Referring to fig. 1, an embodiment of the present disclosure provides a method for preventing condensation of an air conditioner panel, where the air conditioner panel is provided with a heating device, and the method includes:
s01, detecting the indoor environment humidity;
and S02, adjusting the heating power of the heating device according to the indoor environment humidity so as to heat the air-conditioning panel to prevent condensation.
At the in-process of air conditioner refrigeration operation, the temperature of air conditioner panel can be less than indoor environment temperature, and when the panel temperature was less than dew point temperature, the condensation phenomenon can appear on the air conditioner panel, especially to the air conditioner panel of metal material, the condensation phenomenon appears more easily. Set up heating device at the air conditioner panel, make heating device heat the air conditioner panel, promote the temperature of air conditioner panel to avoid the production of condensation phenomenon. The heating means may be an electric heating sheet which is heated by energizing the electric heating sheet to the air-conditioning panel. The electric heating sheet is easily provided at the air conditioner panel. Heating device can adjust its heating power, and when heating power was great, it was great to the heating dynamics of air conditioner panel, and in the same way, when heating power was less, the heating dynamics to the air conditioner panel was on the small side. Exemplarily, as shown in fig. 2, the air conditioner includes an air conditioning panel 10, the air conditioning panel 10 is provided with an air outlet grill 11, a portion of the air conditioning panel near the air outlet grill is provided with a temperature sensor 50 and an electric heating sheet, the temperature sensor 50 is configured to detect a temperature of the air conditioning panel, and the electric heating sheet is configured to heat the air conditioning panel 10. As shown in connection with fig. 3, an electric heating sheet 30 is optionally provided at 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. Alternatively, the air conditioner is a floor air conditioner, including the pillar 40.
When the indoor environment humidity reaches a certain degree, for example, the air has more moisture, when the air contacts with the air-conditioning panel, if the temperature of the air-conditioning panel is lower than the dew point temperature, the moisture is liable to form condensation on the surface of the air-conditioning panel. Indoor environment humidity also influences the condensation degree of room air at air conditioner panel, can adjust heating device's heating power according to indoor environment humidity, makes air conditioner panel can avoid the condensation in various indoor environment humidity, and heating device's power can change between the size, compares and adopts great heating power always to prevent the condensation heating, and the energy consumption reduces.
The humidity sensor can be arranged on the air conditioner to detect the indoor environment humidity. The temperature controller can be electrically connected with the heating device to control the heating power of the heating device by arranging the temperature controller. Specifically, the temperature controller controls input and output signals, and the heating power of the heating device is adjusted by the controllable silicon to control the heating quantity of the heating device. When the controllable silicon outputs full power, the heating device is in a full-power working degree state.
In some embodiments, adjusting the heating power of the heating device according to the indoor ambient humidity comprises:
when the indoor environment humidity is greater than or equal to the preset humidity, adjusting the heating device to operate at a first power or a second power according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature; and/or the presence of a gas in the gas,
when the indoor environment humidity is less than the preset humidity, adjusting the heating device to operate at a first power or keeping the operation of the heating device unchanged according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature;
wherein the first power is less than the second power.
The preset humidity is a standard for measuring the indoor environment humidity, when the indoor environment humidity is less than the preset humidity, the indoor environment humidity is considered to be lower, and when the indoor environment humidity is greater than or equal to the preset humidity, the indoor environment humidity is considered to be higher. Under the condition that the indoor environment humidity is greater than or equal to the preset temperature, adjusting the heating device to operate at a first power or a second power according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature; when the indoor environment humidity is less than the preset humidity, the heating device is adjusted to operate at the first power or the operation of the heating device is kept unchanged according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature. That is, in the case where the indoor ambient humidity is relatively large, the heating device is operated at the first power or the second power, and in the case where the indoor ambient humidity is relatively small, the heating device is operated at the first power which is smaller of the first power and the second power, or the operation of the heating device is kept unchanged. Therefore, in some cases, the heating power of the heating device is not required to be too high, condensation can be avoided, and energy consumption is reduced.
