[specific embodiment]
Refering to fig. 1, Fig. 2 and Fig. 3, a kind of novel building fresh air system of the utility model, including fresh air air inlet 1, fresh air
Blower 2, fresh air outlet 3, lower exhaust outlet 4, exhaust fan 5, air draft lower transverse tubule 6, air draft isocon 7, air draft standpipe 8, air draft
Header 9, air draft upper outlet 10, air draft upper lateral tube 11, room 12, the first exterior wall 13 and the second exterior wall 14, the room 12 are right
13 top of the first exterior wall of side is provided with fresh air air inlet 1, and fresh-air fan 2 is equipped on the inside of the fresh air air inlet 1, described new
Fresh air outlet 3 is installed, 14 lower part of the second exterior wall in 12 left side of room is arranged in the lower exhaust outlet 4, described on wind blower 2
Lower exhaust outlet 4 is connected with air draft lower transverse tubule 6, and exhaust fan 5, the air draft lower transverse tubule 6 are provided in the air draft lower transverse tubule 6
Lower end inside second exterior wall 14 is set, and the left end of the air draft lower transverse tubule 6 is connected with air draft isocon 7, the air draft
Isocon 7 is connected with the bottom end of several air draft standpipes 8, and the air draft standpipe 8 is arranged inside the second exterior wall 14, the air draft
The top of standpipe 8 is connected with air draft header 9, and the upper end inside the second exterior wall 14 is arranged in the air draft header 9, described
It is communicated with air draft upper lateral tube 11 on air draft header 9, is equipped on the air draft upper lateral tube 11 and is connected with 12 external world of room
Air draft upper outlet 10 is equipped with detachable PM2.5 processing unit in the fresh-air fan 2, and the quantity of the air draft standpipe 8 has
More, the air draft standpipe 8 is uniformly distributed in inside the second exterior wall 14 side by side, the air draft isocon 7, air draft standpipe 8 and row
Wind header 9 is high thermal conductivity pipe, and the exhaust fan 5 and fresh-air fan 2 are speed-changing draught fan, the fresh air air inlet 1, new
The aperture position of wind air outlet 3, lower exhaust outlet 4 and air draft upper outlet 10 is provided with blinds, any one in grid is blocked
Structure.
Outdoor fresh air enters PM2.5 processing unit and fresh air wind under the driving of fresh-air fan 2, by fresh air air inlet 1
Machine 2, by PM2.5 concentration reduce after, by fresh air outlet 3 be sent into room 12 in, indoor exhaust wind under the driving of exhaust fan 5,
Enter air draft isocon 7 from side by the lower exhaust outlet 4 and air draft lower transverse tubule 6 of 14 lower end of the second exterior wall, then flows through one group
Air draft standpipe 8 enters the air draft header 9 on 14 top of the second exterior wall, and in the air draft through being located at 9 other side of air draft header
Transverse tube 11 and air draft upper outlet 10, are discharged into outdoor for indoor exhaust wind.Since air draft lower transverse tubule 6 and air draft upper lateral tube 11 are respectively set
In the side of air draft isocon 7 and the other side of air draft header 9, exhaust pipeline is reversed return type, so that it is vertical to flow through one group of air draft
The air quantity of pipe 8 is balanced.It is empty far below outdoor since summer temperature of outgoing air is indoor air temperature during said exhaust
Temperature degree, therefore the temperature in the outside of the second exterior wall 14 can be reduced, it might even be possible to equal to the temperature of 14 inner surface of the second exterior wall,
This means that the temperature difference that can greatly reduce 14 outside and 14 inner surface of the second exterior wall of the second exterior wall, to reduce or even eliminate
By the second exterior wall 14 from outdoor to indoor heat output, so that space cooling load reduces, air conditioning energy consumption is greatly reduced.Winter
Temperature of outgoing air is indoor air temperature, is much higher than outside air temperature, therefore the temperature in 14 outside of the second exterior wall can be improved,

The temperature difference of inner surface, to reduce or even eliminate through the second exterior wall 14 from interior to outdoor heat output, so that room heat is negative
Lotus reduces, and air-conditioning or heating energy consumption are greatly reduced, and in transition season, room air conditioner is not run with heating, indoor and outdoor air temperature
Spend very nearly the same, indoor exhaust wind is from the point of view of cold (heat) amount, the necessity that has not utilized.This system still can be at this time
The conventional ventilation of row, to improve indoor air quality.
The utility model utilizes the interior of low temperature by the way that air-exhausting duct to be distributed into 14 outside of the second exterior wall, summer in the form of comb
Air draft, to reduce the temperature in 14 outside of the second exterior wall, winter utilizes the indoor exhaust wind of high temperature, 14 outside of the second exterior wall of Lai Tigao
Temperature, reduces or even eliminates the temperature difference of 14 inner and outer of the second exterior wall, to reduce or even eliminate the cold of the second exterior wall 14
(heat) load, in the case where keeping ventilation, energy saving.In transition season, it can still keep normally divulging information and change
Gas.Since exhaust pipeline system uses reversed return system, each available equilibrium of loop air quantity.This system can only be set
PM2.5 processing unit is set, no setting is required, and air-to-air total heat exchanger can still make full use of in the case where not having to air-to-air total heat exchanger
The cooling capacity of Summer Indoor air draft and the heat of winter indoor exhaust wind reduce or even eliminate cold (heat) load of the second exterior wall 14, together
When can also greatly reduce system resistance and blower power consumption, system structure is simple, long service life, and maintenance is simple, significantly
It reduces costs and operating cost, is conducive to promote and apply.
