In the air conditioner 100, the refrigeration system 110 may further include a reversing valve to change the flow direction of the refrigerant, so that the indoor heat exchanger may alternatively serve as an evaporator or a condenser to perform a cooling or heating function. Since the compression refrigeration cycle of the air conditioner 100 is well known to those skilled in the art, the operation principle and structure thereof will not be described herein. In the present embodiment, the compressor 111 uses an inverter compressor.
In the present 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 acquire a turn-on time of the air conditioner 100, determine a pre-operation time of the air conditioner 100 according to an outdoor ambient temperature of the air conditioner 100 detected by the first temperature sensor 130, and turn on the compressor 111 before the turn-on time, so that the compressor 111 operates at a pre-operation frequency, so that the air conditioner 100 enters a pre-operation state, and turn on the air conditioner 100 to enter a normal operation state when the turn-on time is reached. The time difference between the time when the compressor 111 is turned on and the time when the compressor is turned on is the pre-operation time determined according to the outdoor ambient temperature.
The turn-on time of the air conditioner 100 may be a turn-on time set by a user or a turn-on time counted from a historical turn-on time in a turn-on record of the air conditioner 100. The air conditioner 100 may store therein an operation time of the air conditioner 100 by the user every day, and extract an on time of the air conditioner 100 by the user every day from the operation time, for example, a time when the user turns on the air conditioner 100 in any time period of morning, day, and night, as a history on time. The current turn-on time of the air conditioner 100 is calculated from the historical turn-on time of the air conditioner 100 by a statistical analysis method, for example, an average value of the historical turn-on times is calculated and is used as the current turn-on time of the air conditioner 100.
The controller 120 may be further configured to obtain a startup time model of the air conditioner 100, where the startup time model of the air conditioner 100 is pre-established according to the historical startup 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 into the startup time model of the air conditioner 100 to obtain the startup time of the air conditioner 100.
The historical environmental parameters of the air conditioner 100 are recorded in the historical environmental parameter record and may include indoor temperature, outdoor temperature, and the like. The establishment of the startup time model of the air conditioner 100 may specifically be: and establishing a classification model by taking the historical starting time and the historical environmental parameters corresponding to the historical starting time as characteristic data to obtain the corresponding relation between the environmental parameters and the starting time, and inputting the detected environmental parameters into the model so as to output the starting time of the air conditioner 100 corresponding to the environmental parameters. By the big data statistical analysis method, the obtained starting time of the air conditioner 100 can accurately reflect the starting habit of the user, and the starting time of the air conditioner 100 is determined according to the starting habit of the user, so that accurate reference is provided for the pre-operation of the air conditioner 100, and the operation of the air conditioner 100 can be matched with the requirements of the user.
In order to determine the pre-operation time of the air conditioner 100 and precisely control the pre-operation of the air conditioner 100, the controller 120 is further configured to obtain a calculation fitting formula of the pre-operation time of the air conditioner 100, and input the outdoor environment temperature into the calculation fitting formula for calculation to obtain the pre-operation time of the air conditioner 100. Wherein, the 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 according to experimental data. For example, multiple experiments are performed on the pre-operation of the compressor 111 for different outdoor ambient temperatures. In multiple experiments, the air conditioner outlet air temperature when the air conditioner 100 enters the normal operation state is set to be the same target temperature, the compressor 111 is enabled to operate at the same pre-operation frequency, the time that the air conditioner outlet air temperature reaches the target temperature and the compressor 111 needs to be pre-operated under different outdoor environment temperatures is judged, and therefore the linear relation between the pre-operation time of the compressor 111 and the outdoor environment temperature is established.
