Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. 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.
Example one
The embodiment provides an air conditioner control method which is applicable to accurate control of air circulation. The air conditioner comprises a main body and a control assembly thereof, wherein the main body comprises a heat exchanger, a machine valve, a motor, an air outlet and the like which are sequentially connected. Fig. 1 is a flowchart of an air conditioner control method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
and S101, acquiring the actual air outlet speed of the air conditioner.
Wherein, can install wind speed measuring instrument in air outlet department to measure the actual air-out speed of air conditioner. The wind speed measuring instrument can actively measure the wind outlet speed in real time, and can also passively measure the wind outlet speed based on a fan rotating speed adjusting signal after the rotating speed of the fan is adjusted; and then transmitting the measured air outlet speed to a corresponding module.
And S102, determining an air circulation reference value of the target area according to the actual air outlet speed.
The target area is an operation area of the air conditioner. The air circulation reference value is a numerical value representing the unobstructed degree of air circulation in the target area, and the dirty and blocked conditions of the air conditioner, such as whether the filter screen is dirty and blocked, can be known according to the numerical value.
And S103, controlling the air conditioner to operate according to the air circulation reference value.
For example, if the air circulation reference value indicates that the air conditioner is slightly dirty, the rotating speed of the fan can be increased to accelerate air circulation and offset the slow circulation caused by the dirty blockage to a certain extent; if the air circulation reference value indicates that the air conditioner is normal and no dirty or blocked condition exists, the current rotating speed of the fan can be kept.
According to the embodiment, the reference value for representing the unobstructed degree of the air circulation of the target area is determined according to the actual air outlet speed of the air conditioner, the air conditioner is controlled to operate according to the reference value, and the accurate control of the air circulation of the target area is realized.
Specifically, the process of calculating the air circulation reference value is performed periodically, the period may be preset before the air conditioner leaves a factory, and specifically may be set according to a time period required for the air conditioner to completely circulate the air in the corresponding space once at a certain air speed. And for each period, determining the air circulation reference value of the current period according to the actual air outlet speed of the air conditioner in the current period. The air circulation reference value is periodically calculated, the air circulation of the target area is controlled according to the actual condition, and the timely monitoring and accurate control of the air circulation condition of the target area can be realized.
Optionally, the step S102 of determining an air circulation reference value of the target area according to the actual air outlet speed includes: determining an air circulation speed index value of a target area according to the actual air outlet speed; and calculating the ratio of the air circulation speed index value to a preset air circulation speed threshold value to obtain an air circulation reference value.
Further, determining an index value of air circulation speed of the target area according to the actual air outlet speed, comprising: calculating the total amount of air required to be circulated in the current period according to the space size of the target area and the air density of the target area at the beginning of the current period; calculating the effective air output of the air conditioner in the current period according to the actual air output speed, the opening of the air port, the air output duration and the air exchange loss rate; and calculating the ratio of the effective air output of the air conditioner to the total air amount to obtain the air circulation speed index value of the current period.
Wherein the current period is the period followed by the calculation of the air circulation reference value as described above. For each cycle, the total amount of air that needs to be circulated for the cycle needs to be calculated. The total amount of air is calculated based on the size of the space in the target area and the air density in the target area. The air conditioners have applicable space size ranges, and the corresponding target area space size can be input into the control module according to the actual assembly condition of the air conditioners. The air density of the target area may be measured directly using a density measuring instrument, or the air pressure and temperature of the target area may be measured, and then the corresponding air density is obtained by table lookup.
The size of the space affects the air exchange of the space, and in a space with a small area, the loss of the air-conditioning air from exchanging new air with old air is small, and in a space with a large area, the loss of the air-conditioning air from exchanging new air with old air is large. That is, the fresh air actually blown out by the air conditioner loses a certain amount, and the air exchange loss rate is in a proportional relationship with the space size. The air conditioner air outlets have different opening degrees and different ventilation areas, and the corresponding air outlet volumes are also different. If the air conditioner is provided with the air guide plate, the opening degree of the air opening refers to the opening degree of the air guide air opening. According to the air-out speed, the air opening and the air-out duration of the air conditioner, the actual air-out quantity of the air conditioner can be calculated, and when the product of the actual air-out quantity of the air conditioner and the loss rate (namely the effective air-out quantity of the air conditioner) is equal to the total quantity of air needing to be circulated in a target area, the air quantity newly blown out by the air conditioner completely replaces the original total quantity of air, so that one-time air circulation is completed.
