Embodiments may be referred to herein, individually or collectively, by the term "invention" merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed. Herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed. The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the structures, products and the like disclosed by the embodiments, the description is relatively simple because the structures, the products and the like correspond to the parts disclosed by the embodiments, and the relevant parts can be just described by referring to the method part.

The air conditioner is a common electric appliance in daily life, and can adjust the indoor temperature, namely, raise or lower the temperature, so that the indoor temperature is matched with the preset temperature of a user. However, when the indoor air humidity is relatively high, the temperature of the inner coil is lower than the current dew point temperature, and a large amount of condensation is generated at the moment, so that the air conditioner has a serious water blowing problem in the operation process, and the energy saving and the performance of the air conditioner are influenced.

Fig. 1 is a flowchart illustrating an air conditioner anti-condensation control method according to an exemplary embodiment. As shown in fig. 1, the process of the air conditioner anti-condensation control includes:

step 101: and acquiring the current temperature value and the current humidity value of the air conditioning action area, and determining the current dew point temperature value of the air conditioning action area.

In the embodiment of the invention, if the air conditioner is provided with the humidity sensor, the current humidity value can be directly obtained through the humidity sensor. If no humidity sensor is arranged, the current humidity value can be obtained according to the current temperature value, the temperature value of the coil pipe of the internal machine, the frequency value of the compressor and the like.

Therefore, the current temperature value of the air conditioner action area, the temperature value of the coil of the internal machine of the air conditioner and the frequency value of the compressor can be obtained, and then the current humidity value can be determined according to the obtained values, which can include: obtaining a current humidity value in the current temperature and humidity values through a formula (1) according to the current temperature value, the temperature value of an inner machine coil of the air conditioner and the running frequency value of a compressor; or, the opening value of the electronic expansion valve in the air conditioner is also obtained, and the current humidity value in the current temperature and humidity value is obtained through a formula (2) according to the current temperature value, the temperature value of the coil pipe of the internal machine, the running frequency value of the compressor and the opening value.

Rh＝A₂*T1+B₂*T2+C₂Hz + Df + F-formula (2)

Wherein Rh is the current humidity value, T1 is the current temperature value, T2 is the temperature value of the coil of the internal machine, hz is the frequency value of the compressor, f is the opening value, A₁、B₁、C₁、A₂、B₂、C₂D, E, F are constants determined according to the type of air conditioner.

For example: for type one air conditioner, after multiple debugging statistics, preferably, A₁A constant of 8 or more and 12 or less, B₁Is a constant of-12 or more and-8 or less, C₁Is a constant between-2 and-1, and E is a constant between-10 and 20, so that the current humidity value can be obtained from the formula (1).

When T1 is 25, T2 is 14, hz is 50, its corresponding a₁＝10，B₁＝-10，C₁The correction value E is 10, and the current humidity value Rh is 70% by formula (1).

Of course, for other types of air conditioners, a can be determined through multiple debugging statistics₁、B₁、C₁Preferred value range of E, or determining A₂、B₂、C₂D, F. The details are not necessarily given as an example.

Therefore, a humidity sensor is not required to be added, the current humidity value can be obtained only according to the temperature value of the coil pipe of the inner machine of the air conditioner, the running frequency value of the compressor and the like, the hardware requirement is reduced, the space of the air conditioner is saved, and the resources are further saved.

In the embodiment of the invention, the current dew point temperature value of the air conditioning action area needs to be determined. The current dew point temperature value of the air conditioning action area can be determined by obtaining the dry bulb temperature value and the wet bulb temperature value corresponding to the air conditioner. For example, the current dew point temperature value of the air conditioning action area is determined according to the dry bulb temperature value and the wet bulb temperature value through the psychrometric chart. Of course, other methods for determining the corresponding dew point temperature value based on the dry-bulb temperature value and the wet-bulb temperature value applied to weather or engineering can also be applied to the implementation of the present invention.

