When the air conditioner is in heating operation, when one of the conditions of refrigerant leakage in an air conditioning system, unsmooth ventilation around an outdoor unit, freezing of a heat exchanger of the outdoor unit, low outdoor environment temperature and the like occurs, the heating capacity of the air conditioner is reduced, the temperature of an indoor unit coil is reduced, when the temperature of the indoor unit coil is reduced to a certain degree, the operation of a fan of the indoor unit needs to be stopped in stages in order to prevent the air temperature of the air outlet of the air conditioner from being low and causing discomfort to users, and the fan is started to operate again after the temperature of the indoor unit coil is increased, so that the air temperature of the air outlet of the air conditioner is comfortable, and cold air is prevented from being blown out.
The function of stopping the fan of the air conditioner when the temperature of the coil pipe of the indoor unit is too low and continuing the operation of the fan until the temperature of the coil pipe of the indoor unit is raised to a proper temperature is generally called as 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 blown out in the heating process of the air conditioner can be avoided. However, the duration time of the cold air prevention function is generally longer, the waiting time of a user is longer, and in order to solve the problem and better perform air conditioning hot work, the application provides a control method for preventing cold air of an air conditioner.
The control method for preventing cold air of the air conditioner, provided by the embodiment of the disclosure, is applied to the air conditioner with the indoor unit provided with the heat storage device. Here, the heat storage device has at least a function of releasing heat to raise the temperature of the coil of the indoor unit in the air conditioner. The position where the thermal storage device is disposed may not be particularly limited.
As shown in fig. 1, an embodiment of the present disclosure provides a control method for preventing cold wind of an air conditioner, including:
and step S01, controlling the heat storage device to release heat to raise the temperature of the coil pipe of the indoor unit under the condition that the air conditioner determines that the air conditioner starts the cold air prevention function.
Here, the starting condition of the cold wind prevention function may be that the current indoor unit coil temperature is less than the cold wind prevention temperature point. When the current temperature of the coil pipe of the indoor unit is lower than the cold air prevention temperature point, the cold air is blown out if the fan of the indoor unit of the air conditioner continues to operate under the current temperature of the coil pipe of the indoor unit. Therefore, the air conditioner starts the cold air prevention function under the condition that the temperature of the coil pipe of the current indoor unit is lower than the cold air prevention temperature point. In this embodiment, the cold-proof temperature point may be 25 ℃, and may be set before the air conditioner leaves the factory.
And step S02, the air conditioner acquires the first coil temperature of the coil of the indoor unit and controls the air conditioner to operate in a wind speed mode corresponding to the first coil temperature.
In this embodiment, the air conditioner presets an association relationship between the temperature of the coil of the indoor unit and the wind speed mode, where the association relationship includes a one-to-one correspondence relationship between a temperature interval of the coil of the indoor unit and the wind speed mode, and the wind speed mode corresponding to the temperature interval of the coil of the indoor unit 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, and the air conditioner includes: the air conditioner obtains wind speed modes corresponding to a plurality of temperature intervals; the air conditioner determines a current temperature interval where 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 running speed of the fan of the indoor unit is controlled according to the wind speed mode corresponding to the current temperature of the coil pipe of the indoor unit, the heat exchange of the indoor unit can be accelerated, and the temperature of the coil pipe of the indoor unit can be quickly improved.
In some embodiments, the indoor unit coil temperature is divided into three temperature zones, which are a first zone (T1, T2), a second zone (T2, T3), and a third zone (T3, T4), wherein T1< T2< T3< T4, and the corresponding wind speed modes are sequentially a breeze mode, a low wind mode, and a user-set mode, the breeze mode has a wind speed lower than the low wind mode, and the low wind mode has a wind speed lower than the user-set mode, for example, the temperature range of the first zone is greater than 25 degrees celsius and less than or equal to 32 degrees celsius, the temperature range of the second zone is greater than 32 degrees celsius and less than or equal to 34 degrees celsius, and the temperature range of the third zone is greater than 34 degrees and less than or equal to 40 degrees celsius, and the specific control process may be that the first coil temperature is 33 degrees celsius, the temperature zone in which the second zone is located, and the corresponding wind speed mode is the low wind mode, the air conditioner is controlled to operate in the low wind mode. The preset temperature interval in this embodiment is only meant by an exemplary illustration of the temperature interval, and the temperature interval is not specifically limited, and those skilled in the art can determine an appropriate temperature interval according to actual situations.
