When the air conditioner is in heating operation, in order to prevent the air outlet temperature from being too low, cold air prevention treatment can be carried out. In the embodiment of the disclosure, in the process of cold wind prevention treatment of the air conditioner operated in the heating mode, after the indoor fan is not operated when the wind speed is reduced from a higher wind speed to a zero wind speed, the operation current of the air conditioner can be monitored, and when the operation current reaches a set value, the indoor fan is controlled to rotate reversely and the electric heating is started, so that the temperature of the coil pipe in the air conditioner can be quickly increased to reach the set value corresponding to the start of the indoor fan in the cold wind prevention treatment, thereby avoiding that the operation current of the air conditioner is rapidly increased to exceed the preset shutdown protection current, reducing the probability of shutdown of the air conditioner caused by cold wind release treatment, improving the stability and efficacy of the cold wind prevention treatment of the heating air conditioner, and further improving the.
Fig. 1 is a schematic flow chart of a control method for an air conditioner fan according to an embodiment of the present disclosure. As shown in fig. 1, a process for air-conditioning blower control includes:
step 101: when the air conditioner indoor fan in the heating mode operation is not operated when the air conditioner indoor fan is operated from a first direction and a first gear wind speed to a zero wind speed, a first current operation current value and a first current inner coil temperature of the air conditioner are obtained.
In the embodiment of the disclosure, the air conditioner still performs cold air prevention treatment in the heating mode operation process. In some embodiments, the cold air prevention process comprises: under the condition that the temperature of the inner coil pipe is lower than a first set temperature, controlling the indoor fan to stop running; controlling the indoor fan to operate at a first direction and a second gear speed under the condition that the temperature of the inner coil pipe is greater than or equal to a first set temperature and less than a second set temperature; controlling the indoor fan to operate in a first direction and a first gear of wind speed under the condition that the current temperature of the inner coil pipe is greater than or equal to a third set temperature; and the third set temperature is greater than or equal to the second set temperature, and the first gear wind speed is greater than the second gear wind speed.
The operating speed of the indoor fan in each air conditioner is not divided identically, wherein the first gear wind speed may be the highest divided wind speed, and the second gear wind speed may be the lowest divided wind speed. For example: the first direction is a forward rotation direction of the indoor fan, the first gear wind speed is a preset high wind speed, the second gear wind speed is a preset micro wind speed, the first set temperature is 23 ℃, the second set temperature and the third set temperature are both 28 ℃, and therefore, if the temperature of the inner coil pipe is 27 ℃, the indoor fan can be controlled to operate at the preset micro wind speed in a forward rotation mode. If the temperature of the inner coil pipe is 31 ℃, the indoor fan can be controlled to operate in a forward rotation mode at a preset high wind speed. And if the temperature of the inner coil pipe is 20 ℃, the indoor fan can be controlled to stop running.
Of course, the indoor fan operation speed may be divided into other parts, so in some embodiments, the third set temperature is greater than the second set temperature, so that the indoor fan is controlled to operate in the first direction and the third speed in the case that the inner coil temperature is greater than or equal to the second set temperature and less than the third set temperature; the first gear wind speed is greater than the third gear wind speed, and the third gear wind speed is greater than the second gear wind speed.
For example: the first direction is the forward rotation direction of the indoor fan, the first gear wind speed is the preset high wind speed, the second gear wind speed is the preset micro wind speed, the third gear wind speed is the preset low wind speed, the first set temperature is 23 ℃, the second set temperature is 28 ℃, and the third set temperature is 30 ℃, so that if the temperature of the inner coil pipe is 29 ℃, the indoor fan can be controlled to operate in forward rotation at the preset low wind speed.
The cold wind processing is prevented in the heating operation process, after the temperature of the coil pipe in the air conditioner reaches the third set temperature, the fan in the air conditioner operates at the first direction and the first gear of wind speed, however, the temperature of the coil pipe in the air conditioner is lowered, the condition that the temperature of the coil pipe in the air conditioner is smaller than the first set temperature is met, and the fan in the air conditioner stops operating.
When the air conditioner indoor fan in the heating mode does not operate when the air conditioner indoor fan operates from a first direction and a first gear wind speed to a zero wind speed, the operation current value and the temperature of the inner coil pipe of the air conditioner can be obtained in real time or at regular time, and the operation current value and the temperature of the inner coil pipe are the first current operation current value and the first current inner coil pipe temperature when the acquisition time is reached each time.
Step 102: and under the condition that the first current temperature of the inner coil is lower than the first set temperature and the first current running current value is greater than or equal to the first current value, starting the electric heating and controlling the indoor fan to run in a second direction and a second wind speed.
A safety current threshold value, namely a first current value, can be preset according to the shutdown risk degree of the air conditioner, when the first current running current value reaches the first current value, the shutdown risk exists, protection processing is needed, and the shutdown probability is reduced. Therefore, according to the cold wind prevention process, when the first current inner coil temperature is less than the first set temperature, the indoor fan of the air conditioner stops operating, but in the embodiment of the disclosure, when the first current inner coil temperature is less than the first set temperature and the first current operation current value is greater than or equal to the first current value, the electric heating may be started and the indoor fan may be controlled to operate in the second direction and the second speed. The second direction is opposite to the first direction. Like this, open electrical heating, the motor is with opposite direction operation, and low wind speed heats the interior coil pipe with the heat of electricity auxiliary heat for the speed that interior coil pipe temperature rises in time gives the system pressure release, has reduced the probability that the air conditioner shut down.