Step 102: and adjusting the working parameter value of at least one device with the condensation prevention function in the air conditioner according to the current temperature difference between the current temperature value and the current dew point temperature value and the current humidity value.

Here, the anti-condensation control may be performed according to a current temperature difference between the current temperature value and the current dew point temperature value, and the current humidity value, and specifically, an operating parameter value of at least one device having an anti-condensation function in the air conditioner may be adjusted.

The frequency of the compressor is a main parameter for adjusting the refrigerating capacity or latent heat of the air conditioner, and the adjustment of the frequency value of the compressor can quickly influence the condensation result, so that the compressor of the air conditioner has the condensation prevention function. The adjustment of the opening degree of the electronic expansion valve can also effectively adjust the throttling degree of the refrigeration system, when the opening degree value of the electronic expansion valve is reduced, the temperature of the coil pipe of the internal machine is reduced, and the condensation is easier to form, when the opening degree value of the electronic expansion valve is increased, the temperature of the coil pipe of the internal machine is increased, the condensation can be effectively inhibited, and therefore the electronic expansion valve of the air conditioner has the condensation prevention function. Similarly, the fan of the air conditioner can also adjust the refrigerating capacity or latent heat of the air conditioner, namely the fan of the air conditioner also has the condensation prevention function. Thus, performing anti-condensation control may include: and adjusting the working parameter value of at least one device with the condensation preventing function in the air conditioner. Wherein the device comprises: the corresponding working parameter values are respectively the frequency value of the compressor, the wind speed value of the fan and the opening value of the electronic expansion valve.

According to the current temperature difference between the current temperature value and the current dew point temperature value and the current humidity value, the working parameter value of at least one device with the condensation preventing function in the air conditioner is adjusted, so that the temperature difference range where the current temperature difference is located can be determined firstly, and then the humidity range where the current humidity value is located is determined, and therefore different adjustment strategies are adopted according to different temperature difference ranges and different humidity ranges. Or, the humidity range of the current humidity value is determined, the temperature difference range of the current temperature difference value is determined, and then different adjustment strategies are adopted for different temperature difference ranges and different humidity ranges.

Accordingly, adjusting an operating parameter value of at least one device having an anti-condensation function in an air conditioner may include: if the current temperature difference is larger than the first set temperature value, adjusting the current frequency value of a compressor with the condensation preventing function in the air conditioner according to the current humidity value; if the current temperature difference is larger than the second set temperature value and smaller than or equal to the first set temperature value, increasing the current opening value of an electronic expansion valve with the condensation prevention function in the air conditioner by the set opening value; and if the current temperature difference is greater than the third set temperature value and less than or equal to the second set temperature value, the current wind speed value of the fan with the condensation prevention function in the air conditioner is increased by the set wind speed gear value.

Wherein, according to the current humidity value, adjusting the current frequency value of the compressor having the anti-condensation function in the air conditioner may include: if the current humidity value is larger than the second set humidity value, the current frequency value of the compressor of the air conditioner is reduced by a first set proportion, and/or the current opening value of the electronic expansion valve of the air conditioner is increased by a set opening value, and/or the current wind speed value of the fan of the air conditioner is increased by a set wind speed gear value.

Alternatively, adjusting the operating parameter value of at least one device having the anti-condensation function in the air conditioner may include: if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the second set humidity value, reducing the current frequency value of a compressor with an anti-condensation function in the air conditioner by a first set proportion; and if the current temperature difference value is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, reducing the current frequency value of the compressor by a second set proportion.

Alternatively, adjusting the operating parameter value of at least one device having the anti-condensation function in the air conditioner may include: if the current temperature difference value is greater than a first set temperature value and the current humidity value is greater than the first set humidity value, reducing the current frequency value of a compressor with an anti-condensation function in the air conditioner by a first set proportion; if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the second set humidity value and less than or equal to the first set humidity value, reducing the current frequency value of the compressor by a first set proportion, or increasing the current opening value of an electronic expansion valve with an anti-condensation function in the air conditioner by a set opening value; and if the current temperature difference is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, increasing the current opening value of the electronic expansion valve by the set opening value.

