An air conditioner damper is a device used to control the flow of air within a ventilation system. It is typically used to regulate the temperature of a room or building by allowing more or less air to flow through the system. The damper is typically a metal plate or valve that is opened or closed by a motor or manually. When the damper is open, air is allowed to flow freely through the system. When the damper is closed, air is restricted and the temperature of the room or building is regulated. The air conditioner damper is an important component of a ventilation system as it allows for precise control of the temperature of a room or building. It is also used to regulate the humidity of a room or building by controlling the amount of air that is allowed to pass through the system.
