In the air conditioner 100, the refrigeration system 110 may also be provided with a reversing valve to change the flow direction of the refrigerant, so that the indoor unit heat exchanger alternately acts as an evaporator or a condenser to achieve cooling or heating functions. Since the compression refrigeration cycle in the air conditioner 100 is well known to those skilled in the art, its working principle and structure will not be repeated here. In this embodiment, an inverter compressor is used as the compressor 111 .

In this embodiment, the first temperature sensor 130 is configured to detect the outdoor ambient temperature of the air conditioner 100 . The controller 120 is configured to obtain the turn-on time of the air conditioner 100, determine the pre-operation time of the air conditioner 100 according to the outdoor ambient temperature of the air conditioner 100 detected by the first temperature sensor 130, and turn on the compressor 111 before the above turn-on time, so as to compress the air conditioner 100. The air conditioner 111 operates at the pre-operation frequency, so that the air conditioner 100 enters the pre-operation state, and when the above-mentioned activation time is reached, the air conditioner 100 is turned on and enters the normal operation state. The time difference between the time when the compressor 111 is turned on and the time when the compressor 111 is turned on is the pre-operation time determined according to the outdoor ambient temperature.

The above-mentioned start-up time of the air conditioner 100 may be the start-up time set by the user or the start-up time calculated according to the historical start-up time in the start-up record of the air conditioner 100 . The air conditioner 100 can store the operation time of the air conditioner 100 by the user every day, and extract the time when the user turns on the air conditioner 100 every day from the operation time. as the beginning of history. Using a statistical analysis method, the current ON time of the air conditioner 100 is calculated according to the historical ON time of the air conditioner 100 .

The controller 120 may also be configured to obtain a model of the start-up time of the air conditioner 100, the model of the start-up time of the air conditioner 100 is pre-established according to the historical start-up time of the air conditioner 100 and the historical environmental parameters of the air conditioner 100, and the environmental parameters of the air conditioner 100 are input. The start-up time model of the air conditioner 100 is used to obtain the start-up time of the air conditioner 100 .

The historical environmental parameters of the air conditioner 100 are recorded in the historical environmental parameter record, which may include indoor temperature, outdoor temperature, and the like. The establishment of the power-on time model of the air conditioner 100 may specifically be: establishing a classification model with the historical power-on time and historical environmental parameters corresponding to the historical power-on time as characteristic data, obtaining the corresponding relationship between the environmental parameters and the power-on time, and then using the detected environment. The parameters are input into the model, and the corresponding start time of the air conditioner 100 under the environmental parameters can be output. Through the method of big data statistical analysis, the obtained turn-on time of the air conditioner 100 can accurately reflect the user's turning-on habit, and the subsequent turn-on time of the air conditioner 100 is determined according to the user's turning-on habit, thereby providing an accurate reference for the pre-operation of the air conditioner 100 , so that the operation of the air conditioner 100 can better match the needs of users.

In order to determine the pre-operation time of the air conditioner 100 and accurately control the pre-operation of the air conditioner 100, the controller 120 is further configured to obtain a calculation and fitting formula for the pre-operation time of the air conditioner 100, and input the outdoor ambient temperature into the calculation and fitting formula. By calculation, the pre-operation time of the air conditioner 100 is obtained. The calculation and fitting formula expresses the corresponding relationship between the outdoor ambient temperature and the pre-operation time of the air conditioner 100 . The calculation fitting formula can be obtained by fitting the experimental data. For example, multiple experiments were performed on the pre-operation of compressor 111 for different outdoor ambient temperatures. In several experiments, the air conditioner outlet air temperature when the air conditioner 100 enters the normal operation state is set to the same target temperature, and the compressor 111 is operated at the same pre-operation frequency to determine the air conditioner outlet air temperature under different outdoor ambient temperatures. To reach the target temperature, the compressor 111 needs a pre-run time, so as to establish a linear relationship between the pre-run time of the compressor 111 and the outdoor ambient temperature.

The air conditioner 100 may further include a second temperature sensor 140 configured to detect the indoor ambient temperature of the air conditioner 100 . In order to precisely control the pre-operation of the compressor 111, the controller 120 is further configured to obtain the indoor ambient temperature of the air conditioner 100, and calculate the pre-operation frequency of the compressor 111 according to the indoor ambient temperature and the outdoor ambient temperature. The compressor 111 of the air conditioner 100 is turned on before the start time of the air conditioner 100, so that the compressor 111 operates at the pre-operation frequency calculated above. , control the indoor unit fan 112 to work, adjust the position of the air deflector, and turn on the air conditioner 100 to enter the normal operation state.

