[0028] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for preventing cold wind in an air conditioner, comprising:

[0029] S101, when the air conditioner is turned on for heating, the processor obtains the initial indoor temperature.

[0030] S102: After the air conditioner runs continuously for a target time, the processor obtains the indoor coil temperature.

[0031] S103, the processor determines and executes the target cold wind prevention plan of the air conditioner according to the indoor initial temperature and the indoor coil temperature.

[0032] Using the method for preventing cold wind in an air conditioner provided by an embodiment of the present disclosure, when the air conditioner is turned on for heating, the initial indoor temperature is first obtained to determine the actual heating demand corresponding to the indoor environment. Subsequently, after the air conditioner has been running for a target period of time, the embodiment of the present disclosure ensures that the indoor heat exchanger has obtained sufficient heat exchange, and obtains the indoor coil temperature at this time to determine the actual heating capacity of the air conditioner after running for a period of time. Then, the embodiment of the present disclosure can determine the adaptation of the actual heating demand of the indoor environment and the actual heating capacity of the air conditioner based on the initial indoor temperature and the indoor coil temperature, and select a suitable target cold wind prevention scheme accordingly so that the air conditioner is executed accordingly, thereby improving the reliability of the cold wind prevention scheme, while ensuring the user's comfortable experience, taking into account the energy-saving effect of the air conditioner.

[0033] Optionally, the target duration can be set in combination with the outdoor ambient temperature. Preferably, the target duration can be set to 15 minutes to ensure that the indoor heat exchanger has obtained sufficient heat exchange. The target duration can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 10 minutes or 20 minutes.

[0034] Optionally, the processor determines and executes the target cold wind prevention scheme of the air conditioner according to the indoor initial temperature and the indoor coil temperature, including: when the indoor initial temperature is less than the preset ambient temperature and the indoor coil temperature is less than the first coil temperature, the processor controls the compressor to shut down and the indoor fan to stop; or, when the indoor initial temperature is less than the preset ambient temperature and the indoor coil temperature is greater than or equal to the first coil temperature and less than the second coil temperature, the processor controls the electric heating to start and controls the compressor to increase the frequency until the indoor coil temperature reaches the second coil temperature; or, when the indoor initial temperature is less than the preset ambient temperature and the indoor coil temperature is greater than or equal to the second coil temperature and less than the third coil temperature, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the third coil temperature. Wherein, the first coil temperature is less than the second coil temperature, and the second coil temperature is less than the third coil temperature.

[0035] In this way, when the initial indoor temperature is lower than the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively high. If the indoor coil temperature after the air conditioner has been running for a period of time is lower than the first coil temperature, it indicates that the heating capacity of the air conditioner itself is relatively weak and it is difficult to meet the high heating demand of the indoor environment. Therefore, the disclosed embodiment controls the compressor to shut down in time and controls the internal fan to stop in time, thereby preventing the indoor coil temperature from being too low to blow out cold air, causing a poor user experience, and avoiding the air conditioner from continuing to run inefficiently, causing energy waste. While ensuring the user's comfortable experience, the energy-saving effect of the air conditioner is taken into account.

[0036] Similarly, when the initial indoor temperature is lower than the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively high. If the indoor coil temperature after the air conditioner has been running for a period of time is greater than or equal to the first coil temperature and lower than the second coil temperature, it indicates that the air conditioner has a certain heating capacity, but it takes a long time to meet the high heating demand of the indoor environment. Therefore, the disclosed embodiment controls the electric heating to turn on and controls the compressor to increase the frequency until the indoor coil temperature reaches the second coil temperature, so that the indoor coil temperature can be quickly increased to the second coil temperature by increasing the compressor frequency, and the electric heating device is turned on to speed up the heating, so as to quickly increase the air outlet temperature of the air conditioner, which is conducive to ensuring the user's comfortable experience.

[0037] Similarly, when the initial indoor temperature is lower than the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively high. If the indoor coil temperature after the air conditioner has been running for a period of time is greater than or equal to the second coil temperature and lower than the third coil temperature, it indicates that the air conditioner has a strong heating capacity and can meet the high heating demand of the indoor environment in a short time. Therefore, the embodiment of the present disclosure controls the compressor frequency increase until the indoor coil temperature reaches the third coil temperature, so that the indoor coil temperature can be quickly increased to the third coil temperature by increasing the compressor frequency to achieve a stable air outlet temperature, which is conducive to ensuring the user's comfortable experience.

