Referring to fig. 2, the present invention provides a first embodiment of a control method of an air conditioner, including the steps of:
step S10, after the air conditioner starts the purification mode, detecting the environmental parameters of the environment where the air conditioner is located in real time or at regular time, wherein the environmental parameters comprise at least one of an environmental temperature value and an environmental humidity value;
the embodiment operates in an air conditioner, wherein the air conditioner can be an air conditioner or an air purifier; it is understood that the present embodiment may also be operated in a control device of an air conditioner, such as a mobile terminal or the like.
It is understood that the air conditioner may be a device in which a user manually turns on its cleaning mode, for example, when receiving a turn-on command triggered by the user, the air conditioner cleaning mode is turned on; or automatically starting, for example, when the indoor environmental pollutants reach a certain concentration, the purification mode of the air conditioner is automatically started to purify the indoor air.
Specifically, when the air conditioner is in a standby state, the pollutant concentrations of various pollutants in the room where the air conditioner is located are detected at regular time;
and when the pollutant concentration is greater than or equal to a preset safety threshold value, starting the air conditioner, wherein the preset safety threshold value is less than a national standard safety threshold value.
The corresponding relation between each pollutant and the corresponding preset safety threshold is preset, when the pollutant concentration is compared with the corresponding preset safety threshold, and when the concentration of one pollutant is greater than the corresponding preset safety threshold, the pollutant concentration of the current indoor environment possibly has certain harm to a human body, and thus, the air conditioner is automatically started to carry out air conditioning. In this embodiment, the preset safety threshold corresponding to each pollutant is smaller than the international safety threshold, for example, according to the specification of the indoor air quality standard GB/T18883-2002, the formaldehyde concentration is 0.1mg/m3, the benzene concentration is 0.11mg/m3, the NO2 concentration is 0.24mg/m3, the PM10 concentration is 0.15mg/m3, and the TVOC concentration is 0.6mg/m3, in this embodiment, the safety thresholds may be set as follows: formaldehyde concentration 0.07mg/m3, benzene concentration 0.077mg/m3, NO2 concentration 0.168mg/m3, PM10 concentration 0.105mg/m3, TVOC concentration 0.42mg/m 3. The setting predetermine safety threshold and be less than national standard safety threshold's aim at air conditioner needs certain time at the in-process of regulation, just open air conditioner and adjust after indoor pollutant concentration reaches national standard safety threshold, it is continuous to give off based on pollutant concentration, when waiting to reduce pollutant concentration to national standard safety threshold, indoor pollutant concentration has caused harm to the human body in a period of time, consequently, it is less than national standard safety threshold to set up predetermined safety threshold, open air conditioner regulation air in advance, guarantee that indoor pollutant concentration is below national standard safety threshold always, guarantee that air conditioner's regulation effect reaches the best.
The specific setting is that when the concentration of the pollutants of at least one pollutant is detected to be higher than a preset safety threshold value, the purification mode of the air conditioner is automatically started, and the absolute safety of the indoor environment is ensured. It can be understood that the weights of various pollutants can be set according to the user requirements, when the pollutant concentration of the pollutant with high weight is detected to be greater than a preset safety threshold value, the air conditioner is started, and the purification mode of the air conditioner is started only when the pollutant with high weight is higher, so that the pollutants which have great influence on the human body are mainly removed, and thus, the energy is saved.
The pollutants purified by the embodiment mainly comprise formaldehyde, benzene series, VOC, NOX, particulate matters and the like, the filter screen adopted by the adopted purifying part can be an HEPA (particulate matter removal) net and an active carbon net or a composite net (the composite net is formed by processing and compounding the HEPA net and active carbon particles), tests show that the environment temperature and humidity have great influence on the purifying efficiency or purifying capacity of the HEPA net (particulate matter removal) net and the active carbon net or the composite net, for example, humidity (water vapor) has influence on electrostatic interception of the particulate matters, the active carbon filter screen adsorbs gaseous pollutants by utilizing a developed gap structure in the active carbon filter screen and stores the gaseous pollutants in the meshes, if the environment temperature is slightly or excessively high, the trapped gaseous pollutants in the active carbon are easy to desorb and escape to cause secondary pollution, so when the gaseous pollutants are purified, the temperature (high temperature) has influence on the adsorbing capacity of the active carbon, therefore, in order to prevent to purify the in-process, indoor environmental parameter influences the life-span and the purification efficiency that purify the filter screen, this embodiment is after opening purification performance, and real-time or regularly detect the environmental parameter of place environment, specifically can be at the indoor temperature sensor and the humidity transducer that set up in place to real-time or regularly gather indoor ambient temperature value and environment humidity value.
