Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
After the preset temperature is set by the current user on the air conditioning equipment, the air conditioning equipment supplies air outwards according to the preset frequency, and the average temperature of the indoor space is adjusted to the preset temperature in a certain time. In some situations, the user needs to adjust the air outlet temperature of the air conditioning device, such as to obtain a cooler or warmer temperature at the air outlet relative to a predetermined temperature, such as a rapid cooling after strenuous exercise in summer, or a warmer warm air in winter, etc. However, the air conditioning apparatus in the related art can only control the average temperature of the indoor space to be consistent with the preset temperature set by the user, and cannot set and adjust the air outlet temperature near the air outlet, so that the requirements of the user on local rapid heating and cooling cannot be met, and the user experience is poor.
In order to solve the above technical problems, the present disclosure provides a control method of an air conditioning apparatus, by acquiring set indoor temperature information and target air outlet temperature information, and referring to the indoor temperature information and the reference air outlet temperature information, a first correction frequency of a compressor is obtained based on first preset configuration information, a first deviation value and a second deviation value, so that an operation frequency of the compressor is adjusted, a relatively warmer or cooler area can be provided near an air outlet of the air conditioning apparatus, a requirement that a user hopes local rapid refrigeration or heating is satisfied, and a use experience of the user is improved.
An exemplary embodiment of the present disclosure provides a control method of an air conditioning apparatus, as shown in fig. 1, including:
s100, acquiring set indoor temperature information and target air outlet temperature information;
S200, acquiring reference indoor temperature information and reference air outlet temperature information, wherein the reference indoor temperature information is the temperature of an indoor environment obtained through detection, and the reference air outlet temperature information is the temperature of an air outlet obtained through detection;
S300, obtaining a first correction frequency of the compressor according to a first deviation value between the set indoor temperature information and the reference indoor temperature information and a second deviation value between the target air-out temperature information and the reference air-out temperature information based on first preset configuration information, wherein the first preset configuration information is used for representing the corresponding relation between the first deviation value and the second deviation value and the first correction frequency of the compressor;
S400, adjusting the operation frequency of the compressor based on the first correction frequency of the compressor.
In step S100, the setting room temperature information T 1 is target average temperature or gear information related to the target average temperature that the air-conditioning apparatus operates to bring the indoor environment in which it is located to. The set indoor temperature information T 1 is generally inputted by a user, and is a temperature that the user wants the indoor environment to reach. The target outlet air temperature information T 2 is an average temperature at which the air conditioning apparatus operates so that a partial area of an outlet of the air conditioning apparatus reaches or gear information related to the average temperature. The user may set the temperature information of the air conditioning apparatus through an input device of the air conditioning apparatus, which may be, for example, a remote controller, an application program in a terminal apparatus, or the like. After the user sets the set indoor temperature information T 1 and the target outlet air temperature information T 2 in the input device of the air conditioning apparatus, the control device of the air conditioning apparatus receives the set indoor temperature information T 1 and the target outlet air temperature information T 2.
In step S200, the reference indoor temperature information T 3 is the temperature of the indoor environment at the present time obtained by the detection method, and the reference outlet temperature information T 4 is the temperature of the area at or near the outlet at the present time obtained by the detection method. The reference indoor temperature information T 3 can be obtained by detecting the temperature sensor on the air conditioning equipment in real time or at certain preset time intervals, or can be obtained by detecting other temperature sensors arranged indoors in real time or at certain preset time intervals and then transmitted to the air conditioning equipment. The reference outlet air temperature information T 4 may be obtained by real-time detection or successive detection at a predetermined time interval through a temperature sensor provided at or near an outlet of the air conditioning apparatus.
In step S300, the first preset configuration information may be set in the air-conditioning apparatus when the air-conditioning apparatus leaves the factory, or may be stored in the cloud server, and may be retrieved from the cloud server to be executed in the air-conditioning apparatus when the first preset configuration information needs to be used.
The first preset configuration information is associated with a compressor correction frequency. The compressor can pump the refrigerant from the low-pressure area, then compress the refrigerant and send the refrigerant to the high-pressure area for compression, and the module output frequency and voltage of the three-phase induction motor in the compressor are controlled to adjust the compression speed of the refrigerant in the compressor, so that the refrigeration or heating speed of the air conditioning equipment is controlled.
