The specific embodiment of the indoor negative pressure control terminal of the present invention is substantially the same as the following embodiments of the indoor negative pressure control method, and will not be described herein again.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of an indoor negative pressure control method according to the present invention, the indoor negative pressure control method including:
in step S10, the indoor air pressure value of the indoor area is acquired by the pressure sensor.
The terminal of the embodiment of the invention can be a PC, and can also be a terminal device with a data processing function, such as a smart phone, a tablet computer, a portable computer and the like. The terminal is connected with a pressure sensor arranged in an indoor area, and the indoor air pressure value of the indoor area is detected in real time through the pressure sensor. One or more indoor areas may be provided, and this embodiment is not limited specifically. At least one pressure sensor is installed in each indoor area, and when a plurality of pressure sensors are provided, any one detection result can be randomly used as the indoor air pressure value of the indoor area, or the average value of the detection results of the plurality of pressure sensors can be used as the indoor air pressure value of the indoor area. The installation position of the pressure sensor may be any position in the indoor area, and this embodiment is not particularly limited.
And step S20, comparing the acquired indoor air pressure value with a corresponding preset negative pressure value.
Since a specific air pressure value needs to be generated for the indoor area, after the indoor air pressure value of the indoor area is obtained, the obtained indoor air pressure value needs to be compared with a preset negative pressure value preset in the terminal, so that whether the current indoor air pressure value of the indoor area reaches the preset negative pressure value is judged. The preset negative pressure value can be set according to the actual situation, and the preset negative pressure value of each indoor area can be the same or different, and is not specifically limited in this embodiment.
And step S30, adjusting the air inflow of the air inlet fan corresponding to the indoor area and the air discharge of the air outlet fan corresponding to the indoor area according to the comparison result, so that the pressure value of the indoor area is maintained at the preset negative pressure value.
According to the comparison result of the obtained indoor air pressure value and the corresponding preset negative pressure value, whether an indoor area with the indoor air pressure value inconsistent with the preset negative pressure value exists in the indoor area or not can be determined, if the indoor area exists, the air inflow of an air inlet fan corresponding to the indoor area and the air discharge of a corresponding air outlet fan are adjusted, and the adjusted indoor air pressure value reaches the preset negative pressure value; if the indoor area does not exist, keeping the air inflow of the air inlet fan corresponding to the indoor area and the air discharge of the air outlet fan corresponding to the indoor area unchanged, and keeping the indoor air pressure value at the preset negative pressure value.
Specifically, the step S30 specifically includes:
step S301, when the indoor air pressure value of an indoor area in the indoor area is higher than a preset negative pressure value corresponding to the indoor area, reducing the air intake amount of the air inlet fan and/or increasing the exhaust amount of the corresponding air outlet fan;
step S302, when the indoor air pressure value of an indoor area in the indoor area is lower than a preset negative pressure value corresponding to the indoor area, increasing the air intake amount of the air inlet fan and/or reducing the exhaust amount of the corresponding air outlet fan;
step S303, when the indoor air pressure value of the indoor area is equal to the corresponding preset negative pressure value, keeping the air inflow of the air inlet fan and the air discharge of the corresponding air outlet fan unchanged.
It should be noted that the air intake fan here may be set up separately in each indoor area, also may set up only one total air intake fan, because the indoor area can't achieve the isolation under the ideal state, still there is certain air leakage rate, therefore only need set up one total air intake fan can guarantee the use demand too; however, since the negative pressure value required to be generated in each indoor area may be different, the air outlet fan needs to be separately installed in each indoor area.
The embodiment obtains the indoor air pressure value corresponding to the indoor area in real time through the pressure sensor of each indoor area, compares the obtained indoor air pressure value with the preset negative pressure value corresponding to the indoor area, determines whether the indoor area with the inconsistent preset negative pressure value exists according to the comparison result, and adjusts the indoor air pressure value by adjusting the air input of the air inlet fan corresponding to the indoor area and the exhaust amount of the corresponding air outlet fan if the indoor area exists, so that the indoor air pressure value of each indoor area is continuously maintained at the corresponding preset negative pressure value, thereby ensuring that the air pressure value of the indoor area reaches the negative pressure value required by prevention and control, effectively blocking the indoor polluted air from flowing outdoors, and avoiding the spread of respiratory system diseases.
Further, referring to fig. 3, fig. 3 is a flowchart illustrating an indoor negative pressure control method according to a second embodiment of the present invention. Based on the above-mentioned embodiment shown in fig. 2, when there are a plurality of indoor areas, before the step S30 adjusts the intake air amount of the intake air fan corresponding to the indoor area and the exhaust air amount of the exhaust air fan corresponding to the indoor area according to the comparison result, the method includes:
step S311, obtaining preset negative pressure values and indoor volumes corresponding to the plurality of indoor areas, and calculating unit displacement of each indoor area according to the preset negative pressure values and the indoor volumes corresponding to the plurality of indoor areas.
When the number of the indoor areas is multiple, the preset negative pressure value and the indoor volume corresponding to each indoor area need to be obtained before exhausting the plurality of indoor areas because the preset negative pressure value and the indoor volume of each indoor area may be different, and the unit exhaust volume of each indoor area is calculated according to the preset negative pressure value and the indoor volume corresponding to each indoor area. It should be noted that the indoor volume corresponding to each indoor area herein may be obtained by a user according to actual measurement, or obtained by acquiring an indoor area photograph through an indoor camera and analyzing through a terminal, which is not specifically limited in this embodiment. The unit displacement is the volume of gas to be discharged when the air outlet fan finishes primary air discharge and the air in the indoor area is reduced from the external air pressure value to the preset negative pressure value. Assuming that the preset negative pressure value of the indoor area is-15 Pa and the indoor volume is 5m, the unit exhaust volume V of the indoor area1＝15＊5＝75m3。
Step S312, respectively calculating a first exhaust duration required by each indoor area from the outside air pressure value to the preset negative pressure value according to the unit exhaust amount and the corresponding preset exhaust frequency.
Because each indoor area has the index of the exhaust frequency, when the exhaust fan exhausts, the first exhaust time required for each indoor area to be reduced from the external air pressure value to the preset negative pressure value is calculated according to the unit exhaust volume of the indoor area and the corresponding preset exhaust frequency. Based on the above example, when the number of times of ventilation of the indoor area is 15 times/hour, then the first exhaust period T of the indoor area1＝(V1/15＊V1) ＊ 3600-240 s, it should be noted that the preset number of exhaust times can be set according to the actual situation, and this embodiment is not limited to the aboveThe examples are not particularly limited.
And S313, respectively controlling the air outlet fans corresponding to the indoor areas to exhaust air according to the first exhaust duration until the pressure values corresponding to the indoor areas all reach preset negative pressure values.
After the first exhaust time of each indoor area is obtained, the indoor areas can be exhausted, the indoor areas are in a closed state at the moment, the air inlet fan is controlled to stop air inlet, the air outlet fan corresponding to each indoor area is controlled to continuously operate for the first exhaust time and then exhaust is stopped, and the indoor air pressure value of each indoor area is reduced to the corresponding preset negative pressure value from the external air pressure value.
