A control method of an air conditioner 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5, in which the air conditioner 100 has a first outlet port 1, the air conditioner 100 includes a counter-rotating fan 2 and an indoor heat exchanger 6, and the counter-rotating fan 2 blows air toward the first outlet port 1. The counter-rotating fan 2 comprises a first wind wheel 21 and a second wind wheel 22 which are oppositely arranged, and the first wind wheel 21 is arranged adjacent to the indoor heat exchanger 6. It is understood that the air conditioner 100 further includes a housing 4 provided with the first air outlet 1, and it is worth mentioning that the rotation directions of the blades of the first wind wheel 21 and the second wind wheel 22 are opposite, the first wind wheel 21 in the embodiment of the present invention may be an axial flow wind wheel or an oblique flow wind wheel, and the second wind wheel 22 may be an axial flow wind wheel or an oblique flow wind wheel, so that various types of counter-rotating fans 2 may be combined.
Wherein the rotation speed of the first wind wheel 21 is n1, the rotation speed of the second wind wheel 22 is n2, and the air conditioner 100 has a plurality of function modes, which include a no-wind mode and a wind mode.
It should be noted that the non-wind-sensing mode in the above description can be understood as follows: the set distance from the wall surface where the air conditioner 100 is installed may be, for example, 2.5m from the wall surface where the air conditioner 100 is installed, an indoor comfortable environment in which an average value of air flow velocity in a vertical plane parallel to the installation surface of the air conditioner 100 is 0.3m/s or less (including 0.3m/s) and a DR (drawing index) value is 5% or less. Where the DR value is used to quantitatively predict the percentage of dissatisfied persons caused by the sensation of blowing. The front side of the air conditioner 100 may be formed with a no-wind-feeling region, wherein the closest distance of the no-wind-feeling region to the air conditioner 100 is a no-wind-feeling distance.
In the no-wind mode, the front of the air conditioner 100 may include a wind-sensitive region, a no-wind region, and a no-wind region, which are sequentially distributed from the near to the far, where the wind-sensitive region is closest to the air conditioner 100, and the air flow speed in the region is high, so that the user feels strong blowing feeling and is likely to feel uncomfortable. The no-wind zone is farthest away from the air conditioner 100, where the air flow velocity is nearly zero and the user does not feel the wind at all. The no-wind feeling region is located between the no-wind feeling region and the blowing feeling region, the air flow speed in the region is relatively slow, the wind feeling felt by the user does not cause discomfort to the user, and the user can obviously feel the cooling or heating of the air conditioner 100, thus having high use comfort.
It is understood that the wind patterns can be understood as: the set distance from the wall surface where the air conditioner 100 is installed may be, for example, an indoor comfortable environment in which the average value of the air flow velocity in a vertical plane parallel to the installation surface of the air conditioner 100 is 0.3m/s or more and the DR (draft rating index) value is more than 5% at 2.5m from the wall surface where the air conditioner 100 is installed.
According to the air conditioner 100 of the embodiment of the present invention, the counter-rotating fan 2 including the first wind wheel 21 and the second wind wheel 22 is arranged in the casing 4, compared with the air conditioner in the related art that a centrifugal fan or a cross-flow fan is adopted, the rotating directions of the blades of the first wind wheel 21 and the second wind wheel 22 of the air conditioner 100 of the embodiment of the present invention are opposite, the first wind wheel 21 and the second wind wheel 22 are guide vanes in the air flowing direction, the tangential rotating speed of the air flow (i.e. from dynamic to static) is eliminated, the work efficiency of the counter-rotating fan 2 on the air is improved, and the air flow passing through the two wind wheels flows towards the air outlet, so as to realize the effect of long-distance air supply.
Secondly, the first wind wheel 21 and the second wind wheel 22 can expand the conveying range of cold air under the condition of different rotating speeds. Because when one wind wheel rotates at a higher rotating speed and the other wind wheel rotates at a lower rotating speed, the wind wheel with the higher rotating speed plays a leading role, and based on the wind dispersing effect of the axial flow wind wheel or the oblique flow wind wheel, the angle range of the cold wind flowing out from the first air outlet is larger, and the wide-angle air supply is realized. In addition, the rotating speeds of the first wind wheel 21 and the second wind wheel 22 can be adjusted according to needs based on the wind dispersing effect of the axial flow wind wheel or the oblique flow wind wheel, so that the wind dispersing effect is achieved, the wind can be supplied flexibly or without wind, and poor experience of a user caused by direct blowing of cold wind flowing out of the first air outlet 1 is avoided.
According to the control method of the air conditioner 100 of the embodiment of the present invention, the control method includes the steps of:
when the air conditioner 100 operates, the function mode selected by the air conditioner 100 is detected, and when the function mode is detected to be a no-wind-sense mode, the first wind wheel 21 and the second wind wheel 22 are controlled to meet the following conditions: when detecting that the function mode is the wind sensation mode, controlling the first wind wheel 21 and the second wind wheel 22 to meet the following requirements that n1 is (0.5-1.2) n 2: n1 is (0.5-2) n2, wherein the rotating speed n2 of the second wind wheel 22 in the no-wind-sensation mode is smaller than the rotating speed n2 of the second wind wheel 22 in the wind-sensation mode.
