Claim:
1. A heating, ventilation, and air conditioning (HVAC) system for a vehicle, said system comprising: a single fan for blowing air in a downstream direction; an evaporator downstream of the single fan and configured to cool air passing through the evaporator; a diffuser configured to direct a first portion of the air blown by the single fan through a first section of the evaporator, and direct a second portion of the air blown by the single fan through a second section of the evaporator, wherein the evaporator and the diffuser are configured to cooperate such that air exits the first section at a first temperature and at a first velocity, and air exits the second section at a second temperature less than the first temperature and at a second velocity; and an upstream valve disposed in the diffuser between the single fan and the evaporator and operable to vary the first velocity relative to the second velocity; wherein the first section of the evaporator is aligned with a first downstream duct directed to spot cool an occupant residing in a cabin of the vehicle, and the second section of the evaporator is aligned with a second duct directed to volume cool the cabin of the vehicle, the system further comprising a movable partition immediately downstream of the evaporator configured for selectively diverting a portion of the air exiting the first section of the evaporator to the second duct.