[0038] Optionally, the processor controls the electric heating to turn on and controls the compressor to increase the frequency until the indoor coil temperature reaches the second coil temperature. It also includes: when the compressor is increased to the highest frequency, if the indoor coil temperature does not reach the second coil temperature, the processor controls the indoor fan to reduce the speed.

[0039] In this way, in order to quickly increase the indoor coil temperature to the second coil temperature, the embodiment of the present disclosure preferentially adopts the method of increasing the compressor frequency, accompanied by electric heating to assist heating. If the indoor coil temperature reaches the second coil temperature, the embodiment of the present disclosure controls the compressor to stop the frequency increase operation. However, if the compressor frequency is already the highest heating frequency, and the indoor coil temperature has not yet reached the second coil temperature, the embodiment of the present disclosure further controls the internal fan to reduce the speed, thereby increasing the indoor coil temperature by reducing the speed of the internal fan, and then quickly increasing the air outlet temperature of the air conditioner, which is conducive to ensuring the user's comfortable experience.

[0040] Optionally, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the third coil temperature, and also includes: when the compressor is increased to the highest frequency, if the indoor coil temperature does not reach the third coil temperature, the processor controls the electric heating to turn on.

[0041] In this way, in order to quickly increase the indoor coil temperature to the third coil temperature, the embodiment of the present disclosure preferentially adopts the method of increasing the compressor frequency. If the indoor coil temperature reaches the third coil temperature, the embodiment of the present disclosure controls the compressor to stop the frequency increase operation. However, if the compressor frequency is already the highest heating frequency, and the indoor coil temperature has not yet reached the third coil temperature, the embodiment of the present disclosure further turns on electric heating to assist in heating, thereby taking into account the relatively high heating demand of the indoor environment at this time, and can use the electric heating method with higher heating efficiency to quickly increase the air outlet temperature of the air conditioner, which is conducive to better ensuring the user's comfortable experience.

[0042] Optionally, the processor determines and executes the target cold wind prevention scheme of the air conditioner according to the indoor initial temperature and the indoor coil temperature, including: when the indoor initial temperature is greater than or equal to the preset ambient temperature and the indoor coil temperature is less than the fourth coil temperature, the processor controls the compressor to shut down and the indoor fan to stop; or, when the indoor initial temperature is greater than or equal to the preset ambient temperature and the indoor coil temperature is greater than or equal to the fourth coil temperature and less than the fifth coil temperature, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the fifth coil temperature; or, when the indoor initial temperature is greater than or equal to the preset ambient temperature and the indoor coil temperature is greater than or equal to the fifth coil temperature and less than the sixth coil temperature, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the sixth coil temperature. Wherein, the fourth coil temperature is less than the fifth coil temperature, and the fifth coil temperature is less than the sixth coil temperature.

[0043] In this way, when the initial indoor temperature is greater than or equal to the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively low. If the indoor coil temperature is less than the fourth coil temperature after the air conditioner has been running for a period of time, it indicates that the heating capacity of the air conditioner itself is relatively weak and it is difficult to meet the heating demand of the indoor environment at this time. Therefore, the disclosed embodiment controls the compressor to shut down in time and controls the internal fan to stop in time, so as to prevent the indoor coil temperature from being too low to blow out cold air, causing a poor user experience, and to avoid the air conditioner from continuing to run inefficiently and causing energy waste. While ensuring the user's comfortable experience, the energy-saving effect of the air conditioner is taken into account.

[0044] Similarly, when the initial indoor temperature is greater than or equal to the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively low. If the indoor coil temperature after the air conditioner has been running for a period of time is greater than or equal to the fourth coil temperature and less than the fifth coil temperature, it indicates that the air conditioner has a certain heating capacity and still needs some time to meet the heating demand of the indoor environment at this time. Therefore, the embodiment of the present disclosure controls the compressor frequency increase until the indoor coil temperature reaches the fifth coil temperature, so that the indoor coil temperature can be quickly increased to the fifth coil temperature by increasing the compressor frequency, so as to stably increase the air outlet temperature of the air conditioner, which is conducive to ensuring the user's comfortable experience.