The first current value can be set according to the performance of the air conditioner, the shutdown probability and the like. In some embodiments, after the air conditioner is started to heat, the corresponding operating current value of the indoor fan when the indoor fan operates at the first direction and the second gear wind speed for the first time is obtained and recorded as the first current value. For example: the second-gear wind speed is the preset micro wind speed, the first direction is the positive rotation direction of the motor, after the air conditioner is started, the corresponding running current value when the indoor fan runs in positive rotation at the preset micro wind speed for the first time is obtained and recorded as the first current value IMicro-meter。
Of course, in the case where the first current inner coil temperature is greater than or equal to the first set temperature, the windproof treatment may be directly run, including: controlling the indoor fan to operate at a first direction and a second gear speed under the condition that the temperature of the first current inner coil pipe is greater than or equal to a first set temperature and less than a second set temperature; controlling the indoor fan to operate in a first direction and a first gear speed under the condition that the temperature of the first current inner coil is greater than or equal to a third set temperature; wherein the third set temperature is greater than or equal to the second set temperature. In some embodiments, the indoor fan is controlled to operate at a first direction and a third speed under the condition that the temperature of the first current inner coil is greater than or equal to a second set temperature and less than a third set temperature; the first gear wind speed is greater than the third gear wind speed, and the third gear wind speed is greater than the second gear wind speed.
And after the electric heating is started and the indoor fan is controlled to operate at a second direction and a second gear of wind speed, the temperature of the inner coil pipe rises rapidly, the operation current value and the temperature of the inner coil pipe are continuously acquired, and the windproof treatment is continuously carried out. Due to the electric heating, in some embodiments, the first set temperature may be further modified to increase the first set temperature, so that after the indoor fan is controlled to operate in the second direction and the second wind speed, the method further includes: acquiring a second current running current value of the air conditioner and a second current temperature of the inner coil; controlling the indoor fan to operate in a first direction and a second gear speed under the condition that the temperature of the second current inner coil is greater than or equal to the first correction set temperature; wherein the first correction setting temperature is the sum of the first setting temperature and the setting correction value.
For example: the first set temperature is 23 deg.c and the set correction value is 2 deg.c, so that the first set temperature may be 25 deg.c, and when the second current inner coil temperature is greater than or equal to 25 deg.c, the indoor fan may be controlled to operate in the first direction and the second speed, i.e. the inner fan is started.
In some embodiments, although the electric heating is performed, the temperature of the inner coil does not reach the first set temperature or the first corrected set temperature in a later time, and the operation current value of the air conditioner still continues to increase, at this time, the risk of the air conditioner being shut down is great, and the inner fan needs to be forced to start in the first direction, that is, the indoor fan is controlled to operate in the first direction and the second gear wind speed under the condition that the second current temperature of the inner coil is less than the first corrected set temperature and the second current value of the operation current is greater than or equal to the second current value; wherein the second current value is greater than the first current value.
Similarly, the second current value and the first current value can be configured according to the performance of the air conditioner and the shutdown risk degree. Or, in some embodiments, the rootAnd determining a correction current according to the preset shutdown protection current and the first current value, and determining the sum of the first current value and the correction current as a second current value. For example: presetting shutdown protection current IStopFirst current value IMicro-meterThus, can be (I)Stop-IMicro-meter) /2 is determined as the correction current, and IMicro-meter+(IStop-IMicro-meter) The second current value is determined as/2.
It can be seen that, in the embodiment, in the cold wind prevention processing of the air conditioner operating in the heating mode, after the indoor fan is not operated when the wind speed is reduced from a high wind speed to a zero wind speed, the operating current of the air conditioner can be monitored, and when the operating current reaches a set value, the indoor fan is controlled to rotate reversely and start electrical heating, so that the temperature of the coil pipe in the air conditioner can be rapidly increased to reach the set value corresponding to the start of the indoor fan, the condition that the operating current of the air conditioner rapidly rises and exceeds the preset shutdown protection current is avoided, the probability of shutdown of the air conditioner due to cold wind release processing is reduced, the stability and the efficacy of the cold wind prevention processing of the heating air conditioner are improved, and the.
The following operational flow is integrated into a specific embodiment to illustrate the control process for the air-conditioning fan provided by the embodiment of the present invention.
In this embodiment, in the cold wind prevention process, the wind speed is only divided into a first-gear wind speed, a second-gear wind speed and a zero wind speed, where the first-gear wind speed is a preset high wind speed, and the second-gear wind speed is a preset low wind speed. And the first direction is the positive rotation direction of the motor of the indoor fan, the second direction is the negative rotation direction of the motor of the indoor fan, the first set temperature is 24 ℃, and the second set temperature is equal to the third set temperature and is 29 ℃. And recording the corresponding running current value, namely a first current value I, when the indoor fan operates in positive rotation at a preset low wind speed for the first time after the air conditioner is started for heatingIs low in。
