[0037] In order to enable a person skilled in the art to more fully understand the features and technical contents of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0038] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0039] Unless otherwise specified, the term "a plurality of" means two or more.

[0040] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

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

[0042] The term "corresponding" can refer to a kind of association or binding relationship, A corresponding to B means that there is a kind of association or binding relationship between A and B.

[0043] When the air conditioner configured with the electric heating function is started to operate in the electric heating mode, the gear of the indoor fan has multiple fixed gears, for example, a high wind gear, a medium wind gear and a low wind gear. The fan rotating speed corresponding to the high wind gear, the medium wind gear and the low wind gear decreases in turn. Generally, the high wind gear is used to meet the rated capacity requirement of the air conditioner, and the low wind gear is used to meet the condensation requirement of the air conditioner. When the air conditioner has the electric heating and refrigeration demand, the air conditioner will be pre-configured with a set gear, and the indoor fan will be controlled to start operating at the set gear. In this way, when the environmental temperature value is low or high, the temperature value at the outlet of the indoor unit is prone to be too cold or too hot, affecting the experience comfort of the consumer.

[0044] The related art discloses the following technical solution: when the air conditioner operates in the electric heating mode, the outlet temperature value is obtained; in the case that the outlet temperature value is less than the lower temperature threshold, the indoor fan is controlled to operate at the high wind gear. In the case that the outlet temperature value is greater than the upper temperature threshold, the indoor fan is controlled to operate at the low wind gear.

[0045] However, when the air conditioner operates in the electric heating mode, the indoor fan operates at the high wind gear when the environmental temperature value is low, resulting in a low outlet temperature. When the environmental temperature value is high, the indoor fan operates at the low wind gear, resulting in a high outlet temperature. In this way, the technical solution adopted by the related art cannot effectively overcome the problem of too cold or too hot outlet temperature, and the improvement of the experience comfort of the consumer is not significant.

[0046] In combination Figure 1 As shown in the figure, 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 operates in the refrigeration mode, refrigeration is performed through the refrigerant circulation system. When the air conditioner operates in the electric heating mode, heating is performed through the electric heating device 10, 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 operates. At this time, the electric heating device 10 is the only heat source for heating operation. In addition, the characteristic of the 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 the air volume.

[0047] According to the heat calculation formula: Q = c x m x ΔT. Wherein, 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] In the case that the electric heating power of the electric heating device 10 of the air conditioner is a constant value, that is, Q is a constant value. In the case of normal atmospheric pressure, the air specific heat capacity changes very little when the air conditioner operates in the heating mode, and the air specific heat capacity is approximately a constant value. When the rotation speed of the indoor fan of the air conditioner changes, the air volume will change, and ΔT will also change accordingly. Thus, in the case that the changes of Q and c are very small, m is inversely proportional to ΔT. Thus, when the air conditioner operates in the heating mode, if the outlet air temperature is too high, the outlet air temperature can be reduced by increasing the circulating air volume. When the air conditioner operates in the 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 structure of the air conditioner described above, in combination with Figure 2 the air conditioner, the embodiment of the disclosure provides a method for controlling the air conditioner, comprising the steps of:

[0050] S01, in the case that the air conditioner operates in the electric heating heating mode, the processor acquires the outlet air temperature of the indoor unit. Wherein the electric heating power of the electric heating device is a constant value.

[0051] S02, in the case that the outlet air temperature is less than the target comfort temperature value, the processor reduces the rotation speed value of the indoor fan to increase the outlet air temperature. Or,

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

[0053] By adopting the method for controlling the air conditioner provided by the embodiment of the disclosure, when the outlet air temperature is less than the target comfort temperature value, it indicates that the outlet air temperature is too low. Since the circulating air volume and the size of the outlet air temperature are inversely proportional in the electric heating heating mode. Therefore, the embodiment of the disclosure can achieve the purpose of increasing the outlet air temperature by reducing the rotation speed value of the indoor fan, so as 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 disclosure can achieve the purpose of reducing the outlet air temperature by increasing the rotation speed value of the indoor fan, so as to prevent the outlet air temperature from being too hot. In summary, the embodiment of the disclosure can adaptively adjust the rotation 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 tends to the target comfort temperature value, prevents the outlet air temperature from being too cold or too hot, and improves the experience comfort of consumers.

[0054] Optionally, in combination with Figure 3 the air conditioner, the processor reduces the rotation speed value of the indoor fan, comprising:

[0055] S11, the processor determines a first proportional coefficient according to the size relationship between the outlet air temperature and T min . minRepresents the minimum acceptable comfortable temperature.

[0056] S12, the processor determines the absolute value of the first temperature difference according to the relationship between the outlet air temperature and T min and the target comfortable temperature value.

