The technical scheme provided by the application can be applied to a self-cleaning scene of air conditioning equipment, and in order to enable a person skilled in the art to better understand the application, a self-cleaning process of the air conditioning equipment is briefly described below.

In the operation process of the air conditioning equipment, for example, in a refrigeration mode, a compressor compresses a low-temperature low-pressure gaseous refrigerant to obtain a high-temperature high-pressure gaseous refrigerant, then the high-temperature high-pressure gaseous refrigerant flows into a condenser through a four-way valve to obtain a medium-temperature high-pressure liquid refrigerant, and the medium-temperature high-pressure liquid refrigerant passes through a plate heat exchanger to obtain a low-temperature high-pressure liquid refrigerant. Further, the low-temperature and high-pressure liquid refrigerant passes through the valve body of the evaporator in an open state, flows into the evaporator in the heat exchanger after the low-temperature and low-pressure liquid refrigerant is obtained, and evaporates into the low-temperature and low-pressure gaseous refrigerant after absorbing the heat of the air in the evaporator, and the air is absorbed with heat and temperature is reduced, so that the cooling effect is achieved.

After the air conditioning equipment is used for a long time, impurities may adhere to the heat exchanger of the air conditioning indoor unit, so that the heat exchanger is blocked, and the working performance of the air conditioner is affected. Based on this, it is necessary to clean the heat exchanger of the air conditioning apparatus, such as the indoor unit, according to the condition of the air conditioning apparatus. In the process of cleaning the heat exchanger of the indoor unit, the first choice needs to generate condensate water on the heat exchanger of the indoor unit, then the temperature is reduced to enable the condensate water to be condensed, impurities are condensed in ice cubes, and finally the ice cubes are heated to enable the ice cubes to fall off, so that the impurities attached to the heat exchanger are cleaned.

The application provides an air conditioner control scheme which mainly relates to a condensate water condensation link in a self-cleaning mode of air conditioning equipment.

The implementation details of the technical solutions of the embodiments of the present application are described in detail below:

referring to fig. 1, a flowchart of an air conditioner control method in an embodiment of the present application, which may be performed by a device having a calculation processing function, is shown. Referring to fig. 1, the air conditioner control method at least includes steps 110 to 150, and is described in detail as follows:

in step 110, in response to the activation of the self-cleaning mode of the air conditioner, a control program for controlling the air conditioner to liquefy air into condensed water at the indoor unit heat exchanger surface is triggered to be executed.

In the application, after the user actively triggers the self-cleaning mode of the air conditioner or the air conditioner automatically triggers the self-cleaning mode of the air conditioner according to the set triggering condition, a control program for controlling the air conditioner to liquefy the air into condensed water on the surface of the heat exchanger of the indoor unit is started to be executed.

In an embodiment of the application, when the air conditioning apparatus is operated in the self-cleaning mode, the air supply guide vane angle of the indoor unit can be adjusted, so that condensed water is more easily generated by the indoor unit, then the indoor environment temperature is detected through the temperature sensor, the indoor relative humidity H is detected through the humidity sensor, and the dew point temperature A of the indoor side is calculated according to the indoor environment temperature and the indoor relative humidity H for use in a subsequent control process.

The dew point temperature is the temperature at which the air is cooled to saturation under the condition that the water vapor content in the air is unchanged and the air pressure is kept constant.

With continued reference to FIG. 1, in step 130, in the control routine, an indoor unit fan gear is adjusted based on the indoor relative humidity, the indoor unit fan gear being positively correlated to the indoor relative humidity; and/or adjusting a compressor frequency according to a temperature in the indoor unit evaporator tube, the compressor frequency being positively correlated to the temperature in the indoor unit evaporator tube; and/or adjusting the frequency of the outdoor unit fan according to the temperature in the outdoor unit condenser tube, wherein the frequency of the outdoor unit fan is positively correlated with the temperature in the outdoor unit condenser tube.

In the present application, in the control program, several steps of adjusting the fan gear of the indoor unit, adjusting the frequency of the compressor, and adjusting the frequency of the fan of the outdoor unit may be performed entirely or partially. In addition, in the execution sequence, the operation may be performed in the sequence of adjusting the fan gear of the indoor unit, adjusting the frequency of the compressor, and adjusting the frequency of the fan of the outdoor unit, or in the sequence of adjusting the frequency of the compressor, adjusting the frequency of the fan of the outdoor unit, and adjusting the fan gear of the indoor unit, which is not specifically limited in this application.

Next, the present application will describe in detail the step 130 shown in fig. 1 by several embodiments.

