Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the related art, the humidifying function of the air conditioner generally requires humidifying the indoor air by means of a wet film or ultrasonic oscillation through a humidifying water tank. The ultrasonic humidifying scheme generates liquid drops to be scattered into the air through ultrasonic high-frequency oscillation, and then the liquid drops are evaporated, so that the air humidifying effect is achieved. The limitation of the technical principle of the ultrasonic humidifying device leads mineral salts and the like in water to be easily diffused into the air along with humidifying water vapor in the ultrasonic humidifying process, so that the indoor air is polluted. The better solution is to use ultrapure water for humidification, but ordinary families do not have the condition, and ordinary mineral water, pure water or even tap water is often used, so that the problem of indoor pollution is more serious. The wet film humidification scheme is humidified through the mode of wet film water absorption evaporation, generally evaporated is water, the problem of particulate pollutants does not exist, the safety is relatively high, but after water quality is polluted by microorganisms, the microorganism aerosol is easy to float to the air along with the evaporation of water vapor to cause indoor pollution. In a word, the humidification safety of the air conditioner is not concerned by the industry, and in the humidification process of the air conditioner, because the water quality problem causes the concentration of indoor pollutants to be increased in the humidification process, the safety of human activities is influenced.
The invention provides a control method of an air conditioner. The air conditioner has a humidifying function. For example, the air conditioner has an ultrasonic humidifying device and/or a wet mold humidifying device, and can realize a humidifying function.
Fig. 1 is a method schematic diagram of an embodiment of a control method of an air conditioner provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes step S110, step S120, step S130, and step S140.
Step S110, detecting whether the humidity value of the environment where the air conditioner is located is smaller than a preset humidity threshold value.
Specifically, when the air conditioner is powered on and operated, the humidity RH of the environment where the air conditioner is located is detected in real time or at regular time, and whether the current humidity RH of the environment where the air conditioner is located is smaller than a preset humidity threshold RH or not is judged 0 . Alternatively, the humidity value of the environment in which the air conditioner is located may be detected by the environmental parameter detection means. The environment parameter detection device can be arranged in an air duct communicated with an air inlet and an air outlet of the air conditioner. The environmental parameter detection means may for example comprise a humidity sensor.
The preset humidity threshold RH 0 In particular, it may be a preset minimum comfort humidity value or a preset (e.g. user preset) maximum comfort humidity valueThe humidity value of (a). The preset humidity threshold RH 0 The range of values of (a) may specifically include 30% to 70%.
And step S120, when the humidity value of the environment where the air conditioner is located is detected to be smaller than a preset humidity threshold value, controlling the air conditioner to operate a humidification mode according to a first preset operation parameter.
In particular, when RH is set 0 When RH is less than or equal to RH, the air humidity of the environment meets the requirement of current comfort, humidification is not needed, and the air conditioner normally operates in a current set mode. When RH is equal to<RH 0 And when the air conditioner is controlled to operate the humidification mode according to a first preset operation parameter, the humidification mode is operated.
The first preset operation parameter may specifically include at least one of a humidification rate k1 (in g/h) and a humidification time t1 (in h). In a specific embodiment, the first preset operation parameter is defined by a current humidity RH and a preset humidity threshold RH as a target humidity 0 Difference value of (RH) 0 -RH) size. The first preset operation parameter can be specifically determined according to the humidity difference between the target humidity and the current humidity of the environment, and the humidification quantity is adjusted by controlling the humidification rate and the humidification time, so that the humidity of the environment reaches the target humidity. The humidification rate is a set value or the humidification time is a set value, for example, the humidification rate is a first set humidification rate. For example, the humidification rate may be set by a user (e.g., more than two humidification rates are provided and selected by the user), and the humidification time is determined by the set humidification rate (the first set humidification rate) and the humidity difference between the target humidity and the current humidity of the environment. For another example, the user sets the humidification time, and the humidification rate is determined by the set humidification time and the humidity difference between the target humidity and the current humidity of the environment. Specifically, f1 (RH) 0 -RH) ═ k1 × t1, where f1 (RH) 0 RH) is the difference in humidity (in g/kg) between the target humidity and the current humidity of the environment in which it is located, the humidity being absolute, the humidity of the environment in which it is located (relative humidity) being the same as the air temperatureIn the same moisture content, the relative humidity changes with changing temperature.
