The invention relates to an energy-saving
system device for
fresh air, and relates to the field of electrical technology. The energy-saving
system device comprises a main
control unit module, an air inlet
system module, an exhaust system module, a temperature and
humidity control module, a key setting module, a status display module, a
power module, a power-off protection module, a self-
recovery function module and a communication function module. The air inlet system module, the exhaust system module, the temperature and
humidity control module, the key setting module, the status display module, the
power module, the power-off protection module, the self-
recovery function module and the communication function module are respectively connected with the main
control unit module. Therefore, the formed energy-saving system device for
fresh air with various functions of control, indication and integration is capable of replacing existing
air exchange fans, negative-
ion generators or
air purifiers, household central air conditioners, large-
tonnage central air conditioners.
