A control method of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the control method of the air conditioner includes:

acquiring a current operation mode of the air conditioner;

according to the current operation mode and the indoor temperature T_{Inner part}And setting a target temperature T_{Is provided with}Judging whether to set the target temperature T_{Is provided with}Correcting;

if yes, according to the current operation mode and the outdoor temperature T_{Outer cover}And indoor temperatureDegree T_{Inner part}Selecting different correction rules, and calculating the correction target temperature T according to the selected correction rules_{Repair the}；

According to the corrected target temperature T_{Repair the}Determining the actual set temperature T of the air conditioner according to the limit set temperature of the air conditioner_{Fruit of Chinese wolfberry}And controlling a compressor of the air conditioner to match the actual set temperature T_{Fruit of Chinese wolfberry}Is run.

The current operation mode of the air conditioner mainly refers to a heating mode and a cooling mode. Outdoor temperature T_{Outer cover}And indoor temperature T_{Inner part}All are real-time values obtained.

For example, if the current operation mode is a cooling mode and the target temperature T is set_{Is provided with}Less than indoor temperature T_{Inner part}It is determined that the target temperature T is set_{Is provided with}Making a correction if the target temperature T is set_{Is provided with}Not less than indoor temperature T_{Inner part}It is determined not to set the target temperature T_{Is provided with}And (6) correcting.

Setting a target temperature T_{Is provided with}Not less than indoor temperature T_{Inner part}Then, the following may be the case:

indoor temperature T_{Inner part}Has been reduced to a lower temperature by the air conditioner and then the target temperature T will be set_{Is provided with}Adjusted to be higher than the current indoor temperature T_{Inner part}At this time, due to the indoor temperature T_{Inner part}The heat released by the indoor wall and the articles can increase the indoor temperature T instead_{Inner part}Reach the set target temperature T_{Is provided with}To meet the user's demand, so that the set target temperature T does not need to be corrected_{Is provided with}。

Setting a target temperature T_{Is provided with}Less than indoor temperature T_{Inner part}Then, the following may be the case:

setting a target temperature T_{Is provided with}Below the current indoor temperature T_{Inner part}At this time, due to the indoor temperature T_{Inner part}The heat released by the indoor wall and the articles can block the indoor temperature T_{Inner part}Reach the set target temperature T_{Is provided with}Therefore, it is necessary to correct the set target temperature T_{Is provided with}I.e. the actual set temperature T_{Fruit of Chinese wolfberry}Less than the set target temperature T_{Is provided with}So that the air conditioner can provide excessive refrigerating capacity to offset the heat released by indoor wall and article, and the compressor will not be heated by indoor temperature T_{Inner part}Reach the set target temperature T_{Is provided with}The power of the compressor is maintained to be matched with the actual set temperature T by changing the power of the compressor_{Fruit of Chinese wolfberry}So as to reduce the power fluctuation of the compressor and reduce the damage probability of the compressor, and the indoor temperature T_{Inner part}The fluctuation of the user is small, the user requirements can be quickly met, and the user comfort is high.

And, when the user needs the air conditioner to cool because of feeling heat, the compressor of the air conditioner provides more efficient cooling capacity (i.e. the actual set temperature T) in a period of time after the air conditioner is started_{Fruit of Chinese wolfberry}Below a set target temperature T_{Is provided with}) The indoor environment can be relatively cold, the heat on the human body can be more quickly dissipated, and then the power of the compressor is increased to the power required by the user, so that the user feels more comfortable.

The current operation mode is a heating mode, and if a target temperature T is set_{Is provided with}Greater than room temperature T_{Inner part}It is determined that the target temperature T is set_{Is provided with}Making a correction if the target temperature T is set_{Is provided with}Not higher than indoor temperature T_{Inner part}It is determined not to set the target temperature T_{Is provided with}And (6) correcting.

Setting a target temperature T_{Is provided with}Not higher than indoor temperature T_{Inner part}Then, the following may be the case:

indoor temperature T_{Inner part}Has been raised to a higher temperature by the air conditioner, and then the target temperature T will be set_{Is provided with}Adjusted to be lower than the current indoor temperature T_{Inner part}At this time, due to the indoor temperature T_{Inner part}The need for reducing the amount of cold released by the interior walls and articles will, on the contrary, increase the interior temperature T_{Inner part}Reach the set target temperature T_{Is provided with}To meet the user's demand, so that the set target temperature T does not need to be corrected_{Is provided with}。

setting a target temperature T_{Is provided with}Lower than currentIndoor temperature T_{Inner part}At this time, due to the indoor temperature T_{Inner part}The indoor temperature T can be blocked by the cold quantity released by the indoor wall and the articles when the temperature needs to be increased_{Inner part}Reach the set target temperature T_{Is provided with}Therefore, it is necessary to correct the set target temperature T_{Is provided with}I.e. the actual set temperature T_{Fruit of Chinese wolfberry}Greater than a set target temperature T_{Is provided with}So that the air conditioner can provide excessive heating capacity to offset the cold released by indoor wall and article, and the compressor will not produce indoor temperature T_{Inner part}Reach the set target temperature T_{Is provided with}The power of the compressor is maintained to be matched with the actual set temperature T by changing the power of the compressor_{Fruit of Chinese wolfberry}So as to reduce the power fluctuation of the compressor and reduce the damage probability of the compressor, and the indoor temperature T_{Inner part}The fluctuation of the user is small, the user requirements can be quickly met, and the user comfort is high.