In one embodiment, the humidification rate k1 may be adjusted by the ultrasonic atomization power w, the ultrasonic oscillation frequency v, and/or the blower revolution r (i.e., the humidification blower rate), i.e., k1 ═ f (w, v, r). For example, k1 k 'w r, k' is a constant (which can be obtained experimentally), i.e. by adjusting the ultrasonic atomization power w and/or the ultrasonic oscillation frequency v and/or the blower revolution r, the desired humidification rate is obtained.
The number of revolutions r of the fan (number of revolutions per unit time, i.e., humidification air supply rate) may specifically be the number of revolutions of the humidification fan. The humidifying device of the air conditioner can share an inner fan with the air conditioner to serve as a humidifying fan, or the humidifying device of the air conditioner is provided with an independent humidifying fan.
Step S130, when the air conditioner is controlled to operate in the humidification mode according to a first preset operation parameter, whether the pollutant concentration of the environment where the air conditioner is located is larger than or equal to a preset concentration threshold value or not is detected.
Specifically, detecting the concentration C of indoor pollutants where the air conditioner is located in real time or at regular time, and judging whether the current concentration C of the pollutants is greater than or equal to a preset concentration threshold value C 0 . Alternatively, the pollutant concentration of the environment in which the air conditioner is located may be detected by an air quality detection device. The air quality detection device can be arranged in an air duct communicated with an air inlet and an air outlet of the air conditioner. The contaminant concentration may specifically comprise a concentration of particulate contaminants (e.g. PM2.5, PM0.3) and/or harmful microorganisms (e.g. bacteria, viruses). The air quality detection means may for example comprise a concentration detection sensor for particulate pollutants (e.g. PM2.5, PM0.3) and/or a concentration detection sensor for harmful microorganisms (e.g. bacteria, viruses).
Preset concentration threshold value C 0 Particularly the maximum pollutant concentration for ensuring the activity safety of indoor personnel. The value range of the preset concentration threshold may be, for example: the value range of the preset concentration threshold value corresponding to the particle pollutants is as follows: 0<C 0 Not more than 0.03mg/m3, and/or the value range of the preset concentration threshold value corresponding to the harmful microorganismThe enclosure is as follows: 0<C 0 ≤1000CFU/m3。
And step S140, when the pollutant concentration of the environment where the air conditioner is located is detected to be greater than or equal to a preset concentration threshold value, controlling the air conditioner to stop operating the humidification mode and/or operate the purification mode according to a second preset operation parameter.
Specifically, when the pollutant concentration is less than a preset concentration threshold (C)<C 0 ) And when the air conditioner is used, the situation that the indoor pollutants are not increased in the current humidification process is shown, the health of indoor personnel is not influenced, and the air conditioner can continuously operate according to the current operation parameters. When the concentration of the pollutant is more than or equal to the preset concentration threshold value (C) 0 C) is not more than C), explain that current humidification process leads to indoor pollutant concentration to increase easily, cause very big influence to the indoor activity personnel security of place environment, then can the shutdown (close) humidification mode and/or control air conditioner according to the second and predetermine operating parameter operation humidification mode and/or operation purification mode to avoid the humidification to cause indoor pollution to influence indoor personnel healthy.
In one embodiment, when the contaminant concentration is greater than or equal to a predetermined concentration threshold (C) 0 C) is not more than C), the humidifying mode is closed, and the continuous increase of the concentration of indoor pollutants caused by humidification is avoided. Optionally, the air conditioner further has a purification device. Purifier is used for purifying indoor air, contains at least one of anion purifier, plasma purifier, HEPA net, IFD purifier, electrostatic precipitator device, ultraviolet UV purifier. The purification mode can be operated while the humidification mode is stopped, and pollutants generated by humidification can be purified in time.
