Operation principle of the present invention is as follows:
When indoor/outdoor temperature-difference is larger, new wind and return air is needed to carry out heat exchange, central processing unit 21 controls new wind bypass air-valve 11, return air bypass air-valve 12 and air draft bypass air-valve 13 and cuts out, like this, new wind passes through a passage of new wind passage 1 and heat exchanger 10 successively, flow into air mixing channel 8 by the new wind entrance of air mixing channel 8, enter air-supply passage 2 by the air outlet of air mixing channel 8 again through air mixing channel 8, finally send into indoor from the air outlet of air-supply passage 2.Indoor wind enters air exhaust passage 4 through another passage of return air channel 3 and heat exchanger 10 successively, and is discharged to outdoor by air exhaust passage 4.Like this, new wind and air draft carry out heat exchange through over-heat-exchanger 10 simultaneously, achieve the temperature-compensating of air draft to new wind, make to enter indoor new wind and reduce with the indoor temperature difference, thus the balance breaking indoor temperature is avoided as far as possible when changing wind, reduce the additional compensation of indoor temperature.
When indoor/outdoor temperature-difference very large and return air and the temperature of new wind after recuperation of heat (i.e. temperature of outgoing air) are lower than the second desired temperature, in order to prevent occurring frosting blocking channel in heat exchanger 10, return air bypass air-valve 12 and air draft bypass air-valve 13 can be closed, new wind bypass air-valve 11 is opened in stepping, until temperature of outgoing air is not less than 5 DEG C.Like this, new wind is by new wind passage 1, the new wind of a part enters the new wind entrance of air mixing channel 8 through new wind bypass passageways 7, the new wind of another part enters the new wind entrance of air mixing channel 8 through a passage of over-heat-exchanger 10, there is no the new wind of heat exchange and new wind combined balance system temperature difference in air mixing channel 8 of heat exchange, flow into air-supply passage 2 by the air outlet of air mixing channel 8 again, be finally back to indoor from the air outlet of air-supply passage 2.Indoor wind enters air exhaust passage 4 through another passage of return air channel 3, heat exchanger 10, and is discharged to outdoor by air exhaust passage 4.Like this, new wind and air draft, simultaneously through over-heat-exchanger 10, achieve the temperature-compensating of air draft to new wind, make to enter indoor new wind and reduce with the indoor temperature difference, thus avoid the balance breaking indoor temperature when changing wind as far as possible, reduce the additional compensation of indoor temperature.Meanwhile, also reduce the resh air requirement carrying out heat exchange with return air, prevent the passage frosting of heat exchanger 10 from blocking.
When the temperature difference of indoor and outdoor is very little, new wind and air draft will not need to carry out heat exchange, can open new wind bypass air-valve 11 and air draft bypass air-valve 13, close return air bypass air-valve 12.The resistance that the resistance ratios flowed in new wind bypass passageways 7 due to new wind flows in heat exchanger 10 is much little, so new wind flows into air mixing channel 8 by by new wind bypass passageways 7 through the new wind entrance of air mixing channel 8, flow into air-supply passage 2 from the air outlet of air mixing channel 8, finally flow into indoor from the air outlet of air-supply passage 2.Return air in return air channel 3 flows into air exhaust passage 4 through air draft bypass passageways 9, through air exhaust passage 4 discharged to outdoor, so just reaches the object of directly ventilation.
When needs return air refluxes, the open angle of return air bypass air-valve 12 can be regulated to regulate the capacity of returns of return air, the resistance that the resistance ratios flowed in air mixing channel 8 due to return air flows in heat exchanger 10 and air draft bypass passageways 9 is much little, so the return air inlet by air mixing channel 8 to enter in air mixing channel 8 and mixes with new wind by part return air, flow into air-supply passage 2 from the air outlet of air mixing channel 8 again, finally flow into indoor from the air outlet of air-supply passage 2.New wind bypass air-valve 11 and air draft bypass air-valve 13 carry out corresponding switch-mode regulation according to above three kinds of working conditions.

K4 and the second desired temperature and the 3rd desired temperature compare by step 4, central processing unit (21), and described second desired temperature is less than described 3rd desired temperature; When K4 is lower than the second desired temperature, central processing unit (21) transmits control signal to new wind bypass air-valve (11), its stepping is opened until K4 is not less than the second desired temperature, simultaneously central processing unit (21) transmits control signal and to air draft bypass air-valve (13), air draft bypass air-valve (13) cuts out, execution step 5 after completing; When K4 is not less than the second desired temperature and K4 is less than the 3rd desired temperature, central processing unit (21) transmits control signal and makes it keep present situation to new wind bypass air-valve (11), central processing unit (21) transmits control signal to air draft bypass air-valve (13) simultaneously, described air draft bypass air-valve (13) is closed, execution step 5 after completing; When K4 is not less than the 3rd desired temperature, central processing unit (21) transmits control signal respectively to described new wind bypass air-valve (11) and air draft bypass air-valve (13), makes it close, execution step 5 after completing;
The return air qualitative data Q detected is sent to central processing unit (21) by step 5, air quality sensor (19), central processing unit (21) compares Q and whether exceedes air quality threshold, when Q exceedes air quality threshold, central processing unit (21) transmits control signal to pressure fan (6) and exhaust blower (5) respectively, the motor of described pressure fan (6) and exhaust blower (5) is accelerated, execution step 6 after completing; When Q does not exceed air quality threshold, perform step 6;
Step 6, judge whether central processing unit (21) receives END instruction; When central processing unit (21) receives END instruction, clean wind terminates; When central processing unit (21) does not receive END instruction, return and perform step one.
2. clean new wind method as claimed in claim 1, it is characterized in that: in described air-supply passage (2), be provided with negative oxygen ion generator (14) and inferior high efficiency filter (15), wherein inferior high efficiency filter (15) is near the air outlet of air-supply passage (2), and described negative oxygen ion generator (14) is positioned at the upstream of pressure fan (6); The control signal input of described negative oxygen ion generator (14) connects the 5th output of described central processing unit (21).
3. clean new wind method as claimed in claim 1, is characterized in that: the air outlet place of described air mixing channel (8) is provided with electronic purifier (16); The control signal input of described electronic purifier (16) connects the 6th output of described central processing unit (21).
4. clean new wind method as claimed in claim 1, it is characterized in that: in described new wind passage (1), be provided with roughing efficiency air filter (17), this roughing efficiency air filter (17) is positioned between air inlet and new air temperature sensor (18).
5. clean wind method as claimed in claim 1, is characterized in that: described central processing unit (21) is also connected with electronic purifier (16); When central processing unit (21) receives enabled instruction, central processing unit (21) transmits control signal and makes it start working to described electronic purifier (16).
6. clean wind method as claimed in claim 1, is characterized in that: described central processing unit (21) is also connected with negative oxygen ion generator (14); When central processing unit (21) receives enabled instruction, central processing unit (21) also transmits control signal and makes it start working to described negative oxygen ion generator (14).