According to a first deviation value DeltaT 1 between the set indoor temperature information T 1 and the reference indoor temperature information T 3 and a second deviation value DeltaT 2 between the target air outlet temperature information T 2 and the reference air outlet temperature information T 4, a first correction frequency F of the compressor is obtained, and the first preset configuration information is used for representing the corresponding relation between the first deviation value DeltaT 1 and the second deviation value DeltaT 2 and the first correction frequency F of the compressor. That is, the first deviation value Δt1 calculated according to the set indoor temperature information T 1 and the reference indoor temperature information T 3 obtained by each detection, the second deviation value Δt2 calculated according to the target outlet air temperature information T 2 and the reference outlet air temperature information T 4 obtained by each detection, and the first deviation value Δt1 and the second deviation value Δt2 obtained each time are compared with each preset threshold value in the first preset configuration information, so as to obtain the first correction frequency F of the corresponding compressor, and the first correction frequency F of the compressor is used for modification based on the frequency of the current operation of the compressor, so as to adjust the refrigerating or heating speed of the air conditioning device.
For example, after the air conditioning apparatus operates for a period of time, for example, 10 minutes, or after exiting the open loop control, the detection and acquisition of the reference indoor temperature information T 3 and the reference outlet air temperature information T 4 may be started, and the detection interval time of the reference indoor temperature information T 3 and the reference outlet air temperature information T 4 may be detected every 3 minutes, so that the first deviation value Δt1 and the second deviation value Δt2 may be timely obtained, and whether the outlet air temperature at the current moment reaches the user requirement may be timely detected, so that the first correction frequency F of the compressor may be timely adjusted, and the user experience may be improved.
Here, in the present embodiment, the first correction frequency F of the compressor is used for the compressor to perform the rapid cooling or heating at the air outlet, and at the same time, the second correction frequency (described in detail later) of the compressor is obtained according to the set indoor environment temperature and the temperature change rate in the indoor environment, and the operation frequency of the compressor is adjusted using the second correction frequency of the compressor. The use of the first correction frequency F of the compressor and the second correction frequency F of the compressor to jointly adjust the operating frequency of the compressor is not contradictory, both of which can be performed simultaneously or alternatively.
In some possible embodiments, the first deviation value Δt1 is an absolute value of a difference between the set indoor temperature information T 1 and the reference indoor temperature information T 3.
Illustratively, the first deviation value Δt1 is represented as:
△T1＝|T1–T3|
Since the air conditioning apparatus will adjust the reference indoor temperature information T 3 to the set indoor temperature information T 1, after reaching or approaching the desired set indoor temperature information T 1, the frequency of the compressor will be automatically adjusted so that the indoor temperature is maintained at the set indoor temperature information T 1, and no supercooling or overheating will occur. Therefore, in general, when the first deviation value Δt1 is larger, the difference between the indoor environment temperature at the present time and the indoor environment temperature required by the user is larger, and the frequency of the compressor needs to be adjusted to increase the cooling or heating speed of the air conditioning apparatus.
In some possible embodiments, when the preset mode is the cooling mode, the second deviation value Δt2 is a difference value between the reference outlet air temperature information T 4 and the target outlet air temperature information T 2; when the preset mode is a heating mode, the second deviation value Δt2 is a difference value between the target outlet air temperature information T 2 and the reference outlet air temperature information T 4.
In the embodiment, in the cooling mode, if the second deviation value Δt2 is a positive value, it means that the target air outlet temperature information T 2 is lower than the reference air outlet temperature information T 4, which indicates that the air outlet temperature at the air outlet does not reach the cooling degree required by the user, and the first correction frequency F of the compressor is required to be used for adjusting the operation frequency of the compressor, so as to accelerate the cooling speed of the air conditioning device. In the heating mode, if the second deviation value Δt2 is a positive value, it means that the target air outlet temperature information T 2 is higher than the reference air outlet temperature information T 4, which indicates that the air outlet temperature at the air outlet is not warm enough, and the first correction frequency F of the compressor needs to be used to adjust the operation frequency of the compressor, so as to accelerate the heating speed of the air conditioning equipment.
