Referring to fig. 2, a first embodiment of the present invention provides an air conditioner control method including:
step S10, detecting the current indoor environment temperature value;
the current indoor environment temperature value can be obtained by detecting the return air temperature of the indoor unit of the air conditioner, for example, a temperature sensor is arranged at the return air inlet of the indoor unit of the air conditioner for detection; or, this indoor environment temperature value also can be detected by the temperature sensor who sets up on other devices in the indoor environment that the air conditioner was located, for example the temperature sensor on the wearable equipment (for example bracelet) that the user wore detects and obtains, and the temperature that this wearable equipment detected and obtains is user's ambient temperature, and is more accurate.
Step S20, judging whether the indoor environment temperature value is less than a first preset temperature value;
the first preset temperature value is used as a judgment standard for judging whether the internal fan needs to reduce energy consumption to operate or not. Preferably, the first preset temperature value may be set to 31 ℃. When the indoor environment temperature value is less than 31 ℃, the indoor environment temperature value at the moment can be considered to be closer to a target temperature value set by a user, and the indoor fan can meet the temperature drop requirement of the indoor environment when the air speed is reduced; when the indoor environment temperature value is greater than or equal to 31 ℃, the difference between the indoor environment temperature value at the moment and the target temperature value set by the user is considered to be large, and rapid cooling is needed. The first preset temperature value can be set according to the actual use condition of the user so as to meet the use requirement of the user. When the indoor environment temperature value is less than the first preset temperature value, the following steps S30 and S40 are sequentially executed; when the indoor ambient temperature value is greater than or equal to the first preset temperature value, the following step S50 is performed.
Step S30, determining the energy-saving wind speed value of the fan in the air conditioner and the opening values of the upper and lower wind guide strips corresponding to the indoor environment temperature value according to the indoor environment temperature value;
in order to reduce the energy consumption of the air conditioner and ensure the comfort of users, the mapping relation between different indoor environment temperature values and the energy-saving air speed value of a fan in the air conditioner and the opening values of the upper air guide strip and the lower air guide strip can be established in advance. The upper and lower air guide strips are components of an air outlet of the air conditioner for controlling the air outlet angle of the air conditioner in the vertical direction. In the mapping relation, each indoor environment temperature value corresponds to one energy-saving wind speed value and one opening value. The energy-saving air speed value is lower than the current running air speed of the fan in the air conditioner, so that the air speed value of the inner fan can be adaptively adjusted along with the change of the indoor environment temperature value, and the energy consumption of the fan in the air conditioner is reduced. The opening degree value of the upper and lower air guide strips is larger than the minimum opening degree value of the upper and lower air guide strips during the operation of the air conditioner and smaller than the maximum opening degree value which can be opened by the upper and lower air guide strips during the operation of the air conditioner or smaller than the maximum opening degree value set by a user, so that the opening degree value of the upper and lower air guide strips can be adaptively adjusted along with the change of the indoor environment temperature value in the maximum opening degree value selected by the user, and the comfort requirement of the user can be met under the condition of energy conservation.
The mapping relation can be obtained by methods such as data fitting, empirical values, computer simulation and the like, and can be adapted to different temperature drop requirements, different heat exchange efficiencies of air conditioners, different use requirements of users and the like, so that the requirement of comfort of the users can be met after the wind speed of the inner fan is reduced. The expression form of the mapping relation can be a chart, a formula, a table and the like.
The specific numerical values of the energy-saving wind speed value and the opening values of the upper and lower wind guide strips corresponding to each indoor environment temperature value can be set according to the actual use requirements of users. Specifically, the energy-saving wind speed value can have a variation trend which is reduced along with the reduction of the indoor environment temperature value, and/or the opening value of the upper and lower wind guide strips can have a variation trend which is reduced along with the reduction of the indoor environment temperature value, so that the air output of the inner fan is reduced along with the reduction of the indoor environment temperature value, and the comfort of a user is ensured.
Based on the mapping relation, after the indoor environment temperature is detected, the corresponding energy-saving wind speed value and the corresponding opening value can be determined directly according to the indoor environment temperature.
And step S40, controlling the inner fan and the upper and lower air guide strips of the air conditioner to operate according to the energy-saving air speed value and the opening value respectively so as to reduce the energy consumption of the air conditioner.
