[0033] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0034] S101, the air conditioner determines the proportion of the indoor unit's operating load to its maximum indoor unit load.

[0035] S102, the air conditioner controls the compressor's frequency ramp-up rate according to the ratio of the indoor unit's operating load to the indoor unit's maximum load, in order to avoid the frequency ramp-up rate being too fast or too slow.

[0036] The method for controlling an air conditioner provided in this disclosure can control the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load, thereby avoiding an excessively fast or slow ramp-up rate. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, and improving the user experience.

[0037] Optionally, the air conditioner controls the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load. This includes a positive correlation between the air conditioner's compressor frequency ramp-up rate and the ratio of the indoor unit's operating load to its maximum load. Thus, when the indoor unit's operating load is high, the compressor's frequency ramp-up rate is controlled to be faster, allowing the condensing or evaporating temperature to quickly reach the target temperature. When the indoor unit's operating load is low, the compressor's frequency ramp-up rate is controlled to be slower, preventing over-output due to excessively rapid frequency increases, under-output due to compressor slowing down after over-output, and compressor speed increases again after under-output, resulting in cyclical over-output and under-output and fluctuating compressor speed. Controlling the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load avoids excessively fast or slow rate ramp-up. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressure and compressor speed during operation, thus improving the user experience.

[0038] The compressor's frequency ramp-up rate in an air conditioner is positively correlated with the ratio of the indoor unit's operating load to its maximum load. This involves the air conditioner determining a control strategy for the compressor's frequency ramp-up rate based on this ratio, ensuring a positive correlation between the two. The air conditioner then controls the compressor's frequency ramp-up rate according to this strategy. This means that when the indoor unit's operating load is high, the compressor's frequency ramp-up rate is faster to quickly reach the target condensing or evaporating temperature. When the indoor unit's operating load is low, the compressor's frequency ramp-up rate is slower to prevent over-output due to excessively rapid frequency increases, followed by under-output due to compressor deceleration, and then compressor speed increases again, resulting in cyclical over-output and under-output and fluctuating compressor speed. The air conditioner controls the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load to avoid excessively fast or slow rate ramp-up. This allows for a better determination of the compressor's frequency ramp-up rate based on the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thus improving the user experience.

[0039] Optionally, the air conditioner determines the compressor's frequency ramp-up rate control strategy based on the proportion of the indoor unit's operating load to its maximum load. This includes: when the proportion of the indoor unit's operating load to its maximum load is within a first proportional range, the air conditioner uses a first control strategy to determine the compressor's frequency ramp-up rate based on the proportion of the indoor unit's operating load to its maximum load, a correction factor, and the compressor's maximum frequency ramp-up rate. When the proportion of the indoor unit's operating load to its maximum load is within a second proportional range, the air conditioner uses a second control strategy to determine the compressor's frequency ramp-up rate based on the correction factor and the compressor's maximum frequency ramp-up rate. The first proportional range is smaller than the second proportional range. Thus, when the indoor unit's operating load is in the lower first range, the first control strategy, which determines the compressor's frequency ramp-up rate based on the proportion of the indoor unit's operating load to its maximum load, the correction factor, and the compressor's maximum frequency ramp-up rate, controls the compressor's frequency ramp-up rate to be slower. This prevents over-output caused by excessively rapid frequency ramp-up, under-output caused by compressor speed reduction after over-output, under-output caused by compressor speed increase after compressor speed increase, and the compressor's cyclical over-output and under-output, resulting in fluctuating compressor speed. When the indoor unit's operating load is in the higher second range, a second control strategy is implemented, which determines the compressor's frequency ramp-up rate based on a correction factor and the compressor's maximum frequency ramp-up rate. This strategy controls the compressor's frequency ramp-up rate to be faster, allowing the condensing or evaporating temperature to quickly reach the target temperature. The compressor's frequency ramp-up rate is controlled based on the proportion of the indoor unit's operating load to its maximum load, preventing excessively fast or slow ramp-up rates. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, and improving the user experience.

[0040] Optionally, the first proportional interval can be [0, 1). The second proportional interval can be [1, +∞). Thus, when the indoor unit's operating load is higher than its maximum load, the second control strategy, based on the correction coefficient and the compressor's maximum frequency increase rate, determines the compressor's frequency increase rate to be faster, allowing the condensing or evaporating temperature to quickly reach the target temperature. When the indoor unit's operating load is lower than its maximum load, the first control strategy, based on the ratio of the indoor unit's operating load to its maximum load, the correction coefficient, and the compressor's maximum frequency increase rate, determines the compressor's frequency increase rate to be slower. This prevents over-output due to excessively rapid frequency increases, under-output due to compressor deceleration after over-output, under-output due to compressor speed increases after speed increases, and the compressor's cyclical over-output and under-output, resulting in fluctuating compressor speeds. The compressor's frequency increase rate is controlled based on the ratio of the indoor unit's operating load to its maximum load to avoid excessively fast or slow frequency increase rates. This allows for a better determination of the compressor's frequency ramp-up rate based on the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thus improving the user experience.

