The invention relates to the field of railway vehicles, and provides a sand-discharging and dust-removing air conditioning unit and a railway vehicle. The sand discharging and dust removing air conditioning unit comprises an air conditioner shell, and a condensation cavity and an evaporation cavity are formed in the air conditioner shell. The shell also comprises a fresh air sand removal device, the fresh air sand removal device comprises a fresh air sand removal shell, a sand removal and dust removal box arranged in the fresh air sand removal shell, a sand discharge fan connected with a sandand dust discharge port of the sand removal and dust removal box, and a fresh air fan connected with an air outlet of the sand removal and dust removal box, and a fresh air inlet communicated with anair inlet of the sand removal and dust removal box is formed in one side of the fresh air sand removal shell. A fresh air supply outlet communicated with an air outlet of the fresh air fan is formed in the other side of the fresh air sand removal shell; the fresh air supply outlet is in butt joint with an air inlet of the air conditioner shell and is communicated with the evaporation cavity, a carriage air supply outlet communicated with a carriage is formed in the evaporation cavity, and a secondary filter screen is arranged on a path between the air inlet of the air conditioner shell and thecarriage air supply outlet. The technical problem that sand and dust of an existing railway vehicle air conditioning unit easily enter a passenger room is solved.
