Referring to fig. 1, fig. 1 is a schematic view of a scene of a control method of an air conditioner according to an embodiment of the present disclosure, a control system of the air conditioner may include an indoor unit 100 and an outdoor unit 200, the indoor unit 100 is connected to the outdoor unit 200 through a pipeline, and the indoor unit 100 may receive a control signal on a remote controller or a control panel to perform a series of functions of the indoor unit of the air conditioner, such as cooling, heating, dehumidifying, and dedusting.

Those skilled in the art can understand that the application environment shown in fig. 1 is only one application scenario of the present application, and does not constitute a limitation on the application scenario of the present application, and other application environments may further include more or fewer indoor units and outdoor units than those shown in fig. 1, for example, only 1 indoor unit or outdoor unit is shown in fig. 1, and the control system of the air conditioner of the present application may further include one or more indoor units and outdoor units for executing the control method of the air conditioner of the present application, which is not limited herein.
It should be noted that the scenario diagram of the control system of the air conditioner shown in fig. 1 is only an example, the control system and the scenario of the air conditioner described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and it is known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the control system of the air conditioner and the appearance of new service scenarios.
As shown in fig. 2, fig. 2 is a flowchart illustrating an embodiment of a method for controlling an air conditioner in the embodiment of the present application, where the method for controlling an air conditioner may include the following steps 201 and 203:
201. and after the air conditioner is started, acquiring the control temperature and the indoor temperature of the air conditioner and the condensation temperature of a heat exchanger in the indoor unit.
The control temperature in this step generally refers to a temperature for controlling the operation of the air conditioner, and is usually controlled by a remote controller of the air conditioner or a control panel of an indoor unit of the air conditioner.
The indoor temperature generally refers to the average temperature of the space in which an indoor unit of an air conditioner is located, and the obtained indoor temperature can be detected by a temperature sensor arranged in the air conditioner, and the temperature sensor can obtain the indoor temperature in real time, which is not limited herein.
The condensing temperature of the heat exchanger refers to a saturation temperature of refrigerant vapor in the heat exchanger (condenser) when the refrigerant vapor condenses under a certain pressure. The condensation temperature is not equal to the temperature of the cooling medium, a heat transfer temperature difference exists between the condensation temperature and the cooling medium, the condensation pressure can be calculated generally according to the condensation temperature, and therefore the refrigeration or heating efficiency of the air conditioner can be judged laterally according to the condensation pressure.
202. And if the air conditioner operates in the heating mode, calculating the temperature difference between the control temperature and the indoor temperature.
The temperature difference between the control temperature and the indoor temperature can be calculated by a processor preset in the air conditioner, the processor is used for processing each data of the air conditioner so as to complete corresponding control, and similarly, the calculation can also be performed by installing a special calculation module, and the specific details are not limited herein.
203. And adjusting the wind speeds of the indoor unit and the outdoor unit according to the condensation temperature and the temperature difference.
According to the step 201, the condensing pressure can be obtained according to the condensing temperature, so as to reflect the cooling or heating efficiency of the air conditioner, for example, if the current set temperature is 26 degrees celsius, the air conditioner will operate according to the power that the ambient temperature is controlled at 26 degrees celsius, as the service life of the air conditioner increases, the equipment will age, the service life will increase, and the loss will occur, at this time, compared with the time of leaving the factory, the effect of condensing will decrease, so that the condensing temperature will decrease, so that the condensing pressure will decrease, so that the cooling or heating efficiency of the air conditioner will decrease, and if the condensing temperature is not referred to or the frequency control when the air conditioner leaves the factory, the air conditioner will deviate in the frequency conversion process.
In some embodiments of the present application, the adjusting the wind speeds of the indoor unit and the outdoor unit according to the condensing temperature and the temperature difference includes:
and judging whether the temperature difference between the indoor temperature and the control temperature meets a first preset temperature condition or not according to the condensation temperature.
When the condensing temperature is considered, the temperature difference is not considered, so that the air conditioner is problematic in frequency conversion, for example, the set temperature is 26 degrees centigrade, but the indoor temperature is 10 degrees centigrade, which is too different from the requirement of the user, and if the frequency reduction is started, the user experience is poor. Therefore, taking the condensation temperature as a reference, the specific difference of the temperature difference also needs to be considered.
In some embodiments of the present application, the determining whether the temperature difference between the indoor temperature and the control temperature satisfies a first preset temperature condition according to the condensing temperature includes:
and if the condensation temperature is smaller than a preset first threshold value, adjusting the indoor unit to reduce the wind speed according to a preset first period, and judging whether the temperature difference between the indoor temperature and the control temperature meets a first preset temperature condition.
For example, the first threshold may be 40 degrees celsius, when the condensation temperature is less than 40 degrees celsius, the wind speed of the indoor unit needs to be controlled first, the first period may be a minutes, the a minutes may be 10 minutes, 15 minutes, and 20 minutes, the wind speed reduction mode may be a wind speed reduction gear, the wind speed reduction gear is a gear limit on the air conditioner control device, such as 1 gear, 2 gear, 3 gear, 4 gear, and 5 gear, and if the gear at this time is 5 gears, the indoor unit may be controlled to be reduced by one gear every 10 minutes.
However, it is also necessary to simultaneously determine whether the temperature difference satisfies the first preset temperature condition.

