The indoor temperature value and the outdoor temperature value can be acquired through the temperature sensor, and the cold and hot sensing values can be set by a user. The hot and cold feeling value, i.e. the PMV value, reflects the deviation degree of the human body heat balance, i.e. the human body feels hot as the positive value of the human body heat load is larger, and the human body feels cold as the negative value of the human body heat load is larger. For ease of understanding, the following table illustrates the correspondence between the cold and hot feel values and comfort:
TABLE 1 correlation between cold and hot feeling values and comfort
Specifically, the cold-heat feeling value can be calculated by the following formula:
PMV=[0.303exp(-0.036M)+0.0275]*{M-W-3.05[5.733-0.007(M-W)-Pa]-0.42(M-W-58.2)-0.0173M(5.867-Pa)-0.0014M(34-ta)-3.96*10fcl[(tcl+273)-(+273)]-fclhc(tcl-ta)}
wherein W is the mechanical work done by the human body, W/m2(ii) a M is human energy metabolism rate, which is determined by the activity of human body, W/M2;tclThe temperature of the outer surface of the garment is DEG C; t is taIs the temperature, DEG C, of the air around the human body; paThe partial pressure of water vapor around the human body is kPa; h iscIs the convective heat transfer coefficient, W/(m)2·K);fclIs the area factor of the garment. The specific parameters can be detected according to devices such as an infrared sensor, and the like, and the detailed description is omitted.
In this embodiment, the temperature can be controlled according to the sensed temperature, the indoor temperature and the outdoor temperatureA target comfort temperature is determined. Specifically, the comfortable temperature (i.e., t) required by the user may be determined according to the set cool and heat feeling valuea) And further correcting the comfortable temperature according to the indoor and outdoor temperature values to obtain the target comfortable temperature.
Step S20, obtaining the user distance between the user and the air conditioner;
in this embodiment, the manner of obtaining the distance between the user and the air conditioner may be: and receiving a target air supply distance sent by the control terminal, and taking the target air supply distance as the distance between the user and the air conditioner. The user can select air supply gears, such as high gear, middle gear, low gear and the like, and different gears correspond to different air supply distances; the user may also select the air supply distance, such as 2 meters, 4 meters, 6 meters, etc., and thus the distance between the user and the air conditioner may be determined according to the gear selected by the user or the air supply distance selected by the user.
Or, the distance between the user and the air conditioner is acquired through the distance detection device, that is, the user in the action space of the air conditioner can be detected through equipment such as an infrared sensor and a radar sensor, and the distance between the user and the air conditioner can be acquired through equipment such as a radar sensor and an infrared sensor.
And S30, adjusting at least one of a frequency of a compressor of the air conditioner, an opening degree of an electronic expansion valve, and a rotation speed of a wind wheel of the cyclone according to the target comfortable temperature and the user distance.
In the present embodiment, the target comfort temperature may be achieved by adjusting at least one of a frequency of a compressor of the air conditioner, an opening degree of the electronic expansion valve, and a rotation speed of a wind wheel of the cyclone.
Specifically, a difference between the temperature of the user's surroundings and a target comfort temperature is obtained in real time or at regular time to adjust at least one of a frequency of a compressor of the air conditioner, an opening degree of an electronic expansion valve, and a rotation speed of a wind wheel of a cyclone according to the difference.
For example, in the refrigeration mode, when the user distance is fixed, if the difference value is greater than or equal to the first preset temperature, the compressor operates according to the maximum frequency allowed by the outdoor temperature value; if the difference value is greater than the second preset temperature and less than the first preset temperature, the compressor performs frequency reduction operation, wherein the frequency is reduced once per minute, and the amplitude is reduced to a first preset multiple of the original frequency each time; if the difference value is greater than the third preset temperature and less than the second preset temperature, the compressor operates according to the minimum frequency allowed by the outdoor temperature value; if the difference value is less than the third preset temperature, the step number of the electronic expansion valve is increased, the refrigerant circulation quantity is increased, and when the opening degree is increased to the maximum allowable opening degree, if the difference value is still less than the third preset temperature and lasts for a preset time length, the compressor is stopped; if the difference value is larger than or equal to the second preset temperature, the compressor is started to operate at the lowest frequency, if the difference value continues to rise, the compressor rises frequency once per minute, and the rising amplitude of each time is the second preset multiple of the original frequency. Wherein the first preset multiple may be 0.9, the second preset multiple may be 1.1, the first preset temperature may be 3 ℃, the second preset temperature may be 1 ℃, the third preset temperature may be-1 ℃, and the preset time period may 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 frequency of the compressor in the long-distance cooling state is greater than the frequency of the compressor in the short-distance cooling state.
