Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, and more specifically, to a method for compensating for the temperature difference between the start and stop of an air conditioning compressor, a device for compensating for the temperature difference between the start and stop of an air conditioning compressor, a computer-readable storage medium, a processor, and an air conditioning system. Background Art

[0002] The outdoor air conditioner controller can control the outdoor unit's compressor by comparing the difference between the indoor ambient temperature and the set temperature with the program's stored temperature differential parameters. Typically, these temperature differential parameters are only adjusted during the air conditioner development phase based on the specific export region and are not adjusted again. Alternatively, users can remotely send these temperature differential parameters to compensate for the temperature difference. However, factors such as ambient temperature and the airtightness of the indoor space can affect the heat exchange efficiency between indoor and outdoor. Furthermore, varying heat exchange efficiencies, coupled with the installation location of the indoor air conditioner, can affect the air conditioner's ability to detect the indoor ambient temperature. With so many uncertainties, relying solely on the preset temperature differential parameters may not achieve the desired effect.

[0003] Therefore, there is an urgent need for a temperature difference compensation method for starting and stopping an air-conditioning compressor, which can reasonably control the compressor under different environments. Summary of the Invention

[0034] In this embodiment, a method for compensating for the temperature difference between the start and stop of an air-conditioning compressor running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] Figure 2 FIG is a flow chart of a method for compensating the temperature difference between the start and stop of an air-conditioning compressor according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0036] Step S201: When the air conditioner is turned on, a first duration, a second duration, a third duration, and a fourth duration are obtained, where the first duration and the second duration are any two adjacent operating times of the air conditioner compressor in chronological order, the third duration is the time interval between the start time of the first duration and the previous shutdown time of the first duration, and the fourth duration is the time interval between the end time of the first duration and the start time of the second duration;

[0037] Specifically, after the air conditioner is powered on, the air conditioner compressor starts running. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running, and the second timing variable timer2 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is greater than the startup temperature difference, the air conditioner compressor starts. At this time, timer2 stops timing, and the recorded time is the third time length recorded as t3. At the same time as the air conditioner compressor starts, the first timing variable timer1 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running. At this time, timer1 stops timing, and the recorded time is The time is the first duration and is recorded as t1. When the air-conditioning compressor stops running, timer2 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is greater than the startup temperature difference again, the air-conditioning compressor starts. At this time, timer2 stops timing, and the recorded time is the fourth duration and is recorded as t4. When the air-conditioning compressor starts, timer1 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is less than the shutdown temperature difference again, the air-conditioning compressor stops running. At this time, timing is stopped, and the recorded time is the second duration and is recorded as t2. The units of the above-mentioned first duration, second duration, third duration and fourth duration can be minutes.

[0038] In actual applications, the time from the first shutdown to the first startup of the air conditioner compressor is recorded as t3 after the air conditioner is powered on. Because the uncertainty of the indoor temperature in advance has a greater impact on the compensation method, the time from the first startup to the shutdown of the air conditioner compressor is not recorded here.

[0039] Step S202: Calculate the difference between the second duration and the first duration to obtain a first difference. If the first difference is not within a first predetermined range, adjust the preset shutdown temperature difference of the air-conditioning compressor to obtain a first target shutdown temperature difference. If the difference between the indoor ambient temperature and the air-conditioning set temperature is not greater than the first target shutdown temperature difference, shut down the air-conditioning compressor.

[0040] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the shutdown temperature difference, the air conditioner compressor will shut down. The second time length is compared with the first time length to obtain a first difference. The above-mentioned first predetermined range can be [-3,3]. When the first difference value is within the first predetermined range, it indicates that the time difference between two consecutive startups and shutdowns of the air conditioner compressor is not much, that is, the preset shutdown temperature difference at this time is reasonable, and the temperature of the indoor space can easily reach the set temperature of the air conditioner; if the first difference value is not within the first predetermined range, it means that the time length from the latest startup to shutdown is very different from the time length from the previous startup to shutdown, and the preset shutdown temperature difference needs to be adjusted so that the heat exchange rate between the indoor environment and the outside world is within a reasonable range.

[0041] Step S203, calculate the difference between the above-mentioned fourth time length and the above-mentioned third time length to obtain the second difference, and when the above-mentioned second difference is not within the second predetermined range, adjust the preset start-up temperature difference of the above-mentioned air-conditioning compressor to obtain the first target start-up temperature difference, and when the difference between the above-mentioned indoor ambient temperature and the above-mentioned air-conditioning set temperature is not less than the above-mentioned first target start-up temperature difference, the above-mentioned air-conditioning compressor is turned on.

[0042] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the startup temperature difference, the air conditioner compressor will start up, and the fourth time length is compared with the third time length to obtain a second difference. The above-mentioned second predetermined range can be -3 to 3. When the second difference is within the second predetermined range, it indicates that the time difference between two consecutive shutdowns and startups of the air conditioner compressor is not much, that is, the preset startup temperature difference at this time 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 within the second predetermined range, it means that the time length from the latest shutdown to startup is very different from the time length from the previous shutdown to startup, and the preset startup temperature difference needs to be adjusted so that the heat exchange rate between the indoor environment and the outside world is within a reasonable range.

