With reference to FIG. 1 , an embodiment of the present disclosure provides a method for preventing condensation on an air-conditioning panel. The air-conditioning panel is provided with a heating device, and the method includes:

S01. Detect indoor environmental humidity;

S02, adjust the heating power of the heating device according to the indoor ambient humidity, so as to heat the air-conditioning panel to prevent condensation.

During the cooling operation of the air conditioner, the temperature of the air conditioner panel will be lower than the indoor ambient temperature. When the panel temperature is lower than the dew point temperature, condensation will appear on the air conditioner panel, especially for metal air conditioner panels, condensation is more likely to occur. Phenomenon. A heating device is arranged on the air-conditioning panel, so that the heating device heats the air-conditioning panel and raises the temperature of the air-conditioning panel, thereby avoiding the occurrence of condensation. The heating device may be an electric heating sheet, and the air conditioning panel is heated by energizing the electric heating sheet. Electric heaters are easy to set up on the air conditioning panel. The heating device can adjust its heating power. When the heating power is large, the heating power of the air-conditioning panel is large. Similarly, when the heating power is small, the heating power of the air-conditioning panel is small. Exemplarily, as shown in FIG. 2 , the air conditioner includes an air conditioner panel 10 . The air conditioner panel 10 is provided with an air outlet grille 11 , and a temperature sensor 50 and an electric heating plate are provided on the air conditioner panel near the air outlet grille. The temperature sensor 50 is configured as The temperature of the air conditioner panel is detected, and the electric heater is configured to heat the air conditioner panel 10 . As shown in FIG. 3 , optionally, the electric heating sheet 30 is arranged on the inner side of the air conditioning panel 10 . It can also be used to heat the air conditioning panel 10 and avoid affecting the appearance of the air conditioning panel. Optionally, the air conditioner is a vertical air conditioner, including a column 40 .

When the indoor ambient humidity reaches a certain level, for example, there is a lot of moisture in the air, when the air is in contact with the air-conditioning panel, if the temperature of the air-conditioning panel is lower than the dew point temperature, the moisture will easily form condensation on the surface of the air-conditioning panel. Indoor ambient humidity also affects the ease of condensation of indoor air on the air conditioner panel. The heating power of the heating device can be adjusted according to the indoor ambient humidity, so that the air conditioner panel can avoid condensation in various indoor ambient humidity, and the heating device The power can be converted between large and small, and the energy consumption is reduced compared to the use of larger heating power for anti-condensation heating.

The humidity of the indoor environment can be detected by setting a humidity sensor on the air conditioner. The heating power of the heating device can be controlled by arranging a thermostat to electrically connect the thermostat to the heating device. Specifically, the temperature controller controls the input and output signals, and the thyristor adjusts the heating power of the heating device to control the heating amount of the heating device. When the thyristor outputs full power, the heating device is in a full power working state.

In some embodiments, adjusting the heating power of the heating device according to the indoor ambient humidity includes:

When the indoor ambient humidity is greater than or equal to the preset humidity, adjust the heating device to operate at the first power or the second power according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature; and/or,

When the indoor ambient humidity is lower than the preset humidity, according to the comparison result of the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature, adjust the heating device to operate at the first power or keep the operation of the heating device unchanged;

Wherein, the first power is smaller than the second power.

The preset humidity is a standard for measuring indoor environmental humidity. When the indoor environmental humidity is less than the preset humidity, the indoor environmental humidity is considered to be low, and when the indoor environmental humidity is greater than or equal to the preset humidity, the indoor environmental humidity is considered to be high. When the indoor ambient humidity is greater than or equal to the preset temperature, adjust the heating device to run at the first power or the second power according to the comparison result of the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature; when the indoor ambient humidity is lower than the preset temperature When setting the humidity, according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, the heating device is adjusted to operate at the first power or the operation of the heating device is kept unchanged. That is, when the indoor ambient humidity is relatively high, the heating device operates at the first power or the second power, and when the indoor ambient humidity is relatively low, the heating device operates at the smaller one of the first power and the second power. One power operation, or keep the operation of the heating device unchanged. In this way, in some cases, the heating power of the heating device does not need to be too high, so that condensation can be avoided and energy consumption can be reduced.