The first set temperature value is greater than the second set temperature value, and the second set temperature value is greater than the third set temperature value. The first set humidity value is greater than the second set humidity value. And the first set proportion is greater than or equal to the second set proportion. For example: the first set temperature value is 5, the second set temperature value is 3, and the third temperature value is 0. Or the first set temperature value is 6, the second set temperature value is 4, and the third temperature value is 1. Or the first set temperature value is 5.5, the second set temperature value is 3.5, and the third temperature value is 0.5. Alternatively, the first set temperature value is 6.5, the second set temperature value is 3, the third temperature value is 0.5, and so on. The first set humidity value is 80%, and the second set humidity value is 70%; alternatively, the first set humidity value is 82% and the second set humidity value is 68%; alternatively, the first set humidity value is 85%, the second set humidity value is 75%, and so on. The first set proportion is 20%, and the second set proportion is 20%, 15% or 10%; alternatively, the first set ratio is 15%, the second set ratio is 15% or 10%, and so on.

When the current temperature difference value is larger than the first set temperature value, the air conditioner is easy to generate condensation, and the frequency value of the compressor of the air conditioner is adjusted by adjusting the main parameter of the refrigerating capacity or latent heat of the air conditioner, so that the generation of condensation can be quickly and effectively inhibited, and the condensation prevention control is quickly and effectively carried out.

The adjustment of the opening degree of the electronic expansion valve can also effectively adjust the throttling degree of the refrigeration system, when the opening degree value of the electronic expansion valve is reduced, the temperature of the coil pipe of the internal machine is reduced, and the condensation is easier to form, when the opening degree value of the electronic expansion valve is increased, the temperature of the coil pipe of the internal machine is increased, and the condensation can be effectively inhibited, so when the current temperature difference value is smaller than or equal to a first set temperature value, the condensation prevention control can be carried out by increasing the opening degree value of the electronic expansion valve.

And the wind speed of the fan of the air conditioner is increased, so that the air humidity can be reduced, and the condensation is effectively prevented. That is, when the current temperature difference is less than or equal to the first set temperature value, preferably, the current temperature difference is less than or equal to the second set temperature value, and the anti-condensation control can be performed by increasing the wind speed value of the fan.

Of course, the current temperature difference is greater than the first set temperature value, and the current humidity value is greater than the second set humidity value, and the condensation prevention control can also be performed by reducing the frequency value of the compressor. Alternatively, the frequency value of the compressor may be decreased, and the current opening value of the electronic expansion valve may be increased. Or, the frequency value of the compressor can be reduced, and the current wind speed value of the fan can be increased. Or, the frequency value of the compressor can be reduced, the current opening value of the electronic expansion valve can be increased, and the current wind speed value of the fan can be increased.

Or if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the second set humidity value, reducing the current frequency value of the compressor of the air conditioner. And if the current temperature difference value is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, the current frequency value of the compressor of the air conditioner is also reduced. And because the current temperature difference is greater than the first set temperature value and the current humidity value is greater than the second set humidity value, at the moment, the condensation speed is high and the risk of condensation is high, and therefore, the condensation prevention control can be continuously carried out by adjusting the current frequency value of the compressor. And if the obtained current humidity value is greater than the first set humidity value, the current frequency value of the compressor is continuously reduced.

Or if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the first set humidity value, reducing the current frequency value of the compressor; and if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the second set humidity value and less than or equal to the first set humidity value, reducing the current frequency value of the compressor, or increasing the current opening value of the electronic expansion valve, or increasing the current wind speed value of the fan. If the current temperature difference is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, rapid control is not needed, so that the current opening value of the electronic expansion valve can be increased, or the current wind speed value of the fan can be increased.