The air conditioner 100 may further include a second temperature sensor 140, the second temperature sensor 140 being configured to detect an indoor ambient temperature of the air conditioner 100. To precisely control the pre-operation of the compressor 111, the controller 120 is further configured to acquire an indoor ambient temperature of the air conditioner 100, and calculate a pre-operation frequency of the compressor 111 according to the indoor ambient temperature and the outdoor ambient temperature. And starting the compressor 111 of the air conditioner 100 before the starting time of the air conditioner 100, so that the compressor 111 operates at the calculated pre-operation frequency, the pre-operation time calculated by the calculation fitting formula reaches the starting time of the air conditioner 100, the indoor unit fan 112 is controlled to work, the position of the air deflector is adjusted, and the air conditioner 100 is started to enter a normal operation state.
The controller 120 may be further configured to acquire the operation parameters, the operation mode, and the operation record of the air conditioner 100, and to cause the air conditioner 100 to operate in the acquired operation parameters and operation mode when the air conditioner 100 enters the normal operation state. The operation parameters and the operation mode include operation parameters and an operation mode of the air conditioner 100 set by a user, or operation parameters and an operation mode statistically obtained according to a history operation record in an operation record of the air conditioner 100. The operation parameters may include an operation temperature of the air conditioner 100, a rotation speed of a fan, a position of an air guide plate, and the like, and the operation modes may include a cooling mode and a heating mode.
The controller 120 may be further configured to output a prompt message for turning on the air conditioner 100 to a user terminal pre-bound with the air conditioner 100 to confirm to a user whether to turn on the air conditioner 100 before turning on the air conditioner 100 into a normal operation state. 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 a 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 is further described below with reference to the control method of the air conditioner 100 in this embodiment, the control method of the air conditioner 100 in this embodiment may be executed by the controller 120 described above, and the air conditioner 100 is turned on after the compressor 111 is pre-operated for a certain time, so that the air conditioner 100 has sufficient air outlet temperature and heating and cooling capacity when turned on, and thus the indoor temperature can be quickly adjusted to the temperature comfortable for the user, and the heating and cooling experience of the user is improved.
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 turn-on time of the air conditioner 100 is acquired.
The turn-on time of the air conditioner 100 may be a turn-on time set by a user or a turn-on time counted from a historical turn-on time in a turn-on record of the air conditioner 100. The air conditioner 100 may store therein an operation time of the air conditioner 100 by the user every day, and extract an on time of the air conditioner 100 by the user every day from the operation time, for example, a time when the user turns on the air conditioner 100 in any time period of morning, day, and night, as a history on time. The current turn-on time of the air conditioner 100 is calculated from the historical turn-on time of the air conditioner 100 by a statistical analysis method, for example, an average value of the historical turn-on times is calculated and is used as the current turn-on time of the air conditioner 100.
In step S204, the outdoor ambient temperature of the air conditioner 100 is detected.
In step S206, a pre-operation time of the air conditioner 100 is determined according to the outdoor ambient temperature, and the compressor 111 of the air conditioner 100 is turned on before the turn-on time, so that the compressor 111 is operated at a pre-operation frequency, so that the air conditioner 100 enters a pre-operation state.
Here, the time difference between the time when the compressor 111 of the air conditioner 100 is turned on and the turn-on time is the pre-operation time. That is, the pre-operation time of the air conditioner 100 is determined according to the outdoor ambient temperature, and the start time is advanced to the time when the compressor 111 of the air conditioner 100 is turned on, thereby determining the start time of the compressor 111.
The air conditioner 100 enters a pre-operation state, the refrigeration system 110 operates, the indoor unit fan 112 of the air conditioner 100 does not operate, a refrigerant circulates between the condenser and the evaporator, and the temperature of the evaporator is adjusted to a proper value.
In step S208, when the turn-on time is reached, the air conditioner 100 is turned on to enter a normal operation state.
After the compressor 111 is started to operate for the above-mentioned pre-operation time, that is, the starting time is reached, the air conditioner 100 is started accordingly, the indoor unit fan 112 works, and the position of the air deflector is adjusted, so that the air conditioner 100 enters a normal operation state. Because the temperature of the evaporator is adjusted to be suitable temperature, after the air conditioner 100 enters a normal operation state, the air outlet temperature and the refrigerating and heating capacity of the air conditioner 100 can be rapidly increased, the indoor temperature is rapidly adjusted to be suitable temperature, and the refrigerating and heating experience of a user is improved.
