Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
when air humidity is great, the air conditioner is under the refrigeration mode, when setting up to low wind speed operation, when beating the aviation baffle to the top or minimum extreme angle simultaneously, because the angle problem, the air conditioner air-out is not smooth, has cold wind dead zone, causes aviation baffle back and wind channel lower limb to extremely easily form the condensation water and drip, and the travelling comfort is poor, influences user experience.
the invention provides a control method and device for preventing condensation of an air conditioner, which can effectively avoid the formation and dripping of condensation and improve the comfort of the air conditioner and the user experience.
Fig. 1 is a schematic diagram illustrating a condensation forming principle of an air conditioner according to an embodiment of the present invention, wherein the condensation forming process is a saturated air cooling and moisture condensing process. Under the condition of keeping the water vapor content in the air unchanged, the temperature of the air is reduced isobarically, when the temperature is reduced to a certain value, the partial pressure of the water vapor reaches the saturation pressure corresponding to the current air humidity, at the moment, the water vapor in the air reaches saturation, and the corresponding temperature is the dew point temperature. If the temperature is further lowered, water in the air can precipitate in the form of condensation.
as shown in fig. 1, t1 represents the initial temperature of the humid air, P1 represents the partial pressure of water vapor corresponding to the humid air, t2 represents the saturation temperature corresponding to the humid air, and point a represents the initial point of the humid air. The wet air is in an unsaturated state at the moment, the partial pressure of water vapor is P1, P1 is kept unchanged along with the reduction of the temperature, and when the temperature is reduced to t2, the isobaric line P1 and the isotherm t2 intersect with the saturation curve at a point B. The wet air represented by point B is saturated wet air, and the temperature t2 of the saturated wet air is the dew point temperature. The temperature of the saturated humid air is continuously reduced to t3, as shown in the figure, an isotherm t3 intersects the saturated humid air line at a point C, the corresponding partial pressure of the water vapor is P3, and in the process of temperature reduction, along with the reduction of the partial pressure of the water vapor, the excessive water vapor is changed into condensed water in a condensation mode to be precipitated.
Therefore, when the air humidity is high, the temperature of the air around the air outlet continuously decreases along with the refrigeration of the air conditioner. If the air guide plate is set to operate at a low wind gear and is arranged at a limit angle, condensed water is easy to precipitate and drip around the air guide plate and the air outlet due to the angle.
FIG. 2 is a schematic diagram illustrating a method for controlling condensation prevention of an air conditioner according to an embodiment of the present invention, including steps S11-S13.
In step S11, the set temperature, the operating damper, and the air deflector angle are obtained when the air conditioner is operating in the cooling mode. When the air conditioner runs in a refrigeration mode, condensation is easy to form and separate out due to the fact that the temperature of blown cold air is low and the temperature difference between the blown cold air and the ambient environment is large. If the air conditioner operates in the heating mode, because warm air is blown out, and condensation is not easily formed around the air deflector and the air outlet, in the embodiment of the invention, the air conditioner is firstly confirmed to operate in the cooling mode, and then subsequent detection and control are carried out, so that the control reliability can be ensured, and unnecessary energy consumption can be saved.
FIG. 3 is a schematic view of an air deflector angle of the air conditioner according to the embodiment of the present invention, wherein the air deflector is at a position a and a position e, which are extreme angles; when the air deflector is in the c position, the direction is horizontal (angle). The limit angle of the air deflector is different according to different air conditioner models. The positions a, b, c, d and e of the air deflector in the figure are preset by a user of the air conditioner, and the adjustable position of the air deflector is set by a remote controller. In the present embodiment, the angles between b and c and d and c are both in the range of 30 ° to 50 °, preferably 45 °. When the air conditioner is determined to operate in the refrigeration mode, the temperature, the operation windshield and the air deflector angle set by the user at the moment are acquired, judgment and corresponding operation are carried out according to the acquired information, and effective condensation prevention control is achieved.
In step S12, it is determined whether the anti-condensation control condition is satisfied according to the set temperature, the operating windshield, and the air deflector angle. In an embodiment of the present invention, the anti-condensation control conditions include: the set temperature is smaller than a preset temperature threshold value, the operation wind shield is a low wind shield, and the angle of the air deflector is a limit angle, and when the three conditions are met simultaneously, the anti-condensation control condition is met. Wherein the preset temperature threshold value ranges from 18 ℃ to 21 ℃, and is preferably 20 ℃. In the cooling mode, when the user sets the temperature to be lower than 20 ℃, the operation wind level is the low wind level, and the air deflector is arranged at the limit angles, namely the positions a and e shown in fig. 3, the anti-condensation control condition is satisfied.