[0043] Through this embodiment, the above method can adjust the preset shutdown temperature difference and the preset startup temperature difference through the operating time of any two adjacent operations of the air-conditioning compressor and the interval time between the two adjacent operations, thereby avoiding the difference between the indoor ambient temperature and the air-conditioning set temperature being difficult to reach the preset shutdown temperature difference or the preset startup temperature difference due to changes in the space heat exchange efficiency, thereby better maintaining the indoor environment at a constant temperature effect, and thus solving the problem in the prior art that the compressor cannot be reasonably controlled according to the preset startup and shutdown temperature difference under different environments.

[0044] In the specific implementation process, the above step S202 can be implemented by the following steps:

[0045] Step S301: if the first difference is within a third predetermined range, increase the preset shutdown temperature difference by a first predetermined temperature to obtain the first target shutdown temperature difference, and the maximum value of the third predetermined range is less than or equal to the minimum value of the first predetermined range;

[0046] Specifically, the maximum value of the third predetermined range is less than or equal to the minimum value of the first predetermined range, and the first difference is within the third predetermined range, that is, the second time length t2 is much smaller than the first time length t1. At this time, the heat exchange efficiency between the indoor environment and the outside world is low, and the preset shutdown temperature difference can be increased by the first predetermined temperature.

[0047] Step S302, when the above-mentioned first difference is within the fourth predetermined range, the above-mentioned preset shutdown temperature difference is reduced by the second predetermined temperature to obtain the above-mentioned first target shutdown temperature difference, and the minimum value of the above-mentioned fourth predetermined range is greater than or equal to the maximum value of the above-mentioned first predetermined range.

[0048] Specifically, the minimum value of the fourth predetermined range is greater than or equal to the maximum value of the first predetermined range, and the first difference is within the fourth predetermined range, that is, the second time length t2 is much greater than the first time length t1. At this time, due to factors such as environmental changes, the heat exchange efficiency between the indoor environment and the outside world is high, making it more difficult for the indoor environment temperature to reach the air-conditioning set temperature. At this time, the preset shutdown temperature difference can be reduced to the second predetermined temperature. After the next startup, the compressor will not stop until it reaches a lower temperature when cooling or a higher temperature when heating, so that the user can enjoy the temperature before the shutdown for a longer time after the next shutdown when the temperature point is reached.

[0049] In order to make a more precise adjustment to the preset shutdown temperature difference so that the indoor environment can be better maintained at a constant temperature, in some embodiments, step S301 includes: when the above-mentioned first difference is within the first sub-predetermined range, the above-mentioned preset shutdown temperature difference is increased by the first predetermined value, and the maximum value of the above-mentioned first sub-predetermined range is less than or equal to the minimum value of the above-mentioned first predetermined range; when the above-mentioned first difference is within the second sub-predetermined range, the above-mentioned preset shutdown temperature difference is increased by the second predetermined value, the maximum value of the above-mentioned second sub-predetermined range is less than or equal to the minimum value of the above-mentioned first sub-predetermined range, and the above-mentioned second predetermined value is greater than the above-mentioned first predetermined value.

[0050] In order to further adjust the preset shutdown temperature difference more accurately, in some embodiments, step S302 includes: when the above-mentioned first difference is within the third sub-predetermined range, reducing the above-mentioned preset shutdown temperature difference by the third predetermined value, and the minimum value of the above-mentioned third sub-predetermined range is greater than or equal to the maximum value of the above-mentioned first predetermined range; when the above-mentioned first difference is within the fourth sub-predetermined range, reducing the above-mentioned preset shutdown temperature difference by the fourth predetermined value, the minimum value of the above-mentioned fourth sub-predetermined range is greater than or equal to the maximum value of the above-mentioned third sub-predetermined range, and the above-mentioned fourth predetermined value is greater than the above-mentioned third predetermined value.

[0051] In practical applications, 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), and the fourth sub-predetermined range may be (7, +∞). The first and third predetermined values may be 1, and the second and fourth predetermined values may be 2. The first, second, third, and fourth predetermined values are all compensation values for the preset shutdown temperature difference, in degrees Celsius. Therefore, they may be specifically adjusted according to the relationship in Table 1:

[0052] Table 1

[0053]

[0054] In order to adjust the preset startup temperature difference, the above step S203 of the present application can be implemented by the following steps:

[0055] Step S303: if 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, and the maximum value of the fifth predetermined range is less than or equal to the minimum value of the second predetermined range;

[0056] Specifically, the maximum value of the fifth predetermined range is less than or equal to the minimum value of the second predetermined range, and the second difference is within the fifth predetermined range, that is, the fourth time length t4 is much smaller than the third time length t3. At this time, the heat exchange efficiency between the indoor environment and the outside world is relatively high, and the preset startup temperature difference can be reduced by the third predetermined temperature, so that the air-conditioning compressor can start up faster after it stops at the temperature point next time. Faster startup can prevent users from being in an uncomfortable temperature for a long time.

