Fig. 1 is a schematic flow chart illustrating a method for preventing condensation of an air conditioner according to an exemplary embodiment of the present invention.
As shown in fig. 1, the invention provides a method for preventing condensation of an air conditioner, which can be used for solving the problem that the air conditioner is easy to condense in environments of high temperature and high humidity in summer; specifically, the method mainly comprises the following steps:
s101, acquiring a first indoor humidity and a first indoor temperature of an environment where an air conditioner is located;
optionally, the air conditioner of the present invention is provided with one or more sensors, wherein the sensors include a humidity sensor, and the humidity sensor can be used for detecting the current humidity of the environment where the air conditioner is located; therefore, in step S101, a first indoor humidity of the environment where the air conditioner is located can be obtained by the humidity sensor;
similarly, the sensor of the air conditioner arrangement further comprises a temperature sensor operable to detect a first indoor temperature of an environment in which the air conditioner is located; thus, the first indoor temperature is obtained by the temperature sensor in step S101.
Here, the first indoor humidity and the first indoor temperature are respectively the current humidity and temperature of the indoor environment before the method for preventing condensation is started, and the humidity and temperature of the indoor environment directly affect whether condensation is generated in the air conditioner during operation and the amount of the condensation.
Before executing the anti-condensation control process of the present invention, the air conditioner generally operates according to a mode originally set by a user, for example, in a high-temperature and high-humidity condition in summer, the air conditioner generally is set by the user to operate a cooling mode, and therefore, in an optional application scenario of the present invention, step S101 is to detect the humidity and temperature conditions of the indoor environment through a humidity sensor during the operation of the air conditioner in the cooling mode.
S102, if the first indoor humidity and the first indoor temperature meet a preset first condensation condition, controlling an air conditioner to operate in a dehumidification mode;
optionally, the preset first condensation condition includes that a duration of the first indoor humidity being greater than a first humidity threshold (first humidity condition) and the first indoor temperature being greater than a temperature threshold (first temperature condition) is greater than or equal to a first duration;
the first humidity threshold is a preset threshold parameter, such as 70% or 75% of relative humidity. In this way, in step S102, in the case where the first indoor humidity is greater than the preset first humidity threshold, it may be determined that the first indoor humidity satisfies the first humidity condition among the preset condensation conditions, for example, the preset first humidity threshold is 70% of the relative humidity, and if the first indoor humidity detected at the time of performing step S101 once is 60% of the relative humidity, it may be determined that the first indoor humidity does not satisfy the first humidity condition among the preset condensation conditions; if the first indoor humidity detected when the step S101 is performed again is 80% of the relative humidity, it may be determined that the first indoor humidity satisfies a first humidity condition of a preset condensation condition.
Similarly, the first temperature threshold is also a preset threshold parameter, such as 22 ℃, 23 ℃, and the like. In this way, in step S102, in the case where the first indoor temperature is greater than the preset first temperature threshold, it may be determined that the first indoor temperature satisfies the first temperature condition among the preset condensation conditions, for example, the preset first temperature threshold is 22 ℃, and if the first indoor temperature detected at the time of performing step S101 once is 20 ℃, it may be determined that the first indoor temperature does not satisfy the first temperature condition among the preset condensation conditions; if the first indoor temperature detected when the step S101 is performed again is 25 ℃, it may be determined that the first indoor temperature satisfies a first temperature condition of a preset condensation condition.
Optionally, the first time period is 10 min.
Here, if the first indoor humidity and the first indoor temperature satisfy a preset first condensation condition, the air-conditioning operation dehumidification mode is controlled.