Specifically, under the functional working condition that the air conditioner 100 performs cooling or heating, when it is detected that the functional mode of the air conditioner 100 is the no-wind-sensation mode, the noise can be reduced on the premise of ensuring that the outlet air of the air conditioner 100 is the no-wind-sensation mode by controlling the space between the first wind wheel 21 and the second wind wheel 22 to satisfy n1 ═ 0.5-1.2) n 2. When the functional mode of the air conditioner 100 is detected to be the wind sensing mode, the requirement that n1 is (0.5-2) n2 is met by controlling the first wind wheel 21 and the second wind wheel 22, and therefore noise can be reduced on the premise that the wind outlet of the air conditioner 100 is guaranteed to be the wind sensing mode. Therefore, the purpose that the air conditioner 100 can be switched to the corresponding function mode can be achieved by detecting the function mode selected by the air conditioner 100 and controlling the rotating speed between the first wind wheel 21 and the second wind wheel 22, and the comfort of the room air conditioner 100 is further improved.
Therefore, according to the control method of the air conditioner 100 of the embodiment of the present invention, the air conditioner 100 has the advantages of convenient use, good user experience, and the like.
According to the control method of the air conditioner 100 provided by the embodiment of the invention, the purpose of changing the function mode of the air conditioner 100 is achieved by detecting the function mode selected by the air conditioner 100 and controlling the rotating speed between the first wind wheel 21 and the second wind wheel 22, so that the comfort of the room air conditioner 100 is improved.
In some embodiments of the present invention, the counter-rotating fan 2 may be a counter-rotating axial fan, and the counter-rotating fan 2 includes a motor, an impeller, an explosion-proof cover, a main machine air duct and a single-layer or multi-layer diffuser, wherein the explosion-proof cover is wrapped outside the motor, the main machine air duct is wrapped outside the explosion-proof cover, the impeller is connected to the motor through a motor shaft, and the motor, the impeller, the explosion-proof cover and the main machine air duct are all two-stage, so as to combine into two sets of two-stage fans connected by a coaxial central line, wherein the two-stage impellers are close to each other and rotate in opposite directions, and the same ends of the two-stage motor, the explosion-proof cover. Therefore, when the ventilation distance is long, the second wind wheel 22 of the counter-rotating fan 2 can exert the advantage of adjusting the pressure of the wind power area.
In some embodiments of the invention, n1 < n2 when the functional mode is detected as the no-wind mode, and n1 > n2 when the functional mode is detected as the wind mode. That is, when it is detected that the function mode is the no-wind mode, it is ensured that the no-wind blowing of the air conditioner 100 can be achieved by controlling the space between the first wind wheel 21 and the second wind wheel 22 to satisfy n1 < n2, and when it is detected that the function mode is the wind mode, it is ensured that the no-wind blowing of the air conditioner 100 can be achieved by controlling the space between the first wind wheel 21 and the second wind wheel 22 to satisfy n1 > n2, thereby facilitating the function mode adjustment of the air conditioner 100.
In some embodiments of the present invention, when the functional mode is detected as the no-wind mode, the first wind wheel 21 and the second wind wheel 22 are controlled to satisfy: and n1 is (0.5-1) n2, and when the functional mode is detected to be the wind sensation mode, the first wind wheel 21 and the second wind wheel 22 are controlled to meet the following conditions: n1 is (1-2) n 2. That is, in the no-wind mode, the following are satisfied between the first wind rotor 21 and the second wind rotor 22: n1 is (0.5 ~ 1) n2 to reach the effect of low sense of blowing, when having a wind mode, make and satisfy between first wind wheel 21 and the second wind wheel 22: n1 is (1-2) n2, thereby further improving the noise reduction effect.
In some embodiments of the present invention, the axial distance between the first wind wheel 21 and the second wind wheel 22 is d, where d is the distance between the blade tail circle of the first wind wheel 21 and the blade tip of the second wind wheel 22, and the chord length of the first wind wheel 21 is L, where d is greater than or equal to 0.3L and less than or equal to 1.5L. Thereby making the counter-rotating wind wheel have better efficiency and lower noise performance, and further improving the comfort of the air conditioner 100.
Furthermore, when d is more than or equal to 0.45L and less than or equal to 0.55L, the efficiency and the noise performance of the counter-rotating fan 2 are better.
It should be noted that, since the first wind wheel 21 and the second wind wheel 22 of the counter-rotating fan 2 are arranged at intervals, the pressure difference between the wind area of the first rotor 21 and the wind area of the second rotor 22 is therefore larger, and the second rotor 22 carries more pressure-rise tasks, in order to reduce the impact on the actual operational flow losses of the rotor 2, therefore, two-stage correction of the rotation speed of the first wind wheel 21 and the second wind wheel 22 is needed, so that the pressure of the wind power area of the first wind wheel 21 is increased to a certain extent, and the pressure in the wind power area of the second wind wheel 22 is reduced, the pressure difference in the two-stage wind power area is reduced, the pressure rise distribution is more reasonable, and the phenomenon of overloading of the secondary motor is prevented, so as shown in figures 1 and 4, in some embodiments of the invention, the rotational speed n1 of the first wind rotor 21 and the rotational speed n2 of the second wind rotor 22 satisfy the following relationship:
