In other embodiments, when T1D > X > T4D and T2D > X > T3D are simultaneously performed, the indoor fan is determined to be the first fan type, and the outdoor fan is determined to be the second fan type; and when T1D < Y < T4D and T2D < Y < T3D simultaneously, determining that the outdoor fan is the first fan type and determining that the indoor fan is the second fan type.
The first set threshold and the second set threshold are preset fixed parameters.
In this embodiment, the indoor and outdoor temperature variation parameters satisfy a certain size relationship, and the numerical value of the large temperature variation value is required to be ensured to be large enough, so as to ensure that the currently opened fan is the indoor fan and the currently closed fan is the outdoor fan when the current indoor side temperature variation is obvious enough, and ensure that the currently opened fan is the outdoor fan and the currently closed fan is the indoor fan when the current outdoor side temperature variation is obvious, so as to ensure that the currently opened fan is the outdoor fan and the currently closed fan is the indoor fan, thereby realizing the accuracy of distinguishing the indoor fan from the outdoor fan.
Further, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 4, the step of controlling the first fan to be in an on state includes:
step S11, when the air conditioner is in a preset mode, controlling the first fan to operate according to a first indoor fan control parameter corresponding to the preset mode; the preset mode comprises a refrigeration mode or an air supply mode;
and step S12, when the air conditioner is in a heating mode, controlling the first fan to operate according to the control parameter of the first outdoor fan corresponding to the heating mode.
Based on this, because the compressor is closed under the air supply mode and can lead to outdoor side temperature change unobvious, the compressor is opened under the refrigeration mode and can make indoor side temperature change obviously, consequently control indoor outer temperature variation value that detects on the basis of indoor fan control parameter operation of the first fan that needs to open at present under these two modes, be favorable to guaranteeing to discern indoor fan and outdoor fan fast, accurate based on the indoor outer temperature variation condition that detects.
And the compressor is started in the heating mode to obviously change the temperature of the outdoor side, so that the indoor and outdoor temperature change values detected on the basis of controlling the first fan to be started to operate according to the outdoor fan control parameters in the heating mode are favorable for ensuring that the indoor fan and the outdoor fan can be quickly and accurately identified based on the detected indoor and outdoor temperature change conditions.
Further, the first temperature variation value includes the indoor environment temperature variation value and the indoor heat exchanger temperature variation value, and the second temperature variation value includes the outdoor environment temperature variation value and the outdoor heat exchanger temperature variation value and further includes:
in the preset mode, when the first temperature change value is larger than the second temperature change value, if the first temperature change value and the second temperature change value do not meet the first preset condition, controlling the first fan to operate according to the first indoor fan control parameter, and controlling the second fan to operate according to the second outdoor fan control parameter corresponding to the preset mode;
in the heating mode, when the first temperature variation value is greater than the second temperature variation value, if the first temperature variation value and the second temperature variation value do not satisfy the second preset condition, the first fan is controlled to operate according to the first outdoor fan control parameter, and the second fan is controlled to operate according to the second indoor fan control parameter corresponding to the heating mode.
The first temperature variation value and the second temperature variation value not meeting the first preset condition specifically means that the first temperature variation value is less than or equal to a first set threshold, or the first set threshold is less than or equal to the second temperature variation value.
The first temperature variation value and the second temperature variation value not meeting the second preset condition specifically means that the first temperature variation value is greater than or equal to a second set threshold, and the second set threshold is greater than or less than the second temperature variation value.
Specifically, the first temperature variation value includes the indoor environment temperature variation value and the indoor heat exchanger temperature variation value, and the second temperature variation value includes the outdoor environment temperature variation value and the outdoor heat exchanger temperature variation value, then:
in this embodiment, in the cooling or blowing mode, when the variation values corresponding to the indoor and outdoor ambient temperatures and the heat exchanger temperature do not satisfy T1D > X > T4D, or T2D > X > T3D, the first fan may be controlled to operate according to the first indoor fan control parameter, and the second fan may be controlled to operate according to the second outdoor fan control parameter corresponding to the preset mode. In the heating mode, when the variation values respectively corresponding to the indoor and outdoor ambient temperatures and the heat exchanger temperature do not satisfy T1D < Y < T4D, or T2D < Y < T3D, the first fan may be controlled to operate according to the first outdoor fan control parameter, and the second fan may be controlled to operate according to the second indoor fan control parameter corresponding to the heating mode.
In a refrigeration mode or an air supply mode, in the process of controlling the operation of a first fan which is started currently according to indoor fan control parameters, the detected indoor side temperature change value is larger than the outdoor side temperature change value, but when the indoor side temperature change amplitude is small, the indoor and outdoor fans can not be distinguished accurately, the indoor fan control parameters in the current mode are maintained to control the operation of the first fan, the outdoor fan control parameters in the current mode are used to control the operation of a second fan, and therefore the distinguishing accuracy of the indoor and outdoor fans is improved. Specifically, the step S10 may be executed in the process of maintaining the indoor fan control parameter in the current mode to control the first fan to operate, and controlling the second fan to operate according to the outdoor fan control parameter in the current mode, so as to identify the indoor and outdoor fans based on the indoor and outdoor temperature changes again.
In the heating mode, in the process of controlling the currently started first fan to operate according to the control parameters of the outdoor fan, the detected indoor side temperature change value is smaller than the outdoor side temperature change value, but when the outdoor side temperature change amplitude is smaller, the indoor and outdoor fans cannot be accurately identified, the control parameters of the outdoor fan in the heating mode are maintained to control the first fan to operate, the control parameters of the indoor fan in the heating mode are used to control the second fan to operate, and therefore the accuracy of distinguishing the indoor fan from the outdoor fan is further improved. Specifically, the step S10 may be executed in the process of maintaining the operation of the first fan under the outdoor fan control parameter in the heating mode, and controlling the operation of the second fan under the indoor fan control parameter in the heating mode, so as to identify the indoor and outdoor fans based on the indoor and outdoor temperature changes again.
