Net 3 enters total-heat exchanger 2 and is respectively formed slope air duct before and later, and total-heat exchanger 2 leads to the slope wind in linear air duct
Road increases 1.5~1.6 times, and slope air duct of the wind after total-heat exchanger 2 by the increase, wind speed can be decreased obviously, and not
Whirlpool reflux is easily formed, distinguished and admirable more smooth, wind residence time in total-heat exchanger 2 will increase, and hot and cold air is handed in full heat
The time of 2 self-energy of parallel operation exchange can extend, and be more advantageous to the raising of heat recovery efficiency, and with the decline of wind speed, wind and machine
The coefficient of friction of group inner wall can reduce, and whole noise can be decreased obviously, similarly, the folder between the second inclined plate 6 and return air strainer 4
Angle is b, and b > 0, and details are not described herein.
Specifically, a > b, the air duct for entering air inlet in total-heat exchanger 2 is longer, improves the heat exchange of total-heat exchanger 2
Efficiency, those skilled in the art can the demand according to product to air duct length be configured the first inclined plate 5 and air-supply strainer 3, the
Angle between two inclined plates 6 and return air strainer 4 is not limited to the present embodiment to change the air duct length into total-heat exchanger 2
Embodiment.
Further, the air inlet direction of total-heat exchanger 2 and return air direction are respectively equipped with air inlet inclined plate 21 and return air inclined plate
22, so that air is formed slope air duct in total-heat exchanger after entering total-heat exchanger 2, further decrease wind speed, increases empty
Gas residence time in total-heat exchanger 2, hot and cold air can extend in the time that 2 self-energy of total-heat exchanger exchanges, more have
Conducive to the raising of heat recovery efficiency, and with the decline of wind speed, the inner wall coefficient of friction of wind and total-heat exchanger 2 can reduce, have
Help reduce the noise of equipment entirety.
With reference to Fig. 1, the present embodiment additionally provides a kind of new fan air duct system, and including above-mentioned air channel structure, shell 1 is right
The air supply direction of total-heat exchanger 2 and air draft direction is answered to be respectively equipped with the first arc air duct 11 and the second arc air duct 12, first
The arcwall face in arc air duct 11 is opposite with the air supply direction of total-heat exchanger 2, and the arcwall face in the second arc air duct 12 and full heat are handed over
The air draft direction of parallel operation 2 is opposite.The wind come out from the air supply direction and air draft direction of total-heat exchanger 2 is set to pass through the first arc respectively
It is flowed behind shape air duct 11 and the second arc air duct 12 to certain direction, reflux of being rebuffed will not be generated and form whirlpool, make wind flow
It is more smooth, reduce the noise that air flowing is formed with wall friction in air duct.
Specifically, the first arc air duct 11 and the second arc air duct 12 include straight line portion and curved portion, straight line portion and complete
The air supply direction or air draft direction of heat exchanger 2 are arranged in parallel, the air supply direction or air draft direction of curved portion and total-heat exchanger 2
It is oppositely arranged, the first end of curved portion is tangent with straight line portion, when coming out wind from total-heat exchanger 2, first along straight line portion
Blowout, then cuts curved portion, blows out along the direction of curved portion, and preventing wind, rebuffed rebound reflux is formed in a smaller space
Whirlpool reduces the noise that air flowage friction generates.
Further, the second end of curved portion is equipped with for blowing or the blower 7 of air draft, makes to come out from total-heat exchanger 2
Wind the air inlet position of blower 7 is flow to behind the first arc air duct 11 or the second arc air duct 12, and wind is in the band of blower 7
Higher static pressure can be generated under dynamic, the opposite power consumption that can reduce blower 7 makes blower 7 generate higher efficiency, integrally plays increase
The effect of static pressure.
With reference to Fig. 2, it is covered with noise reducing plate 8 on the first arc air duct 11 and the second arc air duct 12 in the present embodiment,
The noise that air is formed in the first arc air duct 11 or the flowing of the second arc air duct 12 is absorbed by noise reducing plate 8, is further increased
The effect of noise reduction.
It in the present embodiment, further include temperature detecting unit for detecting return air temperature and supply air temperature, temperature detection
Unit is connect with channel switch 14, when temperature detecting unit detects that the difference of return air temperature and supply air temperature is default greater than first
When value, channel switch 14 is opened；

14 close；
First preset value is greater than the second preset value.
Return air temperature and supply air temperature, and then the switch of control channel switch 14 are detected respectively by temperature detecting unit,
To realize when ambient temperature is lower, room temperature is higher, by directly introducing outside air in bypass air duct 13, drop
The temperature of low room air reduces energy consumption.
With reference to Fig. 1 and Fig. 2, channel switch 14 is the valve block that keeps out the wind, and the valve block that keeps out the wind is rotatably disposed in bypass air duct 13, structure
Simply, can make to bypass the connection of air duct 13 by rotation, further, bypass 13 side of air duct is equipped with to be turned over for limiting the valve block that keeps out the wind
The retention bead 15 for turning direction, the valve block that prevents from keeping out the wind are blown open in bypass 13 air flow process of air duct, and raising is kept out the wind valve block
Close the reliability in bypass air duct 13.
To sum up, the present invention keeps the air duct into total-heat exchanger 2 elongated by the first inclined plate 5 of setting and the second inclined plate 6,
Wind speed reduces, and the coefficient of friction of wind and the inner wall of total-heat exchanger 2 can reduce, and declines the noise of equipment entirety, and make air
Residence time is elongated in total-heat exchanger 2, improves the heat recovery efficiency of unit；
In addition, the first arc air duct 11 and the second arc air duct 12 is respectively set in 2 air-out direction of total-heat exchanger, effectively
The noise that air is formed after the blowout of total-heat exchanger 2 is reduced, reduction forms air swirl, and the function of blower 7 can be effectively reduced
Consumption, makes blower 7 generate higher efficiency, integrally plays the role of increasing static pressure；
Finally, being provided with bypass air duct 13, can directly will according to the indoor and outdoor temperature difference, the unlatching of control channel switch 14
Outdoor pure and fresh cool air enters interior by bypassing air duct 13, so that reaching energy-efficient purpose while indoor comfortable.
