Control methods and apparatuses of air conditioning apparatuses and air conditioning apparatuses according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a control method of an air conditioning apparatus according to an embodiment of the present application.
In the embodiment of the application, the air conditioning device can be an air conditioner, an air purifier and other electrical equipment. Wherein, the indoor unit of the air conditioning device is provided with an air outlet, and the air outlet is provided with an air guide component; the air duct communicated with the air outlet is internally provided with a purifying unit, and the indoor unit is also provided with an air quality detecting unit.
As shown in fig. 1, the control method of the air conditioning apparatus includes the steps of:
step 101, an air quality detection unit is controlled to detect air quality.
In the embodiment of the application, the air quality detection unit is used for detecting the gas pollution in the space where the air conditioning device is locatedConcentration of contaminants and/or concentration of immobilized contaminants (mg/m 3 ) Wherein the gaseous contaminants include formaldehyde, benzene, ozone, nitrogen oxides NOx (e.g., nitrous oxide N) 2 O, nitric oxide NO, nitrogen dioxide NO 2 Dinitrogen trioxide N 2 O 3 Dinitrogen tetroxide N 2 O 4 And dinitrogen pentoxide N 2 O 5 Etc.), total volatile organics (Total Volatile Organic Compounds, TVOC for short), etc., and solid contaminants include total suspended particulates (Total Suspended Particulates, TSP for short), inhalable particulates PM10, PM2.5, etc.
In the embodiment of the application, the air quality detection unit may be a related sensor, and the air quality is determined according to the detected gas pollutant concentration and/or the fixed pollutant concentration in the indoor environment by detecting the gas pollutant concentration and/or the fixed pollutant concentration by the related sensor, for example, the PM2.5 concentration may be detected by the PM2.5 sensor, the formaldehyde concentration may be detected by the formaldehyde sensor, the TVOC concentration may be detected by the TVOC sensor, and the like. For example, air quality is better when the gas contaminant concentration is lower and the stationary contaminant concentration is lower, and air quality is lower when the gas contaminant concentration is higher and/or the stationary contaminant concentration is higher.
And 102, starting a purifying unit to purify the gas in the air duct according to the air quality.
In an embodiment of the application, the air quality is used for indicating the pollutant concentration in the space where the air conditioning device is located, wherein the pollutant concentration comprises a gas pollutant concentration and/or a fixed pollutant concentration. Specifically, when the contaminant concentration includes only the gas contaminant, the gas contaminant concentration detected by the air quality detecting unit may be directly used as the contaminant concentration in the space where the air conditioning apparatus is located; when the pollutant concentration only comprises solid pollutants, the solid pollutant concentration detected by the air quality detection unit can be directly used as the pollutant concentration in the space where the air conditioning device is located; when the pollutant concentration includes both the gas pollutant concentration and the solid pollutant concentration, the gas pollutant concentration and the solid pollutant concentration detected by the air quality detection unit can be directly weighted and summed to obtain the pollutant concentration in the space where the air conditioning device is located, for example, the weight values corresponding to the gas pollutant concentration and the solid pollutant concentration can be preset, and after the gas pollutant concentration and the solid pollutant concentration detected by the air quality detection unit, the gas pollutant concentration and the solid pollutant concentration can be weighted and summed according to the weight values corresponding to the gas pollutant concentration and the solid pollutant concentration to obtain the pollutant concentration in the space where the air conditioning device is located.
When the number of the types of the gas pollutants is plural, after the concentration of each gas pollutant is obtained, the concentration of the plural gas pollutants may be weighted and summed to obtain the concentration of the gas pollutant in the space where the air conditioning device is located, for example, after the formaldehyde concentration, the NOx concentration and the TVOC concentration are detected, the formaldehyde concentration, the NOx concentration and the TVOC concentration may be weighted and summed according to the preset weight values corresponding to the formaldehyde concentration, the NOx concentration and the TVOC concentration to obtain the concentration of the gas pollutant in the space where the air conditioning device is located. Similarly, when the number of the types of the solid pollutants is plural, after the concentration of each type of the solid pollutants is obtained, the concentrations of the plural types of the solid pollutants can be weighted and summed to obtain the concentration of the solid pollutants in the space where the air conditioning device is located.
In the embodiment of the application, the purifying unit is used for purifying solid pollutants and/or gas pollutants in the air duct, and when the purifying unit is used for purifying the solid pollutants (such as inhalable particulate matters PM10, PM2.5 and the like), the purifying unit is mainly used for adsorbing the solid pollutants so as to achieve the purpose of purifying air, and the purifying unit can be used for adsorbing or decomposing the gas pollutants (such as formaldehyde, total volatile organic compounds (TVOC for short), and the like). For example, when the gaseous pollutant is formaldehyde, it can be decomposed by a purification unit to obtain carbon dioxide CO 2 And water H 2 0 or when the gas pollutant is chlorine-containing volatile organic compound, decomposing the gas pollutant by using a purifying unit to obtain dioxygenCarbon CO conversion 2 Water H 2 0, and others, without limitation.
