Preferably, the occupation ratio of the fresh air in the air conditioning air is defined as the fusion amount G of the fresh air, the larger the fusion amount G is, the more the fresh air is sent to the fresh air demand area, the smaller the fusion amount G is, the less the fresh air is sent to the fresh air demand area, and the fusion amount G is in the threshold range by adjusting the rotating speed of the fresh air fan.
Specifically, the fusion amount G satisfies the following relationship:
wherein r is1For the new fan 21 speed, r2The rotating speed of the air conditioner fan is set, namely the fixed rotating speed corresponding to the running gear of the air conditioner, A1And A2Is constant, wherein A1/A2The value range of (A) is 0.7-1.
Preferably, the setting range of the fusion amount G is (70% -90%, including 70% and 90%), if the fusion amount is less than 70%, the requirement of a human body on fresh air cannot be met due to small fusion amount, if the fusion amount is more than 90%, a user wants the fusion amount to be higher and better in practical use, but if the fresh air enters the room from the outside, the indoor temperature is fluctuated due to too much fresh air, the user body feeling is influenced, the output of the refrigerating and heating capacity of an air conditioner is influenced, or the output power is large, so that energy is not saved.
When the fusion amount G is less than or equal to the first threshold value, the rotating speed of the fresh air fan 21 is controlled to be increased,

If G is more than 90 percent in the next adjustment, namely the second threshold value is 90 percent, the fresh air rotating speed r1Detecting the fusion amount G after reducing by 10r each time, and outputting the final fresh air rotating speed r until the G is less than or equal to 90 percent1. In the control logic, G is selected to be in an optimal range of 70% -90%, the closer G is to 90%, the better the G is, if the G is calculated to be more than or equal to 70% for the nth time, the next regulation is carried out, meanwhile, the feedback regulation is carried out for the (n + 1) th time, the fusion amount G is calculated after the rotation speed of the fresh air is increased by 10r, if the fusion amount G is more than the nth time (the closer G is to 90%), the fusion amount G for the nth time is covered, the fusion amount G for the (n + 1) th time is selected, the closer 90% is the better, and the optimal rotation speed r is finally output1。
As shown in fig. 3, in another embodiment, the indoor unit of the dual-outlet fresh air conditioner further includes a carbon dioxide detecting device, which controls the rotation speed of the fresh air blower 21 according to the detected carbon dioxide concentration value, when the carbon dioxide concentration value is higher than a first concentration threshold, the rotation speed of the fresh air blower 21 is increased, and when the carbon dioxide concentration value is lower than a second concentration threshold, the rotation speed of the fresh air blower 21 is decreased, where the first concentration threshold is greater than the second concentration threshold.
When a user uses the air conditioner, the air conditioner is started, the initial rotating speed of the fresh air fan 21 and the initial rotating speed of the air conditioner fan are set according to the user when the user uses the air conditioner, and the air conditioner body detects indoor CO in real time2Concentration of CO in the room if detected2The concentration is higher than the concentration threshold value (this set value is written in the program), the rotation speed r of the new fan 21 is1Return to detecting indoor CO every 10r increase2Concentration, and circulating in this way until indoor CO is detected2If the concentration is lower than the concentration threshold, the fresh air concentration threshold rotating speed r1Then 10r is reduced on the original basis to obtain the current calculated rotating speed r1。
Preferably according to CO2After the rotating speed of the fresh air machine 21 is determined according to the concentration, the rotating speed of the fresh air machine 21 is adjusted according to the fusion amount G, and the method specifically comprises the following steps:
the system calculates the current rotating speed r1Substituting the formula of the fusion amount G into the formula of the fusion amount G to obtain a value of the fusion amount G, and if G is calculated to be less than 70%, determining the rotating speed r of the fresh air fan 211Detection after every 10r increaseThe fusion amount G is added until the G is more than or equal to 70 percent, the next regulation is carried out, and if the G is more than 90 percent in the next regulation, the rotating speed r of the fresh air fan 21 is1Detecting the fusion amount G after reducing by 10r each time, and outputting the final rotating speed r of the fresh air fan 21 until the G is less than or equal to 90 percent1. In the control logic, G is selected to be in an optimal range of 70% -90%, the closer G is to 90%, the better the G is, if the G is calculated to be more than or equal to 70% for the nth time, the next regulation is carried out, meanwhile, the feedback regulation is carried out for the (n + 1) th time, the fusion amount G is calculated after the rotation speed of the fresh air is increased by 10r, if the fusion amount G is more than the nth time (the closer G is to 90%), the fusion amount G for the nth time is covered, the fusion amount G for the (n + 1) th time is selected, the closer 90% is the better, and the optimal rotation speed r is finally output1。
