Abstract: In a vehicular air conditioning apparatus, a connection duct connects a first blower unit having a first blower fan to a side of a casing forming air passages, whereas a second blower unit having a second blower fan, different from the first blower unit, is connected to a lower portion of the casing. By driving the first blower fan and second blower fan simultaneously, air is supplied to a vehicle compartment from the first blower unit and the second blower unit through inside the casing. A controller controls the driving of the first blower fan and the second blower fan.

Abstract: In a vehicular air conditioning apparatus, a first blower unit is connected by a connection duct to a side portion of a casing constituted by respective air passages. On a lower portion of the casing, the first blower unit is connected together with a second blower unit. As a result of a controller controlling driving of an ventilation switching damper, based on a load voltage to a second blower fan of the second blower unit, a first front passage and a first rear passage are placed in communication, whereby a portion of the air from the first blower unit passes through the first front passage, a communication opening, and the first rear passage, and is supplied to a second cooling section of an evaporator, such that when the second blower fan is rotated at a low speed, freezing of water droplets in the second cooling section is avoided.
