At present, people in China generally get used to tightly close doors and windows when an air conditioner is started so as to ensure the refrigerating or heating effect of the air conditioner, and because the tightly closed doors and windows can lead to the reduction of indoor air quality, the sleeping quality of users is affected, discomfort such as dizziness or listless is easily caused, the indoor air quality can be improved by introducing fresh air at present, but fluctuation of indoor temperature can be caused when the fresh air is introduced, and at the moment, if the host computer of the air conditioner is adjusted blindly to control the room temperature, the problems of energy consumption, noise and the like can be brought.
Aiming at the problems, the embodiment of the application provides a fresh air control method, which can timely adjust the introduction speed of fresh air according to the specific conditions of indoor temperature, outdoor temperature and indoor carbon dioxide concentration, and improve the influence of the fresh air introduced by an air conditioner in a sleep mode on the indoor environment, so that the air conditioner can maintain low-power and low-noise operation and simultaneously meet the requirements of users on indoor comfort.
The following describes the technical scheme of the embodiment of the present application in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flow chart of a fresh air control method in a sleep mode according to an embodiment of the application.
When a general user starts an air conditioner, in order to ensure the indoor refrigerating or heating effect, a door and window can be selected to be tightly closed, meanwhile, the indoor and outdoor air exchange is greatly weakened, the oxygen content in the indoor air is reduced, the carbon dioxide content is increased, when the user starts a sleep mode and a fresh air mode simultaneously, the indoor air quality can be improved by introducing fresh air, but the fluctuation of the indoor temperature can be caused when the fresh air is introduced, in order to balance the fluctuation of the indoor temperature, if the air conditioner host machine is blindly adjusted to control the room temperature, the noise and other problems are caused, in order to balance the air quality and the indoor temperature, the current indoor temperature and the outdoor temperature can be obtained in real time through a temperature sensor, the indoor carbon dioxide concentration is obtained in real time through a carbon dioxide sensor, the measuring range of the carbon dioxide sensor is 400-10000ppm, the measuring precision is +/-50 ppm+3% reading, the environment where the user is located is determined according to the obtained indoor temperature, and the introducing speed of the fresh air is adjusted according to the environment where the user is located.
Step S1, when the current indoor carbon dioxide concentration is monitored to be higher than a concentration threshold value, a fresh air mode is operated at a first wind speed, wherein the concentration threshold value is a preset value, and specifically, the range of the concentration threshold value is 1000ppm-5000ppm; because the carbon dioxide concentration in the air is about 400ppm in a natural state, researches show that when people are at the carbon dioxide concentration of 1000ppm for more than 2.5 hours, the cognitive ability is obviously reduced; headache, somnolence or dullness may occur when people are at a carbon dioxide concentration of 5000ppm; when people are under the carbon dioxide concentration of 10000ppm, light poisoning reaction can occur, so that user comfort can be reduced when the carbon dioxide concentration is higher than 1000ppm, and the carbon dioxide concentration is preferably not higher than 5000ppm at the highest, and it is noted that the carbon dioxide threshold can be set according to practical situations, for example, when the temperature difference between the inside and the outside is small, the value of the carbon dioxide threshold can be smaller, and when the temperature difference between the inside and the outside is large, the value of the carbon dioxide threshold can be larger.
Step S2, after fresh air is introduced at a first wind speed, the fresh air can cause certain fluctuation to the indoor temperature, in order to give consideration to indoor temperature control when fresh air is introduced, whether the current internal and external temperature difference is smaller than a temperature difference threshold value or not can be judged firstly, the internal and external temperature difference is the absolute value of the difference between the indoor temperature and the outdoor temperature, the temperature difference threshold value is a preset value, is specific, the temperature difference threshold value can be set to 4 degrees, if the current internal and external temperature difference is smaller than the temperature threshold value, the difference between the indoor temperature and the outdoor temperature is not large, the introduced fresh air cannot cause larger fluctuation to the indoor temperature, the current running state of the air conditioner is maintained, the fresh air mode is continuously operated at the first wind speed, preferably, the speed of introducing the fresh air and the indoor carbon dioxide concentration are set to be in positive correlation, when the carbon dioxide concentration is increased, otherwise, the speed of introducing the fresh air is reduced when the carbon dioxide concentration is reduced, and the comfort of the quality of the air is dynamically maintained; if the current temperature difference between the inside and the outside is greater than or equal to the temperature threshold, the difference between the indoor temperature and the outdoor temperature is larger, and the introduced fresh air can cause larger fluctuation on the indoor temperature.
