When the air conditioner is in heating operation, when one of the conditions of refrigerant leakage in the air conditioner system, unsmooth ventilation around the outdoor unit, icing of the heat exchanger of the outdoor unit or excessively low outdoor environment temperature occurs, the heating capacity of the air conditioner is attenuated, the temperature of the coil pipe of the indoor unit is reduced, when the temperature of the coil pipe of the indoor unit is reduced to a certain degree, in order to prevent uncomfortable feeling of a user caused by lower air temperature of air outlet of the air conditioner, the operation of the fan of the indoor unit is required to be stopped in a staged manner, and the fan is started again to operate after the temperature of the coil pipe of the indoor unit is increased, so that the air outlet temperature of the air conditioner is comfortable, and cold air is prevented from being blown out.
When the temperature of the indoor unit coil is too low, the air conditioner stops the fan operation until the temperature of the indoor unit coil is increased to a proper temperature, and the function of continuing the fan operation is generally called a cold air prevention function of the air conditioner.
In the prior art, the air conditioner generally has a cold air prevention function, and cold air can be prevented from being blown out in the heating process of the air conditioner. However, the duration of the cold air prevention function is generally longer, and the waiting time of a user is longer, so that the air conditioner heating operation is better carried out, and the application provides a control method for cold air prevention of an air conditioner.
The control method for preventing cold air of the air conditioner is applied to the air conditioner with the heat storage device arranged in the indoor unit. Here, the heat storage device has at least a function of releasing heat in the air conditioner to raise the temperature of the indoor unit coil. The installation position of the heat storage device is not particularly limited.
As shown in fig. 1, an embodiment of the present disclosure provides a control method for preventing cold air of an air conditioner, the control method including:
and S01, under the condition that the air conditioner determines that the cold air prevention function is started, controlling the heat storage device to release heat so as to raise the temperature of the indoor unit coil.
Here, the cold air prevention function may be started under a condition that the current indoor unit coil temperature is less than the cold air prevention temperature point. The current indoor unit coil temperature is smaller than the cold air prevention temperature point, which means that cold air is blown out if the air conditioner indoor unit fan continues to operate at the current indoor unit coil temperature. Therefore, under the condition that the temperature of the coil pipe of the current indoor unit is smaller than the cold air prevention temperature point, the air conditioner starts the cold air prevention function. In this embodiment, the cold air prevention temperature point may be 25 ℃, and may be set before the air conditioner leaves the factory.
Step S02, the air conditioner obtains the first coil temperature of the indoor unit coil, and controls the air conditioner to operate in a wind speed mode corresponding to the first coil temperature.
In this embodiment, the air conditioner is preset with an association relationship between the indoor unit coil temperature and the wind speed mode, where the association relationship includes a one-to-one correspondence between the indoor unit coil temperature interval and the wind speed mode, and the wind speed mode corresponding to the indoor unit coil temperature interval where the first coil temperature is located can be obtained by searching the association relationship, so as to control the air conditioner to operate in the wind speed mode.
Optionally, the air conditioner controls the air conditioner to operate in a wind speed mode corresponding to the temperature of the first coil, including: the air conditioner obtains wind speed modes corresponding to a plurality of temperature intervals respectively; the air conditioner determines a current temperature interval in which the temperature of the first coil pipe is located, and controls the air conditioner to operate in a wind speed mode corresponding to the current temperature interval. Therefore, the indoor unit fan controls the running speed according to the wind speed mode corresponding to the current indoor unit coil temperature, so that the indoor unit heat exchange can be accelerated, and the indoor unit coil temperature can be quickly improved.
In some embodiments, the indoor unit coil temperature is divided into three temperature intervals, namely a first interval (T1, T2), a second interval (T2, T3) and a third interval (T3, T4), wherein T1< T2< T3< T4, the corresponding wind speed mode is a breeze mode, a low wind mode and a user setting mode in sequence, the wind speed of the breeze mode is lower than that of the low wind mode, and the wind speed of the low wind mode is lower than that of the user setting mode.
Optionally, after the first coil temperature reaches the first set threshold, the control method further includes: the air conditioner obtains a current wind speed mode of operation of the air conditioner and the operation time length under the current wind speed mode; if the current wind speed mode is the highest-level wind speed mode and the operation time length reaches the preset time length, the wind speed mode corresponding to the temperature of the first coil is controlled to operate.
Here, the reaching of the preset duration is used for expressing the condition that the air-out of the air conditioner is stable, that is, if the running duration reaches the preset duration, the air-out of the air conditioner is stable.
Therefore, after the running time of the air conditioner reaches the preset time, the air speed is adjusted according to the current temperature of the coil pipe of the indoor unit, so that the air outlet of the air conditioner is more stable.