Of course, other strategies of combining one, two or three of reducing the frequency value of the compressor, increasing the opening value of the electronic expansion valve and increasing the wind speed value of the fan according to the current temperature difference between the current temperature value and the current dew point temperature value and the current humidity value may be applied to the anti-condensation control according to the embodiment of the present invention, which is not specifically listed.

Therefore, in the embodiment, the working parameter value of at least one device of the air conditioner can be adjusted according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the water blowing problem of the air conditioner is reduced, and the performance and the energy conservation of the air conditioner can be improved. In addition, the condensation prevention control is directly carried out in real time through software application without adjusting the hardware structure of the air conditioner, and the practicability and performance of the air conditioner are further improved.

In this embodiment, during the anti-condensation control process, the operating parameter value of at least one device of the air conditioner needs to be adjusted. For example: adjusting a current frequency value of the compressor; or adjusting the current frequency value of the compressor and/or the current opening value of the electronic expansion valve; or, adjusting the current frequency value of the compressor and/or the current wind speed value of the fan.

Fig. 2 is a flowchart illustrating an air conditioner anti-condensation control method according to an exemplary embodiment. As shown in fig. 2, the process of the air conditioner anti-condensation control includes:

step 201: and acquiring the current temperature value and the current humidity value of the air conditioning action area, and determining the current dew point temperature value of the air conditioning action area.

The specific implementation process here can be referred to as step 101. The current humidity value can be directly obtained through the humidity sensor. If no humidity sensor is arranged, the current humidity value can be obtained according to the current temperature value, the temperature value of the coil pipe of the internal machine, the frequency value of the compressor and the like. Similarly, the current dew point temperature value of the air conditioning action area can be determined by obtaining the dry bulb temperature value and the wet bulb temperature value in the air conditioner.

Step 202: and adjusting the current frequency value of a compressor with the condensation prevention function in the air conditioner according to the current temperature difference between the current temperature value and the current dew point temperature value and the current humidity value.

In this embodiment, if the current temperature difference is greater than the first set temperature value and the current humidity value is greater than the second set humidity value, the current frequency value of the compressor with the condensation prevention function in the air conditioner is reduced by the first set proportion. And if the current temperature difference value is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, reducing the current frequency value of the compressor with the condensation preventing function in the air conditioner by a second set proportion.

When the compressor is adjusting the temperature of the air conditioning action area, the frequency value of the compressor is generally higher, the temperature of the inner coil pipe is lower than the current dew point temperature, and at the moment, the condensation can be reduced relatively quickly by reducing the frequency value of the compressor. Of course, when the current temperature difference is greater than the first set temperature value, the condensation speed is fast and the risk of condensation is high, and therefore, the amplitude of reducing the frequency value of the compressor is large, for example: a reduction of 20%, or 25%, etc. When the current temperature difference is smaller than the first set temperature value, the condensation risk is higher, and the amplitude for reducing the frequency value of the compressor is relatively lower, for example: a 10%, or 5% reduction, etc.

Because the current temperature difference is greater than first settlement temperature value, and the current humidity value is greater than the second settlement humidity value, the current frequency value that only reduces once the compressor probably also has the condensation to produce, consequently, still need sample, continues to adjust the compressor frequency, after the current frequency that is about to have the compressor of preventing the condensation function in the air conditioner reduces first settlement proportion, still includes: when the set interval time is reached, acquiring the current humidity value of the air conditioning action area; and if the acquired current humidity value is larger than the first set humidity value, reducing the current frequency of the compressor by a first set proportion.

Therefore, in the embodiment, the frequency value of the compressor can be reduced according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the air conditioner that the water blowing problem occurs is reduced, and the performance of the air conditioner can be improved and the energy can be saved. In addition, the condensation prevention control is directly carried out in real time through software application without adjusting the hardware structure of the air conditioner, and the practicability and performance of the air conditioner are further improved.