[0057] Step S304, when the second difference is within the sixth predetermined range, the preset startup temperature difference is increased by a fourth predetermined temperature to obtain the first target startup temperature difference, and the minimum value of the sixth predetermined range is greater than or equal to the maximum value of the second predetermined range.

[0058] Specifically, the minimum value of the sixth predetermined range is greater than or equal to the maximum value of the second predetermined range, and the second difference is within the sixth predetermined range, that is, the fourth time length t4 is much greater than the third time length t3. At this time, the heat exchange efficiency between the indoor environment and the outside world is low. At this time, the preset startup temperature difference can be increased by the fourth predetermined temperature.

[0059] In order to make a more precise adjustment to the preset power-on temperature difference so that the indoor environment can be better maintained at a constant temperature, in some embodiments, step S303 includes: when the above-mentioned second difference is within the fifth sub-predetermined range, reducing the above-mentioned preset power-on temperature difference by the fifth predetermined value, and the maximum value of the above-mentioned fifth sub-predetermined range is less than or equal to the minimum value of the above-mentioned second predetermined range; when the above-mentioned second difference is within the sixth sub-predetermined range, reducing the above-mentioned preset power-on temperature difference by the sixth predetermined value, the maximum value of the above-mentioned sixth sub-predetermined range is less than or equal to the minimum value of the above-mentioned fifth sub-predetermined range, and the above-mentioned sixth predetermined value is greater than the above-mentioned fifth predetermined value.

[0060] In order to further adjust the preset power-on temperature difference more accurately, in some embodiments, step S304 includes: when the above-mentioned second difference is within the seventh sub-predetermined range, reducing the above-mentioned preset power-on temperature difference by the seventh predetermined value, and the minimum value of the above-mentioned seventh sub-predetermined range is greater than or equal to the maximum value of the above-mentioned second predetermined range; when the above-mentioned second difference is within the eighth sub-predetermined range, reducing the above-mentioned preset power-on temperature difference by the eighth predetermined value, the minimum value of the above-mentioned eighth sub-predetermined range is greater than or equal to the maximum value of the above-mentioned seventh sub-predetermined range, and the above-mentioned eighth predetermined value is greater than the above-mentioned seventh predetermined value.

[0061] In practical applications, the fifth sub-predetermined range may be [-7, 3), the sixth sub-predetermined range may be (-∞, -7), the seventh sub-predetermined range may be (3, 7), and the eighth sub-predetermined range may be (7, +∞). The fifth and seventh predetermined values may be 1, and the sixth and eighth predetermined values may be 2. The fifth, sixth, seventh, and eighth predetermined values are all compensation values for the preset startup temperature difference, and the unit is degrees Celsius. Therefore, they may be specifically adjusted according to the relationship in Table 2:

[0062] Table 2

[0063]

[0064] Since air conditioners generally have a cooling mode and a heating mode, and the preset shutdown temperature difference and the preset startup temperature difference in the two modes are different, in order to more accurately calculate the compensation value of the preset shutdown temperature difference or the preset startup temperature difference, in some embodiments, after obtaining the first time length, the second time length, the third time length and the fourth time length, the above method also includes: obtaining the current air conditioning mode, the above air conditioning mode is one of the cooling mode and the heating mode; when the above air conditioning mode is the cooling mode, determining the above preset shutdown temperature difference as the preset cooling shutdown temperature difference, and the above preset startup temperature difference as the preset cooling startup temperature difference; when the above air conditioning mode is the heating mode, determining the above preset shutdown temperature difference as the preset heating shutdown temperature difference, and the above preset startup temperature difference as the preset heating startup temperature difference.

[0065] In other embodiments, the method further includes: calculating the difference between the first target shutdown temperature difference and the preset shutdown temperature difference to obtain a third difference; if the third difference is not within the predetermined temperature difference range, determining the second target shutdown temperature difference as the sum of the preset shutdown temperature difference and the maximum value of the predetermined temperature difference range; calculating the difference between the first target startup temperature difference and the preset startup temperature difference to obtain a fourth difference; if the fourth difference is not within the predetermined temperature difference range, determining the second target startup temperature difference as the sum of the preset startup temperature difference and the minimum value of the predetermined temperature difference range. The preset shutdown temperature difference and the preset startup temperature difference are adjusted. If multiple adjustments are made, the values after the multiple adjustments cannot differ too much from the preset values.

[0066] Specifically, the predetermined temperature difference range can be [-2, 2]. After one adjustment, the preset shutdown temperature difference is increased by 1°C. If t2-t1 < -7 is detected, the preset shutdown temperature difference should be increased by another 2°C. That is, the difference between the first target shutdown temperature difference and the preset shutdown temperature difference is 3°C, which exceeds the maximum value of the predetermined temperature difference range of 2°C. Therefore, the second target shutdown temperature difference can only be the preset shutdown temperature difference + 2°C. Similarly, the minimum value can only be -2°C. The algorithm for the second target startup temperature difference is similar to that for the second target shutdown temperature difference and will not be repeated here.

