HVAC dehumidification system

An air intake system for a vehicle HVAC system, comprising:

• a housing comprising an air inlet, a dehumidification component, a valve disposed downstream of the dehumidification component, a first outlet and a second outlet disposed to receive air that has flowed past the dehumidification component, wherein the first outlet is aligned to direct air flowing therethrough toward a downstream fan that provides air flow within a vehicle HVAC system and ultimately to a passenger compartment for the vehicle, and the second outlet is aligned to direct air flowing therethrough out of the vehicle and not into the passenger compartment;
• wherein the dehumidification component configured to receive electric current during operation;
• wherein the dehumidification component includes a plurality of separate zones, with each zone being capable of providing dehumidification of air that flows therethrough when energized and providing insignificant dehumidification when not energized;
• and
• wherein the valve is positioned to block air from flowing past the one or more zones of the dehumidification component that are not desired for dehumidification.
