With the difference of the using geographical positions of the air conditioner and the difference of the enclosure structures of the operation places, the operation effects of the air conditioner are also different, for example, the enclosure structures usually select a wall body with better heat preservation effect in the north area of the Yangtze river basin due to relatively lower environmental temperature in winter, the thickness of the wall body is mainly 380mm, the heat leakage of the enclosure structures can be reduced, and the operation frequency of the air conditioner can be properly reduced at the moment; in the area of the Yangtze river basin in the south, the temperature of the environment is relatively high in winter, the requirement on the heat insulation performance of the enclosure structure is low, the thickness of the wall body is mainly 240mm, the condition that the air conditioner operation reaches a set point during the operation period of the air conditioner is easy to occur, but the indoor environment temperature does not reach, and the operation frequency can be properly increased.
In the existing control method of the air conditioner, the room heat leakage quantity in the air conditioner working space is determined according to the current outdoor temperature, room size information, window size information and indoor wall temperature, then the current running frequency of the air conditioner is determined according to the temperature interval where the difference value between the current indoor temperature and the set temperature is located and the room heat leakage quantity, and the air conditioner is controlled to run at the current running frequency, so that the accuracy of indoor temperature regulation is improved. However, in the scheme, the influence of the temperature difference of the indoor and outdoor environments on heat leakage and heat storage of the enclosure structure is not considered, and the problems of reduced comfort and increased energy consumption caused by the difference of cold and heat demands of the air conditioner in different geographical positions due to the difference of the enclosure structure are solved.

According to the self-adaptive control method of the air conditioner, the condition that the building envelope leaks heat or stores heat is judged by acquiring the current change rate of the indoor wall temperature when the indoor environment temperature approaches a stable stage, and when the current change rate is larger than the wall temperature change rate threshold, the building envelope leaks heat or stores heat and changes greatly, reasonable control compensation is needed, energy consumption is reduced, and temperature adjustment comfort is improved.
In a further scheme, the wall temperature change rate threshold is obtained by the following formula: v0=at in+btout+ctc+dtw(i) +e; wherein a, b, c, d, e is a constant, t in is a value of a current indoor environment temperature, t out is a value of a current outdoor environment temperature, t c is a value of a set temperature, and t w(i) is a value of a current indoor wall temperature.
It can be seen that the wall temperature change rate threshold is affected by the current indoor environment temperature, the current outdoor environment temperature, the set temperature, and the current indoor wall temperature, and thus, it is necessary to determine the wall temperature change rate threshold according to the current indoor environment temperature, the current outdoor environment temperature, the set temperature, and the current indoor wall temperature, thereby improving the accuracy of compensation control.

Detailed Description
An embodiment of an adaptive control method of an air conditioner comprises the following steps:
The control method of the air conditioner is an application program applied to the air conditioner and is used for realizing compensation control on the running frequency of the air conditioner according to the heat leakage and heat storage conditions of the enclosure structure.
As shown in fig. 1, when the control method of the air conditioner of the present invention is operated, step S1 is first performed to obtain a current outdoor environment temperature, a current indoor environment temperature and a set temperature. When the air conditioner is started to operate, the air conditioner operates according to a temperature regulation mode and a set temperature set by a user, wherein the temperature regulation mode comprises a refrigeration mode and a heating mode. In order to facilitate the control of the air conditioner to perform temperature adjustment, the current outdoor environment temperature, the current indoor environment temperature and the set temperature need to be acquired for adjustment judgment.
After the current outdoor environment temperature, the current indoor environment temperature and the set temperature are obtained, step S2 is executed to determine whether the absolute value of the first difference between the current outdoor environment temperature and the current indoor environment temperature is greater than a first temperature threshold and the absolute value of the second difference between the current indoor environment temperature and the set temperature is less than or equal to a second temperature threshold. The first temperature threshold and the second temperature threshold may be preset according to experimental data. Under the condition that the temperature difference between the outdoor environment temperature and the indoor environment temperature is large, the heat leakage and the heat storage of the enclosure structure are obvious, so that the condition that the temperature difference between the outdoor environment temperature and the indoor environment temperature is large is determined by comparing the absolute value of the first difference between the current outdoor environment temperature and the current indoor environment temperature with a first temperature threshold value. In order to confirm that the temperature change of the enclosure structure is in a stable state, it is necessary to confirm that the absolute value of the second difference between the current indoor environment temperature and the set temperature is smaller than or equal to the second temperature threshold value, and the indoor environment temperature approaches the stable stage.
If the absolute value of the first difference between the current outdoor environment temperature and the current indoor environment temperature is not satisfied and is greater than the first temperature threshold value, and the absolute value of the second difference between the current indoor environment temperature and the set temperature is less than or equal to the second temperature threshold value, returning to the execution step S1, and continuously acquiring the current outdoor environment temperature, the current indoor environment temperature and the set temperature.