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 operation duration in the current wind speed mode; and if the current wind speed mode is the highest-level wind speed mode and the operation time reaches the preset time, controlling the wind speed mode to operate under the wind speed mode corresponding to the temperature of the first coil pipe.
Here, the reaching of the preset time length is used for expressing the condition that the air-conditioning air outlet is stable, that is, if the operation time length reaches the preset time length, the air-conditioning air outlet is stable.
Therefore, after the air conditioner runs for a long time and reaches the preset time, the air speed is adjusted according to the current temperature of the coil pipe of the indoor unit, and 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 reaches the preset time, the air conditioner controls the air conditioner to operate in the 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 time length is used to represent a condition that the temperature of the coil of the indoor unit rises to the lowest temperature of the temperature range corresponding to the next-stage wind speed mode, that is, if the operation time length of the air conditioner reaches the preset time length, it represents that the air conditioner can operate the next-stage wind speed mode corresponding to the current wind speed mode.
Therefore, the running speed of the fan of the indoor unit is controlled according to the wind speed mode, the heat exchange of the indoor unit can be accelerated, and the temperature of the coil pipe of the indoor unit can be quickly improved.
In some embodiments, the temperature of the coil pipe of the indoor unit 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 time duration is 4 minutes, and the specific control process can be that the current wind speed mode of the air conditioner is the breeze mode, the running time duration of the breeze mode is 3 minutes, and the air conditioner is controlled to run in the low wind mode when the running time duration reaches 4 minutes.
And step S03, the air conditioner continuously obtains the temperature of the second coil of the indoor unit, and controls the heat storage device to stop releasing heat when the temperature of the second coil reaches a second set threshold value.
In the disclosed embodiment, 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 wind of the air conditioner, the heat storage device is controlled to release heat to raise the temperature of the coil pipe of the indoor unit under the condition that the cold wind prevention function of the air conditioner is started; acquiring a first coil temperature of an indoor unit coil, and controlling an air conditioner to operate in a wind speed mode corresponding to the first coil temperature; and continuously acquiring the temperature of a second coil of the indoor unit coil, and controlling the heat storage device to stop releasing heat when the temperature of the second coil reaches a second set threshold value, namely controlling the heat storage device to continuously release heat when the temperature of the second coil is greater than or equal to the first set threshold value and less than the second set threshold value. Through controlling the heat storage device to release heat, the indoor coil pipe can be rapidly heated after the cold air prevention function is started, the cold air prevention time is shortened, and a user can quickly feel hot air blown out by the air conditioner after the heating starting-up is realized.
Fig. 2 is a schematic diagram of a control method for preventing cold air of an air conditioner according to an embodiment of the disclosure. As shown in fig. 2, the control method includes:
and step S11, controlling the heat storage device to store heat under the condition that the air conditioner determines that the indoor unit fan rotates.
Here, the heat stored in the heat storage device may be released when the cold wind prevention function is turned on to raise the temperature of the coil of the indoor unit.
And step S12, controlling the heat storage device to release heat to raise the temperature of the coil pipe of the indoor unit under the condition that the air conditioner determines that the air conditioner starts the cold air prevention function.
And step S13, the air conditioner acquires the first coil temperature of the coil of the indoor unit and controls the air conditioner to operate in a wind speed mode corresponding to the first coil temperature.
In step S14, the air conditioner controls the heat storage device to store heat when the first coil temperature reaches a first set threshold.
And step S15, the air conditioner continuously obtains the temperature of the second coil of the indoor unit, and controls the heat storage device to stop releasing heat when the temperature of the second coil reaches a second set threshold value.
In the disclosed embodiment, 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 the rotation of the fan of the indoor unit. Therefore, kinetic energy generated by rotation of the fan is effectively utilized, an electric heating device is not required to be additionally arranged, and the fan is energy-saving and environment-friendly.
By adopting the control method for preventing cold wind of the air conditioner, the heat storage device stores heat when the air conditioner normally operates, and the stored heat is used for increasing the temperature of the coil pipe of the indoor unit in the cold wind prevention process; after the cold air prevention function is started, the heat storage device releases heat so as to increase 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 a second set threshold, the thermal storage device stops releasing heat. Through controlling the heat storage device to release heat, the indoor coil pipe can be rapidly heated after the cold air prevention function is started, the cold air prevention time is shortened, and a user can quickly feel hot air blown out by the air conditioner after the heating starting-up is realized.
