Example 1
Fig. 1 is a flowchart illustrating a control method of an anti-condensation air conditioner according to an embodiment (a).
As shown in fig. 1, the present invention provides a control method of an anti-condensation air conditioner; specifically, the flow steps of the control method mainly include:
s101, acquiring a first operation parameter of the air conditioner;
optionally, the first operating parameter at least includes: a first current frequency of the compressor, a first indoor temperature, a first indoor humidity, and a first inner coil temperature;
in this embodiment, the first operating parameter may be detected by a plurality of different types of sensors, or may be directly or indirectly obtained from the operating data of the air conditioner itself;
for example, a compressor of the air conditioner is driven to operate by electric energy supplied by the air conditioner, and the actual operating frequency of the compressor is mainly affected by the current operating voltage and/or operating current of the compressor, that is, a parameter of the compressor frequency and the operating voltage and/or operating current of the compressor form a certain correlation relationship, so that the current operating frequency can be obtained by further combining the correlation relationship by obtaining operating data such as the current operating voltage and/or operating current of the compressor, and the correlation relationship is used as the first current frequency of the current process;
an indoor unit of the air conditioner is provided with a temperature sensor, the temperature sensor can be used for detecting the current temperature parameter of the indoor environment, and the current temperature parameter detected by the temperature sensor can be obtained in the step S101 and is used as the first indoor temperature;
similarly, the indoor unit of the air conditioner is provided with a humidity sensor, the humidity sensor can be used for detecting the current humidity parameter of the indoor environment, and the current humidity parameter detected by the humidity sensor can be obtained in the step S101 and is used as the first indoor humidity;
similarly, another temperature sensor is also arranged at the inner coil pipe of the indoor unit of the air conditioner, the temperature sensor can be used for detecting the current temperature parameter of the inner coil pipe, and the current temperature parameter detected by the temperature sensor can be obtained in the step S101 and is used as the temperature of the first inner coil pipe;
s102, determining whether the air conditioner meets a first anti-condensation condition or not based on the first operation parameter;
in the embodiment, the first anti-condensation condition is used for determining whether the condensation problem exists or is about to occur under the current operation condition of the air conditioner; when the air conditioner meets the first anti-condensation condition, judging that the air conditioner exists or is about to generate condensation; when the air conditioner does not meet the first anti-condensation condition, judging that the air conditioner does not exist or cannot generate condensation, and further determining the subsequent operation of the air conditioner based on the first operation parameter and the judgment of the first anti-condensation condition;
in this embodiment, the first anti-condensation condition at least includes a first frequency condition, a first humidity condition and a first inner coil temperature condition, that is, the condition judgment of whether the air conditioner has a condensation problem or will generate the condensation problem is a comprehensive judgment based on the conditions of the compressor frequency, the temperature, the humidity, the inner coil temperature and the like, so that the judgment accuracy of the condensation problem of the air conditioner can be improved, and the misjudgment problem caused by the abnormality of individual parameters can be avoided;
specifically, under the first frequency condition, the first current frequency is greater than the refrigerating rated frequency; here, for the existing type of air-conditioning products, the air-conditioner generally operates according to the rated frequency, but in some cases, due to the actual heat exchange quantity requirement of the air-conditioner, such as the severe working conditions of low refrigeration temperature, large indoor and outdoor temperature difference and the like set by a user under the refrigeration condition, in order to meet the heat exchange quantity required by the lower refrigeration temperature, the compressor may have an over-frequency operation working state, and at this time, the actual operation frequency of the air-conditioner is greater than the refrigeration rated frequency; it should be understood that, since the condensation problem generally occurs in air-conditioning products operating in hot summer climate, in the present embodiment, only the refrigeration rated frequency corresponding to the refrigeration mode is used as the reference threshold for determining the magnitude of the first current frequency of the compressor;
the advantage of introducing the frequency of the compressor as a parameter for judging the condensation problem of the air conditioner is that when the compressor of the air conditioner runs at a frequency higher than the rated refrigeration frequency, the quantity of refrigerant input into the indoor unit of the air conditioner is large, the temperature of the refrigerant is low, the evaporation capacity of the indoor unit is large, the internal temperature of the indoor unit is reduced, and water vapor in indoor air flowing through the indoor unit is easier to condense into dew in the indoor unit. Therefore, in the case where the frequency of the compressor is low, a problem of condensation of the air conditioner may be caused.
