The invention relates to a multifunctional fresh air intelligent window, including a window frame, window leaves, a full heat-exchange ventilator, a panel. The window leaves and the full heat-exchange ventilator are respectively fixed in the window frame. The panel is fixed at the outside of the full heat-exchange ventilator. Glass is fixed in the window leaf. A window lock is set on the window leaf frame. The full heat-exchange ventilator includes an outdoor fresh air port, an indoor fresh air port, a fresh air blower, an exhaust blower, an exhaust filter, a fresh air filter, a full heat exchanger, a receiving controller, an outdoor exhaust outlet and an outdoor air inlet. The fresh air blower and the exhaust blower are respectively fixed in the fresh air blower scroll casing and the exhaust scroll casing. A motor is respectively connected with the fresh air blower and the exhaust blower. The multifunctional controller controls the motor. The fresh air blower scroll casing and the exhaust scroll casing are connected at the outdoor air inlet and the outdoor exhaust port respectively through the maintenance-free closed full heat exchanger, the fresh air filter and the exhaust filter. The structure is reasonable, high efficient, energy-saving and environment-friendly, integrates optics, mechanics, electricity, communication, monitor and protection, ventilates and exchange air, recycles temperature and humidity, sterilizes and remove abnormal taste in the air through the fresh air filter, generates negative ion and increase oxygen.
