To simplify the present disclosure, components and arrangements of specific examples are described herein. They are, of course, merely examples and are not intended to limit the application.
Referring to fig. 1 to 3, an embodiment of the present application provides a method for controlling a fan of an air conditioner 100, the air conditioner 100 includes a counter-rotating fan 12, the counter-rotating fan 12 includes a first wind wheel 14 and a second wind wheel 16, the first wind wheel 14 is disposed close to a heat exchanger, the second wind wheel 16 is disposed far from the heat exchanger, and the method includes:
Step S10, under the condition of receiving a starting instruction, starting the second wind wheel 16;
step S12, starting the first wind wheel 14 when the rotation speed of the second wind wheel 16 reaches the second threshold rotation speed;
in step S14, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the first target rotational 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 according to the characteristics of the counter-rotating fan 12 when the air conditioner is started, 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 cyclone 12 may be mounted to radiate heat in a heat exchanger located beside the cyclone 12. In one embodiment, the counter-rotating fan 12 is an outdoor fan 22 of the air conditioner 100. In this way, the air volume demand on 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 throttle member 26 may be disposed in an outdoor unit, and the indoor fan 28 and the indoor heat exchanger 30 may be disposed in an indoor unit. When the air conditioner 100 is cooling, the indoor heat exchanger 30 may be an evaporator, and the outdoor heat exchanger 24 may be a condenser. The indoor heat exchanger 30 may be used as a condenser and the outdoor heat exchanger 24 may be used as an evaporator when the air conditioner 100 heats.
In the embodiment shown in fig. 2 and 3, the counter-rotating fan 12 is an outdoor fan 22, and the counter-rotating fan 12 is disposed beside an outdoor heat exchanger 24. The counter-rotating fan 12 comprises two stages of wind wheels: a first wind wheel 14 and a second wind wheel 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 casing 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 unit fan housing 32. The blades of the first wind wheel 14 and the second wind wheel 16 are rotated in opposite directions during normal operation, so that the air after heat exchange is blown out by the counter-rotating air flow. Wherein the first wind wheel 14 is upwind of the normal operation of the second wind wheel 16.
In some embodiments, the operating frequency of the compressor 18 may be in the range of 0 to 140Hz. The rotational speed of the first rotor 14 may be in the range of 0 to 1000 rpm and the rotational speed of the second rotor 16 may be in the range of 0 to 1000 rpm. It will be appreciated that in other embodiments, the counter-rotating fan 12 may be 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 of the cyclone is: under the condition that a starting instruction is received, the first wind wheel and the second wind wheel are started simultaneously, however, the starting current and the power of the motor are larger, the high-power motor is required to be adopted, the first wind wheel and the second wind wheel can be ensured to be started successfully simultaneously and reach the target rotating speed, the volume of the motor is increased, and the cost is increased. Another starting scheme is: under the condition that a starting-up instruction is received, the first wind wheel is singly started, at the moment, the second wind wheel is a rear guide vane of the first wind wheel, and the rotation directions of the first wind wheel and the second wind wheel are the same. After the first wind wheel is started and operated independently, the starting wind pressure of the second wind wheel is increased, the starting torque of a motor connected with the second wind wheel is increased, the starting power and the starting current of the second wind wheel are increased, the second wind wheel is easy to start failure, or the second wind wheel cannot reach the target rotating speed.
In the embodiment of the present application, initially, the air conditioner 100 is in the off state, and both the first wind wheel 14 and the second wind wheel 16 of the cyclone 12 are in the off state. Under the condition that a starting-up instruction is received, the second wind wheel 16 can be started independently, at this time, the first wind wheel 14 is a front guide vane of the second wind wheel 16, and the rotation 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 first and the rotation speed of the second wind wheel 16 reaches the second threshold rotation speed, the first wind wheel 14 is started again, the wind pressure to 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 easy to start successfully, the operation of the whole disrotatory fan 12 is facilitated, the target rotation speed is achieved smoothly, and the requirement of target wind quantity is met. After the first wind wheel 14 is started, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 may be adjusted to a first target rotational speed.
The first target rotation speed may be a default rotation speed at startup, and the default rotation speed at startup may be fixed or adjustable and stored. The magnitude of the first target rotational speed may also be determined in accordance with a power-on command.
In one embodiment, the first rotor 14 and the second rotor 16 are coaxially disposed. Thus, the operation of the cyclone 12 can be made more stable and the target air volume can be provided.
In the present embodiment, the air conditioner 100 may be preset with a first threshold rotation speed and a second threshold rotation speed. The first threshold rotational speed may be a rotational speed of the corresponding first rotor 14 when the second rotor 16 is activatable. The second threshold rotational speed may be a rotational speed of a corresponding second rotor 16 when the first rotor 14 is activatable. 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 the corresponding first wind wheel 14 when the second wind wheel 16 can be started is 0 rpm to 450 rpm, and the operating range of the rotational speed of the corresponding second wind wheel 16 when the first wind wheel 14 can be started is 0 rpm to the highest rotational speed of the second wind wheel, so that the successful start of the first wind wheel 14 and the second wind wheel 16 can be ensured.