A first humidity condition, a first indoor humidity being greater than a first humidity threshold; the first humidity threshold is used for representing an indoor humidity condition, and the first indoor humidity generally takes a humidity value with a larger value, such as 80% of relative humidity, 90% of relative humidity, and the like; here, when the indoor humidity is greater than the first humidity threshold, it indicates that the indoor humidity in the current indoor environment is greater and the water vapor content is greater; when the indoor humidity is not greater than the first humidity threshold, it is indicated that the indoor humidity in the current indoor environment is low and the water vapor content is low.
Here, the greater the indoor humidity is, the more moisture is mixed in the indoor air, and the more moisture is easily condensed into dew when the indoor air passes through the indoor unit of the air conditioner; therefore, in the case where the indoor humidity is large, the air conditioner may cause a condensation problem.
The temperature condition of the first inner coil pipe is that the temperature of the first inner coil pipe meets the following relational expression:
the first inner coil temperature is less than A, the first indoor temperature is + B, the first indoor humidity is-C, wherein A, B is a calculation coefficient, and C is a calculation constant;
the lower the temperature of the inner coil pipe is, the more dew is condensed when water vapor flows through the indoor unit, the temperature limit that the inner coil pipe is easy to condense dew is represented by the 'A + first indoor temperature + B + first indoor humidity-C', and when the current temperature of the inner coil pipe is lower than the temperature limit, the low-temperature environment of the inner coil pipe is easy to condense the water vapor in the indoor air flowing through the inner coil pipe into dew; when the current temperature of the inner coil is not lower than the temperature limit, the amount of dew condensation caused by the low-temperature environment of the inner coil is less;
optionally, the value of the calculation coefficient a is 0.95, the value of the calculation coefficient B is 0.26, and the calculation coefficient of the calculation constant C is 28.4.
S103, controlling the air conditioner to execute a preset first anti-condensation operation in response to the fact that the air conditioner meets a first anti-condensation condition;
the anti-condensation air conditioner control method provided by the invention can accurately judge whether the current operation state and the environmental condition of the air conditioner possibly cause the condensation problem of the air conditioner or not by collecting various first operation parameters and combining the preset anti-condensation condition for judgment, and timely execute the preset anti-condensation operation so as to reduce the occurrence of the condensation problem of the air conditioner and improve the use experience of a user.
S104, obtaining second operation parameters when the air conditioner executes the first condensation preventing operation, wherein the second operation parameters comprise the following parameters: a second indoor temperature, a second indoor humidity, and a second inner coil temperature;
in this embodiment, the obtaining manner of the second operation parameter in step S104 may refer to step S101, which is not described herein again;
s105, determining whether the air conditioner meets an exit condition or not based on the second operation parameter, wherein the exit condition comprises the following steps:
the temperature condition of the second inner coil pipe is that the temperature of the second inner coil pipe meets the following relational expression:
the temperature of the second inner coil is more than or equal to A plus the second indoor temperature plus B plus the second indoor humidity-C plus 1;
here, when the second inner coil temperature condition is satisfied, it is explained that the temperature condition of the inner coil at this time is less likely to cause dew condensation thereon, and the amount of dew condensation generated by the air conditioner is small.
And S106, responding to the condition that the air conditioner meets the exit condition, and controlling the air conditioner to exit the first condensation preventing operation.
Here, after the air conditioner exits the first anti-condensation operation, it may be again switched to the operation state before the first anti-condensation operation is performed to continue the operation.
Optionally, for an air conditioner product of the inverter type, the first anti-condensation operation performed by the air conditioner in step S103 includes: and controlling a compressor of the air conditioner to perform variable frequency operation at a set period. Through carrying out frequency conversion operation to the compressor, the frequency that makes the compressor changes with undulant form to can further change the refrigerant temperature of input indoor set, carry out undulant adjustment to the temperature of indoor set, change the temperature environment that causes dew condensation easily, and then reach the purpose that reduces dew condensation.
