The spoiler mode can be set to indoor air circulation, fresh air delivery, etc. When the air conditioning module operates in a refrigerating mode, the turbulence module can convey airflow which does not pass through the indoor heat exchanger.
As shown in fig. 1 to 4, according to a turbulence method of an air conditioner including an air conditioning module and a turbulence module according to an embodiment of the present invention, the turbulence method includes: when the air conditioning module is in a cooling mode, if the indoor temperature T1 is not greater than a first threshold value, the air outlet angle alpha and/or the air outlet speed n of the turbulent flow module are determined according to the operating frequency fr and/or the operating current dL of the compressor.
The first threshold value is the temperature at which the indoor temperature (ambient temperature) reaches comfortable air supply, and can be reasonably selected according to different users, so that the temperature at which the user using the air conditioner feels comfortable at present is used as the standard, and the temperature can also be reasonably selected according to regions, seasons, humidity and the like.

According to the turbulence method of the air conditioner, the air outlet angle and the air outlet speed of the turbulence module are adjusted according to the compressor when the indoor temperature reaches the preset range, and the comfort is improved.
In addition, in the actual use process, when the air conditioner is in a refrigerating state, the comfort of a user can be effectively improved through the adjustment of the turbulence module, and when the air conditioner is in a heating state, the discomfort of the user can be enhanced by blowing indoor air which does not pass through the heat exchanger through the turbulence module, so that the invention is mainly applied to the condition that the air conditioner is in a refrigerating mode.

Of course, the invention is not only used in the cooling mode, but also can control the turbulent flow module by using the control mode of the invention when the air conditioner is in the heating mode or other non-cooling modes.
In some embodiments, as shown in fig. 1, the method for disturbing the flow includes: detecting an indoor temperature T1 when the air conditioning module is in a cooling mode, if the indoor temperature T1 is not greater than a first threshold value, judging the running frequency fr of the compressor,
if the operating frequency fr of the compressor is not less than the second threshold value, the turbulent flow module still needs to have a good turbulent flow effect. At this time, the air outlet angle alpha of the turbulence module is increased by a first preset angle, and the air outlet angle alpha of the turbulence module is not larger than the maximum air outlet angle alpha max. The turbulent flow effect can be improved to a certain extent.
If the operating frequency fr of the compressor is less than the second threshold value, the adverse effect of the spoiler module on comfort needs to be reduced. At this time, the air outlet angle alpha of the turbulence module is reduced by a second preset angle, and the air outlet angle alpha of the turbulence module is not smaller than the minimum air outlet angle alpha min.

Specifically, the flow disturbing method comprises the following steps: detecting an indoor temperature T1 when the air conditioning module is in a cooling mode, if the indoor temperature T1 is not greater than a first threshold value, judging an operating current dL of the compressor,
if the operating current dL of the compressor is not less than the third threshold value, the turbulent flow module is required to have a good turbulent flow effect. At this time, the air outlet angle alpha of the turbulence module is increased by a first preset angle, and the air outlet angle alpha of the turbulence module is not larger than the maximum air outlet angle alpha max. The turbulent flow effect can be improved to a certain extent.
If the operating current dL of the compressor is less than the third threshold, the detrimental impact of the spoiler module on comfort needs to be reduced at this time. At this time, the air outlet angle alpha of the turbulence module is reduced by a second preset angle, and the air outlet angle alpha of the turbulence module is not smaller than the minimum air outlet angle alpha min. The effect of vortex can be reduced to a certain extent, and the comfort is improved.

When the turbulence guide plate is at the minimum opening angle, the turbulence module is at the minimum air outlet angle alpha min, and the minimum opening angle of the turbulence guide plate is in the range of 0-30 degrees. And when the turbulence guide plate is at the maximum opening angle, the turbulence module is at the maximum air outlet angle alpha max, and the maximum opening angle of the turbulence guide plate is within the range of 30-150 degrees.
In some embodiments, the difference between the indoor temperature T1 and the first threshold is Ts ℃, where Ts is a value without units, and neither the first predetermined angle nor the second predetermined angle is greater than θ × Ts. According to the difference value between the indoor temperature T1 and the first threshold value, the current operation state of the air conditioner can be determined, so that the operation condition of the turbulence module is adjusted, and the comfort of air supply of the air conditioner is further effectively improved.
Where θ may be in the range of 0.5 ° to 10 °, e.g., θ is 0.5 °, 1 °, 5 °, etc.

