How does a Freightliner air conditioner system work?
Freightliner AC systems are much larger than most vehicle systems, and they use a larger condenser and an air compressor to cool the air. An evaporator is used on freightliner trucks as a heat exchange medium to move the heat generated by the system away from the air conditioning unit.