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

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

[0059] In this way, the embodiment of the present disclosure determines the first proportionality coefficient according to the relationship between the outlet air temperature and T min Then, according to the relationship between the outlet air temperature and T min and the target comfortable temperature value, determine the absolute value of the first temperature difference to obtain the temperature difference corresponding to the outlet air temperature. Finally, determine the target rotational speed change rate according to the first proportionality coefficient, the absolute value of the first temperature difference, and the outlet area, and reduce the rotational speed value of the indoor fan according to the target rotational speed change rate. In this way, the embodiment of the present disclosure can set the rotational speed change rate according to the relationship between the outlet air temperature and the minimum acceptable comfortable temperature and the target comfortable temperature value, the first proportionality coefficient, and the outlet area, effectively increase the outlet air temperature value, and make the adjusted outlet air temperature approach the target comfortable temperature value, preventing the outlet air temperature from being too cold.

[0060] Optionally, the processor determines the first proportionality coefficient according to the relationship between the outlet air temperature and T min , including:

[0061] When T out < T min , the processor determines that the first proportionality coefficient is K1. Or,

[0062] When T min < T out < T comf , the processor determines that the first proportionality coefficient is K2.

[0063] Among them, T out represents the outlet air temperature, T comf represents the target comfortable temperature value, and K1 ≥ K2 > 1.

[0064] In this way, when T out < T min or T min < T out < T comfWhen the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T out <T min When the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T comf When the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T min <T out <T comf When the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T comf When the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T out <T min When the outdoor temperature is lower than the target comfort temperature value, the outflow temperature is lower than the target comfort temperature value. At this time, the outflow temperature needs to be raised to make the adjusted outflow temperature approach the target comfort temperature value. Meanwhile, T min <T out <T comf The selected proportional coefficient K2 can be adaptively selected according to the size of the temperature deviation between the outflow temperature and T comf , and the corresponding first proportional coefficient is selected to realize accurate adjustment of the speed of the indoor fan.

[0065] Optionally, the processor determines the first temperature difference absolute value according to the size relationship between the outflow temperature and T min and the target comfort temperature value, and the determination includes:

[0066] When T out <T min , the processor determines the first temperature difference absolute value as |T out -T min |. Alternatively,

[0067] When T min <T out <T comf , the processor determines the first temperature difference absolute value as |T out -T comf |.

[0068] Wherein, T out represents the outflow temperature, and T comf represents the target comfort temperature value.

[0069] In this way, when T out <T min , the speed of the indoor fan is adjusted by the target speed change rate, so that the outflow temperature can be quickly raised to the acceptable comfort temperature minimum value. And when T min <T out <T comf , the outflow temperature can be quickly raised to the target comfort temperature value. It can effectively prevent the outflow temperature from being too cold and improve the experience comfort of consumers.

[0070] It should be noted that when T out <T minIn the case that T out -T sel | is determined as the first temperature difference absolute value. T sel represents an arbitrary value within the interval range. The interval range is [T min , T comf ]. In this way, the outlet air temperature can be quickly increased to T sel .

[0071] Optionally, as shown in FIG. 6, the processor increases the rotation speed value of the indoor fan, including: Figure 4

[0072] S21, the processor determines a second proportional coefficient and a second temperature difference absolute value according to the size relationship between the outlet air temperature and T max , wherein T max represents the maximum value of the acceptable comfortable temperature.

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

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

[0075] In this way, the embodiment of the disclosure determines the second proportional coefficient according to the size relationship between the outlet air temperature and T max , and determines the second temperature difference absolute value according to the size relationship between the outlet air temperature and T max , so as to obtain the temperature difference corresponding to the outlet air temperature. Finally, the target rotation speed change rate is determined according to the second proportional coefficient, the second temperature difference absolute value, and the outlet area. In this way, the embodiment of the disclosure can set the rotation speed change rate according to the size relationship between the outlet air temperature and the maximum value of the acceptable comfortable temperature and the target comfortable temperature value, and the second proportional coefficient and the outlet area, effectively reduce the outlet air temperature value, and make the adjusted outlet air temperature tend to the target comfortable temperature value, preventing the outlet air temperature from being too high.

[0076] Optionally, the processor determines the second proportional coefficient according to the size relationship between the outlet air temperature and T max , including:

[0077] In the case that T comf <T out <T max , the processor determines the second proportional coefficient as K3. Alternatively,

[0078] In the case that T out >T max , the processor determines the second proportional coefficient as K4.

[0079] wherein T out represents the outlet air temperature, and T​comf represents a target comfortable temperature value, K4>K3>1.

