Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides an air conditioner control method, including:
acquiring a noise parameter; acquiring a preset noise threshold value; under the condition that the noise parameter is larger than a preset noise threshold value, controlling to reduce the rotating speed of the cross flow fan until the noise parameter is smaller than or equal to the preset noise threshold value; acquiring indoor temperature; and determining the working power of the compressor according to the rotating speed, the set temperature and the indoor temperature.
Wherein the noise parameter may be derived from a noise sensor in communicative connection with the air conditioner. The noise sensor may be installed outside or inside the air conditioner case. The noise sensor is mainly used for detecting noise generated by vibration of the cross flow fan.
During the operation of the air conditioner, the cross flow fan is first operated at a default rotational speed. The noise sensor synchronously detects decibel values of noise generated by the cross flow fan, namely noise parameters. And when the noise parameter is less than or equal to the preset noise threshold value, keeping the rotating speed of the cross flow fan unchanged. And when the noise parameter is larger than the preset noise threshold value, controlling the rotating speed of the cross flow fan to be reduced at a preset speed, synchronously detecting the noise parameter in the speed reduction process, and stopping speed reduction when the noise parameter is reduced below the preset noise threshold value. Thus, the crossflow fan is maintained at a rotational speed at which the noise generated is less than a predetermined noise threshold.
The indoor temperature can be obtained through a temperature sensor arranged at an air inlet of the air conditioner. It can be understood that the indoor temperature, i.e., the return air temperature of the air conditioner, achieves the cooling/heating effect set by the user while the return air temperature is maintained at the set temperature.
After the rotating speed of the cross flow fan is confirmed, the working power of the compressor is correspondingly adjusted according to the rotating speed, the set temperature and the indoor temperature, so that the refrigerating/heating capacity of the compressor can be balanced with the indoor heat dissipation capacity under the actual rotating speed of the cross flow fan, and the indoor temperature is stably maintained at the set temperature.
The air conditioner control method provided by the invention can reduce the rotating speed of the cross flow fan when the noise parameter generated by the cross flow fan is larger than the preset noise threshold value until the noise parameter is reduced to be less than or equal to the preset noise threshold value. Therefore, the noise generated by the air conditioner is effectively reduced through the stepless speed regulation of the cross flow fan. And because a stepless speed regulation method is adopted, the cross flow fan can work at the maximum rotating speed which ensures that the noise parameter is less than the preset noise threshold value, and the power requirement on the compressor is reduced.
On the basis of the above embodiments, optionally, in some embodiments of the present invention, the step of determining the operating power of the compressor according to the rotation speed, the set temperature and the indoor temperature includes:
calculating the temperature difference, wherein in the cooling mode, the temperature difference is the value obtained by subtracting the set temperature from the indoor temperature, and in the heating mode, the temperature difference is the value obtained by subtracting the indoor temperature from the set temperature; controlling the compressor to work at a set power under the condition that the temperature difference belongs to a preset range; and controlling the compressor to work at the maximum power under the condition that the temperature difference is higher than the upper limit of the preset range.
It can be understood that the temperature difference is greater than zero just after the air conditioner is turned on in the cooling/heating mode, and the temperature difference is generally large. After the air conditioner is continuously operated for a certain period of time in the cooling/heating mode, the indoor temperature gradually approaches the set temperature and is maintained at about the set temperature. Thus, the preset range can be set to a smaller allowable range of fluctuation, such as-1 to 1 ℃ or-2 to 2 ℃. When the temperature difference falls within the preset range, the current indoor temperature and the set temperature can be considered to be balanced, and at the moment, the compressor is enabled to work at the set power so as to maintain the indoor temperature to be stable. Under the condition that the temperature difference is higher than the upper limit of the preset range, for example, the preset range is-1 ℃ and the temperature difference is more than 1 ℃, the air conditioner at the moment can be considered to be in the process of adjusting the room temperature to be rapidly reduced in the cooling mode or the process of adjusting the room temperature to be rapidly increased in the heating mode, and the compressor is controlled to work at the maximum power no matter the rotating speed of the cross flow fan at the moment, so that the indoor temperature can rapidly reach the set temperature.
On the basis of the above embodiments, optionally, in some embodiments of the present invention, the step of controlling the compressor to operate at the set power includes: acquiring set power, wherein the set power is the power corresponding to the current set temperature and the current set rotating speed, and controlling the compressor to work at the set power; controlling the working power of the compressor to be increased under the condition that the compressor works at the set power and the temperature difference is increased to be higher than the upper limit of the preset range; under the condition that the compressor works at the set power and the temperature difference is reduced to be lower than the lower limit of the preset range, controlling the working power of the compressor to be reduced; and storing the increased or decreased working power as the new set power.