Step S3, when the difference between the indoor temperature and the outdoor temperature is large, if the current indoor temperature is smaller than or equal to the outdoor temperature, the air conditioner is in a refrigeration mode generally corresponding to hot summer nights, compared with the temperature reduction, the sensitivity of a user to temperature rise is not so high, and at the moment, the current running state of the air conditioner is maintained, namely, a fresh air mode is operated at a first wind speed; if the current indoor temperature is higher than the outdoor temperature, the sensitivity of the user to temperature decrease is higher than the sensitivity to temperature increase generally at night in cold winter, and the indoor temperature is greatly reduced due to the introduced fresh air, so that the user feels cool or the air conditioning heat effect is not good, and the user experience is influenced easily, and at this time, step S4 is executed.
And S4, stopping running the fresh air mode or running the fresh air mode at a second wind speed, wherein the second wind speed is smaller than the first wind speed.
In the embodiment of the application, after a user starts a sleep mode of the air conditioner, the air conditioner monitors the current indoor temperature and the indoor carbon dioxide concentration in real time; if the current indoor carbon dioxide concentration is monitored to be higher than the concentration threshold value, the outdoor fresh air is introduced in a first air speed operation fresh air mode, because the introduced fresh air can bring certain fluctuation to the indoor temperature, if the air conditioner host computer is blindly adjusted to control the room temperature, the noise and other problems can be brought, the requirements of a user on noise and comfort level in the sleeping process are higher, in order to consider the air quality and the indoor temperature, whether the current internal and external temperature difference is smaller than the temperature difference threshold value is judged, if so, the internal and external temperature difference is smaller, the influence of the introduced fresh air on the indoor temperature is not great, if not, the indoor and external temperature difference is large, the introduced fresh air can cause larger fluctuation to the indoor temperature, at the moment, whether the current indoor temperature is larger than the outdoor temperature is judged, if so, the method for controlling the fresh air provided by the application can adjust the introducing speed of the fresh air in time according to specific conditions of indoor temperature, outdoor temperature and indoor carbon dioxide concentration, and improve the influence of the fresh air introduced by an air conditioner in a sleep mode on indoor environment, so that the air conditioner can maintain low-power and low-noise operation, and simultaneously consider indoor air quality and meet the requirements of users on indoor comfort.
Example two
At night in hot summer, when the temperature difference between the indoor temperature and the outdoor temperature is large, the indoor temperature can be greatly increased due to the introduced fresh air, and when the indoor temperature is too high, a user can feel that heat can be even awakened, so that the comfort is affected.
Referring to fig. 2, fig. 2 is a flow chart of a fresh air control method in a cooling mode and a sleep mode according to an embodiment of the application.
Step S101, based on the first embodiment, if the current indoor carbon dioxide concentration is higher than the concentration threshold, the fresh air mode is operated at the first wind speed, and since the air conditioner is in the cooling mode and the indoor temperature is far lower than the outdoor temperature, the introduced fresh air will greatly raise the indoor temperature, but compared with the temperature decrease, the sensitivity of the user to the temperature increase is not so high, and at this time, the current operation state of the air conditioner is continuously maintained, i.e. the fresh air mode is operated at the first wind speed.
Step S102, along with the introduction of the fresh air, when the indoor temperature is too high, the user may feel hot and even be awakened, thereby affecting comfort, and in order to prevent the indoor temperature from fluctuating too much, determining in real time whether the current indoor temperature is greater than a temperature rise critical value, where the temperature rise critical value includes: user settings and first system settings; the smaller value of the user set value and the first system set value is preferentially selected as a temperature rise critical value, and if the current indoor temperature is smaller than or equal to the temperature rise critical value, the current running state of the air conditioner is maintained, and the fresh air mode is continuously operated at the first wind speed; and if the current indoor temperature is greater than the temperature rise critical value, stopping running the fresh air mode or running the fresh air mode at the second wind speed.
