Thus, the air conditioner control method of the present invention can determine whether the cold airflow needs to be guided from the indoor side portion 20 to the radiator 40 and the flow rate of the cold airflow according to the real-time exhaust temperature T0 of the outdoor side portion 10, the temperatures of the components of the inverter controller 30, etc. to achieve the self-adaptive effect, and effectively solve the problem of temperature rise of the components of the inverter controller 30 when the outdoor side is at a high temperature.

The blades of the outdoor fan 11 of the outdoor part 10 and the blades of the indoor fan 22 of the indoor part 20 of the integral air conditioner in the prior art are respectively assembled on the two end shafts of the motor, and when the motor runs, the blades of the outdoor fan 11 and the blades of the indoor fan 22 rotate simultaneously.

The fan blades are centrifugal fan blades, under the suction force of the centrifugal fan blades, airflow on the indoor side enters the indoor side portion 20 from the inner side air inlet 25 (such as a grating or a through hole on a panel of an air conditioner) and the indoor heat exchanger 24, passes through the indoor heat exchanger 24 and then enters the indoor air inlet chamber, and then reaches the centrifugal fan blades through the air inlet on the volute casing 23, and the centrifugal fan blades push the air to the inner side air outlet 26 to supply air to the indoor side, so that a path for inside air circulation is formed.

In order to ensure the performance of the air conditioner during the refrigeration, the air entering the machine from the grilles or through holes on the panel must be completely discharged through the inner air outlet 26, so the outdoor part 10 and the indoor part 20 are isolated from each other except the air communication part which is arranged on the basis of the existing structure of the air conditioner and is shown in fig. 1 and 2, so that the air flow pushed by the centrifugal fan blade is completely discharged through the inner air outlet 26 without other paths.

The working process of the air conditioner of the invention is as follows:

(1) when the radiator 40 does not need cooling, the damper 70 is in a state of closing the gas circulation part, the outdoor part 10 and the indoor part 20 are completely disconnected, the airflow at the air outlet of the indoor fan 22 cannot enter the outdoor side through the gas circulation part, the airflow sucked by the centrifugal fan blade of the indoor fan 22 is completely discharged from the inner side air outlet 26, and at this time, the whole machine is in a normal working mode.

(2) When the radiator 40 has a cooling requirement and the outdoor side is at a low temperature, the air door 70 is in a state of closing the air circulation part, the outdoor side part 10 and the indoor side part 20 are completely disconnected, the air flow at the air outlet of the indoor fan 22 cannot enter the outdoor side part 10 through the air circulation part, the air flow sucked by the centrifugal fan blade of the indoor fan 22 is completely discharged from the inner side air outlet 26, and at the moment, the whole machine is in a normal working mode; the centrifugal fan blades of the outdoor fan 11 suck the cold airflow outside the room into the outdoor part 10 through the outside air inlet 13 to dissipate heat of the heat sink 40 and exchange heat with the outdoor heat exchanger 12, and finally discharge the cold airflow outside the room from the outside air outlet 14.

(3) When the heat sink 40 needs cooling and the outdoor side is at high temperature, the active cooling mode is opened, the damper 70 is in a state of opening the gas circulation part, and because positive pressure exists at the air outlet of the volute 23 of the indoor fan 22, and the resistance at the gas circulation part is small, a part of the air flow pushed out by the centrifugal fan blade of the indoor fan 22 flows out to the indoor side through the inner side air outlet 26, and the other part flows to the outdoor side part 10 through the gas circulation part, thereby achieving the purpose of cooling the heat sink 40.

(4) With the cooling demand of the radiator 40 cancelled, the active cooling mode ends, and the damper 70 closes the gas circulation portion.
