2) controller (5) is according to actual temperature value T and CO2The operational mode of actual concentrations value X selection fresh air conditioners is specific to select It is as follows to select process：
As T >=T1 and X >=X1, selection refrigeration plus fresh air pattern, and open the electrostatic dust removal filter case in fresh air pipeline (8) (13)；
As T >=T1 and X ＜ X1, separate refrigeration pattern is selected；
As T≤T2 and X >=X1, selection heating plus fresh air pattern, and open the electrostatic dust removal filter case in fresh air pipeline (8) (13)；
As T≤T2 and X ＜ X1, independent heating mode is selected；
As T2 ＜ T ＜ T1 and X >=X1, independent fresh air pattern is selected, and open the electrostatic dust removal filter case in fresh air pipeline (8) (13)；
As T2 ＜ T ＜ T1 and X ＜ X1, stop the operation of fresh air conditioner；
Wherein T1, T2 are preset normal temperature value, and T1 ＞ T2, X1 are preset CO2The standard density；
3) enter under the operational mode of selection and run, and return to step 1)；
24 DEG C≤T1≤28 DEG C, -5 DEG C≤T2≤15 DEG C, 350≤X1≤1000ppm.
