All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a flowchart of a control method of an air conditioner according to a first embodiment of the present invention is shown. With reference to fig. 1 and 2, the control method of the air conditioner includes, for example, the following steps: controlling the air conditioner to start and continuously run; acquiring the temperature of an electric control device of the outdoor fan in real time; controlling the operating parameters of the air conditioner according to the temperature of the electric control device of the outdoor fan; wherein the operating parameters include at least one or a combination of: the rotation speed of the outdoor fan, the rotation speed of the indoor fan, the running frequency of the compressor and the running mode of the air conditioner.
For example, an outdoor unit temperature sensor is provided in the outdoor unit controller. The outdoor unit temperature sensor can acquire the temperature of the electric control device of the outdoor fan in real time and transmit the temperature to the controller in a signal transmission mode, so that the controller can adjust the operating parameters of the air conditioner in time when the temperature of the electric control device of the outdoor fan exceeds the standard.
Specifically, under the condition that the temperature of an electric control device of the outdoor unit of the air conditioner is too high, especially the temperature of the electric control device of the outdoor fan is too high, the electric control device of the outdoor fan can be timely cooled by adjusting at least one or a combination of the rotating speed of the outdoor fan, the rotating speed of the indoor fan, the operating frequency of a compressor and the operating mode of the air conditioner, so that the problem that the outdoor unit controller is damaged due to the fact that the temperature of the electric control device of the outdoor unit is too high is effectively solved, normal operation of the electric control device of the outdoor unit is guaranteed, the service lives of the electric control device of the outdoor unit and the air conditioner are prolonged, and the use satisfaction of users is improved.
In a specific embodiment, the outdoor unit electric control device can be cooled by adjusting the rotating speed of the outdoor fan; the electric control device of the outdoor unit can be cooled by adjusting the rotating speed of the outdoor fan and combining with the rotating speed of the indoor fan; the outdoor unit electric control device can be cooled by combining the regulation of the rotating speed of the outdoor fan, the regulation of the rotating speed of the indoor fan and the regulation of the running frequency of the compressor; the outdoor unit electric control device may also be cooled by adjusting the operation mode of the air conditioner, which is not limited herein.
Further, the controlling the operation parameters of the air conditioner according to the temperature of the electric control device of the outdoor fan comprises: and if the temperature of the electric control device of the outdoor fan is greater than a first temperature threshold value, controlling the rotating speed of the outdoor fan to be reduced.
If the temperature of the electric control device of the outdoor fan is greater than the first temperature threshold value, the temperature of the electric control device of the outdoor fan is indicated to exceed the temperature range allowed by the normal operation of the air conditioner, so that the operation load of the outdoor fan is reduced in a mode of reducing the rotating speed of the outdoor fan, the whole outdoor fan is cooled, the electric control device of the outdoor fan is cooled, the problem that the outdoor unit controller is damaged due to the fact that the temperature of the electric control device of the outdoor fan is too high is solved, and the normal heat exchange operation of the outdoor unit is guaranteed.
For example, the preferred value of the first temperature threshold is 90 ℃ and the reduction value of the outdoor fan speed is 100 revolutions. In one embodiment, if the temperature of the electric control device of the outdoor fan is greater than 90 ℃, the rotating speed of the outdoor fan is controlled to be reduced by 100 revolutions.
Further, after the rotating speed of the outdoor fan is reduced, the air conditioner is controlled to continuously operate for a first preset time at the reduced rotating speed of the outdoor fan; and then the rotating speed of the indoor fan is controlled according to the relation between the temperature of the electric control device of the outdoor fan and the first temperature threshold value.
Because the adjustment range of the rotating speed of the outdoor fan is limited, if the temperature of the electric control device of the outdoor fan is still greater than the first temperature threshold value after the rotating speed of the outdoor fan is reduced, the temperature of the electric control device of the outdoor fan is further reduced in a mode of controlling the rotating speed of the indoor fan after the air conditioner continuously operates for a first preset time period at the reduced rotating speed of the outdoor fan, namely, in a mode of controlling the integral operation load of the air conditioner.
Further, if the temperature of the electric control device of the outdoor fan is greater than a first temperature threshold value, controlling the air conditioner to continue to operate at the reduced rotating speed of the outdoor fan and controlling the rotating speed of the indoor fan to be reduced; and if the temperature of the electric control device of the outdoor fan is less than or equal to the first temperature threshold value for a second preset time, controlling the air conditioner to continuously operate according to the current operation parameters. Preferably, the preferred value of the first preset time duration is 30min, and the preferred value of the second preset time duration is 30 min.
Specifically, if the temperature of the electric control device of the outdoor fan is greater than the first temperature threshold, it is indicated that the temperature of the electric control device of the outdoor fan cannot be reduced to the optimal temperature range only by reducing the rotating speed of the outdoor fan, so that the temperature of the electric control device of the outdoor fan is further reduced by controlling the rotating speed of the indoor fan to be reduced, namely by reducing the operating load of the whole air conditioner, on the basis of controlling the air conditioner to continue to operate at the reduced rotating speed of the outdoor fan. If the temperature of the electric control device of the outdoor fan is less than or equal to the first temperature threshold value for the second preset time, the temperature of the electric control device of the outdoor fan is reduced to the optimal temperature range and is stabilized in the optimal temperature range, and therefore the air conditioner is controlled to continue to operate according to the current operation parameters without further adjustment. Preferably, the indoor fan rotation speed reduction value is 100 revolutions.
