In the embodiment of the disclosure, the indoor fan of the air conditioner is an axial flow fan, the airflow of the axial flow fan is in the same direction as the axis of the fan blade, and the air flows in parallel to the axis of the fan. The axial flow fan can release certain heat in the reverse rotation process, so that the temperature of the surrounding environment is properly increased.
Referring to fig. 1, an embodiment of the present disclosure provides a control method for preventing condensation of an air conditioner, including the following steps:
and S101, acquiring the ambient temperature of an air deflector of the air conditioner and the temperature of the air deflector under the condition of air conditioner refrigeration operation.
The air conditioner is characterized in that temperature sensors are respectively arranged at the position of the air conditioner close to the air deflector and on the air deflector of the air conditioner, and are used for detecting the ambient temperature at the air deflector and the temperature of the air deflector (namely the temperature of a panel of the air deflector).
S102, under the condition that the ambient temperature is higher than the temperature of the air deflector, controlling the indoor fan of the air conditioner to reversely rotate so as to reduce the condensation degree of the air deflector.
Optionally, when the ambient temperature is greater than the temperature of the air deflector, controlling the indoor fan of the air conditioner to rotate reversely to reduce the degree of condensation of the air deflector includes: obtaining the temperature difference between the ambient temperature and the temperature of the air deflector; under the condition that the temperature difference value is greater than or equal to a first preset temperature difference value and smaller than a second preset temperature difference value, after the indoor fan is controlled to normally operate for a first time period, the indoor fan is controlled to reversely operate for a second time period; controlling the indoor fan to reversely rotate for a third time period under the condition that the temperature difference value is greater than a second preset temperature difference value; the first preset temperature difference value is smaller than the second preset temperature difference value, the first duration is longer than the second duration, and the second duration is longer than the third duration.
The first predetermined temperature difference is in the range of [2 ℃, 5 ℃ C ], e.g., 2 ℃, 3 ℃, 4 ℃, 5 ℃ C, and the second predetermined temperature difference is in the range of [6 ℃, 9 ℃ C ], e.g., 6 ℃, 7 ℃, 8 ℃, 9 ℃ C. The first time period is [20min, 30min ], e.g., 20min (min), 25min, 30min, the second time period is [4min, 6min ], e.g., 4min, 5min, 6min, and the third time period is [1min, 3min ], e.g., 1min, 2min, 3 min. When the temperature difference value between the ambient temperature and the air deflector temperature is between a first preset temperature difference value and a second preset temperature difference value, firstly controlling the indoor fan to normally operate for a first time period to form a relatively stable laminar flow, and then controlling the indoor fan to reversely operate for a second time period to cause airflow torsion, so that the moisture of the air deflector can be taken away, and the possibility of water drops formed by condensation of the air deflector; when the temperature difference between the ambient temperature and the air deflector temperature is greater than the second preset temperature difference, the indoor ambient temperature is higher, the water drops can be well evaporated only by controlling the indoor fan to reversely rotate for the second time, and the air deflector is prevented from being condensed to form water drops and dropping.
Optionally, the reversal duration of the indoor fan and the temperature difference between the ambient temperature and the air deflector temperature satisfy the following relationship:
where t is the inversion duration, t0Presetting inversion time length, delta T is an inversion time length compensation value, delta T is a temperature difference value between ambient temperature and air deflector temperature, and delta T0Is a preset temperature difference value.
Under the condition that the ambient temperature is higher than the temperature of the air deflector, the larger the temperature difference between the ambient temperature and the temperature of the air deflector, the more easily condensation is formed on the air deflector of the air conditioner, but the shorter the time required by the indoor fan for reversely rotating to evaporate water drops is. Therefore, the length of the reversal of the indoor fan is determined according to the relationship between the length of the reversal of the indoor fan and the temperature difference value, condensation of the air deflector can be well avoided to form water drops, and meanwhile, the indoor fan is prevented from being damaged due to the fact that the indoor fan runs reversely under the high-temperature environment for a long time.
By adopting the control method for preventing condensation of the air conditioner, provided by the embodiment of the disclosure, under the condition of refrigeration operation of the air conditioner, the ambient temperature of the air deflector of the air conditioner and the air deflector temperature of the air deflector are obtained, and under the condition that the ambient temperature is higher than the air deflector temperature, the indoor fan of the air conditioner is controlled to rotate reversely so as to reduce the condensation degree of the air deflector. Like this, under the circumstances that ambient temperature is greater than the aviation baffle temperature, under the easy environmental condition who condenses of aviation baffle promptly, utilize the indoor fan reversal characteristics that generate heat, the reversal of control indoor fan reduces the ambient humidity near the aviation baffle to accelerate volatilizing of aviation baffle department condensation, can avoid the problem that air conditioner aviation baffle condensation formed the water droplet and drips better, need not to increase extra air conditioner part, the cost is lower.