The step of counting the starting time according to the historical starting time in the starting record of the air conditioner 100 in step S202 may specifically include: the starting time model of the air conditioner 100 is obtained, the starting time model of the air conditioner 100 is pre-established according to the historical starting 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 into the starting time model of the air conditioner 100 to obtain the starting time of the air conditioner 100.
The historical environmental parameters of the air conditioner 100 are recorded in the historical environmental parameter record and may include indoor temperature, outdoor temperature, and the like. The establishment of the startup time model of the air conditioner 100 may specifically be: and establishing a classification model by taking the historical starting time and the historical environmental parameters corresponding to the historical starting time as characteristic data to obtain the corresponding relation between the environmental parameters and the starting time, and inputting the detected environmental parameters into the model so as to output the starting time of the air conditioner 100 corresponding to the environmental parameters. By the big data statistical analysis method, the obtained starting time of the air conditioner 100 can accurately reflect the starting habit of the user, and the starting time of the air conditioner 100 is determined according to the starting habit of the user, so that accurate reference is provided for the pre-operation of the air conditioner 100, and the operation of the air conditioner 100 can be matched with the requirements of the user.
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: and acquiring a calculation fitting formula of the pre-operation time of the air conditioner 100, and inputting the outdoor environment temperature into the calculation fitting formula for calculation to obtain the pre-operation time of the air conditioner 100.
Wherein, the 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 according to experimental data. For example, a plurality of experiments are performed on the pre-operation of the compressor 111 according to different outdoor environment temperatures, in the plurality of experiments, the air-conditioner outlet air temperature when the air conditioner 100 enters the normal operation state is set to be the same target temperature, the compressor 111 is operated at the same pre-operation frequency, the time for which the compressor 111 needs to be pre-operated when the air-conditioner outlet air temperature reaches the target temperature under different outdoor environment temperatures is determined, and thus the linear relationship between the pre-operation time of the compressor 111 and the outdoor environment temperature is established. The calculated fit formula thus determined may be: Δ T is a × Tao + b, where Δ T is the pre-operation time of the air conditioner 100, Tao is the outdoor ambient temperature, and a and b are preset constants. a. b is obtained by linear fitting of the experimental data, a and b obtained by performing the above experiment in the case of the heating operation of the air conditioner 100 may be-0.5 and 15, respectively, and a and b obtained by performing the above experiment in the case of the cooling operation of the air conditioner 100 may be 0.375 and 5, respectively.
For the heating and cooling operation of the air conditioner 100, the pre-operation time Δ T of the air conditioner 100 needs to be limited to a certain value range, for example, when the air conditioner 100 is heating, the value range of the pre-operation time Δ T may be: delta T is more than or equal to 5 minutes and less than or equal to 35 minutes. That is, if the pre-operation time Δ T obtained by the above calculation and fitting formula is greater than 35 minutes, it indicates that the outdoor environment temperature is too low and the environment is very cold, and the pre-operation time Δ T of the air conditioner 100 is 35 minutes. If the pre-operation time delta T obtained by the calculation fitting formula is less than 5 minutes, the outdoor environment is relatively high at the moment, pre-cooling is not needed for too long time, and the pre-operation time delta T is taken as 5 minutes. For example, when the air conditioner 100 is operated in a cooling mode, the pre-operation time Δ T may be in a range of: Δ T is greater than or equal to 1 minute and less than or equal to 10 minutes, that is, if the pre-operation time Δ T obtained by the above calculation and fitting formula is greater than 10 minutes, it indicates that the outdoor environment is too hot at this time, and the pre-operation time Δ T of the air conditioner 100 is taken as 10 minutes. If the pre-operation time delta T obtained by the calculation fitting formula is less than 1 minute, the outdoor environment is relatively high at the moment, precooling is basically not needed, and the pre-operation time delta T is taken as 1 minute.