In a specific embodiment, when the rotating speed of the outdoor fan is reduced by 100 revolutions and the air conditioner continuously operates for 30min at the reduced rotating speed of the outdoor fan, if the temperature of the electric control device of the outdoor fan is still greater than 90 ℃, the rotating speed of the indoor fan is reduced by 100 revolutions; if the temperature of the electric control device of the outdoor fan is less than or equal to 90 ℃, the air conditioner is controlled to continuously operate according to the current operation parameters without reducing the rotating speed of the indoor fan.
Further, the controlling the operation parameters of the air conditioner according to the temperature of the electric control device of the outdoor fan further comprises: controlling the air conditioner to continuously run for a third preset time at the reduced rotating speed of the indoor fan; and controlling the running frequency of the compressor according to the relation between the temperature of the electric control device of the outdoor fan and the first temperature threshold value. Preferably, the preferred value of the third preset time period is 30 min.
Because the adjustment range of the rotating speed of the indoor fan is limited, if the temperature of the outdoor fan electric control device is still not adjusted to the optimal temperature range after the air conditioner is controlled to continuously operate at the reduced rotating speed of the indoor fan for the third preset time, the operation load of the whole air conditioner can be controlled in a mode of controlling the operation frequency of the compressor, so that the temperature of the outdoor fan electric control device is controlled in the optimal range, and the stable operation of the whole air conditioner is ensured.
In a specific embodiment, if the temperature of the electric control device of the outdoor fan is still higher than 90 ℃ after the air conditioner continuously operates for 30min at the rotating speed of the indoor fan reduced by 100 revolutions, the temperature of the electric control device of the outdoor fan is further reduced by controlling the operating frequency of the compressor.
Further, the controlling the operation frequency of the compressor according to the magnitude relation between the temperature of the outdoor fan electric control device and the first temperature threshold value comprises: if the temperature of the electric control device of the outdoor fan is greater than a first temperature threshold value, controlling the air conditioner to continue to operate at the reduced rotating speed of the indoor fan and controlling the operating frequency of the compressor to be reduced; and if the temperature of the electric control device of the outdoor fan is less than or equal to the first temperature threshold value for a fourth preset time, controlling the air conditioner to continuously operate according to the current operation parameters. Preferably, the preferred value of the fourth preset time period is 30min, and the reduction value of the running frequency of the compressor is 2 Hz.
If the temperature of the electric control device of the outdoor fan is larger than the first temperature threshold, the temperature of the electric control device of the outdoor fan cannot be reduced to the optimal temperature range by reducing the rotating speed of the outdoor fan and reducing the rotating speed of the indoor fan, so that the air conditioner is controlled to continue to operate at the reduced rotating speed of the indoor fan and the operating frequency of the compressor is controlled to be reduced, the operating load of the whole air conditioner is further reduced by reducing the operating frequency of the compressor, and the temperature of the electric control device of the outdoor fan is reduced to the optimal temperature range. If the temperature of the electric control device of the outdoor fan is less than or equal to the first temperature threshold value for the fourth preset time, the temperature of the electric control device of the outdoor fan is reduced to the optimal temperature range and is stabilized in the optimal temperature range, so that the air conditioner is controlled to continuously operate according to the current operation parameters without further adjustment.
In a specific embodiment, if the temperature of the electric control device of the outdoor fan is greater than 90 ℃, it indicates that the temperature of the electric control device of the outdoor fan cannot be reduced to the optimal temperature range when the rotating speed of the outdoor fan is reduced by 100 revolutions and the rotating speed of the indoor fan is reduced by 100 revolutions, and therefore, on the basis that the rotating speed of the outdoor fan is reduced by 100 revolutions and the rotating speed of the indoor fan is reduced by 100 revolutions, the operating frequency of the compressor is controlled to be reduced by 2Hz, so that the operating load of the whole air conditioner is reduced without affecting user experience, and the temperature of the electric control device of the outdoor fan is reduced to the optimal temperature range.
Further, the controlling the operation parameters of the air conditioner according to the temperature of the electric control device of the outdoor fan further comprises: controlling the air conditioner to continuously run for a fifth preset time period at the reduced running frequency of the compressor; and controlling the operation mode of the air conditioner according to the relation between the temperature of the electric control device of the outdoor fan and the first temperature threshold value. Preferably, the preferred value of the fifth preset time period is 30 min.
In order to ensure the normal heat exchange process between the indoor unit of the air conditioner and the indoor environment, after the air conditioner continuously operates for a fifth preset time period at the reduced operation frequency of the compressor, even if the temperature of the electric control device of the outdoor fan is still not adjusted to the optimal temperature range, the operation frequency of the compressor cannot be continuously reduced, so that the electric control device of the outdoor fan needs to be cooled in a mode of controlling the operation mode of the air conditioner so as to rapidly reduce the temperature of the electric control device of the outdoor fan to the optimal temperature range, and therefore the stable operation of the whole air conditioner is ensured.
Further, the operation mode of controlling the air conditioner according to the temperature of the electric control device of the outdoor fan comprises the following steps: if the temperature of the electric control device of the outdoor fan is greater than a first temperature threshold value, controlling the operation parameters to be restored to an initial value, and controlling the air conditioner to enter a heating mode; and if the temperature of the electric control device of the outdoor fan is less than or equal to the first temperature threshold value for a sixth preset time, controlling the air conditioner to continuously operate according to the current operation parameters.
If the temperature of the outdoor fan electric control device is larger than the first temperature threshold value, the operation frequency of the compressor is reduced, the rotating speed of the outdoor fan is reduced, and the rotating speed of the indoor fan is reduced, so that the temperature of the outdoor fan electric control device cannot be reduced to an optimal temperature range, the three operation parameters are controlled to be recovered to initial values, the air conditioner is controlled to enter a heating mode, and the low-temperature environment of the condenser is used for cooling the outdoor fan electric control device.
