Embodiment 1
[0042] In the embodiment of the present invention, the manual control panel of the indoor room is compatible with the automatic control system, thereby realizing the control and adjustment of positive pressure values in multiple rooms. The automatic control scheme and the manual control scheme are introduced respectively below.
[0043] 1. Automatic control scheme
[0044] figure 1 It is a flowchart of an automatic control method for positive pressure values in different rooms according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0045] Step S101, monitoring the indoor positive pressure value of each room;
[0046]Step S102, comparing the indoor positive pressure value with the preset positive pressure value, and correspondingly controlling the opening or closing of the exhaust dampers of each room according to the comparison result.
[0047] Through this embodiment, the automatic control and adjustme...
Embodiment 2
[0065] corresponds to figure 1 Introducing the automatic control method for positive pressure values in different rooms, this embodiment provides an automatic control device for positive pressure values in different rooms, such as image 3 The structural block diagram of the automatic control device for positive pressure values in different rooms shown, the device includes:
[0066] Monitoring module 10, for monitoring the indoor positive pressure value of each room;
[0067] The control module 12 is connected to the monitoring module 10, and is used for comparing the indoor positive pressure value with the preset positive pressure value, and correspondingly controlling the opening or closing of the exhaust air valves of each room according to the comparison result.
[0068] Through this embodiment, the automatic control and adjustment of the positive pressure values in different rooms is realized, and there is no need to temporarily change the room according to the d...
Embodiment 3
[0087] Figure 5 It is a structural schematic diagram of different room positive pressure value control systems according to an embodiment of the present invention, such as Figure 5As shown, the system includes: pressure sensors arranged in each room, air supply damper (electric air supply damper S), exhaust damper (electric exhaust damper P), and a controller; wherein, the pressure sensor , to monitor the indoor positive pressure value of each room; the controller is used to compare the indoor positive pressure value with the preset positive pressure value, and control the opening or closing of the exhaust air valve of each room according to the comparison result; Both the wind damper and the exhaust damper are closed. Based on this, automatic control and adjustment of positive pressure values in different rooms can be realized. Figure 5 In the illustration, pressure sensors and interactive panels are set in each room as an example.
[0088] In order to realize the man...
