Removing under formaldehyde operational mode, formaldehyde sensor still detects real-time sampling concentration of formaldehyde value (Cs in real time
hCHO).According to embodiments of the invention, set the sampling return difference value (X) that enters/exit except formaldehyde operational mode.This sampling return difference value (X) is the concentration of formaldehyde setting value (G that exceeds standard
hCHO) margin value, its effect is basic identical with the effect of first scheduled time, is all for fear of cause motor damage in critical point frequent transitions operational mode.If it is satisfied that formaldehyde examination control module 1 is judged following condition:
Condition 3, (real-time sampling concentration of formaldehyde value (Cs
hCHO)-concentration of formaldehyde sampling a reference value (C
hCHO)) < (concentration of formaldehyde setting value (G that exceeds standard
hCHO)-enter/exit is except the sampling return difference value (X) of formaldehyde operational mode),
1 output of formaldehyde examination control module is exited except formaldehyde status signal, and program enters S4.
S4, in response to exiting except formaldehyde status signal, or turn-offs except formaldehyde switch, and air-conditioner control module control air-conditioner exits except formaldehyde operational mode.
That in response to formaldehyde examination control module 1, sends exits except formaldehyde status signal, and air-conditioner control module control air-conditioner exits except formaldehyde operational mode.If now air-conditioner is in holding state, in air-conditioner control module control room, air supply motor stops; Formaldehyde examination control module 1 is controlled except the bracing frame of formaldehyde module 2 and is packed up, and receiving member is exited from the wind inlet channel of air-conditioner.If now air-conditioner is in running status, in air-conditioner control module control room, air supply motor keeps original state; Formaldehyde examination control module 1 is controlled except the bracing frame of formaldehyde module 2 and is packed up, and receiving member is exited from the wind inlet channel of air-conditioner.
