Abstract:
1. A two-layer inside/outside air vehicular air-conditioning system comprising: (a) an air-conditioning case formed at one end side with inside air intake ports and a plurality of outside air intake ports and formed at the other end side with compartment-side air discharge ports; (b) partitioning members which partition the inside of the air-conditioning case into each of a first air passage which connects said inside air intake port to the compartment-side air discharge ports and of a second air passage which connects said outside air intake port to the compartment-side air discharge ports; (c) two means for generating air flow of air inside said air-conditioning case, said two air flow generating means arranged coaxially and connected to a single motor; (d) air-conditioning-use heat exchangers which heat or cool the air which flows through the inside of said first air passage and the air which flows through the inside of said second air passage; (e) means for switching between a two-layer inside/outside mode which introduces compartment air from said inside air intake port to said first air passage and which introduces outside air from an outside air intake port to said second air passage and an outside air introduction mode which introduces outside air from said outside air intake ports to said first air passage and said second air passage; (f) means for opening and closing said compartment-side air discharge ports; and, (g) an air exhaust controller for using one of said outside air intake ports as an air exhaust port, for using said opening and closing means to substantially close all of said compartment-side air discharge ports, and for operating one of said air flow generating means while not operating the other of said air flow generating means so as to cause the air inside of said first air passage and said second air passage to be exhausted from said air exhaust port; wherein the switching means are arranged between one of said air flow generating means and the other of said air flow generating means for switching between connection and disconnection of said two air flow generating means.