In the present embodiment, the dehumidification mode includes: controlling a compressor of the air conditioner to be switched to a first set frequency, performing first rotation speed compensation on an inner fan, switching an air deflector to a set air outlet angle, and continuously operating for a second time;
specifically, the first set frequency is a frequency value preset for the compressor, and optionally, the frequency value is a frequency value with a higher value so as to increase the exhaust temperature of the compressor, so that the temperature of a refrigerant flowing into the indoor unit heat exchanger after throttling can reach a lower temperature so as to improve the condensation and dehumidification effects; here, when the first indoor humidity and the first indoor temperature satisfy a preset first condensation condition, the air conditioner switches from a frequency corresponding to the previous operation mode to a first set frequency;
the first rotation speed compensation of the inner fan is a positive value or a negative value, when the first rotation speed compensation is the positive value, the rotation speed of the inner fan is increased, and when the first rotation speed compensation is the negative value, the rotation speed of the inner fan is reduced;
here, before the air conditioner leaves the factory, in the process of operating the air conditioner in the dehumidification mode at different coil temperatures (e.g., 1 ℃, 2 ℃, etc.) in step S102, the rate of moisture condensation on the outer surface of the heat exchanger of the indoor unit during the operation of the internal fan of the air conditioner at different rotation speeds is measured and calculated, and the rotation speed of the internal fan corresponding to the fastest rate of moisture condensation is associated with the coil temperature of the dehumidification mode, so that the association relationship between the coil temperature and the rotation speed of the internal fan during the operation of the dehumidification mode of one or more air conditioners can be obtained, and the association relationship is prestored in the air conditioner.
In this way, in the process of executing the dehumidification mode in step S102, the air conditioner may detect the coil temperature of the indoor unit through another sensor, and find and obtain the corresponding rotation speed of the inner fan according to the detected coil temperature and the preset association relationship. Therefore, the first rotation speed compensation is the difference value between the searched rotation speed and the rotation speed of the fan in the previous working mode of the air conditioner operation.
The air outlet angle of the air deflector can determine the air outlet volume of the air outlet of the air conditioner, the dehumidification capacity is different under different air volumes, and the purpose of improving the dehumidification capacity can be achieved by adjusting the air outlet angle of the air deflector.
Here, before the air conditioner leaves the factory, in the process of operating the air conditioner in the dehumidification mode at different coil temperatures (e.g., 1 ℃, 2 ℃, etc.) in step S102, the air deflector of the air conditioner operates at different air outlet angles and the rate of water vapor condensation on the outer surface of the indoor unit heat exchanger is measured, and the air outlet angle of the air deflector corresponding to the fastest rate of water vapor condensation is associated with the coil temperature in the dehumidification mode, so that the association relationship between the coil temperatures and the air outlet angles of the air deflectors when the one or more air conditioners operate in the dehumidification mode can be obtained, and the association relationship is prestored in the air conditioner.
In this way, in the process of executing the dehumidification mode in step S102, the air conditioner may detect the coil temperature of the indoor unit through another sensor, and find and obtain the corresponding air outlet angle of the air deflector according to the detected coil temperature and the preset association relationship.
Optionally, the second time period is 1 hour.
The air conditioner can increase condensed dew on the indoor unit of the air conditioner through the operation dehumidification mode, so that the phase state transformation and precipitation of water vapor in the indoor environment are accelerated, the water vapor content and the relative humidity in the air of the indoor environment can be reduced, the humidity condition of the indoor environment in the conventional mode (such as the refrigeration mode) of the air conditioner operation is changed, and then the condensation amount of the air conditioner is effectively reduced or even no condensation is generated in the conventional mode of the air conditioner operation.
And if the first indoor humidity and the first indoor temperature do not meet the preset first condensation condition, ending the control process.
S103, acquiring a second indoor humidity and a second indoor temperature after the air conditioner operates in the dehumidification mode;
in this embodiment, the specific implementation process of acquiring the second indoor humidity and the second indoor temperature in step S103 may refer to embodiment S101 in the foregoing, and is not described herein again.
