In view of the above problems, an embodiment of the present application provides a fresh air control method, which can adjust the introduction speed of fresh air in time 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 an indoor environment, so that the air conditioner can maintain low-power and low-noise operation and meet the requirement of a user on indoor comfort.
The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In a first embodiment, please refer to fig. 1, fig. 1 is a flowchart illustrating a fresh air control method in a sleep mode according to an embodiment of the present application.
When a general user starts an air conditioner, in order to ensure the indoor refrigeration or heating effect, the user can select to tightly close a door and a window, meanwhile, the indoor air exchange with the outdoor air exchange is greatly weakened, so that the oxygen content in the indoor air is reduced and the carbon dioxide content is increased, when the user simultaneously starts a sleep mode and a fresh air mode, the indoor air quality can be improved by introducing the 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 is blindly adjusted to control the room temperature, the problems of noise and the like can be caused, in order to take account of 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 can be obtained in real time through a carbon dioxide sensor, wherein the measuring range of the carbon dioxide sensor is 10000ppm, and the measuring precision is read within +/-50 ppm + 3%, and determining the environment of the user according to the acquired indoor temperature, the outdoor temperature and the indoor carbon dioxide concentration, and adjusting the introduction speed of the fresh air according to the environment of the user.
Step S1, when the current indoor carbon dioxide concentration is higher than a concentration threshold value, operating a fresh air mode at a first air speed, wherein the concentration threshold value is a preset value, and specifically, the range of the concentration threshold value is 1000ppm-5000 ppm; because the carbon dioxide concentration in the air is about 400ppm in the natural state, the research shows that the cognitive ability is obviously reduced when people are in the carbon dioxide concentration of 1000ppm for more than 2.5 hours; when people are in the carbon dioxide concentration of 5000ppm, phenomena such as headache, somnolence or dullness can occur; when people are in the carbon dioxide concentration of 10000ppm, mild poisoning reaction can occur, so the comfort level of a user can be reduced when the carbon dioxide concentration is higher than 1000ppm, the concentration of the carbon dioxide is best not more than 5000ppm, and it needs to be explained that the threshold value of the carbon dioxide can be set by self according to the actual condition, for example, when the temperature difference between the inside and the outside is small, the value of the threshold value of the carbon dioxide can be small, and when the temperature difference between the inside and the outside is large, the value of the threshold value of the carbon dioxide can be large.
Step S2, when fresh air is introduced at a first wind speed, the fresh air will cause a certain fluctuation to the indoor temperature, in order to take account of indoor temperature control when introducing fresh air, firstly, it can be judged whether the current inside and outside temperature difference is smaller than a temperature difference threshold value, the inside and outside 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, concretely, the temperature difference threshold value can be set to 4 degrees, if the current inside and outside 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 will not cause a large fluctuation to the indoor temperature, at this moment, the current running state of the air conditioner is maintained, the fresh air mode is continuously run at the first wind speed, preferably, the speed of introducing fresh air and the indoor carbon dioxide concentration are set to be in positive correlation, when the carbon dioxide concentration is increased, the speed of introducing fresh air is accelerated, otherwise, when the carbon dioxide concentration is reduced, the speed of introducing fresh air is reduced, so that the comfort level of the air quality is dynamically maintained; if the current internal and external temperature difference is greater than or equal to the temperature threshold value, the difference between the indoor temperature and the outdoor temperature is large, and the introduced fresh air can cause large fluctuation to the indoor temperature.
Step S3, when the difference between the indoor temperature and the outdoor temperature is large, if the current indoor temperature is less than or equal to the outdoor temperature, the air conditioner is in a cooling mode generally corresponding to hot summer nights, compared with the temperature reduction, the sensitivity of the user to the temperature rise is not so high, at this time, the current operation state of the air conditioner is maintained, namely, the fresh air mode is operated at the first wind speed; if the current indoor temperature is higher than the outdoor temperature, generally corresponding to cold winter nights, the sensitivity of the user to temperature reduction is higher than the sensitivity to temperature rise, the indoor temperature can be greatly reduced due to the introduced fresh air, the user can feel cool easily or the heating effect of the air conditioner is poor, so that the user experience is influenced, and at the moment, the step S4 is executed.