In this embodiment, the air conditioner is provided with a first air outlet and a second air outlet, and the electronic expansion valve includes a first electronic expansion valve and a second electronic expansion valve, where the first electronic expansion valve is disposed at the first air outlet, and the second electronic expansion valve is disposed at the second air outlet. The electronic expansion valve is used for respectively controlling the refrigerant quantity of the upper evaporator and the lower evaporator, so that the optimal refrigerant circulation quantity under different air quantities is realized, and the optimal heat exchange is realized. Such as: when the remote refrigeration is selected, 600 cubic air volumes are needed at the upper part of the evaporator, and 300 cubic air volumes are needed at the lower part of the evaporator, so that the remote refrigeration can be realized by adjusting the opening degrees of the first electronic expansion valve and the second electronic expansion valve. The opening of the electronic expansion valve is allocated according to the air supply distance to the cyclone machine, so that the opening of the electronic expansion valve can be allocated according to the user distance, for example, the opening of the upper electronic expansion valve is determined according to the user distance of the user farthest from the air conditioner, the opening of the lower electronic expansion valve is determined according to the user distance of the user closest to the air conditioner, or the average user distance of a plurality of users is obtained, and the opening of the electronic expansion valve is determined according to the average user distance.
The air conditioner comprises an air outlet and a counter-rotating fan, the counter-rotating fan supplies air to the air outlet, and the counter-rotating fan comprises two wind wheels which are arranged in a counter-rotating mode. Further, the air conditioner is provided with a first air outlet and a second air outlet, the counter-rotating fan comprises a first pair of cyclones and a second pair of cyclones, the first pair of cyclones supplies air to the first air outlet, the second pair of cyclones supplies air to the second air outlet, the height from the lower edge of the first air supply outlet to the bottom of the air conditioner is L1, the height from the lower edge of the second air supply outlet to the bottom of the air conditioner is L2, and L1 is larger than L2. As shown in fig. 2, the principle of action on the cyclone is as follows: after the air current comes out from first wind wheel 1, the contrary direction of second wind wheel 2 is rotated and is given the contrary speed of circling around of air current to offset the partial speed of circling around of air current, and then reduced the ability to surrounding air drive, thereby can improve the air supply distance. As shown in fig. 3, the operating principle of the double-pair cyclone is as follows: by adjusting the rotation speed of the first pair of cyclones 10 and the rotation speed of the second pair of cyclones 20, different blowing distances can be achieved.
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 cyclone fans, for example, when the user is a person and the distance between the user and the air conditioner is 6 meters, the first pair of cyclone fans is started, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the third wind wheel of the second pair of cyclone fans is started, and the rotating speed of the third wind wheel is 300 rpm.
When the user is a plurality of people, 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 air supply distance of the second pair of cyclones, for example, when the user is two people and the distances between the user and the air conditioner are 2 meters and 6 meters respectively, the first pair of cyclones are responsible for supplying air to the user with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones are responsible for supplying air to the user with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm. When the user is a plurality of users, an average value of distances between the plurality of users and the air conditioner may be calculated, and the average value may be used as the blowing distances of the first pair of cyclones and the second pair of cyclones.
The corresponding relation between the air supply distance and the rotating speed of the wind wheel is preset. For example, when the users are four people and the distances between the users and the air conditioner are 2 meters, 2.5 meters, 4 meters and 6 meters respectively, the first pair of cyclones is responsible for supplying air to the users with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones is responsible for supplying air to the users with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm.
And when the air supply distance is consistent, the opening number of the counter-rotating fans is different, and the rotating speeds of the wind wheels are different. The user can select the opened pair of cyclones, such as only opening the first pair of cyclones, only opening the second pair of cyclones, or simultaneously opening the first pair of cyclones and the second pair of cyclones. And further determining the rotating speed of the wind wheel according to the contra-rotating fan which is selected to be started by a user.
It should be noted that the solution of the present embodiment realizes that the wind speed reaching the position of the user is greater than a preset value, wherein the preset value may be 0.3 m/s.

For example, in the refrigeration mode, when the user distance is fixed, if the difference value is greater than or equal to the first preset temperature, the compressor operates according to the maximum frequency allowed by the outdoor temperature value; if the difference value is greater than the second preset temperature and less than the first preset temperature, the compressor performs frequency reduction operation, wherein the frequency is reduced once per minute, and the amplitude is reduced to a first preset multiple of the original frequency each time; if the difference value is greater than the third preset temperature and less than the second preset temperature, the compressor operates according to the minimum frequency allowed by the outdoor temperature value; if the difference value is less than the third preset temperature, the step number of the electronic expansion valve is increased, the refrigerant circulation quantity is increased, and when the opening degree is increased to the maximum allowable opening degree, if the difference value is still less than the third preset temperature and lasts for a preset time length, the compressor is stopped; if the difference value is larger than or equal to the second preset temperature, the compressor is started to operate at the lowest frequency, if the difference value continues to rise, the compressor rises frequency once per minute, and the rising amplitude of each time is the second preset multiple of the original frequency. Wherein the first preset multiple may be 0.9, the second preset multiple may be 1.1, the first preset temperature may be 3 ℃, the second preset temperature may be 1 ℃, the third preset temperature may be-1 ℃, and the preset time period may be 3 minutes.
