Step S10: Obtain a cold and hot sense value, an indoor temperature value and an outdoor temperature value, and determine a target comfortable temperature according to the cold and heat sense value, the indoor temperature value and the outdoor temperature value;

In this embodiment, the execution subject is an air conditioner. The indoor temperature value and the outdoor temperature value can be obtained by a temperature sensor, and the cold and heat sense value can be set by the user. Among them, the cold and heat sensation value is the PMV value, which reflects the deviation degree of the human thermal balance, that is, the greater the positive value of the human thermal load, the more the human body feels hot, and the greater the negative value of the human thermal load, the more cold the human body feels. For ease of understanding, the following table illustrates the correspondence between the cold and hot sense values and comfort:

Table 1. Correspondence between hot and cold values and comfort

Hot and cold sense	comfortability
4<M≤6	heat
2<M≤4	A little hot
1<M≤2	warm
0≤M≤1	Comfortable (a little warm)
-1≤M<0	Comfortable (a bit cold)
-2<M≤-1	cool
-4<M≤-2	a little cold
-6≤M<-4	cold

Specifically, the cold and heat sense value can be calculated by the following formula:

PMV=[0.303exp(-0.036M)+0.0275]*{MW-3.05[5.733-0.007(MW)-P _a ]-0.42(MW-58.2)-0.0173M(5.867-P _a )-0.0014M(34 -t _a )-3.96*10f _cl [(t _cl +273)-(+273)]-f _cl h _c (t _cl -t _a )}

Among them, W is the mechanical work done by the human body, W/m ² ; M is the energy metabolism rate of the human body, which depends on the amount of human body activity, W/m ² ; t _cl is the outer surface temperature of the clothing, ℃; t _a is the human body ambient air temperature, ℃; P _a is the partial water vapor pressure around the body, kPa; h _c is the convective heat transfer ^{coefficient, W / (m 2 • K} ); fcl clothing is the area factor. Specific parameters can be detected according to devices such as infrared sensors, which will not be repeated in this application.

In this embodiment, the target comfort temperature may be determined according to the cold and heat sense value, the indoor temperature value, and the outdoor temperature value. Specifically, the comfort temperature required by the user (ie, t _a ) may be determined according to the set hot and cold sense values, and the comfort temperature is further corrected according to the indoor and outdoor temperature values to obtain the target comfort temperature.

Step S20: Obtain the user distance between the user and the air conditioner;

In this embodiment, the method for obtaining the distance between the user and the air conditioner may be: receiving the target air supply distance sent by the control terminal, and using the target air supply distance as the distance between the user and the air conditioner. The user can select the air supply range, such as high-end, mid-range and low-end, etc. Different gears correspond to different air supply distances; the user can also select the air supply distance, such as 2 meters, 4 meters, 6 meters, etc. Therefore, the distance between the user and the air conditioner can be used as the distance selected by the user or the air supply distance selected by the user.

Alternatively, the distance between the user and the air conditioner can be obtained through the distance detection device, that is, the user who detects the space of the air conditioner through the infrared sensor, radar sensor, etc., and the user and the air conditioner can be obtained through the radar sensor, infrared sensor, etc. The distance between.

Step S30. Adjust at least one of the frequency of the compressor of the air conditioner, the opening of the electronic expansion valve, and the rotation speed of the wind wheel of the cyclone according to the target comfort temperature and the user distance.

In this embodiment, the target comfortable temperature can be achieved by adjusting at least one of the frequency of the compressor of the air conditioner, the opening degree of the electronic expansion valve, and the rotation speed of the wind wheel of the cyclone fan.

Specifically, the difference between the temperature around the user and the target comfortable temperature is acquired in real time or periodically to adjust the frequency of the compressor of the air conditioner, the opening degree of the electronic expansion valve, and the cyclone according to the difference At least one of the rotation speeds of the wind wheels of the machine.

