step S14, adjusting the rotation speed of the first wind turbine 14 and the second wind turbine 16 to a first target rotation speed.
According to the control method of the fan of the air conditioner 100, the second wind wheel 16 is started first and then the first wind wheel 14 is started when the air conditioner is started according to the characteristics of the counter-rotating fan 12, so that the success rate of starting the counter-rotating fan 12 is improved, and the normal operation of the air conditioner 100 and the performance of the air conditioner 100 are ensured.
Specifically, the counter-rotating fan 12 may be installed at a heat exchanger beside the counter-rotating fan 12 to dissipate heat. In one embodiment, the counter-rotating fan 12 is an outdoor fan 22 of the air conditioner 100. In this way, the air volume requirement for the outdoor heat exchanger 24 can be satisfied.
Referring to fig. 2, the air conditioner 100 includes a compressor 18, a four-way reversing valve 20, an outdoor fan 22, an outdoor heat exchanger 24, a throttle member 26, an indoor fan 28, and an indoor heat exchanger 30. The compressor 18, the four-way reversing valve 20, the outdoor fan 22, the outdoor heat exchanger 24, and the throttling part 26 may be provided in an outdoor unit, and the indoor fan 28 and the indoor heat exchanger 30 may be provided in an indoor unit. The indoor heat exchanger 30 may function as an evaporator and the outdoor heat exchanger 24 may function as a condenser when the air conditioner 100 is cooling. The indoor heat exchanger 30 may function as a condenser and the outdoor heat exchanger 24 may function as an evaporator when the air conditioner 100 is heating.
In the embodiment shown in fig. 2 and 3, the counter-cyclone 12 is the outdoor fan 22, and the counter-cyclone 12 is disposed beside the outdoor heat exchanger 24. The counter-rotating fan 12 includes two stages of wind wheels: a first rotor 14 and a second rotor 16. The first wind wheel 14 may be driven by a first motor, the second wind wheel 16 may be driven by a second motor, and the first wind wheel 14, the first motor, the second wind wheel 16, and the second motor may be disposed in the outdoor unit wind cover 32.
The first wind wheel 14 is disposed near the outdoor heat exchanger 24, and the second wind wheel 16 is disposed far from the outdoor heat exchanger 24, near the outdoor fan guard 32. The blades of the first wind wheel 14 and the second wind wheel 16 are opposite in rotation direction during normal operation, so that opposite-rotation air flow is formed to blow out the air after heat exchange. Wherein first rotor 14 is upwind of the normal operation of second rotor 16.
In some embodiments, the operating frequency of the compressor 18 may range from 0Hz to 140 Hz. The operating range of the rotating speed of the first wind wheel 14 can be 0-1000 rpm, and the operating range of the rotating speed of the second wind wheel 16 can be 0-1000 rpm. It is understood that in other embodiments, the counter-rotating fan 12 may be used as the indoor fan 28 and the counter-rotating fan 12 may be disposed beside the indoor heat exchanger 30.
In the related art, one of the starting methods for the cyclone fan is: under the condition of receiving the start-up instruction, first wind wheel and second wind wheel start simultaneously, however, can make the starting current and the power of motor great like this, need adopt powerful motor, just can guarantee that first wind wheel and second wind wheel start successfully simultaneously and reach the target rotational speed, nevertheless can cause the volume increase of motor, and the cost rises. The other starting scheme is as follows: and under the condition of receiving the starting-up instruction, singly starting the first wind wheel, wherein the second wind wheel is a rear guide vane of the first wind wheel, and the rotating directions of the first wind wheel and the second wind wheel are the same. First wind wheel is the operation back of earlier starting alone, then can increase the start-up wind pressure of second wind wheel, can cause the motor starting torque who connects the second wind wheel to increase, causes the starting power and the starting current increase of second wind wheel, and the second wind wheel easily appears the start failure, or the second wind wheel can't reach the target rotational speed.