In some embodiments, controlling indoor fan reversal of an air conditioner includes: obtaining the environment humidity at the air deflector and the running frequency of a compressor of the air conditioner; determining the reverse rotation speed of the indoor fan according to the humidity of the environment humidity and the frequency of the operation frequency; and controlling the indoor fan to rotate reversely according to the reverse rotation speed.
Because the condensation on the air deflector is mainly formed by utilizing the moisture in the environment near the air deflector, the condensation degree of the air deflector is easily influenced by the environment humidity at the air deflector; the operating frequency of the air conditioner compressor determines the refrigeration degree of the air conditioner, and indirectly influences the temperature of the air deflector plate, so that the condensation degree of the air deflector is influenced. Therefore, the reverse rotation speed of the indoor fan is determined together comprehensively according to the environment humidity at the air deflector and the running frequency of the compressor of the air conditioner, and the condensation prevention effect of the air conditioner can be better realized.
Optionally, determining a reverse rotation speed of the indoor fan according to the humidity of the ambient humidity and the frequency of the operating frequency includes: determining the reverse rotation speed as a first rotation speed under the conditions that the environment humidity is greater than or equal to the preset humidity and the operation frequency is greater than the first operation frequency or less than the second operation frequency; determining the reverse rotation speed as a second rotation speed under the conditions that the environment humidity is greater than or equal to the preset humidity, and the operation frequency is greater than or equal to a second frequency and less than or equal to a first operation frequency; determining the reverse rotation speed as a third rotation speed under the condition that the environmental humidity is less than the preset humidity; the first operating frequency is greater than the second operating frequency, the first rotating speed is greater than the second rotating speed, and the second rotating speed is greater than the third rotating speed.
Optionally, the preset humidity is in a range of [ 55%, 65% ], for example, 55%, 60%, 65%, the first operating frequency is in a range of [0.8F, F ], for example, 0.8F, 0.9F, F ], the second operating frequency is in a range of [0.4F, 0.6F ], for example, 0.4F, 0.5F, 0.6F, the first rotational speed is in a range of [0.8R, R ], for example, 0.8R, 0.9R, R, the second rotational speed is in a range of [0.5R, 0.7R ], for example, 0.5R, 0.6R, 0.7R, and the third rotational speed is in a range of [0.2R, 0.4R ], for example, 0.2R, 0.3R, 0.4R. Here, F is the maximum operation frequency allowed by the air conditioner compressor, and R is the maximum reverse rotation speed allowed by the indoor fan of the air conditioner.
When the environment humidity is greater than or equal to the preset humidity and the operation frequency of the compressor is greater than the first operation frequency, the room is in high-load heat exchange, the heat exchange between the indoor humidity and the environment temperature is always relatively high in load, and the indoor fan rotates reversely at a high speed; when the environment humidity is greater than or equal to the preset humidity and the operation frequency of the compressor is less than the second operation frequency, the indoor fan rotates reversely at a high speed, and the dew removing effect can be achieved after the indoor fan operates for a short time; when the environmental humidity is greater than or equal to the preset humidity and the operating frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the indoor fan keeps medium-speed reversal, and a good condensation preventing effect can be achieved; when the environment humidity is less than the preset humidity, the moisture content at the air deflector is low, the condensation generating condition is poor, and the indoor fan can achieve a good condensation preventing effect by low-speed reversal.
In some embodiments, controlling indoor fan reversal of an air conditioner includes: obtaining the environmental humidity and the environmental pressure at the air deflector and the running frequency of a compressor of the air conditioner; determining the reverse rotation speed of the indoor fan according to the humidity of the environment humidity, the pressure of the environment pressure and the frequency of the operation frequency; and controlling the indoor fan to rotate reversely according to the reverse rotation speed.
