Abstract

The utility model discloses a hidden fresh air ventilation system. An air door capable of being opened is arranged between an air feeder and an exhaust fan, air supply ports are arranged on the periphery of edges of a machine case which is located at the position of the air feeder, a strip-shaped hole is arranged on the machine case on the side of an exhaust outlet of the exhaust fan, and a filter screen is arranged in the strip-shaped hole. Due to the fact that an air supply state and a dedusting state of the fresh air ventilation system can share the same air channel, the hidden fresh air ventilation system is simple, compact and stable and reliable in action. During air supply, the air feeder directly draws outdoor cold air, and the outdoor cold air is sent indoors by the air channel after being filtered by the filter screen. During dedusting, the air feeder stops working, the exhaust fan absorbs all the air coming form the interior of a base station, directly draws out the hot air in the base station and exhausts the hot air outdoors. Therefore, use ratio of the fans is improved, simultaneously dust on the filter screen can be removed, maintenance period is prolonged, frequent changing of the filter screen is avoided, and maintenance cost is reduced. Simultaneously, the air channel is short and smooth in path, thereby reducing loss of air quantity and air pressure.
