Because indoor temperature and humidity reaches default suitable degree, the humiture of the waste gas discharged by exhaust fan unit 2 and room
Interior suitable humiture is closer to, and by secondary return air, effectively using indoor temperature and humidity, reduces the inlet of outdoor fresh air, or
Realize the circulation of room air, reduce due to the humiture of outdoor fresh air it is excessive with the difference of default humiture caused by the energy
Waste, correspondingly improve exhaust fan unit 2, the nuisance such as amine, nitrogen fully gone in removing exhaust gas by the improvement for washing spray section 22
Matter, to reach the requirement that return air is utilized.
2nd, use of the above-mentioned energy-saving air processing system with secondary return air under different new wind environments：
Because the temperature and humidity of different regions, the outdoor fresh air of Various Seasonal has very big difference, by default interior
Required temperature, fresh air humiture that master controller can be monitored according to the first temperature sensor and the first humidity sensor with
Preset value is compared, the valve of each segment body of Intelligent adjustment and the frequency of the compressor 31 of outer machine 3；
1) by taking the outdoor fresh air of winter low temperature low humidity as an example：
Assuming that the humiture of outdoor fresh air is less than preset value, therefore master controller controls the compressor 31 of outer machine 3 to close,
So as to evaporator section 14 does not work；Because the Surface cooling coil in surface cooling section 16 connects central air conditioner system, by central air conditioner system
Other mode of heatings such as electrical heating in the heating combination auxiliary bringing-up section 17 of surface cooling section 16 are heated to fresh air, master controller
Correspondingly control the first electric T-shaped valve, the second electric T-shaped valve and proportional electrovalve pre- to reach to control heat exchanger effectiveness
If temperature, and control humidifier section to humidify fresh air by master controller, to reach suitable humidity；
2) by taking the outdoor fresh air of summer high temperature high humidity as an example：
Assuming that the humiture of outdoor fresh air is less than preset value, therefore the TEMP that master controller is set according to fresh air section
The humiture that device and humidity sensor are monitored adjusts the frequency of the outer compressor 31 of machine 3 with the difference of preset value, so that by steaming
Hair 14 pairs of fresh airs of section dehumidify, and dehumidification process, new air temperature is greatly reduced, then correspondingly controls first by master controller
Electric T-shaped valve, the second electric T-shaped valve and proportional electrovalve to control heat exchanger effectiveness, so as to reach suitable temperature, this
When master controller control humidifier section close, without being humidified to fresh air.
3) in case of outdoor fresh air temperature is 36 DEG C：

Pipe flow to the cistern of the bottom of evaporator section 14, and 12 DEG C are down to by the new air temperature after the dehumidifying of evaporator section 14；
Second circulation exhausting section 15 is continued flow through by the fresh air after the dehumidifying of evaporator section 14, now second circulation reclaims coil pipe
At 21-23 DEG C, by after heat exchange, the temperature that second circulation reclaims the port of export of coil pipe 151 is down to 17- to the temperature of 151 entrance points
21 DEG C, and fresh air rises to 17 DEG C by temperature after the section；
Continue to flow to surface cooling section 16 by the fresh air after second circulation exhausting section 15, surface cooling section 16 is by master controller control
Proportional electrovalve, to control the temperature of surface cooling section 16, so as to carry out heat exchange with corresponding fresh air, to reach suitable new wind-warm syndrome
Degree；
Auxiliary bringing-up section 17 and condensing units section 18, condensing units disk are continued flow through by the fresh air after surface cooling section 16
The high-pressure refrigerant after being compressed by compressor 31 is accessed in pipe 181, due to refrigerant compression heat release, with higher temperature, is entered
Fresh air in condensing units coil pipe 181 with this section carries out heat exchange, the supercooling fresh air by dehumidifying is heated, to reach
The suitable temperature in room, to meet the temperature requirements of part room needs, in auxiliary bringing-up section 17 using electrical heating or other add
Hot mode carries out auxiliary heating to fresh air, further controls new air temperature；
Enter room after the fresh air after heating continues flow through air intake medium efficiency filtration section 19 and other segment bodies；
The waste gas discharged by room enters exhaust fan unit 2, passes sequentially through initial effect filtering section and washing spray section 22, it is assumed that warp
The EGT crossed after washing spray section 22 is at 18-21 DEG C；