Specifically, the frequency conversion operation performed by the compressor for controlling the air conditioner at each set period includes:
the first stage, control the compressor to lower the frequency from the first upper limit frequency to the refrigeration nominal frequency with the first frequency reduction rate; here, the first upper limit frequency is a frequency value preset for the purpose of frequency conversion condensation prevention of the air conditioner, and the frequency value is a value between the first current frequency and the rated refrigeration frequency, or the first upper limit frequency is set as the first current frequency;
the second stage, controlling the compressor to run at the refrigerating rated frequency for a second time; the air conditioner runs at a refrigerating rated frequency lower than the first current frequency, so that the temperature of the refrigerant input into the indoor unit in the second time period is lower than that of the refrigerant before the frequency conversion operation; the actual temperature in the indoor unit is increased, and the condensation amount is reduced; the same condensation reduction effect is also similar in the first and third stages.
A third stage of controlling the compressor to increase the frequency from the refrigeration rated frequency to a first upper limit frequency at a first frequency increasing rate;
and a fourth stage of controlling the compressor to run at the first upper limit frequency for a third time period. Here, the compressor of the air conditioner operates at the first current frequency mainly to meet the requirement of the current working condition; because the actual operating frequency of the air conditioner in the first stage, the second stage and the third stage is lower than the first current operating frequency, the actual heat exchange performance of the air conditioner in the three stages cannot meet the requirement of the current working condition, therefore, the control flow of the invention restores the frequency to the first upper limit frequency in the third stage and maintains the operation for a period of time at the frequency in the fourth stage so as to meet the heat exchange requirement of the current working condition.
The frequency of the compressor is changed in a fluctuating mode by carrying out frequency conversion operation on the compressor, so that the temperature of a refrigerant input into the indoor unit can be further changed, the temperature of the indoor unit is subjected to fluctuating adjustment, the temperature environment which is easy to cause dew condensation is changed, and the aim of reducing dew condensation is fulfilled; by the aid of the method, adverse effects on maintaining the current temperature and humidity of the indoor environment due to variable frequency changes of the compressor can be reduced.

s202, determining whether the air conditioner meets a first anti-condensation condition or not based on the first operation parameter;
in the embodiment, the first anti-condensation condition is used for determining whether the condensation problem exists or is about to occur under the current operation condition of the air conditioner; when the air conditioner meets the first anti-condensation condition, judging that the air conditioner exists or is about to generate condensation; when the air conditioner does not meet the first anti-condensation condition, judging that the air conditioner does not exist or cannot generate condensation, and further determining the subsequent operation of the air conditioner based on the first operation parameter and the judgment of the first anti-condensation condition;
in this embodiment, the first anti-condensation condition at least includes a first frequency condition, a first humidity condition and a first inner coil temperature condition, that is, the condition judgment of whether the air conditioner has a condensation problem or will generate the condensation problem is a comprehensive judgment based on the conditions of the compressor frequency, the temperature, the humidity, the inner coil temperature and the like, so that the judgment accuracy of the condensation problem of the air conditioner can be improved, and the misjudgment problem caused by the abnormality of individual parameters can be avoided;
specifically, under the first frequency condition, the first current frequency is greater than the refrigerating rated frequency; here, for the existing type of air-conditioning products, the air-conditioner generally operates according to the rated frequency, but in some cases, due to the actual heat exchange quantity requirement of the air-conditioner, such as the severe working conditions of low refrigeration temperature, large indoor and outdoor temperature difference and the like set by a user under the refrigeration condition, in order to meet the heat exchange quantity required by the lower refrigeration temperature, the compressor may have an over-frequency operation working state, and at this time, the actual operation frequency of the air-conditioner is greater than the refrigeration rated frequency; it should be understood that, since the condensation problem generally occurs in air-conditioning products operating in hot summer climate, in the present embodiment, only the refrigeration rated frequency corresponding to the refrigeration mode is used as the reference threshold for determining the magnitude of the first current frequency of the compressor;
the advantage of introducing the frequency of the compressor as a parameter for judging the condensation problem of the air conditioner is that when the compressor of the air conditioner runs at a frequency higher than the rated refrigeration frequency, the quantity of refrigerant input into the indoor unit of the air conditioner is large, the temperature of the refrigerant is low, the evaporation capacity of the indoor unit is large, the internal temperature of the indoor unit is reduced, and water vapor in indoor air flowing through the indoor unit is easier to condense into dew in the indoor unit. Therefore, in the case where the frequency of the compressor is low, a problem of condensation of the air conditioner may be caused.