And step S4, stopping running the fresh air mode or running the fresh air mode at a second wind speed, wherein the second wind speed is less than the first wind speed.
In the embodiment of the application, after a user starts the sleep mode of the air conditioner, the air conditioner can monitor the current indoor temperature and the indoor carbon dioxide concentration in real time; if the concentration of the current indoor carbon dioxide is higher than the concentration threshold value, the fresh air mode is operated at a first wind speed to introduce outdoor fresh air, because the introduced fresh air can bring certain fluctuation to the indoor temperature, if the indoor temperature is controlled by the air conditioner host machine in a blind manner, the problems of noise and the like can be caused, the requirements of a user on noise and comfort level during sleeping are higher, in order to take the air quality and the indoor temperature into consideration, whether the current internal and external temperature difference is smaller than the temperature difference threshold value or not 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 large, 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 higher than the outdoor temperature or not is judged, if so, the outdoor is cold, the introduced fresh air can greatly reduce the indoor temperature, and at the fresh air mode is stopped or the fresh air mode is operated at the reduced wind speed, if not, the situation that the outdoor is hotter is shown, but because the sensitivity of the user to temperature drop is higher than the sensitivity to temperature rise, the fresh air is still introduced at the first wind speed until the indoor temperature is higher than the critical value of the temperature rise, the fresh air control method provided by the application can adjust the introduction speed of the fresh air in time according to the specific conditions of the indoor temperature, the outdoor temperature and the indoor carbon dioxide concentration, the influence of the fresh air introduced by the air conditioner in a sleep mode on the indoor environment is improved, the air conditioner can maintain low-power and low-noise operation, meanwhile, the indoor air quality is considered, and the requirement of the user on the indoor comfort level is met.
Example two
At hot summer night, when the inside and outside difference in temperature of indoor temperature and outdoor temperature is great, can rise indoor temperature by a wide margin because of the new trend of introducing, when indoor temperature was too high, probably let the user feel hot can be awaken by heat even to influence the comfort, in order when improving the indoor air quality, compromise the indoor temperature and can not fluctuate too greatly, this application has proposed corresponding scheme.
Referring to fig. 2, fig. 2 is a flow chart illustrating a fresh air control method in a cooling mode and a sleep mode according to an embodiment of the present application.
Step S101, on the basis of 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, because the air conditioner is in the cooling mode and the indoor temperature is much lower than the outdoor temperature, the introduced fresh air greatly increases the indoor temperature, but the sensitivity of the user to temperature increase is not so high compared with temperature decrease, and at this time, the current operation state of the air conditioner is continuously maintained, that is, the fresh air mode is operated at the first wind speed.
Step S102, with the introduction of fresh air, when the indoor temperature is too high, the user may feel hot or even be wakened up, so as to affect the comfort, and in order to prevent the indoor temperature from fluctuating too much, it is determined in real time whether the current indoor temperature is greater than a temperature rise threshold value, where the temperature rise threshold value includes: a user setting value and a first system setting value; preferentially selecting the smaller value of the user set value and the first system set value as a temperature rise critical value, if the current indoor temperature is less than or equal to the temperature rise critical value, maintaining the current operation state of the air conditioner, and continuing to operate the fresh air mode at the first air 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 a second wind speed.
And S103, when the fresh air mode stops running or runs at a second wind speed, gradually increasing the indoor carbon dioxide concentration, judging whether the current indoor carbon dioxide concentration is higher than a concentration threshold value in real time, if so, running the fresh air mode at a first wind speed, and if not, maintaining the current running state of the air conditioner, namely, stopping running the fresh air mode or running the fresh air mode at the second wind speed.
It should be noted that the second wind speed is less than the first wind speed, and the user set value is a temperature value set by a user.