Step S103, when the fresh air mode is stopped or the fresh air mode is operated at the second wind speed, the indoor carbon dioxide concentration is gradually increased, whether the current indoor carbon dioxide concentration is higher than a concentration threshold value is judged in real time, if the current indoor carbon dioxide concentration is higher than the concentration threshold value, the fresh air mode is operated at the first wind speed, and if the current indoor carbon dioxide concentration is lower than or equal to the concentration threshold value, the current operation state of the air conditioner is maintained, namely, the fresh air mode is stopped or the fresh air mode is operated at the second wind speed.
The second wind speed is smaller than the first wind speed, and the user set value is a temperature value set by a user.
In the embodiment of the application, when the internal and external temperature difference between the indoor temperature and the outdoor temperature is large, whether the current indoor temperature is larger than the temperature rise critical value is judged in real time, when the indoor temperature is larger than the temperature rise critical value, the fresh air mode is stopped to operate or is operated at the second wind speed until the current indoor carbon dioxide concentration is higher than the concentration threshold value, and then the fresh air mode is operated at the first wind speed, and the current indoor temperature is controlled to be smaller than or equal to the temperature rise critical value, so that the indoor temperature cannot fluctuate too much while the indoor air quality is improved, and the comfort of a user is improved.
Example III
At night in winter, when the temperature difference between indoor temperature and outdoor temperature is large, the indoor temperature can be greatly reduced due to the introduced fresh air, and when the indoor temperature is too low, users can easily catch a cold or generate illusion of poor air conditioning heat effect, so that the user experience is affected, and the application provides a corresponding scheme for improving the indoor air quality and simultaneously avoiding overlarge fluctuation of the indoor temperature.
Referring to fig. 3, fig. 3 is a flow chart of a fresh air control method in a heating mode and a sleep mode according to an embodiment of the application.
Step S201, based on the first embodiment, if the current indoor carbon dioxide concentration is higher than the concentration threshold, the fresh air mode is operated at the first wind speed.
Step S202, because the air conditioner is in a heating mode, and the indoor temperature is far greater than the outdoor temperature, the introduced fresh air can greatly reduce the indoor temperature, and because the sensitivity of a user to temperature reduction is higher than the sensitivity to temperature increase, if the indoor temperature is too low, the user is easy to catch a cold or generate the illusion that the air conditioner heat effect is poor, thereby influencing the user experience, and in order to ensure that the indoor temperature cannot fluctuate too much, judging in real time whether the current indoor temperature is greater than a temperature reduction critical value, wherein the temperature reduction critical value comprises: user settings and third system settings; and preferably selecting a larger value of the user set value and the third system set value as a temperature drop critical value, if the indoor temperature is greater than the temperature drop critical value, maintaining the current running state of the air conditioner, continuing to run the fresh air mode at the first wind speed, preferably judging the concentration of the indoor carbon dioxide in real time, adjusting the speed of introducing the fresh air according to the concentration of the carbon dioxide until the indoor temperature is less than the temperature drop critical value, and if the indoor temperature is less than or equal to the temperature drop critical value, stopping running the fresh air mode or running the fresh air mode at the second wind speed.
Step S203, when the operation of the fresh air mode is stopped or the fresh air mode is operated at the second air speed, the indoor temperature is gradually increased along with the operation of the air conditioner heating mode, whether the indoor temperature is greater than or equal to a temperature rise critical value is judged in real time, and if the indoor temperature is greater than or equal to the temperature rise critical value, the fresh air mode is operated at the first air speed when the current indoor carbon dioxide concentration is greater than a concentration threshold value; and if the indoor temperature is smaller than the temperature rise critical value, stopping running the fresh air mode or running the fresh air mode at the second wind speed.
It should be noted that, the temperature rise critical value includes: user settings and first system settings; and preferably selecting a smaller value of a user set value and a first system set value as a temperature rise critical value, wherein the second wind speed is smaller than the first wind speed, and the user set value is the temperature set by the user.
In the embodiment of the application, when the internal and external temperature difference between the indoor temperature and the outdoor temperature is large, whether the current indoor temperature is larger than the temperature drop critical value is judged in real time, when the indoor temperature is smaller than or equal to the temperature drop critical value, the fresh air mode is stopped to operate or is operated at the second wind speed until the indoor temperature is returned to the temperature rise critical value, and then the fresh air mode is operated at the first wind speed, so that the indoor temperature cannot fluctuate too much while the indoor air quality is improved, and the comfort of a user is improved.