The operation of the heating device is kept unchanged, that is, the current heating power is kept unchanged if the heating device is already in the heating state, or the heating device is kept in the non-operating state if the heating device is not heating. Optionally, when the indoor environment humidity is greater than or equal to the preset humidity, if the air conditioner panel temperature is greater than the indoor environment temperature and the indoor environment temperature is greater than the preset dew point temperature, the operation of the heating device is kept unchanged. Because the air conditioner panel is not easy to be condensed at the moment, the air conditioner panel can be heated or not heated.
Optionally, the first power is 150W and the second power is 300W. By adopting the values of the first and second powers, the heating power of the heating device can be adjusted more appropriately.
The preset humidity is relative humidity. Optionally, the preset humidity is 50%. And comparing the indoor environment humidity with the preset humidity to judge the degree of the indoor environment humidity, and further controlling according to the comparison result.
Optionally, the preset dew point temperature and the dew point temperature of the air conditioner panel satisfy the following relationship:
TL ═ TL + [ delta ] t, wherein TL' is the preset dew point temperature, TL is the dew point temperature of the air conditioning panel, and [ delta ] t is more than 0.
According to the 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 environment temperature and the air conditioner panel temperature instead of directly comparing the dew point temperature with the indoor environment temperature and the air conditioner panel temperature, so that the phenomenon that the air conditioner panel begins to condense before the heating power of the heating device is adjusted to a proper value is avoided. Optionally, Δ t ═ 1. By adopting the delta t value, the heating device can be adjusted, and condensation of the air conditioner panel is avoided.
Illustratively, as shown in fig. 4, the adjusting of the heating power of the heating device according to the indoor ambient humidity includes:
s03, judging whether the indoor environment humidity is larger than or equal to the preset humidity, if so, executing a step S04; if not, go to step S05;
s04, adjusting the heating device to operate at a first power or a second power according to the comparison result of the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature;
and S05, adjusting the heating device to operate at the first power or keeping the operation of the heating device unchanged according to the comparison result of the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature.
Through this embodiment, adjust heating device and heat the air conditioner panel, promote the temperature of air conditioner panel to avoid the production of condensation phenomenon.
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 conditioner panel temperature, the indoor ambient temperature, and the preset dew point temperature includes:
and under the condition that the minimum value among the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature is the temperature of the air conditioner panel, adjusting the heating device to operate at the first power or the second power according to the comparison result of the indoor environment temperature and the preset dew point temperature.
When the minimum value between the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature is the air conditioner panel temperature, the fact that the air conditioner panel temperature is at least lower than one of the indoor environment temperature and the preset dew point temperature is shown, especially when the air conditioner panel temperature is not only lower than the indoor environment temperature but also lower than the preset dew point temperature, even under the condition that the indoor environment humidity is small, the air conditioner panel tends to be condensed, at the moment, the heating device is adjusted to operate at the first power or the second power, the heating device is heated, and therefore condensation of the air conditioner panel is avoided. Particularly, the power control system runs at the first power or the second power, the indoor environment temperature and the preset dew point temperature can be further compared, and the power is selected according to the comparison result, so that the adjustment is more accurate. Optionally, the indoor fan speed is adjusted to be reduced relative to a default indoor fan speed. In this way, condensation can be avoided by reducing the cooling intensity of the air conditioner. The default speed of the indoor fan may be 960rpm/min, and the speed of the indoor fan may be reduced to 850rpm/min, 700rpm/min or 600 rpm/min.
In some embodiments, adjusting the heating device to operate at the first power or the second power according to the comparison of the indoor ambient temperature and the preset dew point temperature includes:
when the indoor environment temperature is higher than the preset dew point temperature, adjusting the heating device to operate at a first power;
and when the indoor environment temperature is lower than the preset dew point temperature, adjusting the heating device to operate at a second power.