Keeping the operation of the heating device unchanged means that if the heating device is already in the heating state, the current heating power is kept unchanged, or if the heating device is not heating, the non-operating state of the heating device is kept unchanged. Optionally, when the indoor ambient humidity is greater than or equal to the preset humidity, if the air conditioner panel temperature is greater than the indoor ambient temperature and the indoor ambient temperature is greater than the preset dew point temperature, the operation of the heating device is kept unchanged. Because, at this time, the air-conditioning panel is not easy to condense, and it can be heated or not heated.

Optionally, the first power is 150W, and the second power is 300W. When the first and second powers adopt this value, the heating power can be adjusted more appropriately for the heating device.

The preset humidity uses relative humidity. Optionally, the preset humidity is 50%. The indoor environmental humidity is compared with the preset humidity to determine the degree of indoor environmental humidity, and further control is performed according to the comparison result.

Optionally, the preset dew point temperature and the dew point temperature of the air conditioning panel satisfy the following relationship:

TL'=TL+Δt, where TL' is the preset dew point temperature, TL is the dew point temperature of the air-conditioning panel, Δt>0.

According to the above calculation formula, the preset dew point temperature can be calculated according to the dew point temperature. It can be seen that the preset dew point temperature is higher than the dew point temperature, and the preset dew point temperature is compared with the indoor ambient temperature and the temperature of the air conditioner panel, instead of directly comparing the dew point temperature with the two, so as to avoid adjusting the heating power of the heating device to an appropriate value. Condensation has started on the front air conditioning panel. Optionally, Δt=1. With this Δt value, the heating device can be adjusted to avoid condensation on the air-conditioning panel.

Exemplarily, as shown in FIG. 4 , adjusting the heating power of the heating device according to the indoor ambient humidity includes:

S03, determine whether the indoor environmental humidity is greater than or equal to the preset humidity, if yes, go to step S04; if not, go to step S05;

S04, adjusting the heating device to operate at the first power or the second power according to the comparison result of the air-conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature;

S05. According to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, adjust the heating device to operate at the first power or keep the operation of the heating device unchanged.

Through this embodiment, the heating device is adjusted to heat the air-conditioning panel, thereby increasing the temperature of the air-conditioning panel, thereby avoiding the occurrence of condensation.

In some embodiments, adjusting the heating device to operate at the first power or the second power according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, including:

In the case where the minimum value between the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature is the air conditioner panel temperature, according to the comparison result between the indoor ambient temperature and the preset dew point temperature, adjust the heating device to use the first power or the second power run.

When the minimum value between the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature is the air conditioner panel temperature, it indicates that the air conditioner panel temperature is at least lower than one of the indoor ambient temperature and the preset dew point temperature, especially when the air conditioner panel temperature is not only lower than When the indoor ambient temperature is still lower than the preset dew point temperature, even when the indoor ambient humidity is low, the air conditioner panel tends to condense. Warm up the heating unit to avoid condensation on the air conditioning panels. Specifically, whether to run with the first or second power, the indoor ambient temperature and the preset dew point temperature can be further compared, and the power can be selected according to the comparison result, so as to make the adjustment more accurate. Optionally, the rotational speed of the indoor fan is adjusted to decrease relative to the default rotational speed of the indoor fan. In this way, condensation can be avoided by reducing the cooling intensity of the air conditioner. The default speed of the indoor fan can be 960rpm/min, and the speed of the indoor fan can be reduced to 850rpm/min, 700rpm/min or 600rpm/min.

In some embodiments, adjusting the heating device to operate at the first power or the second power according to the comparison between the indoor ambient temperature and the preset dew point temperature, including:

When the indoor ambient temperature is greater than the preset dew point temperature, adjusting the heating device to run at the first power;

When the indoor ambient temperature is lower than the preset dew point temperature, the heating device is adjusted to operate at the second power.

In the case where the temperature of the air conditioner panel is the smallest among the three, if the indoor ambient temperature is greater than the preset dew point temperature, it means that the indoor ambient temperature has not fallen below the preset dew point temperature, and only the air conditioner panel temperature is below the preset dew point temperature. At this time, the first power can be used for heating, and the first power is smaller than the second power, which also means that under the influence of the indoor ambient temperature, the dew condensation tendency of the air-conditioning panel is lower than the preset dew point temperature than the indoor ambient temperature. The air-conditioning panel has a smaller tendency to condensation and can be heated with a smaller power. When the indoor ambient temperature is lower than the preset dew point temperature, it indicates that the dew condensation tendency of the air conditioning panel increases, and a heating power higher than the first power should be used for heating.