Controlling the inner fan to operate according to the energy-saving air speed value, wherein the energy-saving air speed value is lower than the current operating air speed of the inner fan, so that the energy consumption of the air conditioner is reduced; the upper and lower air guide strips are controlled to operate according to the opening value, so that the comfort of a user can be improved.
And step S50, controlling the inner fan and the upper and lower air guide strips of the air conditioner to operate according to the maximum wind speed value and the maximum opening value respectively.
When the indoor environment temperature value is greater than the first preset temperature value, the indoor environment temperature is considered to be higher, and the difference between the indoor environment temperature and the target value of the user comfort temperature is larger. In order to meet the comfort of users, the inner fan of the air conditioner can be operated according to normal wind speed without considering energy conservation, and meanwhile, the opening degree of the upper and lower air guide strips can be not adjusted and opened according to the setting of the users or the control parameters of the system. Preferably, in order to further increase the cooling speed of the indoor environment, the inner fan of the air conditioner can be controlled to operate according to the highest wind speed value; in addition, the upper and lower wind-guiding strips of air conditioner can be opened according to the maximum opening value to realize the biggest air output and let the user obviously experience the sense of wind. The maximum wind speed value can be the maximum wind speed value which can be reached by the operation of the inner fan, and can also be the maximum wind speed value which is limited by the inner fan in the wind speed gear set by a user; the maximum opening value can be the maximum opening degree which can be reached by the upper and lower air guide strips, and can also be the maximum opening degree which is limited by the upper and lower air guide strips in the wind direction set by the user.
The current indoor temperature value can be obtained in real time or in a timing mode. The current indoor temperature value is obtained in real time, the energy-saving wind speed value is determined according to the current indoor temperature value, and the inner fan can be kept in a low-energy consumption state all the time, so that the energy consumption of the air conditioner is reduced; the current indoor temperature value is obtained regularly, the energy-saving wind speed value and the opening value are determined according to the current indoor temperature value, and the total energy consumption of the indoor fan can be reduced to a certain extent, so that the energy consumption of the air conditioner is reduced, and the comfort of a user can be improved to a certain extent. In addition, the current indoor temperature value can be acquired when an energy-saving instruction is received, the energy-saving wind speed value and the opening value are determined according to the current indoor temperature value, the energy-saving instruction can be sent by a user, the energy consumption of the inner fan can be reduced when the user needs the inner fan, and the upper air guide strip and the lower air guide strip can be adaptively adjusted to ensure the comfort of the user.
The control method of the air conditioner provided in this embodiment detects the current indoor environment temperature value, determines whether the indoor environment temperature value is smaller than a first preset temperature value, the first preset temperature value is a temperature critical value set according to the comfort of the user, when the indoor environment temperature value is less than the first preset temperature value, the current indoor environment temperature can be considered to be closer to the target temperature value set by the user, determining the energy-saving wind speed value of the inner fan of the air conditioner and the opening values of the upper and lower air guide strips corresponding to the indoor environment temperature value according to the indoor environment temperature value, controlling the inner fan of the air conditioner and the upper and lower air guide strips to operate according to the energy-saving wind speed value and the opening value respectively, wherein the energy-saving wind speed value of the inner fan is smaller than the current operation wind speed value, the air conditioner can reduce the energy consumption, and in addition, the opening degree value of the upper and lower air guide strips can be adjusted according to the indoor environment temperature value adaptability, so that the comfort of a user is ensured. When the indoor environment temperature value is greater than or equal to the first preset temperature value, the air conditioner inner fan and the upper and lower air guide strips are controlled to operate according to the maximum air speed value and the maximum opening value respectively, so that the indoor environment temperature can be rapidly reduced, and a user can rapidly feel the wind sensation. The air conditioner can reduce the energy consumption of the air conditioner by the aid of the adaptive wind speed reduction of the air blower according to different indoor environment temperature values in the air conditioner in the above mode, and meanwhile, the opening degree of the upper and lower wind guide strips is adjusted according to different indoor environment temperature values, so that comfort of a user is guaranteed, and the energy consumption of the air conditioner is reduced while comfort requirements of the user are guaranteed.
