Specifically, as shown in fig. 1, the control method of the air conditioner includes the steps of: s1, refrigerating operation of the air conditioner; s2, starting a fresh air fan of the air conditioner; s3, acquiring indoor humidity, air quality and outdoor environment temperature; s4, judging whether the indoor humidity is larger than or equal to a first preset indoor humidity or not; s5, when the judgment result in the step S4 is yes, S51, if the air quality is excellent and the outdoor environment temperature is more than or equal to the preset outdoor environment temperature, controlling the fresh air fan to stop running; and S52, if the air quality is medium and the outdoor environment temperature is greater than or equal to the preset outdoor environment temperature, controlling the fresh air fan to run at low wind.
Wherein, the quality of air can be detected by detecting CO in the indoor air2The concentration of (2) is judged. When the air quality is excellent, CO2Concentration is less than 700ppm, when the air quality is medium, 700ppm is less than or equal to CO2Concentration less than 1000ppm, CO when air quality is inferior2The concentration is more than or equal to 1000 ppm.
If the air quality is excellent and the outdoor environment temperature is more than or equal to the preset outdoor environment temperature, the fresh air fan is controlled to stop running, the indoor environment temperature is high, the comfort level of a user is high, the fresh air fan is stopped, energy saving can be achieved, outdoor high-temperature air can be prevented from being introduced, the refrigeration effect is reduced, and the situation that the user feels uncomfortable is caused. Simultaneously, if indoor environment humidity is too high, because of the air conditioner has certain dehumidification effect under the refrigeration mode, and then can dehumidify the room air, close the new trend fan and can guarantee the dehumidification effect.
According to the control method of the air conditioner, when the air conditioner operates in a refrigerating mode, the main control system of the air conditioner can adjust the operation state of the fresh air fan according to the detected indoor humidity, air quality and outdoor environment temperature, introduce fresh air to adjust the indoor air quality, and meanwhile can control the indoor humidity so as to improve the comfort level of users. When the air quality is excellent and the outdoor environment temperature is more than or equal to the preset outdoor environment temperature, the fresh air fan is controlled to stop running so as to play a role in energy conservation and ensure the refrigeration effect. In the air quality, the fresh air fan runs at low wind, the indoor air quality is improved, meanwhile, the influence of outdoor environment temperature on the indoor temperature is reduced, and then the comfort level and the health of a user can be guaranteed to the greatest extent.
In some embodiments, with reference to fig. 1, in step S4, it is determined whether the indoor humidity is greater than or equal to a first preset indoor humidity and is less than a second preset indoor humidity, where the second preset indoor humidity is greater than the first preset indoor humidity. In the step S5, when the judgment result in the step S4 is yes, S53, if the air quality is excellent and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to operate intermittently according to the received wind speed instruction; and S54, if the air quality is medium and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to operate intermittently according to the received wind speed instruction.
When the indoor humidity is between the first preset indoor humidity and the second preset indoor humidity and the outdoor environment temperature is lower than the preset outdoor environment temperature, if the environment quality is excellent, the air conditioner controls the fresh air fan to operate intermittently, for example, the fresh air fan can be turned on for 1 hour and turned off for 0.5 hour to realize the energy-saving constant indoor temperature, the indoor humidity and the indoor air quality are kept within a comfortable temperature range, the comfort level of a user is increased, and from the energy-saving perspective, when the outdoor environment is low, the indoor humidity is appropriate and the indoor air quality is excellent, the energy-saving effect can be realized by the intermittent operation of the received wind speed instruction.
When indoor humidity is between the first preset indoor humidity and the second preset indoor humidity, and outdoor environment temperature is less than the preset outdoor environment temperature, if the environment quality is middle, the air conditioner controls the intermittent operation of the fresh air fan, the indoor air quality can be improved, the long-time continuous operation of the fresh air fan can be avoided, the indoor temperature is increased, the working frequency of the compressor of the air conditioner is increased, the indirect energy-saving effect is achieved, and the influence of the fresh air fan on the indoor temperature during working is reduced.
In some embodiments, as shown in fig. 1, step S5 further includes: s55, if the air quality is poor and the outdoor environment temperature is greater than or equal to the preset outdoor environment temperature, controlling the fresh air fan to run at low wind; and S56, if the air quality is poor and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to operate according to the received wind speed instruction.
When the indoor humidity is at the first preset indoor humidity and the second preset indoor humidity and the indoor environment quality is bad, if the outdoor environment temperature is more than or equal to the preset outdoor environment temperature, the air conditioner controls the low-wind operation of the fresh air fan, and when the fresh air is introduced to change the indoor air quality, the outdoor environment temperature higher than the indoor temperature due to the overlarge introduced air volume is avoided, and the influence of the outdoor environment temperature on the indoor temperature is reduced. If the outdoor environment temperature is lower than the preset outdoor environment temperature, when the fresh air is introduced to improve the indoor air quality, the fresh air fan can continuously operate according to the set air speed because the outdoor environment temperature is close to the indoor temperature, the speed of improving the indoor air quality is increased, and the experience feeling is better.
Specifically, the first preset indoor humidity is 45% and the second preset indoor humidity is 75% for illustration, but the first preset humidity and the second preset humidity are not limited, in the scheme, 45% -75% is taken as an example of a humidity comfort range of a human body, so that the air conditioner can control the operation of the fresh air fan as accurately as possible, the indoor humidity and the indoor air quality are improved, and the comfort of a user and the energy saving performance of the air conditioner are improved.