In one embodiment of the present application, the adjustment of the fan gear of the indoor unit according to the indoor relative humidity may be performed according to the following several conditions:

first, if the indoor relative humidity is greater than or equal to the first set humidity, the indoor unit fan gear is adjusted to the first gear.

Second, if the indoor relative humidity is smaller than the first set humidity and larger than the second set humidity, the fan gear of the indoor unit is adjusted to a second gear, wherein the first gear is higher than the second gear.

Third, if the indoor relative humidity is less than or equal to the second set humidity, the fan gear of the indoor unit is adjusted to a third gear, wherein the third gear is lower than the second gear.

In this application, the first set humidity may be set to 70% to 90%.

According to the positive correlation between the fan gear of the indoor unit and the indoor relative humidity, the efficiency of forming condensed water in the indoor unit can be improved according to the positive correlation between the fan gear of the indoor unit and the indoor relative humidity, for example, when the indoor relative humidity is lower, the indoor environment is indicated to be less in water vapor, the fan gear of the indoor unit is reduced at the moment, the output of the cold amount in the indoor unit can be reduced, the low-temperature environment in the indoor unit is ensured, the condensation of the water vapor in the environment is facilitated, and the efficiency of forming the condensed water in the indoor unit is improved.

In one embodiment of the present application, the compressor frequency is adjusted according to the temperature in the evaporator tubes of the indoor unit, which may be adjusted as follows:

first, if the temperature in the evaporator tubes of the indoor unit is greater than a first set temperature, the compressor frequency is increased based on the current frequency of the compressor according to a first frequency magnitude.

Second, if the temperature in the evaporator tube of the indoor unit is less than or equal to the first set temperature and greater than or equal to the second set temperature, the current frequency of the compressor is stabilized.

Third, if the temperature in the evaporator tubes of the indoor unit is less than the second set temperature, the compressor frequency is reduced based on the current frequency of the compressor according to the second frequency magnitude.

In this application, the first frequency amplitude may be set to 4HZ to 6HZ.

In this application, the second frequency amplitude may be set to 1HZ to 6HZ.

In this application, according to the positive correlation between the compressor frequency and the temperature in the evaporator tube of the indoor unit, the compressor frequency is adjusted according to the temperature in the evaporator tube of the indoor unit, so that the efficiency of forming condensed water in the indoor unit can be improved, for example, when the temperature in the evaporator tube of the indoor unit is higher, the condensed water is not easy to form in the indoor unit, and at this time, the problem can be solved by adjusting the compressor frequency. Meanwhile, the energy consumption of the air conditioner in the self-cleaning treatment process can be reduced, for example, when the temperature in the evaporator tube of the indoor unit is low, the condition that condensed water is formed in the indoor unit is provided, at the moment, the compressor is not required to give excessive refrigeration, and the energy consumption of the air conditioner in the self-cleaning treatment process can be reduced by reducing the frequency of the compressor.

In order for those skilled in the art to better understand the present application, a specific embodiment will be described below with reference to fig. 7.

Referring to fig. 7, an overall flow chart of an air conditioner control method in an embodiment of the present application is shown, which includes an overall flow 700 of an air conditioner control method.

Firstly, when the air conditioning equipment operates in a self-cleaning mode, the angle of the air supply guide vane of the indoor unit can be adjusted to be R, so that condensed water is easier to generate in the indoor unit, then the indoor environment temperature is detected through the temperature sensor, the indoor relative humidity H is detected through the humidity sensor, and the dew point temperature A on the indoor side is obtained.

Then, whether the relative humidity H is larger than or equal to the first set humidity H1 can be judged through the indoor phase humidity H, if the relative humidity H is larger than or equal to H1, the relative humidity is considered to be larger, and at the moment, the fan gear of the indoor unit is adjusted to be a high gear, so that the phenomenon of condensation can be avoided, and condensed water can be generated rapidly. If the condition that the relative humidity H is greater than or equal to H1 is not satisfied, further judging whether the current relative humidity H is greater than the second set humidity H2 and less than H1 (the H1 value is greater than H2), and if the relative humidity H is truly between the H1 and H2 values, the fan gear of the indoor unit is a middle gear, so that the evaporation temperature can be properly reduced while ensuring relatively fast condensate water generation. When the above conditions (the relative humidity H is greater than H2 and less than H1) are not met, the fan gear of the indoor unit is adjusted to be in a low gear, the humidity is considered to be lower, and when the windshield is lowered, the evaporation temperature is lower, so that condensed water is generated.