In another embodiment, when the contaminant concentration is greater than or equal to a predetermined concentration threshold (C) 0 C) is not more than C), the air conditioner is controlled to operate the humidifying mode according to the second preset operation parameter, so that the pollutant increasing rate can be reduced, the pollutant increasing rate is maintained below a safety threshold value, and the comfort of the air conditioner can be improved on the premise of ensuring the safety of indoor health.
The second preset operation parameters comprise a humidification rate k2 and/or a humidification time t2 and the like, and are subjected to the current humidity RH' and the targetHumidity RH 0 Difference (RH) 0 -RH'), i.e. f2 (RH) 0 -RH') ═ k2 × t 2. In one embodiment, the second preset operation parameter is determined according to the temperature of the environment and the pollutant concentration, and is determined by combining the humidity difference between the humidity of the environment and the target humidity, and the second preset operation parameter is adjusted by controlling the humidification rate and the humidification time. Further, the humidification rate k2 is related to the current pollutant concentration C and the safety threshold C 0 Difference (C-C) 0 ) Size dependent, i.e. k2 ═ f3 (C-C) 0 ) The ultrasonic atomization power w, the ultrasonic oscillation frequency v, and the fan rotation number r (the rotation number per unit time, i.e., the humidification air blowing rate) are adjusted, i.e., k2 is f (w, v, r). For example, when C 0 K2 ═ k1, k1, i.e. the first set humidification rate k1,; when C is 0 C, k2 ═ k2 ', where k2 ' is the second set humidification rate, which is less than the first set humidification rate, i.e., k2 ' < k 1.
Optionally, the air conditioner further has a purification device. Purifier is used for purifying indoor air, contains at least one of anion purifier, plasma purifier, HEPA net, IFD purifier, electrostatic precipitator device, ultraviolet UV purifier. The air conditioner is controlled to operate the humidifying mode according to the second preset operation parameter, and simultaneously, the air conditioner can also operate the purifying mode to timely purify pollutants generated by humidification, so that the concentration of the pollutants is maintained below a safety threshold value, and the comfort of the air conditioner is improved on the premise of ensuring the safety of indoor health.
In a further embodiment, the air conditioner further has a purification device. Purifier is used for purifying room air, contains at least one of anion purifier, plasma purifier, HEPA net, IFD purifier, electrostatic precipitator device, ultraviolet UV purifier. When the concentration of the pollutant is more than or equal to the preset concentration threshold value (C) 0 C) or less, controlling the air conditioner to synchronously operate the purification mode so as to avoid indoor pollution caused by humidification from influencing the health of indoor personnel. By operating the purification mode while operating the humidification mode, the pollutants generated by humidification can be purified in time, so that the concentration of the pollutants is maintained below a safety threshold value to ensure that the chamber is protectedThe comfort of the air conditioner is improved on the premise of internal health safety.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the control method of the air conditioner according to an embodiment of the present invention.
Fig. 2 is a schematic method diagram of an embodiment of a method for controlling an air conditioner according to the present invention. As shown in fig. 2, the air conditioner is powered on to operate, and the humidity RH of the environment where the air conditioner is located is detected in real time or at regular time through the environment parameter detection device. Judging whether the current humidity RH of the environment is less than a preset humidity threshold RH or not 0 . When RH is equal to 0 When RH is less than or equal to, show that indoor air humidity satisfies current travelling comfort demand, need not to carry out the humidification, the air conditioner normal operating current set mode can. When RH is equal to<RH 0 And the humidification control module is used for controlling the air conditioner to operate the humidification mode according to a first preset operation parameter. Detecting the concentration C of the indoor pollutants in real time or at regular time through an air quality detection device, and judging whether the concentration C of the current pollutants is more than or equal to a preset concentration threshold value C 0 . When C is<C 0 And when the air conditioner is used, the situation that the indoor pollutants are not increased in the current humidification process is shown, the health of indoor personnel is not influenced, and the air conditioner can continuously operate according to the current operation parameters. When C is present 0 When C is less than or equal to C, it explains that the current humidification process leads to indoor pollutant concentration to increase easily, causes very big influence to indoor activities personnel security, need close the humidification mode or control air conditioner and predetermine operating parameter operation humidification mode according to the second to avoid the humidification to cause indoor pollution to influence indoor personnel healthy.