In some embodiments, as shown in fig. 2, in step S4, it is determined whether the indoor humidity is greater than or equal to a second preset indoor humidity, where the second preset indoor humidity is greater than the first preset indoor humidity. In the step S5, when the determination result in the step S4 is yes, S57, if the air quality is excellent and the outdoor environment temperature is less than the preset outdoor environment temperature, controlling the fresh air fan to operate in low wind; and S58, if the air quality is medium and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to operate according to the received wind speed instruction.
Therefore, when the indoor humidity is higher than the second preset indoor humidity and the outdoor environment temperature is lower than the preset outdoor environment temperature, if the indoor air quality is excellent, the air conditioner controls the fresh air fan to operate at a low speed to improve the air quality and reduce the influence of the outdoor environment temperature on the indoor temperature; if the indoor air quality is in the middle, the air conditioner controls the fresh air fan to operate according to the instruction of the user, the indoor air quality is improved, and the user experience is improved.
In some embodiments, as shown in fig. 2, step S5 further includes: s59, if the air quality is poor and the outdoor environment temperature is greater than or equal to the preset outdoor environment temperature, controlling the high-wind intermittent operation of the fresh air fan; and S510, if the air quality is poor and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to continuously run in high wind. The reason is that when the outdoor environment temperature is higher than the preset outdoor environment temperature and the air quality is poor, the indoor air quality needs to be rapidly improved, meanwhile, the influence of the outdoor environment temperature on the indoor temperature needs to be reduced, the power consumption of the air conditioner for adjusting the indoor temperature rise is reduced, the influence of the outdoor environment temperature on the indoor temperature is reduced when the fresh air fan operates intermittently, and the energy-saving operation of the air conditioner is realized.
In some embodiments, as shown in fig. 3, step S4 is followed by: s6, when the judgment result in the step S4 is negative, S61, if the air quality is excellent and the outdoor environment temperature is more than or equal to the preset outdoor environment temperature, controlling the low-wind intermittent operation of the fresh air fan; and S62, if the air quality is medium and the outdoor environment temperature is greater than or equal to the preset outdoor environment temperature, controlling the fresh air fan to run at low wind.
When indoor humidity is less than first preset indoor humidity, and outdoor ambient temperature more than or equal to preset outdoor ambient temperature, when the indoor air quality that the air conditioner detected is excellent, the low wind intermittent type operation of air conditioner control new trend fan, when improving the indoor air quality, reduce outdoor ambient temperature to the influence of indoor outer temperature, avoid the indoor temperature to rise, influence the refrigeration effect of air conditioner, cause the air conditioner in order to make the indoor temperature reach preset temperature, the compressor frequently works, increase the consumption of air conditioner operation. When the detected indoor air quality is medium, the air conditioner controls the low wind continuous operation of the fresh air fan, and the influence of the temperature of introduced fresh air on the indoor temperature is reduced.
In some embodiments, as shown in fig. 3, in step S6, if the air quality is good and the outdoor temperature is lower than the preset outdoor temperature, S63, controlling the fresh air fan to operate at low wind; and S64, if the air quality is medium and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the wind running of the fresh air fan.
It can be understood that, when indoor humidity is less than first preset indoor humidity, outdoor ambient temperature is less than when presetting outdoor ambient temperature, if indoor air quality is excellent this moment, the air conditioner can control the low wind of new trend fan and continue the operation, can reduce the amount of wind, when promoting indoor humidity, reduces outdoor ambient temperature and to the excessive influence of indoor temperature, realizes the energy-conserving effect of air conditioner. If the indoor air quality is middle, the air conditioner can control the fresh air fan to continuously run in the wind, and the wind in the fresh air fan can be continuously run due to the fact that the outdoor environment temperature is low and the influence on the indoor temperature is small, and indoor humidity and indoor air quality are rapidly improved.
In some embodiments, referring to fig. 3, step S6 further includes: s65, if the air quality is poor and the outdoor environment temperature is greater than or equal to the preset outdoor environment temperature, controlling the fresh air fan to run at low wind; and S66, if the air quality is poor and the outdoor environment temperature is lower than the preset outdoor environment temperature, controlling the fresh air fan to run in high wind.
From this, when outdoor ambient temperature more than or equal to predetermine outdoor ambient temperature, in order to reduce outdoor ambient temperature to indoor temperature's influence, the air conditioner control new trend fan low wind lasts the operation, avoids changing the new trend in-process and introduces too much new trend that has a high temperature to indoor temperature's influence, for example, indoor temperature's rise under the refrigeration mode reduces user's comfort level, and new trend fan low wind operation can reduce outdoor ambient temperature to indoor temperature's influence. When the outdoor environment temperature is lower than the preset outdoor environment temperature, the outdoor environment temperature is relatively suitable, the air conditioner can control the high-wind operation of the fresh air fan, the introduced indoor fresh air quantity is large, the rapid rise of the indoor air quality can be realized, and the comfort level of a user is improved.
In some embodiments, the preset outdoor ambient temperature is 36 ℃, but is not limited to 36 ℃. The preset outdoor environment temperature can be any temperature value within the temperature range of 30-38 ℃, the preset outdoor environment temperature is preferably 36 ℃, the preset outdoor environment temperature is set according to the human body temperature, the running state of the fresh air fan can be controlled reasonably, and the use experience of a user is improved.
