Fig. 2 is a flowchart of a method of compensating for temperature differences in an on-off state of an air conditioner compressor according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step S201, under the condition that an air conditioner is started and operated, acquiring a first time length, a second time length, a third time length and a fourth time length, wherein the first time length and the second time length are respectively two running times of the air conditioner compressor which are arbitrarily adjacent from front to back according to time sequence, the third time length is a time interval between the starting time of the first time length and the previous stopping time of the first time length, and the fourth time length is a time interval between the ending time of the first time length and the starting time of the second time length;

Specifically, after the air conditioner is powered on, the air conditioner compressor starts to operate, under the condition that the difference value between the indoor environment temperature difference and the air conditioner set temperature is smaller than the shutdown temperature difference, the air conditioner compressor stops operating, the second timing variable timer2 starts timing, when the difference value between the indoor environment temperature difference and the air conditioner set temperature is larger than the startup temperature difference, the air conditioner compressor starts, at the moment, the timer2 stops timing, the recorded time is recorded as a third time length to be t3, when the air conditioner compressor starts, the first timing variable timer1 starts timing, under the condition that the difference value between the indoor environment temperature difference and the air conditioner set temperature is smaller than the shutdown temperature difference, the air conditioner compressor stops operating, at the moment, the timer1 stops timing, the recorded time is recorded as a first time length to be t1, when the difference value between the indoor environment temperature difference and the air conditioner set temperature is larger than the startup temperature difference again, at the moment, the timer2 stops timing when the timer2 stops timing is recorded as a fourth time length to be t4, and when the air conditioner stops the time length is longer than the fourth time length to be recorded as the second time length to be the time length to be equal to the time length to the second time length to the time when the difference value between the indoor environment temperature difference and the air conditioner is smaller than the fourth time.

In practical application, the time taken for the air conditioner compressor to stop from the first time to start is recorded as t3 after the air conditioner is powered on, because the uncertainty of indoor temperature has a large influence on the compensation method in advance, and the time from the first time to stop of the air conditioner compressor is not recorded.

Step S202, calculating the difference between the second time length and the first time length to obtain a first difference, and adjusting a preset shutdown temperature difference of the air conditioner compressor to obtain a first target shutdown temperature difference when the first difference is not within a first preset range, and stopping the air conditioner compressor when the difference between the indoor environment temperature and the air conditioner set temperature is not greater than the first target shutdown temperature difference;

specifically, if the difference between the indoor environment temperature and the set temperature of the air conditioner reaches the shutdown temperature difference, the air conditioner compressor is shut down, the second time length is compared with the first time length to obtain a first difference value, the first preset range can be [ -3,3], when the first difference value is in the first preset range, the difference between the continuous two times of starting up and stopping of the air conditioner compressor is not great, that is, the preset shutdown temperature difference at the moment is reasonable, and the temperature of the indoor space can easily reach the set temperature of the air conditioner; if the first difference is not within the first preset range, the time length from the last start-up to the stop is greatly different from the time length from the last start-up to the stop, and the preset stop temperature difference is required to be adjusted, so that the heat exchange rate between the indoor environment and the outside is in a reasonable range.

Step S203, calculating a difference between the fourth duration and the third duration to obtain a second difference, and adjusting a preset starting temperature difference of the air conditioner compressor to obtain a first target starting temperature difference when the second difference is not within a second predetermined range, and starting the air conditioner compressor when the difference between the indoor environment temperature and the air conditioner set temperature is not smaller than the first target starting temperature difference.

Specifically, if the difference between the indoor environment temperature and the set temperature of the air conditioner reaches the starting temperature difference, the air conditioner compressor is started, the fourth time length is compared with the third time length to obtain a second difference value, the second preset range can be-3, when the second difference value is in the second preset range, the time difference from continuous two times of stopping of the air conditioner compressor to starting is not great, that is, the preset starting temperature difference at the moment is reasonable, and the temperature of the indoor space can easily reach the set temperature of the air conditioner; if the second difference is not in the second preset range, the time length from the latest shutdown to the startup is greatly different from the time length from the last shutdown to the startup, and the preset startup temperature difference needs to be adjusted, so that the indoor environment and the external heat exchange rate are in a reasonable range.

According to the method, the preset shutdown temperature difference and the preset startup temperature difference can be adjusted through the running time of any two adjacent air conditioner compressors and the running interval time of the two adjacent air conditioner compressors, the problem that the difference between the indoor environment temperature and the air conditioner set temperature is difficult to reach the preset shutdown temperature difference or the preset startup temperature difference due to the change of the space heat exchange efficiency is avoided, the indoor environment is better maintained at a constant temperature effect, and the problem that the compressors cannot be reasonably controlled according to the preset startup and shutdown temperature differences in different environments in the prior art is solved.

In a specific implementation process, the step S202 may be implemented by the following steps:

specifically, the maximum value of the third predetermined range is smaller than or equal to the minimum value of the first predetermined range, the first difference is within the third predetermined range, that is, the second time period t2 is far smaller than the first time period t1, at this time, the heat exchange efficiency between the indoor environment and the outside is low, and the preset shutdown temperature difference can be increased by the first predetermined temperature.