It will be appreciated that when the concentration of gaseous contaminants is low and the concentration of fixed contaminants is low, at this point the air quality is better and the user is more comfortable in the space in which the air conditioning device is located, and therefore, the purification unit may not need to be activated to purify the air in the air duct, and when the concentration of gaseous contaminants is high and/or the concentration of fixed contaminants is high, the air quality is low, at this point the purification unit may be activated to purify the air in the air duct to promote the comfort of the environment in the space in which the air conditioning device is located.
Therefore, in the embodiment of the application, when the air quality indicates that the concentration of the pollutant is greater than the threshold value, the purifying unit arranged in the air duct communicated with the air outlet can be started to purify the air in the air duct, so that the air quality of the air outlet is improved, and the comfort of the environment in the space where the air conditioning device is located is further improved. And when the air quality indicates that the contaminant concentration is less than or equal to the threshold value, no treatment may be performed.
The threshold value may be preset by a built-in program of the air conditioning apparatus, or may be set by a user in order to improve the applicability and flexibility of the control method, which is not limited. It should be understood that the threshold is a safe concentration suitable for the human living environment.
Step 103, detecting the pollutant removal efficiency of the purification unit when the air guide assembly swings to each swing angle.
In the embodiment of the present application, each swing angle may be preset, for example, when the air guiding assembly includes an air guiding plate for swinging up and down and a swing blade for swinging left and right, each swing angle may include each swing angle in a vertical direction and each swing angle in a horizontal direction.
According to the embodiment of the application, when the purifying unit purifies the air in the air duct, the air guide assembly can be controlled to swing to each swing angle so as to accelerate the air flow and air circulation in the space where the air conditioning device is located, thereby improving the pollutant removal efficiency.
As a possible implementation manner, when the air guide assembly includes the air guide plate for swinging up and down and the swing blade for swinging left and right, one of the air guide plate and the swing blade may be kept motionless, the other may be controlled to swing in the swinging direction thereof according to each swinging angle, for example, the swing blade may be kept motionless, and the air guide plate may be controlled to sweep air in the up, middle and down directions in sequence in the vertical direction. Or, the swing angle of one of the air deflector and the swing blade may be adjusted first, after the swing angle is adjusted, the other may be controlled to swing in the swing direction thereof according to each swing angle, then, one may be adjusted continuously to the other swing angle, after the swing angle is adjusted, the other may be controlled to swing in the swing direction thereof according to each swing angle, and so on until the air deflector and the swing blade swing in each swing angle.
For example, three examples of swinging angles are included in the vertical direction and the horizontal direction respectively, that is, the air deflector can sweep in the up, middle and down directions, the swing blade can sweep in the left, middle and right directions, when the air deflector is adjusted to sweep in the up direction, the swing blade can be controlled to swing in the left, middle and right directions respectively, then the air deflector can be adjusted to sweep in the middle direction, the swing blade can be controlled to swing in the left, middle and right directions respectively, then the air deflector can be adjusted to sweep in the down direction, and the swing blade can be controlled to swing in the left, middle and right directions respectively. In the above-described example, only three oscillation angles are used for each oscillation direction (horizontal direction or vertical direction), and in order to achieve the acceleration of the air flow in practical application, the number of oscillation angles in each oscillation direction may be divided into fine particles, for example, the number of oscillation angles in each oscillation direction may be divided into 4, 5, 6, or the like, which is not limited thereto.
According to the embodiment of the application, when the air guide assembly swings to each swinging angle, the pollutant removal efficiency of the purifying unit can be calculated according to the pollutant concentration detected by the air detecting unit. Where removal efficiency may refer to the rate of change of contaminant concentration per unit time. For example, when the air guide assembly swings to a certain swing angle, the pollutant concentration detected by the air detection unit at the moment, for example, marked as C1, and after a unit time period elapses, the pollutant concentration at the detection side of the air detection unit can be obtained again, for example, marked as C2, the removal efficiency is as follows: 100% |c2-c1|/C1.
And 104, controlling the swing of the air guide assembly according to the removal efficiency of each swing angle.
It can be understood that when the air guide assembly swings to a certain swing angle, the higher the removal efficiency corresponding to the swing angle is, the better the purifying effect of the air conditioning equipment at the swing angle is indicated, and the lower the removal efficiency corresponding to the swing angle is, the worse the purifying effect of the air conditioning equipment at the swing angle is indicated. Therefore, as a possible implementation manner of the embodiment of the present application, in order to ensure the purifying effect of the air conditioning apparatus, so as to improve the removing efficiency of the pollutant, the swing angle of the air guiding assembly may be controlled according to the swing angle with the highest removing efficiency.
According to the control method of the air conditioning device, the air quality is detected by controlling the air quality detection unit, the purification unit is started to purify the air in the air duct according to the air quality, then the pollutant removal efficiency of the purification unit is detected when the air guide assembly swings to each swing angle, and finally the swing of the air guide assembly is controlled according to the removal efficiency of each swing angle. Therefore, the pollutant removal efficiency can be improved, and the comfort of the environment in the space where the air conditioning device is located can be improved.