[0041] Optionally, the air conditioner employs a first control strategy to determine the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load, a correction factor, and the compressor's maximum frequency ramp-up rate. This strategy includes: the air conditioner calculates a = k * A * q / Q. Where a is the compressor's frequency ramp-up rate, k is the correction factor, A is the compressor's maximum frequency ramp-up rate, q is the indoor unit's operating load, Q is the indoor unit's maximum load, and q / Q is the ratio of the indoor unit's operating load to its maximum load. Thus, when the indoor unit's operating load is in a lower first range, the compressor's frequency ramp-up rate a = k * A * q / Q is controlled to be slower, preventing over-output due to excessively rapid frequency ramp-up, under-output due to compressor speed reduction after over-output, and compressor speed increase after under-output, resulting in cyclical over-output and under-output and fluctuating compressor speed. The compressor's frequency ramp-up rate is controlled based on the ratio of the indoor unit's operating load to its maximum load to avoid excessively fast or slow ramp-up rates. This allows for a better determination of the compressor's frequency ramp-up rate based on the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thus improving the user experience.

[0042] Optionally, the air conditioner employs a second control strategy to determine the compressor's frequency ramp-up rate based on a correction coefficient and the compressor's maximum frequency ramp-up rate. This strategy includes calculating a = k * A, where a is the compressor's frequency ramp-up rate, k is the correction coefficient, and A is the compressor's maximum frequency ramp-up rate. Thus, when the indoor unit's operating load is in the higher second range, the compressor's frequency ramp-up rate a = k * A is adjusted to be faster, allowing the condensing or evaporating temperature to quickly reach the target temperature. The compressor's frequency ramp-up rate is controlled based on the proportion of the indoor unit's operating load to its maximum load to avoid excessively fast or slow ramp-up rates. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thereby improving the user experience.

[0043] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0044] S201, the air conditioner determines the proportion of the indoor unit's operating load to its maximum indoor unit load.

[0045] S202, the air conditioner determines k based on Tao.

[0046] S203, the air conditioner determines whether the ratio of the indoor unit's operating load to the indoor unit's maximum load is within the first ratio range.

[0047] S204, when the ratio of the indoor unit's operating load to its maximum load is in the first proportional range, the air conditioner calculates a = k * A * q / Q.

[0048] S205, when the ratio of the indoor unit's operating load to its maximum load is in the second proportional range, the air conditioner calculates a = k * A.

[0049] Wherein, the first proportional interval is smaller than the second proportional interval. 'a' represents the compressor's frequency ramp-up rate, 'k' is the correction coefficient, 'A' is the compressor's maximum frequency ramp-up rate, 'q' is the indoor unit's operating load, 'Q' is the indoor unit's maximum load, 'q / Q' is the ratio of the indoor unit's operating load to its maximum load, and 'Tao' is the outdoor ambient temperature.

[0050] The method for controlling an air conditioner provided in this disclosure can determine a correction coefficient based on the outdoor ambient temperature. When the indoor unit's operating load is in a lower first range, the compressor's frequency ramp-up rate is determined based on the ratio of the indoor unit's operating load to its maximum load, the correction coefficient, and the compressor's maximum frequency ramp-up rate. This controls the compressor's frequency ramp-up rate to be slower, preventing over-output caused by excessively rapid frequency increases, under-output caused by the compressor slowing down after over-output, and subsequent speed increases after under-output, leading to cyclical over-output and under-output and fluctuating compressor speed. When the indoor unit's operating load is in a higher second range, the compressor's frequency ramp-up rate is determined based on the correction coefficient and the compressor's maximum frequency ramp-up rate, controlling the compressor's frequency ramp-up rate to be faster, so that the condensing or evaporating temperature can quickly reach the target temperature. The compressor's frequency ramp-up rate is controlled based on the ratio of the indoor unit's operating load to its maximum load to avoid excessively fast or slow frequency ramp-up rates. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thus improving the user experience.

[0051] Optionally, the air conditioner determines a correction coefficient k based on the outdoor ambient temperature Tao, including: when Tao is in a first temperature range, the air conditioner determines k as a first coefficient value. When Tao is in a second temperature range, the air conditioner determines k based on the linear relationship Tao. When Tao is in a third temperature range, the air conditioner determines k as a second coefficient value. Wherein, the first temperature range is less than the second temperature range, the second temperature range is less than the third temperature range, and the first coefficient value is less than the second coefficient value. Specifically, the value of k can be [0.8, 1]. The air conditioner determines k based on the linear relationship Tao, including: the air conditioner calculates k = 0.004 * Tao + 0.828. The value of the first temperature range can be (-∞, -7℃). The value of the second temperature range can be [-7℃, 43℃]. The value of the third temperature range can be (43℃, +∞). The value of the first coefficient can be 0.8. The value of the second coefficient can be 1. This allows for better determination of the correction factor based on the outdoor ambient temperature, enabling the air conditioner to more accurately control the compressor's frequency ramp-up rate in different geographical environments based on the ratio of the indoor unit's operating load to its maximum load, thus avoiding an excessively fast or slow ramp-up rate. This, in turn, better determines the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thereby improving the user experience.