[0067] When the air conditioner encounters a fault or shuts down, all previous compensation values are reset to zero when it is turned on again. In some embodiments, the above method also includes: when the air conditioner is turned on again, the shutdown temperature difference of the air conditioner compressor and the startup temperature difference of the air conditioner compressor are restored to the preset shutdown temperature difference and the preset startup temperature difference respectively.

[0068] Specifically, after the air conditioner is powered on, the start-up and shutdown of the air conditioner compressor are determined according to the preset start-up temperature difference and the preset shutdown temperature difference. Then, the first target shutdown temperature difference and the first target start-up temperature difference are calculated. The subsequent shutdown and startup are determined according to the first target shutdown temperature difference and the first target start-up temperature difference. At the same time, the above-mentioned first time length is refreshed by the above-mentioned second time length, and the above-mentioned third time length is refreshed by the above-mentioned fourth time length. If the air conditioner encounters a fault or is shut down, when the air conditioner is running again, the shutdown and startup of the air conditioner compressor are determined according to the preset shutdown temperature difference and the preset start-up temperature difference.

[0069] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for compensating the temperature difference between the start and stop of the air-conditioning compressor of the present application will be described in detail below with reference to specific embodiments.

[0076] Step S6: when the second difference is within a sixth predetermined range, increasing the preset startup temperature difference by a fourth predetermined temperature;

[0077] Step S7: Obtain the second duration t2;

[0078] Step S8: Calculate the difference between the second duration and the first duration to obtain a first difference, and determine the range of the first difference;

[0079] Step S9: when the first difference is within a third predetermined range, increasing the preset shutdown temperature difference by a first predetermined temperature;

[0080] Step S10: When the first difference is within a fourth predetermined range, reducing the preset shutdown temperature difference by a second predetermined temperature.

[0081] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0082] The embodiment of the present application also provides a device for compensating for the temperature difference between the start and stop of an air-conditioning compressor. It should be noted that the device for compensating for the temperature difference between the start and stop of an air-conditioning compressor in the embodiment of the present application can be used to execute the method for compensating for the temperature difference between the start and stop of an air-conditioning compressor provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation methods, and those that have been explained will not be repeated here. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, implementation in hardware, or a combination of software and hardware, is also possible and conceivable.

[0083] The following introduces the temperature difference compensation device for the start-up and shutdown of the air-conditioning compressor provided in the embodiment of the present application.

[0084] Figure 4 Schematic diagram of a device for compensating for temperature differences between the start and stop of an air-conditioning compressor according to an embodiment of the present application. Figure 4 As shown, the device includes:

[0085] The first acquisition unit 10 is configured to acquire, when the air conditioner is turned on, a first duration, a second duration, a third duration, and a fourth duration, wherein the first duration and the second duration are respectively any two adjacent operating times of the air conditioner compressor in chronological order, the third duration is the time interval between the start time of the first duration and the previous shutdown time of the first duration, and the fourth duration is the time interval between the end time of the first duration and the start time of the second duration;

[0086] Specifically, after the air conditioner is powered on, the air conditioner compressor starts running. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running, and the second timing variable timer2 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is greater than the startup temperature difference, the air conditioner compressor starts. At this time, timer2 stops timing, and the recorded time is the third time length recorded as t3. At the same time as the air conditioner compressor starts, the first timing variable timer1 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running. At this time, timer1 stops timing, and the recorded time is The time is the first duration and is recorded as t1. When the air-conditioning compressor stops running, timer2 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is greater than the startup temperature difference again, the air-conditioning compressor starts. At this time, timer2 stops timing, and the recorded time is the fourth duration and is recorded as t4. When the air-conditioning compressor starts, timer1 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is less than the shutdown temperature difference again, the air-conditioning compressor stops running. At this time, timing is stopped, and the recorded time is the second duration and is recorded as t2. The units of the above-mentioned first duration, second duration, third duration and fourth duration can be minutes.

[0087] In actual applications, the time from the first shutdown to the first startup of the air conditioner compressor is recorded as t3 after the air conditioner is powered on. Because the uncertainty of the indoor temperature in advance has a greater impact on the compensation method, the time from the first startup to the shutdown of the air conditioner compressor is not recorded here.

[0088] a first determining unit 20 configured to calculate a difference between the second duration and the first duration to obtain a first difference, and, if the first difference is not within a first predetermined range, adjust a preset shutdown temperature difference of the air-conditioning compressor to obtain a first target shutdown temperature difference, and shut down the air-conditioning compressor if the difference between the indoor ambient temperature and the air-conditioning set temperature is not greater than the first target shutdown temperature difference;

[0089] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the shutdown temperature difference, the air conditioner compressor will shut down. The second time length is compared with the first time length to obtain a first difference. The above-mentioned first predetermined range can be [-3,3]. When the first difference value is within the first predetermined range, it indicates that the time difference between two consecutive startups and shutdowns of the air conditioner compressor is not much, that is, the preset shutdown temperature difference at this time is reasonable, and the temperature of the indoor space can easily reach the set temperature of the air conditioner; if the first difference value is not within the first predetermined range, it means that the time length from the latest startup to shutdown is very different from the time length from the previous startup to shutdown, and the preset shutdown temperature difference needs to be adjusted so that the heat exchange rate between the indoor environment and the outside world is within a reasonable range.