Optionally, the control method further includes: if the current wind speed mode is not the highest-level wind speed mode, after the operation time length reaches the preset time length, the air conditioner is controlled to operate in a next-level wind speed mode corresponding to the current wind speed mode, and the wind speed of the next-level wind speed mode is larger than that of the current wind speed mode.
Here, the preset duration is used for expressing the condition that the temperature of the indoor unit coil rises to the lowest temperature of the temperature interval corresponding to the next stage wind speed mode, that is, if the running duration of the air conditioner reaches the preset duration, the air conditioner can run the next stage wind speed mode corresponding to the current wind speed mode.
Therefore, the fan of the indoor unit controls the running speed according to the wind speed mode, so that the heat exchange of the indoor unit can be accelerated, and the temperature of a coil pipe of the indoor unit can be quickly increased.
In some embodiments, the indoor unit coil temperature is divided into three temperature intervals, namely a first interval (T1, T2), a second interval (T2, T3) and a third interval (T3, T4), wherein T1< T2< T3< T4, the corresponding wind speed modes are a breeze mode, a low wind mode and a set mode in sequence, the wind speed of the breeze mode is lower than that of the low wind mode, the wind speed of the low wind mode is lower than that of the set mode, the preset duration is 4 minutes.
And S03, the air conditioner continuously acquires the second coil temperature of the coil of the indoor unit, and controls the heat storage device to stop releasing heat when the second coil temperature reaches a second set threshold value.
In an embodiment of the present disclosure, the second set threshold is greater than the first set threshold. If the temperature of the coil pipe of the indoor unit reaches the second set threshold value, the temperature of the coil pipe of the indoor unit is recovered to a normal value, and the heat storage device does not need to continuously release heat.
By adopting the control method for preventing cold air of the air conditioner, which is provided by the embodiment of the disclosure, under the condition that the cold air prevention function of the air conditioner is determined to be started, the heat storage device is controlled to release heat so as to raise the temperature of the indoor unit coil; acquiring a first coil temperature of the indoor unit coil, and controlling the air conditioner to run in a wind speed mode corresponding to the first coil temperature; and continuously acquiring the second coil temperature of the indoor unit coil, and controlling the heat storage device to stop releasing heat when the second coil temperature reaches a second set threshold, namely controlling the heat storage device to continuously release heat when the second coil temperature is greater than or equal to the first set threshold and less than the second set threshold. The heat storage device is controlled to release heat, so that the indoor coil pipe can be heated up quickly after the cold air prevention function is started, the cold air prevention time is shortened, and a user can feel hot air blown out by the air conditioner quickly after heating and starting.

and S11, controlling the heat storage device to store heat under the condition that the air conditioner determines that the fan of the indoor unit rotates.
Here, the heat stored in the heat storage device may be released when the cold air prevention function is turned on to raise the temperature of the indoor unit coil.
And step S12, under the condition that the air conditioner determines that the cold air prevention function is started, controlling the heat storage device to release heat so as to raise the temperature of the indoor unit coil.
And S13, the air conditioner acquires the first coil temperature of the indoor unit coil and controls the air conditioner to operate in a wind speed mode corresponding to the first coil temperature.

And S15, the air conditioner continuously acquires the second coil temperature of the coil of the indoor unit, and controls the heat storage device to stop releasing heat when the second coil temperature reaches a second set threshold value.
In an embodiment of the present disclosure, the second set threshold is greater than the first set threshold.
Optionally, the air conditioner controls the heat storage device to store heat, including: the air conditioner controls the heat storage device to store heat converted from kinetic energy generated by rotation of the indoor unit fan. Therefore, the kinetic energy generated by the rotation of the fan is effectively utilized, an electric heating device is not required to be additionally arranged, and the energy-saving and environment-friendly effects are achieved.
By adopting the control method for preventing cold air of the air conditioner, which is provided by the embodiment of the disclosure, the heat storage device stores heat when the air conditioner is in normal operation, and the stored heat is used for improving the temperature of the coil pipe of the indoor unit in the cold air preventing process; after the cold air prevention function is started, the heat storage device releases heat so as to raise the temperature of the coil pipe of the indoor unit; in the running process of the cold air prevention function, the air conditioner controls the heat storage device to store heat under the condition that the temperature of the coil pipe of the current indoor unit reaches a first set threshold value; if the new indoor unit coil temperature reaches the second set threshold, the thermal storage device stops releasing heat. The heat storage device is controlled to release heat, so that the indoor coil pipe can be heated up quickly after the cold air prevention function is started, the cold air prevention time is shortened, and a user can feel hot air blown out by the air conditioner quickly after heating and starting.
