Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner operation control method, an air conditioner, and a readable storage medium. Background Art

[0002] With the continuous increase of user and test requirements, air conditioners are gradually developing towards the direction of intelligence and multi-functionality. Under this background, in order to meet the requirements of the recent US CVP test, there is an urgent need for a test mode and operation control method that can fit the cooling or heating curve. However, in the existing air conditioner control schemes, there is no control logic for the CVP test. It is impossible to dynamically adjust the power limit value according to the changes in the internal and external loop temperatures and the operation time, and it is difficult to ensure stable fitting to the CVP curve under different working conditions.

[0003] The existing problems are as follows: It is difficult for the existing scheme to dynamically adjust the power limit value according to the internal and external loop temperatures and the operation time, resulting in unstable operation of the air conditioner under different working conditions and inability to fit the CVP cooling or heating curve. Summary of the Invention

[0004] The present invention solves the technical problem that in the existing scheme, it is difficult to dynamically adjust the power limit value according to the internal and external loop temperatures and the operation time, resulting in unstable operation of the air conditioner under different working conditions and inability to fit the CVP cooling and heating curves. The present invention judges the current operation stage of the air conditioner and performs frequency limiting control on the compressor according to the power limit frequency value corresponding to this stage, so that the air conditioner operates stably in accordance with the CVP cooling or heating curve.

[0005] To solve the above problems, the present invention provides an air conditioner operation control method, including: detecting the change data of the internal loop temperature and the change data of the external loop temperature of the air conditioner, and obtaining the set temperature for cooling or heating; judging the current operation stage of the air conditioner according to a plurality of preset temperature stages and the corresponding external loop temperature change conditions; if the current operation stage meets the power limit frequency condition preset for this stage, performing frequency limiting control on the compressor according to the power limit frequency value corresponding to this stage; wherein, the power limit frequency value is determined according to the measured power value corresponding to the nominal capacity of this stage.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By real-time detecting the temperature change data of the inner and outer rings of the air conditioner, the power limit value can be dynamically adjusted, enabling the air conditioner to operate more stably under different working conditions. This adaptive control improves the energy efficiency ratio and enhances the overall performance of the air conditioner. Moreover, by judging the operating stage according to the set temperature and the corresponding outer ring temperature change conditions, the air conditioner can more precisely fit the cooling or heating curve of the CVP, achieving a more accurate temperature control effect. At the same time, by setting multiple preset temperature stages and corresponding conditions, the flexibility of the air conditioner system is increased, enabling it to better adapt to environmental changes. When the preset conditions are met, frequency limiting control is performed on the compressor, enabling it to adjust according to the power frequency limiting value corresponding to the specific operating stage, which can effectively avoid energy consumption waste, reduce the stress of the air conditioner system, and improve the service life of the system.

[0007] In a possible design, the temperature stages of the air conditioner in the cooling mode include: Rated cooling section: In the first cooling cycle, if the initial temperature of the inner ring is the cooling standard value and the outer ring temperature is within the range of plus or minus the first fluctuation value of the first cooling value; and the absolute value of the change in the inner ring temperature is less than or equal to the standard change value, then after the first cooling cycle, the air conditioner executes the P1 power frequency limiting value; Intermediate transition section 1: In the second cooling cycle, if the outer ring temperature continuously drops at the rate of the standard cooling condition, then after the second cooling cycle, the air conditioner executes the P2 power frequency limiting value; Intermediate cooling section: In the third cooling cycle, if the temperature value of the outer ring is always within the range of the second cooling value to the third cooling value, then the air conditioner executes the P2 power frequency limiting value; Intermediate transition section 2: In the fourth cooling cycle, if the outer ring temperature continuously drops at the rate of the standard cooling condition, then after the fourth cooling cycle, the air conditioner executes the P3 power frequency limiting value; Low-temperature cooling section: In the fifth cooling cycle, if the outer ring temperature is within the range of plus or minus the first fluctuation value of the fourth cooling value, then the air conditioner executes the P3 power frequency limiting value.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By clearly dividing multiple temperature stages of the air conditioner in the cooling mode, each stage has specific operating conditions and corresponding power frequency limiting values, enabling precise control of the cooling process and enabling the air conditioner to more precisely fit the cooling curve of the CVP. Moreover, the air conditioner actively adjusts the power frequency limiting value within different cooling cycles, better coping with rapidly changing environmental factors, improving the response speed of the system, and optimizing the energy efficiency performance of the air conditioner. At the same time, corresponding adjustments are made according to different external environmental temperature changes, which enhances the adaptability of the air conditioner in various environments.

