receiving an external circulation adjusting instruction, and controlling the opening and closing structure 30 on the indoor air inlet 12 to completely close the indoor air inlet 12 to enable the indoor air inlet 12 to be in an R1 position by default, and controlling the opening and closing structure 30 on the fresh air inlet 13 to adjust the fresh air inlet 13 to be in a K5 position by default; the opening and closing structure 30 on the fresh air inlet 13 is manually controlled to adjust the fresh air inlet 13 to be at any position of K1-K5.
Preferably, the method comprises the steps of,
and receiving an internal and external circulation adjusting instruction, wherein the opening and closing structure 30 on the fresh air inlet 13 adjusts the fresh air inlet 13 to be positioned at a K3 position, and the opening and closing structure 30 on the indoor air inlet 12 adjusts the indoor air inlet 12 to be positioned at an R3 position.
Further, the method comprises the steps of,
receiving an automatic adjustment instruction, comprising:
detecting an indoor temperature T1, detecting the position Ka where the opening and closing structure 30 on the fresh air inlet 13 currently adjusts the opening of the fresh air inlet 13, and detecting the position Rb where the opening and closing structure 30 on the indoor air inlet 12 currently adjusts the opening of the indoor air inlet 12;
when the indoor temperature T1 is less than or equal to the preset temperature T;
if a=1, 2,3,4, the opening and closing structure 30 on the fresh air inlet 13 adjusts the opening of the fresh air inlet 13 to be at the K (a+1) position, and then maintains the state to run for 30min;
if a=5, b=2, 3,4,5, the opening and closing structure 30 on the indoor air inlet 12 adjusts the opening of the indoor air inlet 12 to be at the R (b-1) position, and then maintains the state to run for 30min;
when a=5, a=1, the state is maintained for 30min;
when the indoor temperature T1 is more than the preset temperature T;
if b=1, 2,3,4, the opening and closing structure 30 on the indoor air inlet 12 adjusts the opening of the indoor air inlet 12 to be at the R (b+1) position, and then maintains the state to run for 30min;
if b=5, a=2, 3,4,5, the opening and closing structure 30 on the fresh air inlet 13 adjusts the opening of the indoor air inlet 12 to be at the K (a-1) position, and then maintains the state to run for 30min;
when b=5, a=1, this state is maintained for 30min.
Here, the preset temperature t=the set temperature t0+t2 (T2 is a set value when the program leaves the factory, and is determined by the configuration of the whole machine, the thermal efficiency of the two machines, the rotation speed of the motor, the size of the housing, the air duct structure, and the like).
Receiving an automatic regulation instruction, and when the indoor temperature T1 is detected to be less than or equal to the preset temperature T, gradually opening the air inlet of the fresh air inlet 13 and gradually closing the air inlet of the indoor air inlet 12; when the indoor temperature T1 is detected to be more than the preset temperature T, the fresh air inlet 13 is gradually closed for air intake, and the indoor air inlet 12 is gradually opened for air intake. The purpose of automatic regulation and control is to increase the fresh air inlet 13 as much as possible under the premise of ensuring the indoor temperature of a user and the use comfort, increase the fresh air inlet quantity and maximize fresh air exchange.
Specifically, if the indoor temperature meets the condition (i.e. is lower than the preset temperature T) and the current indoor temperature reaches the user-set demand temperature, then under the premise, the fresh air inflow needs to be increased as much as possible, the indoor air inflow needs to be reduced (the priority of increasing the fresh air inflow is higher than that of reducing the indoor air inflow), so if the fresh air intake wind shield is not opened to the maximum, the fresh air wind shield opening is increased (1 is less than or equal to a < 5), if the fresh air intake wind shield opening is opened to the maximum, the fresh air intake wind shield opening is gradually reduced until all the fresh air intake wind shield opening is closed (a=5), but the room temperature needs to be ensured to reach the user-set demand temperature in the adjustment process, and therefore, a period of time T is required to be operated after each adjustment, in the embodiment, the time T is 30 minutes, and the relationship between the indoor temperature and the user-set temperature is detected again after the fresh air intake wind shield opening is stabilized.
Otherwise, if the indoor temperature does not meet the condition (i.e. is higher than the preset temperature T), the fresh air inflow needs to be reduced, the indoor air inflow needs to be increased (in order to ensure that more fresh air is available as possible, the priority of increasing the indoor air inflow is higher than that of reducing the fresh air inflow), and the rest steps are the same.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