And, when the user needs the air conditioner to heat because of feeling cold, the compressor of the air conditioner provides more efficient heating capacity (i.e. the actual set temperature T) for a period of time after the air conditioner is turned on_{Fruit of Chinese wolfberry}Above the set target temperature T_{Is provided with}) The indoor environment is relatively hot, the cold quantity on the human body can be more rapidly dissipated, and then the power of the compressor is reduced to the power required by the user, so that the user feels more comfortable.

If necessary, the set target temperature T is corrected_{Is provided with}According to the current operation mode, the outdoor temperature T_{Outer cover}And indoor temperature T_{Inner part}Selecting different correction rules, and calculating the correction target temperature T according to the selected correction rules_{Repair the}. In other words, after the correction setting target temperature T is determined_{Is provided with}Then, the outdoor temperature T needs to be judged_{Outer cover}For indoor temperature T_{Inner part}I.e. to determine whether the outdoor temperature T needs to be counteracted_{Outer cover}The temperature influence transmitted to the indoor is selected according to the influence, and the power of the compressor is maintained on the basis of offsetting the influence of the outdoor temperature and the temperature released by the indoor wall and articles, so that the energy consumption of the air conditioner is ensured to be low.

In addition, a corrected target temperature T is calculated_{Repair the}Then due to the airThe regulators are generally set to an adjustable temperature range, i.e. a set target temperature T of the air conditioner_{Is provided with}It is required to be not less than the minimum set temperature (e.g., 18 c or 16 c) and not more than the maximum set temperature (e.g., 32 c or 30 c) of the air conditioner, and thus the actual set temperature T_{Fruit of Chinese wolfberry}The determination also needs to refer to the minimum set temperature and the maximum set temperature, wherein the minimum set temperature and the maximum set temperature can be stored in a Data Flash or an EEPROM of a main chip of the air conditioner, or a Flash of a software program, or can be stored in a Data Flash or an EEPROM outside the main chip.

For example, the target temperature T is corrected_{Repair the}If the minimum set temperature is less than the minimum set temperature of the air conditioner, the minimum set temperature of the air conditioner is taken as the actual set temperature T_{Fruit of Chinese wolfberry}(ii) a Correcting the target temperature T_{Repair the}Is higher than the minimum set temperature of the air conditioner and lower than the maximum set temperature of the air conditioner, so as to correct the target temperature T_{Repair the}As the actual set temperature T_{Fruit of Chinese wolfberry}(ii) a Correcting the target temperature T_{Repair the}If the maximum set temperature is higher than the maximum set temperature of the air conditioner, the maximum set temperature of the air conditioner is taken as the actual set temperature T_{Fruit of Chinese wolfberry}. Thus, the actual set temperature T of the air conditioner can be ensured_{Fruit of Chinese wolfberry}The temperature of the air conditioner is always within the limit set temperature range of the air conditioner, so that the phenomenon that the load of a compressor of the air conditioner is overlarge can be avoided, and the compressor is prevented from being stopped or damaged.

As such, the control method of the air conditioner according to the embodiment of the present invention can not only reduce the indoor temperature T_{Inner part}The fluctuation of (2) and the comfort are high, the frequent change of the self power of the compressor can be avoided, and the service life of the compressor is prolonged.

According to some embodiments of the present invention, as shown in FIG. 1, the outdoor temperature T is based on the current operating mode_{Outer cover}And indoor temperature T_{Inner part}Selecting different correction rules, and calculating the correction target temperature T according to the selected correction rules_{Repair the}The method comprises the following steps:

the current operation mode is a refrigeration mode if the outdoor temperature T_{Outer cover}Not less than indoor temperature T_{Inner part}The correction rule is T_{Repair the}＝T_{Is provided with}-KC1(T_{Inner part}-T_{Is provided with}) If the outdoor temperature T_{Outer cover}Less than indoor temperature T_{Inner part}The correction rule is T_{Repair the}＝T_{Is provided with}-KC2(T_{Inner part}-T_{Is provided with}) Wherein KC1 is the first refrigeration correction value and KC2 is the second refrigeration correction value.