At this moment, the air outlet speed n of the turbulence module is increased by a first preset value, and the air outlet speed n of the turbulence module is not greater than the maximum air outlet speed Nmax, so that the turbulence effect can be improved to a certain extent.
If the operating frequency fr of the compressor is less than the second threshold value, the adverse effect of the spoiler module on comfort needs to be reduced. At this time, the air outlet speed n of the turbulence module is reduced by a second preset value, and the air outlet speed n of the turbulence module is not less than the minimum air outlet speed Nmin. The effect of vortex can be reduced to a certain extent, and the comfort is improved.
In addition, as shown in fig. 4, the present invention may also determine the operation state of the air conditioning module according to the current of the compressor, so as to determine the operation state of the spoiler module according to the operation state of the air conditioning module, thereby effectively improving the comfort level of the user.
Specifically, the flow disturbing method comprises the following steps: detecting an indoor temperature T1 when the air conditioning module is in a cooling mode, judging an operating current dL of the compressor if the indoor temperature T1 is not greater than a first threshold value,
if the operating current dL of the compressor is not less than the third threshold value, the turbulent flow module is required to have a good turbulent flow effect. At this moment, the air outlet speed n of the turbulence module is increased by a first preset value, and the air outlet speed n of the turbulence module is not greater than the maximum air outlet speed Nmax, so that the turbulence effect can be improved to a certain extent.
If the operating current dL of the compressor is less than the third threshold, the detrimental impact of the spoiler module on comfort needs to be reduced at this time. At this time, the air outlet speed n of the turbulence module is reduced by a second preset value, and the air outlet speed n of the turbulence module is not less than the minimum air outlet speed Nmax. The effect of vortex can be reduced to a certain extent, and the comfort is improved.
In addition, as can be seen from the foregoing description, the outlet wind speed n of the spoiler module is not less than the minimum outlet wind speed Nmin and not greater than the maximum outlet wind speed Nmax, that is, in the process of adjusting the outlet wind speed n of the spoiler module, the outlet wind speed n of the spoiler module can only be reduced to the minimum outlet wind speed Nmin at the minimum, and the outlet wind speed n of the spoiler module can only be increased to the maximum outlet wind speed Nmax at the maximum.
When the outlet air speed n of the turbulence module needs to be increased, when the outlet air speed n of the turbulence module reaches Nmax, the outlet air speed n of the turbulence module is not adjusted; when the air outlet speed n of the turbulence module needs to be reduced, when the air outlet speed n of the turbulence module reaches Nmin, the air outlet speed n of the turbulence module is not adjusted.
In addition, in some embodiments, after each detection is completed, a fixed angle needs to be adjusted for the outlet wind speed n of the turbulence module, and if the fixed angle is greater than a difference between the outlet wind speed n and the maximum outlet wind speed Nmax or the minimum outlet wind speed Nmin, the outlet wind speed n is adjusted to the maximum outlet wind speed Nmax or the minimum outlet wind speed Nmin without being adjusted according to the fixed angle; or adjusting according to the fixed angle, at this time, the outlet wind speed n may be greater than the maximum outlet wind speed Nmax or less than the minimum outlet wind speed Nmin, at this time, if the outlet wind speed n is greater than the maximum outlet wind speed Nmax, the outlet wind speed n needs to be continuously increased after the next detection is completed, the adjustment is not performed, and if the outlet wind speed n is less than the minimum outlet wind speed Nmin, the outlet wind speed n needs to be continuously decreased after the next detection is completed, the adjustment is not performed.

In some embodiments, the difference between the indoor temperature T1 and the first threshold is Ts ℃, where Ts is a value without units, and neither the first predetermined value nor the second predetermined value is greater than w × Ts. According to the difference value between the indoor temperature T1 and the first threshold value, the current operation state of the air conditioner can be determined, so that the operation condition of the turbulence module is adjusted, and the comfort of air supply of the air conditioner is further effectively improved.
Wherein w can be in the range of 5r/min to 50r/min, such as 5r/min, 10r/min, 20r/min, and the like.
In the foregoing embodiment, the first threshold is the comfortable air supply temperature, that is, in a normal case, when the indoor temperature reaches the first threshold, the human body will be in a more comfortable state, but the comfortable temperatures sensed by the human bodies at different positions, in different seasons, in different gender ages, etc. are different, so that the first threshold can be adjusted around the comfortable air supply temperature. For example, in the practical use process of the air conditioner, the human body generally feels comfortable at 27 ℃, and in order to adapt to different people, the range of the first threshold value can be set to be within a reasonable range, so as to meet the requirement of different people on comfort, for example, the first threshold value is within the range of 23 ℃ to 31 ℃.