Next, as shown in fig. 3, fig. 3 is a schematic flow chart of an embodiment of a control method of an air conditioner in the embodiment of the present application, where the air conditioner further includes a cooling mode, and after the air conditioner is started and the control temperature of the air conditioner, the indoor temperature, and the condensation temperature of the heat exchanger in the indoor unit are obtained, the control method of the air conditioner may further include the following steps 301 and 302:
301. and if the air conditioner operates in the refrigeration mode, calculating the temperature difference between the control temperature and the indoor temperature.
In general, since the control conditions of the cooling mode and the heating mode are slightly different, the condensing temperature does not need to be considered in the cooling mode.
302. And adjusting the wind speeds of the indoor unit and the outdoor unit according to the temperature difference.
In the case of considering only the temperature difference, it is necessary to further narrow the range of the temperature difference and control the wind speeds of the indoor unit and the outdoor unit within the narrow range.

and judging whether the temperature difference meets a second preset temperature condition or not.
According to the above embodiments, the same parts will not be described herein. If the temperature difference is not refined, the air speed control of the air conditioner has great deviation when the temperature difference exceeds a certain range. For example: if the set temperature of the air conditioner is 26 degrees in the cooling mode, but the room temperature is 35 degrees, the temperature difference is 9 degrees, and the set temperature of the user is reached, and if the frequency reduction is started at this time, the user experience is poor.