It can be understood that a corresponding relation table of the rotational speed of the cross flow fan, the set temperature and the power of the compressor is stored in the control device of the air conditioner. The corresponding relation table includes the set power that the compressor should have when the cross flow fan works at the rotating speed of different gears under each set temperature. Under a general condition, when the temperature difference is within a preset range and the compressor works in a certain gear, the compressor is controlled to work at a corresponding set power, and the temperature difference can be maintained to be stable. When the cross flow fan is subjected to stepless speed regulation to enable the noise parameter to be lower than the preset noise threshold value, the rotating speed of the cross flow fan may be different from the rotating speed of any gear in the corresponding relation table. And calling the set power corresponding to the first gear of the rotating speed closest to the rotating speed of the current cross-flow fan in the corresponding relation table as the working power of the compressor.
Because the rotating speed of the cross flow fan corresponding to the set power is inconsistent with the actual rotating speed, and the indoor heat dissipation capacity in different environments may have differences, after the compressor is controlled to work at the set power initially set in the air conditioner, the refrigerating/heating capacity of the air conditioner may not meet the actual requirements, so that the temperature difference cannot be maintained within the preset range under the current rotating speed of the cross flow fan and the current set power of the compressor. Correspondingly, when the compressor works at the set power and the temperature difference fluctuates, the working power of the compressor is adjusted according to the condition that the temperature difference is higher than or lower than the upper limit or the lower limit of the preset range until the temperature difference can be stably kept in the preset range. It can be understood that the working power of the compressor at this time is the power corresponding to the current actual rotational speed of the crossflow fan and the current heat dissipation capacity of the environment, so that the indoor temperature of the environment where the current air conditioner is located can be stably maintained at the temperature near the set temperature. The power is stored in the correspondence table as a new set power of the compressor at the current set temperature and the current actual crossflow fan speed. Under the condition that the air conditioner operates at the same set temperature and the same rotational speed of the cross-flow fan next time, the updated set power of the compressor matched with the actual rotational speed of the cross-flow fan can be directly obtained when the temperature difference is reduced to the preset range, so that the power adjusting process of the compressor is favorably saved or simplified. After the air conditioner is installed in a fixed environment and operated for a period of time, the initial corresponding relation table in the air conditioner is updated to a corresponding relation table which is suitable for the installation environment of the air conditioner and the stepless speed regulation of the cross flow fan.
For example, in one embodiment, the predetermined range is-2 to 2 ℃, i.e., the upper limit is 2 ℃ and the lower limit is-2 ℃. When the air conditioner is just started in a refrigeration mode, the indoor temperature is obviously higher than the set temperature, the temperature difference is higher than the upper limit of the preset range, the rotating speed of the cross-flow fan is controlled to meet the noise requirement, and the compressor is controlled to work at the maximum power until the temperature difference is reduced to-2 ℃. If the corresponding relation table comprises the set power of the compressor corresponding to the actual rotating speed of the current cross-flow fan at the set temperature, controlling the compressor to work at the set power; if the corresponding relation table does not include the set power, the compressor is controlled to work on the set power corresponding to the rotating speed of the cross flow fan closest to the actual rotating speed. Then, according to the fluctuation of the temperature difference, when the temperature difference rises to be more than 2 ℃, the working power of the compressor is controlled to be increased until the temperature difference falls back to be below 2 ℃; when the temperature difference is reduced to be less than minus 2 ℃, the working power of the compressor is controlled to be reduced until the temperature difference is increased back to be more than minus 2 ℃. And when the temperature difference is recovered to-2 ℃, storing the current working power of the compressor as the set power of the compressor corresponding to the actual rotational speed and the set temperature of the cross-flow fan at present so as to be convenient for calling next time.
On the basis of the above embodiments, optionally, in some embodiments of the present invention, the method further includes the steps of: judging whether the indoor temperature can reach the set temperature or not under the conditions that the compressor works at the maximum power under the current rotating speed and the set temperature; if the indoor temperature cannot reach the set temperature, judging whether the air conditioner operates in a forced noise reduction mode; and if the air conditioner operates in the forced noise reduction mode, controlling the compressor to work at the maximum power.
It can be understood that after the rotational speed of the cross flow fan is reduced to reduce the noise generated by the cross flow fan, compared with an air conditioner without reducing the rotational speed, the air conditioner control method provided by the invention needs to control the working power of the compressor to be higher under the same set temperature so as to compensate for the reduced refrigeration/heating capacity of the cross flow fan. In some cases, such as where the preset noise threshold is set too low, the rotational speed of the crossflow fan is low, requiring the compressor to operate at a higher power. Therefore, it is determined whether the cooling/heating amount generated by the compressor and the cross flow fan together can maintain the room temperature around the set temperature when the compressor is operated at the maximum power. If not, the current set temperature exceeds the limit which can be reached by the air conditioner under the current rotational speed of the cross flow fan. And judging whether the air conditioner operates in a forced noise reduction mode, and if the air conditioner operates in the forced noise reduction mode, controlling the compressor to work at the maximum power without changing the rotating speed of the cross-flow fan. That is, in the forced noise reduction mode, noise control is prioritized over temperature control, and a part of the cooling/heating amount is sacrificed to achieve the effect that the noise parameter is smaller than the preset noise threshold.
