Based on the hardware structure, various embodiments of the outdoor fan control method are provided.
The invention provides an outdoor fan control method.
Referring to fig. 2, fig. 2 is a schematic flowchart of an outdoor fan control method according to a first embodiment of the present invention.
In this embodiment, the method for controlling an outdoor fan is applied to an air conditioner, the air conditioner includes a dual wind wheel outdoor fan, the dual wind wheels in the dual wind wheel outdoor fan are axial flow wind wheels, the dual wind wheels are selectively and symmetrically arranged on a motor rotating shaft of an indoor fan, and are used for accelerating heat exchange between an outdoor heat exchanger and air, and the method for controlling the outdoor fan includes:
step S10, when the air conditioner is in a refrigeration running state, detecting the outdoor environment temperature and the outdoor condenser temperature;
in the present embodiment, when the air conditioner is in the cooling operation state, the outdoor ambient temperature and the outdoor condenser temperature are detected. The air conditioner can be provided with an operation detection module, and the operation state of the air conditioner can be detected through the operation detection module; the air conditioner can also be provided with a temperature detection module, and the outdoor ambient temperature and the outdoor condenser temperature can be respectively detected through the temperature detection module. It should be noted that the operation detection module may determine the operation state of the air conditioner according to the current state of the four-way valve, for example, when the current state of the four-way valve is on, it may determine that the air conditioner is in a heating operation state, and when the current state of the four-way valve is off, it may determine that the air conditioner is in a cooling operation state. It can be understood that, in this embodiment, the operation detection module may also determine the operation state of the air conditioner according to other manners, and is not limited to the manner of determining the operation state of the air conditioner through the current state of the four-way valve, which is not described herein in detail.
Specifically, when the air conditioner starts, the air conditioner triggers the operation detection module, when the operation detection module detects that the air conditioner is in a refrigeration operation state, the air conditioner starts the temperature detection module, the temperature detection module detects through the outdoor environment temperature sensor to obtain the outdoor environment temperature, and meanwhile, the temperature detection module detects through the outdoor condenser temperature sensor to obtain the outdoor condenser temperature. It should be noted that the outdoor temperature sensor is usually disposed on the outdoor heat exchanger, and it is understood that, in this embodiment, the outdoor temperature sensor may also be disposed in other areas, which is not limited herein. And the outdoor condenser temperature sensor can be arranged on the outdoor condenser coil pipe, the branch inlet or the branch outlet.
The working principle of the refrigeration operation state is that a low-temperature low-pressure refrigerant enters the compressor to be compressed and converted into high-temperature high-pressure refrigerant vapor, then enters the outdoor heat exchanger to exchange heat and be converted into low-temperature high-pressure refrigerant liquid, then the low-temperature high-pressure refrigerant liquid enters the throttling component to be converted into the low-temperature low-pressure refrigerant liquid, and after the indoor evaporator finishes heat absorption and refrigeration, the low-temperature high-pressure refrigerant liquid returns to the compressor to continuously repeat the refrigeration cycle.
Specifically, based on step S10, the step of detecting the outdoor ambient temperature and the outdoor condenser temperature includes:
step a11, detecting through an outdoor environment temperature sensor to obtain an outdoor environment temperature;
in this embodiment, the outdoor ambient temperature is obtained by detecting with an outdoor ambient temperature sensor. The outdoor temperature sensor is usually disposed on the outdoor heat exchanger, and it can be understood that, in this embodiment, the outdoor temperature sensor may also be disposed in other areas, which is not specifically limited herein; the outdoor ambient temperature is typically the temperature of the environment surrounding the outdoor heat exchanger.
And a12, detecting through an outdoor condenser temperature sensor to obtain the temperature of the outdoor condenser, wherein the outdoor condenser temperature sensor is arranged at the branch outlet of the outdoor condenser.
In this embodiment, the outdoor condenser temperature is obtained by detecting with an outdoor condenser temperature sensor, wherein the outdoor condenser temperature sensor is disposed at the branch outlet of the outdoor condenser. The outdoor condenser temperature sensor is arranged at the branch outlet of the outdoor condenser, so that the detected outdoor condenser temperature is the temperature of the outdoor condenser after complete heat exchange.
Specifically, step a12 includes:
step a121, detecting by a plurality of outdoor condenser temperature sensors to obtain a plurality of outdoor condenser branch outlet temperatures;
in this embodiment, the outdoor condenser temperature sensors include a plurality of outdoor condenser temperature sensors, and a plurality of outdoor condenser branch outlet temperatures are obtained by detecting the plurality of outdoor condenser temperature sensors. It can be appreciated that the more outdoor condenser branch outlet temperatures are detected, the more accurate the resulting outdoor condenser temperature.