In the present embodiment, initially, the air conditioner 100 is in the off state, and both the first wind rotor 14 and the second wind rotor 16 of the counter-rotating fan 12 are in the shutdown state. Under the condition of receiving the starting instruction, the second wind wheel 16 can be independently started first, at this time, the first wind wheel 14 is a front guide vane of the second wind wheel 16, and the rotating directions of the first wind wheel 14 and the second wind wheel 16 are opposite. Under the condition that the second wind wheel 16 is started firstly and the rotating speed of the second wind wheel 16 reaches the second threshold rotating speed, the first wind wheel 14 is started, the wind pressure of the first wind wheel 14 is reduced, the starting power and the starting current of the first wind wheel 14 can be reduced, the first wind wheel 14 is started successfully, the whole operation of the counter-rotating fan 12 is facilitated, the target rotating speed is reached smoothly, and the target air volume requirement is met. After the first rotor 14 is started, the rotational speeds of the first rotor 14 and the second rotor 16 may be adjusted to a first target rotational speed.
The first target rotation speed may be a default rotation speed at the time of starting up, and the default rotation speed may be fixed or adjustable and stored. The first target rotating speed can be determined according to the starting instruction.
In one embodiment, first rotor 14 and second rotor 16 are coaxially disposed. Thus, the counter-rotating fan 12 can be operated more stably and can provide the target air volume.
In the present embodiment, the air conditioner 100 may be provided with the first threshold rotation speed and the second threshold rotation speed in advance. The first threshold rotational speed may be the rotational speed of the corresponding first wind rotor 14 at which the second wind rotor 16 may be activated. The second threshold rotational speed may be a rotational speed of the corresponding second wind rotor 16 at which the first wind rotor 14 may be activated. The first target rotational speed may be greater than or equal to the second threshold rotational speed.
In some embodiments, the operating range of the rotational speed of first wind turbine 14 when second wind turbine 16 may be started is 0 rpm to 450 rpm, and the operating range of the rotational speed of second wind turbine 16 when first wind turbine 14 may be started is 0 rpm to the maximum rotational speed of the second wind turbine, so that the successful start of first wind turbine 14 and second wind turbine 16 may be ensured.
Specifically, the rotation speed of the corresponding first wind turbine 14 when the second wind turbine 16 is activated, i.e. the first threshold rotation speed, may be selected from a range of 0 rpm to 450 rpm, and the rotation speed of the corresponding second wind turbine 16 when the first wind turbine 14 is activated, and the second threshold rotation speed may be selected from a range of 0 rpm to the highest rotation speed of the second wind turbine.
In some examples, the first threshold speed may be 0 rpm, 100 rpm, 200 rpm, 300 rpm, 400 rpm, or 450 rpm, or other values between 0 rpm and 450 rpm. The maximum speed of the second wind rotor 16 may be 1000 rpm and the second threshold speed may be 0 rpm, 100 rpm, 200 rpm, 300 rpm, 400 rpm, 500 rpm, or 1000 rpm, or other values between 0 rpm and 1000 rpm.
In some embodiments, referring to fig. 4, the control method includes:
step S20, when the air volume increase instruction is received and the second wind wheel 16 operates alone, the first wind wheel 14 is started;
and step S22, adjusting the rotation speed of the first wind wheel 14 and the second wind wheel 16 to a second target rotation speed.
Therefore, the first wind wheel 14 can be ensured to be started smoothly under the condition that the second wind wheel 16 operates alone, and finally the rotating speed of the first wind wheel 14 and the rotating speed of the second wind wheel 16 can reach the second target rotating speed, so that the target air volume requirement is met.
Specifically, when the air conditioner 100 is operated, the air volume of the cyclone 12 may need to be adjusted by the air conditioner 100 according to the operation requirement. The outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16 when receiving the air volume increase instruction. Under the condition that the second wind wheel 16 operates alone, the first wind wheel 14 of the pair of the cyclone fans 12 is in a shutdown state, the first wind wheel 14 can be directly started, and the rotating speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to reach a second target rotating speed, so that the target air volume requirement is met.
The second target rotational speed may be a default rotational speed, which may be fixed or adjustable and stored. The second target rotation speed may be determined to have a specific magnitude according to the air volume increase command. The second target rotational speed may be greater than the first target rotational speed. The second target rotational speed may be greater than or equal to a second threshold rotational speed.
In some embodiments, referring to fig. 5, the control method includes:
step S30, in the case that the air volume increase instruction is received and the first wind wheel 14 operates alone, stopping the first wind wheel 14 or reducing the rotation speed of the first wind wheel 14 to a first threshold rotation speed;
step S32, starting the second wind wheel 16;
and step S34, adjusting the rotation speeds of the first wind turbine 14 and the second wind turbine 16 to a second target rotation speed when the rotation speed of the second wind turbine 16 reaches a second threshold rotation speed.