If the air outlet speed changes in the current period, the air outlet volume corresponding to each air outlet speed and the corresponding air inlet opening and air outlet duration in the current period need to be calculated respectively, the actual air outlet volume in the current period is obtained by adding the air outlet volumes, and then the effective air outlet volume of the air conditioner in the current period is calculated by combining the air exchange loss.
The preset air circulation speed threshold value can be preset before the air conditioner leaves a factory or can be determined when the air conditioner operates for the first time. Specifically, before calculating the ratio of the air circulation speed index value to the preset air circulation speed threshold, the method further includes: when the air conditioner operates for the first time, calculating an air circulation speed index value in a preset time length to serve as a preset air circulation speed threshold value. The calculation of the air circulation speed index value refers to the aforementioned steps, and is not described herein again. The preset time period may be equal to the time period of the calculation period of the air circulation reference value. When the air conditioner operates for the first time, no dust exists on the filter screen of the air conditioner, the default air conditioner is smooth, the air circulation speed index value of the target area during the first operation is used as the preset air circulation speed threshold value, and the air circulation reference value of the target area can be accurately obtained.
In an alternative embodiment, the S103 controls the air conditioner to operate according to the air circulation reference value, including: if the air circulation reference value is larger than a preset threshold value and the circulation mode is started, detecting the air quality of the target area according to a preset time interval, and controlling the air conditioner to operate according to the air quality; and if the air circulation reference value is smaller than the preset threshold value, prompting maintenance information. The air circulation of the target area can be more accurately controlled by controlling the operation of the air conditioner in combination with the air circulation reference value and the air quality.
The air circulation reference value is larger than the preset threshold value, which indicates that the air circulation of the target area is relatively smooth, and the circulation speed can be further controlled. The air circulation reference value is smaller than the preset threshold value, which indicates that the air conditioner may be dirty and blocked, affects the normal circulation of air, and prompts maintenance information, for example, prompts a user to maintain an air inlet and an air outlet, clean or replace a filter screen, and the like. And under the condition that the air circulation reference value is equal to the preset threshold value, the air conditioner can be further controlled or any condition of maintenance is prompted according to the actual requirement. Air quality (also referred to as air freshness) includes: the ratio of carbon dioxide to oxygen in the air, the amount of particulates in the air (e.g., PM2.5), etc. The preset time interval is less than the calculation period of the air circulation reference value.
According to the air circulation reference value, the dirty and blocked condition of the air conditioner (i.e. the unobstructed degree of the air circulation) can be determined, as shown in the following table, wherein V1 represents a preset air circulation speed threshold value, and V2 represents an air circulation speed index value of the current period.
TABLE 1 air circulation reference value and air conditioner filth blocking condition comparison table
| Air circulation reference value V2/V1% by 100% | Degree of smoothness of air circulation |
| 0～20％ | Extreme filth blockage |
| 20％～40％ | Severe filth blockage |
| 40％～60％ | Moderate filth blockage |
| 60～80％ | Slight filth blockage |
| >80％ | Is normal |
And when the air circulation reference value is less than 40%, directly prompting a user to clean or replace the filter screen and other related maintenance information.
Further, the operation of the air conditioner is controlled according to the air quality, and the method comprises the following steps: judging whether the air quality meets the preset requirement; if not, controlling the air conditioner to increase the rotating speed of the fan according to a preset rule; and if so, controlling the air conditioner to suspend detecting the air quality.
