Example 1

Fig. 1 is a first flowchart illustrating a condensation preventing air conditioner control method 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, obtaining a first operation parameter of the air conditioner, wherein the first operation parameter at least comprises: the system comprises an inner fan rotating speed, 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, the inner fan of the air conditioner is driven to operate by 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, that is, 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 by obtaining the current operating data such as the working voltage and/or working current of the current operation of the inner fan;

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 rotation speed condition, a first humidity condition, a first inner coil temperature condition and a first time long 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 rotation speed, the temperature, the humidity, the operation duration and the like of the inner fan, so that the accuracy of judging 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 rotating speed condition, the rotating speed of the inner fan is a low wind rotating speed gear; here, for the existing type of air conditioner product, the rotation speed of the internal fan of the air conditioner is generally divided into a plurality of different gears, for example, one gear division manner is a low wind rotation speed gear, a medium wind rotation speed gear and a high wind rotation speed gear, each gear corresponds to a rotation speed value or a rotation speed range value, and as the gear is increased, the specific numerical value of the rotation speed value or the rotation speed range value is increased; the first rotating speed condition is based on judging whether the gear of the current inner fan rotating speed is in a low wind rotating speed gear, and if so, the first rotating speed condition is met; if not, the first rotating speed condition is not met;

here, the advantage of introducing the parameter of the rotation speed of the inner fan into the judgment of the dew condensation problem of the air conditioner is that when the air conditioner operates at a low rotation speed, the speed of the indoor air flowing through the indoor unit is low, and the time of staying in the indoor unit is long, so that the moisture in the indoor air can be condensed into dew on the indoor heat exchanger for a sufficient time. Therefore, in the case where the rotation speed of the internal fan is low, the air conditioner may cause a condensation problem.

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 38.4.

The air conditioner meets a first rotating speed condition, a first humidity condition and a first inner coil temperature condition, and the accumulated time of the air conditioner is longer than a first time;

in this embodiment, if the accumulated time period during which the air conditioner satisfies the first rotation speed condition, the first humidity condition and the first inner coil temperature condition is short, such as only maintaining for 1 minute, 2 minutes, etc., the actual condensation amount of the air conditioner is small and can be ignored. Under the condition of longer duration, the air conditioner is easy to generate condensation, so that the first condensation preventing condition also comprises a first duration condition so as to reduce the problems of misjudgment and the like caused by temperature and humidity fluctuation in a short time.

Optionally, the first time length is 1 hour;

and S103, controlling the air conditioner to execute a preset first anti-condensation operation in response to the fact that the air conditioner meets the 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.

Alternatively, for the air-conditioning product of the fixed-frequency type, since the operating frequency of the compressor cannot be adjusted, the first anti-condensation operation performed by the air conditioner in step S103 includes: and controlling and increasing the rotating speed of an inner fan of the air conditioner to a first set rotating speed.

Here, the first set rotation speed is a rotation speed higher than the low wind rotation speed gear, such as a medium wind rotation speed gear or a high wind rotation speed gear.

Or, based on the low wind rotation speed gear, increasing the rotation speed of the inner fan by a set rotation speed value, and if the rotation speed is increased by 30rpm, the rotation speed of the inner fan after adjustment is R +30, wherein R refers to the low wind rotation speed gear.

Fig. 2 is a schematic flow chart diagram of a condensation preventing air conditioner control method according to the embodiment (a).

In an optional embodiment, after the air conditioner executes the preset first condensation preventing operation, the actual operation parameters of the air conditioner are different from the operation parameters of the air conditioner during normal operation, so that the actual outlet air temperature and the like of the air conditioner can also change, and in order to shorten the occupied time of the first condensation preventing operation and enable the air conditioner to be restored to the initial operation state as soon as possible; the control method of the invention also comprises a step of judging and controlling the first anti-condensation operation to exit; specifically, as shown in fig. 2, another anti-condensation air conditioner control method according to the present invention includes:

s201, acquiring a first operation parameter of the air conditioner;

in this embodiment, the specific implementation process of step S201 may refer to step S101, which is not described herein again;

s202, determining whether the air conditioner meets a first anti-condensation condition or not based on the first operation parameter;

in this embodiment, the specific implementation process of step S202 may refer to step S102, which is not described herein again;

