial split to ensure selection according to needs during operation.

If the indoor heat exchanger and/or the outdoor heat exchanger are in single-channel split flow, adjust the indoor heat exchanger and/or outdoor heat exchanger to work in multi-channel split flow to reduce the refrigerant pressure and reduce the subcooling section. If the air conditioner is also equipped with an intermediate device for partial splitting, it can also be adjusted from a single-channel splitting state to a partial splitting state, and use part of the heat exchange pipelines for heat exchange.

Step 430: If the air conditioner is in multi-channel splitting, continue to work in multi-channel splitting.

If the indoor heat exchanger and/or the outdoor heat exchanger are in multi-path splitting, the indoor heat exchanger and/or the outdoor heat exchanger will continue to work in multi-path splitting. If the air conditioner is also equipped with an intermediate state of partial splitting, then in the intermediate state, the splitting of the indoor heat exchanger and/or the outdoor heat exchanger can be increased to reduce the refrigerant pressure and reduce the subcooling section. After adjusting to the variable splitting state, Correct the air conditioner's diversion situation in a timely manner.

After adjusting the single-channel shunt or multi-channel shunt, as shown in Figure 5, it also includes:

Step 440: Obtain the coil temperature of the air conditioner again.

After adjusting the shunt status, the air conditioner obtains the coil temperature again through the sensor.

Step 450: If the coil temperature obtained again is within the second preset interval, continue to adjust the split state of the air conditioner, and return to the step of obtaining the coil temperature of the air conditioner again.

If the coil temperature obtained again is within the second preset interval, continue to adjust the split state of the air conditioner, and return to the step of obtaining the coil temperature of the air conditioner again. Assume that the first preset interval is -3 to 0°C, the second preset interval is below -3°C, and the dew point temperature is 16°C. If the coil temperature obtained again is 10°C, due to the difference between the dew point temperature and the coil temperature If the difference is large, continue to adjust the split state of the air conditioner, return to the step of obtaining the coil temperature of the air conditioner again, and continue to adjust the split state. For example, when the air conditioner has a total of three branches, you can first use a single branch. If it is found that the difference between the dew point temperature and the coil temperature is large, adjust it to a two-way branch. If the difference between the dew point temperature and the coil temperature is still large, If it is large, adjust it to a three-way split.

Step 460: If the coil temperature obtained again is within the first preset interval, stop adjusting the split state of the air conditioner.

If the coil temperature obtained again is within the first preset interval, the adjustment of the split state of the air conditioner is stopped. For example, assume that the first preset interval is -3 to 0°C, the second preset interval is below -3°C, and the dew point temperature is 16°C. If the obtained coil temperature is 15°C, it means that the adjusted dew point temperature is The difference in coil temperature is small. During the process of heat exchange between the air conditioner and the indoor air, condensation is less likely to occur on other parts of the air conditioner. The air conditioner can dehumidify normally. There is no need to adjust the split state of the air conditioner. Then adjust the air conditioner to the fixed split state. .

When the shunt cannot be avoided by adjusting the shunt status, the coil temperature of the air conditioner can be obtained again. Based on the coil temperature obtained again, the indoor fan speed is adjusted.

Specifically, if the coil temperature obtained again is within the second preset interval, the rotation speed of the indoor fan can be increased. If the coil temperature obtained again is within the first preset interval, the rotation speed of the indoor fan can be kept unchanged or reduced.

For example, assume that the first preset interval is -3 to 0°C, the second preset interval is below -3°C, and the dew point temperature is 16°C. If the obtained coil temperature is 15°C, it means that the adjusted dew point temperature is If the difference in coil temperature is small, keep the indoor fan speed unchanged or reduce the speed. When the coil temperature obtained again is 10°C, it means that the difference between the dew point temperature and the coil temperature after adjustment is large, so the indoor fan speed is increased.
