The system includes a controller that determines a minimum voltage to be supplied to the rear blower to prevent an inverse air flow from being expelled from the rear outlet and/or a rear blower air intake. A voltage supplied to the rear blower is then set as the greater of the minimum rear blower voltage and a current rear blower voltage. The inverse air flow is air flow in the front HVAC portion generated by the front blower and intended for the front vent outlet that seeps into the rear HVAC portion and is expelled from the rear vent outlet and/or the rear blower air intake.

Abstract: A cooling storage evaporator system employs a pivoting frost control door upstream from an evaporator that, when closed, inhibits air from passing through a lower portion of the evaporator. Closing the frost control door results in condensed water freezing on a lower portion of the evaporator when the AC is ON. When a vehicle engine is turned OFF when the vehicle stops in an idle condition, thereby turning the compressor OFF, the frost control door opens so that air passes over the evaporator, including the frozen portion thereof, melting the frozen condensed water to maintain the cool outlet air temperature at the vent.