A first humidity condition, a first indoor humidity being greater than a first humidity threshold; the first humidity threshold is used for representing an indoor humidity condition, and the first indoor humidity generally takes a humidity value with a larger value, such as 80% of relative humidity, 90% of relative humidity, and the like; here, when the indoor humidity is greater than the first humidity threshold, it indicates that the indoor humidity in the current indoor environment is greater and the water vapor content is greater; when the indoor humidity is not greater than the first humidity threshold, it is indicated that the indoor humidity in the current indoor environment is low and the water vapor content is low.
Here, the greater the indoor humidity is, the more moisture is mixed in the indoor air, and the more moisture is easily condensed into dew when the indoor air passes through the indoor unit of the air conditioner; therefore, in the case where the indoor humidity is large, the air conditioner may cause a condensation problem.
The temperature condition of the first inner coil pipe is that the temperature of the first inner coil pipe meets the following relational expression:
the first inner coil temperature is less than A, the first indoor temperature is + B, the first indoor humidity is-C, wherein A, B is a calculation coefficient, and C is a calculation constant;
the lower the temperature of the inner coil pipe is, the more dew is condensed when water vapor flows through the indoor unit, the temperature limit that the inner coil pipe is easy to condense dew is represented by the 'A + first indoor temperature + B + first indoor humidity-C', and when the current temperature of the inner coil pipe is lower than the temperature limit, the low-temperature environment of the inner coil pipe is easy to condense the water vapor in the indoor air flowing through the inner coil pipe into dew; when the current temperature of the inner coil is not lower than the temperature limit, the amount of dew condensation caused by the low-temperature environment of the inner coil is less;
optionally, the value of the calculation coefficient a is 0.95, the value of the calculation coefficient B is 0.26, and the calculation coefficient of the calculation constant C is 28.4.
S203, controlling the air conditioner to execute a preset first anti-condensation operation in response to the fact that the air conditioner meets a first anti-condensation condition;
the anti-condensation air conditioner control method provided by the invention can accurately judge whether the current operation state and the environmental condition of the air conditioner possibly cause the condensation problem of the air conditioner or not by collecting various first operation parameters and combining the preset anti-condensation condition for judgment, and timely execute the preset anti-condensation operation so as to reduce the occurrence of the condensation problem of the air conditioner and improve the use experience of a user.
S204, obtaining a second operation parameter when the air conditioner executes the first anti-condensation operation, wherein the second operation parameter comprises the following parameters: a second indoor humidity;
in this embodiment, in the step S204, the obtaining manner of the second operation parameter may refer to the step S201, which is not described herein again;
s205, determining whether the air conditioner meets an exit condition or not based on the second operation parameter, wherein the exit condition comprises:
a second humidity condition, wherein the second indoor humidity is less than a second humidity threshold;
here, when the second humidity condition is satisfied, it is explained that the indoor humidity condition at this time is less likely to cause dew condensation thereon, and the amount of dew condensation generated by the air conditioner is small.
Preferably, the second humidity threshold is smaller than the first humidity threshold, such as 90% relative humidity for the first humidity threshold and 80% relative humidity for the second humidity threshold. Here, the indoor humidity is greater than the operating mode humidity condition that first humidity threshold value is easy to produce the condensation, and indoor humidity is less than the operating mode humidity condition that second humidity threshold value is difficult to produce the condensation, and certain humidity difference value of interval between two humidity threshold values to the fluctuation of indoor humidity leaves certain space, reduces the erroneous judgement problem because of humidity fluctuation causes.