[0080] In this way, when T comf <T out <T max or T out >T max , it indicates that the air outlet temperature is higher than the target comfortable temperature value. At this time, the air outlet temperature needs to be correspondingly reduced to make the adjusted air outlet temperature approach the target comfortable temperature value. At the same time, T comf <T out <T max The temperature deviation of the air outlet temperature below T comf is less than T out >T max The temperature deviation of the air outlet temperature below T comf . To this end, T comf <T out <T max The selected proportional coefficient K3 is less than T out >T max The selected proportional coefficient K4 can adaptively select the corresponding second proportional coefficient according to the size of the temperature deviation of the air outlet temperature from T comf , so as to realize accurate adjustment of the speed of the indoor fan.

[0081] Optionally, the processor determines a second temperature difference absolute value according to the size relationship between the air outlet temperature and T max , including:

[0082] In the case of T comf <T out <T max or T out >T max , the processor determines that the second temperature difference absolute value is |T out -T max |.

[0083] Wherein, T out represents the air outlet temperature, and T comf represents the target comfortable temperature value.

[0084] In this way, the air outlet temperature can be quickly reduced to the target comfortable temperature value, which is beneficial to prevent the air outlet temperature from being too hot and improve the experience comfort of consumers.

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

[0086] The processor calculates v=KxΔT 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 K represents the absolute value of the first temperature difference, or K represents the second proportionality coefficient and ΔT cur This represents the absolute value of the second temperature difference.

[0089] Thus, when the first proportionality coefficient is K1, the outlet air temperature can be quickly raised to the minimum acceptable comfort temperature. When the first proportionality coefficient is K2, the outlet air temperature can be quickly raised to the target comfort temperature value. When the first proportionality coefficient is K3 or K4, the outlet air temperature can be quickly lowered to the target comfort temperature value.

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

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

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

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

[0094] Where, n min Indicates the lower limit threshold of rotational speed, n max n represents the upper limit threshold of rotational speed. cur This indicates the current rotational speed.

[0095] Thus, in n curr >n min When the current speed value is higher than the lower limit threshold of the indoor fan speed, it indicates that the indoor fan speed value still has room for reduction. Therefore, the processor executes the operation to reduce the indoor fan speed value. In n cur <n max When the current speed value is lower than the upper limit threshold of the indoor fan speed, it indicates that the indoor fan speed value still has room for adjustment. Therefore, the processor executes the operation of increasing the indoor fan speed value. In this way, the embodiments of this disclosure can fine-tune the speed value of the indoor fan within the safe speed adjustment range, effectively preventing the outlet air temperature from being too cold or too hot, and improving the comfort of the consumer experience.

[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 responds to the control instruction and executes the electric heating mode. The control instruction is used to instruct the execution of the electric heating mode.

[0098] S102, the processor controls the electric heating device to be turned on and controls the indoor fan to be started.

[0099] S103, the processor determines whether the air conditioner satisfies a termination heating condition. If not, S104 is executed, and if yes, S116 is executed.

[0100] S104, the processor acquires the outlet air temperature of the indoor unit, and executes S105 or S110.

[0101] S105, in the case where the outlet air temperature is less than a target comfort temperature value, S106 and S107 are executed.

[0102] S106, the processor determines whether T out <T min is true, determines the first proportional coefficient K1, and determines the first temperature difference absolute value ΔT cur1 as |T out -T min |.

[0103] S107, the processor determines whether T min <T out <T comf is true, determines the first proportional coefficient K2, and determines the first temperature difference absolute value ΔT cur1 as |T out -T comf |.

[0104] S108, the processor calculates v1=K×ΔT cur1 / S. K represents the first proportional coefficient.

[0105] S109, the processor determines whether n cur >n min is true. If yes, the current rotating speed value is reduced by v1, the outlet air temperature is increased, and the adjusted outlet air temperature tends to the target comfort temperature value.

[0106] S110, in the case where the outlet air temperature is greater than the target comfort temperature value, S111 and S112 are executed.

[0107] S111, the processor determines whether T comf <T out <T max is true.

[0108] S112, the processor determines whether T out >T max is true.

[0109] S113, the processor determines the second temperature difference absolute value ΔTcur2 |T out -T max |。

[0110] S114, the processor calculates v2 = K x AT cur2 / S. K represents a second proportional coefficient.

[0111] S115, the processor increases the current speed value by v2 when n cur <n max is true, to reduce the outlet air temperature and make the adjusted outlet air temperature approach the target comfortable temperature value.

[0112] S116, the processor exits the electric heating mode.

[0113] In combination with Figure 6 As shown in the figure, the embodiment of the present disclosure provides a device 300 for controlling an air conditioner, which comprises a processor 400 and a memory 401. Optionally, the device can also comprise a communication interface 402 and a bus 403.