In the cooling mode, if the second deviation value Δt2 is negative, it means that the target air outlet temperature information T 2 is higher than the reference air outlet temperature information T 4, which indicates that the air outlet temperature at the air outlet exceeds the cooling requirement of the user, and the first correction frequency F of the compressor needs to be used to adjust the operation frequency of the compressor, so as to slow down the cooling speed of the air conditioning device. In the heating mode, if the second deviation value Δt2 is negative, it means that the target air outlet temperature information T 2 is lower than the reference air outlet temperature information T 4, which indicates that the air outlet temperature at the air outlet is too warm, and the first correction frequency F of the compressor needs to be used to adjust the operation frequency of the compressor, so as to slow down the heating speed of the air conditioning equipment.
In one example, a control method of the air conditioning apparatus according to the present embodiment will be described in detail with reference to fig. 2:
When the second deviation value Δt2∈ (++2), the first deviation value Δt1∈ [0,2], the reference outlet air temperature information T 4 exceeds the desired warm or cool requirement of the user, but the reference indoor temperature information T 3 is close to the set indoor temperature information T 1 set by the user, the indoor temperature environment is close to the comfortable temperature environment required by the user, and the existing output frequency of the compressor is still maintained in order to maintain the indoor comfortable environment.
When the second deviation value Δt2∈ (++2), the first deviation value Δt1∈ [2,4], the indoor temperature environment does not reach the comfortable temperature environment required by the user, but the reference air outlet temperature information T 4 exceeds the warm or cool requirement of the user, the heating or cooling speed needs to be slowed down, and at this time, the first correction frequency f=f0-1 of the compressor. Wherein F0 is the operating frequency at the current moment in the operation process of the compressor.
When the second deviation value DeltaT2 epsilon (infinity, -2) and the first deviation value DeltaT1 epsilon (4, infinity) are not enough to reach the comfortable temperature environment required by the user, the compressor can automatically adjust to the maximum frequency to work at the moment, and the reference air outlet temperature information T 4 exceeds the warm or cool requirement of the user, thereby meeting the requirement of the user on local rapid cooling and heating, and therefore, the frequency of the compressor is not required to be adjusted, the existing output frequency of the compressor is kept, and the indoor temperature environment reaches the comfortable temperature environment required by the user as soon as possible.
When the second deviation value delta T2 epsilon [ -2,2] is close to the target air outlet temperature information T 2 set by the user by referring to the air outlet temperature information T 4, the existing output frequency of the compressor is kept without adjusting the frequency of the compressor.
When the second deviation value Δt2 e (2, 5) and the first deviation value Δt1 e [0,2], the indoor temperature environment is close to the comfortable temperature environment required by the user, but the reference air outlet temperature information T 4 at the air outlet does not reach the warm or cool requirement of the user, but the difference is not large, so that the existing output frequency of the compressor is still maintained for maintaining the indoor comfortable environment, and no adjustment is needed.
When the second deviation value Δt2 e (2, 5) and the first deviation value Δt1 e [2,4] are not reached, the indoor temperature environment does not reach the comfortable temperature environment required by the user, and the reference air outlet temperature information T 4 and the target air outlet temperature information T 2 set by the user do not reach the warm or cool requirement of the user, at this time, in order to quickly meet the requirement of the user, the heating or cooling speed needs to be increased, at this time, the first correction frequency f=f0+1 of the compressor increases the operation frequency of the compressor.
When the second deviation value Δt2 e (2, 5) and the first deviation value Δt1 e (4, ++) are not reached, the compressor can automatically adjust to the maximum frequency to work because the indoor temperature environment is far less than the comfortable temperature environment required by the user, although the reference air-out temperature information T 4 and the target air-out temperature information T 2 set by the user are not reached to the warm or cool requirement of the user, the output frequency of the compressor cannot be increased any more, the existing output frequency of the compressor is kept, and the indoor temperature environment is enabled to reach the comfortable temperature environment required by the user as soon as possible.
When the second deviation value Δt2∈ (5, 8) and the first deviation value Δt1∈ [0,2], the indoor temperature environment is close to the comfortable temperature environment required by the user, but the reference air outlet temperature information T 4 and the target air outlet temperature information T 2 set by the user do not reach the warm or cool requirement of the user, and the difference is larger, at this time, in order to quickly meet the requirement of the user, the heating or cooling speed needs to be accelerated, at this time, the first correction frequency f=f0+2 of the compressor increases the operation frequency of the compressor.