S104, if the second indoor humidity and the second indoor temperature meet a preset second condensation condition, controlling the air conditioner to operate in an auxiliary dehumidification mode;
optionally, the preset second condensation condition includes that the second indoor humidity is greater than a second humidity threshold (second humidity condition), and a difference between the second indoor temperature and the target temperature is less than a set temperature difference threshold (second temperature condition);
the second humidity threshold is also a preset threshold parameter; here, the humidity threshold in the second condensation condition preset in step S104 is smaller than the humidity threshold in the condensation condition in step S102, and if the humidity threshold in the condensation condition in step S102 is 70% relative humidity, the humidity threshold in the condensation condition in step S104 is 60%, 50%, or the like relative humidity. In this way, in step S104, in the case where the second indoor humidity is greater than or equal to the preset humidity threshold, it may be determined that the second indoor humidity satisfies the preset second condensation condition, for example, the preset humidity threshold is 60% of the relative humidity, and if the detected second indoor humidity is 55% of the relative humidity when step S103 is performed once, it may be determined that the second indoor humidity does not satisfy the preset second condensation condition; if the detected second indoor humidity is 77% relative humidity when the step S103 is performed again, it may be determined that the second indoor humidity satisfies the preset second condensation condition.
Here, the humidity threshold in the second condensation condition preset in step S104 is set to be lower than the humidity threshold in the first condensation condition preset in step S102, so that the humidity range which can satisfy the second condensation condition in step S104 can be expanded, the auxiliary dehumidification mode can be triggered to be started, and the indoor humidity which causes the condensation problem when the air conditioner operates in the normal operation mode can be further reduced.
The target temperature is a temperature value or a temperature range to which the user desires to reach the indoor environment set by a device such as a remote controller or an input panel.
Optionally, the value of the temperature difference threshold is set to be 3 ℃.
Optionally, the auxiliary dehumidification mode includes: and controlling a compressor of the air conditioner to maintain the first set frequency, performing second rotation speed compensation on the internal fan and continuously operating for a third time.
The second rotation speed compensation of the inner fan is a positive value or a negative value, when the second rotation speed compensation is the positive value, the rotation speed of the inner fan is increased, and when the second rotation speed compensation is the negative value, the rotation speed of the inner fan is reduced;
here, before the air conditioner leaves the factory, in a manner of one or more sets of experimental measurements, etc., the humidity change rate and the temperature change rate in the test environment where the air conditioner is located in the process of operating the internal fan of the air conditioner at different rotation speeds are measured and calculated after the air conditioner operates in the dehumidification mode of step S102 in step S104, and the rotation speed of the internal fan corresponding to the maximum humidity drop and the minimum temperature change rate is used as the rotation speed of the internal fan in the auxiliary dehumidification mode, and the rotation speed of the internal fan is prestored in the air conditioner.
In this way, the air conditioner may switch the rotation speed of the inner fan to the previously stored rotation speed of the inner fan during the execution of the auxiliary dehumidification mode in step S104. Therefore, the dehumidification efficiency in the auxiliary dehumidification stage can be ensured, and the problems of fluctuation of indoor temperature and influence on the comfort level of users caused by the operation of the auxiliary dehumidification mode can be reduced.
Optionally, the third time period is 1 hour.
S105, acquiring a third indoor humidity after the auxiliary dehumidification mode of air conditioner operation;
here, the third indoor humidity in step S105 may be detected by the humidity sensor in the foregoing.
And S106, if the humidity in the third chamber meets a preset third condensation condition, controlling the air conditioner to operate in a condensation prevention mode.
Optionally, the third condensation condition preset in step S106 is the same as the first humidity condition in the first condensation condition in step S102, or the second humidity condition in the second condensation condition in step S104;
the anti-condensation air conditioner control method provided by the invention can accurately judge whether the current running state and the environmental condition of the air conditioner possibly cause the condensation problem of the air conditioner by judging through the parameters of indoor temperature and humidity and the like acquired for many times and combining the preset condensation condition, and can reduce the condensation problem of the air conditioner and improve the use experience of a user through the control flow combining the dehumidification mode, the auxiliary dehumidification mode and the anti-condensation mode.