Because the condensation on the air deflector is mainly formed by utilizing the moisture in the environment near the air deflector, the condensation degree of the air deflector is easily influenced by the environment humidity at the air deflector; moreover, moisture in the air is easy to be condensed to form condensation in a low-pressure environment; the operating frequency of the air conditioner compressor determines the refrigeration degree of the air conditioner, and indirectly influences the temperature of the air deflector plate, so that the condensation degree of the air deflector is influenced. Therefore, the reverse rotation speed of the indoor fan is determined together comprehensively according to the environment humidity and the environment pressure at the air deflector and the operation frequency of the compressor of the air conditioner, and the condensation prevention effect of the air conditioner can be better realized.
Optionally, determining a reverse rotation speed of the indoor fan according to the humidity of the ambient humidity, the pressure of the ambient pressure, and the frequency of the operating frequency, including: determining the reverse rotation speed as a first rotation speed under the conditions that the environment humidity is greater than or equal to the preset humidity, the environment pressure is less than or equal to the preset pressure, and the operation frequency is greater than the first operation frequency or less than the second operation frequency; determining the reverse rotation speed as a second rotation speed under the conditions that the environment humidity is greater than or equal to the preset humidity, the environment pressure is less than or equal to the preset pressure, and the operation frequency is greater than or equal to a second frequency and less than or equal to a first operation frequency; determining the reverse rotation speed as a second rotation speed under the condition that the environment humidity is less than the preset humidity and the environment pressure is less than or equal to the preset pressure; determining the reverse rotation speed as a third rotation speed under the condition that the environment humidity is less than the preset humidity and the environment pressure is greater than the preset pressure; the first operating frequency is greater than the second operating frequency, the first rotating speed is greater than the second rotating speed, and the second rotating speed is greater than the third rotating speed.
Optionally, the preset pressure is in a range of [1020hPa, 1060hPa ], for example, 1020hPa, 1040hPa, 1060 hPa. When the environment humidity is greater than or equal to the preset humidity, the environment pressure is less than or equal to the preset pressure, and the operation frequency of the compressor is greater than the first operation frequency, the room is in high-load heat exchange, the heat exchange between the indoor humidity and the environment temperature is always relatively high in load, and the indoor fan rotates reversely at a high speed; when the environment humidity is greater than or equal to the preset humidity, the environment pressure is less than or equal to the preset pressure, and the operation frequency of the compressor is less than the second operation frequency, the indoor fan rotates reversely at a high speed, and the dew removing effect can be achieved after the indoor fan operates for a short time; when the environment humidity is greater than or equal to the preset humidity, the environment pressure is less than or equal to the preset pressure, and the operating frequency is greater than or equal to the second frequency and less than or equal to the first operating frequency, the indoor fan keeps medium-speed reversal, and a good condensation prevention effect can be achieved; when the environmental humidity is less than the preset humidity and the environmental pressure is less than or equal to the preset pressure, the indoor fan keeps medium-speed reversal, so that a better condensation prevention effect can be achieved; when the environment humidity is less than the preset humidity and the environment pressure is greater than the preset pressure, the moisture content at the air deflector is low, the environment pressure is high, the generation condition of condensation is poor, and the indoor fan can achieve a good condensation prevention effect by low-speed reversal.
In some embodiments, the control method for preventing condensation of the air conditioner further includes: obtaining a current angle and a target angle of the air deflector; and in the process of reversing the indoor fan, controlling the air deflector to rotate based on the current angle and the target angle.
The target angle of the air deflector is an angle at which the air deflector is not easy to accumulate water drops, for example, an included angle of 60 degrees is formed between the plane of the air deflector and the horizontal plane.
Optionally, controlling the air deflector to rotate based on the current angle and the target angle, including: calculating a rotation angle of the air deflector based on the current angle and the target angle; and controlling the air deflector to rotate according to the rotation angle so as to overturn the air deflector to a target angle.
For example, the included angle between the plane of the current air deflector and the horizontal plane is 20 degrees, the rotation angle of the air deflector is 40 degrees based on the current angle and the target angle, and the air deflector is controlled to rotate 40 degrees to turn over to form a 60-degree included angle with the horizontal plane in the process of reversing the indoor fan.
In the embodiment of the disclosure, the current angle and the target angle of the air deflector are obtained, the air deflector is controlled to rotate in the reversing process of the indoor fan, so that the air deflector is turned to the target angle at which water drops are not easy to accumulate, the probability of water drops condensation at the air deflector is reduced, meanwhile, the contact area of the air deflector and the air flow blown out by the indoor fan is increased, the volatilization of condensation at the air deflector is accelerated, and the risk of water drops formed by condensation of the air deflector of the air conditioner can be effectively reduced.