Referring to fig. 3, a second embodiment of the present invention is proposed based on the first embodiment, and in this embodiment, the step of determining the energy-saving wind speed value of the fan in the air conditioner corresponding to the indoor environment temperature value according to the indoor environment temperature value in the first embodiment specifically includes the following steps:
step S31, calculating an energy-saving wind speed value according to the indoor environment temperature value and a preset formula; and inquiring an opening rule table of the upper and lower air guide strips according to the indoor environment temperature value to determine the opening values of the upper and lower air guide strips of the air conditioner.
The method for determining the energy-saving air speed value through the indoor environment temperature value has various methods, and specifically, the mapping relation between different indoor environment temperature values and the energy-saving air speed value of the fan in the air conditioner can be stored in a database in a preset formula mode through table lookup, calculation and the like, and when the indoor environment temperature value is smaller than the preset temperature value, the energy-saving air speed value of the fan in the air conditioner can be obtained through calculation of the preset formula according to the different indoor environment temperature values.
The preset formula may be in various forms, and the indoor ambient temperature value and the energy-saving wind speed value are variables in the formula, and may be specifically V ═ b × T-a, V ═ a × b × T, V ═ a + b × T + c × T2And the fitting method can be the same, the fitting requirements can be different, and the like, and the fitting method can be different, wherein V is an energy-saving wind speed value, a is a fixed parameter, b and c are adjusting parameters, the adjusting parameters can be multiple, and T is an indoor environment temperature value. During fitting, the fixed parameter a can select the values of the current wind speed, the highest wind speed and other air conditioner operation parameters of the inner fan, and the values of the adjustment parameters b and c are determined by taking the fixed parameter a as a fixed quantity and the known indoor environment temperature and energy-saving wind speed values to determine a preset formula so as to reduce the wind speed of the inner fan; and the numerical values of a, b and c can be directly obtained by directly fitting the known indoor environment temperature and the energy-saving wind speed value, so that a preset formula is obtained.
Specifically, the energy-saving air speed value of the fan in the air conditioner can be calculated through a preset formula V, wherein the value range of the fixed parameter a is [4.2, 6.2], the value range of the adjusting parameter b is [0.1, 0.3], and when the parameters a, b and c are in the value ranges, the energy consumption of the air conditioner can be effectively reduced and the comfort requirement of a user can be met. Preferably, in the value range, when the preset formula is V ═ 0.2T-5.2, the inner fan operates according to the energy-saving air speed value determined by the preset formula, so that the energy efficiency ratio of the air conditioner is highest.
Referring to fig. 4, specifically, the step of calculating the energy-saving wind speed value according to the indoor environment temperature value by using a preset formula includes the following steps:
step S311, calculating a wind speed adjusting variable according to the indoor environment temperature value through a preset formula;
and S312, calculating an energy-saving wind speed value through a preset formula according to the wind speed adjusting variable and the fixed parameter.
In the predetermined formula, the indoor ambient temperature value and its adjustment parameters constitute the wind speed adjustment variable, such as the above-mentioned b × T, b × T + c × T2And the like. After the wind speed adjusting variable is calculated according to the detected indoor environment temperature value through the preset formula, the energy-saving wind speed value can be calculated according to the calculation relation between the wind speed adjusting variable and the fixed parameter in the preset formula, wherein the calculation relation can be addition, subtraction, multiplication, division and the like, and is specifically determined according to the setting of the preset formula.
The method for determining the energy-saving wind speed value through the indoor environment temperature value has various methods, and the mapping relation between different indoor environment temperature values and the opening values of the upper and lower air guide strips of the air conditioner can be specifically stored in a database in a table form through table lookup, calculation and the like, for example, an opening rule table of the upper and lower air guide strips is established. And looking up a table according to the indoor environment temperature value, and determining the corresponding opening degree values of the upper and lower air guide strips through the mapping relation in the table. Referring to fig. 5, the step of determining the opening degree values of the upper and lower air guide strips of the air conditioner by querying the opening degree rule table of the upper and lower air guide strips according to the indoor environment temperature value includes the following steps:
step S313, inquiring an opening rule table of the upper and lower air guide strips, and judging whether corresponding indoor environment temperature values exist in the opening rule table of the upper and lower air guide strips;
step S314, if yes, directly matching corresponding opening values of the upper and lower air guide strips according to the indoor environment temperature value;
step S315, if not, searching an approximate indoor environment temperature value with the minimum difference value with the indoor environment temperature value in an opening rule table of the upper and lower air guide strips;
and step S316, matching corresponding opening values of the upper and lower air guide strips according to the approximate indoor environment temperature value.
