The indoor unit of the air conditioner reaches different temperatures through the inner pipe temperature of the evaporator, the rotating speed of the fresh air motor is controlled, and the fresh air quantity is regulated, so that fresh air after defrosting is finished enters the room and the use experience of a user is not influenced. The control method of the application automatically controls the air supply mode by judging the temperature of the inner tube of the evaporator.
When the air conditioner is in cold air prevention logic condition after the air conditioner finishes heating defrosting, the temperature T of the air conditioner inner tube is set to 35 ℃, and when the temperature T of the air conditioner inner tube is set to 1 And when the temperature is not less than 35 ℃, exiting the cold air prevention logic. In order to meet the fresh air requirement of a user during the cold air prevention period of an air conditioner and ensure the comfort problem, a fresh air function control logic is invented, as shown in figure 1.
As shown in fig. 2The air conditioner of the present application includes two centrifugal fans and four air outlets, and two air outlets are respectively provided at the upper and lower portions of the air conditioner, and each air outlet is provided with a baffle, specifically, the first upper wind shielding portion 41, the first lower wind shielding portion 42, the second upper wind shielding portion 51, and the second lower wind shielding portion 52 may be baffles. When the air conditioner operates in a heating mode and heats after entering a defrosting mode, under the condition that the indoor air environment is poor, the indoor air is required to be improved by the air conditioner, the indoor air is detected by an environment monitoring device of the air conditioner, and when the monitoring value reaches a set value, the fresh air function of the air conditioner is started. As shown in fig. 3, the fresh air motor sends outdoor fresh air to four air outlets (namely, a first upper air outlet 21, a first lower air outlet 22, a second upper air outlet 31 and a second lower air outlet 32) of the whole machine through the fresh air outlet. The air conditioner fresh air system actually detects the temperature T of the inner tube of the evaporator during the operation of the air conditioner 1 Compared with the temperature T of the inner pipe set by the air conditioner, the rotational speed and the air supply mode of the two centrifugal fan blades and the fresh air motor are controlled by the difference delta T of the two centrifugal fan blades and the fresh air motor.
When the air conditioner operates under the logic after the defrosting operation, the operation modes of all parts of the inner machine under different temperature differences are as follows: when the temperature T of the inner tube of the evaporator 1 When 20 ℃ is not reached, i.e. Δt=t 1 -T < -15 ℃, when the fresh air temperature is low, the cold air is prevented from blowing feet, as shown in fig. 3, the first lower wind shielding part 42 and the second lower wind shielding part 52 are closed, in addition, the first upper wind shielding part 41 and the second upper wind shielding part 51 are opened, and the fresh air enters the room through the two upper air outlets; on the premise of meeting the fresh air quantity, the rotating speed of the fresh air motor is smaller, and the rotating speed of the fresh air motor is a low wind gear under the condition; the centrifugal fan blade for supplying air is operated by a lower fan with the rotating speed smaller than that of an upper fan, and the upper fan is closed.
Along with the increase of the tube temperature of the evaporator, the temperature is 20 ℃ to less than or equal to T 1 When the temperature is less than 35 ℃, namely delta T is less than or equal to minus 15 ℃ and less than 0 ℃, the rotating speed of the fresh air motor is increased, at the moment, the rotating speed of the fresh air motor is in a middle wind gear, the upper fan of the centrifugal fan blade is turned on, the lower fan is turned off, the first lower wind shielding part 42 and the second lower wind shielding part 52 are also turned off, in addition, the first upper wind shielding part 41 and the second upper wind shielding part 51 are turned on, and the air supply mode is upper air outlet.
When the temperature of the evaporator tube reaches 35 ℃ or higher, Δt=t 1 And the T is more than or equal to 0 ℃, the system exits the cold air prevention logic, the air outlet temperature is higher at the moment, the rotating speed of the fresh air motor reaches the maximum high air level, the upper centrifugal fan blade and the lower centrifugal fan blade are both opened, the maximum air quantity is ensured, the four baffles are all opened, and fresh air enters the room through the four air outlets, so that the aim of improving the indoor environment is fulfilled.
In the present embodiment, the evaporator inner tube temperature T can be set to be changed according to the user's demand. The fresh air function logic can be automatically started through the air conditioner environment monitoring device, and can be manually started or closed when a user needs fresh air.
Specifically, the first upper wind shielding portion 41 in the present embodiment corresponds to the mechanism 1 in fig. 1, the second upper wind shielding portion 51 corresponds to the mechanism 3 in fig. 1, the first lower wind shielding portion 42 corresponds to the mechanism 2 in fig. 1, and the second lower wind shielding portion 52 corresponds to the mechanism 4 in fig. 1. The first centrifugal fan 11 in this embodiment corresponds to an upper fan in the drawing, the second centrifugal fan 12 corresponds to a lower fan in the drawing 1, and both the upper fan and the lower fan are of centrifugal fan blade structures.