[0009] In a possible design, in the rated cooling section, if the absolute value of the change in the inner ring temperature is greater than the standard change value, the compressor of the air conditioner is controlled to stop; if the compressor stops multiple times, then after the first cooling cycle, the air conditioner executes the P1 power frequency limiting value.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: when the absolute value of the change in the inner ring temperature exceeds the standard change value, the compressor is automatically controlled to stop, enabling the inner ring temperature to be stably maintained within the specified range, so that the air conditioner always conforms to the refrigeration curve of CVP. After detecting that the compressor stops multiple times, the air conditioner system will execute the P1 power limit frequency value after the first refrigeration cycle, which can reduce the room temperature fluctuation caused by improper operation of the compressor, thereby improving the safety and reliability of the air conditioner system.

[0011] In a possible design, the P1 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the rated refrigeration condition; the P2 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the intermediate refrigeration condition; the P3 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the low-temperature refrigeration condition.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: clearly defining the power limit frequency values divided by refrigeration conditions enables the air conditioner to quickly switch to the corresponding power level at different refrigeration stages, improving the speed and accuracy of control response. Using the power value corresponding to the nominal capacity as a benchmark can effectively avoid system overload or insufficiency caused by improper power setting, thereby improving the operating stability and lifespan of the air conditioner under different conditions. When the air conditioner system faces external environmental changes, it adjusts the power output in a targeted manner, enhancing the adaptability of the air conditioner under complex climate conditions and ensuring that the air conditioner always operates in accordance with the refrigeration curve of CVP.

[0013] In a possible design, the temperature stages of the air conditioner heating mode include: low-temperature heating stage: in the first heating cycle, if the initial inner ring temperature is the heating standard value and the outer ring temperature is within the range of plus or minus the first fluctuation value of the first heating value; and the absolute value of the change in the inner ring temperature is less than or equal to the standard change value, then after the first heating cycle, the air conditioner executes the P4 power limit frequency value; intermediate transition section three: in the second heating cycle, if the outer ring temperature continuously rises at the rate of the standard heating condition, then after the second heating cycle, the air conditioner executes the P5 power limit frequency value; intermediate heating section: in the third heating cycle, if the temperature value of the outer ring temperature is always within the range of the second heating value to the third heating value, then the air conditioner executes the P5 power limit frequency value; intermediate transition section four: in the fourth heating cycle, if the outer ring temperature continuously rises at the rate of the standard heating condition, then after the fourth heating cycle, the air conditioner executes the P6 power limit frequency value; high-temperature heating stage: in the fifth heating cycle, if the outer ring temperature is within the range of plus or minus the first fluctuation value of the fourth heating value, then the air conditioner executes the P6 power limit frequency value.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By setting different heating cycles and corresponding power limit frequencies, the control accuracy of the air conditioner at each temperature stage is improved, enabling it to more effectively adapt to environmental temperature changes. By setting multiple consecutive temperature stages, the adjustment ability of the system is enhanced, allowing it to flexibly adjust the working mode according to the change of the CVP heating curve, thus better fitting the CVP heating curve and maintaining a stable heating effect. By setting multiple heating stages, the air conditioner can automatically adjust the operation strategy based on real-time temperature data, improving the automation and intelligence level of the air conditioner system.

[0015] In a possible design, in the low-temperature heating section, if the absolute value of the change in the inner-loop temperature is greater than the standard change value, the compressor of the air conditioner is controlled to stop; if the compressor stops multiple times, after the first heating cycle, the air conditioner executes the P4 power limit frequency value.

[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By setting the absolute value of the change in the inner-loop temperature as the condition for the compressor to stop, the inner-loop temperature can be stably maintained within the specified range, so that the air conditioner always fits the CVP heating curve. The mechanism of executing the P4 power limit frequency value after the compressor stops multiple times enables the system to gradually adapt to the new environment in an unstable state, ensuring the stability of the heating operation and reducing unnecessary fluctuations in the system.