The opening rule table of the upper and lower air guide strips can comprise indoor environment temperature values and specific numerical values of the openings of the upper and lower air guide strips, and each indoor environment temperature value corresponds to a specific numerical value of the opening of the upper and lower air guide strips.
In addition, the upper and lower air guide strip opening rule table can also comprise calculation formulas of indoor environment temperature values and opening values of the upper and lower air guide strips, and each indoor environment temperature value corresponds to one calculation formula of the opening value of the upper and lower air guide strips. In the calculation formula, the opening values of the upper and lower air guide strips can be calculated by the operation parameters of the air conditioner (such as the maximum opening value or the minimum opening value of the upper and lower air guide strips, the current operation wind speed value of the inner fan and the like), the setting parameters of the user (such as the set wind speed gear, the set wind directions of the upper and lower air guide strips, the set indoor environment temperature values in the opening rule table of the upper and lower air guide strips and the like) or other parameters.
In the opening rule table of the upper and lower air guide strips, the indoor environment temperature value and the corresponding opening value of the upper and lower air guide strips or the number of calculation formulas of the upper and lower air guide strips are required to be as large as possible so as to meet more working conditions. The opening degree values of the upper and lower air guide strips can be set according to actual use requirements, preferably, in the opening degree rule table of the upper and lower air guide strips, the opening degree values of the upper and lower air guide strips can be reduced along with the reduction of the indoor environment temperature value, and the upper and lower air guide strips of the air conditioner can be adjusted to adapt to the difference of the indoor environment temperature values, so that the comfort of users is ensured. Furthermore, when the indoor environment temperature is lowered to a certain temperature value, such as a target temperature value set by a user, the opening degree value of the upper and lower air guide strips can be set to be the minimum opening degree of the upper and lower air guide strips, so that the comfort of the user is further improved.
As shown in table 1, the upper and lower air guide bar opening degree rule table includes a plurality of indoor environment temperatures less than a first preset temperature value and calculation formulas of corresponding upper and lower air guide bar opening degree values, where H ismaxIs the most of the upper and lower wind guide stripsLarge opening value, HminAnd N is the total number of indoor environment temperature values in the opening rule table of the upper and lower air guide strips. Wherein HmaxAnd HminThe two limit values of the upper and lower air guide strips can be reached when the air conditioner operates, the two limit values of the lower and upper air guide strips can be set for the current user, and the operation parameters of other air conditioners can be set according to the actual setting. Specifically, the indoor environment temperature value in the opening rule table of the upper and lower air guide strips can be set by default for the air conditioner, and can also be determined by acquiring the setting parameters of the user. As shown in Table 1, as the indoor environment temperature value decreases, the upper and lower air guide strips are Hmax-HminThe opening degree values of the upper and lower air guide strips are reduced in an equal proportion mode, the adaptability of the opening degree values of the upper and lower air guide strips can be adjusted along with the change of N, specifically, along with the increase of N, the reduction range of the opening degree values of the upper and lower air guide strips adjacent to each other can be correspondingly reduced along with the reduction of the indoor environment temperature value, and therefore the adaptability of the opening degree values of the upper and lower air guide strips to different indoor environment temperature values is met. When the indoor environment temperature value is set by a user, the opening degree values of the upper and lower air guide strips can be intelligently adjusted according to the setting parameters of the user, so that the use requirements of the user are met. Preferably, the indoor environment temperature values in the opening rule tables of the upper and lower air guide strips may be set to have equal difference between adjacent temperature values, for example, the difference is 1 ℃, so as to ensure the adaptability of the operation rule.
When the detected indoor environment temperature value has corresponding data in the upper and lower air guide strip opening rule table, the corresponding upper and lower air guide strip opening values are directly matched according to the indoor environment temperature value. For example, when the detected indoor environment temperature value is 30 ℃, the table 1 is queried, and if the corresponding indoor environment temperature exists, the calculation formula of the opening values of the upper and lower air guide strips corresponding to 30 ℃ can be matched through the table 1 to be Hmin+4/5(Hmax-Hmin) And the value of N is determined to be 5 by the table 1, and the maximum opening value and the minimum opening value of the upper air guide strip and the lower air guide strip of the air conditioner are obtainedAnd the opening value can be determined according to the opening value of the upper and lower air guide strips at the moment.