In some embodiments, when the indoor ambient temperature is lower than the preset dew point temperature, the method further includes: adjusting the indoor ambient temperature to a preset temperature.

When the indoor ambient temperature is lower than the preset dew point temperature, it indicates that the indoor ambient temperature is also low, and the air conditioner panel is prone to condensation. The condensation tendency of the air-conditioning panel is weakened, so that the value of the second power of the heating device can also be set at a position larger than the first power value, but lower, which is beneficial to reduce the energy consumption of the heating device. Optionally, the preset temperature T=Tr-3, where Tr is the indoor ambient temperature. Optionally, T > 16°C. In this way, by adjusting the indoor ambient temperature, the air conditioner operates in the maximum dehumidification state, and cooperates with the heating of the heating device to avoid condensation on the air conditioner panel.

In some embodiments, adjusting the heating device to operate at the first power or the second power according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, further comprising:

When the indoor ambient temperature is greater than the temperature of the air-conditioning panel, and the temperature of the air-conditioning panel is greater than the preset dew point temperature, the heating device is adjusted to operate at the first power.

If the indoor ambient temperature is greater than the air conditioner panel temperature, and the air conditioner panel temperature is greater than the preset dew point temperature, that is, the air conditioner panel temperature is between the indoor ambient temperature and the preset dew point temperature, indicating that the condensation tendency of the air conditioner panel is not very large, and the first method can be used. One power for heating to avoid condensation on the air conditioning panel.

In some embodiments, according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, adjusting the heating device to operate at the first power or keeping the heating device running unchanged, including:

In the case that the maximum value between the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature is the indoor ambient temperature, adjusting the heating device to operate at the first power; or,

When the preset dew point temperature is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the temperature of the air-conditioning panel, adjusting the heating device to operate at the first power;

When the temperature of the air-conditioning panel is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the preset dew point temperature, the operation of the heating device is kept unchanged.

In the case where the maximum value between the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature is the preset dew point temperature, it indicates that at least one of the air conditioning panel temperature and the indoor ambient temperature is lower than the preset dew point temperature, and the other may be It is the same as the preset dew point temperature, or both are lower than the preset dew point temperature. At this time, combined with the indoor ambient humidity is lower than the preset humidity, the indoor ambient humidity is small, and the tendency of condensation on the air conditioner panel is not very large. Adjust the heating device to the first one. One power operation, that is, heating the air conditioner panel with a smaller heating power to avoid condensation. When the preset dew point temperature is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the temperature of the air conditioner panel, the heating device can be adjusted to operate at the first power to heat the air conditioner panel. When the temperature of the air-conditioning panel is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the preset dew point temperature, the air-conditioning panel is not easy to condense, and the operation of the heating device can be kept unchanged. That is, if the heating device is heating, the heating can be maintained. If the heating device does not start heating, it can continue to maintain the unheated state.

Optionally, the rotational speed of the indoor fan is adjusted to decrease relative to the default rotational speed of the indoor fan. In this way, condensation can be avoided by reducing the cooling intensity of the air conditioner. The default speed of the indoor fan can be 960rpm/min, and the speed of the indoor fan can be reduced to 900rpm/min. By reducing the speed of the indoor fan, it is conducive to dehumidification, and with the heating device running at the first power, the temperature of the air-conditioning panel is increased to avoid condensation.

In some embodiments, after detecting the indoor environmental humidity, the method further includes: adjusting the rotational speed of the indoor fan according to the indoor environmental humidity.

Combining the adjustment of the speed of the indoor fan and the adjustment of the heating power of the heating device enables the auxiliary heating device to prevent condensation by adjusting the speed of the indoor fan when the air conditioner is running, which is also conducive to reducing the energy consumption of the heating device.

With reference to FIG. 5 , an embodiment of the present disclosure provides a method for preventing condensation on an air-conditioning panel, including:

S01. Detect indoor environmental humidity;

S12. Adjust the rotational speed of the indoor fan according to the indoor ambient humidity to prevent condensation on the air-conditioning panel.

During the cooling operation of the air conditioner, the temperature of the air conditioner panel will be lower than the indoor ambient temperature. When the panel temperature is below the dew point temperature, condensation will appear on the air conditioner panel, especially for metal air conditioner panels, condensation is more likely to occur. dew phenomenon. The speed of the indoor fan of the air conditioner can be adjusted to affect the humidity of the air flowing out of the air outlet of the air conditioner to avoid condensation. During the cooling process of the air conditioner, if the indoor fan rotates at the default speed, when the air with a lower temperature is blown out from the air conditioner, combined with the indoor ambient humidity, it may cause condensation on the air conditioner panel. If the speed of the indoor fan is appropriately reduced, the air conditioner enters the dehumidification process. , to avoid condensation on the air-conditioning panel.