[0017] In a possible design, the P4 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the low-temperature heating condition; the P5 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the intermediate heating condition; the P6 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the high-temperature heating condition.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By clearly defining the power limit frequency values under different heating conditions, the air conditioner system can accurately adjust the operating power of the compressor according to the current working state, ensuring its operation at the nominal capacity and giving full play to its performance. The system sets power limit frequency values respectively under the low-temperature, intermediate, and high-temperature heating conditions, enabling it to more specifically respond to different environmental conditions and enhancing the adaptability of the air conditioner to external environmental changes.

[0019] In a possible design, if the current operating stage meets the power frequency limit condition preset for this stage, then frequency limit control is performed on the compressor according to the power frequency limit value corresponding to this stage, where the power frequency limit value is determined according to the measured power value corresponding to the nominal capacity of this stage. It can be replaced with: If the current operating stage meets the frequency frequency limit condition preset for this stage, then frequency limit control is performed on the compressor according to the frequency frequency limit value corresponding to this stage; where the frequency frequency limit value is determined according to the measured frequency value corresponding to the nominal capacity of this stage.

[0020] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: replacing power frequency limit control with frequency frequency limit control enables the system to adjust within a finer frequency range, better adapting to the actual requirements under different working conditions, thereby enhancing the flexibility of the system. Moreover, combining the frequency frequency limit value with the measured frequency value corresponding to the nominal capacity can more accurately reflect the actual operating requirements of the compressor and improve the control accuracy of the system.

[0021] In a possible design, if the current operating stage meets the power frequency limit condition preset for this stage, then frequency limit control is performed on the compressor according to the power frequency limit value corresponding to this stage, where the power frequency limit value is determined according to the measured power value corresponding to the nominal capacity of this stage. It can be replaced with: If the current operating stage meets the current frequency limit condition preset for this stage, then frequency limit control is performed on the compressor according to the current frequency limit value corresponding to this stage; where the current frequency limit value is determined according to the measured current value corresponding to the nominal capacity of this stage.

[0022] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By using current frequency limit control, the system can keep the compressor in the best working state under different load conditions, reduce energy consumption, and improve the power utilization efficiency. Moreover, current frequency limit control can adapt to load changes faster, and compared with power control, the real-time adjustment response is more rapid, improving the system response speed and working efficiency.

[0023] In a possible design, during the operation process of the operation control method, it is necessary to keep the air conditioner running continuously, and the indoor fan speed is fixed in the strong wind mode; where in the cooling mode, the indoor loop temperature is set to the cooling standard value; in the heating mode, the indoor loop temperature is set to the heating standard value.

[0024] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: keeping the air conditioner running continuously and fixing the indoor unit air volume at the strong wind mode helps to ensure the stability of the indoor environmental temperature, enabling the air conditioner to always operate in line with the cooling or heating curve of the CVP during the entire cooling or heating process. Moreover, the combination of continuous operation and the strong wind mode can optimize the energy efficiency ratio of the air conditioner, reduce the energy consumption caused by temperature fluctuations while reaching the set temperature, thereby effectively reducing the operating cost. At the same time, fixing the indoor unit air volume at the strong wind mode is conducive to enhancing the operating stability of the system and reducing the unevenness of cooling and heating caused by air volume fluctuations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings.

[0031] SeeFigures 1 to 5 , the present invention provides an air conditioner operation control method, including: detecting the inner loop temperature change data and the outer loop temperature change data of the air conditioner, and obtaining the cooling or heating set temperature; judging the current operation stage of the air conditioner according to a plurality of preset temperature stages and the corresponding outer loop temperature change conditions; if the current operation stage meets the power frequency limiting condition preset for this stage, then performing frequency limiting control on the compressor according to the power frequency limiting value corresponding to this stage; wherein, the power frequency limiting value is determined according to the measured power value corresponding to the nominal capacity of this stage.

[0032] Specifically, in this embodiment, the air conditioner operation control method is mainly used to meet the CVP (Control Verification Procedure) test mode; the CVP test mode needs to be performed in accordance with the cooling curve and the heating curve. At the same time, the control method of the present application is correspondingly provided with an air conditioner cooling mode and an air conditioner heating mode. Among them, both the air conditioner cooling mode and the air conditioner heating mode are provided with a plurality of temperature stages, and each temperature stage is preset with a power frequency limiting condition, and frequency limiting control is performed on the temperature stage that reaches the corresponding power frequency limiting condition. The air conditioner judges which temperature stage the current operation stage of the air conditioner belongs to by detecting the inner environment temperature change and the outer environment temperature change, and obtaining the current cooling or heating set temperature. Then, the air conditioner judges whether the current stage meets the power frequency limiting condition preset for this stage according to the operation data of the current operation stage. If it meets, then perform frequency limiting control on the compressor according to the power frequency limiting value corresponding to this stage. If it does not meet, then no frequency limiting control is performed on the compressor.