And step S20, when the environmental parameter is larger than a first preset threshold value, adjusting the operating parameter of the air conditioner to adjust the environmental parameter of the environment, wherein the purifying capacity of the filter material in the air conditioner when the environmental parameter is larger than the first preset threshold value is smaller than the purifying capacity when the environmental parameter is smaller than or equal to the first preset threshold value.
The first preset threshold comprises at least one of a first temperature preset threshold and a first humidity preset threshold, and when the detected environmental parameter is an environmental temperature value, whether the environmental temperature value is greater than the first temperature preset threshold is judged; and when the detected environmental parameter is an environmental humidity value, judging whether the environmental humidity value is greater than the first humidity preset threshold value. The first preset temperature threshold is a temperature critical value which can be borne by a filter screen in the current air conditioner, and is specifically different according to different filter screens, and in the embodiment, the first preset temperature threshold is set to be 20-28 ℃, and preferably 24 ℃; the first humidity preset threshold is a humidity critical value that a filter screen in the air conditioner can bear at present, and is different according to different adopted filter screens, and in this embodiment, the first humidity preset threshold is set to be 25% to 40%, preferably 30%.
When environmental parameter is greater than first predetermined threshold value, because the filter media is in among the air conditioner environmental parameter is greater than the purification capacity when first predetermined threshold value is less than the purification capacity when environmental parameter is less than or equal to first predetermined threshold value, it has an influence to air conditioner's filter screen and purification efficiency to judge current environment, in order to ensure the safe handling of filter screen, guarantees purification efficiency, when needing to purify, adjusts the environmental parameter of place environment, like adjusting ambient temperature value and environmental humidity value, can specifically realize environmental parameter's regulation through the operating parameter who adjusts air conditioner, wherein, air conditioner's operating parameter includes compressor frequency, fan rotational speed etc..
The step of adjusting the operating parameter of the air conditioner to adjust the environmental parameter of the environment includes:
the cooling function of the air conditioner is turned on, and/or the dehumidifying function of the air conditioner is turned on, to adjust the environmental parameters of the room.
If a refrigerating device and a dehumidifying device (such as an air conditioner) are arranged in the air conditioner, when the environmental parameter is greater than a first preset threshold value, the refrigerating function of the refrigerating device of the air conditioner is directly started to reduce the indoor environment temperature value, or the dehumidifying function of the dehumidifying device of the air conditioner is started to reduce the indoor environment humidity value.
If the air conditioner does not have a cooling device and a dehumidifying device (such as a purifier), the step of adjusting the operating parameters of the air conditioner to adjust the environmental parameters of the environment comprises: and sending a regulating instruction to other air conditioning equipment in the same environment with the air conditioner so as to enable the other air conditioning equipment to enter an operating state and regulate the environmental parameters of the environment. The other air conditioning equipment may specifically include at least one of a refrigeration equipment and a dehumidification equipment, that is, when the environmental parameter is greater than a first preset threshold value, an adjustment instruction is sent to the indoor refrigeration equipment to operate a refrigeration function of the refrigeration equipment to adjust the indoor environmental parameter, and/or an adjustment instruction is sent to the indoor dehumidification equipment to operate a dehumidification function of the dehumidification equipment to adjust the indoor environmental parameter. The linkage of household appliances is realized in a network or electric signal mode, and when the current indoor environment is unfavorable for the use of a filter screen and the purification efficiency is low in the purification process of the air conditioner, other household appliances are controlled to be started based on the linkage of the household appliances, such as the refrigeration of an air conditioner, the dehumidification of a dehumidifier and the like, so as to adjust the indoor environment parameters.
It can be understood that, while meeting the requirement of the air conditioner for safe use environment, in order to ensure indoor comfort, after the step of adjusting the operating parameters of the air conditioner to adjust the environmental parameters of the environment, the method further comprises: and when the environmental parameter is less than or equal to the first preset threshold value, the refrigeration function of the air conditioner is turned off, and/or the dehumidification function of the air conditioner is turned off.
Also when the indoor environment reaches air conditioner's safe handling environment requirement, close air conditioner's refrigeration function, or dehumidification function, prevent that air conditioner from refrigerating or dehumidifying always, lead to the indoor environment comfort poor, influence user experience, also play energy-conserving effect simultaneously.