Under the condition that the temperature of the air-conditioning panel is the minimum among the three, if the indoor environment temperature is greater than the preset dew point temperature, the fact that the indoor environment temperature is not lower than the preset dew point temperature is indicated, only the temperature of the air-conditioning panel is lower than the preset dew point temperature, at the moment, the first power can be adopted for heating, the first power is smaller than the second power, the fact that under the influence of the indoor environment temperature, the condensation tendency of the air-conditioning panel is smaller than that under the condition that the indoor environment temperature is lower than the preset dew point temperature is also meant, and the air-conditioning panel can be heated by adopting smaller power. When the indoor environment temperature is lower than the preset dew point temperature, the condensation tendency of the air conditioner panel is increased, and the heating power higher than the first power is adopted for heating.
In some embodiments, when the indoor ambient temperature is less than the preset dew point temperature, the method further comprises: and adjusting the indoor environment temperature to a preset temperature.
When the indoor environment temperature is lower than the preset dew point temperature, the indoor environment temperature is lower, condensation can easily occur on the air conditioner panel, at the moment, the indoor environment temperature is adjusted to the preset temperature, the air conditioner is enabled to operate in the maximum dehumidification state, the condensation tendency of the air conditioner panel is favorably weakened, and therefore the numerical value of the second power of the heating device can be set to be larger than the first power numerical value, but the energy consumption of the heating device is favorably reduced on the lower position. Optionally, the preset temperature T ═ Tr-3, where Tr is the indoor ambient temperature. Alternatively, T.gtoreq.16 ℃. Like this, through adjusting indoor ambient temperature, make the air conditioner with the operation of maximum dehumidification state, the heating of cooperation heating device avoids air conditioner panel condensation.
In some embodiments, adjusting the heating device to operate at the first power or the second power according to a comparison result of the air conditioner panel temperature, the indoor ambient temperature, and the preset dew point temperature further includes:
when the indoor environment temperature is higher than the temperature of the air conditioner panel and the temperature of the air conditioner panel is higher than the preset dew point temperature, the heating device is adjusted to operate at a first power.
If the indoor environment temperature is greater than the air conditioner panel temperature, the air conditioner panel temperature is greater than the preset dew point temperature again, namely the air conditioner panel temperature is between the indoor environment temperature and the preset dew point temperature, the condensation tendency of the air conditioner panel is not very large, and the air conditioner panel can be heated by adopting the first power to avoid condensation of the air conditioner panel.
In some embodiments, adjusting the heating device to operate at the first power or keeping the operation of the heating device constant according to the comparison result of the air conditioner panel temperature, the indoor ambient temperature and the preset dew point temperature includes:
under the condition that the maximum value among the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature is the indoor environment temperature, adjusting the heating device to operate at a first power; alternatively, the first and second electrodes may be,
under the condition that the preset dew point temperature is higher than the indoor environment temperature and the indoor environment temperature is higher than the temperature of the air conditioner panel, adjusting the heating device to operate at a first power;
and when the temperature of the air conditioner panel is higher than the indoor environment temperature and the indoor environment temperature is higher than the preset dew point temperature, keeping the operation of the heating device unchanged.
Under the condition that the maximum value between the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature is the preset dew point temperature, it is shown that at least one of the temperature of the air conditioner panel and the indoor environment temperature is smaller than the preset dew point temperature, the other one of the temperature of the air conditioner panel and the indoor environment temperature is possibly the same as the preset dew point temperature, or both the temperature of the air conditioner panel and the preset dew point temperature are smaller than the preset dew point temperature. When the preset dew point temperature is higher than the indoor environment temperature and the indoor environment temperature is higher than the temperature of the air conditioner panel, the heating device can be adjusted to operate at a first power to heat the air conditioner panel. Under the condition that the temperature of the air conditioner panel is greater than the indoor environment temperature and the indoor environment temperature is greater than the preset dew point temperature, the air conditioner panel is not prone to condensation, the operation of the heating device can be kept unchanged, namely, if the heating device is heating, the heating state can be kept, and if the heating device is not started for heating, the non-heating state can be kept continuously.