If the absolute value of the first difference between the current outdoor environment temperature and the current indoor environment temperature is larger than the first temperature threshold value and the absolute value of the second difference between the current indoor environment temperature and the set temperature is smaller than or equal to the second temperature threshold value, executing step S3, and obtaining the current change rate of the indoor wall temperature and the wall temperature change rate threshold value. In order to acquire the heat leakage or heat storage condition of the enclosure structure, the judgment is carried out through the current change rate of the indoor wall temperature and the wall temperature change rate threshold value. The indoor wall temperature can be obtained by setting a temperature sensor for detection, and the current change rate of the indoor wall temperature can be obtained by the difference value of the indoor wall temperature in unit time. In this embodiment, the indoor wall temperature at the time of startup and the indoor wall temperature at the current time are obtained, and the difference between the indoor wall temperature at the current time and the indoor wall temperature at the time of startup is divided by the time length from the current time to the time of startup, so as to obtain the current change rate of the indoor wall temperature.
The wall temperature change rate threshold can be preset or obtained in real time according to experimental data. In order to improve the adaptability, the wall temperature change rate threshold value can be obtained in real time, and in this embodiment, the wall temperature change rate threshold value is obtained by the following formula: v0=at in+btout+ctc+dtw(i) +e; wherein a, b, c, d, e is a constant, t in is a value of a current indoor environment temperature, t out is a value of a current outdoor environment temperature, t c is a value of a set temperature, and t w(i) is a value of a current indoor wall temperature. In calculating the wall temperature change rate threshold, the value of the temperature is used for calculation, for example, when the current indoor environment temperature is 20 ℃, the value of the current indoor environment temperature is 20 ℃. The wall temperature change rate threshold is affected by the current indoor environment temperature, the current outdoor environment temperature, the set temperature and the current indoor wall temperature, so in order to improve the accuracy of judgment, the wall temperature change rate threshold needs to be determined according to the current indoor environment temperature, the current outdoor environment temperature, the set temperature and the current indoor wall temperature.
In this embodiment, because the enclosure structures in different geographic locations have differences, for example, differences in thickness of the wall, materials of the wall, etc., and thus different rates of change of the wall temperature exist, the weight coefficients of the current indoor environment temperature, the current outdoor environment temperature, the set temperature and the current indoor wall temperature need to be determined according to different geographic locations, and therefore, the values of a, b, c, d and e are determined according to the geographic location where the air conditioner is currently located. In this embodiment, when the air conditioner is first operated, the geographical position of the air conditioner is determined by obtaining the positioning information, and the map is obtained a, b, c, d and e according to the geographical position. a. The values of b, c, d and e can be set in advance in one-to-one correspondence with the geographic position pairs, and the values of a, b, c, d and e can be obtained through the correspondence when the geographic position is obtained. After the values of a, b, c, d and e are obtained by the primary operation of the air conditioner, the values can be stored so as to facilitate the subsequent operation call and avoid repeated positioning operation.
When the geographical location area where the air conditioner is used is divided, the geographical location where the air conditioner is used can be divided according to different building envelope structures, different envelope structures have different building materials, the thermal physical property parameters of specific building refer to the standard (GB 50176-2016), the geographical location where the air conditioner is used can be divided directly according to the thermal engineering design of the building, and the geographical location can be divided into a severe cold area, a summer hot winter warm area, a mild area (refer to GB 50176-2016) and the like. Of course, the weight coefficients of the current indoor environment temperature, the current outdoor environment temperature, the set temperature and the current indoor wall temperature can also be directly determined according to the enclosure structure, and when the air conditioner is used for the first time, the type of the enclosure structure can be manually input, so that the air conditioner can select the corresponding weight coefficient according to the input type of the enclosure structure.
After the current change rate of the indoor wall temperature and the wall temperature change rate threshold are obtained, executing step S4, and judging that the current change rate is larger than the wall temperature change rate threshold. And comparing the current change rate with a wall temperature change rate threshold value, and determining the heat leakage or heat storage condition of the enclosure structure.
If the current change rate is less than or equal to the wall temperature change rate threshold, executing step S5, and maintaining the current running frequency of the compressor for working. The current change rate is smaller than or equal to the wall temperature change rate threshold, so that the change of heat leakage or heat storage of the building envelope is not large, the current running frequency of the compressor can be maintained to work, and frequency compensation is not needed.
And if the current change rate is greater than the wall temperature change rate threshold, executing step S6, and performing compensation adjustment on the current running frequency of the compressor by a preset amplitude. When the current change rate is greater than the wall temperature change rate threshold, the fact that the heat leakage and heat storage change of the building envelope are large is indicated, reasonable control compensation is needed, energy consumption is reduced, and the comfort of temperature adjustment is improved.
In this embodiment, the step of performing compensation adjustment on the current operating frequency of the compressor with a preset amplitude includes: if the current operation frequency is in the refrigeration state, increasing a preset amplitude on the basis of the current operation frequency; and if the current operation frequency is in the heating state, reducing the preset amplitude on the basis of the current operation frequency. The preset amplitude is preset according to experimental data. When the wall body is in a refrigerating state, the wall body is in a heat leakage state, so that the current running frequency is required to be controlled to be increased by a preset amplitude for compensation, when the wall body is in a heating state, the wall body is in a heat storage state, and certain heat can be released indoors by utilizing the heat stored by the wall body, so that the current running frequency is controlled to be reduced by the preset amplitude for compensation.