In other embodiments, the environmental parameter of the environment in which the air conditioner is located may also be detected by other air monitoring devices in the same environment as the air conditioner, for example, other air detecting devices in the environment in which the air conditioner is located are electrically connected to the air conditioner, in this embodiment, the step of detecting the environmental parameter of the environment in which the air conditioner is located in real time or at regular time includes:
sending an environmental parameter detection data request to other air monitoring devices in the same environment as the air conditioner;
receiving the environmental parameters returned by the other air conditioning equipment.
After receiving the environment parameter detection data request sent by the air conditioner, the other air monitoring devices detect the indoor environment temperature value and/or indoor environment humidity value, and return the detected environment parameter value to the air conditioner for reference.
In this embodiment, after air conditioner started the purification mode, through the environmental parameter of real-time or regularly detecting air conditioner place environment, like ambient temperature value and environmental humidity value when environmental parameter is greater than first preset threshold value, air conditioner's operating parameter is adjusted to adjust the environmental parameter of place environment, like reduce ambient temperature and ambient humidity, in order to protect the filter screen, ensure the life and the purification efficiency of filter screen, thereby improve air conditioner's purifying effect.
Referring to fig. 3, the present invention provides a second embodiment of a control method of an air conditioner, based on the embodiment of fig. 2, after the step of starting the purification function of the air conditioner, the control method of the air conditioner further includes:
step S30, detecting the current pollutant concentration of various pollutants in the room where the air conditioner is located in real time;
after the air conditioner is started, the gas sensor and the particulate matter sensor are controlled to monitor the current pollutant concentration of various indoor pollutants in real time, wherein the pollutants mainly comprise formaldehyde, benzene series, VOC, NOX, particulate matters and the like.
Step S40, acquiring the target pollutant with the current pollutant concentration greater than a preset safety threshold;
when the concentration of each pollutant is detected, a preset safety threshold value which is larger than the corresponding pollutant is obtained, the pollutant concentration of each pollutant is compared with the corresponding preset safety threshold value, and the target pollutant which is larger than the preset safety threshold value is screened, wherein the preset safety threshold value is smaller than a national standard safety threshold value.
Step S50, determining the target purification efficiency of the air conditioner according to the current pollutant concentration, pollutant emission rate and preset safety threshold value corresponding to the target pollutant;
and step S60, determining the target rotating speed of the fan of the air conditioner according to the target purifying efficiency.
And calculating the purification amount of the air conditioner based on the consideration that the current pollutant concentration corresponding to the target pollutant and the concentration generated based on the pollutant emission rate are lower than a preset safety threshold value, and further calculating the target purification efficiency of the air conditioner based on the purification amount within a fixed time.
And step S70, controlling the fan of the air conditioner to operate according to the target rotating speed.
Based on the continuous emission of pollutants, the air conditioner is adjusted in advance in order to predict the concentration of the pollutants in advance, so that the pollutants are purified while being emitted, the indoor temperature is continuously maintained below the preset safety threshold value, for the indoor realization of continuously maintaining better air quality, after the target pollutant is determined, when the pollutant concentration in the indoor is lower than the preset safety threshold value based on the current pollutant concentration value and the pollutant emission rate of the target pollutant, the air conditioner needs to provide the purification capacity, and the adjustment of the purification capacity of the air conditioner in this embodiment is realized by adjusting the wind speed of the fan, specifically, the target rotation speed of the fan, and after the target rotation speed of the fan is obtained, and controlling a fan of the air conditioner to operate according to the target rotating speed so as to ensure that the indoor temperature is continuously maintained below a preset safety threshold value.
When the target pollutants have multiple types, the target pollutants used for calculating the target rotating speed can be determined based on the weight of the target pollutants or the preferred sequence set by a user, or the target pollutants used for calculating the target rotating speed can be determined based on the standard-exceeding severity of the target pollutants, or after the target rotating speed of the fan is calculated based on each target pollutant, the average value of each target rotating speed is obtained to adjust the fan of the air conditioner.
The diffusion rate of the pollutants is the diffusion rate of the pollutants from indoor objects, the diffusion rate of the pollutants is possibly different based on different temperatures or humidity, so that when the air conditioner is set to be in a standby state or closed state, the pollutant concentration of the indoor environment is detected at regular time, the diffusion rate of the pollutants is determined, the accurate diffusion rate of the obtained current pollutants is ensured, and the accurate calculation of the target rotating speed of the fan is ensured. Specifically, the control method of the air conditioner includes:

and determining the target purifying air volume according to the target purifying efficiency and the clean air volume.
