Specifically, when the air conditioner receives a test operation command, before the air conditioner is controlled to enter a test operation mode (a test operation heating mode or a test operation cooling mode), whether the indoor environment temperature is smaller than a first preset temperature value or larger than a third preset temperature value is judgedWhether the temperature value or the outdoor environment temperature is smaller than the first preset temperature value or larger than the third preset temperature value is judged, namely whether T is metInner ring< T1, or TInner ring> T3, or TOuter ring< T1, or TOuter ringIf the indoor environment temperature is greater than T3, if the indoor environment temperature is smaller than the first preset temperature value or greater than the third preset temperature value, or the outdoor environment temperature is smaller than the first preset temperature value or greater than the third preset temperature value, step S104 is executed, and the air conditioner does not work. If it is determined that the indoor ambient temperature is greater than or equal to the first preset temperature value and less than or equal to the third preset temperature value, and the outdoor ambient temperature is greater than or equal to the first preset temperature value and less than or equal to the third preset temperature value, the air conditioner is controlled to enter a test operation mode (step S110). If the indoor environment temperature is judged to be smaller than the first preset temperature value or larger than the third preset temperature value, or the outdoor environment temperature is judged to be smaller than the first preset temperature value or larger than the third preset temperature value, the environment temperature is too low or too high and is not in the environment temperature range where the air conditioner can work, and the air conditioner does not work.

Specifically, before executing the control logic (step S120) corresponding to the trial operation mode (trial operation heating mode or trial operation cooling mode), it is determined whether to shift to the trial operation heating mode after executing the trial operation cooling mode or to shift to the trial operation cooling mode after executing the trial operation heating mode. If the test run refrigeration mode is executed and then the test run heating mode is shifted to, or the test run refrigeration mode is executed and then the test run heating mode is shifted to, step S120 is executed. If the test run heating mode is not executed and then the test run cooling mode is switched to, or the test run cooling mode is not executed and then the test run heating mode is switched to, step S114 is executed.
If the trial-run refrigeration mode is executed and then the trial-run heating mode is shifted to, or the trial-run refrigeration mode is executed and then the trial-run refrigeration mode is shifted to, it indicates that the compressor is started, the compressor is not difficult to start again, and the compressor is not required to be started for preheating or electric heating for heating, then step S120 is executed. If the test operation heating mode is not executed and then the test operation cooling mode is shifted to, or the test operation heating mode is not executed and then the test operation cooling mode is shifted to, it indicates that the compressor is not started, and it needs to further determine whether to start the preheating of the compressor or start the electric heating device of the compressor, that is, step S114 is executed.
And step S114, determining whether to start the preheating of the compressor or start the electric heating device of the compressor according to whether the outdoor environment temperature is less than a fourth preset temperature value.
Specifically, if the test operation heating mode is not executed and then the test operation cooling mode is shifted to, or the test operation cooling mode is not executed and then the test operation heating mode is shifted to, whether the outdoor environment temperature is lower than a fourth preset temperature or not is judgedValue, i.e. whether T is satisfiedOuter ringIf the current time is less than T4, the preheating of the compressor is determined to be started or the electric heating device of the compressor is started, and if the current time is not less than T4, the step S120 is directly executed. Wherein, T4 is a fourth preset temperature value which can be selected according to different air conditioners and compressors, preferably-5-0 ℃, if T is satisfiedOuter ring< T4, which indicates that the environment temperature is very low, the lubricating oil of the compressor is easy to freeze, the compressor is very easy to start badly or can not start, and the compressor needs to be heated first to ensure the normal start of the compressor.
Step S116, if the preheating of the compressor or the electric heating device of the compressor is determined to be started, the preheating of the compressor or the electric heating device of the compressor is started for presetting the heating time.
That is, after the preheating of the compressor is started or the electric heating device of the compressor is started for the preset heating time, the set control logic corresponding to the trial operation heating mode or the trial operation cooling mode is executed.
The heating time for starting the preheating of the compressor or starting the electric heating point of the compressor can be selected according to the outdoor environment temperature, different air conditioners or compressors and heating effects, for example, a corresponding relation table of the outdoor environment temperature and the heating time can be preset, the corresponding preset heating time can be obtained by searching the corresponding relation table according to the actual outdoor environment temperature, for example, the corresponding relation table can refer to table 3, the heating time Y selects different heating times N1, N2 and N3 according to the outdoor environment temperature interval, wherein N1 is more than N2 and is more than N3;
Touter ring(℃) N (minutes)
(-5,0] N1
(-10,-5] N2
[-15,-10] N3

It should be understood that table 3 is only an example, the heating time is not limited to the values in table 3, the temperature interval and time can be divided into more fine or shorter intervals according to the actual effect, and the actual heating time is different for different compressors, different preheating of the compressors or electric heating power of the compressors.
The steps S112 to S116 may be executed only in a relatively cold area, and the steps may not be executed, because the ambient temperature is not low and the compressor is not started up without any problem, regardless of the cold area.