And a122, performing average operation on the outlet temperatures of the multiple outdoor condenser branches, and taking the obtained average value as the outdoor condenser temperature.
And then, averaging the outlet temperatures of the branches of the outdoor condenser, and taking the average value as the temperature of the outdoor condenser. It can be understood that the outlet temperatures of the plurality of outdoor condenser branches usually have a small difference, and therefore, the outlet temperatures of the plurality of outdoor condenser branches are averaged, and the obtained average value is used as the outdoor condenser temperature more accurately. Of course, the outdoor condenser temperature can also be determined from the outlet temperatures of the plurality of outdoor condenser branches by a mathematical method such as median and mode.
Step S20, judging whether the outdoor environment temperature is smaller than a first preset threshold value or not;
in this embodiment, it is determined whether the outdoor ambient temperature is less than a first preset threshold. It should be noted that the rotating speed of the dual wind wheels in the outdoor fan of the air conditioner, that is, the rotating speed of the dual motors in the outdoor fan of the air conditioner, is usually adjusted according to the outdoor environment temperature. Specifically, when the outdoor environment temperature decreases, the rotation speed of the double wind wheels in the outdoor fan decreases, and when the outdoor environment temperature increases, the rotation speed of the double wind wheels in the outdoor fan increases, for example, when the outdoor environment temperature is 20 ℃ (celsius), the rotation speeds of the double wind wheels in the outdoor fan are both 900rpm (revolutions per minute), when the outdoor environment temperature is 18 ℃, the rotation speeds of the double wind wheels in the outdoor fan are 900rpm and 800rpm, respectively, and when the outdoor environment temperature is-5 ℃, the rotation speeds of the double wind wheels in the outdoor fan are 100rpm and 100rpm, respectively.
By the above example, it can be understood that when the outdoor environment temperature is reduced to a critical value, the rotation speeds of the two wind wheels in the outdoor fan cannot be reduced any more, and at this time, the two wind wheels in the outdoor fan need to be controlled to be turned on or turned off respectively, that is, the working states of the two wind wheels in the outdoor fan are controlled. Through the above description, those skilled in the art can understand that, when the threshold value of the outdoor environment temperature is taken as the first preset threshold value, determining whether the outdoor environment temperature is less than the first preset threshold value is equivalent to determining whether the dual wind wheels in the outdoor fan can also reduce the speed. The first preset threshold may be determined according to a mapping relationship between the preset outdoor environment temperature and the rotational speed of the dual wind wheels, and optionally is an outdoor environment temperature corresponding to a minimum value of the rotational speed of the dual wind wheels in the mapping relationship between the preset outdoor environment temperature and the rotational speed of the dual wind wheels. Of course, the first preset threshold may also be set in other manners, which are not described in detail herein. In addition, it is understood that the first preset threshold corresponding to different air conditioners may be set according to actual conditions, for example, the first preset threshold is-5 ℃, -4 ℃, -6 ℃, and the like, and is not limited herein.
In addition, it should be noted that the motor in the outdoor fan of the air conditioner is usually a direct current motor, so that the speed of the double wind wheels in the outdoor fan can be adjusted. Of course, the motor in the outdoor fan can also be an alternating current motor, and only a frequency converter is needed to change the power frequency.
Step S30, if the outdoor environment temperature is smaller than the first preset threshold, comparing the outdoor condenser temperature with a second preset threshold and a third preset threshold respectively;
in this embodiment, if the outdoor ambient temperature is less than the first preset threshold, the outdoor condenser temperature is compared with the second preset threshold and the third preset threshold, respectively. It can be understood that when the temperature of the outdoor condenser is too low, the evaporator of the air conditioner will be protected at low temperature, so that the compressor of the air conditioner is frequently started, and the refrigeration effect is affected. Therefore, the second preset threshold and the third preset threshold are obtained in the following manner: the method comprises the steps that the lowest rotating speed of double wind wheels in an outdoor fan is kept, the outdoor environment temperature is controlled to be reduced from a first preset threshold value, and in the process of reduction, if the low-temperature protection of an evaporator of an air conditioner is detected, the temperature of an outdoor condenser at the moment is used as a second preset threshold value; and then, controlling one wind wheel in the outdoor fan to stop, then controlling the outdoor environment temperature to drop, and taking the temperature of the outdoor condenser at the moment as a third preset threshold value when detecting that the evaporator of the air conditioner carries out low-temperature protection in the dropping process.
Of course, the second preset threshold and the third preset threshold may also be obtained by other methods, which are not described in detail herein. In addition, the second preset threshold and the third preset threshold are different according to the difference of the first preset threshold, for example, when the first preset threshold is-5 ℃, the second preset threshold may be 10 ℃, 9 ℃, 11 ℃, etc., and is not limited herein.