For example, in cooling mode, and the user is at a certain distance, if the difference is greater than or equal to the first preset temperature, the compressor operates at the maximum frequency allowed by the outdoor temperature value; if the difference is greater than the second preset temperature and less than the first preset Set the temperature, the compressor performs frequency reduction operation, frequency reduction every minute, each reduction is the first preset multiple of the original frequency; if the difference is greater than the third preset temperature and less than the second preset temperature, the compressor The minimum frequency allowed by the outdoor temperature value; if the difference is less than the third preset temperature, the number of electronic expansion valve steps increases, increasing the refrigerant circulation. When the maximum allowable opening is increased, if the difference is still less than the first 3. The preset temperature and the preset duration continue, the compressor stops; if the difference is greater than or equal to the second preset temperature, the compressor starts to run at the lowest frequency, if the difference continues to rise, the compressor is increased in frequency, and the frequency is increased once per minute, Each increase is the second preset multiple of the original frequency. The first preset multiple may be 0.9, the second preset multiple may be 1.1, the first preset temperature may be 3°C, the second preset temperature may be 1°C, and the third preset temperature may be -1°C , The preset duration can be 3 minutes. The target frequency of the compressor is also related to the user distance. For example, in the cooling mode, and when the difference is constant, the compressor frequency in the long-distance cooling state is greater than the compressor frequency in the short-distance cooling state.

In this embodiment, the air conditioner is provided with a first air outlet and a second air outlet. The electronic expansion valve includes a first electronic expansion valve and a second electronic expansion valve. The first electronic expansion valve is provided on the first For the air outlet, the second electronic expansion valve is provided at the second air outlet. The function of the electronic expansion valve is to control the refrigerant volume of the upper evaporator and the lower evaporator separately, to achieve the optimal refrigerant circulation volume under different air volumes, in order to achieve the best heat exchange. For example, when long-distance cooling is selected, 600 cubic air volume is required for the upper part of the evaporator and 300 cubic air volume is required for the lower part of the evaporator, which can be achieved by adjusting the opening degrees of the first electronic expansion valve and the second electronic expansion valve. The distribution of the opening of the electronic expansion valve is related to the air supply distance to the cyclone, so the opening of the electronic expansion valve can be distributed according to the user's distance, for example, the opening of the upper electronic expansion valve can be determined according to the user distance of the user farthest from the air conditioner , Determine the opening degree of the lower electronic expansion valve according to the user distance of the user closest to the air conditioner, or obtain the average user distance of multiple users, and determine the opening degree of the electronic expansion valve according to the average user distance.

The air conditioner includes an air outlet and a counter-rotating fan, and the counter-rotating fan sends air to the air outlet, and the counter-rotating fan includes at least two counter-rotating wind wheels. Further, the air conditioner is provided with a first air outlet and a second air outlet, the pair of cyclones includes a first pair of cyclones and a second pair of cyclones, and the first pair of cyclones blows toward the first The second pair of cyclones blows air toward the second air outlet, the height of the lower edge of the first air supply port from the bottom of the air conditioner is L1, and the lower side of the second air supply port The height of the edge from the bottom of the air conditioner is L2, and L1 is greater than L2. As shown in Figure 2, the principle of action on the cyclone fan is: after the air flow comes out of the first wind wheel 1, the reverse rotation of the second wind wheel 2 gives the air flow a reverse rotation speed, thereby offsetting the partial rotation speed of the air flow, and Reduced the ability to drive the surrounding air, which can increase the air supply distance. As shown in FIG. 3, the working principle of the double-pair cyclone fan is that different air supply distances can be achieved by adjusting the rotation speeds of the first pair of cyclone fans 10 and the second pair of cyclone fans 20.

When the user is a person, the distance between the user and the air conditioner can be used as the air supply distance of each pair of cyclones. For example, when the user is a person and the distance between the user and the air conditioner is 6 meters, the first Counter-rotating fan, and the speed of the first wind wheel is 500 rpm, the speed of the second wind wheel is 400 rpm, the third wind wheel of the second pair of cyclones is started, and the speed of the third wind wheel is 300 Rpm.

When there are many users, the distance between the user farthest from the air conditioner and the air conditioner can be used as the air supply distance of the first pair of cyclones, and the distance between the user closest to the air conditioner and the air conditioner can be used as the first The air supply distance of the two pairs of cyclones, for example, when there are two users, and the distance between the user and the air conditioner is 2 meters and 6 meters respectively, the first pair of cyclones is responsible for supplying 6 meters of users. The speed of one wind wheel is 500 rpm, the speed of the second wind wheel is 400 rpm, the second pair of cyclones is responsible for supplying 2 meters of users, and the speed of the third wind wheel is 100 rpm. The speed of the four wind wheels is 250 rpm. It should be noted that when there are multiple users, the average value of the distance between the multiple users and the air conditioner may be calculated, and the average value may be used as the air supply distance of the first pair of cyclones and the second pair of cyclones.