And S206, responding to the condition that the air conditioner meets the exit condition, and controlling the air conditioner to exit the first condensation preventing operation.
Here, after the air conditioner exits the first anti-condensation operation, it may be again switched to the operation state before the first anti-condensation operation is performed to continue the operation.
Optionally, for an air conditioner product of the inverter type, the first anti-condensation operation performed by the air conditioner in step S103 includes: and controlling a compressor of the air conditioner to perform variable frequency operation at a set period. Through carrying out frequency conversion operation to the compressor, the frequency that makes the compressor changes with undulant form to can further change the refrigerant temperature of input indoor set, carry out undulant adjustment to the temperature of indoor set, change the temperature environment that causes dew condensation easily, and then reach the purpose that reduces dew condensation.
Specifically, the frequency conversion operation performed by the compressor for controlling the air conditioner at each set period includes:
the first stage, control the compressor to lower the frequency from the first upper limit frequency to the refrigeration nominal frequency with the first frequency reduction rate; here, the first upper limit frequency is a frequency value preset for the purpose of frequency conversion condensation prevention of the air conditioner, and the frequency value is a value between the first current frequency and the rated refrigeration frequency, or the first upper limit frequency is set as the first current frequency;
the second stage, controlling the compressor to run at the refrigerating rated frequency for a second time; the air conditioner runs at a refrigerating rated frequency lower than the first current frequency, so that the temperature of the refrigerant input into the indoor unit in the second time period is lower than that of the refrigerant before the frequency conversion operation; the actual temperature in the indoor unit is increased, and the condensation amount is reduced; the same condensation reduction effect is also similar in the first and third stages.
A third stage of controlling the compressor to increase the frequency from the refrigeration rated frequency to a first upper limit frequency at a first frequency increasing rate;
and a fourth stage of controlling the compressor to run at the first upper limit frequency for a third time period. Here, the compressor of the air conditioner operates at the first current frequency mainly to meet the requirement of the current working condition; because the actual operating frequency of the air conditioner in the first stage, the second stage and the third stage is lower than the first current operating frequency, the actual heat exchange performance of the air conditioner in the three stages cannot meet the requirement of the current working condition, therefore, the control flow of the invention restores the frequency to the first upper limit frequency in the third stage and maintains the operation for a period of time at the frequency in the fourth stage so as to meet the heat exchange requirement of the current working condition.
The frequency of the compressor is changed in a fluctuating mode by carrying out frequency conversion operation on the compressor, so that the temperature of a refrigerant input into the indoor unit can be further changed, the temperature of the indoor unit is subjected to fluctuating adjustment, the temperature environment which is easy to cause dew condensation is changed, and the aim of reducing dew condensation is fulfilled; by the aid of the method, adverse effects on maintaining the current temperature and humidity of the indoor environment due to variable frequency changes of the compressor can be reduced.

Here, the greater the indoor humidity is, the more moisture is mixed in the indoor air, and the more moisture is easily condensed into dew when the indoor air passes through the indoor unit of the air conditioner; therefore, in the case where the indoor humidity is large, the air conditioner may cause a condensation problem.

Example (five)
Fig. 6 is a flowchart illustrating the anti-condensation air conditioner control method according to the embodiment (v).
