The second crossflow blower may be operated at a certain weighted (50%) down speed (960 x 50% r/min rounded) based on the set operating speed. Further, the first guide plate 21, the first cross flow fan and the first throttling device 51 can be kept unchanged, the second guide plate 22 is completely closed to form strong air supply at the upper air outlet 11, and the micro-holes 23 are formed at the lower air outlet 11 for permeable air supply. The second predetermined temperature is between 35.8 ℃ and 36.2 ℃, preferably 36 ℃.
When the temperature of the surface layer of the skin of the human body is lower than a second preset temperature, the running frequency of the compressor is lower than the frequency set by a preset normal running program, namely the compressor runs in a frequency reduction mode (for example, the frequency is 42 Hz); at least making the rotating speed of the second cross-flow fan lower than the rotating speed set by a preset normal operation program; the opening degrees of the first throttle device 51 and the second throttle device 52 are both preset second optimum opening degrees Ka12, Ka 22. For example, the rotational speed of the second crossflow blower may be reduced by a certain weight (50%) based on the set operating speed (960 x 50% r/min rounded); of course, the second crossflow blower may also be operated at a rotational speed of 650 r/min. Further, when the temperature of the surface layer of the human skin is lower than the second preset temperature, the louvers 24 may also be set to a second set angle, for example, the vertical and horizontal louvers 24 may be set to the second set angle of the user. The first guide plate 21 and the first through-flow fan can be kept unchanged, the second guide plate 22 is completely closed, the upper air outlet 11 is formed to supply air strongly, the lower air outlet 11 is formed to supply air in a penetrating manner through the micropores 23, the preset opening degree of the throttling device is controlled, the political law device is controlled to be overheated, and the temperature of the air outlet 11 is increased.
In some embodiments of the present invention, when the air conditioner input control module, such as a remote controller, is configured with a leg-blowing prevention button, and the user directly remotely controls the leg-blowing prevention mode, the control method further includes obtaining a leg-blowing prevention command input by the user, so that the second guide plate 22 completely shields the second air-out area, so that the airflow flows out of the housing 10 through the plurality of micro holes 23, and the opening degree of the second throttling device 52 is a preset fourth optimal opening degree Ka24, and the fourth optimal opening degree Ka24 of the second throttling device 52 may be equal to the third optimal opening degree Ka23 of the second throttling device 52; the rotational speed of the second crossflow blower is made lower than the rotational speed set by the preset normal operation program, for example 650r/min or the second crossflow blower can be operated at a certain weighted (50%) down speed (960 x 50% r/min rounded) based on the set operation rotational speed. Further, the louvers 24 may also be brought to a third set angle, such as by bringing the vertical and horizontal louvers 24 to the user's third set angle. The opening degree of the first throttle device 51 may also be made a preset third optimum opening degree Ka 13. And the running frequency of the compressor can be lower than the frequency set by the preset normal running program, namely the compressor is in down-frequency running (for example, the frequency is 42 Hz). Of course, in other embodiments, the compressor may be operated at a frequency (e.g., 61Hz) set by a predetermined normal operation program.
In order to improve the stability of the operation of the air conditioner, the control method further comprises a starting stabilization step. The starting stabilization step comprises the steps of enabling the opening degrees of the first throttling device 51 and the second throttling device 52 to be respectively preset first optimal opening degrees; the first air outlet area is completely opened by the first guide plate 21, and the second air outlet area is completely opened by the second guide plate 22; enabling the first cross flow fan and the second cross flow fan to operate according to the rotating speed set by a preset normal operation program; enabling a compressor of the air conditioner to operate according to a frequency set by a preset normal operation program; and detecting the exhaust temperature of the compressor, and determining to finish the starting stabilization step after the exhaust temperature is in a stable state (for example, the exhaust temperature is determined to be in the stable state when the difference between the two detected exhaust temperatures is less than or equal to 2 ℃) and the operation is carried out for a preset time (for example, 5 min). That is, the start-up stabilization step may cause the air conditioner to enter a full-wind-speed, full-heat-exchange air conditioning mode, and cause the exhaust temperature to be in a steady state and to run for a preset duration. After the step of starting and stabilizing is completed, the air conditioner can detect the temperature of the surface layer of the skin of the human body, or the step of obtaining the leg blowing prevention instruction input by the user is carried out.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