[0090] The second determination unit 30 is used to calculate the difference between the above-mentioned fourth time length and the above-mentioned third time length to obtain a second difference, and when the above-mentioned second difference is not within the second predetermined range, adjust the preset start-up temperature difference of the above-mentioned air-conditioning compressor to obtain a first target start-up temperature difference, and when the difference between the above-mentioned indoor ambient temperature and the above-mentioned air-conditioning set temperature is not less than the above-mentioned first target start-up temperature difference, the above-mentioned air-conditioning compressor is turned on.

[0091] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the startup temperature difference, the air conditioner compressor will start up, and the fourth time length is compared with the third time length to obtain a second difference. The above-mentioned second predetermined range can be -3 to 3. When the second difference is within the second predetermined range, it indicates that the time difference between two consecutive shutdowns and startups of the air conditioner compressor is not much, that is, the preset startup temperature difference at this time 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 within the second predetermined range, it means that the time length from the latest shutdown to startup is very different from the time length from the previous shutdown to startup, and the preset startup temperature difference needs to be adjusted so that the heat exchange rate between the indoor environment and the outside world is within a reasonable range.

[0092] Through this embodiment, the above-mentioned device can adjust the preset shutdown temperature difference and the preset startup temperature difference through the operating time of any two adjacent operations of the air-conditioning compressor and the interval time between the two adjacent operations, thereby avoiding the difference between the indoor ambient temperature and the air-conditioning set temperature being difficult to reach the preset shutdown temperature difference or the preset startup temperature difference due to changes in the space heat exchange efficiency, thereby better maintaining the indoor environment at a constant temperature effect, and thus solving the problem in the prior art that the compressor cannot be reasonably controlled according to the preset startup and shutdown temperature difference under different environments.

[0093] In a specific implementation process, the first determining unit includes a first processing module and a second processing module, wherein:

[0094] a first processing module, configured to increase the preset shutdown temperature difference by a first predetermined temperature to obtain the first target shutdown temperature difference when the first difference is within a third predetermined range, and the maximum value of the third predetermined range is less than or equal to the minimum value of the first predetermined range;

[0095] Specifically, the maximum value of the third predetermined range is less than or equal to the minimum value of the first predetermined range, and the first difference is within the third predetermined range, that is, the second time length t2 is much smaller than the first time length t1. At this time, the heat exchange efficiency between the indoor environment and the outside world is low, and the preset shutdown temperature difference can be increased by the first predetermined temperature.

[0096] The second processing module is used to reduce the above-mentioned preset shutdown temperature difference by a second predetermined temperature when the above-mentioned first difference is within a fourth predetermined range to obtain the above-mentioned first target shutdown temperature difference, and the minimum value of the above-mentioned fourth predetermined range is greater than or equal to the maximum value of the above-mentioned first predetermined range.

[0097] Specifically, the minimum value of the fourth predetermined range is greater than or equal to the maximum value of the first predetermined range, and the first difference is within the fourth predetermined range, that is, the second time length t2 is much greater than the first time length t1. At this time, due to factors such as environmental changes, the heat exchange efficiency between the indoor environment and the outside world is high, making it more difficult for the indoor environment temperature to reach the air-conditioning set temperature. At this time, the preset shutdown temperature difference can be reduced to the second predetermined temperature. After the next startup, the compressor will not stop until it reaches a lower temperature when cooling or a higher temperature when heating, so that the user can enjoy the temperature before the shutdown for a longer time after the next shutdown when the temperature point is reached.

[0098] In order to make a more precise adjustment to the preset shutdown temperature difference so that the indoor environment can be better maintained at a constant temperature, in some embodiments, the above-mentioned first processing module includes a first processing sub-module and a second processing sub-module, wherein the above-mentioned first processing sub-module is used to increase the above-mentioned preset shutdown temperature difference by a first predetermined value when the above-mentioned first difference is within a first sub-predetermined range, and the maximum value of the above-mentioned first sub-predetermined range is less than or equal to the minimum value of the above-mentioned first predetermined range; the above-mentioned second processing sub-module is used to increase the above-mentioned preset shutdown temperature difference by a second predetermined value when the above-mentioned first difference is within a second sub-predetermined range, and the maximum value of the above-mentioned second sub-predetermined range is less than or equal to the minimum value of the above-mentioned first sub-predetermined range, and the above-mentioned second predetermined value is greater than the above-mentioned first predetermined value.