[0045] Similarly, when the initial indoor temperature is greater than or equal to the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively low. If the indoor coil temperature after the air conditioner has been running for a period of time is greater than or equal to the fifth coil temperature and less than the sixth coil temperature, it indicates that the air conditioner has a strong heating capacity and can meet the low heating demand of the indoor environment in a short time. Therefore, the embodiment of the present disclosure controls the compressor frequency increase until the indoor coil temperature reaches the sixth coil temperature, so that the indoor coil temperature can be quickly increased to the sixth coil temperature by increasing the compressor frequency to achieve a stable air outlet temperature, which is conducive to ensuring the user's comfortable experience.

[0046] Optionally, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the fifth coil temperature, and also includes: when the compressor is increased to the highest frequency, if the indoor coil temperature does not reach the fifth coil temperature, the processor controls the electric heating to be turned on intermittently.

[0047] In this way, in order to quickly increase the indoor coil temperature to the fifth coil temperature, the embodiment of the present disclosure preferentially adopts the method of increasing the compressor frequency. If the indoor coil temperature reaches the fifth coil temperature, the embodiment of the present disclosure controls the compressor to stop the frequency increase operation. However, if the compressor frequency is already the highest heating frequency, and the indoor coil temperature has not yet reached the fifth coil temperature, the embodiment of the present disclosure further controls the intermittent opening of the electric heating. On the one hand, by turning on the electric heating to assist in heating, the air outlet temperature of the air conditioner can be quickly increased, which is conducive to ensuring the user's comfortable experience. On the other hand, considering that the actual heating demand of the indoor environment is relatively low, in order to avoid the overflow of the actual heating capacity of the air conditioner caused by the continuous opening of the electric heating, the embodiment of the present disclosure adopts the intermittent opening of the electric heating, which can effectively reduce energy waste and help improve the energy-saving effect of the air conditioner. In addition, when executing the anti-cold wind scheme under the above working conditions, in order to prevent the electric heating device from fusing due to slow heat dissipation, the embodiment of the present disclosure no longer performs the internal fan speed reduction operation, which further improves the safety of the anti-cold wind scheme.

[0048] Optionally, the processor controls the compressor to increase the frequency until the indoor coil temperature reaches the sixth coil temperature, and also includes: when the compressor frequency is increased to the highest frequency, if the indoor coil temperature does not reach the sixth coil temperature, the processor controls the indoor fan to reduce the speed.

[0049] In this way, in order to quickly increase the indoor coil temperature to the sixth coil temperature, the embodiment of the present disclosure preferentially adopts the method of increasing the compressor frequency. If the indoor coil temperature reaches the sixth coil temperature, the embodiment of the present disclosure controls the compressor to stop the frequency increase operation. However, if the compressor frequency is already the highest heating frequency, and the indoor coil temperature has not yet reached the sixth coil temperature, the embodiment of the present disclosure further controls the internal fan to reduce the speed, thereby increasing the indoor coil temperature by reducing the speed of the internal fan to achieve a stable air outlet temperature, which is conducive to ensuring the user's comfortable experience. In addition, on the one hand, considering that the actual heating demand of the indoor environment is relatively low, in order to avoid turning on the electric heating and causing the actual heating capacity of the air conditioner to overflow, the embodiment of the present disclosure adopts the method of reducing the speed of the internal fan, which can effectively reduce energy waste and help improve the energy-saving effect of the air conditioner. On the other hand, when the anti-cold wind scheme is executed under the above working conditions, the embodiment of the present disclosure no longer performs the electric heating start operation, thereby preventing the electric heating device from fusing due to slow heat dissipation, further improving the safety of the anti-cold wind scheme.

[0057] S207, when the compressor frequency is increased to the highest frequency, if the indoor coil temperature does not reach the third coil temperature, the processor controls the electric heating to turn on.

[0058] The first coil temperature is lower than the second coil temperature, and the second coil temperature is lower than the third coil temperature.

[0059] Using the method for preventing cold wind from an air conditioner provided by the embodiment of the present disclosure, when the initial indoor temperature is lower than the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively high. The embodiment of the present disclosure then obtains the indoor coil temperature after the air conditioner has been running for a period of time to determine the actual heating capacity of the air conditioner at this time. When the heating capacity of the air conditioner fails to meet the high heating demand of the indoor environment, the embodiment of the present disclosure can select a suitable target cold wind prevention scheme so that the air conditioner is executed accordingly, thereby improving the reliability of the cold wind prevention scheme, while ensuring the user's comfortable experience, taking into account the energy-saving effect of the air conditioner.

[0060] Optionally, the preset ambient temperature can be set in combination with the size of the indoor space.

