When the ambient temperature is high, the indoor fan runs at a low wind speed, resulting in a high air outlet temperature. In this way, the technical solution adopted by the relevant technology cannot effectively overcome the problem of the air outlet temperature being too cold or too hot, and the improvement in the consumer's experience comfort is not significant.

[0037] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0038] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0043] When an air conditioner equipped with an electric heating function turns on the electric heating function for heating operation, the gear of the indoor fan is set with multiple fixed gears, for example, high wind gear, medium wind gear and low wind gear. The fan speeds corresponding to the high wind gear, medium wind gear and low wind gear decrease in sequence. Normally, the high wind gear is used to meet the requirements of the rated capacity of the air conditioner, and the low wind gear is used to meet the requirements of the air conditioner to produce condensation. When the air conditioner has electric heating and cooling requirements, the air conditioner will pre-configure the set gear and control the indoor fan to start running at the set gear. In this way, when the ambient temperature value is low or high, the temperature value of the indoor unit outlet is very likely to be overcooled or overheated, affecting the consumer's experience and comfort.

[0044] The related technology discloses the following technical solution: when the air conditioner is operated in the electric heating mode, the outlet air temperature value is obtained; when the outlet air temperature value is less than the lower temperature threshold, the indoor fan is controlled to operate at a high wind speed. When the outlet air temperature value is greater than the upper temperature threshold, the indoor fan is controlled to operate at a low wind speed.

[0045] However, when the air conditioner is operated in electric heating mode, when the ambient temperature is low, the indoor fan runs at a high wind speed, resulting in a low air outlet temperature. When the ambient temperature is high, the indoor fan runs at a low wind speed, resulting in a high air outlet temperature. In this way, the technical solution adopted by the relevant technology cannot effectively overcome the problem of overcooling or overheating of the air outlet temperature, and the improvement of the consumer's experience comfort is not significant.

[0046] Combination Figure 1 As shown, the air conditioner includes a refrigerant circulation system and an electric heating device 10. The refrigerant circulation system includes a compressor 21, an indoor unit, an outdoor unit, a throttling device 23 and a four-way valve 25. The indoor unit includes an indoor heat exchanger 241 and an indoor fan 242. The outdoor unit includes an outdoor heat exchanger 221 and an outdoor fan 222. When the air conditioner is operated in a cooling mode, cooling is performed through the refrigerant circulation system. When the air conditioner is operated in an electric heating heating mode, heating is performed through the electric heating device 10, and the compressor 21, the outdoor unit, the indoor heat exchanger 241, the throttling device 23 and the four-way valve 25 are all stopped, and the indoor fan 242 is running. At this time, the electric heating device 10 is the only heat source for heating operation. In addition, the characteristic of resistance-type electric heating is that the electric heating power is a constant value, and the electric heating power does not change with the change of air volume.

[0047] According to the heat calculation formula: Q = c × m × ΔT. Among them, c represents the specific heat capacity of air, m represents the circulating air volume of the air conditioner, ΔT represents the temperature change, and Q represents the electric heating power.

[0048] When the electric heating power of the electric heating device 10 of the air conditioner is a constant, that is, Q is a constant. Under normal atmospheric pressure, when the air conditioner is operated in heating mode, the change in the specific heat capacity of the air is extremely small, and the specific heat capacity of the air is approximately a constant. When the speed of the indoor fan of the air conditioner changes, the air volume will change, and ΔT will also change accordingly. In this way, when the changes in Q and c are extremely small, there is an inverse proportional relationship between m and ΔT. In this way, when the air conditioner is operated in heating mode, if the outlet air temperature is too high, the outlet air temperature can be lowered by increasing the circulating air volume. When the air conditioner is operated in heating mode, if the outlet air temperature is too low, the outlet air temperature can be increased by reducing the circulating air volume.

[0049] Based on the above air conditioner structure, combined with Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0050] S01, when the air conditioner is operated in an electric heating mode, the processor obtains the air outlet temperature of the indoor unit, wherein the electric heating power of the electric heating device is a fixed value.

[0051] S02: When the air outlet temperature is lower than the target comfortable temperature, the processor reduces the speed of the indoor fan to increase the air outlet temperature.

[0052] S03: When the air outlet temperature is greater than the target comfort temperature value, the processor increases the speed of the indoor fan to reduce the air outlet temperature.