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;

in this embodiment, the specific implementation process of step S203 may refer to step S103, which is not described herein again;

s204, obtaining second operation parameters when the air conditioner executes the first anti-condensation operation, wherein the second operation parameters comprise one or more of 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 S204 may refer to step S101, which is not described herein again;

here, based on the specific type and number of the exit conditions in step S205, the type and number of the second operation parameters that need to be obtained in step S204 may be predetermined, and if the exit conditions only include the second humidity conditions, step S204 only obtains the single parameter of the second indoor humidity; or, if the exit condition only includes the second inner coil temperature condition, the three parameters of the second indoor temperature, the second indoor humidity and the second inner coil temperature need to be acquired respectively;

s205, determining whether the air conditioner meets an exit condition or not based on the second operation parameter, wherein the exit condition comprises one or more of the following conditions:

a second humidity condition, wherein the second indoor humidity is not greater than the first humidity threshold; here, when the second indoor humidity is not greater than the first indoor threshold, it indicates that the humidity in the indoor environment is low, the moisture content in the indoor air is low, the condensed dew of the indoor air flowing through the indoor unit in the indoor unit is also low, and the air conditioner is not prone to generate a condensation problem;

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 + the second indoor temperature + B + the second indoor humidity-C;

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 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, in step S102, if the air conditioner only satisfies the first rotation speed condition, but does not satisfy the first humidity condition and the first inner coil temperature condition, although the rotation speed of the inner fan of the air conditioner is low, the indoor unit is not easily condensed by the conditions such as the current indoor ambient humidity and the current inner coil temperature, and therefore the first consumption reduction operation is controlled to be executed, so as to reduce the energy consumption of the air conditioner operation through the first consumption reduction operation.

In an alternative embodiment, the first consumption reduction operation comprises: and controlling to reduce the rotating speed of an inner fan of the air conditioner to a second set rotating speed.

Here, the second set rotation speed is a rotation speed value lower than the current actual rotation speed in the low wind rotation speed wind gear, for example, the rotation speed range corresponding to the low wind rotation speed wind gear of one air conditioner type is 0-60rpm/min, when the air conditioner only meets the first rotation speed condition but does not meet the first humidity condition and the first inner coil temperature condition, the current actual rotation speed of the air conditioner is 50rpm/min, and the second set rotation speed is a rotation speed value lower than 50rpm/min, for example, 40rpm/min, 30rpm/min, and the like.

Fig. 3 is a first flowchart illustrating the condensation preventing air conditioner control method according to the second embodiment of the present invention.

As shown in fig. 3, the present invention provides still another condensation prevention air conditioner control method; specifically, the flow steps of the control method mainly include:

s301, obtaining a first operation parameter of the air conditioner, wherein the first operation parameter at least comprises: the system comprises an inner fan rotating speed, a first indoor temperature, a first indoor humidity and a first inner coil temperature;

the second inner coil temperature < A + B + C;

here, "a × first indoor temperature + B × first indoor humidity-C" used for the second inner coil temperature pricing coincides with step S302; when the temperature condition of the second inner coil is met, the current temperature of the inner coil indicates that dew is easy to condense in the indoor unit, and the condensation problem is not effectively improved by executing the first anti-condensation operation;

Optionally, after the air conditioner performs the preset first anti-condensation operation or the preset second anti-condensation operation, the actual operation parameters of the air conditioner are different from the operation parameters of the air conditioner during normal operation, so that the actual outlet air temperature and the like of the air conditioner can also change, and in order to shorten the occupied time of the anti-condensation operation and enable the air conditioner to be restored to the initial operation state as soon as possible; the control method of the invention also comprises a step of judging and controlling whether the first anti-condensation operation or the second anti-condensation operation is exited; the control method further comprises the following steps: acquiring a third operating parameter when the air conditioner executes a first condensation preventing operation or a second condensation preventing operation, wherein the third operating parameter comprises one or more of the following parameters: a second indoor temperature, a second indoor humidity, and a second inner coil temperature; determining whether the air conditioner meets an exit condition based on the third operating parameter, wherein the exit condition comprises one or more of the following conditions: a third humidity condition, wherein the humidity in the third chamber is not greater than the first humidity threshold; and under the condition of the temperature of the third inner coil, the temperature of the third inner coil meets the following relational expression: the temperature of the third inner coil is more than or equal to A plus the third indoor temperature plus B plus the third indoor humidity-C; and controlling the air conditioner to exit the current condensation preventing operation in response to the air conditioner meeting the exit condition.
