And S102, determining a first target rotating speed of the first fan, a second target rotating speed of the second fan and the on-off state of the throttling device according to the first air outlet temperature and the second air outlet temperature.
It is understood that the first target rotation speed of the first fan and the second target rotation speed of the second fan are determined according to the first outlet air temperature and the second outlet air temperature to respectively determine the target air output amounts of the first fan and the second fan, and the target amounts of the refrigerants flowing through the first indoor heat exchanger and the second indoor heat exchanger are determined according to the on-off state of the throttling device.

And S103, respectively adjusting the rotating speeds of the first fan and the second fan and controlling the opening or closing of the throttling device according to the first target rotating speed, the second target rotating speed and the opening or closing state of the throttling device.
That is, the rotating speeds of the first fan and the second fan are adjusted according to the first target rotating speed and the second target rotating speed, so that the rotating speed of the first fan reaches the first target rotating speed and the rotating speed of the second fan reaches the second target rotating speed, the first fan and the second fan respectively reach the target air output, and the throttling device is controlled to be opened or closed according to the on-off state of the throttling device, so that the target amount of refrigerant flowing through the first indoor heat exchanger and the second indoor heat exchanger is reached.
Specifically, in an embodiment of the present invention, the first indoor heat exchanger may be a single-layer heat exchanger, and the second indoor heat exchanger may be a multi-layer heat exchanger; alternatively, the first indoor heat exchanger may be a multi-layer heat exchanger, and the second indoor heat exchanger may be a single-layer heat exchanger.
It should be understood that, under normal conditions, when the first indoor heat exchanger is a single-layer heat exchanger and the second indoor heat exchanger is a multilayer heat exchanger, the heat exchange capacity of the first indoor heat exchanger is lower than that of the second indoor heat exchanger, and when the first indoor heat exchanger is a multilayer heat exchanger and the second indoor heat exchanger is a single-layer heat exchanger, the heat exchange capacity of the first indoor heat exchanger is higher than that of the second indoor heat exchanger, and further, the opening or closing of the throttling device is controlled, so that the first fan and the second fan output first outlet air temperature and second outlet air temperature of different temperatures, and different temperature requirements at the same time are met.
Specifically, in an embodiment of the present invention, the first indoor heat exchanger may be a heat exchanger with a first pipe diameter, and the second indoor heat exchanger may be a heat exchanger with a second pipe diameter, where the first pipe diameter is higher than the second pipe diameter, or the first pipe diameter is lower than the second pipe diameter.
It should be understood that, under normal conditions, when the first pipe diameter is higher than the second pipe diameter, the heat exchange capacity of the first indoor heat exchanger is higher than that of the second indoor heat exchanger, and when the first pipe diameter is lower than the second pipe diameter, the heat exchange capacity of the first indoor heat exchanger is lower than that of the second indoor heat exchanger, and further, the opening or closing of the throttling device is controlled, so that the first fan and the second fan output the first outlet air temperature and the second outlet air temperature at different temperatures, and different temperature requirements at the same time are met.
The following further describes the control method of the air conditioner according to an embodiment of the present invention with reference to an implementation flow of an embodiment of the present invention.
Specifically, when the air conditioner operates in a refrigerating mode (1), if the throttling device is closed, a refrigerant firstly enters the first indoor heat exchanger and then enters the second indoor heat exchanger connected in series with the first indoor heat exchanger for heat exchange, at the moment, a refrigerant in the second indoor heat exchanger is in an overheated state, the second air outlet temperature corresponding to the second fan is obviously higher than the first air outlet temperature of the first fan corresponding to the first indoor heat exchanger, further, the air outlet quantities of the first fan and the second fan are adjusted by adjusting the target rotating speeds of the first fan and the second fan, different first air outlet temperature and second air outlet temperature are output, and at the moment, the first air outlet temperature is lower than the second air outlet temperature; (2) if throttling arrangement opens, then during the refrigerant directly enters into second indoor heat exchanger, and first indoor heat exchanger no longer carries out the heat transfer or the heat transfer volume is very little, therefore first air-out temperature that first fan corresponds is the same with indoor ambient temperature basically, and the second air-out temperature that the second fan corresponds will be very low, and then, through the target rotational speed of adjusting first fan and second fan, adjust the air output of first fan and second fan to output different first air-out temperature and second air-out temperature, at this moment, first air-out temperature is higher than second air-out temperature.
It should be noted that, when the air conditioner is in heating operation, the refrigerant is in an opposite state to the cooling operation state (1), if the throttling device is closed, the first indoor heat exchanger and the second indoor heat exchanger are connected in series, and the second air outlet temperature of the second fan corresponding to the second indoor heat exchanger is lower than the first air outlet temperature of the first fan corresponding to the first indoor heat exchanger, at this time, the hot air corresponding to the first indoor heat exchanger can be blown downwards by matching with the air outlet or the air guide mechanism, so as to achieve the purpose of foot warming, and meanwhile, the slightly lower air temperature corresponding to the second indoor heat exchanger is blown upwards, so as to disturb the hot air in the upper room to go downwards, so as to achieve the purpose of energy saving; (2) if the throttling device is opened, the refrigerant directly flows through the second indoor heat exchanger instead of the first indoor heat exchanger, so that the pressure difference (particularly under the low-temperature working condition) of the air conditioning system is quickly established, and the purposes of quickly heating and quickly discharging hot air are achieved.
In summary, according to the control method of the air conditioner in the embodiment of the present invention, an outlet air temperature adjustment instruction is received, where the outlet air temperature adjustment instruction includes a first outlet air temperature corresponding to a first fan and a second outlet air temperature corresponding to a second fan, and a first target rotation speed of the first fan, a second target rotation speed of the second fan, and an on-off state of a throttling device are determined according to the first outlet air temperature and the second outlet air temperature, so as to respectively adjust rotation speeds of the first fan and the second fan and control the throttling device to be opened or closed according to the first target rotation speed, the second target rotation speed, and the on-off state of the throttling device.
