Embodiment 1

[0033] Such as Figure 1-7 shown.

[0034] A fresh air ventilation system for a residential suite with a dual-channel pressurized exhaust device, including a main exhaust fan 1, an air suction pipe 2 leading to each room, the outlet end of the air suction pipe 2 and the inlet of the main exhaust fan 1 The gas end is connected, and the installation position of the main exhaust fan is the same as that of the prior art. The suction pipe 2 can be an actual plastic pipe, or a pipe formed by masonry during residential construction, or a pipe installed in a suspended ceiling or a false beam. pipeline, the suction pipe 2 is provided with a plurality of suction ports 3 communicating with the room to be ventilated. In order to control the use, each suction port 3 can be equipped with a controllable gate, and the gate can be opened to perform Ventilation, the gate is closed, then the room cannot be ventilated. One or more multi-channel booster devices 4 are installed on the straight se...

Embodiment 2

[0039] Such as Figure 8 shown.

[0040]The difference between the present embodiment and the first embodiment is that the multi-channel supercharging device is installed on the straight pipe section of the suction pipe, and the air channels in the supercharging device are also linear structures accordingly.

Embodiment 3

[0042] Such as Figure 2-7 shown.

[0043] A multi-air channel pressurization device for a fresh air ventilation system in a residential suite, including a housing 9, the housing 9 may be an integral ring structure ( Figure 4 ), or a half-shell structure ( figure 2 , 3 shown), the two ends of the housing 9 are detachably connected to the suction duct, and the housing 9 is provided with two air ducts (also three, four or even more, at least one of which is not Installation includes any accessories of the supercharger blower), wherein an air duct is equipped with a supercharger fan 5, and the described air duct can be a linear structure (as shown in 8), a circular arc structure ( Figure 4 shown in), with corner structures ( figure 2 , 3 ) or a combination thereof, when using figure 2 , 3 In the shown structure with corners, the corners can be directly used as a part of the shell, that is, a half-shell structure. One or both ends of the air duct where the booster fan...

Abstract

A residence flatlet fresh air changing system provided with a double air duct pressurizing exhausting device comprises a main exhaust fan (1) and an air absorbing pipeline (2) which is communicated with all the rooms, wherein, an air outlet end of the air absorbing pipeline (2) is connected with an air inlet end of the main exhaust fan (1), and the air absorbing pipeline (2) is provided with a plurality of air absorbing holes (3) communicated with the rooms needing to change air. The fresh air changing system is characterized in that the air absorbing pipeline (2) is provided with at least one multi- air-duct pressure device (4) which is provided with two air ducts, the two ends of which are communicated with the ends corresponding to the air absorbing pipeline (2), and one of the air ducts is equipped with a blower fan (5). The invention solves the problem of installing forced fans on the air absorbing pipeline, can ensure the work of all the forced fans not to affect the air change of other rooms, and selectively pressurizes the rooms needing pressure boost according to the needs, thus ensuring the effect of air change.

Description

technical field [0001] The invention relates to a residential ventilation system, especially a residential fresh air ventilation system that can increase or decrease the ventilation effect according to individual needs, in particular to a residential suite fresh air ventilation system with a dual-channel pressurized exhaust device system. Background technique [0002] As we all know, noise pollution and dust pollution in environmental pollution are becoming more and more serious, which forces people to live with windows often closed. In addition, with the improvement of living standards, air conditioners have become daily necessities. When using air conditioners, the windows must be closed to ensure the effect of heating or cooling, and to prevent the waste of energy in the air conditioning system. In addition, bad weather, winter, no one at home, etc. Windows need to be closed. However, if the windows are closed and the windows are not opened for ventilation, the toxic or...