In the embodiment of the invention, when the temperature set by the user is lower than 20 ℃, the temperature of cold air blown out by the refrigeration operation of the air conditioner is lower, and when the air conditioner is operated in a low wind gear, the air flowing speed is lower. When the air deflector is arranged at a limit angle, condensed water is more easily formed to drip on the edge of the air deflector due to the fact that the inclined angle of the air deflector is larger. Therefore when satisfying above-mentioned three condition, judge for satisfying and prevent condensation control condition, the air conditioner is in the running state that forms the condensation most easily, needs in time to prevent condensation control this moment, can effectively avoid the condensation to form, promotes user experience.
In step S13, if the anti-condensation control condition is satisfied, entering an anti-condensation control stage, and controlling and adjusting the angle of the air deflector and the rotating speed of the inner fan, including: controlling and adjusting the angle of the air deflector to reduce a preset adjustment angle from the limit angle to the horizontal direction; and controlling the rotating speed of the inner fan to increase the preset adjusting rotating speed.
In the embodiment of the invention, when the anti-condensation control condition is judged to be met, the condition that the air conditioner is easy to generate condensation at the moment is indicated, and the anti-condensation control needs to be carried out in time. At this time, the angle of the air deflector is controlled and adjusted, and the preset adjustment angle is reduced from the limit angle of the position a or e to the horizontal direction (namely the position c), namely the included angle between the limit angle and the horizontal direction is reduced and reduced, and the preset adjustment angle is reduced. The value range of the preset adjusting angle is 5-15 degrees, preferably 10 degrees, namely the included angle between the position a and the position a 'and the included angle between the position e and the position e' are both 10 degrees. The rotation speed of the inner fan is controlled to increase the preset adjustment rotation speed, so that the air flow speed can be effectively increased, the temperature field around the air outlet is improved, the temperature difference between the air outlet and the ambient temperature is reduced, the air outlet quantity is ensured, the air outlet temperature is increased, and condensate water is prevented from being produced. The preset adjusting rotating speed ranges from 40rps to 60rps, and preferably ranges from 50 rps.
In the embodiment of the invention, when the anti-condensation control condition is judged to be met, the centering of the left and right wind sweeping blades is controlled and adjusted, and the opening degree of the electronic expansion valve is controlled to increase by the preset adjusting opening degree, wherein the value range of the preset adjusting opening degree is 40B-60B, and preferably 50B. When the left and right wind sweeping blades are controlled to be placed in the middle, the left and right wind sweeping blades rotate to the placed in the middle through the wind sweeping connecting rod through the stepping motor, and the air outlet volume and the air outlet smoothness are guaranteed. And the opening of the electronic expansion valve is controlled to be increased by 50B so as to reduce throttling and increase the flow of the refrigerant, and the air outlet temperature is increased so as to reduce the generation of condensed water.
In the embodiment of the invention, when the anti-condensation control condition is not met, the anti-condensation control stage is exited and the operation is carried out according to the mode actually set by the user. Namely, when the temperature set by the user is more than 20 ℃ or other wind gears are switched or the angle of the air deflector is switched (namely the position is not set as a position a or e), the anti-condensation control is quitted, and the operation is carried out according to the specific mode actually set by the user.
In the embodiment of the invention, when the air conditioner is detected to switch the operation mode, the operation time of the compressor exceeds the preset time or the air conditioner detects any fault shutdown, the condensation prevention control stage is exited, and the air conditioner is operated according to the mode actually set by a user. When a user sets the air conditioner to be switched to other modes from the cooling mode, such as the heating mode or other operation modes, the air conditioner automatically exits the condensation prevention control stage, different setting requirements of the user can be better met, and the comfort of the air conditioner is improved.
The invention judges whether to enter the condensation prevention control stage according to the set temperature, the operation wind shield and the angle of the air deflector, judges and controls according to the existing structure of the air conditioner and the formation principle of condensed water, can ensure the clearance between the air door and the air duct by adjusting the angle of the air deflector and the left and right wind sweeping angles under specific conditions, and also improves the air outlet speed by increasing the rotating speed of the inner fan and the opening degree of the electronic expansion valve, thereby preventing the generation of the condensation water and effectively improving the condensation prevention effect.