Specifically, the rotational speed of the corresponding first wind wheel 14 when the second wind wheel 16 is started, i.e. the first threshold rotational speed may be selected from the range of 0 rpm to 450 rpm, and the rotational speed of the corresponding second wind wheel 16 when the first wind wheel 14 is started may be selected from the highest rotational speed of the range of 0 rpm to the second wind wheel.
In some examples, the first threshold rotational 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 rotational speed of the second rotor 16 may be 1000 rpm and the second threshold rotational speed may be 0 rpm, 100 rpm, 200 rpm, 300 rpm, 400 rpm, 500 rpm or 1000 rpm or some other value between 0 rpm and 1000 rpm.
In some embodiments, referring to fig. 4, the control method includes:
Step S20, when an air volume increasing command is received and the second wind wheel 16 operates alone, starting the first wind wheel 14;
In step S22, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the second target rotational speed.
Therefore, under the condition that the second wind wheel 16 independently operates, the first wind wheel 14 can be ensured to be started smoothly, 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 quantity requirement is met.
Specifically, when the air conditioner 100 is operating, the air conditioner 100 may need to adjust the air volume of the cyclone 12 due to the working condition requirement. Upon receiving the air volume increasing command, the outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16. Under the condition that the second wind wheel 16 operates independently, the first wind wheel 14 of the pair of fans 12 is in a stop 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, or the default rotational speed may be fixed, or may be adjustable and stored. The second target rotational speed may be determined to be a specific value 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, under the condition that the wind volume increasing command is received and the first wind wheel 14 operates independently, 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;
In step S34, when the rotational speed of the second wind wheel 16 reaches the second threshold rotational speed, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the second target rotational speed.
Therefore, under the condition that the first wind wheel 14 independently operates, the second wind wheel 16 can be ensured to be smoothly started, 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 operating, the air conditioner 100 may need to adjust the air volume of the cyclone 12 due to the working condition requirement. When receiving the air volume increasing command, 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 independently, it indicates that the second wind wheel 16 of the pair of fans 12 is in a stop state, at this time, the first wind wheel 14 is stopped or the rotation speed of the first wind wheel 14 is reduced to a first threshold rotation speed, so as to ensure that the second wind wheel 16 can be started smoothly, and the rotation speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to a second target rotation speed, so as to meet the target air volume requirement.
The second target rotational speed may be a default rotational speed, and the default rotational speed may be fixed or adjustable and stored. The second target rotational speed may be determined to be a specific value according to the air volume increase command. The second target rotational speed may be determined to be a specific value 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 wind volume increasing command is received, the second wind wheel 16 and the first wind wheel 14 are all operated, and the rotation speed of the first wind wheel 14 is greater than the rotation speed of the second wind wheel 16, reducing the rotation speed of the first wind wheel 14 to the rotation speed of the second wind wheel 16;
In step S42, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the second target rotational speed.
In this way, when the first wind wheel 14 and the second wind wheel 16 both operate and the rotation speed of the first wind wheel 14 is greater than that of the second wind wheel 16, the rotation speeds of the first wind wheel 14 and the second wind wheel 16 can reach the second target rotation speed, and the target air volume requirement is met.
Specifically, when the air conditioner 100 is operating, the air conditioner 100 may need to adjust the air volume of the cyclone 12 due to the working condition requirement. Upon receiving the air volume increasing command, the outdoor unit detects the states of the first wind wheel 14 and the second wind wheel 16. Under the condition that both the first wind wheel 14 and the second wind wheel 16 operate and the rotating speed of the first wind wheel 14 is larger than that of the second wind wheel 16, firstly reducing the rotating speed of the first wind wheel 14 to that of the second wind wheel 16, and adjusting the rotating speeds of the first wind wheel 14 and the second wind wheel 16 to a second target rotating speed to meet the target air volume requirement.
The second target rotational speed may be a default rotational speed, and the default rotational speed may be fixed or adjustable and stored. The second target rotational speed may be determined to be a specific value 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 certain embodiments, the control method comprises:
And when the wind volume increasing command is received, the second wind wheel 16 and the first wind wheel 14 all operate, and the rotating speed of the first wind wheel 14 is not greater than the rotating speed of the second wind wheel 16, the rotating speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the second target rotating speed.
In this way, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 can reach the second target rotational speed under the condition that the first wind wheel 14 and the second wind wheel 16 both operate and the rotational speed of the first wind wheel 14 is not greater than the rotational speed of the second wind wheel 16, so as to meet the target air volume requirement.