Optionally, the air conditioning panel is provided with a heating device, and the heating device is configured to heat the air conditioning panel to prevent condensation. The speed of the indoor fan and the power of the heating device can be adjusted according to the indoor ambient humidity, and synergistic effects can be achieved from different aspects to avoid condensation on the air-conditioning panel. The heating device may be an electric heating sheet, and the air conditioning panel is heated by energizing the electric heating sheet. When the heating power of the heating device is large, the heating power of the air-conditioning panel is large, and when the heating power is small, the heating power of the air-conditioning panel is small.

In some embodiments, adjusting the rotational speed of the indoor fan according to the indoor environment includes:

When the indoor ambient humidity is greater than or equal to the preset humidity, according to the comparison result between the air-conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, adjust the indoor fan at the first rotation speed, or adjust the indoor fan at the second rotation speed and the first rotation speed. Switch operation between three speeds; and/or,

When the indoor ambient humidity is lower than the preset humidity, adjust the indoor fan to run at the fourth speed or keep the indoor fan running unchanged according to the comparison result of the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature;

The first rotational speed is greater than the fourth rotational speed, the fourth rotational speed is greater than the second rotational speed, and the second rotational speed is greater than the third rotational speed.

The preset humidity is a standard line for measuring the indoor environmental humidity. When the indoor environmental humidity is less than the preset humidity, the indoor environmental humidity is considered to be low, and when the indoor environmental humidity is greater than or equal to the preset humidity, the indoor environmental humidity is considered to be high. When the indoor ambient humidity is greater than or equal to the preset temperature, according to the comparison result of the air-conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, adjust the indoor fan at the first rotation speed, or adjust the indoor fan at the second rotation speed and the first rotation speed. Switch operation between three speeds. The first to third rotational speeds are all lower than the default rotational speed of the indoor fan in the cooling state, and the default rotational speed may be 960 rpm/min. When the indoor environmental humidity is high, according to the comparison results of each temperature, the indoor fan speed is adjusted from the default speed to a different value, which is conducive to the dehumidification process and prevents condensation on the air conditioner panel through dehumidification. The indoor fan speed switches between the second and third speeds because the second and third speeds are the best dehumidification speeds, and entering the third speed is more conducive to dehumidification. It is relatively low, and continuous operation at the third speed is likely to cause protection phenomenon, so the indoor fan speed is switched between the second and third speeds.

Optionally, when the rotational speed of the indoor fan is adjusted to operate at the first rotational speed, the heating device is adjusted to operate at the first power. Compared with the second to fourth speeds, the first speed is the closest to the default speed, that is, the speed reduction is not large. At this time, the first power heating of the heating device is used to dehumidify and heat to avoid condensation on the air conditioner panel.

Optionally, when the rotational speed of the indoor fan is adjusted to switch between the second rotational speed and the third rotational speed, the heating device is adjusted to operate at the second power. At this time, the cooperation of the heating device and the indoor fan can enhance the anti-condensation effect.

When the indoor ambient humidity is lower than the preset humidity, according to the comparison result of the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature, adjust the indoor fan to run at the fourth speed or keep the indoor fan running unchanged. When the indoor ambient humidity is low, the indoor fan rotates at a fourth rotation speed between the first and the second rotation speed, or keeps the operation of the indoor fan unchanged. In this way, in some cases, the heating power of the heating device does not need to be too high, so that condensation can be avoided and energy consumption can be reduced.

Optionally, the first to fourth rotational speeds are all lower than the default rotational speed in the cooling state of the indoor fan. That is, the rotational speed of the indoor fan is reduced to different degrees to increase the temperature of the air-conditioning panel. Optionally, the default rotational speed is 960 rpm/min. When the air conditioner is cooling normally, the indoor fan speed is 960rpm/min. Optionally, the first rotational speed is 850 rpm/min, the second rotational speed is 700 rpm/min, the third rotational speed is 600 rpm/min, and the fourth rotational speed is 800 rpm/min. The indoor fan rotates at the above-mentioned rotational speed, which can prevent the temperature of the air-conditioning panel from being lower than the dew point temperature, thereby avoiding condensation on the air-conditioning panel.

