In actual operation, the rotating speed of the fresh air fan is increased along with the increment of the carbon dioxide concentration, so that the air refreshing efficiency is improved.
In this embodiment, under the concentration of indoor different carbon dioxide, new trend fan has corresponding rotational speed to, when carbon dioxide concentration is higher, the rotational speed of new trend fan increases along with the increment of carbon dioxide concentration, like this, under different circumstances, guarantees the efficiency of renewing of indoor air, can not cause harm to the user because of indoor air quality is poor, and furthest's improvement user's experience of blowing. Compared with the fresh air function of the air conditioner in the prior art, the fresh air control method provided by the invention ensures the safety of users and improves the user experience.
Referring to fig. 1 in combination, in an embodiment of the invention, when the carbon dioxide concentration is higher than the set value, the step of determining the rotation speed increment according to the value of the carbon dioxide concentration higher than the set value includes:
determining a concentration interval in which carbon dioxide is located when the carbon dioxide concentration is higher than the set value, wherein the concentration interval comprises a first interval, a second interval, a third interval, a fourth interval and a fifth interval which are sequentially increased from the set value; the corresponding interval range is set so as to determine the rotation speed increment of the corresponding fresh air fan and reduce the technical threshold. In this embodiment, the first interval is 400PPM-700PPM, the second interval is 700PPM-1000PPM, the third interval is 1000PPM-2500PPM, the fourth interval is 2500PPM-5000PPM, and the fifth interval is higher than 5000 PPM.

and determining the initial rotating speed according to the number of people in the room.
The initial rotating speed of the fresh air fan is related to the number of people, and the more the exhaled carbon dioxide is, the more easily the indoor air quality becomes, so that the initial rotating speed is increased along with the increase of the number of people, thereby ensuring the indoor high-efficiency air exchange.
Specifically, as described above, in this embodiment, the range of the initial rotational speed is 200-400r/min, so that in one embodiment, when the number of people in the room is one, the initial rotational speed is 200r/min, and as the number of people increases by one, the initial rotational speed increases by 20r/min, and does not exceed 400r/min at the highest.
Referring to fig. 2 in combination, in addition, in an embodiment of the present invention, the fresh air control method further includes:
201, acquiring fresh air absolute humidity, air conditioner air absolute humidity and indoor absolute humidity under the condition that the carbon dioxide concentration is not higher than a set value; as described above, when the carbon dioxide concentration is low, the actual rotation speed of the fresh air fan is the initial rotation speed, and at this time, the carbon dioxide concentration is not increased in the continuous operation process of the fresh air fan, so that the fresh air fan keeps running at a continuous constant rotation speed. When the fresh air absolute humidity is the absolute humidity of the fresh air entering the room when the fresh air function is started, the fresh air absolute humidity can be determined according to the actual wind speed, the outdoor temperature, the condensation point temperature and the water vapor pressure of the fresh air fan; the absolute humidity of the air-conditioning wind is the absolute humidity of the air flowing into the room by the air-conditioning, and can be determined according to the rotating speed, the set temperature, the condensation point temperature and the water vapor pressure of the air-conditioning wind blower; the absolute indoor humidity may then be determined based on the current room temperature and the relative humidity.
202, determining the set time required by the indoor space to reach the target humidity according to the fresh air absolute humidity, the air-conditioning air absolute humidity, the indoor absolute humidity and the target humidity; here, the target humidity is 52% of the saturation humidity at the target temperature.
203, controlling the air conditioner to operate the fresh air function and the air conditioning function according to the set time.
Under the continuous operation condition of the air conditioning wind function and the fresh air function, the indoor humidity can reach the target humidity after the set time, and the humidity is the gold humidity at the target temperature, so that the user experience is improved. Compared with the prior art that corresponding humidification or dehumidification is carried out according to the mode that the sensor detects the indoor humidity, the invention does not need to additionally arrange the sensor, and ensures that the indoor is in the optimal humidity condition through operation, thereby ensuring indoor comfort, ensuring that the obtained indoor humidity is more accurate, and improving user experience.
In the above method, the temperature adjustment is performed according to the user's setting before the humidity adjustment, and the target humidity may be 52% of the saturation humidity at the set target temperature. In this way, after the step of controlling the air conditioner to operate the fresh air function and the air conditioning function according to the set time, the following steps are performed:
204, adjusting the actual wind speed of the fresh air fan to enable the absolute humidity of the fresh air to be the same as the absolute humidity of the air-conditioning air.
Therefore, the fresh air function and the air conditioning function have the same humidification and dehumidification effects, the indoor absolute humidity is always kept at the target humidity, namely 52% of the saturated humidity at the target temperature, and the continuous use experience of a user is improved.
Referring to fig. 2 in combination, in an embodiment of the invention, the step of determining the set time required for reaching the target humidity in the room according to the fresh air absolute humidity, the conditioned air absolute humidity, the indoor absolute humidity and the target humidity includes:
according to ρ Target object ＝ρ Fresh air ·t+ρ Environment (environment) -ρ Air conditioner ·t
The set time t is obtained, wherein ρ Target object For the target humidity ρ Fresh air For the absolute humidity of the fresh air, ρ Environment (environment) For the absolute indoor humidity ρ Air conditioner Absolute humidity is the air-conditioning wind.
The embodiment is a temperature and humidity adjustment method under the refrigeration condition, at this time, the fresh air increases the humidity, the air conditioner wind decreases the humidity, and it is known that when the absolute humidity of the environment is lower than the target humidity, the actual rotation speed of the fresh air fan can be correspondingly adjusted under the condition of keeping the air conditioner wind unchanged, so that the absolute humidity of the fresh air is higher than the absolute humidity of the air conditioner wind, the target humidity can be reached after the set time, and when the absolute humidity of the environment is higher than the target humidity, the absolute humidity of the fresh air is lower than the absolute humidity of the air conditioner wind, and of course, the current actual rotation speed of the fresh air fan can reach the target humidity without adjustment.
In order to realize the above temperature and humidity adjustment method during heating, the temperature and humidity adjustment method is represented by formula ρ Target object ＝ρ Air conditioner ·t+ρ Environment (environment) -ρ Fresh air The set time t is determined by t, at this time, the humidity of the fresh air is reduced, the humidity of the air conditioner is increased, and under the condition of different absolute humidity of the environment, the actual wind speed of the fresh air fan can be adjusted by referring to the above, so that the target humidity is achieved, the user experience is improved, and of course, the target humidity can be achieved if the current actual rotation speed of the fresh air fan is not adjusted.
Of course, in other embodiments, the air speed of the air conditioner wind can be adjusted to realize the temperature and humidity adjustment under the condition of different absolute humidity environments according to the needs, and details are not repeated.