In an optional embodiment, the control of the air conditioner operation condensation prevention mode specifically comprises the steps of controlling and adjusting one or more operation parameters of the air conditioner to enable the temperature of an inner coil of the air conditioner to be increased to a preset target coil temperature for reducing condensation of water vapor into dew; here, the target coil temperature is greater than the dew condensation temperature for the current operating conditions.
In this embodiment, the anti-condensation mode is to raise the temperature of the inner coil of the air conditioner to a temperature higher than the condensation temperature of the current working condition, so that the residual condensed water on the heat exchanger of the indoor unit is converted into a gaseous state, and the amount of the condensed water on the outer surface of the heat exchanger of the indoor unit is reduced. Here, since a large amount of moisture in the indoor ambient air has been condensed when the air conditioner operates the dehumidification mode in step S102, the moisture content of the indoor environment has been effectively reduced in step S102; after the air conditioner executes the integrated process, the air conditioner is switched to the previous working mode to operate (such as a refrigeration mode), and the temperature environment of water vapor condensation can be caused due to the lower temperature of the surface of the heat exchanger of the indoor unit during the operation of the refrigeration mode, so that the amount of condensed water on the surface of the heat exchanger of the indoor unit is increased. Aiming at the problem, when the condensation condition of the step S104 is met, the temperature of the inner coil is controlled to be increased, so that the residual water vapor of the air conditioner after the air conditioner operates in the dehumidification mode and the auxiliary dehumidification mode is evaporated, the residual condensed water on the outer surface of the heat exchanger of the indoor unit is reduced, and the water quantity on the outer surface of the heat exchanger of the indoor unit after the air conditioner is switched back to the refrigeration mode can be reduced.
Generally, in the air-conditioning operation dehumidification mode and the auxiliary dehumidification mode, the temperature of a coil of an indoor unit of an air conditioner is much lower than that in the air-conditioning operation refrigeration mode, and therefore, the temperature of an indoor environment is further reduced in the process of the air-conditioning operation dehumidification mode. In an alternative embodiment, in order to reduce the influence of the secondary temperature fluctuation on the indoor environment when the air conditioner operates in the anti-condensation mode, the target coil temperature should also satisfy the following relationship:
the third indoor temperature-the target coil temperature is less than or equal to A;
and A is a calculation threshold, and the third indoor temperature is the third indoor temperature obtained after the air conditioner runs in the auxiliary dehumidification mode.
Optionally, a is a predetermined fixed value, such as 5 ℃, i.e. the temperature difference between the room temperature and the target coil temperature after the increase is less than or equal to 5 ℃. Generally, the temperature of the target coil is lower than the indoor temperature, the temperature difference between the indoor temperature and the raised target coil temperature is maintained within 5 ℃, and the problems that the indoor temperature is further reduced and the body feeling comfort of a user is influenced under the condition that the temperature of the target coil is lower (the temperature difference between the indoor temperature and the raised target coil temperature is greater than 5 ℃) can be solved.
Alternatively, in yet another alternative embodiment, the calculated threshold A is a parameter determined based on the current operating conditions. Specifically, the control method further includes: and determining a calculation threshold A based on the coil temperature in the auxiliary dehumidification mode of the air conditioner operation and a preset incidence relation.
Here, before the air conditioner leaves the factory, after the air conditioner operates in the auxiliary dehumidification mode at different coil temperatures (e.g., 1 ℃, 2 ℃, etc.) in step S104 is measured and calculated in a manner of one or more sets of experimental measurements, and if the third condensation condition in step S106 is satisfied, after the air conditioner operates in the anti-condensation mode at different target coil temperatures, the amount of condensation water remaining on the outer surface of the heat exchanger of the indoor unit is calculated, and the target coil temperature corresponding to the minimum amount of condensation water remaining is associated with the coil temperature, so that the association relationship between the coil temperature in the auxiliary dehumidification mode and the target coil temperature in the anti-condensation mode of one or more air conditioners can be obtained, and the association relationship is prestored in the air conditioner.