[0053] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted. When the outlet air temperature is less than the target comfort temperature value, the embodiment of the present disclosure indicates that the outlet air temperature is too low. Because in the electric heating heating mode, the circulating air volume is inversely proportional to the size of the outlet air temperature. Therefore, the embodiment of the present disclosure can achieve the purpose of increasing the outlet air temperature by reducing the speed value of the indoor fan to prevent the outlet air temperature from being too cold. When the outlet air temperature is greater than the target comfort temperature value, it indicates that the outlet air temperature is too high. The embodiment of the present disclosure can achieve the purpose of reducing the outlet air temperature by increasing the speed value of the indoor fan to prevent the outlet air temperature from being overheated. In summary, the embodiment of the present disclosure can adaptively adjust the speed value of the indoor fan according to the size relationship between the outlet air temperature and the target comfort temperature value, so that the adjusted outlet air temperature approaches the target comfort temperature value, prevents the outlet air temperature from being too cold or too hot, and improves the consumer's experience comfort.

[0054] Optionally, combined Figure 3 As shown, the processor reduces the speed value of the indoor fan, including:

[0055] S11, the processor is based on the air outlet temperature and T min The size relationship determines the first proportionality coefficient, T minIndicates the minimum acceptable comfort temperature.

[0056] S12, the processor calculates the air outlet temperature and T min The absolute value of the first temperature difference is determined based on the relationship between the temperature and the target comfort temperature value.

[0057] S13, the processor determines the target speed change rate according to the first proportional coefficient, the absolute value of the first temperature difference and the air outlet area. The absolute value of the temperature difference is positively correlated with the speed change rate. Specifically, the greater the absolute value of the temperature difference, the greater the speed change rate. The smaller the absolute value of the temperature difference, the smaller the speed change rate.

[0058] S14: The processor reduces the speed value of the indoor fan according to the target speed change rate.

[0059] Thus, the embodiment of the present disclosure is based on the outlet air temperature and T min The first proportionality coefficient is determined based on the relationship between the outlet air temperature and T min The first temperature difference absolute value is determined based on the relationship between the outlet air temperature and the target comfort temperature value to obtain the temperature difference corresponding to the outlet air temperature. Finally, the target speed change rate is determined based on the first proportional coefficient, the first temperature difference absolute value and the outlet air area, and the speed value of the indoor fan is reduced according to the target speed change rate. In this way, the disclosed embodiment can set the speed change rate based on the relationship between the outlet air temperature and the minimum acceptable comfort temperature and the target comfort temperature value, the first proportional coefficient and the outlet air area, effectively increase the outlet air temperature value, and make the adjusted outlet air temperature approach the target comfort temperature value, thereby preventing the outlet air temperature from being too cold.

[0060] Optionally, the processor can min The first proportionality coefficient is determined by the size relationship of

[0061] In T out <T min In the case of, the processor determines the first proportionality coefficient to be K1. Or,

[0062] In T min <T out <T comf In this case, the processor determines the first proportional coefficient to be K2.

[0063] Among them, T out Indicates the outlet air temperature, T comf Represents the target comfort temperature value, K1≥K2>1.

[0064] Thus, in T out <T min or T min <T out <T comfWhen , it indicates that the outlet air temperature is lower than the target comfortable temperature value. At this time, the outlet air temperature needs to be increased accordingly so that the adjusted outlet air temperature approaches the target comfortable temperature value. At the same time, T out <T min Downstream air temperature and T comf The temperature deviation is higher than T min <T out <T comf Downstream air temperature and T comf Therefore, T out <T min The selected proportionality coefficient K1 is higher than T min <T out <T comf The selected proportionality coefficient K2 can be calculated based on the outlet air temperature and T comf The corresponding first proportional coefficient is adaptively selected according to the size of the temperature deviation to achieve accurate adjustment of the speed of the indoor fan.

[0065] Optionally, the processor can min The relationship between the temperature difference and the target comfortable temperature value is used to determine the absolute value of the first temperature difference, including:

[0066] In T out <T min In the case of out -T min |. Or,

[0067] In T min <T out <T comf In the case of out -T comf |.

[0068] Among them, T out Indicates the outlet air temperature, T comf Indicates the target comfort temperature value.

[0069] Thus, in T out <T min When the target speed change rate is used to adjust the speed of the indoor fan, the outlet air temperature can be quickly raised to the minimum acceptable comfortable temperature. min <T out <T comf When the air outlet temperature is too low, the air outlet temperature can be quickly raised to the target comfortable temperature value. It can effectively prevent the air outlet temperature from being too low and improve the consumer's experience comfort.

[0070] It should be noted that in T out <T minIn the case of out -T sel | is determined as the first temperature difference absolute value. T sel Represents any value within the interval. The interval range is [T min ,T comf ). In this way, the outlet air temperature can be quickly raised to T sel .

[0071] Optionally, combined Figure 4 As shown, the processor increases the speed value of the indoor fan, including:

[0072] S21, the processor based on the air outlet temperature and T max The size relationship between the two determines the second proportional coefficient and the second temperature difference absolute value, T max Indicates the maximum acceptable comfort temperature.

[0073] S22, the processor determines the target speed change rate according to the second proportional coefficient, the second temperature difference absolute value and the air outlet area.