Therefore, the second wind wheel 16 can be smoothly started under the condition that the first wind wheel 14 operates alone, and finally the rotating speeds of the first wind wheel 14 and the second wind wheel 16 can reach the second target rotating speed, so that the target air volume requirement is met.
Specifically, when the air conditioner 100 is operated, the air conditioner 100 may need to adjust the air volume of the cyclone 12 according to the operation requirement. When receiving the air volume increase instruction, the outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16. Under the condition that the first wind wheel 14 operates alone, it is indicated that the second wind wheel 16 of the pair of the cyclone fans 12 is in a shutdown state, at this time, the first wind wheel 14 is stopped or the rotating speed of the first wind wheel 14 is reduced to a first threshold rotating speed, so that the second wind wheel 16 can be started smoothly, and the rotating speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to a second target rotating speed, so that the target air volume requirement is met.
The second target speed may be a default speed, and the default speed may be fixed or adjustable and stored. The second target rotation speed may be determined to have a specific magnitude according to the air volume increase command. The second target rotation speed may be determined to have a specific magnitude according to the air volume increase command. The second target rotational speed may be greater than or equal to the first target rotational speed. The second target rotational speed may be greater than or equal to a second threshold rotational speed.
In some embodiments, referring to fig. 6, the control method includes:
step S40, when the air volume increase instruction is received, the second wind wheel 16 and the first wind wheel 14 both operate, and the rotation speed of the first wind wheel 14 is greater than that of the second wind wheel 16, reducing the rotation speed of the first wind wheel 14 to that of the second wind wheel 16;
and step S42, adjusting the rotation speed of the first wind wheel 14 and the second wind wheel 16 to a second target rotation speed.
Therefore, under the condition that the first wind wheel 14 and the second wind wheel 16 both operate and the rotating speed of the first wind wheel 14 is greater than that of the second wind wheel 16, the rotating speeds of the first wind wheel 14 and the second wind wheel 16 can reach a second target rotating speed, and the target air volume requirement is met.
Specifically, when the air conditioner 100 is operated, the air volume of the cyclone 12 may need to be adjusted by the air conditioner 100 according to the operation requirement. The outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16 when receiving the air volume increase instruction. Under the condition that the first wind wheel 14 and the second wind wheel 16 both operate and the rotating speed of the first wind wheel 14 is greater than that of the second wind wheel 16, the rotating speed of the first wind wheel 14 is reduced to that of the second wind wheel 16, and the rotating speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to a second target rotating speed, so that the target air volume requirement is met.
The second target speed may be a default speed, and the default speed may be fixed or adjustable and stored. The second target rotation speed may be determined to have a specific magnitude according to the air volume increase command. The second target rotational speed may be greater than or equal to the first target rotational speed. The second target rotational speed may be greater than or equal to a second threshold rotational speed.
In some embodiments, a control method comprises:
and under the conditions that an air volume increasing instruction is received, the second wind wheel 16 and the first wind wheel 14 operate, and the rotating speed of the first wind wheel 14 is not larger than that of the second wind wheel 16, adjusting the rotating speeds of the first wind wheel 14 and the second wind wheel 16 to a second target rotating speed.
Therefore, under the condition that the first wind wheel 14 and the second wind wheel 16 both operate and the rotating speed of the first wind wheel 14 is not larger than that of the second wind wheel 16, the rotating speeds of the first wind wheel 14 and the second wind wheel 16 can reach a second target rotating speed, and the target air volume requirement is met.
Specifically, when the air conditioner 100 is operated, the air conditioner 100 may need to adjust the air volume of the cyclone 12 according to the operation requirement. The outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16 when receiving the air volume increase instruction. Under the condition that the first wind wheel 14 and the second wind wheel 16 both operate and the rotating speed of the first wind wheel 14 is not greater than that of the second wind wheel 16, the rotating speeds of the first wind wheel 14 and the second wind wheel 16 can be directly adjusted to a second target rotating speed, and the target air volume requirement is met.