The preset requirements may include a carbon dioxide to oxygen ratio threshold, an air particle threshold, and the like. The preset rule is mainly a rule for increasing the rotating speed of the fan, and specifically relates to increasing the amplitude and the frequency of the rotating speed of the fan, for example, only increasing the rotating speed of the fan once according to a larger amplitude, specifically, after the rotating speed of the fan is increased according to a first preset amplitude (at this time, the fan runs at a larger rotating speed), and the next detection of the air quality still does not meet the requirement, the rotating speed of the fan is continuously kept running, and the rotating speed of the fan is not continuously increased; if the fan rotating speed is increased for multiple times according to a smaller amplitude, specifically, after the fan rotating speed is increased according to a second preset amplitude, the next time the detected air quality still does not meet the requirement, the fan rotating speed is increased according to the second preset amplitude, and the process is repeated until the maximum fan rotating speed value is increased or the air quality meets the preset requirement. Wherein the first predetermined amplitude is greater than the second predetermined amplitude.
If the air quality meets the preset requirement, the air in the target area has no great influence on the comfort level of the user, the operation of the air conditioner can be not adjusted, the calculation of the air circulation reference value in the next period is waited, and corresponding operation is executed according to the calculation result. For a fresh air conditioner, under the condition that the circulation of the air conditioner is smooth, if the air quality of a target area does not meet the preset requirement, the air output is increased by controlling the rotating speed of a fan, so that the air circulation of the target area can be accelerated, the air quality of the target area meets the preset requirement as soon as possible, and the comfort level of a user is improved; for ordinary air conditioner, under the more unobstructed condition of air conditioner circulation, if the air quality does not accord with preset requirement, increase the air output through increasing the fan rotational speed, can accelerate the inside air cycle of target area, can alleviate the uncomfortable that the air quality does not accord with to a certain extent and preset the requirement and bring for the user.
In order to ensure the comfort and prevent the temperature from being reduced more, the running frequency of the compressor can be properly reduced while the rotating speed of the fan is increased by controlling the air conditioner.
In an alternative embodiment, the method further comprises: relevant parameters of the air circulation are displayed. So that the air circulation condition of the target area can be intuitively reflected. Wherein, the relevant parameters of the air circulation comprise: actual air outlet speed, air opening, air outlet duration, air circulation reference value, air circulation speed index value, air conditioner filth blockage condition and the like. Of course, besides displaying relevant parameters of air circulation, the air quality can also be displayed, so that a user can conveniently view and know the air quality of a target area.
Illustratively, as shown in fig. 2, after the air conditioner is assembled, the corresponding target area space size is input in the processing module. When the air conditioner operates for the first time, an air circulation speed index value V1 of a target area is calculated, the value is used as a preset air circulation speed threshold value, then the air circulation speed index value V2 of each period is periodically calculated according to a period T1, the air circulation speed index value V2 of the current period is calculated according to the actual air outlet speed in the current period, V2 is compared with V1 to obtain an air circulation reference value of the current period, and the condition of dirty blockage of the air conditioner is confirmed by looking up a table, at the moment, the operation of the air conditioner can be controlled only according to the air circulation reference value, for example, the air circulation reference value corresponds to the condition of slight dirty blockage, and the rotating speed of a fan can be increased. Meanwhile, relevant parameters and air quality of air circulation can be displayed through the display module, and a user can conveniently check the parameters and the air quality. Preferably, the air conditioner may be controlled to operate in conjunction with the air circulation reference value and the air quality, and in the case that the air circulation reference value is greater than the preset threshold, the air conditioner periodically determines the air quality of the target area according to a period T2 and performs corresponding control. Specifically, the air quality of a target area is obtained, and whether the air quality is greater than a preset air threshold value is judged; if so, controlling the unit to increase the rotating speed of the fan, increasing the air output, accelerating the air circulation of the target area, and simultaneously displaying the circulation condition after the air output is increased. And when the air volume is increased for a certain time (T2), judging the air quality again, and if the air quality is still greater than the preset air threshold, keeping the existing air speed running or continuously increasing the rotating speed of the fan according to the preset amplitude. After a certain time (T2), the air quality is determined again, and if the air quality is less than the preset air threshold, the detection of the air quality is suspended.