Specifically, when the air conditioner 100 is operating, the air conditioner 100 may need to adjust the air volume of the cyclone 12 due to the working condition requirement. Upon receiving the air volume increasing command, 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 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 the second target rotating speed, so that the target air volume requirement is met.
The second target rotational speed may be a default rotational speed, and the default rotational speed may be fixed or adjustable and stored. The second target rotational speed may be determined to be a specific value 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, the adjustment speed of the rotational speed of the second rotor 16 leads the adjustment speed of the rotational speed of the first rotor 14. In this way, it can be further ensured that the rotational speed of the second wind wheel 16 can reach the target rotational speed.
Specifically, in the process of adjusting the rotation speed of the first wind wheel 14 and the rotation speed of the second wind wheel 16 to the target rotation speed, if the rotation speed of the first wind wheel 14 is greater than the rotation speed of the second wind wheel 16, the wind pressure of the second wind wheel 16 is caused to be greater, so that the second wind wheel 16 is slowly accelerated, and even the target rotation speed cannot be reached.
In order to further ensure that the rotational speed of the second wind wheel 16 can reach the target rotational speed, in the process of adjusting the rotational speed of the first wind wheel 14 and the rotational speed of the second wind wheel 16 to the target rotational speed, the adjusting speed of the rotational speed of the second wind wheel 16 leads the adjusting speed of the rotational speed of the first wind wheel 14, so that the rotational speed of the second wind wheel 16 is greater than the rotational speed of the first wind wheel 14 in the adjusting process, the wind pressure of the second wind wheel 16 is smaller, and the rotational speed of the second wind wheel 16 and the rotational speed of the first wind wheel 14 can both reach the target rotational speed.
In one embodiment, the adjustment process may be divided into a plurality of phases performed in a time sequence, and each phase may correspond to a time range. The time ranges corresponding to the different phases may be the same or different. The starting 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 rotor 16 is greater than the rotational speed of the first rotor 14. In other embodiments, the rotational speed acceleration of the second wind wheel 16 may be greater than the rotational speed acceleration of the first wind wheel 14, such that the rotational speed of the second wind wheel 16 is adjusted at a speed that is ahead of the rotational speed of the first wind wheel 14.
In certain embodiments, the adjustment speed of the rotational speed of the second rotor 16 is synchronized with the adjustment speed of the rotational speed of the first rotor 14. In this way, it can be further ensured that the rotational speed of the second wind wheel 16 can reach the target rotational speed.
Specifically, in the process of adjusting the rotation speed of the first wind wheel 14 and the rotation speed of the second wind wheel 16 to the target rotation speed, if the rotation speed of the first wind wheel 14 is greater than the rotation speed of the second wind wheel 16, the wind pressure of the second wind wheel 16 is caused to be greater, so that the second wind wheel 16 is slowly accelerated, and even the target rotation speed cannot be reached.
In order to further ensure that the rotational speed of the second wind wheel 16 can reach the target rotational speed, in the process of adjusting the rotational speed of the first wind wheel 14 and the rotational speed of the second wind wheel 16 to the target rotational speed, the adjusting speed of the rotational speed of the second wind wheel 16 is synchronous with the adjusting speed of the rotational speed of the first wind wheel 14, so that the rotational speed of the second wind wheel 16 is basically equal to the rotational speed of the first wind wheel 14 in the adjusting process, the wind pressure of the second wind wheel 16 is smaller, and the rotational speed of the second wind wheel 16 and the rotational speed of the first wind wheel 14 can reach the target rotational speed. The rotational speed of the second wind wheel 16 is substantially equal to the rotational speed of the first wind wheel 14, and it is understood that the rotational speed of the second wind wheel 16 is completely equal to the rotational speed of the first wind wheel 14, or the rotational speed difference between the two is within a preset range.
In one embodiment, the adjustment process may be divided into a plurality of phases performed in a time sequence, and each phase may correspond to a time range. The time ranges corresponding to the different phases may be the same or different. The starting 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 rotor 16 is substantially equal to the rotational speed of the first rotor 14. In other embodiments, the rotational speed acceleration of the second wind wheel 16 may be substantially equal to the rotational speed acceleration of the first wind wheel 14, such that the rotational speed of the second wind wheel 16 is synchronized with the rotational speed of the first wind wheel 14.

in case the rotational speed of the first wind wheel 14 is greater than the rotational speed of the second wind wheel 16, reducing the rotational speed of the first wind wheel 14 to the rotational speed of the second wind wheel 16;
In the case where the rotational speed of the first wind wheel 14 is not greater than the rotational speed of the second wind wheel 16, the rotational speeds of the first wind wheel 14 and the second wind wheel 16 are adjusted to the target rotational speeds.