The manner of determining whether the indoor temperature can reach the set temperature may be various. For example, the outlet air temperature when the compressor is operated at the maximum power is directly obtained, and if the outlet air temperature is higher than the set temperature in the cooling mode or lower than the set temperature in the heating mode, it indicates that the indoor temperature cannot reach the set temperature.
Optionally, in some embodiments, if the air conditioner is not operated in the forced noise reduction mode, the compressor is controlled to operate at the maximum power, and the rotational speed of the cross-flow fan is controlled to be increased until the indoor temperature can reach the set temperature. That is, in the non-forced noise reduction mode, the temperature control is prioritized over the noise control, and when the current set temperature exceeds the limit that the air conditioner can reach at the current cross flow fan rotational speed, the cross flow fan rotational speed is increased correspondingly so as to operate at the rotational speed that satisfies the current set temperature and generates the minimum noise.
Optionally, in other embodiments, if the air conditioner is not operating in the forced noise reduction mode, the air conditioner may be further controlled to send a prompt to a user, and the user is prompted to select the forced noise reduction mode or to modify the preset noise threshold correspondingly.
On the basis of the foregoing embodiments, optionally, in some embodiments of the present invention, the step of obtaining the preset noise threshold includes: judging whether a noise threshold input value input from the outside is received; if the noise threshold input value is received, controlling the preset noise threshold to be equal to the noise threshold input value; and if the input value of the noise threshold value is not received, generating a default value of the noise threshold value, and controlling a preset noise threshold value to be equal to the default value of the noise threshold value.
The user can input the noise threshold input value to the air conditioner through a remote controller or smart phone software in communication connection with the air conditioner, and the like, so that specific requirements are met. For example, when the number of people in a room is large, the input value of the noise threshold is set to be high, and when the number of people in the room is large, the input value of the noise threshold is set to be low. And if the user does not input the noise threshold input value, the air conditioner generates a default noise threshold value. The default noise threshold may be a predetermined fixed value, such as 60 db during the daytime and 30 db during the nighttime.
On the basis of the foregoing embodiments, optionally, in some embodiments of the present invention, the step of obtaining the preset noise threshold includes: storing the preset noise threshold as a historical preset noise threshold in the parameter record. The step of generating a noise threshold default value comprises: acquiring a historical preset noise threshold in the parameter record; and calculating the average value of the historical preset noise threshold, and taking the average value as the default value of the noise threshold.
It can be understood that, each time a user inputs a noise threshold input value to the air conditioner through a remote controller or smart phone software, the air conditioner controls the preset noise threshold to be equal to the noise threshold input value correspondingly, and simultaneously records the preset noise threshold as a historical preset noise threshold, so as to update the parameter record of the preset noise threshold. And when the noise threshold default value needs to be calculated next time, the air conditioner acquires the historical preset noise threshold value in the updated parameter record and calculates the average value so as to generate a new noise threshold value default value.
The air conditioner control method provided by the embodiment of the invention can enable the air conditioner to generate the default value of the noise threshold according to the preset noise threshold selected by the user after a period of time of the air conditioner, so that the default value of the noise threshold automatically adapts to the setting habit of the user, and the operation convenience is improved.
Based on the foregoing embodiments, in some embodiments of the present invention, the step of storing the preset noise threshold as a historical preset noise threshold in the parameter record includes: judging whether the time period for storing the preset noise threshold is a daytime time period or a nighttime time period; if the time interval is a daytime time interval, storing a preset noise threshold as a historical preset noise threshold in the daytime parameter record; and if the time interval is the night time interval, storing the preset noise threshold as a historical preset noise threshold in the night parameter record. And the step of obtaining a historical preset noise threshold in the parameter record comprises: judging whether the current time interval is a daytime time interval or a nighttime time interval; if the current time interval is the daytime time interval, acquiring a historical preset noise threshold value in the night parameter record; and if the current time interval is the night time interval, acquiring a historical preset noise threshold value in the night parameter record.
It will be appreciated that there may be a large difference in the noise requirements of the user between the daytime hours and the nighttime hours. When the air conditioner stores the preset noise threshold, the daytime parameter record and the night parameter record can be respectively formed according to the storage time. When the default value of the noise threshold is generated, the day parameter record or the night parameter record is called correspondingly according to the current time period as the day time period or the night time period, and the average value of historical preset noise thresholds in the day parameter record or the night parameter record is calculated to be used as the default value of the noise threshold in the day time period or the night time period.