When the second deviation value Δt2 e (5, 8) and the first deviation value Δt1 e [2,4], the indoor temperature environment does not reach the comfortable temperature environment required by the user, and the reference air outlet temperature information T 4 and the target air outlet temperature information T 2 set by the user do not reach the warm or cool requirement of the user, and the difference is larger, at this time, in order to quickly meet the requirement of the user, the heating or cooling speed needs to be accelerated, at this time, the first correction frequency f=f0+5 of the compressor increases the running frequency of the compressor.
When the second deviation value Δt2∈ (5, 8) and the first deviation value Δt1∈ (4, ++), the indoor temperature environment is far less than the comfortable temperature environment required by the user, the compressor can automatically adjust to the maximum frequency to work, although the reference air-out temperature information T 4 and the target air-out temperature information T 2 set by the user do not meet the warm or cool requirement of the user, the output frequency of the compressor can not be increased any more, so that the existing output frequency of the compressor is maintained, and the indoor temperature environment can reach the comfortable temperature environment required by the user as soon as possible.
Here, it should be noted that the numerical values shown in fig. 2 of this example are merely illustrative of an explanation method, and in the actual application process, the numerical values may be set according to actual requirements.
In step S400, based on the first correction frequency F of the compressor, the operation frequency of the compressor is adjusted, so that the reference indoor temperature information T 3 and the reference air-out temperature information T 4 reach the set indoor temperature information T 1 and the target air-out temperature information T 2 as soon as possible, thereby meeting the requirements of users and improving the use experience of the users.

In step S101, the set air outlet temperature information may be a gear set by the user through an input device of the air conditioning apparatus, for example, a first gear, a second gear … … displayed by text information, or gear information adjusted by "+", "-" symbols, or a specific air outlet temperature value, and after the user sets the set air outlet temperature information through the input device of the air conditioning apparatus, the input device transmits the set air outlet temperature information to the air conditioning apparatus through bluetooth, infrared transmission, wiFi, ultra wideband technology, and the like, and the air conditioning apparatus acquires the set air outlet temperature information.
In step S102, the preset modes may include a cooling mode and a heating mode to satisfy cooling and heating requirements of a user. The air outlet temperature deviation refers to the difference between the reference indoor temperature information T 3 and the air outlet temperature information, and under different preset modes, the air outlet temperature deviation obtained by different set air outlet temperature information is different.
In some possible embodiments, in step S102, obtaining the outlet air temperature deviation at least according to the set outlet air temperature information includes:
s1021, selecting refrigeration configuration information or heating configuration information according to a preset mode;
and S1022, obtaining the air outlet temperature deviation according to the set air outlet temperature information based on the refrigeration configuration information or the heating configuration information, wherein the refrigeration configuration information or the heating configuration information is used for representing the corresponding relation between the set air outlet temperature information and the air outlet temperature deviation.
In this embodiment, the manner of obtaining the deviation of the outlet air temperature will be described by setting the outlet air temperature information of the first gear, the second gear … …, which are displayed in text information, or the gear information adjusted in "+", "-" symbols, which are set by the user through the input device of the air conditioning apparatus.
In step S1021, when the user selects the preset mode as the cooling mode, cooling configuration information is selected, and when the user selects the preset mode as the heating mode, heating configuration information is selected. The cooling configuration information and the heating configuration information may be set in the air conditioning apparatus when the air conditioning apparatus leaves the factory, or may be stored in the cloud server, and may be retrieved from the cloud server to the air conditioning apparatus for execution when the cooling configuration information and the heating configuration information need to be used.
In step S1022, the cooling configuration information or the heating configuration information may be set in the air conditioning apparatus when the air conditioning apparatus leaves the factory, or may be stored in the cloud server, and may be retrieved from the cloud server to the air conditioning apparatus to be executed when the cooling configuration information or the heating configuration information needs to be used. The refrigeration configuration information or the heating configuration information are used for representing the corresponding relation between the air outlet temperature information and the air outlet temperature deviation, that is, when different air outlet temperature information is set by a user in different preset modes, the air outlet temperature information can be directly compared with each gear stored in the corresponding refrigeration configuration information or heating configuration information, so that the corresponding air outlet temperature deviation is obtained.