In addition, after executing step S1 to obtain the current outdoor environment temperature, the current indoor environment temperature, and the set temperature, the method further includes: and controlling the operation frequency of the compressor and/or controlling the air supply mode according to the first difference absolute value and the second difference absolute value.
In this embodiment, referring to fig. 2, after the current outdoor environment temperature, the current indoor environment temperature and the set temperature are obtained, step S21 is performed to determine whether the absolute value of the first difference is greater than the first temperature threshold. And determining whether the temperature difference between the current outdoor environment temperature and the current indoor environment temperature of the current air conditioner is larger or not through comparison of the first difference absolute value and the first temperature threshold value.
If the absolute value of the first difference is greater than the first temperature threshold, step S22 is executed to determine whether the absolute value of the second difference is less than or equal to the second temperature threshold. If the absolute value of the first difference is larger than the first temperature threshold, the temperature difference between the current outdoor environment temperature and the current indoor environment temperature is larger, so that whether the indoor temperature is close to the set temperature value is further confirmed.
If the absolute value of the second difference is smaller than or equal to the second temperature threshold, step S23 is executed to control the compressor to operate at the first preset frequency, and the air outlet direction is correspondingly controlled according to the cooling mode or the heating mode. The first preset frequency is preset according to experimental data. And the absolute value of the second difference value is smaller than or equal to a second temperature threshold value, so that the indoor environment temperature is close to the set temperature value, at the moment, the compressor is controlled to run at a first preset frequency so as to meet the temperature regulation requirement of the current running stage, and meanwhile, the air outlet direction is correspondingly controlled according to a refrigerating mode or a heating mode, so that the influence on the user experience is avoided. In this embodiment, during the cooling mode, the air outlet direction is controlled to be upward blowing, and during the heating mode, the air outlet direction is controlled to be downward blowing.
If the absolute value of the second difference is greater than the second temperature threshold, step S24 is executed to control the compressor to operate at a second preset frequency and enter a preset fast temperature adjusting air supply mode. The second preset frequency can be preset according to experimental data. If the absolute value of the second difference is larger than the second temperature threshold, the indoor environment temperature is not close to the set temperature value, and the accelerated temperature adjustment is needed, so that the compressor is controlled to operate at a second preset frequency, and a preset rapid temperature adjustment air supply mode is entered. The preset rapid temperature-adjusting air supply mode can be preset by a program developer, for example, by increasing the wind speed of a fan, controlling the air deflector to sweep air up and down, and the like. In this embodiment, the air conditioner is provided with an upper air outlet and a lower air outlet, and the preset rapid temperature-adjusting air supply mode includes: and controlling the upper air outlet and the lower air outlet to supply and sweep air simultaneously.
When step S21 is performed, if the absolute value of the first difference is less than or equal to the first temperature threshold, step S25 is performed to determine whether the absolute value of the second difference is greater than a third temperature threshold, where the third temperature threshold is preset according to experimental data. If the absolute value of the first difference is larger than the first temperature threshold, the temperature difference between the current outdoor environment temperature and the current indoor environment temperature is smaller, so that whether the indoor temperature is close to the set temperature value is further confirmed.
If the absolute value of the second difference is less than or equal to the third temperature threshold, step S26 is executed to turn off the compressor and turn on the air supply mode. The absolute value of the second difference value is smaller than or equal to the third temperature threshold value, so that the indoor temperature is close to the set temperature value, and the difference between the indoor and outdoor ambient temperatures is small, therefore, the compressor can be closed, and the air outlet operation can be performed only by starting the air supply mode, so that the user requirements can be met.
If the absolute value of the second difference is greater than the third temperature threshold, step S27 is executed to control the compressor to operate at a third preset frequency, and enter a preset fast temperature adjusting air supply mode. The absolute value of the second difference is larger than the third temperature threshold, which indicates that the indoor temperature is not close to the set temperature value and the accelerated temperature adjustment is needed, so that the compressor is controlled to operate at the third preset frequency and enter a preset rapid temperature adjustment air supply mode, and the temperature adjustment is accelerated.
It should be noted that, as will be appreciated by those skilled in the art, in order to save the determination process, step S3 in the figure may be performed after step S23.
As can be seen from the above, the adaptive control method of the air conditioner of the present invention determines that the indoor air conditioner has operated for a period of time by the absolute value of the first difference between the current outdoor environment temperature and the current indoor environment temperature being greater than the first temperature threshold and the absolute value of the second difference between the current indoor environment temperature and the set temperature being less than or equal to the second temperature threshold, and determines the heat leakage or heat storage condition of the enclosure by obtaining the current change rate of the indoor wall temperature when the indoor environment temperature approaches the stable stage, and indicates that the heat leakage or heat storage change of the enclosure is greater when the current change rate is greater than the wall temperature change rate threshold, so that reasonable control compensation is required, energy consumption is reduced, and comfort of temperature adjustment is improved.