[0099] In order to further adjust the preset shutdown temperature difference more accurately, in some embodiments, the above-mentioned second processing module includes a third processing sub-module and a fourth processing sub-module, wherein the above-mentioned third processing sub-module is used to reduce the above-mentioned preset shutdown temperature difference by a third predetermined value when the above-mentioned first difference is within a third sub-predetermined range, and the minimum value of the above-mentioned third sub-predetermined range is greater than or equal to the maximum value of the above-mentioned first predetermined range; the above-mentioned fourth processing sub-module is used to reduce the above-mentioned preset shutdown temperature difference by a fourth predetermined value when the above-mentioned first difference is within a fourth sub-predetermined range, and the minimum value of the above-mentioned fourth sub-predetermined range is greater than or equal to the maximum value of the above-mentioned third sub-predetermined range, and the above-mentioned fourth predetermined value is greater than the above-mentioned third predetermined value.

[0100] In practical applications, 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), and the fourth sub-predetermined range may be (7, +∞). The first and third predetermined values may be 1, and the second and fourth predetermined values may be 2. The first, second, third, and fourth predetermined values are all compensation values for the preset shutdown temperature difference, in degrees Celsius. Therefore, they may be specifically adjusted according to the relationship in Table 3:

[0101] Table 3

[0102]

[0103] In order to adjust the preset startup temperature difference, the second determining unit includes a third processing module and a fourth processing module, wherein:

[0104] a third processing module, configured to reduce the preset startup temperature difference by a third predetermined temperature to obtain the first target startup temperature difference when the second difference is within a fifth predetermined range, and the maximum value of the fifth predetermined range is less than or equal to the minimum value of the second predetermined range;

[0105] Specifically, the maximum value of the fifth predetermined range is less than or equal to the minimum value of the second predetermined range, and the second difference is within the fifth predetermined range, that is, the fourth time length t4 is much smaller than the third time length t3. At this time, the heat exchange efficiency between the indoor environment and the outside world is relatively high, and the preset startup temperature difference can be reduced by the third predetermined temperature, so that the air-conditioning compressor can start up faster after it stops at the temperature point next time. Faster startup can prevent users from being in an uncomfortable temperature for a long time.

[0106] The fourth processing module is used to increase the above-mentioned preset startup temperature difference by a fourth predetermined temperature when the above-mentioned second difference is within the sixth predetermined range to obtain the above-mentioned first target startup temperature difference, and the minimum value of the above-mentioned sixth predetermined range is greater than or equal to the maximum value of the above-mentioned second predetermined range.

[0107] Specifically, the minimum value of the sixth predetermined range is greater than or equal to the maximum value of the second predetermined range, and the second difference is within the sixth predetermined range, that is, the fourth time length t4 is much greater than the third time length t3. At this time, the heat exchange efficiency between the indoor environment and the outside world is low. At this time, the preset startup temperature difference can be increased by the fourth predetermined temperature.

[0108] In order to make a more precise adjustment to the preset start-up temperature difference so that the indoor environment can be better maintained at a constant temperature, in some embodiments, the above-mentioned third processing module includes a fifth processing sub-module and a sixth processing sub-module, wherein the above-mentioned fifth processing sub-module is used to reduce the above-mentioned preset start-up temperature difference by a fifth predetermined value when the above-mentioned second difference is within the fifth sub-predetermined range, and the maximum value of the above-mentioned fifth sub-predetermined range is less than or equal to the minimum value of the above-mentioned second predetermined range; the above-mentioned sixth processing sub-module is used to reduce the above-mentioned preset start-up temperature difference by a sixth predetermined value when the above-mentioned second difference is within the sixth sub-predetermined range, and the maximum value of the above-mentioned sixth sub-predetermined range is less than or equal to the minimum value of the above-mentioned fifth sub-predetermined range, and the above-mentioned sixth predetermined value is greater than the above-mentioned fifth predetermined value.

[0109] In order to further adjust the preset power-on temperature difference more accurately, in some embodiments, the above-mentioned fourth processing module includes a seventh processing sub-module and an eighth processing sub-module, wherein the above-mentioned seventh processing sub-module is used to reduce the above-mentioned preset power-on temperature difference by the seventh predetermined value when the above-mentioned second difference is within the seventh sub-predetermined range, and the minimum value of the above-mentioned seventh sub-predetermined range is greater than or equal to the maximum value of the above-mentioned second predetermined range; the above-mentioned eighth processing sub-module is used to reduce the above-mentioned preset power-on temperature difference by the eighth predetermined value when the above-mentioned second difference is within the eighth sub-predetermined range, the minimum value of the above-mentioned eighth sub-predetermined range is greater than or equal to the maximum value of the above-mentioned seventh sub-predetermined range, and the above-mentioned eighth predetermined value is greater than the above-mentioned seventh predetermined value.