[0052] Combination Figure 3 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0053] S301, the air conditioner determines the proportion of the indoor unit's operating load to its maximum indoor unit load.

[0054] S302, the air conditioner controls the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load, in order to avoid the frequency ramp-up rate being too fast or too slow.

[0055] S303: When the evaporation temperature reaches the target evaporation temperature Ts, or the condensation temperature reaches the target condensation temperature Td, the air conditioner controls the compressor to stop increasing its frequency.

[0056] The method for controlling an air conditioner provided in this disclosure can control the compressor's frequency ramp-up rate based on the ratio of the indoor unit's operating load to its maximum load, thus avoiding excessively fast or slow ramp-up rates. This allows for better determination of the compressor's frequency ramp-up rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thereby improving the user experience. When the evaporation temperature reaches the target evaporation temperature Ts, or the condensation temperature reaches the target condensation temperature Td, the compressor is controlled to stop ramping up, preventing drastic fluctuations caused by over-output or under-output.

[0057] Optionally, achieving the target evaporation temperature Ts includes: when the air conditioner is operating in cooling mode, determining the saturation pressure Ps corresponding to Ts; controlling the compressor speed according to Ps; and controlling the opening of the indoor unit expansion valve to reach the opening corresponding to the target superheat of the indoor unit expansion valve. Specifically, the determination of Ts includes: the air conditioner determining Ts based on the indoor ambient temperature T. The target superheat of the indoor unit expansion valve can be [3K, 10K]. More specifically, Ts = 1 / 3T - 13 / 3. The value range of T can be [16℃, 43℃]. Thus, when the air conditioner is operating in cooling mode, the air conditioner determines the target evaporation temperature Ts based on the indoor ambient temperature T, controls the compressor speed according to the saturation pressure Ps corresponding to Ts, and controls the opening of the indoor unit expansion valve to reach the opening corresponding to the target superheat of the indoor unit expansion valve, so that the evaporation temperature reaches the target evaporation temperature Ts. If the evaporation temperature reaches the target evaporation temperature Ts, the compressor will be controlled to stop increasing its frequency to avoid drastic fluctuations caused by over-output or under-output of the compressor.

[0058] Optionally, achieving the target condensing temperature Td includes: when the air conditioner is operating in heating mode, controlling the compressor speed according to Td; and controlling the opening of the outdoor unit expansion valve to correspond to the target superheat of the outdoor unit expansion valve. The value of Td can be [35℃, 45℃]. The target superheat of the indoor unit expansion valve can be [5K, 10K]. Thus, when the air conditioner is operating in heating mode, controlling the compressor speed according to Td and controlling the opening of the outdoor unit expansion valve to correspond to the target superheat of the outdoor unit expansion valve, thereby achieving the target condensing temperature Td. If the condensing temperature reaches the target condensing temperature Td, controlling the compressor to stop increasing its frequency to avoid drastic fluctuations caused by over-output or under-output of the compressor.

[0059] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0060] S401, the air conditioner determines the proportion of the indoor unit's operating load to its maximum indoor unit load.

[0061] S402, the air conditioner determines whether the ratio of the indoor unit's operating load to the indoor unit's maximum load is within the first ratio range.

[0062] S403, when the ratio of the indoor unit's operating load to its maximum load is in the first proportional range, the air conditioner calculates a = k * A * q / Q.

[0063] S404, when the ratio of the indoor unit's operating load to its maximum load is in the second proportional range, the air conditioner calculates a = k * A.

[0064] Wherein, the first proportional interval is smaller than the second proportional interval. 'a' represents the compressor's frequency ramp-up rate, 'A' represents the compressor's maximum frequency ramp-up rate, 'q' represents the indoor unit's operating load, 'Q' represents the indoor unit's maximum load, 'q / Q' represents the ratio of the indoor unit's operating load to its maximum load, and 'k' is a correction factor.

[0065] The method for controlling an air conditioner provided in this disclosure can, when the indoor unit's operating load is in a lower first range, determine the compressor's frequency ramp rate based on the proportion of the indoor unit's operating load to its maximum load, a correction coefficient, and the compressor's maximum frequency ramp rate. This controls the compressor's frequency ramp rate to be slower, preventing over-output caused by excessively rapid frequency increases, followed by under-output due to compressor deceleration, and then compressor speed increases again after under-output, resulting in cyclical over-output and under-output and fluctuating compressor speed. When the indoor unit's operating load is in a higher second range, the compressor's frequency ramp rate is determined based on the correction coefficient and the compressor's maximum frequency ramp rate, controlling the compressor's frequency ramp rate to be faster so that the condensing or evaporating temperature can quickly reach the target temperature. The compressor's frequency ramp rate is controlled based on the proportion of the indoor unit's operating load to its maximum load to avoid excessively fast or slow ramp rates. This allows for better determination of the compressor's frequency ramp rate to match the indoor unit's load, preventing drastic fluctuations in suction and discharge pressures and compressor speed during operation, thus improving the user experience.