When the detected indoor environment temperature value has no corresponding data in the upper and lower air guide bar opening rule tables, the approximate indoor environment temperature value with the minimum difference value with the indoor environment temperature value is searched in the tables, if the approximate indoor environment temperature value can be determined by a rounding method and a minimum difference method, and after the approximate indoor environment temperature value is determined, the upper and lower air guide bar opening values are matched according to the approximate indoor environment temperature value. For example, when the detected indoor environment temperature value is 29.3 ℃, the table 1 is inquired, and if there is no corresponding indoor environment temperature value, the data 29 ℃ closest to the indoor environment temperature value can be searched in the table by a rounding method, and then 29 ℃ is the approximate indoor environment temperature; in addition, the approximate indoor environment temperature value can be determined by using a minimum difference method, and the temperature interval of 29.3 ℃ in the table 1 is determined to be [29,30 ]]By making a difference between the 29 c and 30 c end values of the 29.3 c interval, respectively, according to the minimum difference method, 29 c is the data closest to the current indoor environment temperature value, and 29 c is the approximate indoor environment temperature value. The calculation formula for determining the opening degree values of the upper and lower air guide strips by approximating the indoor environment temperature value of 29 ℃ is Hmin+3/N(Hmax-Hmin) The value of N can be determined to be 5 by the table 1, and the opening values of the upper and lower air guide strips at the moment can be determined by acquiring the maximum opening value and the minimum opening value of the upper and lower air guide strips of the air conditioner.
In addition, in addition to determining the approximate ambient temperature, when the detected indoor ambient temperature value has no corresponding data in the upper and lower air guide bar opening rule tables, the air conditioner may not make any response, and the upper and lower air guide bars are operated according to the current opening.
According to the air conditioner control method, the energy-saving air speed value of the inner fan can be calculated according to the indoor environment temperature value through a preset formula, the opening degree values of the upper and lower air guide strips can be determined by inquiring the opening degree rule table of the upper and lower air guide strips according to the indoor environment temperature value, and through the mode, the corresponding energy-saving air speed value and the corresponding opening degree value can be determined according to different indoor environment temperature values, so that the energy consumption of the air conditioner is reduced while the comfort of a user is guaranteed.

if not, determining the energy-saving wind speed value of the fan in the air conditioner and the opening values of the upper and lower air guide strips corresponding to the indoor environment temperature value according to the indoor environment temperature value.
The second preset temperature value can be a target temperature of the indoor environment and can be determined by acquiring setting parameters of a user, preferably, the second preset temperature value can be 26 ℃, and if the current indoor environment temperature value is greater than the second preset temperature value, the wind speed value of an inner fan of the air conditioner and the opening values of the upper air guide strip and the lower air guide strip are adjusted to adapt to the indoor environment temperature value, so that the comfort of the user is guaranteed, and meanwhile, the energy consumption of the air conditioner is reduced; if the current indoor environment temperature value is less than or equal to the second preset temperature value, the current indoor environment temperature can be considered to meet the comfort requirement of the user, further cooling is not needed, and the inner fan and the upper and lower air guide strips of the air conditioner can be operated at low wind speed and low opening degree or can be closed so as to further reduce energy consumption. Preferably, the fan in the air conditioner can be controlled to operate according to the lowest wind speed value, the lowest wind speed value can be specifically set according to actual conditions, and the fan can operate constantly at the lowest wind speed value to maintain the stability of the indoor environment temperature, so that the energy consumption is reduced, and the comfort of users is ensured; meanwhile, the upper and lower air guide strips of the air conditioner can be controlled to operate according to the minimum opening value, so that the comfort of a user is improved.

When the operation mode of the air conditioner is not the energy-saving mode, the inner fan and the upper and lower air guide strips can operate according to normal parameters.
By the mode, a user can control the air conditioner to enter an energy-saving mode when the energy-saving requirement exists, so that the energy consumption of the air conditioner is reduced; the user can control the air conditioner to operate according to the normal mode of the non-energy-saving mode when no energy-saving requirement exists, and the air conditioner operates according to the normal operation rule according to the current setting of the user so as to further meet the comfort requirement and realize different use requirements of the user.