Fig. 3 is a flowchart illustrating an air conditioner anti-condensation control method according to an exemplary embodiment. As shown in fig. 3, the process of the air conditioner anti-condensation control includes:

step 301: and acquiring the current temperature value and the current humidity value of the air conditioning action area, and determining the current dew point temperature value of the air conditioning action area.

Step 302: and adjusting the current frequency value of a compressor with an anti-condensation function or the current opening value of the electronic expansion valve in the air conditioner according to the current temperature difference between the current temperature value and the current dew point temperature value and the current humidity value.

If the current temperature difference value is greater than a first set temperature value and the current humidity value is greater than the first set humidity value, reducing the current frequency value of a compressor with an anti-condensation function in the air conditioner by a first set proportion; if the current temperature difference value is greater than the first set temperature value and the current humidity value is greater than the second set humidity value and less than or equal to the first set humidity value, reducing the current frequency value of the compressor by a first set proportion, or increasing the current opening value of an electronic expansion valve with an anti-condensation function in the air conditioner by a set opening value; and if the current temperature difference is less than or equal to the first set temperature value and the current humidity value is greater than the first set humidity value, increasing the current opening value of the electronic expansion valve by the set opening value.

Similarly, in order to further improve the anti-condensation effect, the current frequency of the compressor can be reduced by a first set proportion, sampling is carried out, and control is carried out, namely the current humidity value of the air conditioning action area is obtained when the set interval time is reached; and if the acquired current humidity value is larger than the first set humidity value, reducing the current frequency of the compressor by a first set proportion.

Therefore, in the embodiment, the frequency value of the compressor can be reduced or the opening value of the electronic expansion valve can be increased according to the temperature difference and the humidity between the temperature of the air conditioning action area and the dew point temperature, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the air conditioner that the water blowing problem occurs is reduced, and the performance of the air conditioner can be improved and the energy can be saved. In addition, the condensation prevention control is directly carried out in real time through software application without adjusting the hardware structure of the air conditioner, and the practicability and performance of the air conditioner are further improved.

In the first embodiment, the first step is,

fig. 4 is a flowchart illustrating an air conditioner anti-condensation control method according to an exemplary embodiment, where as shown in fig. 4, the air conditioner anti-condensation control process includes:

step 401: and acquiring the current temperature value Ts and the current humidity value of the air conditioning action area.

Step 402: and determining the current dew point temperature Tl of the air conditioning action area according to the dry bulb temperature and the wet bulb temperature.

Step 403: determine whether a current temperature difference (Ts-Tl) between the current temperature value and the current dew point temperature value is greater than a first set temperature value 5? If yes, go to step 404. Otherwise, step 406 is performed.

Step 404: is it determined whether the current humidity value is greater than the second set humidity value by 70%? If so, go to step 405, otherwise, the process ends.

(Ts-Tl) > 5 and the current humidity value > 70%, at which point the condensation speed is fast and there is a great risk of condensation, step 405 is performed. Otherwise, the flow ends.

Step 405: the current frequency of the compressor of the air conditioner is reduced by 20%.

Thus, the reduced compressor frequency value is 80% of the original frequency value. Of course, in order to further increase the anti-condensation effect, the current frequency of the compressor of the air conditioner may be reduced by 20%, and the current wind speed of the fan may be increased to the high wind speed gear value. Or, the current frequency of the compressor of the air conditioner is reduced by 20%, and the front opening value of the electronic expansion valve is increased by 50%. Or, the three are adjusted together, etc.

Step 406: determine (Ts-Tl) if greater than a second set temperature value 3? If so, go to step 407, otherwise, go to step 408.

Since 3 < (Ts-Tl) ≦ 5, the condensation rate is faster and step 407 may be performed.

Step 407: the current opening value of the electronic expansion valve is increased by 50.

Therefore, the condensation prevention control can be effectively carried out only by increasing the current opening value of the electronic expansion valve by 50, so that the frequency of the compressor is not influenced, and the refrigerating capacity of the air conditioner is not influenced.