Because the comfortable temperature of the environment of the human body is between 22 and 25 ℃, the distance between the comfortable temperature and the hot air temperature in summer is shorter, and the distance between the comfortable temperature and the hot air temperature in summer is longer, different configuration information is arranged for different preset modes, and the deviation of the temperature of the air outlet is also different under the same gear. Illustratively, fig. 3 shows refrigeration configuration information. When the user selects the preset mode as the cooling mode, as shown in fig. 3, different air outlet temperature deviations are obtained according to different gear positions of the set air outlet temperature information set by the user. When the difference between the air outlet temperature at the air outlet required by a user and the reference indoor temperature information T 4 is not large, a first gear can be selected, and the corresponding air outlet temperature deviation is 7 ℃; when the difference between the air outlet temperature required by the user and the reference indoor temperature information T 4 is large, a second gear can be selected, and the corresponding air outlet temperature deviation is 10 ℃; when the difference between the air outlet temperature required by the user and the reference indoor temperature information T 4 is very large, a third gear can be selected, and the corresponding air outlet temperature deviation is 13 ℃. For example, when the reference indoor temperature information T 4 is 27 ℃, the indoor is comfortable and cool, and the first gear can be selected; when the reference indoor temperature information T 4 is 31 ℃, the indoor is hot, and a second gear can be selected; when the reference indoor temperature information T 4 is 36 ℃, the indoor temperature is very hot, and a third gear can be selected; to obtain a relatively comfortable outlet air temperature.
For example, fig. 4 shows heating configuration information, and when a user selects a preset mode as the heating mode, as shown in fig. 4, different outlet air temperature deviations are obtained according to different gear positions of the set outlet air temperature information set by the user. When the difference between the air outlet temperature required by the user and the reference indoor temperature information T 4 is not large, a first gear can be selected, and the corresponding air outlet temperature deviation is 13 ℃; when the difference between the air outlet temperature required by the user and the reference indoor temperature information T 4 is large, a second gear can be selected, and the corresponding air outlet temperature deviation is 16 ℃; when the difference between the air outlet temperature required by the user and the reference indoor temperature information T 4 is very large, a third gear can be selected, and the corresponding air outlet temperature deviation is 19 ℃. For example, when the room temperature information T 4 is 12 ℃, the room is slightly cold, and the first gear may be selected; when the reference indoor temperature information T 4 is 8 ℃, the indoor is colder, and a second gear can be selected; when the reference indoor temperature information T 4 is 5 ℃, the indoor temperature is very cold, and a third gear can be selected; to obtain a relatively comfortable outlet air temperature.
It will be appreciated that the gear positions in the cooling configuration information and the heating configuration information and the corresponding air outlet temperature deviations are only exemplary, and that a plurality of gear positions may be set to correspond to a plurality of air outlet temperature deviations so as to meet the requirements of users, which is not limited in this disclosure.
In some possible embodiments, in step S102, obtaining the outlet air temperature deviation at least according to the set outlet air temperature information includes:
S1023, taking the difference value between the set air outlet temperature information and the reference indoor temperature information as the air outlet temperature deviation.
In this embodiment, the air outlet temperature information is set to a specific air outlet temperature value set by the user through the input device of the air conditioning device, and therefore, the difference between the set air outlet temperature information and the reference indoor temperature information is taken as the air outlet temperature deviation.
In step S103, under different preset modes, the target air-out temperature information T 2 is calculated according to the reference indoor temperature information T 4 and the air-out temperature deviation, so that the user obtains a relatively comfortable air-out temperature.
In an exemplary embodiment, when the preset mode is the cooling mode, the air outlet temperature deviation includes a cooling air outlet deviation, and in step S103, obtaining the target air outlet temperature information based on the preset mode, the reference indoor temperature information, and the air outlet temperature deviation includes:
s1031, calculating the product of a wind gear correction coefficient and a refrigerating wind outlet deviation;
S1032, taking the difference value of the product of the reference indoor temperature information, the wind shield correction coefficient and the refrigerating air-out deviation as a first parameter;
s1033, obtaining anti-condensation parameters according to the reference indoor temperature information and the environment relative humidity information;
S1034, selecting the maximum temperature value between the first parameter and the anti-condensation parameter as target air outlet temperature information.
In step S1031, fig. 5 shows a correspondence relationship between the wind level correction coefficient and the wind level. The wind gear correction coefficient α is a coefficient for compensating for a deviation of cooling air output according to different operation gears of an internal circulation fan in the air conditioning apparatus, and referring to fig. 5, the internal circulation fan of the air conditioning apparatus may self-adjust the operation gears according to a set temperature, and different wind gears are provided with wind gear correction coefficients α corresponding thereto. The corresponding configuration relation of the wind shield and the wind shield correction coefficient alpha can be set in the air conditioning equipment when the air conditioning equipment leaves the factory, can be stored in the cloud server, and can be called from the cloud server to the air conditioning equipment for execution when the corresponding configuration relation of the wind shield and the wind shield correction coefficient alpha is needed to be used.
