In one example, the fan 22 is disposed on the air intake side of the purification section 21.
In one example, the fan 22 is disposed on the air outlet side of the purification section 21.
In one example, as shown in fig. 7, the intake vent 1 is disposed above an inlet of the indoor and outdoor buffer 7.
In one example, the first conduit 4A and/or the second conduit 4B have any one or more of the following disposed thereon:
damping device, static pressure case, silencer.
In one example, the first pipe 4A or the second pipe 4B may be a pressure-resistant hose, a metal pipe, or the like.
In one example, the system for preventing outdoor air contaminants from entering the chamber further comprises an air volume control system (not shown).
In one example, the air volume control system comprises at least one valve arranged on said first duct 4A and/or second duct 4B. The valve member may be a shut-off valve, a check valve, a gate valve, or the like. The flow of the air to be cleaned and/or the clean air 13 can be controlled by means of a valve.
In one example, the air volume control system includes a differential pressure control system (not shown). The pressure difference control system comprises a controller and a pressure difference monitor, and the controller and the fan 22 can be connected through a lead or a network. The pressure difference monitor is used for monitoring the pressure difference between the indoor buffer area 7 and the outdoor buffer area 5. The differential pressure monitor may also be used to monitor wind speed at door a 8 (or door B6, or doors a 8 and B6). And the differential pressure monitor transmits the monitored differential pressure signal or the monitored wind speed signal to the controller in real time. The controller adjusts the rotating speed of the fan 22 in real time according to the pressure difference signal or the air speed signal, so that the air quantity introduced by the fan 22 can be adjusted.
Next, in one example, the differential pressure control system provided by the present invention will be specifically described. The operation state of the fan 22 is controlled by a pressure difference control system, so that the air pressure difference between the inside and outside buffer areas 7 and the outside 5 is maintained between positive 10Pa (a first threshold value) and positive 20Pa (a second threshold value) (the air pressure in the inside and outside buffer areas 7 is 10Pa to 20Pa higher than the air pressure in the outside 5), when the value of the pressure difference monitored by a pressure difference monitor is smaller than the positive 10Pa (the first threshold value) (the air pressure in the inside and outside buffer areas 7 is less than 10Pa of the air pressure in the outside 5), the controller controls the fan 22 to operate, the fan 22 introduces air from the outside 5 through the air inlet 1, the introduced air is sent into the inside and outside buffer areas 7 through the air outlet 3 through the second pipeline 4B after passing through the purification section 21, a local micro-positive pressure environment is created in the inside and outside buffer areas 7 by using the clean air 13, wherein most of the clean air 13 is pressed into the inside and outside buffer areas 7; when the air quantity introduced by the fan 22 reaches a certain value, and the value of the pressure difference monitored by the pressure difference monitor is larger than positive 20Pa (a second threshold value) (the air pressure in the inner and outer buffer areas 7 is higher than the air pressure of the outdoor 5 by 20Pa), the controller controls the fan 22 to stop running, and at the moment, the air pressure in the inner and outer buffer areas 7 is still larger than the air pressure of the outdoor 5, so that the inner and outer buffer areas 7 are in a local micro-positive pressure environment, and outdoor air pollutants are prevented from entering the indoor space from a building entrance. When the pressure in the internal and external buffer areas 7 is reduced to a certain value, namely when the value of the pressure difference monitored by the pressure difference monitor is smaller than positive 10Pa (a first threshold value) (the pressure in the internal and external buffer areas 7 is higher than the pressure in the outdoor area 5 and is less than 10Pa), the controller controls the fan 22 to operate again, and when the value of the pressure difference monitored by the pressure difference monitor is larger than positive 20Pa (a second threshold value) (the pressure in the internal and external buffer areas 7 is higher than the pressure in the outdoor area 5 and is 20Pa), the controller controls the fan 22 to stop operating, and the above steps are repeated.
The differential pressure monitor can comprise an air pressure sensor, an air speed sensor and a PM2.5 concentration sensor. The working principle of the differential pressure monitoring instrument is that the pressure signal or the wind speed signal or the PM2.5 concentration signal and the like are received by the sensor, the received signals are converted into electric signals, and then the electric signals are sent to the controller. After receiving the electric signal, the controller controls the fan 22 according to the electric signal, thereby adjusting the air quantity. The controller can be specifically a motor controller or a wind speed controller.
The pressure difference monitor may include two or more pressure sensors, at least one pressure sensor is respectively disposed at the outdoor 5 and the indoor and outdoor buffer areas 7, and is used for monitoring the pressure of the outdoor 5 and the indoor and outdoor buffer areas 7, respectively, and then the monitored pressure signal is converted into an electrical signal and sent to the controller, and the controller compares the pressure value, thereby controlling the fan 22. Or the differential pressure monitor compares the pressure values, converts the comparison result, namely the differential pressure value, into an electric signal and sends the electric signal to the controller.
The wind speed sensor of the differential pressure monitor can be arranged on the outer side of the door A8 (or the door B6, or the door A8 and the door B6), the wind speed of the door A8 (or the door B6, or the door A8 and the door B6) is monitored, then the wind speed information is converted into an electric signal, and the electric signal is sent to the controller.
In one example, the air volume control system includes a manual controller (not shown) for manually controlling the blower 22. The manual controller is connected to the blower 22 via a wire or network.
The air quantity can be controlled by the manual controller speed regulation fan 22 according to the indoor and outdoor pressure difference (the air pressure in the indoor buffer area 7 is subtracted from the outdoor 5 air pressure), and the rotating speed of the fan 22 is increased when the pressure difference is large, so that the air quantity is increased; when the pressure difference is small, the rotating speed of the fan 22 is reduced, and the air volume is reduced.
The air quantity can be controlled by a manual controller according to the outdoor 5 air quality. According to the air quality of the outdoor 5, when the air quality of the outdoor 5 does not reach the standard, the fan 22 is started through the manual controller; when the outdoor 5 air quality reaches the standard, the blower 22 is turned off by the manual controller.
The air volume can be controlled by a manual controller according to the wind speed at the a door 8 (or the B door 6, or the a door 8 and the B door 6). When the wind speed at the door A8 (or the door B6, or the door A8 and the door B6) is high, the rotating speed of the fan 22 is increased through the manual controller, and the wind quantity is increased; when the wind speed at the A door 8 (or the B door 6, or the A door 8 and the B door 6) is small, the rotating speed of the fan 22 is reduced, and the wind volume is reduced.
In one example, the intake vent 1 is provided with a filter.
In one example, the filter includes a desiccant.