The wind speed of the indoor unit is reduced every a minutes, and the wind speed reduction mode may be a wind speed reduction gear, where the wind speed reduction gear is a gear limit on the air conditioner control device, such as 1 gear, 2 gear, 3 gear, 4 gear and 5 gear, and if the gear is 5 gear, the indoor unit may be controlled to be reduced by one gear every a minutes. However, at this time, no additional control is made on the wind speed of the outdoor unit.
And if the temperature difference is within a preset second threshold value interval, adjusting the air conditioner to operate according to a control instruction on the control device.
The description of the second threshold interval is omitted here, where the temperature difference may still be greater than 0 ℃ and less than or equal to 1 ℃, and if the indoor temperature is 27 ℃ and the set temperature is 26 ℃, the temperature difference is 1 ℃, and the second threshold interval is satisfied, the first preset temperature condition is still satisfied, but at this time, the control parameter on the control device of the air conditioner needs to be maintained to operate the indoor unit, but no additional control is still performed on the outdoor unit.
And if the temperature difference is within a preset third threshold interval, adjusting the indoor unit to reduce the wind speed according to a preset second period, and adjusting the outdoor unit to reduce the wind speed according to the first period.
The same place as the above steps is not described herein again, wherein the third threshold interval may still be-2 ℃ < the temperature difference is less than or equal to 0 ℃, and if the indoor temperature is 25 ℃, and the set temperature is 26 ℃, the temperature difference is minus 1 ℃. When the third threshold interval is satisfied, the second preset temperature condition is still satisfied, and at this time, the second period may still be (a/2) min, and a may be 10 min, 15 min, and 20 min. The wind speed of the indoor unit is reduced every (a/2) minute, and the wind speed reduction mode may be a wind speed reduction gear, where the wind speed reduction gear is a gear limit on the air conditioner control device, such as 1 gear, 2 gear, 3 gear, 4 gear and 5 gear, and if the gear is 5 gear, the indoor unit may be controlled to be reduced by one gear every (a/2) minute, but the wind speed of the outdoor unit needs to be controlled, and the wind speed reduction mode is controlled to be reduced by one wind speed gear every a minute.
And if the temperature difference is within a preset fourth threshold interval, adjusting the indoor unit to reduce the wind speed according to a preset third period, and adjusting the outdoor unit to reduce the wind speed according to the second period.
The description of the fourth threshold interval is omitted here, where the fourth threshold interval may still be-4 ℃ < the temperature difference is less than or equal to-2 ℃, and if the indoor temperature is 23 ℃ at this time, and the set temperature is 26 ℃, the temperature difference is negative 3 ℃. If the fourth threshold interval is satisfied, the second preset temperature condition is still satisfied, and the third period may still be (a/3) minutes, and a may be 10 minutes, 15 minutes, and 20 minutes. The wind speed of the indoor unit is reduced every (a/3) minute, and the wind speed reduction mode may be a wind speed reduction gear, which is a gear limit on the air conditioner control device, such as 1 gear, 2 gear, 3 gear, 4 gear and 5 gear, and if the gear is 5 gear, the indoor unit may be controlled to be reduced by one gear every (a/3) minute, but the wind speed of the outdoor unit needs to be controlled, and the wind speed reduction mode is controlled to be reduced by one gear every (a/2) minute.

and judging whether the temperature difference between the indoor temperature and the control temperature is less than or equal to a preset third threshold value or not.
After the user turns on the air conditioner, the user may inadvertently perform an error operation, such as a cooling mode operation in winter, and an additional method is required to determine the operation of the air conditioner.
For example, the third threshold may be 3 degrees celsius, and when the user turns on the air conditioner in summer, the set temperature is 26 degrees in the heating mode, but the ambient temperature may be 30 degrees, the difference between the ambient temperature and the set temperature is 4 degrees, and the difference is greater than the third threshold, it may be determined that the environment in which the air conditioner operates is matched with the operation mode.

And if the air conditioner is larger than the third threshold, controlling the air conditioner to operate according to a control instruction on the control device.
If the ambient temperature is 30 degrees, the set temperature is 26 degrees in the cooling mode, and the down-conversion condition is not reached, and the air conditioner is operated according to the normal control parameters of the air conditioner.
In some embodiments of the present application, before determining whether a temperature difference between the indoor temperature and the control temperature is less than or equal to a preset third threshold, the method further includes:
and judging whether the temperature difference is smaller than or equal to a preset fourth threshold value, wherein the fourth threshold value is smaller than the third threshold value.
After the user turns on the air conditioner, the user may inadvertently perform an error operation, such as a cooling mode operation in winter, and an additional method is required to determine the operation of the air conditioner. An exemplary said fourth threshold may be negative 4 degrees.
And if the temperature difference is smaller than or equal to the fourth threshold value, stopping the air conditioner.
In winter, if the user mistakenly opens the cooling mode of the air conditioner, for example, the set temperature is 26 degrees in the cooling mode, but the ambient temperature may be 5 degrees, and the temperature difference is negative 25 degrees, which is much less than negative 4 degrees, at this time, it may be determined that the environment in which the air conditioner operates is not matched with the operation mode, and in order to avoid that the air conditioner operates all the time and wastes power, the operation of the indoor unit and the outdoor unit is stopped at this time.
And if the temperature difference is larger than the fourth threshold, judging whether the temperature difference between the indoor temperature and the control temperature is smaller than or equal to a preset third threshold.
If the temperature difference is greater than minus 4 degrees, the preset second temperature condition of the above embodiment is satisfied, and the air conditioner is regulated and controlled according to the adjusting method satisfying the second temperature preset condition, which is not described herein again.