[0033] In an embodiment of the present application, the temperature stages of the air conditioner cooling mode include: rated cooling section: in the first cooling cycle, if the initial inner loop temperature is the cooling standard value and the outer loop temperature is within the range of plus or minus the first fluctuation value of the first cooling value; and the absolute value of the inner loop temperature change is less than or equal to the standard change value, then after the first cooling cycle, the air conditioner executes the P1 power frequency limiting value; intermediate transition section 1: in the second cooling cycle, if the outer loop temperature continuously drops at the rate of the standard cooling condition, then after the second cooling cycle, the air conditioner executes the P2 power frequency limiting value; intermediate cooling section: in the third cooling cycle, if the temperature value of the outer loop is always within the range of the second cooling value to the third cooling value, then the air conditioner executes the P2 power frequency limiting value; intermediate transition section 2: in the fourth cooling cycle, if the outer loop temperature continuously drops at the rate of the standard cooling condition, then after the fourth cooling cycle, the air conditioner executes the P3 power frequency limiting value; low temperature cooling section: in the fifth cooling cycle, if the outer loop temperature is within the range of plus or minus the first fluctuation value of the fourth cooling value, then the air conditioner executes the P3 power frequency limiting value.

[0034] Specifically, in this embodiment, as Figure 4As shown in the operation line chart of the air conditioner in the cooling mode, there are five temperature stages in the specific setting of the air conditioner cooling mode, namely the rated cooling section, the first intermediate transition section, the intermediate cooling section, the second intermediate transition section, and the low-temperature cooling section. These five temperature stages are carried out in sequence and continuously, and each corresponds to a power limit frequency value.

[0035] Among them, within the rated cooling section, the first cooling cycle is from 0.5 hours to 1.5 hours, the cooling standard value is 80°F, the first cooling value is 95°F, the first fluctuation value is 1°F, and the standard change value is 2°C; if the initial temperature of the inner ring temperature of the air conditioner is 80°F, the outer ring temperature is always within the range of 95°F with a deviation not exceeding ±1°F, and the change rate of the inner ring temperature within the first cooling cycle is always less than or equal to 2°C, then after the first cooling cycle, the air conditioner will execute the P1 power limit frequency value. Power limit frequency means setting a power limit frequency value, and the operating power of the air conditioner cannot exceed this power value. If it exceeds, the compressor frequency will be reduced.

[0036] Within the first intermediate transition section, the standard temperature drop condition is 1°F every 15 minutes, and the second cooling cycle is from 0.5 hours to 1 hour; within this temperature stage, the outer ring temperature decreases at a rate of 1°F every 15 minutes, causing the temperature to decrease over time; if the air conditioner can continuously operate for the second cooling cycle at this rate of temperature drop, then after the second cooling cycle, the air conditioner will execute the P2 power limit frequency value. If the continuous operating time at this rate of temperature drop is less than the second cooling cycle, the air conditioner will not execute the P2 power limit frequency value.

[0037] Within the intermediate cooling section, the second cooling value is 79°F, and the third cooling value is 85°F. If within the third cooling cycle, the outer ring temperature of the air conditioner is always within the range of 79°F to 85°F, the air conditioner will execute the P2 power limit frequency value.

[0038] Within the second intermediate transition section, the fourth cooling cycle is from 0.5 hours to 1 hour. Within this temperature stage, the outer ring temperature decreases at a rate of 1°F every 15 minutes, causing the temperature to decrease over time; if the air conditioner can continuously operate for the fourth cooling cycle at this rate of temperature drop, then after the fourth cooling cycle, the air conditioner will execute the P3 power limit frequency value. If the continuous operating time at this rate of temperature drop is less than the fourth cooling cycle, the air conditioner will not execute the P3 power limit frequency value.

[0039] Within the low-temperature cooling section, the fourth cooling value is 67°F. If within the fifth cooling cycle, the outer ring temperature of the air conditioner is always within the range of 67°F with a deviation not exceeding ±1°F, the air conditioner will execute the P3 power limit frequency value; otherwise, the air conditioner will not execute the P3 power limit value.