Fig. 3 is a schematic method diagram of another embodiment of the method for controlling an air conditioner according to the present invention. As shown in fig. 3, the air conditioner is powered on to operate, and the humidity RH of the environment where the air conditioner is located is detected in real time or at regular time through the environment parameter detection device. Judging whether the current humidity RH of the environment is less than the preset valueSet humidity threshold RH 0 . When RH is equal to 0 When RH is less than or equal to, it shows that the indoor air humidity meets the current comfort requirement, no humidification is needed, and the air conditioner normally operates in the current setting mode. When RH is measured<RH 0 And the humidification control module is used for controlling the air conditioner to operate the humidification mode according to a first preset operation parameter. And detecting the concentration C of the indoor pollutants in real time or at regular time through an air quality detection device. Judging whether the current pollutant concentration C is more than or equal to a preset concentration threshold value C 0 . When C is present<C 0 And when the air conditioner is used, the situation that the indoor pollutants are not increased in the current humidification process is shown, the health of indoor personnel is not influenced, and the air conditioner can continuously operate according to the current operation parameters. When C is present 0 When C is less than or equal to C, it is described that the current humidification process easily leads to the increase of the concentration of indoor pollutants, causes great influence on the safety of indoor activity personnel, and the synchronous operation purification mode of the air conditioner needs to be controlled so as to avoid the humidification to cause indoor pollution to influence the health of the indoor personnel.

Fig. 4 is a block diagram of an embodiment of a control device of an air conditioner according to the present invention. As shown in fig. 4, the control device 100 includes a control unit 110 and a first detection unit 120.
The control unit 110 is configured to control the air conditioner to operate according to a first preset operation parameter. The first detecting unit 120 is configured to detect whether a pollutant concentration of an environment where the air conditioner is located is greater than or equal to a preset concentration threshold when the control unit 110 controls the air conditioner to operate in the humidification mode according to a first preset operating parameter.
Optionally, as shown in fig. 4, the control device 100 further includes a first detecting unit 130, configured to detect whether a humidity value of an environment where the air conditioner is located is smaller than a preset humidity threshold; the control unit 110 is further configured to control the air conditioner to operate the humidification mode according to a first preset operation parameter when the first detection unit detects that the humidity value of the environment where the air conditioner is located is smaller than a preset humidity threshold.
Specifically, when the air conditioner is powered on and operated, the first detection unit 130 detects the humidity RH of the environment where the air conditioner is located in real time or at regular time, and determines whether the current humidity RH of the environment is smaller than the preset humidity threshold RH 0. Alternatively, the humidity value of the environment in which the air conditioner is located may be detected by the environmental parameter detection means. The environment parameter detection device can be arranged in an air duct communicated with an air inlet and an air outlet of the air conditioner. The environmental parameter detection means may for example comprise a humidity sensor.
The preset humidity threshold RH 0 Specifically, the minimum comfort humidity value or the best comfort humidity value may be preset (e.g., preset by a user). The value range of the preset humidity threshold RH0 may specifically include 30% to 70%.
When RH is equal to 0 When RH is less than or equal to RH, the air humidity of the environment meets the requirement of current comfort, humidification is not needed, and the air conditioner normally operates in a current set mode. When RH is equal to<RH 0 When the air humidity of the environment is low, the current comfort requirement is not met, the humidification mode needs to be operated to improve the air humidity and ensure the comfort of the environment, and then the control unit 110 controls the air conditioner to operate the humidification mode according to the first preset operation parameter.
