Place.
Sensor includes that air odor sensor is fixedly installed on indoor exhaust wind mouth 32, at least one in indoor return air mouth 22
Place.
The two fans formula intelligent fresh air system of the present embodiment has following several operating modes:
(1) conventional air draft mode of blowing, return air inlet in the first stepper motor sealing chamber open outdoor air inlet, wind of blowing
Outdoor air is sent into indoor, then exhaust fan starting by machine starting by indoor air outlet, by room air from indoor exhaust wind
Mouth passes through outdoor exhaust outlet after introducing and is discharged.
This mode, which is mainly used in after fresh air system shuts down the long period, restarts；Or in summer, outdoor temperature is lower than
For cooling down when indoor set temperature.
(2) interior circulation pattern, the first stepper motor close outdoor air inlet, open indoor return air mouth, and exhaust fan is minimum
Shelves starting, then breeze fan starts, and room air is introduced from indoor return air mouth, successively after three filter layers purify,
It is sent out again from indoor air outlet.
This mode is recycled by inside under the premise of air is clean indoors, and room air is avoided to flow out and outdoor air
It flows into, is in room air and circulates, and stablize indoor air quality within the scope of setup parameter.
(3) independent air supply pattern, return air inlet in the first stepper motor sealing chamber open outdoor air inlet, and exhaust fan is most
Small shelves starting, then breeze fan starting introduces outdoor air from outdoor air inlet, then sends out from indoor air outlet.
Slave pattern is suitable for the case where indoor carbon dioxide concentration, VOC (volatile organic matter) concentration over-standard, passes through introducing
Outdoor fresh air effectively dilutes the concentration of carbon dioxide and VOC.
Meanwhile exhaust fan minimum shelves start, and the air of indoor lower temperature or higher temperature is avoided largely to flow to room
Outside, energy waste is caused.
(4) individually air draft mode, breeze fan are closed, and exhaust fan starting, second stepper motor is all turned on indoor row
Air port so that after room air is introduced via indoor exhaust wind mouth, then is discharged by outdoor exhaust outlet.
This mode can be used for depression dust-removing；Meanwhile indoor exhaust wind mouth is normally placed in toilet, accordingly it is also possible to
For excluding indoor peculiar smell, or the hot gas generated when exclusion summer bathing when indoor/outdoor temperature-difference is excessive.
(5) interior tape loop air draft mode, the first stepper motor closing outdoor air inlet, opening indoor return air mouth, and heel row
Wind blower, breeze fan starting introduce room air from indoor return air mouth, successively after three filter layers purify, one
Divide and sent out from indoor air outlet, another part passes through outdoor exhaust outlet and is discharged.
The case where it is not exceeded that this mode is mainly used in summer indoor air quality, but there are peculiar smell for interior, due to summer
Room temperature is low, and outdoor temperature is high, this mode can be while removing odors, and reduction energy consumption as far as possible is energy saving.
To sum up, the two fans formula intelligent fresh air system of the present embodiment can pass through above five kinds of operating modes.Pass through sensing
The collected room temperature of device, outdoor temperature, indoor air quality and room air smell, then feed back to controller, then by
Controller controls the operation of breeze fan 2, exhaust fan 3, the first stepper motor 5, second stepper motor 6, and intelligence adjusts fresh air
The operating mode of unit promotes indoor air quality to change indoor air temperature, and discharge has odorous room air,
To meet work, the life requirement of user.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement, which is both fallen within, to be required in the scope of protection of present invention.The scope of protection of present invention by appended claims and