Step 408: determine (Ts-Tl) if greater than a third set temperature value 0? If so, go to step 409, otherwise, the process ends.

Because 0 is less than (Ts-Tl) and less than or equal to 3, the working parameters of one device of the air conditioner are slightly adjusted.

Step 409: and (4) increasing the current wind speed value of the fan to a set wind speed gear value.

For example: the current wind speed value of the fan is adjusted from a low wind gear value to a high wind gear value, or the current wind speed value is adjusted from a high wind gear value to a strong wind gear value

Therefore, in the embodiment, the working parameter value of at least one device of the air conditioner can be adjusted according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the water blowing problem of the air conditioner is reduced, and the performance and the energy conservation of the air conditioner can be improved.

In the second embodiment, the first embodiment of the method,

fig. 5 is a flowchart illustrating an air conditioner condensation prevention control method according to a second exemplary embodiment, where as shown in fig. 5, the air conditioner condensation prevention control process includes:

step 501: and acquiring the current temperature value Ts and the current humidity value of the air conditioning action area.

Step 502: and determining the current dew point temperature Tl of the air conditioning action area according to the dry bulb temperature and the wet bulb temperature.

Step 503: determine (Ts-Tl) if greater than a first set temperature value 5? If yes, go to step 504. Otherwise, step 506 is performed.

Step 504: is it determined whether the current humidity value is greater than the second set humidity value by 70%? If so, go to step 505, otherwise, the process ends.

(Ts-Tl) > 5 and the current humidity value > 70%, at which point the condensation speed is fast and there is a great risk of condensation, step 505 is performed. Otherwise, the flow ends.

Step 505: the current frequency of the compressor of the air conditioner is reduced by 20%.

Step 506: is it determined whether the current humidity value is greater than the first set humidity value by 80%? If yes, go to step 507, otherwise, the process ends.

Although (Ts-Tl) ≦ 5, the current humidity value > 80%, there is also a risk of faster condensation, and thus, step 507 may be performed.

Step 507: the current frequency of the compressor of the air conditioner is reduced by 10%.

The condensation speed is only higher, so that the current frequency of the compressor does not need to be greatly reduced, the refrigerating capacity of the air conditioner is considered, and the temperature control effect of the air conditioner is further ensured. Of course, the present step is not limited thereto, and the current opening value of the electronic expansion valve of the air conditioner may be increased by 50. Alternatively, both adjustments are performed. Are not specifically listed.

Therefore, in the embodiment, the working parameter value of one device of the air conditioner can be adjusted according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, for example, the frequency value of the compressor is reduced, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the air conditioner that the water blowing problem occurs is reduced, and the performance and the energy conservation of the air conditioner can be improved.

Certainly, after the step 505, the current humidity value may be continuously sampled, and if the current humidity value of the air-conditioning action area is continuously obtained and is greater than 80% when the set interval time is reached, the current frequency of the compressor of the air conditioner may be continuously reduced by 20%. Thereby, the anti-condensation effect is further improved.

In the third embodiment, the first step is that,

fig. 6 is a flowchart illustrating an air conditioner anti-condensation control method according to a third exemplary embodiment, where as shown in fig. 6, the air conditioner anti-condensation control process includes:

step 601: and acquiring the current temperature value Ts and the current humidity value of the air conditioning action area.

Step 602: and determining the current dew point temperature Tl of the air conditioning action area according to the dry bulb temperature and the wet bulb temperature.

Step 603: determine (Ts-Tl) if greater than a first set temperature value 5? If yes, go to step 604. Otherwise, step 609 is performed.

Step 604: is it determined whether the current humidity value is greater than the second set humidity value by 70%? If so, go to step 605, otherwise, the process ends.

(Ts-Tl) > 5 and the current humidity value > 70%, at which point the condensation speed is fast and there is a great risk of condensation, step 605 is performed. Otherwise, the flow ends.