Optionally, the indoor fan speed is adjusted to be reduced relative to a default indoor fan speed. In this way, condensation can be avoided by reducing the cooling intensity of the air conditioner. The default speed of the indoor fan may be 960rpm/min, and the speed of the indoor fan may be reduced to 900 rpm/min. Through reducing indoor fan rotational speed, be favorable to the dehumidification, cooperation heating device makes air conditioner panel temperature rise with first power operation, avoids the condensation.
In some embodiments, after detecting the indoor ambient humidity, the method further comprises: and adjusting the rotating speed of the indoor fan according to the indoor environment humidity.
The regulation of the rotating speed of the indoor fan and the regulation of the heating power of the heating device are combined, so that when the air conditioner operates, the auxiliary heating device prevents condensation through regulating the rotating speed of the indoor fan, and the energy consumption of the heating device is reduced.
Referring to fig. 5, an embodiment of the present disclosure provides a method for preventing condensation on an air conditioner panel, including:
s01, detecting the indoor environment humidity;
and S12, adjusting the rotating speed of the indoor fan according to the indoor environment humidity to prevent the air conditioner panel from being condensed.
In the process of air conditioner refrigeration operation, the temperature of the air conditioner panel can be lower than the indoor environment temperature, when the temperature of the panel is lower than the dew point temperature, the condensation phenomenon can occur on the air conditioner panel, and particularly, the condensation phenomenon can occur more easily on the air conditioner panel made of metal. The rotating speed of the indoor fan of the air conditioner can be adjusted, so that the humidity of the air flow flowing out of the air outlet of the air conditioner is influenced, and the condensation phenomenon is avoided. In the air conditioner refrigeration process, if the indoor fan rotates according to the default rotating speed, when the air flow with lower temperature is blown out from the air conditioner, the condensation of the air conditioner panel can be caused by combining the indoor environment humidity, and if the rotating speed of the indoor fan is properly reduced, the air conditioner enters the dehumidification process, so that the condensation of the air conditioner panel can be avoided.
Optionally, the air conditioning panel is provided with a heating device configured to heat the air conditioning panel to prevent condensation. Can be according to indoor environment humidity control room fan rotational speed and heating device's power, from different aspects synergism, avoid air conditioner panel condensation. The heating means may be an electric heating sheet which is heated by energizing the electric heating sheet to the air-conditioning panel. When the heating power of the heating device is larger, the heating power to the air conditioner panel is larger, and when the heating power is smaller, the heating power to the air conditioner panel is smaller.
In some embodiments, adjusting the rotational speed of the indoor fan according to the indoor environment includes:
when the indoor environment humidity is greater than or equal to the preset humidity, adjusting the indoor fan to operate at a first rotating speed or adjusting the indoor fan to operate in a switching mode between a second rotating speed and a third rotating speed according to a comparison result among the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature; and/or the presence of a gas in the gas,
when the indoor environment humidity is lower than the preset humidity, the indoor fan is adjusted to operate at a fourth rotating speed or the operation of the indoor fan is kept unchanged according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature;
the first rotating speed is greater than the fourth rotating speed, the fourth rotating speed is greater than the second rotating speed, and the second rotating speed is greater than the third rotating speed.
The preset humidity is a standard line for measuring the indoor environment humidity, when the indoor environment humidity is less than the preset humidity, the indoor environment humidity is considered to be lower, and when the indoor environment humidity is greater than or equal to the preset humidity, the indoor environment humidity is considered to be higher. And under the condition that the indoor environment humidity is greater than or equal to the preset temperature, adjusting the indoor fan to operate at a first rotating speed or adjusting the indoor fan to switch between a second rotating speed and a third rotating speed according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature. The first to third rotation speeds are all smaller than a default rotation speed of the indoor fan in a refrigeration state, and the default rotation speed can be 960 rpm/min. When indoor environment humidity is great, according to the comparative result of each temperature, with the indoor fan rotational speed from acquiescence rotational speed turn down to different numerical values, be favorable to carrying out the dehumidification process, prevent the condensation of air conditioner panel through the dehumidification. The reason why the indoor fan rotates between the second rotating speed and the third rotating speed is switched to operate is that the second rotating speed and the third rotating speed are the best dehumidifying rotating speed, and the third rotating speed is more favorable for dehumidifying.
