Optionally, the temperature t of the surface of the compressor is obtained at the air conditioner 1 Before, firstly, the temperature change rate (temperature change value in unit time) of the compressor temperature or the temperature change difference value of the compressor in a certain time can be used for judging whether the temperature of the compressor reaches a steady state, and after the temperature of the compressor reaches the steady state, the air conditioner acquires the surface temperature t of the compressor 1 And obtaining the maintenance temperature t 1 Time of (tim). Because the temperature of the surface of the compressor is continuously changed, the temperature of the surface of the compressor is obtained after the temperature of the surface of the compressor reaches a steady state, and the accuracy of subsequently determining the temperature in the cavity of the compressor is more facilitated.

tim, and according to the determined preset temperature difference range
Figure 169674DEST_PATH_IMAGE002
tim determines the preheating strength of the compressor; if the condition that the temperature of the outdoor compressor is not needed is determined, the condition that the temperature of the outdoor compressor is proper and the air conditioner is not started for a long time can be met, the heating requirement of a user can be met quickly, the compressor does not need to be preheated, and the preheating strength of the compressor is determined to be 0.
In the embodiment of the disclosure, whether the compressor needs to be preheated is determined according to the outdoor environment temperature and the real-time temperature difference, so as to determine whether the preheating strength of the compressor is 0, that is, whether the compressor needs to be preheated is determined according to the actual condition, thereby ensuring the necessity of preheating the compressor and avoiding the waste of resources. If the compressor needs to be preheated, determining a preset temperature difference range according to the outdoor environment temperature, and determining the preheating strength of the compressor according to the preset temperature difference range, namely, the outdoor environment temperature is different, the preheating strength of the compressor is also different, the suitability of preheating strength selection during the preheating of the compressor is ensured, and the resource waste is further avoided.

If the outdoor environment temperature Tao is less than or equal to 5 ℃, and the real-time temperature difference value
Figure 494345DEST_PATH_IMAGE002
t is less than 20 ℃, which indicates that the outdoor environment temperature is low at the moment or the air conditioner is not started to operate for a long time, so that the compressor needs to be automatically preheated at the moment.
In the embodiment of the disclosure, if the outdoor environment temperature is less than or equal to the preset outdoor temperature value and the real-time temperature difference value is less than the preset difference value, it is determined that the compressor needs to be preheated, that is, the compressor needs to be preheated according to the two parameter conditions, so that the problem of inaccurate confirmation result when confirming according to a single parameter condition is avoided.
Optionally, the determining the preset temperature difference range according to the outdoor environment temperature includes: and the air conditioner acquires a corresponding preset temperature difference range from the correlation relationship between the outdoor environment temperature and the preset temperature difference range according to the outdoor environment temperature Tao. The correlation between the outdoor ambient temperature and the preset temperature difference range includes the corresponding relationship between one or more outdoor ambient temperatures Tao and the preset temperature difference range, as shown in table 1:

TABLE 1
In this embodiment, the correlation relationship between the outdoor environment temperature and the preset temperature difference range includes the corresponding relationship between one or more outdoor environment temperatures and the preset temperature difference range, and the preset temperature difference range corresponding to the outdoor environment temperature can be determined through the correlation relationship between the outdoor environment temperature and the preset temperature difference range, that is, different outdoor environments correspond to different preset temperature difference ranges, so that the preset temperature difference ranges are classified according to the outdoor environment temperature, and the situation that the different outdoor environment temperatures correspond to the same preset temperature difference range to influence the subsequent determination of the preheating parameter is avoided, thereby ensuring the accuracy of the preheating parameter of the compressor.
Optionally, according to the determined preset temperature difference range

Figure 244630DEST_PATH_IMAGE002
And tim, acquiring corresponding preheating power and preheating time from the correlation between the preset temperature difference range and the preheating parameter, so as to preheat the compressor according to the corresponding preheating power and preheating time. The correlation between the preset temperature difference range and the preheating parameter includes the corresponding relationship between one or more preheating temperature difference ranges and the preheating parameter, as shown in table 2:
Figure 768015DEST_PATH_IMAGE004
TABLE 2
Preferably, the low power is 15W and the high power is 30W.
In this embodiment, the correlation between the preset temperature difference range and the preheating parameter includes the corresponding relationship between one or more preset temperature difference ranges and the preheating parameter, and the preheating parameter corresponding to the preset temperature difference range can be determined through the correlation between the preset temperature difference range and the preheating parameter, that is, different preset temperature difference ranges correspond to different preheating parameters, so that the preheating parameters can be classified according to the preset temperature difference ranges, and the problem that the preheating requirement may not be met or energy waste may be caused when the same preheating parameter is used for preheating the compressor is avoided.
Optionally, the determining, by the air conditioner, that the compressor does not need to be preheated according to the outdoor ambient temperature and the real-time temperature difference includes: and if the outdoor environment temperature is greater than the preset outdoor temperature value or the real-time temperature difference value is greater than or equal to the preset difference value, determining that the compressor does not need to be preheated. If the outdoor environment temperature Tao is more than 5 ℃, the outdoor environment temperature is not very low, the outdoor compressor temperature is not very low, when a user starts the machine for heating, the compressor does not need to be preheated for a long time, the heating requirement of the user can be met as soon as possible in a short time, and therefore the compressor does not need to be automatically preheated. Or, if the real-time temperature difference is
Figure 869963DEST_PATH_IMAGE002
t is more than or equal to 20 ℃, which indicates that the temperature in the outdoor compressor cavity is higher, and the outdoor compressor can be started and operated just now, so the compressor does not need to be preheated at the moment.
In the embodiment of the disclosure, if the outdoor ambient temperature is greater than the preset outdoor temperature value, or the real-time temperature difference value is greater than or equal to the preset difference value, it is determined that the compressor does not need to be preheated, that is, only one parameter condition needs to be met when it is determined that the compressor does not need to be preheated, because any parameter condition is met, it indicates that the compressor does not need to be preheated, and both parameter conditions do not need to be met, thereby shortening the time of the determination process.
Optionally, when it is determined that the compressor does not need to be preheated, the air conditioner may provide the user with the warning information through the mobile phone APP. So as to remind the user of the current state of the compressor and further remind the user of the change of the outdoor environment temperature after the user notices.

And S303, if the real-time temperature difference is smaller than the upper limit value of the preset temperature difference range, providing early warning information for the user.
