Abstract: A droplet-blocking air conditioning system inside a train compartment according to an exemplary embodiment may include an air conditioning system unit for regulating the temperature and humidity of the air inside the train compartment; an air supply regulation unit which uses downdraft air to supply the compartment with the air that has had the temperature and humidity regulated by the air conditioning system unit, thereby causing the droplets remaining in the compartment to flow below the compartment due to the downdraft air; mechanical and electronic motors which control a degree of rotation of the air adjustment member according to the degree of rotation of a rotary shaft inside the air supply regulation unit; and an air discharge unit for discharging the droplets and the downdraft air to the outside of the compartment.