Step S302, when the first difference is within a fourth predetermined range, the preset shutdown temperature difference is reduced by a second predetermined temperature, and the first target shutdown temperature difference is obtained, wherein the minimum value of the fourth predetermined range is greater than or equal to the maximum value of the first predetermined range.

Specifically, the minimum value of the fourth preset range is greater than or equal to the maximum value of the first preset range, the first difference value is in the fourth preset range, that is, the second time period t2 is far greater than the first time period t1, at this time, the indoor environment and the outside heat exchange efficiency are high due to factors such as environmental change, so that the indoor environment temperature is more difficult to reach the set temperature of the air conditioner, at this time, the preset shutdown temperature difference can be reduced by the second preset temperature, the compressor can be stopped at a temperature point when the compressor reaches a lower temperature after the next startup or reaches a higher temperature when the compressor heats, and a user can enjoy the temperature before the shutdown for a longer time after the next temperature point shutdown.

In order to more precisely adjust the preset shutdown temperature difference, so that the indoor environment is better maintained at a constant temperature, in some embodiments, step S301 includes: increasing the preset shutdown temperature difference by a first preset value under the condition that the first difference value is in a first sub-preset range, wherein the maximum value of the first sub-preset range is smaller than or equal to the minimum value of the first preset range; and when the first difference value is within a second sub-preset range, increasing the preset shutdown temperature difference by a second preset value, wherein the maximum value of the second sub-preset range is smaller than or equal to the minimum value of the first sub-preset range, and the second preset value is larger than the first preset value.

To further more precisely adjust the preset shutdown temperature difference, in some embodiments, step S302 includes: reducing the preset shutdown temperature difference by a third predetermined value when the first difference is within a third sub-predetermined range, wherein the minimum value of the third sub-predetermined range is greater than or equal to the maximum value of the first predetermined range; and when the first difference is within a fourth sub-predetermined range, reducing the preset shutdown temperature difference by a fourth predetermined value, wherein the minimum value of the fourth sub-predetermined range is greater than or equal to the maximum value of the third sub-predetermined range, and the fourth predetermined value is greater than the third predetermined value.

In practice, the first sub-predetermined range may be [ -7, 3), the second sub-predetermined range may be (- + -7), the third sub-predetermined range may be (3, 7), the fourth sub-predetermined range may be (7, ++ -infinity), the first and third predetermined values may be 1, the second predetermined value and the fourth predetermined value may be 2, and the first predetermined value, the second predetermined value, the third predetermined value and the fourth predetermined value are all compensation values for the preset shutdown temperature difference, and the unit is degrees celsius, so that the adjustment can be specifically performed according to the relationship of table 1:

TABLE 1

In order to adjust the preset startup temperature difference, the step S203 of the present application may be implemented by the following steps:

step S303, when the second difference is within a fifth predetermined range, reducing the preset startup temperature difference by a third predetermined temperature to obtain the first target startup temperature difference, wherein the maximum value of the fifth predetermined range is smaller than or equal to the minimum value of the second predetermined range;

specifically, the maximum value of the fifth preset range is smaller than or equal to the minimum value of the second preset range, the second difference value is in the fifth preset range, that is, the fourth time period t4 is far smaller than the third time period t3, at this time, the heat exchange efficiency between the indoor environment and the outside is higher, the preset starting temperature difference can be reduced by the third preset temperature, so that the air conditioner compressor can be started faster after the next temperature point is reached, and the user can be prevented from being at uncomfortable temperature for a long time by the faster starting.

Step S304, when the second difference is within a sixth predetermined range, increasing the preset power-on temperature difference by a fourth predetermined temperature to obtain the first target power-on temperature difference, where a minimum value of the sixth predetermined range is greater than or equal to a maximum value of the second predetermined range.

Specifically, the minimum value of the sixth predetermined range is greater than or equal to the maximum value of the second predetermined range, the second difference value is within the sixth predetermined range, that is, the fourth time period t4 is far greater than the third time period t3, at this time, the heat exchange efficiency between the indoor environment and the outside is low, and at this time, the preset startup temperature difference can be increased by the fourth predetermined temperature.

In order to more precisely adjust the preset power-on temperature difference, so that the indoor environment is better maintained at a constant temperature, in some embodiments, step S303 includes: reducing the preset startup temperature difference by a fifth preset value under the condition that the second difference value is in a fifth preset sub-range, wherein the maximum value of the fifth preset sub-range is smaller than or equal to the minimum value of the second preset range; and when the second difference is within a sixth sub-predetermined range, reducing the preset startup temperature difference by a sixth predetermined value, wherein the maximum value of the sixth sub-predetermined range is smaller than or equal to the minimum value of the fifth sub-predetermined range, and the sixth predetermined value is larger than the fifth predetermined value.

In order to further more precisely adjust the preset power-on temperature difference, in some embodiments, step S304 includes: reducing the preset startup temperature difference by a seventh preset value under the condition that the second difference value is in a seventh preset range, wherein the minimum value of the seventh preset range is larger than or equal to the maximum value of the second preset range; and when the second difference is within an eighth sub-predetermined range, reducing the preset startup temperature difference by an eighth predetermined value, wherein the minimum value of the eighth sub-predetermined range is greater than or equal to the maximum value of the seventh sub-predetermined range, and the eighth predetermined value is greater than the seventh predetermined value.
