Introduction To Rear Ac Systems

Rear AC systems keep the back seat cool. Cars with dual-zone or dual-AC allow different temperatures. Each area has its own controls.

Key parts include compressor, condenser, and evaporator. They work together to cool the air. Passenger comfort relies on a working rear AC. Especially for those sitting in the back.

CompressorCirculates refrigerant.
CondenserReleases heat from refrigerant.
EvaporatorCools air inside the vehicle.