As shown in fig. 6, the present invention provides a control method of an anti-condensation air conditioner; specifically, the flow steps of the control method mainly include:
s601, acquiring a first operation parameter of the air conditioner;
optionally, the first operating parameter at least includes: a first current frequency of the compressor, a first inner fan rotation speed, a first indoor temperature and a first inner coil temperature;
in this embodiment, the first operating parameter may be detected by a plurality of different types of sensors, or may be directly or indirectly obtained from the operating data of the air conditioner itself;
for example, a compressor of the air conditioner is driven to operate by electric energy supplied by the air conditioner, and the actual operating frequency of the compressor is mainly affected by the current operating voltage and/or operating current of the compressor, that is, a parameter of the compressor frequency and the operating voltage and/or operating current of the compressor form a certain correlation relationship, so that the current operating frequency can be obtained by further combining the correlation relationship by obtaining operating data such as the current operating voltage and/or operating current of the compressor, and the correlation relationship is used as the first current frequency of the current process;
similarly, the inner fan of the air conditioner is driven to operate by the electric energy supplied by the air conditioner, and the actual rotating speed of the inner fan is mainly influenced by the current working voltage and/or working current of the inner fan, namely, the parameter of the rotating speed of the inner fan and the working voltage and/or working current of the inner fan form a certain incidence relation, so that the current rotating speed of the inner fan can be obtained by further combining the incidence relation through obtaining the current operating data such as the working voltage and/or working current and the like of the current operation of the inner fan to serve as the rotating speed of the first inner fan;
the indoor unit of the air conditioner is provided with a temperature sensor, the temperature sensor can be used for detecting the current temperature parameter of the indoor environment, and the current temperature parameter detected by the temperature sensor can be obtained in the step S601 and is used as the first indoor temperature;
similarly, the indoor unit of the air conditioner is further provided with another temperature sensor at the inner coil, the temperature sensor can be used for detecting the current temperature parameter of the inner coil, and the current temperature parameter detected by the temperature sensor can be obtained in the step S601 and used as the temperature of the first inner coil;
s602, determining whether the air conditioner meets a first anti-condensation condition or not based on the first operation parameter;
in the embodiment, the first anti-condensation condition is used for determining whether the condensation problem exists or is about to occur under the current operation condition of the air conditioner; when the air conditioner meets the first anti-condensation condition, judging that the air conditioner exists or is about to generate condensation; when the air conditioner does not meet the first anti-condensation condition, judging that the air conditioner does not exist or cannot generate condensation, and further determining the subsequent operation of the air conditioner based on the first operation parameter and the judgment of the first anti-condensation condition;
in this embodiment, the first anti-condensation condition at least includes a first frequency condition and a first inner coil temperature condition, that is, the condition judgment of whether the air conditioner has a condensation problem or will generate the condensation problem of the invention is a comprehensive judgment based on the conditions of the compressor frequency, the temperature, the humidity, the inner coil temperature and the like, so that the judgment accuracy of the condensation problem of the air conditioner can be improved, and the misjudgment problem caused by the abnormality of individual parameters can be avoided;
specifically, under the first frequency condition, the first current frequency is greater than the refrigerating rated frequency; here, for the existing type of air-conditioning products, the air-conditioner generally operates according to the rated frequency, but in some cases, due to the actual heat exchange quantity requirement of the air-conditioner, such as the severe working conditions of low refrigeration temperature, large indoor and outdoor temperature difference and the like set by a user under the refrigeration condition, in order to meet the heat exchange quantity required by the lower refrigeration temperature, the compressor may have an over-frequency operation working state, and at this time, the actual operation frequency of the air-conditioner is greater than the refrigeration rated frequency; it should be understood that, since the condensation problem generally occurs in air-conditioning products operating in hot summer climate, in the present embodiment, only the refrigeration rated frequency corresponding to the refrigeration mode is used as the reference threshold for determining the magnitude of the first current frequency of the compressor;
the advantage of introducing the frequency of the compressor as a parameter for judging the condensation problem of the air conditioner is that when the compressor of the air conditioner runs at a frequency higher than the rated refrigeration frequency, the quantity of refrigerant input into the indoor unit of the air conditioner is large, the temperature of the refrigerant is low, the evaporation capacity of the indoor unit is large, the internal temperature of the indoor unit is reduced, and water vapor in indoor air flowing through the indoor unit is easier to condense into dew in the indoor unit.

the first inner coil temperature is larger than the first indoor temperature- (a is the first current frequency + b is the first inner fan rotating speed + c), wherein a and b are calculation coefficients, and c is a calculation constant;
optionally, the value of the calculation coefficient a is 0.095, the value of the calculation coefficient b is 0.026, and the value of the calculation constant c is-2.84.

Example (six)
Fig. 7 is a flowchart illustrating the anti-condensation air conditioner control method according to the sixth embodiment of the present invention.