[0069] Optionally, the preset gear is at most two gears lower than the initial gear to achieve a smooth reduction in the speed of the internal fan. The preset gear can also be adjusted according to actual user needs, and can also be set to any other reasonable gear such as medium wind gear or low wind gear.

[0070] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for preventing cold wind in an air conditioner, comprising:

[0079] Using the method for preventing cold wind from an air conditioner provided by the embodiment of the present disclosure, when the initial indoor temperature is greater than or equal to the preset ambient temperature, it indicates that the actual heating demand corresponding to the indoor environment is relatively low. The embodiment of the present disclosure then obtains the indoor coil temperature after the air conditioner has been running for a period of time to determine the actual heating capacity of the air conditioner at this time. When the heating capacity of the air conditioner fails to meet the low heating demand of the indoor environment, the embodiment of the present disclosure can select a suitable target cold wind prevention scheme so that the air conditioner is executed accordingly, thereby improving the reliability of the cold wind prevention scheme, while ensuring the user's comfortable experience, taking into account the energy-saving effect of the air conditioner.

[0080] Optionally, the preset ambient temperature can be set in combination with the size of the indoor space. Preferably, the preset ambient temperature can be set to 10°C to determine whether the heating demand of the indoor environment is high.

The fourth coil temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 20°C or 22°C.

[0082] Optionally, the fifth coil temperature can be set in combination with the heating target temperature. Preferably, the fifth coil temperature can be set to 27°C so that the air outlet temperature of the air conditioner is just close to the heating target temperature set by the user.

[0084] Optionally, the processor controls the compressor to increase frequency, including: the processor controls the compressor to increase frequency at a preset rate.

[0085] In this way, in order to effectively increase the indoor coil temperature, the embodiment of the present disclosure can gradually increase the frequency of the compressor at a preset rate to steadily increase the air outlet temperature of the air conditioner, thereby helping to ensure a comfortable experience for the user.

[0086] Optionally, the preset rate can be set to 4 Hz / 3 min to achieve a gradual increase in the compressor frequency. The preset rate can also be adjusted according to the actual needs of the user, and can also be set to 5 Hz / 3 min or 3 Hz / 3 min or any other reasonable value.

[0094] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for preventing cold wind in an air conditioner, comprising:

[0095] S401, when the air conditioner is turned on for heating, the processor obtains the initial indoor temperature.

[0096] S402: After the air conditioner runs continuously for a target time, the processor obtains the indoor coil temperature.

[0097] S403, the processor determines and executes the target cold wind prevention plan of the air conditioner according to the indoor initial temperature and the indoor coil temperature. Or,

[0098] S404, when the indoor coil temperature is greater than or equal to the seventh coil temperature, the processor controls the compressor to operate at a set frequency and controls the indoor fan to operate at a set speed.

[0099] According to the method for preventing cold wind of air conditioner provided by the embodiment of the present disclosure, when the air conditioner is turned on for heating, the indoor initial temperature is first obtained to judge the actual heating demand corresponding to the indoor environment. Then, after the air conditioner continues to run for the target time, the embodiment of the present disclosure ensures that the indoor heat exchanger has obtained sufficient heat exchange, and obtains the indoor coil temperature at this time to determine the actual heating capacity of the air conditioner after running for a period of time. Then, the embodiment of the present disclosure can determine the adaptation of the actual heating demand of the indoor environment and the actual heating capacity of the air conditioner according to the indoor initial temperature and the indoor coil temperature. When the indoor coil temperature is greater than or equal to the seventh coil temperature, it indicates that the heating capacity of the air conditioner at this time has met the heating demand corresponding to the indoor environment. Therefore, the embodiment of the present disclosure can control the compressor to run at a set frequency and control the indoor fan to run at a set speed, so that the air conditioner can be operated in a timely manner according to the normal heating mode, thereby ensuring the user's subsequent comfortable experience. In the case where the two are not compatible, the embodiment of the present disclosure selects a suitable target cold wind prevention scheme based on this so that the air conditioner is executed accordingly, thereby improving the reliability of the cold wind prevention scheme, while ensuring the user's comfortable experience, taking into account the energy-saving effect of the air conditioner.

[0100] Optionally, the seventh coil temperature can be set in combination with the user's body temperature. Preferably, the seventh coil temperature can be set to 35°C to determine whether the current heating capacity of the air conditioner is extremely strong. The seventh coil temperature can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 34°C or 36°C.