[0074] S23: The processor increases the speed value of the indoor fan according to the target speed change rate.

[0075] Thus, the embodiment of the present disclosure is based on the outlet air temperature and T max The second proportional coefficient is determined according to the relationship between the outlet air temperature and T max The second temperature difference absolute value is determined based on the size relationship between the outlet air temperature and the maximum acceptable comfort temperature and the target comfort temperature value, and the second proportional coefficient and the outlet area to set the speed change rate, effectively reduce the outlet air temperature value, and make the adjusted outlet air temperature approach the target comfort temperature value, thereby preventing the outlet air temperature from overheating.

[0076] Optionally, the processor can max The second proportionality coefficient is determined by the size relationship of

[0077] In T comf <T out <T max In the case of, the processor determines the second proportional coefficient to be K3. Or,

[0078] In T out >T max In this case, the processor determines the second proportional coefficient to be K4.

[0079] Among them, T out Indicates the outlet air temperature, Tcomf Indicates the target comfort temperature value, K4≥K3>1.

[0080] Thus, in T comf <T out <T max or T out >T max When , it indicates that the outlet air temperature is higher than the target comfortable temperature value. At this time, the outlet air temperature needs to be lowered accordingly so that the adjusted outlet air temperature approaches the target comfortable temperature value. At the same time, T comf <T out <T max Downstream air temperature and T comf The temperature deviation is less than T out >T max Downstream air temperature and T comf Therefore, T comf <T out <T max The selected proportional coefficient K3 is less than T out >T max The selected proportionality coefficient K4 can be calculated based on the outlet air temperature and T comf The corresponding second proportional coefficient is adaptively selected according to the size of the temperature deviation to achieve precise adjustment of the speed of the indoor fan.

[0081] Optionally, the processor can max The absolute value of the second temperature difference is determined by the relationship between the magnitude of

[0082] In T comf <T out <T max or T out >T max In the case of out -T max |.

[0083] Among them, T out Indicates the outlet air temperature, T comf Indicates the target comfort temperature value.

[0084] In this way, the air outlet temperature can be quickly reduced to the target comfortable temperature value, which helps prevent the air outlet temperature from overheating and improves the consumer's experience comfort.

[0085] Optionally, the processor determines the target speed change rate, including:

[0086] The processor calculates v = K × ΔT cur / S.

[0087] Wherein, v represents the target speed change rate, and S represents the air outlet area.

[0088] K represents the first proportionality coefficient and ΔT cur represents the absolute value of the first temperature difference, or K represents the second proportionality coefficient and ΔT cur Indicates the absolute value of the second temperature difference.

[0089] In this way, when the first proportional coefficient is K1, the outlet air temperature can be quickly raised to the minimum acceptable comfortable temperature. When the first proportional coefficient is K2, the outlet air temperature can be quickly raised to the target comfortable temperature. When the first proportional coefficient is K3 or K4, the outlet air temperature can be quickly reduced to the target comfortable temperature.

[0090] Optionally, the processor reduces the speed value of the indoor fan, including:

[0091] In n cur >n min In this case, the processor reduces the speed value of the indoor fan.

[0092] The processor increases the speed value of the indoor fan, including:

[0093] In n cur <n max In this case, the processor increases the speed of the indoor fan.

[0094] Among them, n min Indicates the lower speed threshold, n max Indicates the upper speed threshold, n cur Indicates the current speed value.

[0095] Thus, in n curr >n min When n is reached, it indicates that the current speed value is higher than the lower speed threshold of the indoor fan. Then the speed value of the indoor fan still has room for downward adjustment. Therefore, the processor executes the operation of reducing the speed value of the indoor fan. cur <n max , indicating that the current speed value is lower than the upper speed threshold of the indoor fan. Then the speed value of the indoor fan still has room for upward adjustment. Therefore, the processor performs an operation to increase the speed value of the indoor fan. In this way, the disclosed embodiment can fine-tune the speed value within the safe speed adjustment range of the indoor fan, effectively preventing the outlet air temperature from being too cold or too hot, and improving the consumer's experience comfort.

[0096] In practical applications, such as Figure 1 and Figure 5 As shown, the method for controlling the air conditioner specifically performs the following steps:

[0097] S101, the processor executes an electric heating mode in response to a control instruction. The control instruction is used to instruct the execution of the electric heating mode.

[0101] S105: When the air outlet temperature is lower than the target comfort temperature value, execute S106 and S107.

[0102] S106, processor in T out <T min When the condition is established, the first proportional coefficient is determined to be K1, and the first temperature difference absolute value ΔT is determined. cur1 |T out -T min |.

[0103] S107, processor in T min <T out <T comf When the condition is established, the first proportional coefficient is determined to be K2, and the first temperature difference absolute value ΔT is determined. cur1 |T out -T comf |.
