When the room fresh air replacement is operated, on the basis of primary negative pressure generated by the suction of an exhaust system and a room dirty air return pipe, a suction port generates secondary negative pressure when a door fan coil is operated, so that the air pressure at the door head in the room is the lowest, a maximum pressure difference is formed between a fresh air port of the door head and a fresh air region of an aisle, the aisle fresh air is pulled to quickly flow into the room through the fresh air port of the door head, is sucked and boosted by the fan coil to be emitted to an outer wall, is reflected by the outer wall and then flows back to one side of an inner wall where the door is positioned, and the room dirty air is driven to enter the room return pipe, so that the problem of fresh air short circuit in room replacement is fundamentally solved, and the technology endowment of ' secondary negative pressure ', ' deep suction high-level exhaust ', and room replacement clear ' is realized, as shown in figure 1.
In the above-mentioned room fan coil relay power-based no blast pipe send row to combine to arrange as the two-way fresh air system of whole room, although there is the secondary negative pressure vortex in the fan coil inlet scoop in each room in the furred ceiling, this secondary negative pressure vortex can become the power that living room passageway new trend gushes into the room, but still face the problem how the new trend that sends into living room passageway spanned the door.

In this embodiment, the thickness of the fixed circular arc piece 65 is greater than that of the circular arc sliding piece 63, when the dirty air in the room is discharged through the air return pipe 4 of the room, that is, the ventilation opening 66 is opened, the electric air valve 6 sucks air inwards, please refer to fig. 9, the inside of the cylindrical pipe is negative pressure, the outside of the cylindrical pipe is positive pressure, the air outside of the ventilation opening 66 (that is, the air in the room) is sucked into the cylindrical pipe through the ventilation opening 66, the outer layer cylindrical sleeve 62 only limits the circular arc sliding piece 63, and the pressure difference between the inside and the outside of the air channel after the ventilation opening 66 is closed presses the circular arc sliding piece 63 on the outer surface of the inner layer cylindrical sleeve 61, please refer to fig. 10, so that the inside of the inner layer cylindrical sleeve 61 is the air channel body.
Example 3
This example was further modified based on examples 1 and 2. Referring to fig. 11, the present embodiment provides a whole-room fresh air system with an electric air door, which is used for a room group, wherein the room group comprises a plurality of rooms and a public space communicated with each room, each room is provided with a door 1, the door 1 comprises a door leaf 12, each room comprises the room fresh air systems described in embodiments 1 and 2, a room fresh air port 121 of each room is communicated with the public space, the electric air door described in embodiments 1 and 2 is arranged on the room fresh air port 121, and the whole-room fresh air system comprises:
The main air inlet is arranged on the outer wall of the public space and is used for realizing the communication between the public space and the outside atmosphere of the room group, and a fresh air module 10 is arranged on the main air inlet;
the main air outlet is arranged on the outer wall of the room group and communicated with the outside air of the room group, and an air exhaust module 20 is arranged on the main air outlet;
The main exhaust pipe is communicated with the main exhaust outlet and is respectively communicated with each room through a plurality of room return air pipes 4.
When the whole-house fresh air system is operated, fresh air replacement is not needed in some rooms, so that the room fresh air inlets 121 of the rooms and the electric air valves 6 on the room return air pipes 4 can be selectively closed, and the room fresh air inlets 121 of the rooms requiring fresh air replacement and the electric air valves 6 on the room return air pipes 4 are opened.
When the whole-room fresh air replacement operation is performed, the fresh air module 10, the room fan coil 5 and the air exhaust module 20 are started, the fresh air positive pressure pushing of the fresh air module 10, the relay conveying of the room fan coil 5 and the negative pressure pumping and exhausting of the dirty air of the air exhaust module 20 are simultaneously forced, so that the whole-room fresh air replacement with 'two-way flow' is formed together, and the whole-room fresh air replacement process is divided into three sections:
1. fresh air feeding section
After the fresh air module 10 sucks in ambient fresh air and carries out pretreatment such as filtration, cooling, dehumidification (heating), and the like, the fresh air with the temperature, humidity and cleanliness reaching the standards is directly sent into a living room aisle serving as a public space in a positive pressure manner, and directly abuts against the doors 1 of each room;
2. fresh air replacement section
Under the secondary negative pressure generated by the suction of the air suction inlet 52 of the room fan coil 5 which is close to the room fresh air inlet 121 on the basis of the primary negative pressure generated by the suction of the air return inlet of the room air return pipe 4, the air suction inlet 52 of the room fan coil 5 is positioned in the lowest pressure area of the room, a large pressure difference is formed between the close room fresh air inlet 121 and the air suction inlet 52 of the room fan coil 5, the room door 1 fresh air rapidly floods into the room through the room fresh air inlet 121, is sucked, boosted and accelerated by the room fan coil 5 to be directed to the outer wall side of the room, and is reflected by the outer wall to flow back to the inner wall side of the room door 1, so that the room dirty air is pressed into the room air return pipe 4;
3. Dirty air discharge section
Dirty air entering the room return air pipe 4 quickly flows into the main exhaust pipe, enters the exhaust module 20, is boosted again by the exhaust fan, and finally is exhausted to the outdoor atmosphere for diffusion.
The foregoing describes specific embodiments of the present application. It is to be understood that the application is not limited to the particular embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without affecting the spirit of the application.