And S40, correspondingly controlling the working states of the double wind wheels in the double wind wheel outdoor fan according to the comparison result.
In this embodiment, according to the comparison result, the operating states of the dual wind wheels in the dual wind wheel outdoor fan are correspondingly controlled. And when the outdoor environment temperature is below a first preset threshold, controlling the working state of the double wind wheels in the outdoor fan according to the comparison result, namely according to the temperature of the outdoor condenser. For example, when the temperature of the outdoor condenser is too high, namely the temperature of the outdoor condenser is greater than a second preset threshold value, the double wind wheels are controlled to be in a running state, so that the circulation speed of air around the outdoor heat exchanger is increased, the heat of the outdoor heat exchanger is quickly dissipated, and the temperature of the outdoor condenser is reduced; when the temperature of the outdoor condenser is too low, namely the temperature of the outdoor condenser is less than or equal to a third preset threshold value, the double wind wheels are controlled to be in a stop state to reduce the circulation speed of air around the outdoor heat exchanger, so that the heat dissipation of the outdoor heat exchanger is slow, and the temperature of the outdoor condenser is ensured not to be too low.
The working state comprises a single wind wheel running state, a running state and a stopping state. And correspondingly controlling the working states of the double wind wheels in the double wind wheel outdoor fan according to the comparison result, namely respectively controlling the running or stopping of the double wind wheels. For example, when the operating state is a single wind wheel operating state, the double wind wheels are controlled to keep operating in a single wheel mode, and it can be understood that any one of the double wind wheels can be controlled to operate or stop operating, which is not specifically limited herein.
It should be noted that, when the working state of the wind wheel in the outdoor fan is the running state, if the wind wheel is already in the running state, the running state is maintained; and if the wind wheel is in a stop state, starting the wind wheel and operating at the lowest rotating speed of the wind wheel.
The embodiment of the invention provides an outdoor fan control method, which is applied to an air conditioner, wherein the air conditioner comprises a double-wind-wheel outdoor fan, and when the air conditioner is in a refrigerating running state, the outdoor environment temperature and the outdoor condenser temperature are detected; judging whether the outdoor environment temperature is smaller than a first preset threshold value or not; if the outdoor environment temperature is lower than the first preset threshold, comparing the outdoor condenser temperature with a second preset threshold and a third preset threshold; and correspondingly controlling the working states of the double wind wheels in the double wind wheel outdoor fan according to the comparison result. In the embodiment of the invention, when the outdoor environment temperature is less than the first preset threshold value, the low-temperature refrigeration cannot be realized by regulating the speed of the wind wheel in the outdoor fan, and the working state of the double wind wheels in the outdoor fan is correspondingly controlled according to the temperature of the outdoor condenser.
Further, based on the above-described first embodiment, a second embodiment of the outdoor fan control method of the present invention is proposed.
Referring to fig. 3, fig. 3 is a flowchart illustrating an outdoor fan control method according to a second embodiment of the present invention.
In this embodiment, the step S40 includes:
step S41, if the temperature of the outdoor condenser is less than or equal to the second preset threshold and greater than the third preset threshold, controlling the working state of a double wind wheel in the double wind wheel outdoor fan to be a single wind wheel running state;
in this embodiment, when the outdoor condenser temperature is neither too high nor too low, that is, the outdoor condenser temperature is less than or equal to the second preset threshold value and is greater than the third preset threshold value, the double wind wheels are controlled to be in a single wind wheel operation state.
Specifically, the double wind wheels in the outdoor fan are adjusted from the running state to the single wind wheel running state, so that the circulation speed of air around the outdoor heat exchanger is properly reduced, the heat dissipation of the outdoor heat exchanger is slow, and the temperature of an outdoor condenser is not too low; the double wind wheels in the outdoor fan are adjusted to be in a single wind wheel running state from a stop state, so that the circulation speed of air around the outdoor heat exchanger can be properly accelerated, the heat dissipation of the outdoor heat exchanger is faster, and the temperature of an outdoor condenser is not overhigh.
Specifically, step S41 includes:
step a411, if the outdoor condenser temperature is less than or equal to the second preset threshold and greater than the third preset threshold, obtaining the working state and the working duration of a first wind wheel and a second wind wheel in the double-wind-wheel outdoor fan;
in this embodiment, if the outdoor condenser temperature is less than or equal to the second preset threshold and greater than the third preset threshold, the working state and the working duration of the first wind wheel and the second wind wheel in the dual-wind-wheel outdoor fan are obtained.
