Description

technical field [0001] The invention belongs to the technical field of fresh air systems, and in particular relates to a room fresh air system with an electric damper and a whole house fresh air system. Background technique [0002] We spend most of our lives in houses, essentially living in the indoor secondary air environment enclosed by the walls and floors of the house; carbon dioxide and excrement produced by human metabolism, oil smoke and water vapor discharged from cooking and bathing, Benzene and formaldehyde, etc., which are volatilized from interior decoration materials, lead to indoor air pollution. [0003] It is the original meaning of home life to introduce fresh air from the outside of the house into the house and discharge the indoor dirty air synchronously, so as to realize the "two-way flow" fresh air replacement of the house. [0004] To solve the ventilation problem of multiple closed spaces such as living room, bedroom, study, bathroom, etc., which are...
