Control method of air conditioner and air conditioner

Technical Field

The embodiment of the invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof.

Background

At present, cold air can blow to a human body when an air conditioner refrigerates or dehumidifies, so that the human body is uncomfortable. The specification in national standard 33658: the higher the speed of the cooling air blown to the human body and the lower the temperature, the higher the blowing sensation index and the lower the evaluation score.

And specified in national standard 7725: when the air conditioner is used for refrigeration, the air deflector is required to be arranged at the position most prone to condensation according to the specified condensation working condition, condensation cannot drop on the outer surface of the indoor unit after the air conditioner is operated for 4 hours, and indoor air supply cannot have water drops. Therefore, in order to meet the national standard requirement, the included angle between the upper limit position of the air deflector of the air conditioner and the closed air deflector is set to be larger. However, the large included angle makes the cooling air supply easily blow to the human body, resulting in discomfort to the human body.

In order to enable the condensation to meet the national standard requirement, the evaporation temperature can be improved by controlling the maximum operation frequency under the condensation working condition to be lower in the prior art, so that the condensation on the outer surface of the indoor unit is reduced, but the refrigeration effect of the air conditioner can be seriously reduced. Therefore, how to improve the comfort of the user and make the condensation meet the national standard requirement without reducing the cooling effect of the air conditioner when the air conditioner is cooling has become an important research topic of those skilled in the art.

Each of these processors may be a Single-core processor (Single-CPU) or a Multi-core processor (Multi-CPU).

In order to improve the comfort level of a user, enable condensation to meet national standard requirements and not reduce the refrigeration effect of the air conditioner, the embodiment of the invention provides a control method of the air conditioner. As shown in fig. 2, the method may include:

201. and receiving a no-wind instruction of a user when the refrigeration mode or the dehumidification mode is operated.

When the air conditioner runs in a refrigeration mode or a dehumidification mode, a user can start the non-wind-feeling or direct-blowing-preventing function of the air conditioner through a wire controller, a remote controller, a control panel or intelligent application, and therefore the air conditioner can receive a non-wind-feeling instruction of the user.

202. And after the operation is carried out for a preset time period, the indoor temperature, the evaporation temperature and the relative humidity in the current period are obtained.

After receiving the no-wind instruction, the air conditioner may first determine whether the operation time of the cooling mode or the dehumidifying mode reaches a preset time period. If not, the outer air deflector is rotated to the position of the maximum upper limit included angle (namely, a prestored third preset angle which is smaller than the lower limit included angle and is used for prompting the user that the no-wind-sensing function is started), and the inner air deflector is rotated to the corresponding position to avoid condensation. When the operation time reaches the preset time period, the performance of the air conditioner is stable, so that the included angle of the two air guide plates can be periodically adjusted, and if the operation time reaches the preset time period, the included angle of the two air guide plates can be directly and periodically adjusted, and a cycle is taken as an example for description. The air conditioner may first acquire an indoor temperature, an evaporation temperature (evaporation temperature refers to a temperature at which the liquid is vaporized), and a relative humidity in a current period. Wherein, the evaporation temperature can be obtained by a temperature sensor arranged on the indoor coil.

203. And determining the corresponding dew point temperature according to the indoor temperature and the relative humidity.

After the air conditioner acquires the indoor temperature and the relative humidity in the current period, the air conditioner can search the corresponding relation among the prestored indoor temperature, the prestored relative humidity and the dew point temperature, and determine the corresponding dew point temperature (the dew point temperature refers to the temperature when water vapor in the air becomes dew).

For example, table 1 shows the correspondence among the indoor temperature, the relative humidity, and the dew point temperature, and as shown in table 1, the first row shows the value of the indoor temperature in degrees celsius, the first column shows the value of the relative humidity in degrees celsius, and the middle shows the value of the dew point temperature in degrees celsius. As can be seen from table 1, the dew point temperature increases as the relative humidity increases at the same indoor temperature. The higher the indoor temperature, the higher the dew point temperature at the same relative humidity.