In some embodiments, according to the comparison result between the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, the indoor fan is adjusted to operate at the first rotational speed, or the indoor fan is adjusted to switch between the second rotational speed and the third rotational speed ,include:

When the temperature of the air-conditioning panel is the smallest among the three, it means that the temperature of the air-conditioning panel is relatively low and condensation is easy. Lowering the speed of the indoor fan is beneficial to dehumidification and avoid condensation. The rotational speed of the indoor fan can be the first rotational speed, or switch operation between the second rotational speed and the third rotational speed, which can increase the temperature of the air conditioner panel to prevent condensation. Specifically, whether to switch between the first rotation speed or the second rotation speed and the third rotation speed can be further determined according to the indoor ambient temperature and the preset dew point temperature.

In some embodiments, according to the comparison result between the indoor ambient temperature and the preset dew point temperature, adjusting the indoor fan to operate at the first rotation speed, or adjusting the indoor fan to switch between the second rotation speed and the third rotation speed, including:

When the indoor ambient temperature is greater than or equal to the preset dew point temperature, adjust the indoor fan to run at the first speed;

When the indoor ambient temperature is lower than the preset dew point temperature, the indoor fan is adjusted to switch between the second rotational speed and the third rotational speed.

When the temperature of the air conditioner panel is the smallest among the three, if the indoor ambient temperature is greater than or equal to the preset dew point temperature, it means that the indoor ambient temperature has not fallen below the preset dew point temperature, and only the air conditioner panel temperature is below the preset dew point temperature. , at this time, the indoor fan can use the first speed. If the indoor ambient temperature is lower than the preset dew point temperature, it means that the air conditioner panel is easy to condense, and the indoor fan can switch between the second speed and the third speed. , Under the influence of the indoor ambient temperature, the indoor ambient temperature higher than the preset dew point temperature can make the condensation tendency of the air conditioner panel smaller than that when the indoor ambient temperature is lower than the preset dew point. , the rotational speed of the indoor fan is reduced to a lesser degree, and the first rotational speed is used. The first rotational speed is higher than the second rotational speed, the second rotational speed is higher than the third rotational speed, and the switching operation between the second rotational speed and the third rotational speed means that the indoor fan can use a lower rotational speed for some time periods and a lower rotational speed for some time periods. , which is beneficial to the dehumidification process, to avoid condensation on the air conditioning panel, and to reduce the impact on the cooling operation by switching the speed. The second rotational speed was 700 rpm/min, and the third rotational speed was 600 rpm/min. That is, the indoor fan was switched and operated at the rotational speed of 600 rpm/min and 700 rpm/min.

In some embodiments, when the indoor ambient temperature is lower than the preset dew point temperature, the method further includes: adjusting the indoor ambient temperature to a preset temperature.

When the indoor ambient temperature is lower than the preset dew point temperature, it indicates that the indoor ambient temperature is also low, and the air conditioner panel is prone to condensation. To reduce the condensation tendency of the air-conditioning panel, optionally, the preset temperature T=Tr-3, where Tr is the indoor ambient temperature. Optionally, T > 16°C. In this way, by adjusting the indoor ambient temperature, the air conditioner operates in the maximum dehumidification state, and cooperates with the operation of the indoor fan to avoid condensation on the air conditioner panel.

In some embodiments, according to the comparison result of the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature, adjusting the indoor fan to run at the fourth rotational speed or keeping the indoor fan running unchanged, including:

Under the condition that the maximum value between the air conditioning panel temperature, the indoor ambient temperature and the preset dew point temperature is the indoor ambient temperature, adjust the indoor fan to run at the fourth rotational speed;

When the temperature of the air-conditioning panel is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the preset dew point temperature, the operation of the indoor fan is kept unchanged.

In the case where the maximum value between the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature is the indoor ambient temperature, at this time, combined with the indoor ambient humidity being less than the preset humidity, the indoor ambient humidity is relatively small, and the air conditioner panel has a general tendency to condense. , so that the indoor fan runs at the fourth speed, that is, the speed of the indoor fan is smaller than the default speed during cooling, but lower than the first speed to avoid condensation. When the temperature of the air-conditioning panel is greater than the indoor ambient temperature, and the indoor ambient temperature is greater than the preset dew point temperature, the air-conditioning panel is not easy to condense, and the operation of the indoor fan can be kept unchanged, so that condensation will not occur on the air-conditioning panel.