[0040] In an embodiment of the present application, within the rated cooling section, if the absolute value of the change in the inner ring temperature is greater than the standard change value, the compressor of the air conditioner is controlled to stop; if the compressor stops multiple times, after the first cooling cycle, the air conditioner will execute the P1 power limit frequency value.

[0041] Specifically, in the rated refrigeration section, if the change rate of the inner ring temperature within the first refrigeration cycle is greater than 2°C and the compressor reaches the temperature shutdown multiple times, then after the first refrigeration cycle, the air conditioner also executes the P1 power limit frequency value; in other cases, the air conditioner does not execute the P1 power limit frequency value.

[0042] In an embodiment of the present application, the P1 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the rated refrigeration condition; the P2 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the intermediate refrigeration condition; the P3 power limit frequency value is the power value when the actual capacity is equal to the nominal capacity under the low-temperature refrigeration condition.

[0043] Specifically, the P1 power limit frequency value: the power value corresponding to the rated refrigeration condition where the inner and outer sides have the same temperature and the running actual capacity is equal to the nominal capacity. The P2 power limit frequency value: the power value corresponding to the intermediate refrigeration condition where the inner and outer sides have the same temperature and the running actual capacity is equal to the nominal capacity. The P3 power limit frequency value: the power value corresponding to the low-temperature refrigeration condition where the inner and outer sides have the same temperature and the running actual capacity is equal to the nominal capacity.

[0044] In an embodiment of the present application, the temperature stages of the air conditioner heating mode include: low-temperature heating section: within the first heating cycle, if the initial temperature of the inner ring is the heating standard value and the outer ring temperature is within the range of plus or minus the first fluctuation value of the first heating value; and the absolute value of the change in the inner ring temperature is less than or equal to the standard change value, then after the first heating cycle, the air conditioner executes the P4 power limit frequency value; intermediate transition section three: within the second heating cycle, if the outer ring temperature continuously rises at the rate of the standard heating condition, then after the second heating cycle, the air conditioner executes the P5 power limit frequency value; intermediate heating section: within the third heating cycle, if the temperature value of the outer ring is always within the range of the second heating value to the third heating value, then the air conditioner executes the P5 power limit frequency value; intermediate transition section four: within the fourth heating cycle, if the outer ring temperature continuously rises at the rate of the standard heating condition, then after the fourth heating cycle, the air conditioner executes the P6 power limit frequency value; high-temperature heating section: within the fifth heating cycle, if the outer ring temperature is within the range of plus or minus the first fluctuation value of the fourth heating value, then the air conditioner executes the P6 power limit frequency value.

[0045] Specifically, in this embodiment, as Figure 5 shown in the operation broken line diagram of the air conditioner heating mode, the air conditioner heating mode is specifically set with five temperature stages, namely the low-temperature heating section, the intermediate transition section three, the intermediate heating section, the intermediate transition section four, and the high-temperature heating section. These five temperature stages are carried out in sequence and continuously, and each corresponds to a power limit frequency value.

[0046] Among them, in the low-temperature heating section, the first heating cycle is from 0.25 hours to 1 hour, the heating standard value is 70°F, the first heating value is 17°F, the first fluctuation value is 1°F, and the standard change value is 2°C; if the initial temperature of the inner loop temperature of the air conditioner is 70°F, the outer loop temperature is always within the range of 17°F with a deviation not exceeding ±1°F, and the change rate of the inner loop temperature within the first heating cycle is always less than or equal to 2°C, then after the first heating cycle, the air conditioner will execute the P4 power limit frequency value.

[0047] In the middle transition section three, the standard temperature rise condition is 1°F every 15 minutes, and the second heating cycle is from 0.5 hours to 1 hour; within this temperature stage, the outer loop temperature rises at a rate of 1°F every 15 minutes, causing the temperature to rise over time; if the air conditioner can continuously operate for the second heating cycle at this rising rate, then after the second heating cycle, the air conditioner will execute the P5 power limit frequency value. If the continuous operation time at this rising rate is less than the second heating cycle, the air conditioner will not execute the P5 power limit frequency value.

[0048] In the middle heating section, the second heating value is 33°F, and the third heating value is 39°F. If within the third heating cycle, the outer loop temperature of the air conditioner is always within the range of 33°F to 39°F, then the air conditioner will execute the P5 power limit frequency value.