As shown in fig. 7, the present invention provides a control method of an anti-condensation air conditioner; specifically, the flow steps of the control method mainly include:
s701, acquiring a first operation parameter of the air conditioner;
optionally, the first operating parameter at least includes: a first current frequency of the compressor, a first inner fan rotation speed, a first indoor temperature and a first inner coil temperature;
in this embodiment, the first operating parameter may be detected by a plurality of different types of sensors, or may be directly or indirectly obtained from the operating data of the air conditioner itself;
for example, a compressor of the air conditioner is driven to operate by electric energy supplied by the air conditioner, and the actual operating frequency of the compressor is mainly affected by the current operating voltage and/or operating current of the compressor, that is, a parameter of the compressor frequency and the operating voltage and/or operating current of the compressor form a certain correlation relationship, so that the current operating frequency can be obtained by further combining the correlation relationship by obtaining operating data such as the current operating voltage and/or operating current of the compressor, and the correlation relationship is used as the first current frequency of the current process;
similarly, the inner fan of the air conditioner is driven to operate by the electric energy supplied by the air conditioner, and the actual rotating speed of the inner fan is mainly influenced by the current working voltage and/or working current of the inner fan, namely, the parameter of the rotating speed of the inner fan and the working voltage and/or working current of the inner fan form a certain incidence relation, so that the current rotating speed of the inner fan can be obtained by further combining the incidence relation through obtaining the current operating data such as the working voltage and/or working current and the like of the current operation of the inner fan to serve as the rotating speed of the first inner fan;
the indoor unit of the air conditioner is provided with a temperature sensor, the temperature sensor can be used for detecting the current temperature parameter of the indoor environment, and the current temperature parameter detected by the temperature sensor can be obtained in the step S701 and is used as the first indoor temperature;
similarly, the indoor unit of the air conditioner is also provided with another temperature sensor at the inner coil, the temperature sensor can be used for detecting the current temperature parameter of the inner coil, and the current temperature parameter detected by the temperature sensor can be obtained in the step S701 and is used as the temperature of the first inner coil;
s702, determining whether the air conditioner meets a first anti-condensation condition or not based on the first operation parameter;
in the embodiment, the first anti-condensation condition is used for determining whether the condensation problem exists or is about to occur under the current operation condition of the air conditioner; when the air conditioner meets the first anti-condensation condition, judging that the air conditioner exists or is about to generate condensation; when the air conditioner does not meet the first anti-condensation condition, judging that the air conditioner does not exist or cannot generate condensation, and further determining the subsequent operation of the air conditioner based on the first operation parameter and the judgment of the first anti-condensation condition;
in this embodiment, the first anti-condensation condition at least includes a first frequency condition and a first inner coil temperature condition, that is, the condition judgment of whether the air conditioner has a condensation problem or will generate the condensation problem of the invention is a comprehensive judgment based on the conditions of the compressor frequency, the temperature, the humidity, the inner coil temperature and the like, so that the judgment accuracy of the condensation problem of the air conditioner can be improved, and the misjudgment problem caused by the abnormality of individual parameters can be avoided;
specifically, under the first frequency condition, the first current frequency is greater than the refrigerating rated frequency; here, for the existing type of air-conditioning products, the air-conditioner generally operates according to the rated frequency, but in some cases, due to the actual heat exchange quantity requirement of the air-conditioner, such as the severe working conditions of low refrigeration temperature, large indoor and outdoor temperature difference and the like set by a user under the refrigeration condition, in order to meet the heat exchange quantity required by the lower refrigeration temperature, the compressor may have an over-frequency operation working state, and at this time, the actual operation frequency of the air-conditioner is greater than the refrigeration rated frequency; it should be understood that, since the condensation problem generally occurs in air-conditioning products operating in hot summer climate, in the present embodiment, only the refrigeration rated frequency corresponding to the refrigeration mode is used as the reference threshold for determining the magnitude of the first current frequency of the compressor;
the advantage of introducing the frequency of the compressor as a parameter for judging the condensation problem of the air conditioner is that when the compressor of the air conditioner runs at a frequency higher than the rated refrigeration frequency, the quantity of refrigerant input into the indoor unit of the air conditioner is large, the temperature of the refrigerant is low, the evaporation capacity of the indoor unit is large, the internal temperature of the indoor unit is reduced, and water vapor in indoor air flowing through the indoor unit is easier to condense into dew in the indoor unit. Therefore, in the case where the frequency of the compressor is low, a problem of condensation of the air conditioner may be caused.