The controller 120 may also be configured to acquire operating parameters, operating modes, and operating records of the air conditioner 100, and make the air conditioner 100 operate with the acquired operating parameters and operating modes when the air conditioner 100 enters a normal operating state. The operating parameters and operating modes include the operating parameters and operating modes of the air conditioner 100 set by the user, or the operating parameters and operating modes obtained according to historical operating records in the operating records of the air conditioner 100 . The operating parameters may include the operating temperature of the air conditioner 100, the rotational speed of the fan, the position of the air deflector, etc., and the operating modes may include a cooling mode and a heating mode.

The controller 120 can also be configured to output a prompt message that the air conditioner 100 is turned on to the user terminal pre-bound with the air conditioner 100 before turning on the air conditioner 100 to enter the normal operation state, so as to confirm to the user whether to turn on the air conditioner 100 . After the air conditioner 100 is turned on, the turn-on time of the air conditioner 100 is recorded in the turn-on record table, so as to provide data reference for the subsequent determination of the turn-on time of the air conditioner 100 .

The control process of the air conditioner 100 in the above embodiment will be further described below with reference to the control method for the air conditioner 100 in this embodiment. The control method for the air conditioner 100 in this embodiment can be executed by the controller 120 described above. The compressor 111 pre-runs for a certain period of time before turning on the air conditioner 100, so that the air conditioner 100 has sufficient outlet air temperature and heating and cooling capacity when it is turned on, so that the indoor temperature can be quickly adjusted to a comfortable temperature for the user, thereby improving the user's comfort. Heating and cooling experience.

FIG. 2 is a schematic diagram of a control method of the air conditioner 100 according to an embodiment of the present invention. The control method may generally include:

In step S202, the starting time of the air conditioner 100 is obtained.

The turn-on time of the air conditioner 100 may be the turn-on time set by the user or the turn-on time calculated according to the historical turn-on time in the start-up record of the air conditioner 100 . The air conditioner 100 can store the operation time of the air conditioner 100 by the user every day, and extract the time when the user turns on the air conditioner 100 every day from the operation time. as the beginning of history. Using a statistical analysis method, the current ON time of the air conditioner 100 is calculated according to the historical ON time of the air conditioner 100 .

Step S204, the outdoor ambient temperature of the air conditioner 100 is detected.

Step S206: Determine the pre-operation time of the air conditioner 100 according to the outdoor ambient temperature, and turn on the compressor 111 of the air conditioner 100 before the start time, so that the compressor 111 operates at the pre-operation frequency, so that the air conditioner 100 enters the pre-operation state.

The time difference between the time when the compressor 111 of the air conditioner 100 is turned on and the time when the compressor 111 is turned on is the pre-operation time. That is, the pre-operation time of the air conditioner 100 is first determined according to the outdoor ambient temperature, and the pre-operation time of the air conditioner 100 is pushed forward to determine the start time of the compressor 111 .

The air conditioner 100 enters the pre-operation state, the refrigeration system 110 operates, the indoor unit fan 112 of the air conditioner 100 does not work, and the refrigerant circulates between the condenser and the evaporator to adjust the temperature of the evaporator to an appropriate value.

Step S208, when the turn-on time is reached, turn on the air conditioner 100 and enter the normal operation state.

After the compressor 111 is turned on for the above-mentioned pre-running time, the turn-on time is reached, then the air conditioner 100 is turned on, the indoor unit fan 112 works, and the position of the air deflector is adjusted, so that the air conditioner 100 enters the normal operation state. Since the temperature of the evaporator has been adjusted to an appropriate temperature, after the air conditioner 100 enters the normal operation state, the air outlet temperature and the cooling and heating capacity of the air conditioner 100 can be rapidly increased, the indoor temperature can be quickly adjusted to an appropriate temperature, and the cooling of the user can be improved. Heating experience.

The step of obtaining the start-up time according to the statistics of the historical start-up time in the start-up record of the air conditioner 100 in step S202 may specifically include: acquiring a start-up time model of the air conditioner 100, and the start-up time model of the air conditioner 100 is based on the history of the air conditioner 100. The start-up time and historical environmental parameters of the air conditioner 100 are established in advance, and the environmental parameters of the air conditioner 100 are input into the start-up time model of the air conditioner 100 to obtain the start-up time of the air conditioner 100 .

The historical environmental parameters of the air conditioner 100 are recorded in the historical environmental parameter record, which may include indoor temperature, outdoor temperature, and the like. The establishment of the power-on time model of the air conditioner 100 may specifically be: establishing a classification model with the historical power-on time and historical environmental parameters corresponding to the historical power-on time as characteristic data, obtaining the corresponding relationship between the environmental parameters and the power-on time, and then using the detected environment. The parameters are input into the model, and the corresponding start time of the air conditioner 100 under the environmental parameters can be output. Through the method of big data statistical analysis, the obtained turn-on time of the air conditioner 100 can accurately reflect the user's turning-on habit, and the subsequent turn-on time of the air conditioner 100 is determined according to the user's turning-on habit, thereby providing an accurate reference for the pre-operation of the air conditioner 100 , so that the operation of the air conditioner 100 can better match the needs of users.