The second target speed may be a default speed, and the default speed may be fixed or adjustable and stored. The second target rotation speed may be determined to have a specific magnitude according to the air volume increase instruction. The second target rotational speed may be greater than or equal to the first target rotational speed. The second target rotational speed may be greater than or equal to a second threshold rotational speed.
In some embodiments, the speed of adjustment of the rotational speed of second rotor 16 leads the speed of adjustment of the rotational speed of first rotor 14. In this way, it is further ensured that the rotational speed of the second wind turbine 16 can reach the target rotational speed.
Specifically, in the process of adjusting the rotation speed of the first wind turbine 14 and the rotation speed of the second wind turbine 16 to the target rotation speed, if the rotation speed of the first wind turbine 14 is greater than the rotation speed of the second wind turbine 16, the wind pressure of the second wind turbine 16 is greater, so that the second wind turbine 16 is slowed down, and even cannot reach the target rotation speed.
In order to further ensure that the rotating speed of the second wind wheel 16 can reach the target rotating speed, in the process of adjusting the rotating speed of the first wind wheel 14 and the rotating speed of the second wind wheel 16 to the target rotating speed, the adjusting speed of the rotating speed of the second wind wheel 16 is higher than the adjusting speed of the rotating speed of the first wind wheel 14, so that in the adjusting process, the rotating speed of the second wind wheel 16 is higher than the rotating speed of the first wind wheel 14, the wind pressure of the second wind wheel 16 is lower, and the rotating speed of the second wind wheel 16 and the rotating speed of the first wind wheel 14 can both reach the target rotating speed.
In one embodiment, the adjusting process may be divided into a plurality of stages performed in time sequence, and each stage may correspond to a time range. The time ranges corresponding to the different phases may be the same or different. The initial rotation speed of the latter stage is the ending rotation speed of the former stage. At the end of each phase, the rotational speed of the second wind rotor 16 is greater than the rotational speed of the first wind rotor 14. In other embodiments, the rotational acceleration of second rotor 16 may be greater than the rotational acceleration of first rotor 14 such that the rotational speed of second rotor 16 is adjusted at a rate that is faster than the rotational speed of first rotor 14.
In some embodiments, the speed of adjustment of the rotational speed of the second wind rotor 16 is synchronized with the speed of adjustment of the rotational speed of the first wind rotor 14. In this way, it is further ensured that the rotational speed of the second wind turbine 16 can reach the target rotational speed.
Specifically, in the process of adjusting the rotation speed of the first wind turbine 14 and the rotation speed of the second wind turbine 16 to the target rotation speed, if the rotation speed of the first wind turbine 14 is greater than the rotation speed of the second wind turbine 16, the wind pressure of the second wind turbine 16 is greater, so that the second wind turbine 16 is slowed down, and even cannot reach the target rotation speed.
In order to further ensure that the rotating speed of the second wind wheel 16 can reach the target rotating speed, in the process of adjusting the rotating speed of the first wind wheel 14 and the rotating speed of the second wind wheel 16 to the target rotating speed, the adjusting speed of the rotating speed of the second wind wheel 16 is synchronous with the adjusting speed of the rotating speed of the first wind wheel 14, so that in the adjusting process, the rotating speed of the second wind wheel 16 is basically equal to the rotating speed of the first wind wheel 14, the wind pressure of the second wind wheel 16 is small, and the rotating speed of the second wind wheel 16 and the rotating speed of the first wind wheel 14 can reach the target rotating speed. The rotation speed of the second wind rotor 16 is substantially equal to the rotation speed of the first wind rotor 14, and it is understood that the rotation speed of the second wind rotor 16 is completely equal to the rotation speed of the first wind rotor 14, or the difference between the rotation speeds is within a preset range.
In one embodiment, the adjustment process may be divided into a plurality of stages performed in time sequence, and each stage may correspond to a time range. The time ranges corresponding to the different phases may be the same or different. The initial rotation speed of the latter stage is the ending rotation speed of the former stage. At the end of each phase, the rotational speed of second rotor 16 is substantially equal to the rotational speed of first rotor 14. In other embodiments, it is also possible that the rotational acceleration of the second wind rotor 16 is substantially equal to the rotational acceleration of the first wind rotor 14, such that the speed of adjustment of the rotational speed of the second wind rotor 16 is synchronized with the speed of adjustment of the rotational speed of the first wind rotor 14.
