201. Acquiring an indoor air pressure value and an outdoor air pressure value in real time;
it should be noted that, referring to step 101, a description thereof is omitted.
The air outlet door and the air inlet door are both provided with the same preset opening amplitude.
Wherein the air outlet door comprises at least one inner air outlet door and at least one outer air door; the intake damper includes at least one inner intake damper and at least one outer intake damper.
The number of the air doors and the size of each air door may be set according to the actual conditions of the apparatus and the real environment. If the number of the inner air outlet door, the inner air inlet door, the outer air inlet door and the outer air inlet door can be 1, the sizes are 600mm by 200mm, referring to fig. 4, fig. 4 shows the case that the number of the inner air outlet door, the inner air inlet door, the outer air inlet door and the outer air inlet door is 1, and specific setting positions are shown.
The inner air inlet door, the inner air outlet door, the outer air outlet door and the outer air inlet door are all provided with the same preset opening amplitude.
When the air pressure mode instruction is executed, the same opening amplitude can be set for the inner air inlet door, the inner air outlet door, the outer air outlet door and the outer air inlet door in advance so as to carry out subsequent adjustment. The preset opening amplitude is used as the basic amplitude of adjustment, and can be preset according to actual requirements. For example, the set rule may be set according to the magnitude of the target air pressure difference, and when the target air pressure value is larger than the actual air pressure difference, a larger opening width may be appropriately set as a basis for the subsequent opening width adjustment, for example, both of 50% and 60%.
202. When the air pressure mode instruction is received, an air pressure difference value between the indoor air pressure value and the outdoor air pressure value is calculated.
It should be noted that, reference may be made to step 102, and details thereof are not described herein.
203. When the air pressure mode instruction is a positive pressure mode instruction, comparing a target air pressure difference value corresponding to the positive pressure mode instruction with the air pressure difference value, and adjusting opening amplitude of the air outlet door and the air inlet door according to a comparison result, wherein the method comprises the following steps:
when the air pressure mode instruction is a positive pressure mode instruction; the opening amplitude of the inner air outlet door is adjusted to the maximum amplitude, and the opening amplitude of the outer air outlet door is adjusted to the minimum amplitude.
When the received air pressure mode command is a positive pressure mode command, the opening amplitude of the inner air outlet door is adjusted to the maximum amplitude, and the opening amplitude of the outer air outlet door is adjusted to the minimum amplitude, namely, the outer air outlet door is closed.
Comparing the target air pressure difference value corresponding to the positive pressure mode instruction with the air pressure difference value;
if the air pressure difference is smaller than the target air pressure difference, increasing the opening amplitude of the outer air inlet door and reducing the opening amplitude of the inner air inlet door according to the first preset adjusting amplitude;
if the air pressure difference is larger than the target air pressure difference, reducing the opening amplitude of the outer air inlet door and increasing the opening amplitude of the inner air inlet door according to the second preset adjusting amplitude.
It should be noted that, the first preset adjustment range and the second preset adjustment range may be preset according to actual situations, for example, the first preset adjustment range may be determined according to a rule that the opening range of the outer air inlet door is greater than that of the inner air inlet door and the sum of the opening ranges of the outer air inlet door and the inner air inlet door is 100%, and the second preset adjustment range may be determined according to a rule that the opening range of the outer air inlet door is less than that of the inner air inlet door and the sum of the opening ranges of the outer air inlet door and the inner air inlet door is 100%.
The first preset adjustment amplitude comprises an increased opening amplitude of the outer air inlet door and a decreased opening amplitude of the inner air inlet door; the second preset adjustment range comprises a reduced opening range of the outer air inlet door and an increased opening range of the inner air inlet door. Based on the preset opening amplitude of each air door, the opening amplitude of the inner air inlet door and the opening amplitude of the outer air inlet door are adjusted circularly and dynamically according to the comparison result of the target air pressure difference value and the calculated actual indoor and outdoor air pressure difference values.
For example, the opening amplitude of the outer air inlet door and the opening amplitude of the inner air inlet door are adjusted to 50% in advance, the first preset adjusting amplitude and the second preset adjusting amplitude are set to 5%, the air pressure difference at the current moment is compared with the target air pressure difference, if the air pressure difference obtained by calculation at the current moment is smaller than the target air pressure difference, the opening amplitude of the inner air inlet door with the amplitude of 5% is reduced, the opening amplitude of the outer air inlet door with the amplitude of 5% is increased, so that the opening amplitude of the outer air inlet door is larger than the opening amplitude of the inner air inlet door, at this time, the opening amplitude of the inner air inlet door is 45%, the opening amplitude of the outer air inlet door is 55%, and the sum of the opening amplitude of the outer air inlet door and the opening amplitude of the inner air inlet door is exactly 100%. If the air pressure difference value calculated at the current moment is larger than the target air pressure difference value, the opening amplitude of the outer air inlet door with the amplitude of 5% is reduced, the opening amplitude of the inner air inlet door with the amplitude of 5% is improved, the opening amplitude of the inner air inlet door is larger than that of the outer air inlet door, at the moment, the opening amplitude of the inner air inlet door is 55%, and the opening amplitude of the outer air inlet door is 45%. And (3) monitoring the indoor and outdoor air pressure difference in real time, and dynamically adjusting and correcting the opening amplitude of the inner air inlet door and the opening amplitude of the outer air inlet door according to the comparison result of the air pressure difference, so that the air pressure difference between the indoor and the outdoor reaches the target air pressure difference.
At this time, when the positive pressure mode instruction is executed, the interior of the air disinfection device mixes the indoor air received through the inner air inlet door and the outdoor air received through the outer air inlet door, and after the mixed air is disinfected and purified, the mixed air is output to the room through the inner air outlet door.
