Abstract
A vehicle air conditioning system includes an air handler and a controller. The air handler defines a fresh air inlet, air outlets that directs air into a passenger compartment and a recirculation inlet that draws air from the passenger compartment into the air handler. The air handler operates in a fresh air mode and a recirculation mode. In the fresh air mode fresh air enters the air handler through the fresh air inlet and in the recirculation mode fresh air is prevented from entering the air handler, and instead air enters the air handler via the recirculation inlet. The controller switches the air handler to operate in the recirculation mode in response to determining the following: a diesel engine is operating in a regeneration mode and the air handler is in the fresh air mode.