[0110] In practical applications, the fifth sub-predetermined range may be [-7, 3), the sixth sub-predetermined range may be (-∞, -7), the seventh sub-predetermined range may be (3, 7), and the eighth sub-predetermined range may be (7, +∞). The fifth and seventh predetermined values may be 1, and the sixth and eighth predetermined values may be 2. The fifth, sixth, seventh, and eighth predetermined values are all compensation values for the preset startup temperature difference, and the unit is degrees Celsius. Therefore, they may be specifically adjusted according to the relationship in Table 4:

[0111] Table 4

[0112]

[0113] Since air conditioners generally have a cooling mode and a heating mode, and the preset shutdown temperature difference and the preset startup temperature difference in the two modes are different, in order to more accurately calculate the compensation value of the preset shutdown temperature difference or the preset startup temperature difference, in some embodiments, the above-mentioned device also includes a second acquisition unit, a third determination unit and a fourth determination unit, wherein the above-mentioned second acquisition unit is used to obtain the current air-conditioning mode after obtaining the first time length, the second time length, the third time length and the fourth time length, and the above-mentioned air-conditioning mode is one of the cooling mode and the heating mode; the above-mentioned third determination unit is used to determine that the above-mentioned preset shutdown temperature difference is the preset cooling shutdown temperature difference, and the above-mentioned preset startup temperature difference is the preset cooling startup temperature difference when the above-mentioned air-conditioning mode is the cooling mode; the above-mentioned fourth determination unit is used to determine that the above-mentioned preset shutdown temperature difference is the preset heating shutdown temperature difference, and the above-mentioned preset startup temperature difference is the preset heating startup temperature difference when the above-mentioned air-conditioning mode is the heating mode.

[0114] In some other embodiments, the apparatus further includes a first calculation unit, a fifth determination unit, a second calculation unit, and a sixth determination unit, wherein the first calculation unit is configured to calculate the difference between the first target shutdown temperature difference and the preset shutdown temperature difference to obtain a third difference; the fifth determination unit is configured to determine, when the third difference is not within the predetermined temperature difference range, that the second target shutdown temperature difference is the sum of the preset shutdown temperature difference and the maximum value of the predetermined temperature difference range; the second calculation unit is configured to calculate the difference between the first target startup temperature difference and the preset startup temperature difference to obtain a fourth difference; and the sixth determination unit is configured to determine, when the fourth difference is not within the predetermined temperature difference range, that the second target startup temperature difference is the sum of the preset startup temperature difference and the minimum value of the predetermined temperature difference range. The preset shutdown temperature difference and the preset startup temperature difference are adjusted. If multiple adjustments are made, the values after the multiple adjustments cannot differ too much from the preset values.

[0115] Specifically, the predetermined temperature difference range can be [-2, 2]. After one adjustment, the preset shutdown temperature difference is increased by 1°C. If t2-t1 < -7 is detected, the preset shutdown temperature difference should be increased by another 2°C. That is, the difference between the first target shutdown temperature difference and the preset shutdown temperature difference is 3°C, which exceeds the maximum value of the predetermined temperature difference range of 2°C. Therefore, the second target shutdown temperature difference can only be the preset shutdown temperature difference + 2°C. Similarly, the minimum value can only be -2°C. The algorithm for the second target startup temperature difference is similar to that for the second target shutdown temperature difference and will not be repeated here.

[0116] When the air conditioner encounters a fault or shuts down, all previous compensation values are reset to zero when it is turned on again. In some embodiments, the above-mentioned device also includes a recovery unit, which is used to restore the shutdown temperature difference and the startup temperature difference of the air conditioner compressor to the preset shutdown temperature difference and the preset startup temperature difference respectively when the air conditioner is restarted.

[0117] Specifically, after the air conditioner is powered on, the start-up and shutdown of the air conditioner compressor are determined according to the preset start-up temperature difference and the preset shutdown temperature difference. Then, the first target shutdown temperature difference and the first target start-up temperature difference are calculated. The subsequent shutdown and startup are determined according to the first target shutdown temperature difference and the first target start-up temperature difference. At the same time, the above-mentioned first time length is refreshed by the above-mentioned second time length, and the above-mentioned third time length is refreshed by the above-mentioned fourth time length. If the air conditioner encounters a fault or is shut down, when the air conditioner is running again, the shutdown and startup of the air conditioner compressor are determined according to the preset shutdown temperature difference and the preset start-up temperature difference.

[0118] The device for compensating for the temperature difference between the start and stop of an air-conditioning compressor includes a processor and a memory. The first acquisition unit, the first determination unit, and the second determination unit are all stored as program units in the memory. The processor executes the program units stored in the memory to implement the corresponding functions. The modules are all located in the same processor; alternatively, the modules can be located in different processors in any combination.

[0119] The processor includes a core, which retrieves the corresponding program unit from the memory. One or more cores can be configured, and by adjusting the core parameters, the problem of not being able to properly control the compressor based on the preset start-stop temperature difference under different environments can be solved.

[0120] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0121] An embodiment of the present invention provides a computer-readable storage medium, which includes a stored program. When the program is running, the device where the computer-readable storage medium is located is controlled to execute the method for compensating the temperature difference between the start and stop of the air-conditioning compressor.