The first preset operation parameter may specifically include at least one of a humidification rate k1 (unit g/h) and a humidification time t1 (unit h). In one specific embodiment, the first predetermined operating parameter is influenced by the magnitude of the difference (RH0-RH) between the current humidity RH and a predetermined humidity threshold RH0 as the target humidity. The first preset operation parameter can be specifically determined according to the humidity difference between the current humidity and the target humidity of the environment, and the humidification quantity is adjusted by controlling the humidification rate and the humidification time, so that the humidity of the environment reaches the target humidity. The humidification rate is a set value or the humidification time is a set value, for example, the humidification rate is a first set humidification rate or the humidification time is a first set humidification time. For example, the humidification can be set by a user, for exampleThe humidification time is determined by the set humidification rate and the humidity difference between the target humidity and the current humidity of the environment. For another example, the user sets the humidification time, and the humidification rate is determined by the set humidification time and the humidity difference between the target humidity and the current humidity of the environment. Specifically, f1 (RH) 0 -RH) ═ k1 × t1, where f1 (RH) 0 RH) is the change of the moisture content (unit g/kg) before and after, and is temperature-dependent, the moisture content is absolute, and the ambient air humidity (relative humidity) is related to the air temperature, and under the same moisture content, the relative humidity can be changed when the temperature is changed.
In one embodiment, the humidification rate k1 may be adjusted by the ultrasonic atomization power w, the ultrasonic oscillation frequency v, and/or the blower revolution r (i.e., the humidification blower rate), i.e., k1 ═ f (w, v, r). In particular, k ═ k '× w × r, k' is a constant, i.e. the desired humidification rate is obtained by adjusting the ultrasonic atomization power w and/or the ultrasonic oscillation frequency v and/or the fan revolutions r.
The number of revolutions r of the fan (i.e., the humidification air supply rate) may specifically be the number of revolutions of the humidification fan. The humidifying device of the air conditioner can share an inner fan with the air conditioner to be used as a humidifying fan, or the humidifying device of the air conditioner is provided with an independent humidifying fan.
When the control unit 110 controls the air conditioner to operate in the humidification mode according to a first preset operation parameter, the first detection unit 120 detects whether the pollutant concentration of the environment where the air conditioner is located is greater than or equal to a preset concentration threshold; when the first detection unit detects that the pollutant concentration of the environment where the air conditioner is located is greater than or equal to the preset concentration threshold, the control unit 110 controls the air conditioner to stop operating the humidification mode and/or operate the purification mode according to a second preset operation parameter.
Specifically, the first detection unit 120 detects the concentration C of the indoor pollutant where the air conditioner is located in real time or at regular time, and determines whether the current pollutant concentration C is greater than or equal to a preset concentration threshold C 0 . Alternatively, the first detection unit 120 may detect the air conditioner through an air quality detection deviceThe concentration of contaminants in the environment. The air quality detection device can be arranged in an air duct communicated with an air inlet and an air outlet of the air conditioner. The contaminant concentration may specifically comprise a concentration of particulate contaminants (e.g. PM2.5, PM0.3) and/or harmful microorganisms (e.g. bacteria, viruses). The air quality detection means may for example comprise a concentration detection sensor for particulate pollutants (e.g. PM2.5, PM0.3) and/or a concentration detection sensor for harmful microorganisms (e.g. bacteria, viruses).