Optionally, the indoor fan speed is adjusted to operate at a first speed, and the heating device is adjusted to operate at a first power. Compare second to fourth rotational speed, first rotational speed is the nearest acquiescence rotational speed, and rotational speed reduction degree is little promptly, and the first power heating of cooperation heating device this moment is followed dehumidification and two aspects effects of heating, avoids the condensation of air conditioner panel.
Optionally, when the indoor fan speed is adjusted to switch between the second speed and the third speed, the heating device is adjusted to operate at the second power. At this moment, the cooperation of heating device and indoor fan can strengthen the effect of preventing the condensation.
And when the indoor environment humidity is less than the preset humidity, adjusting the indoor fan to operate at a fourth rotating speed or keeping the operation of the indoor fan unchanged according to the comparison result of the air conditioner panel temperature, the indoor environment temperature and the preset dew point temperature. Under the condition that the indoor environment humidity is low, the indoor fan rotates at a fourth rotating speed between the first rotating speed and the second rotating speed, or the operation of the indoor fan is kept unchanged. Therefore, in some cases, the heating power of the heating device is not required to be too high, condensation can be avoided, and energy consumption is reduced.
Optionally, the first to fourth rotation speeds are all smaller than the default rotation speed of the indoor fan in the cooling state. Namely, the rotating speed of the indoor fan is reduced to different degrees so as to improve the temperature of the air conditioner panel. Optionally, the default speed is 960 rpm/min. When the air conditioner is normally cooled, the rotating speed of the indoor fan is 960 rpm/min. Optionally, the first rotation speed is 850rpm/min, the second rotation speed is 700rpm/min, the third rotation speed is 600rpm/min, and the fourth rotation speed is 800 rpm/min. The indoor fan rotates at the rotating speed, so that the temperature of the air conditioner panel can be prevented from being lower than the dew point temperature, and condensation of the air conditioner panel is avoided.
In some embodiments, 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 according to a comparison result between the air conditioner panel temperature, the indoor ambient temperature, and the preset dew point temperature includes:
and under the condition that the minimum value among the temperature of the air conditioner panel, the indoor environment temperature and the preset dew point temperature is the temperature of the air conditioner panel, adjusting the indoor fan to operate at a first rotating speed or adjusting the indoor fan to switch between a second rotating speed and a third rotating speed according to the comparison result of the indoor environment temperature and the preset dew point temperature.
The air conditioner panel temperature shows that the air conditioner panel temperature is lower under the minimum condition between the three, and the easy condensation is transferred the rotational speed of indoor fan and is reduced a little, is favorable to the dehumidification, can avoid the condensation. The indoor fan rotating speed can adopt the first rotating speed, or, switch the operation between second rotating speed and third rotating speed, and the homoenergetic makes air conditioner panel temperature have certain promotion, prevents the condensation. Specifically, the first rotating speed or the second and third rotating speeds are switched, and the further determination can be carried out according to the indoor environment temperature and the preset dew point temperature.
In some embodiments, adjusting the indoor fan to operate at a first speed or adjusting the indoor fan to switch between a second speed and a third speed according to the comparison result between the indoor ambient temperature and the preset dew point temperature includes:
when the indoor environment temperature is greater than or equal to the preset dew point temperature, the indoor fan is adjusted to run at a first rotating speed;
and when the indoor environment temperature is lower than the preset dew point temperature, the indoor fan is adjusted to switch between the second rotating speed and the third rotating speed.