The temperature condition of the first inner coil pipe is that the temperature of the first inner coil pipe meets the following relational expression:
the first inner coil temperature is larger than the first indoor temperature- (a is the first current frequency + b is the first inner fan rotating speed + c), wherein a and b are calculation coefficients, and c is a calculation constant;
optionally, the value of the calculation coefficient a is 0.095, the value of the calculation coefficient b is 0.026, and the value of the calculation constant c is-2.84.

in this embodiment, the manner of obtaining the second operation parameter in step 704 refers to step S701, which is not described herein again.

the temperature condition of the second inner coil pipe is that the temperature of the second inner coil pipe meets the following relational expression:
the temperature of the second inner coil is more than or equal to A plus the second indoor temperature plus B plus the second indoor humidity-C plus 1;
optionally, the value of the calculation coefficient a is 0.95, the value of the calculation coefficient B is 0.26, and the value of the calculation constant C is 28.4.
And S706, responding to the condition that the air conditioner meets the exit condition, and controlling the air conditioner to exit the first condensation preventing operation.
Here, after the air conditioner exits the first anti-condensation operation, it may be again switched to the operation state before the first anti-condensation operation is performed to continue the operation.
Optionally, for an air conditioner product of the inverter type, the first anti-condensation operation performed by the air conditioner in step S703 includes: and controlling a compressor of the air conditioner to perform variable frequency operation at a set period. Through carrying out frequency conversion operation to the compressor, the frequency that makes the compressor changes with undulant form to can further change the refrigerant temperature of input indoor set, carry out undulant adjustment to the temperature of indoor set, change the temperature environment that causes dew condensation easily, and then reach the purpose that reduces dew condensation.
Specifically, the frequency conversion operation performed by the compressor for controlling the air conditioner at each set period includes:
the first stage, control the compressor to lower the frequency from the first upper limit frequency to the refrigeration nominal frequency with the first frequency reduction rate; here, the first upper limit frequency is a frequency value preset for the purpose of frequency conversion condensation prevention of the air conditioner, and the frequency value is a value between the first current frequency and the rated refrigeration frequency, or the first upper limit frequency is set as the first current frequency;
the second stage, controlling the compressor to run at the refrigerating rated frequency for a second time; the air conditioner runs at a refrigerating rated frequency lower than the first current frequency, so that the temperature of the refrigerant input into the indoor unit in the second time period is lower than that of the refrigerant before the frequency conversion operation; the actual temperature in the indoor unit is increased, and the condensation amount is reduced; the same condensation reduction effect is also similar in the first and third stages.
A third stage of controlling the compressor to increase the frequency from the refrigeration rated frequency to a first upper limit frequency at a first frequency increasing rate;
and a fourth stage of controlling the compressor to run at the first upper limit frequency for a third time period. Here, the compressor of the air conditioner operates at the first current frequency mainly to meet the requirement of the current working condition; because the actual operating frequency of the air conditioner in the first stage, the second stage and the third stage is lower than the first current operating frequency, the actual heat exchange performance of the air conditioner in the three stages cannot meet the requirement of the current working condition, therefore, the control flow of the invention restores the frequency to the first upper limit frequency in the third stage and maintains the operation for a period of time at the frequency in the fourth stage so as to meet the heat exchange requirement of the current working condition.
The frequency of the compressor is changed in a fluctuating mode by carrying out frequency conversion operation on the compressor, so that the temperature of a refrigerant input into the indoor unit can be further changed, the temperature of the indoor unit is subjected to fluctuating adjustment, the temperature environment which is easy to cause dew condensation is changed, and the aim of reducing dew condensation is fulfilled; by the aid of the method, adverse effects on maintaining the current temperature and humidity of the indoor environment due to variable frequency changes of the compressor can be reduced.
