Vehicle air conditioning system

A vehicle air conditioning system, comprising:

• an air conditioning unit, configured to adjust temperature in a vehicle compartment and comprising a blower and a temperature control module;
• and
• a dehumidification device, configured to adjust humidity in the vehicle compartment, disposed between the blower and an evaporator of the temperature control module, and enabling a part of air conditioning air flowing in from the blower to flow into the dehumidification device, and the dehumidification device comprising:
• an air volume adjusting mechanism, used to form an air inflow channel of the dehumidification device;
• an air path switching mechanism, used to form 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,
• wherein the air volume adjusting mechanism and the air path switching mechanism both comprise a damper structure configured to adjust a degree of opening, and during an operating process of the dehumidification device, the dehumidification device controls the degrees of opening of the damper structures of the air volume adjusting mechanism and the air path switching mechanism, so that the part of the air conditioning air passing through the dehumidification device is kept constant.