In this way, during the auxiliary dehumidification mode in step S104, the air conditioner may detect the coil temperature of the indoor unit through another sensor, and in step S104, the calculation threshold a is found according to the detected coil temperature and the preset association relationship.
In an optional embodiment, in the preset correlation, the coil temperature in the auxiliary dehumidification mode of the air conditioner and the calculation threshold a are in a positive correlation, that is, the higher the coil temperature in the auxiliary dehumidification mode is, the smaller the reduction of the indoor environment temperature in the dehumidification process is, the larger the calculation threshold a may be set, at this time, because the auxiliary dehumidification mode has a lower influence on the indoor environment temperature, the target coil temperature setting value in the condensation prevention mode of the air conditioner may also be lower, so that the present invention may control the overall influence of the control flow combining the dehumidification mode, the auxiliary dehumidification mode, and the condensation prevention mode on the indoor environment temperature within a limited range.
On the contrary, the lower the coil temperature in the auxiliary dehumidification mode is, the smaller the calculation threshold a is set to, so that the target coil temperature setting value in the air conditioner performing the anti-condensation mode may also be higher and close to the indoor temperature to compensate for the reduced temperature of the indoor environment caused in the dehumidification mode, and prevent the indoor temperature from being reduced and deviating from the comfortable temperature range desired by the user.
In an alternative embodiment, controlling and adjusting one or more operating parameters of the air conditioner includes:
a compressor of the air conditioner operates at a low frequency; optionally, a plurality of working frequency values or frequency ranges may be preset in the compressor of the air conditioner from low to high, where the air conditioner is adjusted to a lower working frequency value or frequency range when the compressor of the air conditioner operates in the anti-condensation mode;
an inner fan of the air conditioner runs at a high wind gear; the air conditioner is characterized in that a plurality of wind speed gears are preset on an inner fan of the air conditioner, such as a low wind gear, a medium wind gear and a high wind gear, the rotating speeds of the fans at the three gears are sequentially increased, and the air output of an indoor unit of the air conditioner is sequentially increased;
an outer fan of the air conditioner runs at a low wind gear; the method is characterized in that a gear setting mode similar to that of an inner fan of the air conditioner is adopted, a plurality of wind speed gears are preset on an outer fan of the air conditioner, such as a low wind gear, a medium wind gear and a high wind gear, the rotating speeds of the fans at the three gears are sequentially increased, and the air output of an outdoor unit of the air conditioner is sequentially increased;
the throttling device of the air conditioner operates at a large opening flow rate; optionally, a plurality of opening values or opening ranges can be preset in the throttling device of the air conditioner from small to large, and here, when the air conditioner operates in the anti-condensation mode, the throttling device of the air conditioner is adjusted to be a larger opening value or opening range;
the air guide component of the indoor unit of the air conditioner is switched to a set air outlet angle; optionally, the air guide assembly of the air conditioner comprises an air deflector provided with an air outlet of the air conditioner, wherein an air outlet angle is set as an angle at which the air conditioner can perform air outlet at the maximum air outlet amount, and at this time, the wind blocking influence of the air guide assembly on the air outlet airflow flowing through the air outlet is the lowest, so that the air outlet airflow with evaporated steam can be discharged out of the indoor unit as soon as possible.

Fig. 12 is a flowchart illustrating a method of preventing condensation of an air conditioner according to the present invention, according to still another exemplary embodiment.
As shown in fig. 12, the present invention provides another method for preventing condensation of an air conditioner, which can be used to solve the problem that the air conditioner is prone to condensation in environments such as high temperature and high humidity in summer; specifically, the method mainly comprises the following steps:
s1201, acquiring a first indoor humidity and a first indoor temperature of an environment where an air conditioner is located;

Here, if the first indoor humidity and the first indoor temperature satisfy a preset first condensation condition, the air conditioner operation temperature and humidity dual control mode is controlled.
In this embodiment, the specific process of the air-conditioning operation temperature and humidity dual control mode may refer to the technical content disclosed in the embodiment corresponding to fig. 11, which is not described herein again.