The clean air quantity is the air quantity of clean air generated in the air passing through the filter screen in unit time, the clean air quantity is related to the air quantity of the air conditioner and the purification efficiency, the ratio of the clean air quantity to the air quantity of the air conditioner is the purification efficiency of the air conditioner, the target purification air quantity is calculated by adopting Q60V [ (lnd1-lnd 2)/delta t ]/eta based on the relation between the clean air quantity and the air quantity, wherein d1 and d2 are the indoor pollutant concentrations at the time interval of Δ t after the cleaning function is started (i.e. the pollutant concentration at the first time point is d1, the pollutant concentration at the second time point is d2, and the time interval between the first time point and the second time point is Δ t), and calculating the target rotating speed according to the corresponding relation between the air volume and the rotating speed of the fan, wherein the relation between the air volume and the rotating speed of the fan is Q ═ f (n).
In summary, this embodiment exemplifies the calculation of the target rotation speed of one of the pollutants, such as formaldehyde, and the formaldehyde emission rate v ═ b-a)/(t2-t1 from the indoor formaldehyde pollution source; formaldehyde safety threshold 0.07mg/m 3; the current air volume is Q, and the current formaldehyde concentration is c mg/m 3; where V is the current indoor volume, Q is the current purified air volume, n is the number of fan revolutions, and specifically, the correspondence Q between the number of fan revolutions n and the air volume is f (n).
Firstly, in order to ensure that the indoor environment is always below a preset safety threshold, the purification amount of the air purifier is calculated by adopting v T + c-eta T ═ 0.07.
The method comprises the steps of obtaining the accumulated concentration of a preset time interval T according to the current concentration C of formaldehyde and the emission rate v of the formaldehyde, obtaining the purification amount of the air purifier in the preset time interval on the basis that the difference value between the accumulated concentration and the purification amount is required to be smaller than or equal to a preset safety threshold value of 0.07, and calculating the purification efficiency of the air purifier on the basis of the relation between the purification amount and the preset time interval.
The target air volume of the air conditioner is calculated based on the relationship Q of the purification efficiency, the clean air volume and the air volume, 60 × V [ (lnd1-lnd2)/Δ t ]/η, wherein 60 × V [ (lnd1-lnd2)/Δ t ] is a calculation formula of the clean air volume of the air conditioner, and d1 and d2 are the indoor pollutant concentrations at the time interval Δ t after the purification function is turned on, respectively.
Therefore, through the safety threshold value, the pollutant emission rate, the current purification efficiency and the concentration change of unit time delta T, and based on a V T + c- { 60V [ (lnd1-lnd 2)/delta T ] }/Q T ═ 0.07 conversion formula, the rotating speed of the purification fan can be automatically adjusted and the purification air volume can be controlled according to the current pollutant concentration and the purification capacity effectively in real time, so that the concentration of each pollutant is kept below the safety threshold value, the air is continuously ensured to be fresh, and the health of a user is ensured.

Therefore, when the indoor pollutant concentration is detected in real time, the preset safety threshold corresponding to each pollutant is obtained, and the pollutant concentration is compared with the corresponding preset safety threshold.
Step S420, calculating the difference percentage between the current pollutant concentration of each pollutant and the corresponding preset safety threshold;
step S430, the target pollutant with the largest difference percentage is obtained.
When a plurality of detected pollutant concentrations greater than the corresponding preset safety threshold values exist, the fact that the number of pollutants exceeding the standard in the current room is multiple is indicated, and the fan corresponding to the air conditioner can only operate at one target rotating speed, so that the target rotating speed of the fan needs to be calculated by specifically determining the current pollutant concentration corresponding to one target pollutant and the corresponding preset safety threshold value, and after the target pollutant is removed, other target pollutants are purified and removed. The target rotating speed of the fan is calculated according to the current pollutant concentration corresponding to the target pollutant and the corresponding preset safety threshold value, wherein the current pollutant concentration corresponds to the target pollutant, and the standard exceeding degree of the pollutant is determined.

and acquiring the pollutants with the highest priority according to a preset priority.

And sequentially, when the concentration of the formaldehyde is reduced to be below a preset safety threshold, the system preferentially takes the benzene series as the target pollutant and calculates the target rotating speed of the fan by using the benzene series.