								30	1	2	3	4	5	6	7

204. According to the difference value of the dew point temperature and the evaporation temperature, a first included angle between a first upper limit position and a first zero-degree position of the outer air deflector is determined, and a second included angle between a second upper limit position and a second zero-degree position of the inner air deflector is determined.

As shown in fig. 3, the inner air guiding plate is located inside the air outlet and surrounded by cold air, no temperature difference exists between the inner side and the outer side of the inner air guiding plate, condensation cannot occur, the outer air guiding plate is located outside the air outlet, and temperature difference exists between the inner side and the outer side of the outer air guiding plate, so that condensation is easy to occur. When the relative humidity of the indoor environment is higher, the corresponding dew point temperature is higher, the difference between the dew point temperature and the evaporation temperature is larger, and the condensation is more easily generated on the outer surface of the indoor unit. Under the same condition, the larger the included angle between the outer air deflector and the zero position is, the more difficult condensation is to be generated, so that in order to meet the national standard requirement of condensation, the larger the first included angle when the difference between the dew point temperature and the evaporation temperature is larger, the smaller the first included angle when the difference is smaller can be set. The first angle obtained by the experiment in advance is in positive correlation with the difference, as shown in fig. 4. According to the relationship shown in fig. 4, the first included angle and the difference value can be associated in advance, the relationship between the first included angle and the difference value is prestored in the air conditioner, and the upper limit included angle, which can swing by the inner air deflector, namely the relationship between the second included angle and the difference value is prestored in the air conditioner by combining the assistance effect of the inner air deflector. Thus, after the air conditioner determines the dew point temperature in the current period, the air conditioner can calculate the difference between the dew point temperature and the evaporation temperature obtained in step 202, and according to the pre-stored relationship, determine a first included angle between a first upper limit position where the outer air deflector can swing and a first zero-degree position, and determine a second included angle between a second upper limit position where the inner air deflector can swing and a second zero-degree position. The first zero-degree position is the position when the outer air guide plate is completely closed, and the second zero-degree position is the position when the inner air guide plate is completely closed.

Specifically, the method comprises the following steps: if the difference is smaller than or equal to the first preset temperature, the pre-stored first preset angle is determined as a first included angle, the pre-stored second preset angle is determined as a second included angle, at the moment, the difference is smaller, therefore, the first preset angle is smaller, the outer air deflector is positioned at the first preset angle and cannot blow to the human body and generate condensation, and the corresponding inner air deflector is positioned at the second preset angle and can be positioned at the position with the largest air outlet quantity. And if the difference is greater than or equal to the second preset temperature, determining a prestored third preset angle as a first included angle, and determining a prestored fourth preset angle as a second included angle, wherein the difference is greater, and the third preset angle is greater than the first preset angle and less than the lower limit included angle so as to avoid condensation. And because the third predetermines angle department and compares with first predetermined angle department, the people is blown to outer aviation baffle is changeed, consequently sets up the fourth predetermined angle and is less than the second predetermined angle, has raised the air-out height in certain procedure, though the air output reduces, but can reduce the cold wind that blows the human body. And if the difference value is greater than the first preset temperature and less than the second preset temperature, determining any angle in the range of the first preset angle and the third preset angle as a first included angle, and determining a second included angle according to the first included angle.