In this embodiment, a wind shield correction coefficient α is obtained according to a current wind shield, and the obtained wind shield temperature deviation is used as a cooling wind-out deviation Tc according to the cooling configuration information and the set wind-out temperature information set by a user, and a product of the wind shield correction coefficient and the cooling wind-out deviation Tc is calculated and used as a corrected cooling wind-out deviation α×tc.
In step S1032, a difference value of the product of the reference indoor temperature information T 3 and the air-stage correction coefficient α and the cooling air outlet deviation Tc is taken as a first parameter X, which is exemplarily expressed as:
X1＝T3–α*Tc
in step S1033, when the temperature of the air outlet of the air conditioning device is too low and the temperature difference between the air outlet and the hot air outside the air conditioning device is large, after the two hot and cold air meet, the water vapor is condensed into a small water droplet, and condensation occurs on the outer side of the air deflector and the panel of the air conditioning device. When the condensation appears, the cold loss of the air conditioning equipment is increased, the running cost is increased, the condensation possibly permeates into the air conditioning equipment, elements are corroded or short-circuited, the service life of the air conditioning equipment is reduced, potential safety hazards are possibly generated, in addition, the condensation also can damage ceilings and furniture of indoor spaces of users, and the long-term humidity easily causes the exceeding standard of indoor mould to harm the physical health of the users. The condensation phenomenon is related to the reference indoor temperature information T 3 and the environmental relative humidity information U, and thus, the anti-condensation parameter Y1 is obtained as a lower limit value of the outlet air temperature according to the reference indoor temperature information T3 and the environmental relative humidity information U.
Illustratively, a method for calculating the anti-condensation parameter Y1 includes:
Y1＝-28+0.7*T3+61.2194*U+0.0005*T3 2 -32.8593*U2+0.3250*T3*U
In step S1034, since the anti-condensation parameter Y1 is used as the lower limit value of the air outlet temperature, if the first parameter X1 is higher than the anti-condensation parameter Y1, the air outlet temperature set by the user makes the air conditioning equipment not generate condensation, and the first parameter X1 is selected as the target air outlet temperature information T 2; if the first parameter X1 is lower than the anti-condensation parameter Y1, the set air outlet temperature set by the user enables condensation to occur in the air conditioning equipment, the anti-condensation parameter Y1 is selected as target air outlet temperature information T 2, the air outlet temperature is reduced as much as possible, the air conditioning equipment is prevented from being condensed, and the increase of the operation cost and the potential safety hazard are avoided. Illustratively, in the cooling mode, the target outlet air temperature information T 2 is represented as:
T2＝max(X1，Y1)
X1＝T3–α*Tc,Y1＝-28+0.7*T3+61.2194*U+0.0005*T3 2 -32.8593*U2+0.3250*T3*U
Wherein T 3 is reference indoor temperature information, alpha is a wind shield correction coefficient, tc is refrigeration air outlet temperature difference, and U is environment relative humidity information. That is, in the cooling mode, the target outlet air temperature information T 2 selects the maximum value between the first parameter X1 and the condensation preventing parameter Y1.
In an exemplary embodiment, when the preset mode is a heating mode, the air outlet temperature deviation includes a heating air outlet deviation, and in step S103, obtaining the target air outlet temperature information based on the preset mode, the reference indoor temperature information, and the air outlet temperature deviation includes:
s1035, calculating the product of the wind gear correction coefficient and the heating air outlet deviation;
S1036, taking the sum of products of the reference indoor temperature information, the wind shield correction coefficient and the heating air outlet deviation as a second parameter;

s1038, selecting the minimum temperature value between the second parameter and the load protection temperature information as target air outlet temperature information.
In step S1035, the wind gear correction coefficient α is the same as that in step S1031, and will not be described here. And obtaining a wind shield correction coefficient alpha according to the current wind shield, taking the obtained wind shield temperature deviation as a heating wind outlet deviation Th according to heating configuration information and set wind outlet temperature information set by a user, and calculating the product of the wind shield correction coefficient and the heating wind outlet deviation Th to be used as the corrected heating wind outlet deviation alpha x Th.