And next, judging whether the temperature T in the evaporator tube of the indoor unit is greater than the dew point temperature A+t1, wherein T1 is a first dew point temperature correction value, if the temperature T in the evaporator tube of the indoor unit is greater than the dew point temperature A+t1 and meets the condition, considering that the evaporation temperature of the evaporator is not met, improving the capacity output, and further reducing the temperature in the evaporator tube, wherein the frequency B of the compressor is adjusted to be the current frequency B1 plus the first frequency amplitude B2. And if the temperature T in the evaporator tube of the current indoor unit is greater than the current dew point temperature A+t1, the next judgment is carried out. Judging that the temperature T in the evaporator tube is smaller than or equal to the current dew point temperature A+t1, and meanwhile, the temperature T in the evaporator tube is larger than or equal to the current dew point temperature A-T2, wherein T2 is a second dew point temperature correction value, and the temperature (A+t1) is considered to be larger than the temperature (A-T2); if the temperature T in the evaporator tube meets the condition, the current compressor frequency output is considered to be proper, and the current frequency B1 is maintained; otherwise, the compressor output is considered to be larger, the energy-saving effect is poor, and the compressor frequency B is adjusted to be the current frequency B1 minus the first frequency amplitude B3.

And next, detecting whether the temperature drop value is greater than or equal to F ℃ or not and whether the current indoor temperature TC1 is less than G ℃ or not according to the comparison of the current indoor environment temperature TC1 and the indoor environment temperature TC2 before E1 time, if so, considering that the comfort of a user is influenced to a certain extent, reducing the refrigerating output of air conditioning equipment, adjusting the frequency of a compressor to K% of the current frequency, reducing the capacity output value, and ensuring proper comfort.

Judging whether the temperature TN-C in the condenser tube of the outdoor unit is greater than t3, wherein t3 is a first target temperature correction value; if the temperature TN-C in the condenser tube of the outdoor unit is greater than t3 and meets the condition, the condensing effect is considered to be poor, the effect of quickly generating condensed water cannot be achieved, and at the moment, the frequency D of the fan of the outdoor unit is adjusted to be the current frequency D1 plus a third frequency amplitude D2; if the temperature TN-C in the condenser tube of the outdoor unit does not meet the condition of more than t3, the next step of judgment is carried out. Judging whether the temperature TN-C in the condenser tube of the outdoor unit is more than or equal to t4 and less than or equal to t3 meets the condition, and if so, maintaining the current frequency of the fan frequency D of the outdoor unit; if the temperature TN-C in the outdoor condenser tube is larger than or equal to the second target temperature correction value t4 and smaller than or equal to t3 and does not meet the condition, the outdoor condensing effect is considered to be too strong, energy saving is not facilitated, and the fan frequency D of the outdoor unit is adjusted to be the current frequency D1 minus the third frequency amplitude D.

And the current sensor can be used for detecting the fan current I of the indoor unit in real time. Judging whether the current I of the fan of the indoor unit is smaller than or equal to the value I1, the continuous running time of the compressor of the air conditioning equipment is longer than or equal to F, if not, the time and the quantity of condensed water generated by the air conditioning equipment are considered to be insufficient, detecting the internal environment temperature again after the interval time E2, judging the dew point temperature A by the relative humidity H, judging again by the whole control and executing related actions; if the condition is met, the air conditioning equipment enters the second stage control of the self-cleaning mode, and the control is ended.

In this embodiment, the above-described respective parameters may be set as follows:

wherein h1=85%, h2=55% is optimal; b2 B3=3 is optimal; t1, t2, t3, t4=1deg.C optimum; e1 =600 s, e2=30s is optimal; f=3 ℃ optimal; k=50 is optimal; g=22 ℃ optimal; c1 =15 ℃ optimal; x1=80, x1=60 is optimal; c2a=0 ℃, c2b= -5 ℃, c2c= -10 ℃ optimal; d2 =2hz, d3=3hz optimal; j=600s optimal; i1 =0.5a optimal.

It can be seen that, in the solution proposed in this embodiment, in the condensed water forming stage of the self-cleaning mode of the air conditioning apparatus, the gear position of the indoor unit fan, the frequency of the compressor, and the frequency of the outdoor unit fan are adjusted by referring to the positive correlation between the gear position of the indoor unit fan and the indoor relative humidity, the positive correlation between the frequency of the compressor and the temperature in the evaporator tube of the indoor unit, and the positive correlation between the frequency of the outdoor unit fan and the temperature in the condenser tube of the outdoor unit.