As a possible implementation manner, when the air guide assembly swings to each swing angle, the air guide assembly can be controlled to continuously supply air under each swing angle, and then the removal efficiency of each swing angle in unit time can be determined according to the duration of continuous air supply, the concentration of pollutants before continuous air supply and the concentration of pollutants after continuous air supply under each swing angle. The above process will be described in detail with reference to fig. 2.
Fig. 2 is a flowchart illustrating a control method of an air conditioning apparatus according to a second embodiment of the present application.
As shown in fig. 2, the control method of the air conditioning apparatus may include the steps of:
in step 201, the control air quality detecting unit detects air quality.
Step 202, determining whether the pollutant concentration indicated by the air quality is greater than a threshold value, if so, executing step 204, and if not, executing step 203.
Step 203, do nothing.
And 204, starting a purifying unit to purify the gas in the air duct.
The execution of steps 201 to 204 may be referred to the execution of steps 101 to 102 in the above embodiment, and will not be described herein.
Step 205, detecting the pollutant removal efficiency of the purification unit when the air guide assembly swings to each swing angle.
In the embodiment of the application, when the air guide assembly swings to each swinging angle, the air guide assembly can be controlled to continuously supply air under each swinging angle, and the continuous air supply duration, the pollutant concentration before continuous air supply and the pollutant concentration after continuous air supply under each swinging angle are obtained, so that the removal efficiency of each swinging angle in unit duration is determined according to the continuous air supply duration, the pollutant concentration before continuous air supply and the pollutant concentration after continuous air supply under each swinging angle.
For example, under a certain swing angle, the duration of continuous air supply is T, the concentration of the pollutant before continuous air supply is C3, and the concentration of the pollutant after continuous air supply is C4, and then the removal efficiency of the swing angle in unit duration is: 100% |c4-c3|/(C3T).
Step 206, determining the swing angle with highest removal efficiency according to the removal efficiency.
In the embodiment of the application, after the air guide assembly swings to each swing angle, the corresponding removal efficiency can be calculated, so that after the air guide assembly swings at each swing angle, all the calculated removal efficiencies can be obtained, then all the removal efficiencies can be compared in pairs, the highest removal efficiency is determined, and the swing angle with the highest removal efficiency can be determined.
And step 207, controlling the swing of the air guide assembly according to the swing angle with the highest removal efficiency.
In the embodiment of the application, after determining the swing angle with the highest removal efficiency, the air guide assembly can be controlled to supply air at the swing angle so as to accelerate the removal of pollutants, or the air guide assembly can be controlled to reduce the swing speed at the swing angle so as to increase the purification duration of the purification unit in a preset range containing the swing angle and improve the purification amount of pollutants, or the air guide assembly can be controlled to swing back and forth in a set angle range, wherein the set angle range contains the swing angle, for example, the swing angle is marked as w, the set angle range can be [ w-delta, w+delta ], wherein delta is a preset smaller angle value so as to accelerate the gas flow and the air circulation in the space where the air conditioning device is located, and thus the removal efficiency of pollutants is improved.
According to the control method of the air conditioning device, when the air quality indicates that the concentration of pollutants is smaller than or equal to the threshold value, no processing is performed, and therefore the power consumption of the air conditioning equipment can be saved. Through controlling the swing of wind-guiding subassembly according to the swing angle that gets rid of efficiency highest, can accelerate the gas flow and the air cycle in the space that air conditioning device is located to promote the removal efficiency of pollutant.
As one possible implementation manner, when the number of the air inlets communicated with the air duct is at least two, the air inlet is respectively arranged in the indoor unit and the outdoor air inlet pipe connected with the indoor unit, when the air is introduced from the air inlet of the indoor unit, the air can be purified through the purification unit in the air duct communicated with the air outlet, and then the air is discharged from the air outlet of the indoor unit, so that the pollutant in the indoor air is purified, the air quality of the air discharged from the air outlet of the indoor unit is guaranteed, and when the air is introduced from the air inlet of the outdoor air inlet pipe connected with the indoor unit, the air can also be purified through the purification unit in the air duct communicated with the air outlet, and then the air is discharged from the air outlet of the indoor unit, so that the air quality of fresh air discharged from the outdoor can be guaranteed. The above process will be described in detail with reference to fig. 3.
Fig. 3 is a flowchart illustrating a control method of an air conditioning apparatus according to a third embodiment of the present application.

Step 302, determining whether the pollutant concentration of the air quality indication is greater than a threshold value, if so, executing step 304, and if not, executing step 303.
Step 303, do nothing.
The execution of steps 301 to 303 may be referred to the execution of steps 101 to 102 in the above embodiment, and will not be described herein.

When the fresh air mode is executed, air is fed from the air inlet of the outdoor air inlet pipe connected with the indoor unit, air can be purified through the purifying unit in the air duct communicated with the air outlet of the indoor unit, and then the air is discharged from the air outlet of the indoor unit, so that the air quality of fresh air fed indoors outdoors can be ensured.