In the pre-operation time Δ T of the air conditioner 100, the air conditioner 100 is in the pre-operation state, the compressor 111 in the outdoor unit is operated, and the indoor unit is not operated, so that the pressure of the high pressure side can be rapidly increased, and the air conditioner 100 can obtain sufficient pressure to push the refrigerant to flow. Once the pre-operation time of the air conditioner 100 is finished by Δ T, that is, the starting time of the air conditioner 100 is reached, the user is intelligently powered on, and the positions of the indoor unit fan 112 and the air deflector are started, so that the air conditioner 100 enters a normal operation state. The user can also adjust the operation parameters of the air conditioner 100 according to his or her 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: the indoor ambient temperature of the air conditioner 100 is acquired, and the pre-operation frequency of the compressor 111 is calculated according to the indoor ambient temperature and the outdoor ambient temperature. Specifically, the calculation formula of the pre-operation frequency of the compressor 111 may be: f ═ mx (Ti-Tao) + n; where F is the pre-operating frequency of the compressor 111, Ti is the indoor ambient temperature, Tao is the outdoor ambient temperature, and m and n are both preset constants.
The above calculation formula can be fitted from experimental data. For example, a plurality of experiments are performed on the pre-operation of the air conditioner 100 under different outdoor ambient temperatures and indoor ambient temperatures. In multiple experiments, the air conditioner outlet air temperature when the air conditioner 100 enters the normal operation state is set to be the same target temperature, the compressor 111 is enabled to operate at the same pre-operation time, the pre-operation frequency required by the compressor 111 when the air conditioner outlet air temperature reaches the target temperature under different outdoor environment temperatures and different indoor environment temperatures is judged, and therefore the linear relation between the pre-operation frequency of the compressor 111 and the outdoor environment temperature and the indoor environment temperature is established.
The m and n are obtained by linear fitting of the experimental data, and m and n obtained by performing the linear fitting of the experiment in the case of the heating operation of the air conditioner 100 may be respectively 2.5 and 50, and m and n obtained by performing the linear fitting of the experiment in the case of the cooling operation of the air conditioner 100 may be respectively-1.5 and 40.
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, for example, when the air conditioner 100 is heating, the value range of the pre-operation frequency F may be: f is less than or equal to 75 HZ. That is, if the pre-operation frequency F is greater than 75HZ obtained by the above calculation fitting formula, the pre-operation frequency F of the air conditioner 100 is taken as 75 HZ. When the air conditioner 100 operates in a cooling mode, the pre-operation frequency F may have a value range of: f is less than or equal to 55HZ, that is, if the pre-operation frequency F obtained by the calculation fitting formula is greater than 55HZ, the pre-operation frequency F of the air conditioner 100 is taken as 55 HZ.
If the pre-operation time of the compressor 111 is too short, when the air conditioner 100 is started to enter normal operation, the change of the air outlet temperature and the cooling and heating amount of the air conditioner 100 is slow, and the cooling and heating experience of a user is affected. If the compressor 111 has too long pre-operation time, the air conditioner 100 will have too high pressure, consume power and have poor cooling and heating effects. In the control method of the air conditioner 100 of 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 are timely increased when the air conditioner 100 is started to normally operate, the time required for pre-operation of the compressor 111 of the air conditioner 100 can be accurately determined, and the problem caused by too short or too long pre-operation time of the air conditioner 100 is avoided.
Before the step of turning on the air conditioner 100 to enter the normal operation state, the method may further include: a prompt message for turning on the air conditioner 100 is output 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 does not confirm the feedback when the turn-on time of the air conditioner 100 is reached, the air conditioner 100 may turn on itself and record the turn-on time in the turn-on record table, so as to provide data reference for the following determination of the turn-on time of the air conditioner 100. If the user feedback does not turn on the air conditioner 100, the operation of the compressor is stopped.
