▎ 摘　　要

NOVELTY - The system has an exhaust air chamber (6) connected with an air inlet and outlet chamber (8) through a graphene heat exchanger (4). A fresh air inlet chamber (7) is connected with a fresh air outlet chamber (9) through the graphene heat exchanger. An exhaust fan is connected with an external exhaust outlet pipe that is fixed in an exhaust air chamber. A side of the fresh air inlet chamber is provided with a fresh air coarse filter, a sub-efficient filter and an active carbon adsorption layer. A fresh air outlet chamber is provided with a blower that is connected with an external fresh air outlet pipe. A side of a blower is fixed close to the graphene heat exchanger that is provided with an UV sterilizing lamp. USE - Healthy household fresh air system with high efficiency and comfortable sterilizing function. ADVANTAGE - The system has high efficiency and comfortable sterilizing function, and increases negative oxygen ion and energy-saving, automatically adjusts introducing fresh air amount according to air carbon dioxide concentration, harmful chemical gas concentration and air humidity condition, effectively ensures quality of the air, reduces dependence of external environment air, satisfies indoor air changing requirement of people, removes floating dust in the air, sterilizes, humidifies and increases negative oxygen ion, and meets idea requirement of healthy living. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the healthy household fresh air system with high efficiency and comfortable sterilizing function.