Step 605: the current frequency of the compressor of the air conditioner is reduced by 20%.

Step 606: determine whether the set interval time has been reached? If yes, go to step 607, otherwise, go back to step 606.

Step 607: is it determined whether the current humidity value is greater than the first set humidity value by 80%? If so, go to step 608, otherwise, the process ends.

Step 608: the current frequency of the compressor of the air conditioner is reduced by 20%.

Therefore, the current humidity value can be continuously adopted, the condensation prevention control is continuously carried out, and the condensation prevention effect is further improved.

Step 609: is it determined whether the current humidity value is greater than the first set humidity value by 80%? If so, go to step 610, otherwise, the process ends.

Although (Ts-Tl) ≦ 5, the current humidity value > 80%, there is also a risk of faster condensation, and thus, step 610 may be performed.

Step 610: the current opening value of the electronic expansion valve of the air conditioner is increased by 50.

The condensation speed is only higher, so the refrigeration capacity of the air conditioner can be considered, and only the parameter adjustment of the electronic expansion valve is needed. Of course, the present step is not limited thereto, and the current frequency of the compressor of the air conditioner may be reduced by 10%. Or the current wind speed value of the fan is increased, or two or three adjusting modes are executed. Are not specifically listed.

Therefore, in the embodiment, the operating parameter value of a device of the air conditioner can be adjusted according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, for example, the frequency value of the compressor is reduced or the opening value of the electronic expansion valve of the air conditioner is increased, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the water blowing problem of the air conditioner is reduced, and the performance and the energy conservation of the air conditioner can be further improved.

step 701: and acquiring the current temperature value Ts and the current humidity value of the air conditioning action area.

Step 702: and determining the current dew point temperature Tl of the air conditioning action area according to the dry bulb temperature and the wet bulb temperature.

Step 703: is it determined whether the current humidity value is greater than the first set humidity value by 80%? If so, only step 704 is required, otherwise, step 709 is performed.

Step 704: determine (Ts-Tl) if greater than a first set temperature value 5? If yes, go to step 705, otherwise, the process ends.

The current humidity value is > 80% and (Ts-Tl) > 5, at which point the condensation speed is fast and there is a great risk of condensation, and therefore step 705 is performed. Otherwise, the flow ends.

Step 705: the current frequency of the compressor of the air conditioner is reduced by 20%.

Step 706: determine whether the set interval time has been reached? If yes, go to step 707, otherwise, go back to step 706.

Step 707: is it determined whether the current humidity value is greater than the first set humidity value by 80%? If so, go to step 708, otherwise, the process ends.

Step 708: the current frequency of the compressor of the air conditioner is reduced by 20%.

Therefore, the current humidity value can be continuously adopted, the condensation prevention control is continuously carried out, and the condensation prevention effect is further improved. Of course, this step is also not the case, and the opening degree of the electronic expansion valve may be increased by 50. Or the current wind speed value of the fan is increased, or two or three adjusting modes are executed. Are not specifically listed.

Step 709: determine (Ts-Tl) if greater than a first set temperature value 5? If so, go to step 710, otherwise, the process ends.

Although the current humidity value is 80% or less, (Ts-Tl) > 5, there is also a risk of faster condensation, and thus, step 710 may be performed.

Step 710: the current opening value of the electronic expansion valve of the air conditioner is increased by 50.

Therefore, in the embodiment, the working parameter values of one or two devices of the air conditioner can be adjusted according to the temperature difference between the temperature of the air conditioning action area and the dew point temperature and the humidity, for example, the frequency value of the compressor is reduced, or the opening value of an electronic expansion valve of the air conditioner is increased, or the wind speed value of the fan is increased, so that the generation of a large amount of condensation can be reduced or prevented, the probability of the water blowing problem of the air conditioner is reduced, and the performance and the energy conservation of the air conditioner can be improved.