In one possible implementation, if the difference is largeWhen the first preset temperature is lower than the second preset temperature, the air conditioner may adopt the formula:

determining a first included angle A; the temperature sensor comprises a temperature sensor, a power supply, a battery. Of course, for other formulas, if the following condition is satisfied: as the difference decreases, the first included angle also decreases; when the range of the difference is between the first preset temperature and the second preset temperature, the first included angle obtained by using the formula is between the first preset angle and the third preset angle, and then the formula is also within the protection range of the embodiment of the invention. Correspondingly, the process that the air conditioner determines the second included angle according to the first included angle is as follows: if the first included angle is smaller than or equal to a fifth preset angle and larger than the first preset angle, determining a second preset angle as a second included angle; and if the first included angle is larger than the fifth preset angle and smaller than the third preset angle, determining the fourth preset angle as the second included angle. The first preset angle is larger than the fifth preset angle and smaller than the third preset angle and smaller than the lower limit included angle which can be swung by the outer air deflector; the upper limit included angle and the lower limit included angle of the inner air deflector are related to the specific box framework of the indoor unit.

It should be noted that fig. 5 is a schematic view of a lower envelope of the outlet air when the outer air guide plate is at different positions, where a first predetermined angle (where the outlet air is inclined upward along a tangential direction of an inner surface of the outer air guide plate, and the outlet air has a certain loss) corresponds to the lower envelope 1, and a lower limit angle (where the outlet air has a minimum loss and is least prone to generating condensation) corresponds to the lower envelope 2. As can be seen from fig. 5, the smaller the included angle between the outer air deflector and the first zero-degree position is, the higher the position of the lower envelope line is, the smaller the chance of blowing to the human body is at this time, and according to the test, the position corresponding to the first preset angle is obtained, and any position of the lower envelope line is higher than 1.8 meters, so that cold air cannot blow to the human body.

205. If the first included angle is smaller than the included angle of the outer air deflector in the previous period, the outer air deflector is controlled to rotate to the first upper limit position in the current period, and the inner air deflector is controlled to rotate to the second upper limit position.

After the first included angle and the second included angle are determined, the air conditioner can compare the first included angle with the included angle of the external air deflectors in the previous period. If the current period is the same as the preset period, the positions of the outer air guide plate and the inner air guide plate are controlled to be kept unchanged in the current period, and the indoor temperature, the evaporation temperature and the relative humidity are obtained again after the preset time period. If the first included angle is smaller than the included angle of the outer air deflector in the previous period, the air conditioner can control the outer air deflector to rotate to the first upper limit position in the current period, control the inner air deflector to rotate to the second upper limit position, and after the outer air deflector rotates to the first upper limit position for a preset time period, the first included angle and the second included angle are determined again until the first included angle is the first preset angle. Therefore, the indoor temperature, the evaporation temperature and the relative humidity are periodically acquired, the dew point temperature is determined according to the indoor temperature and the relative humidity, the included angle of the double air guide plates is dynamically adjusted according to the difference value of the dew point temperature and the evaporation temperature until the upper limit included angle of the outer air guide plates is the minimum, and the human body cannot be blown at the moment.

As an example, it is assumed that the first preset temperature T1 is 7 °, the first preset angle a1 is 20 °, the second preset angle is 95 °, the second preset temperature T2 is 12 °, the third preset angle A3 is 45 °, the fourth preset angle is 75 °, and the fifth preset angle is 35 °. Then, after receiving the no-wind instruction, assuming that the operation time of the cooling mode or the dehumidifying mode has reached the preset time period, at which the dew point temperature is 24 ℃, the evaporating temperature is 12 ℃, and the difference is 12 ℃, the outer air deflector is turned to the 45 ° position, and the inner air deflector is turned to the 75 ° position, as shown in fig. 6. After 10 minutes, the dew point temperature is newly determined to be 23 ℃, the evaporation temperature is 13 ℃, the difference is 10 ℃, the first included angle is equal to a fifth preset angle, the first included angle is A, 20+ (45-20) x (10-7)/(12-7) is 35 degrees, the first included angle is determined to be 95 degrees, the outer air deflector is rotated to the position of 35 degrees, and the inner air deflector is rotated to the position of 95 degrees, as shown in fig. 7. After 10 minutes, assuming a difference of 7 ℃, the outer air deflection plate is turned to the 20 ° position and the inner air deflection plate is kept at 95 ° as shown in fig. 8.