The correspondence between the air supply distance and the rotation speed of the wind wheel is preset. For example, when there are four users and the distance between the user and the air conditioner is 2 meters, 2.5 meters, 4 meters, and 6 meters, the first pair of cyclones is responsible for supplying the 6 meters of users. The speed is 500 rpm, the second wind wheel is 400 rpm, the second pair of cyclones is responsible for supplying 2 meters of users, the third wind wheel is 100 rpm, the fourth wind wheel The speed is 250 rpm.

Moreover, when the air supply distance is the same, the number of opening of the cyclone is different, and the rotation speed of the wind wheel is different. The user can select the pair of cyclones to be turned on, such as only the first pair of cyclones, only the second pair of cyclones, or the first pair of cyclones and the second pair of cyclones at the same time. According to the counter-rotating fan selected by the user, the rotation speed of the wind wheel is further determined.

It should be noted that the solution of this embodiment realizes that the wind speed reaching the user's location is greater than a preset value, where the preset value may be 0.3 m/s.

In the technical solution disclosed in this embodiment, the target comfort temperature is determined according to the cold and heat sense value, the indoor temperature value and the outdoor temperature value, the user distance between the user and the air conditioner is obtained, and the adjustment is performed according to the target comfort temperature and user distance At least one of the frequency of the compressor of the air conditioner, the opening degree of the electronic expansion valve, and the rotation speed of the wind wheel of the cyclone fan, thereby improving the accuracy of adjustment of the air conditioner.

In an embodiment, referring to FIG. 5, based on the embodiment shown in FIG. 4, the step of adjusting the frequency of the compressor of the air conditioner according to the target comfort temperature and the user distance includes:

Step S21: Obtain the temperature around the user in the space where the air conditioner is located;

Step S22: Determine the target frequency of the compressor according to the temperature around the user, the target comfortable temperature, and the user distance;

Step S23: Adjust the frequency of the compressor according to the target frequency.

In this embodiment, the temperature around the user in the space where the air conditioner operates can be obtained through infrared sensors, radar sensors, and other devices. It should be noted that the temperature around the user refers to the temperature within a preset range of the user's location, and the preset range may be a circle with a radius of 0.5 meters.

In this embodiment, the difference between the temperature around the user and the target comfort temperature is acquired in real time or at regular intervals; the target frequency of the compressor is determined according to the difference and the user distance.

For example, in cooling mode, and the user is at a certain distance, if the difference is greater than or equal to the first preset temperature, the compressor operates at the maximum frequency allowed by the outdoor temperature value; if the difference is greater than the second preset temperature and less than the first preset Set the temperature, the compressor performs frequency reduction operation, frequency reduction every minute, each reduction is the first preset multiple of the original frequency; if the difference is greater than the third preset temperature and less than the second preset temperature, the compressor The minimum frequency allowed by the outdoor temperature value; if the difference is less than the third preset temperature, the number of electronic expansion valve steps increases, increasing the refrigerant circulation. When the maximum allowable opening is increased, if the difference is still less than the first 3. The preset temperature and the preset duration continue, the compressor stops; if the difference is greater than or equal to the second preset temperature, the compressor starts to run at the lowest frequency, if the difference continues to rise, the compressor is increased in frequency, and the frequency is increased once per minute, Each increase is the second preset multiple of the original frequency. The first preset multiple may be 0.9, the second preset multiple may be 1.1, the first preset temperature may be 3°C, the second preset temperature may be 1°C, and the third preset temperature may be -1°C , The preset duration can be 3 minutes.

The target frequency of the compressor is also related to the user distance. For example, in the cooling mode, and when the difference is constant, the compressor frequency in the long-distance cooling state is greater than the compressor frequency in the short-distance cooling state.

In this embodiment, when there are multiple users in the space of the air conditioner, the average surrounding temperature is calculated according to the surrounding temperature of each of the users; based on the average surrounding temperature, the target comfortable temperature, and the The user distance determines the target frequency of the compressor.

Specifically, in the case of multiple users, the average ambient temperature of multiple users may be obtained, the difference between the average ambient temperature and the target comfort temperature may be calculated, and the compressor may be determined according to the difference and the user distance Target frequency. The user distance may be the distance between the user furthest away from the air conditioner and the air conditioner, or may be the distance between the user closest to the air conditioner and the air conditioner.

In the technical solution disclosed in this embodiment, the target frequency of the compressor is determined according to the temperature of the user's surroundings, the target comfortable temperature, and the distance of the user, and the frequency of the compressor is adjusted according to the target frequency, so that the accuracy of the cyclone fan is achieved control.
