VEHICLE AIR CONDITIONING SYSTEM

A vehicle air conditioning system is provided. The vehicle air conditioning system includes: an air conditioning unit, including a blower and a temperature control module; and a dehumidification device, disposed between the blower and an evaporator of the temperature control module, enabling a part of air conditioning air flowing in from the blower to flow into the dehumidification device, and including an air volume adjusting mechanism for forming an air inflow channel of the dehumidification device; an air path switching mechanism for forming an air discharge channel of the dehumidification device; and a dehumidification element disposed on a flow path of the part of the air conditioning air flowing in from the blower between the air volume adjusting mechanism and the air path switching mechanism. The air volume adjusting mechanism and the air path switching mechanism both include a damper structure configured to adjust a degree of opening.