In step S1036, the sum of the reference indoor temperature information T 3 and the product of the damper correction coefficient α and the heating outlet air deviation Th is taken as the second parameter X2, and the second parameter X2 is expressed as:
X2＝T3+α*Th
In step S1037, when the outlet air temperature set by the user is too high, in order to increase the outlet air temperature of the air conditioning apparatus, the compressor may be operated at a relatively high output frequency, and long-time high-frequency operation of the compressor may cause overload operation of the compressor, thereby creating a safety hazard. The overload protection temperature information Y2 is related to heating overload limiting the compressor frequency, and the overload protection temperature information Y2 is set to 51 ℃ as an upper limit value of the outlet air temperature, for example.
In step S1038, since the overload protection temperature information Y2 is used as the upper limit value of the air outlet temperature, if the second parameter X2 is lower than the overload protection temperature information Y2, the set air outlet temperature set by the user will not make the compressor of the air conditioning apparatus operate in overload, and the second parameter X2 is selected as the target air outlet temperature information T 2; if the second parameter X2 is higher than the overload protection temperature information Y2, the set air outlet temperature set by the user enables the compressor to operate in an overload mode, the overload protection temperature information Y2 is selected as target air outlet temperature information T 2, the air outlet temperature is raised as much as possible, overload heating of the compressor is prevented, and potential safety hazards are avoided. Illustratively, in the heating mode, the target outlet air temperature information T 2 is represented as:
T2＝min(X2，Y2)
X2＝T3+α*Th，Y2＝51℃
Wherein T 3 is reference indoor temperature information, alpha is a wind shield correction coefficient, th is heating air outlet temperature difference, and Y2 is overload protection temperature information. Namely, in the heating mode, the target outlet air temperature information T 2 selects the smallest value between the second parameter X2 and the load protection temperature information Y2.

For example, the indoor temperature information T 1 is set to 26 ℃, the preset time period is 3 minutes, the reference indoor temperature information T 3 obtained for the first time is set to 32 ℃, and the indoor temperature difference is set to 6 ℃; the reference indoor temperature information T 3 obtained for the second time is 31 ℃, the indoor temperature difference is 5 ℃, and the indoor temperature change rate is 33.33%; the third time of obtaining the reference indoor temperature information T 3 is 29 ℃, the indoor temperature difference is 3 ℃, the indoor temperature change rate is 66.66%, the fourth time of obtaining the reference indoor temperature information T 3 is 28 ℃, the indoor temperature difference is 2 ℃, the indoor temperature change rate is 33.33%, and so on.
In step S600, the larger the indoor temperature difference is, the larger the reference indoor temperature information T 3 is and the set indoor temperature information T 1 is, the larger the difference between the indoor environment temperature at the present moment and the indoor environment temperature required by the user is, the second correction frequency of the compressor needs to be adjusted, and the refrigerating or heating speed of the air conditioning apparatus is increased. The greater the indoor temperature change rate, the faster the reference indoor temperature information T 3 is changed, and the greater the operation frequency of the compressor at the present time. And combining the indoor environment temperature and the indoor temperature change rate to obtain a second correction frequency of the compressor.
In step S700, the operation frequency of the compressor is adjusted based on the second correction frequency of the compressor, so that the reference indoor temperature information T 3 reaches the set indoor temperature information T 1 as soon as possible, thereby meeting the requirements of the user and improving the use experience of the user.
In some possible embodiments, the control method of the air conditioning apparatus provided by the present disclosure may be adjusted at different times using the first correction frequency of the compressor or the second correction frequency of the compressor. For example, when the user wants to adjust the air outlet temperature only, the compressor operating frequency is adjusted only by the first correction frequency F of the compressor, or the user does not adjust the temperature of the air outlet, and when the indoor temperature information T 1 is set, the compressor operating frequency is adjusted only by the second correction frequency of the compressor, or the user sets the set indoor temperature information T 1 and the set air outlet temperature information at the same time, and the first correction frequency of the compressor and the second correction frequency of the compressor are adjusted by a certain setting stagger, for example, the first correction frequency of the compressor is used at 2 nd, 4 th and 6 th minutes, and the second correction frequency of the compressor is used at 3 rd, 5 th and 7 th minutes.
