The present invention relates to an air conditioning system for a railroad vehicle. The system includes: a heating, ventilation, and air conditioning (HVAC) unit including a unit housing, and first and second cooling circuits provided in the unit housing; a first control part formed to operate at least one of the first and second cooling circuits; and a second control part formed to operate at least one of the first and second cooling circuits. The second control part operates at least one of the first and second cooling circuits with priority over the first control part, and the first control part preliminarily operates at least one of the first and second cooling circuits when an abnormality of the second control part occurs. Therefore, the present invention is capable of improving cooling performance by increasing the cooling capacity.