And if the first indoor humidity and the first indoor temperature do not meet the preset first condensation condition, ending the control process.

And S1204, if the second indoor humidity meets a preset second condensation condition, controlling the air conditioner to operate in an anti-condensation mode.
In this embodiment, the specific execution process of step S1204 may refer to embodiment S106 in the foregoing, which is not described herein again.
The air conditioner condensation preventing method provided by the invention can accurately judge whether the current running state and the environmental condition of the air conditioner possibly cause the condensation problem of the air conditioner by combining the parameters of indoor temperature, humidity and the like acquired for many times and combining the preset condensation condition, and can reduce the condensation problem of the air conditioner and improve the use experience of a user by combining a temperature-humidity double control mode and a condensation preventing mode.
In an optional embodiment, the control of the air conditioner operation condensation prevention mode specifically comprises the steps of controlling and adjusting one or more operation parameters of the air conditioner to enable the temperature of an inner coil of the air conditioner to be increased to a preset target coil temperature for reducing condensation of water vapor into dew; here, the target coil temperature is greater than the dew condensation temperature for the current operating conditions.
In this embodiment, the anti-condensation mode is to raise the temperature of the inner coil of the air conditioner to a temperature higher than the condensation temperature of the current working condition, so that the residual condensed water on the heat exchanger of the indoor unit is converted into a gaseous state, and the amount of the condensed water on the outer surface of the heat exchanger of the indoor unit is reduced. Here, since part of the moisture in the indoor ambient air has been condensed out when the air-conditioning operation is in the temperature-humidity dual control mode in step S102, the moisture content in the indoor environment has been effectively reduced in step S102; after the air conditioner executes the integrated process, the air conditioner is switched to the previous working mode to operate (such as a refrigeration mode), and the temperature environment of water vapor condensation can be caused due to the lower temperature of the surface of the heat exchanger of the indoor unit during the operation of the refrigeration mode, so that the amount of condensed water on the surface of the heat exchanger of the indoor unit is increased. Aiming at the problem, when the second condensation condition of the step S104 is met, the temperature of the inner coil is controlled to be increased, so that the residual water vapor of the air conditioner after the air conditioner operates in the temperature and humidity double-control mode is evaporated, the residual condensed water on the outer surface of the heat exchanger of the indoor unit is reduced, and the water quantity on the outer surface of the heat exchanger of the indoor unit after the air conditioner is switched back to the cooling mode can be reduced.
Generally, when the air conditioner operates in the temperature and humidity dual control mode, the temperature of a coil pipe of an indoor unit of the air conditioner is low, and therefore, the temperature of the indoor environment is further reduced in the process of operating the temperature and humidity dual control mode of the air conditioner. In an alternative embodiment, in order to reduce the influence of the secondary temperature fluctuation on the indoor environment when the air conditioner operates in the anti-condensation mode, the target coil temperature should also satisfy the following relationship:
indoor temperature-target coil temperature is less than or equal to A;
and A is a calculation threshold, and the indoor temperature is the indoor temperature obtained after the air conditioner runs in the temperature and humidity double-control mode.
Optionally, a is a predetermined fixed value, such as 5 ℃, i.e. the temperature difference between the room temperature and the target coil temperature after the increase is less than or equal to 5 ℃. Generally, the temperature of the target coil is lower than the indoor temperature, the temperature difference between the indoor temperature and the raised target coil temperature is maintained within 5 ℃, and the problems that the indoor temperature is further reduced and the body feeling comfort of a user is influenced under the condition that the temperature of the target coil is lower (the temperature difference between the indoor temperature and the raised target coil temperature is greater than 5 ℃) can be solved.
Alternatively, in yet another alternative embodiment, the calculated threshold A is a parameter determined based on the current operating conditions. Specifically, the control method further includes: and determining a calculation threshold value A based on the coil temperature in the temperature and humidity double-control mode of air conditioner operation and a preset incidence relation.