[0122] Specifically, the method for compensating the temperature difference between the start and stop of the air-conditioning compressor includes:

[0123] Step S201: When the air conditioner is turned on, a first duration, a second duration, a third duration, and a fourth duration are obtained, where the first duration and the second duration are any two adjacent operating times of the air conditioner compressor in chronological order, the third duration is the time interval between the start time of the first duration and the previous shutdown time of the first duration, and the fourth duration is the time interval between the end time of the first duration and the start time of the second duration;

[0124] Specifically, after the air conditioner is powered on, the air conditioner compressor starts running. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running, and the second timing variable timer2 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is greater than the startup temperature difference, the air conditioner compressor starts. At this time, timer2 stops timing, and the recorded time is the third time length recorded as t3. At the same time as the air conditioner compressor starts, the first timing variable timer1 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running. At this time, timer1 stops timing, and the recorded time is The time is the first duration and is recorded as t1. When the air-conditioning compressor stops running, timer2 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is greater than the startup temperature difference again, the air-conditioning compressor starts. At this time, timer2 stops timing, and the recorded time is the fourth duration and is recorded as t4. When the air-conditioning compressor starts, timer1 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is less than the shutdown temperature difference again, the air-conditioning compressor stops running. At this time, timing is stopped, and the recorded time is the second duration and is recorded as t2. The units of the above-mentioned first duration, second duration, third duration and fourth duration can be minutes.

[0125] Step S202: Calculate the difference between the second duration and the first duration to obtain a first difference. If the first difference is not within a first predetermined range, adjust the preset shutdown temperature difference of the air-conditioning compressor to obtain a first target shutdown temperature difference. If the difference between the indoor ambient temperature and the air-conditioning set temperature is not greater than the first target shutdown temperature difference, shut down the air-conditioning compressor.

[0126] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the shutdown temperature difference, the air conditioner compressor will shut down. The second time length is compared with the first time length to obtain a first difference. The above-mentioned first predetermined range can be [-3,3]. When the first difference value is within the first predetermined range, it indicates that the time difference between two consecutive startups and shutdowns of the air conditioner compressor is not much, that is, the preset shutdown temperature difference at this time is reasonable, and the temperature of the indoor space can easily reach the set temperature of the air conditioner; if the first difference value is not within the first predetermined range, it means that the time length from the latest startup to shutdown is very different from the time length from the previous startup to shutdown, and the preset shutdown temperature difference needs to be adjusted so that the heat exchange rate between the indoor environment and the outside world is within a reasonable range.

[0127] Step S203, calculate the difference between the above-mentioned fourth time length and the above-mentioned third time length to obtain the second difference, and when the above-mentioned second difference is not within the second predetermined range, adjust the preset start-up temperature difference of the above-mentioned air-conditioning compressor to obtain the first target start-up temperature difference, and when the difference between the above-mentioned indoor ambient temperature and the above-mentioned air-conditioning set temperature is not less than the above-mentioned first target start-up temperature difference, the above-mentioned air-conditioning compressor is turned on.

[0128] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the startup temperature difference, the air conditioner compressor will start up, and the fourth time length is compared with the third time length to obtain a second difference.

[0138] An embodiment of the present invention provides a processor, which is used to run a program, wherein when the program is run, the method for compensating the temperature difference between the start and stop of the air-conditioning compressor is executed.

[0139] Specifically, the method for compensating the temperature difference between the start and stop of the air-conditioning compressor includes:

[0140] Step S201: When the air conditioner is turned on, a first duration, a second duration, a third duration, and a fourth duration are obtained, where the first duration and the second duration are any two adjacent operating times of the air conditioner compressor in chronological order, the third duration is the time interval between the start time of the first duration and the previous shutdown time of the first duration, and the fourth duration is the time interval between the end time of the first duration and the start time of the second duration;

[0141] Specifically, after the air conditioner is powered on, the air conditioner compressor starts running. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running, and the second timing variable timer2 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is greater than the startup temperature difference, the air conditioner compressor starts. At this time, timer2 stops timing, and the recorded time is the third time length recorded as t3. At the same time as the air conditioner compressor starts, the first timing variable timer1 starts timing. When the difference between the indoor ambient temperature difference and the air conditioner set temperature is less than the shutdown temperature difference, the air conditioner compressor stops running. At this time, timer1 stops timing, and the recorded time is The time is the first duration and is recorded as t1. When the air-conditioning compressor stops running, timer2 restarts timing. When the difference between the indoor ambient temperature difference and the air-conditioning set temperature is greater than the startup temperature difference again, the air-conditioning compressor starts. At this time, timer2 stops timing, and the recorded time is the fourth duration and is recorded as t4. When the air-conditioning compressor starts, timer1 restarts timing.

[0142] Step S202: Calculate the difference between the second duration and the first duration to obtain a first difference. If the first difference is not within a first predetermined range, adjust the preset shutdown temperature difference of the air-conditioning compressor to obtain a first target shutdown temperature difference. If the difference between the indoor ambient temperature and the air-conditioning set temperature is not greater than the first target shutdown temperature difference, shut down the air-conditioning compressor.

[0143] Specifically, if the difference between the indoor ambient temperature and the air conditioner set temperature reaches the shutdown temperature difference, the air conditioner compressor will shut down.
