s3, judging whether the second temperature difference value T2 is larger than a second preset value or not, if so, adjusting the rotating speed of the inner fan to a higher rotating speed for running, adjusting the swing blade angle to a third swing blade angle, and entering the step S4, otherwise, adjusting the rotating speed of the inner fan to a low rotating speed for running, adjusting the swing blade angle to a fourth swing blade angle, and entering the step S5;
in this step, the second preset value is selected according to an actual system, taking 35 machine products as an example, the angle can be 1, the third swing blade angle is selected according to simulation calculation to ensure temperature uniformity and heating effect, in this stage, when the temperature difference between the indoor temperature and the set temperature is reduced, a slightly smaller fan rotating speed (a "higher rotating speed" smaller than the "high rotating speed") and a slightly smaller swing blade angle (a "third swing blade angle" smaller than the "maximum wind sweeping angle") are adopted, and when the temperature difference is further reduced (smaller than or equal to the second preset value), a slightly smaller fan rotating speed (a "lower rotating speed" smaller than the "higher rotating speed") is adopted, considering hot air floating, in order to avoid reducing the air volume while reducing the fan rotating speed, a larger swing blade angle (a "fourth swing blade angle" larger than the "third swing blade angle") is adopted, thereby ensuring the heating comfort of the room; the fourth swing blade angle is selected to ensure that the air supply position is lower, the room temperature is maintained, and the stability of the room temperature is ensured.
S4, judging whether the second temperature difference value T2 is larger than the first preset value plus the temperature compensation value T, if yes, adjusting the rotating speed of the inner fan to a high rotating speed for running, and adjusting the swing blade angle to the maximum range for sweeping; otherwise, the rotating speed and the swing blade angle are unchanged, and the step S4 is returned to continue judging;
in the step, the temperature compensation value T can be selected according to different systems and environments, so that the heating effect is ensured and frequent switching is avoided.
S5, judging whether the second temperature difference value T2 is larger than a second preset value and a temperature compensation value T, if yes, adjusting the rotating speed of the inner fan to a higher rotating speed for operation, adjusting the swing blade angle to a third swing blade angle, and entering the step S4; otherwise, the rotation speed and the swing blade angle are unchanged, and the step S5 is returned to continue judging.
It should be noted that the first preset value and the second preset value in the two embodiments are set according to an actual system, and the set values of the refrigeration mode and the heating mode may be different according to the actual system; the temperature compensation value T is set according to an actual system, and the compensation values of the refrigeration and heating modes may be different according to the actual system. In addition, the "high rotation speed", "higher rotation speed" and "low rotation speed" may be actually defined according to threshold values, such as: the rotation speed exceeding n revolutions per minute is the "high rotation speed", the rotation speed lower than m revolutions per minute is the "low rotation speed", and the rotation speed between m and n is the "higher rotation speed", and those skilled in the art can understand that m and n can also be set according to the actual system.
The "swing blade angle" in the present invention is the size of the "opening degree" corresponding to the swing blade closed position.
