After the power is turned ON, the controller of the outdoor unit 10 of the air conditioner to be tested detects the state of the dial switch, the signal line of the Y compressor and the signal line of the B four-way valve, and if the dial switch, the signal line of the Y compressor and the signal line of the B four-way valve are all in an ON state, the outdoor unit enters a production detection mode, and the outdoor unit is heated and. The frequency of the compressor, the rotating speed of the fan motor, the opening of the electronic expansion valve, the electric heating tape and the like are operated according to settings, the four-way valve is switched on, and the controller of the air-conditioning outdoor unit 10 to be tested forcibly outputs a defrosting signal (the W-C signal line outputs a high level).
3) Turning OFF a dial switch sw1-4, performing cooling operation, and turning OFF the dial switch sw1-4 when the outdoor unit 10 of the air conditioner to be tested runs 120S/130S after the heating operation;
the controller detects the state of the dial switch when the compressor runs for 120S-130S, and if the dial switch is OFF, the operation is switched to a refrigeration mode. The running frequency of the compressor, the rotating speed of the fan motor, the opening degree of the electronic expansion valve, the electric heating belt and the like run according to the setting, the four-way valve is switched off, and the outdoor unit stops outputting defrosting signals (the W-C signal line outputs low level).
In addition, because the four-way valve needs to be disconnected when the heating mode is switched to the cooling mode, in order to ensure that the four-way valve for switching the heating mode to the cooling mode is normally switched, the frequency reduction processing should be firstly performed when the heating mode is switched to the cooling mode, and the four-way valve is controlled to switch the operation mode to operate in the cooling mode when the operation frequency of the compressor is reduced to 25Hz or the frequency reduction time is 30S.
4) And (5) recovering the refrigerant, recovering the refrigerant after the detection index is qualified, and powering off to finish detection.

Secondly, in order to prevent the sw1-4 from forgetting to turn OFF, the detection mode is forcibly exited after the detection state is started for 10min, and the detection mode is changed into normal operation.
(4) The mode switching under the detection state is reliable, the frequency reduction treatment is firstly carried out when the heating mode is converted into the cooling mode, and the four-way valve is switched when the running frequency of the compressor is reduced to 25Hz or the frequency reduction time is 30S, so that the abnormal switching of the four-way valve or the fault shutdown of the four-way valve during the switching can be effectively prevented.