[0049] In the middle transition section four, the fourth heating cycle is from 0.5 hours to 1 hour. Within this temperature stage, the outer loop temperature rises at a rate of 1°F every 15 minutes, causing the temperature to rise over time; if the air conditioner can continuously operate for the fourth heating cycle at this rising rate, then after the fourth heating cycle, the air conditioner will execute the P6 power limit frequency value. If the continuous operation time at this rising rate is less than the fourth heating cycle, the air conditioner will not execute the P6 power limit frequency value.

[0050] In the high-temperature heating section, the fourth heating value is 47°F. If within the fifth heating cycle, the outer loop temperature of the air conditioner is always within the range of 47°F with a deviation not exceeding ±1°F, the air conditioner will execute the P6 power limit frequency value; otherwise, the air conditioner will not execute the P6 power limit value.

[0051] In an embodiment of the present application, in the low-temperature heating section, if the absolute value of the change in the inner loop temperature is greater than the standard change value, the compressor of the air conditioner is controlled to stop; if the compressor stops multiple times, then after the first heating cycle, the air conditioner will execute the P4 power limit frequency value.

[0052] Specifically, in the low-temperature heating section, if the change rate of the inner loop temperature within the first heating cycle is greater than 2°C, and the compressor reaches the temperature stop multiple times, then after the first heating cycle, the air conditioner will also execute the P4 power limit frequency value. In other cases, the air conditioner will not execute the P4 power limit frequency value.

[0053] In one embodiment of the present application, the P4 power limit frequency value is the power value when the actual capacity is equal to the rated capacity under the low-temperature heating condition; the P5 power limit frequency value is the power value when the actual capacity is equal to the rated capacity under the intermediate heating condition; the P6 power limit frequency value is the power value when the actual capacity is equal to the rated capacity under the high-temperature heating condition.

[0054] Specifically, the P4 power limit frequency value: when the temperature of the inner and outer sides is the same under the low-temperature heating condition and the actual operating capacity is equal to the rated capacity, the corresponding power value. The P5 power limit frequency value: when the temperature of the inner and outer sides is the same under the intermediate heating condition and the actual operating capacity is equal to the rated capacity, the corresponding power value. The P6 power limit frequency value: when the temperature of the inner and outer sides is the same under the high-temperature heating condition and the actual operating capacity is equal to the rated capacity, the corresponding power value.

[0055] In one embodiment of the present application, if the current operating stage meets the power limit frequency condition preset for this stage, then the compressor is controlled for frequency limiting according to the power limit frequency value corresponding to this stage, where the power limit frequency value is determined according to the measured power value corresponding to the rated capacity of this stage. It can be replaced with: If the current operating stage meets the frequency limit condition preset for this stage, then the compressor is controlled for frequency limiting according to the frequency limit value corresponding to this stage; where the frequency limit value is determined according to the measured frequency value corresponding to the rated capacity of this stage.

[0056] Specifically, in this embodiment, power limit frequency can be replaced with frequency limit, and P1 to P6 are changed to frequency limit values, that is, the maximum frequency of the air conditioner operation shall not exceed the corresponding frequency limit value. Among them, the value of the frequency limit value corresponds to the frequency value when the temperature of the inner and outer sides is the same in the corresponding temperature stage and the actual operating capacity is equal to the rated capacity.

[0057] In one embodiment of the present application, if the current operating stage meets the power limit frequency condition preset for this stage, then the compressor is controlled for frequency limiting according to the power limit frequency value corresponding to this stage, where the power limit frequency value is determined according to the measured power value corresponding to the rated capacity of this stage. It can be replaced with: If the current operating stage meets the current limit frequency condition preset for this stage, then the compressor is controlled for frequency limiting according to the current limit frequency value corresponding to this stage; where the current limit frequency value is determined according to the measured current value corresponding to the rated capacity of this stage.

[0058] Specifically, in this embodiment, power limit frequency can be replaced with current limit frequency, and P1 to P6 are changed to current limit frequency values, that is, the maximum current of the air conditioner operation shall not exceed the corresponding current limit frequency value. Among them, the value of the current limit frequency value corresponds to the current value when the temperature of the inner and outer sides is the same in the corresponding temperature stage and the actual operating capacity is equal to the rated capacity.