In the cooling mode, the outdoor temperature T_{Outer cover}Less than indoor temperature T_{Inner part}Time, outdoor temperature T_{Outer cover}For indoor temperature T_{Inner part}Is promoted when the air conditioner needs to adjust the outdoor temperature T_{Outer cover}The correction requirement of (2) is lower; outdoor temperature T_{Outer cover}Not less than indoor temperature T_{Inner part}Time, outdoor temperature T_{Outer cover}For indoor temperature T_{Inner part}Is suppressed, when the air conditioner needs to cope with the outdoor temperature T_{Outer cover}Is higher, it can be seen that by comparing the outdoor temperature T_{Outer cover}And indoor temperature T_{Inner part}And judging which correction rule is selected, the compressor can be in proper running power, and the indoor temperature T can be avoided_{Inner part}Fluctuating without causing the indoor temperature T_{Inner part}Too low and the energy consumption of the air conditioner is low.

The current operation mode is a heating mode if the outdoor temperature T_{Outer cover}Not higher than indoor temperature T_{Inner part}The correction rule is T_{Repair the}＝T_{Is provided with}+KH1(T_{Is provided with}-T_{Inner part}) If the outdoor temperature T_{Outer cover}Greater than room temperature T_{Inner part}The correction rule is T_{Repair the}＝T_{Is provided with}+KH2(T_{Is provided with}-T_{Inner part}) Wherein KH1 is the first heating correction value and KH2 is the second heating correction value.

In the heating mode, the outdoor temperature T_{Outer cover}Greater than room temperature T_{Inner part}Time, outdoor temperature T_{Outer cover}For indoor temperature T_{Inner part}Is promoted when the air conditioner needs to cope with the outdoor temperature T_{Outer cover}The correction requirement of (2) is lower; outdoor temperature T_{Outer cover}Not higher than indoor temperature T_{Inner part}Time, outdoor temperature T_{Outer cover}For indoor temperature T_{Inner part}Plays a role of inhibiting when the air conditioner needs to keep the outdoor temperature T_{Outer cover}Is higher, it can be seen that by comparing the outdoor temperature T_{Outer cover}And indoor temperature T_{Inner part}And judging which correction rule is selected, the compressor can be in proper running power, and the indoor temperature T can be avoided_{Inner part}Fluctuating without causing the indoor temperature T_{Inner part}Too low and the energy consumption of the air conditioner is low.

The first refrigeration correction value KC1, the second refrigeration correction value KC2, the first heating correction value KH1, and the second heating correction value KH2 may be stored in a Data Flash or an EEPROM of a main chip of the air conditioner, or a Flash of a software program, or may be stored in a Data Flash or an EEPROM outside the main chip.

Specifically, the first refrigeration correction value KC1 is 1.5 to 3, the second refrigeration correction value KC2 is 0.5 to 1.5, the first heating correction value KH1 is 1.5 to 3, and the second heating correction value KH2 is 0.5 to 1.5. Thus, it is ensured that each of the first cooling modification values KC1 is not less than the second cooling modification value KC2, and each of the first heating modification values KH1 is not less than the second heating modification value KH2, which is advantageous for setting the target temperature T_{Is provided with}And the energy consumption of the air conditioner is low, and the indoor temperature T is corrected_{Inner part}The adjustment efficiency is high.

According to some embodiments of the present invention, as shown in FIG. 2, at the actual set temperature T_{Fruit of Chinese wolfberry}After the operation, the method further comprises the following steps: according to the indoor temperature T_{Inner part}The compressor of the air conditioner is controlled to run at different frequencies for different time.

If the target temperature T is set_{Is provided with}Without correction, the compressor of the air conditioner is matched with the set target temperature T_{Is provided with}If the air conditioner is a fixed-frequency air conditioner, the air conditioner is operated at the indoor temperature T_{Inner part}Approaching the set target temperature T_{Is provided with}When the compressor is started, the compressor can be stopped; if the air conditioner is a variable frequency air conditioner, the indoor temperature T is_{Inner part}Approaching the set target temperature T_{Is provided with}At this time, the compressor may be operated at a minimum frequency.

If the target temperature T is set_{Is provided with}Requiring modification of the compressor of the air conditioner to match the actual set temperature T_{Fruit of Chinese wolfberry}Is operated according to the indoor temperature T_{Inner part}Reaches the actual set temperature T_{Fruit of Chinese wolfberry}Time of, or room temperatureT_{Inner part}Reach the set target temperature T_{Is provided with}Time of, or room temperature T_{Inner part}The set target temperature T is not reached within a period of time_{Is provided with}And does not reach the actual set temperature T_{Fruit of Chinese wolfberry}The influence of the air conditioner on the temperature of the current use environment can be calculated, and the next operation frequency and operation time of the compressor of the air conditioner are controlled according to the influence, so that the air conditioner is more adaptive to the current use environment, the applicability of the air conditioner can be improved, and the energy consumption can be reduced.

Other configurations and operations of the control method of the air conditioner according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