Here, before the air conditioner leaves the factory, after the air conditioner operates the temperature and humidity double control mode at different coil temperatures (e.g., 1 ℃, 2 ℃, etc.) in step S102 is measured and calculated in a manner of one or more sets of experimental measurements, and if the second condensation condition in step S104 is satisfied, after the air conditioner operates the anti-condensation mode at different target coil temperatures, the amount of condensation water remaining on the outer surface of the heat exchanger of the indoor unit is calculated, and the target coil temperature corresponding to the minimum amount of condensation water remaining is associated with the coil temperature, so that the association relationship between the coil temperature in the temperature and humidity double control mode of operation of one or more air conditioners and the target coil temperature in the anti-condensation mode can be obtained, and the association relationship is prestored in the air conditioner.
In this way, during the execution of the temperature and humidity dual control mode in step S102, the air conditioner may detect the coil temperature of the indoor unit through another sensor, and in step S104, the calculation threshold a is found according to the detected coil temperature and the preset association relationship.
In an optional embodiment, in the preset association relationship, the corresponding relationship of positive correlation between the coil temperature when the air conditioner operates in the temperature and humidity dual control mode and the calculation threshold a is set, that is, the higher the coil temperature when the temperature and humidity dual control mode is, the smaller the reduction amount of the indoor environment temperature in the dehumidification process is, the larger the calculation threshold a may be set, at this time, because the temperature influence of the temperature and humidity dual control mode on the indoor environment is lower, the target coil temperature setting value when the air conditioner executes the condensation prevention mode may also be lower, so that the overall influence of the control flow combining the temperature and humidity dual control mode and the condensation prevention mode on the indoor environment temperature may also be controlled within a limited range.
On the contrary, the lower the coil temperature in the temperature and humidity dual control mode is, the smaller the calculation threshold a is set to, so that the target coil temperature setting value in the air conditioner performing the anti-condensation mode may also be higher and close to the indoor temperature, so as to compensate for the reduced temperature of the indoor environment caused in the temperature and humidity dual control mode, and avoid the indoor temperature from being reduced and deviating from the comfortable temperature range desired by the user.
In an alternative embodiment, controlling and adjusting one or more operating parameters of the air conditioner includes:
a compressor of the air conditioner operates at a low frequency; optionally, a plurality of working frequency values or frequency ranges may be preset in the compressor of the air conditioner from low to high, where the air conditioner is adjusted to a lower working frequency value or frequency range when the compressor of the air conditioner operates in the anti-condensation mode;
an inner fan of the air conditioner runs at a high wind gear; the air conditioner is characterized in that a plurality of wind speed gears are preset on an inner fan of the air conditioner, such as a low wind gear, a medium wind gear and a high wind gear, the rotating speeds of the fans at the three gears are sequentially increased, and the air output of an indoor unit of the air conditioner is sequentially increased;
an outer fan of the air conditioner runs at a low wind gear; the method is characterized in that a gear setting mode similar to that of an inner fan of the air conditioner is adopted, a plurality of wind speed gears are preset on an outer fan of the air conditioner, such as a low wind gear, a medium wind gear and a high wind gear, the rotating speeds of the fans at the three gears are sequentially increased, and the air output of an outdoor unit of the air conditioner is sequentially increased;
the throttling device of the air conditioner operates at a large opening flow rate; optionally, a plurality of opening values or opening ranges can be preset in the throttling device of the air conditioner from small to large, and here, when the air conditioner operates in the anti-condensation mode, the throttling device of the air conditioner is adjusted to be a larger opening value or opening range;
the air guide component of the indoor unit of the air conditioner is switched to a set air outlet angle; optionally, the air guide assembly of the air conditioner comprises an air deflector provided with an air outlet of the air conditioner, wherein an air outlet angle is set as an angle at which the air conditioner can perform air outlet at the maximum air outlet amount, and at this time, the wind blocking influence of the air guide assembly on the air outlet airflow flowing through the air outlet is the lowest, so that the air outlet airflow with evaporated steam can be discharged out of the indoor unit as soon as possible.