The step of determining the pre-operation time of the air conditioner 100 according to the outdoor ambient temperature in step S206 may specifically include: obtaining a calculation and fitting formula for the pre-operation time of the air conditioner 100, inputting the outdoor ambient temperature into the calculation and fitting formula for calculation, and obtaining the air conditioner 100 pre-run time.

The calculation and fitting formula expresses the corresponding relationship between the outdoor ambient temperature and the pre-operation time of the air conditioner 100 . The calculation fitting formula can be obtained by fitting the experimental data. For example, several experiments are performed on the pre-operation of the compressor 111 for different outdoor ambient temperatures. Running at the same pre-running frequency, it is determined that under different outdoor ambient temperatures, the air conditioner outlet temperature reaches the target temperature and the compressor 111 needs pre-run time, thereby establishing a linear relationship between the compressor 111 pre-run time and the outdoor ambient temperature. The calculation and fitting formula thus determined may be: ΔT=a×Tao+b, where ΔT is the pre-operation time of the air conditioner 100 , Tao is the outdoor ambient temperature, and a and b are preset constants. a and b are obtained by the linear fitting of the above experimental data. Taking the heating operation of the air conditioner 100 as an example, the a and b obtained by the linear fitting in the above experiment can be -0.5 and 15 respectively. Taking the operation as an example, the a and b obtained by the linear fitting of the above experiment can be 0.375 and 5, respectively.

For the heating and cooling operation of the air conditioner 100, the pre-operation time ΔT of the air conditioner 100 needs to be limited to a certain value range. For example, when the air conditioner 100 is in heating operation, the value range of the pre-operation time ΔT can be: 5 minutes≤ΔT ≤35 minutes. That is, if the pre-operation time ΔT obtained by the above calculation and fitting formula is greater than 35 minutes, it means that the outdoor ambient temperature is too low at this time, which is an extremely cold environment, and the pre-operation time ΔT of the air conditioner 100 is taken as 35 minutes. If the pre-running time ΔT obtained by the above calculation and fitting formula is less than 5 minutes, it means that the outdoor environment is relatively high at this time, and pre-cooling is not required for too long, and the pre-run time ΔT is taken as 5 minutes. For example, when the air conditioner 100 is in cooling operation, the value range of the pre-operation time ΔT may be: 1 minute≤ΔT≤10 minutes, that is, if the pre-operation time ΔT is greater than 10 minutes through the above calculation and fitting formula, it means that at this time The outdoor ambient temperature is too high, which is an extremely hot environment, and the pre-operation time ΔT of the air conditioner 100 is taken as 10 minutes. If the pre-running time ΔT obtained by the above calculation and fitting formula is less than 1 minute, it means that the outdoor environment is relatively high at this time, and pre-cooling is basically unnecessary, and the pre-running time ΔT is taken as 1 minute.

In the pre-operation time ΔT of the air conditioner 100, the air conditioner 100 is in the pre-operation state, the compressor 111 in the outdoor unit works, and the indoor unit does not work, the pressure on the high-pressure side can be rapidly increased, so that the air conditioner 100 can obtain sufficient Pressure drives the flow of refrigerant. Once the pre-running time of the air conditioner 100 is completed ΔT, that is, the start time of the air conditioner 100 is reached, the user will be intelligently turned on, and the position of the indoor unit fan 112 and the air deflector will be turned on, so that the air conditioner 100 will enter the normal operation state. The user can also adjust the operating parameters of the air conditioner 100 according to their own needs.

In order to precisely control the pre-operation of the air conditioner 100, before the step of turning on the compressor 111 of the air conditioner 100, it may further include: acquiring the indoor ambient temperature of the air conditioner 100, and calculating the pre-operation of the compressor 111 according to the indoor ambient temperature and the outdoor ambient temperature. operating frequency. Specifically, the calculation formula of the pre-operation frequency of the compressor 111 may be: F=m×(Ti-Tao)+n; where F is the pre-operation frequency of the compressor 111, Ti is the indoor ambient temperature, and Tao is the outdoor ambient temperature , m and n are preset constants.