Preset concentration threshold value C 0 Particularly the maximum pollutant concentration for ensuring the activity safety of indoor personnel. The value range of the preset concentration threshold may be, for example: the value range of the preset concentration threshold value corresponding to the particle pollutants is as follows: 0<C 0 Not more than 0.03mg/m3, and/or the value range of the preset concentration threshold value corresponding to the harmful microorganism is as follows: 0<C 0 ≤1000CFU/m3。
When the concentration of the pollutant is less than a preset concentration threshold value (C)<C 0 ) And when the air conditioner is used, the situation that the indoor pollutants are not increased in the current humidification process is shown, the health of indoor personnel is not influenced, and the air conditioner can continuously operate according to the current operation parameters. When the concentration of the pollutant is greater than or equal to a preset concentration threshold value (C) 0 C) is not more than C), explain that current humidification process leads to indoor pollutant concentration to increase easily, causes very big influence to the indoor activity personnel security of place environment, then can the bring to rest (close) humidification mode and/or control air conditioner according to the second and predetermine operating parameter operation humidification mode and/or operation purification mode to avoid the humidification to cause indoor pollution to influence indoor personnel healthy.
In one embodiment, when the contaminant concentration is greater than or equal to a predetermined concentration threshold (C) 0 C) is not more than C), the humidifying mode is closed, and the continuous increase of the concentration of indoor pollutants caused by humidification is avoided. Optionally, the air conditioner further has a purification device. Purifier is used for purifying indoor air, contains at least one of anion purifier, plasma purifier, HEPA net, IFD purifier, electrostatic precipitator device, ultraviolet UV purifier. The humidifying mode can be stopped and the purifying mode can be operated at the same time, so that the operation is timelyPurifying the pollutants generated by humidification.
In another embodiment, when the contaminant concentration is greater than or equal to a predetermined concentration threshold (C) 0 C) is not more than C), the air conditioner is controlled to operate the humidifying mode according to the second preset operation parameter, so that the pollutant increasing rate can be reduced, the pollutant increasing rate is maintained below a safety threshold value, and the comfort of the air conditioner can be improved on the premise of ensuring the safety of indoor health.
The second preset operation parameters comprise a humidification rate k2 and/or a humidification time t2 and the like, and are subjected to the current humidity RH' and the target humidity RH 0 Difference (RH) 0 -RH'), i.e. f1 (RH) 0 -RH') -k 2 t 2. In one embodiment, the second preset operation parameter is determined according to the temperature of the environment and the pollutant concentration, and is determined by combining the humidity difference between the humidity of the environment and the target humidity, and the second preset operation parameter is adjusted by controlling the humidification rate and the humidification time. Furthermore, the humidification rate k2 is related to the current pollutant concentration C and the safety threshold C 0 Difference (C-C) 0 ) Size dependent, i.e. k2 ═ f2 (C-C) 0 ) The ultrasonic atomization power w, the ultrasonic oscillation frequency v, the blower rotation number r (i.e., the humidification blowing rate), and other parameters are used to adjust, that is, k2 is f (w, v, r). For example, when C 0 When the humidification rate is larger than C, k2 is k1, and k1 is the first set humidification rate k 1; when C is present 0 C, k2 ═ k2 ', where k2 ' is the second set humidification rate, which is less than the first set humidification rate, i.e., k2 ' < k 1.
Optionally, the air conditioner further has a purification device. Purifier is used for purifying indoor air, contains at least one of anion purifier, plasma purifier, HEPA net, IFD purifier, electrostatic precipitator device, ultraviolet UV purifier. The air conditioner is controlled to operate the humidification mode according to the second preset operation parameter, and simultaneously, the purification mode can be operated, pollutants generated by humidification can be purified timely, the concentration of the pollutants is maintained below a safety threshold value, and the comfort of the air conditioner is improved on the premise that the safety of indoor health is guaranteed.

When the concentration of the pollutant is greater than or equal to a preset concentration threshold value (C) 0 C) or less, the control unit 110 controls the air conditioner to synchronously operate the purification mode so as to avoid indoor pollution caused by humidification from affecting the health of indoor personnel. Through the purification mode of operation when the operation humidification mode, the pollutant that the humidification produced can in time be purified, makes pollutant concentration maintain under the safe threshold to improve the air conditioner travelling comfort under the prerequisite of guaranteeing indoor health security.