The above calculation formula can be fitted according to the experimental data. For example, a number of experiments were performed on the pre-operation of the air conditioner 100 under different outdoor ambient temperatures and indoor ambient temperatures. In several experiments, the air-conditioning outlet air temperature when the air conditioner 100 enters the normal operation state is set to the same target temperature, and the compressor 111 runs for the same pre-run time, and it is judged that under different outdoor ambient temperatures and different indoor ambient temperatures , the air-conditioning outlet air temperature reaches the target temperature, and the pre-operation frequency required by the compressor 111 is established, thereby establishing a linear relationship between the pre-operation frequency of the compressor 111 and the outdoor ambient temperature and the indoor ambient temperature.

The above m and n are obtained by linear fitting of the above experimental data. Taking the heating operation of the air conditioner 100 as an example, the above experiments are performed to obtain m and n obtained by linear fitting, which can be 2.5 and 50, respectively. Taking the operation as an example to carry out the above experiment, the m and n obtained by linear fitting can be -1.5 and 40, respectively.

For the heating and cooling operation of the air conditioner 100, the pre-operation frequency F of the air conditioner 100 needs to be limited to a certain value range. That is, if the pre-operation frequency F obtained by the above calculation and fitting formula is greater than 75 Hz, the pre-operation frequency F of the air conditioner 100 is taken as 75 Hz. When the air conditioner 100 is in cooling operation, the value range of the pre-operation frequency F can be: F≤55HZ, that is, if the pre-operation frequency F obtained by the above calculation and fitting formula is greater than 55HZ, take the pre-operation frequency F of the air conditioner 100 is 55HZ.

If the pre-operation time of the compressor 111 is too short, when the air conditioner 100 is turned on and enters normal operation, the air outlet temperature and the cooling and heating capacity of the air conditioner 100 change slowly, which affects the user's cooling and heating experience. On the other hand, if the pre-run time of the compressor 111 is too long, the pressure of the air conditioner 100 will be too high, which will cause power consumption and poor cooling and heating effect. In the control method of the air conditioner 100 in this embodiment, the pre-operation frequency of the compressor 111 is calculated according to the indoor ambient temperature and the outdoor ambient temperature, so that the outlet air temperature and the cooling and heating capacity of the air conditioner 100 can be increased in time when the air conditioner 100 is turned on for normal operation. , the pre-operation time of the compressor 111 of the air conditioner 100 can be accurately determined, and the problem caused by the pre-operation time of the air conditioner 100 being too short or too long can be avoided.

Before the step of turning on the air conditioner 100 to enter the normal operation state, it may further include: outputting a prompt message that the air conditioner 100 is turned on to the user terminal pre-bound with the air conditioner 100 to confirm to the user whether to turn on the air conditioner 100 . If the user still does not give confirmation feedback when reaching the turn-on time of the air conditioner 100, the air conditioner 100 can be turned on by itself, and the turn-on time is recorded in the turn-on record table, so as to provide data reference for the subsequent determination of the turn-on time of the air conditioner 100 . If the user feedback that the air conditioner 100 is not turned on, the operation of the compressor is stopped.

Before turning on the compressor 111 of the air conditioner 100 to run at the pre-operation frequency, it may also include: outputting a prompt message that the air conditioner 100 performs pre-operation to the user terminal pre-bound with the air conditioner 100, if the user arrives at the air conditioner 100 There is no confirmation feedback when the compressor 111 pre-runs start time. Once the compressor 111 pre-run start time is reached, the compressor 111 is turned on to run at the pre-run frequency, so that the air conditioner 100 enters the pre-run state. If the user gives feedback that the compressor 111 of the air conditioner 100 is not turned on before the time when the compressor 111 of the air conditioner 100 is turned on, the air conditioner 100 does not perform subsequent operations. By combining the pre-operation and intelligent start of the air conditioner 100 with the user's feedback, the pre-operation of the air conditioner 100 and the intelligent start of the air conditioner 100 can be flexibly adjusted according to the actual situation of the user, thereby improving the user experience.

After the step of acquiring the ON time of the air conditioner 100, the method may further include: acquiring the operating parameters and operating mode of the air conditioner 100, and when the air conditioner 100 enters the normal operating state, making the air conditioner 100 use the acquired operating parameters and operating mode run. Wherein, the step of acquiring the operating parameters and operating modes of the air conditioner 100 may include: acquiring the operating parameters and operating modes of the air conditioner 100 set by the user, or acquiring the operating records of the air conditioner 100, and according to the historical operating records in the operating records Statistics get the operating parameters and operating modes. The operating parameters may include the operating temperature of the air conditioner 100, the rotational speed of the fan, the position of the air deflector, etc., and the operating modes may include a cooling mode and a heating mode.

The control method of the air conditioner 100 in this embodiment may be aimed at the cooling or heating conditions of the air conditioner 100. FIG. 3 is a flowchart of the control method of the air conditioner 100 according to an embodiment of the present invention, and the control process includes:
