1. A vehicular air conditioner for a vehicle, the vehicular air conditioner comprising:
- an air-conditioning unit that has a plurality of outlets corresponding to a driver'"'"'s seat and any other seats in the vehicle and that blows air-conditioned air from the outlets to the driver'"'"'s seat and the any other seats;
a blower that is accommodated in the air-conditioning unit and that is driven by an electric motor to generate blown air;
a switching section provided in the air-conditioning unit for switching between a normal air-conditioning mode, in which the air-conditioned air is blown from a driver'"'"'s seat outlet corresponding to the driver'"'"'s seat and the any other outlets corresponding to the any other seats other than the driver'"'"'s seat, and a single seat concentration mode, in which the blowing of the air-conditioned air from at least one of the any other outlets is prohibited and the air-conditioned air is blown solely from the driver'"'"'s seat outlet; and
a controller configured to control the operation of the switching section and to control the amount of the air blown by the blower by setting a supplied power to the blower in accordance with an air-conditioning heat load, whereinthe controller is configured to execute the normal air-conditioning mode when an occupant is seated in any seat other than the driver'"'"'s seat,the controller is configured to execute the single seat concentration mode when there is no occupant in the seats other than the driver'"'"'s seat, andthe controller is configured to set the supplied power to the blower in the single seat concentration mode to be smaller than in the normal air-conditioning mode at any given air-conditioning heat load.

Abstract
When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.

8. A vehicular air conditioner for a vehicle, the vehicular air conditioner comprising:
-
an air-conditioning unit that has a plurality of outlets corresponding to a driver'"'"'s seat and any other seats in the vehicle and that blows air-conditioned air from the outlets to the driver'"'"'s seat and the any other seats; a switching section provided in the air-conditioning unit for switching between a normal air-conditioning mode, in which the air-conditioned air is blown from a driver'"'"'s seat outlet corresponding to the driver'"'"'s seat and the any other outlets corresponding to the any other seats other than the driver'"'"'s seat, and a single seat concentration mode, in which the blowing of the air-conditioned air from at least one of the any other outlets is prohibited and the air-conditioned air is blown solely from the driver'"'"'s seat outlet; a heating heat exchanger that is provided in the air-conditioning unit and that heats the blown air heading to an inside of a vehicle compartment of the vehicle by using a cooling fluid, the cooling fluid cooling a drive unit used for obtaining a driving force for running the vehicle, as a heat source; and a controller configured to control operation of the switching section and to request an operation of the drive unit when a temperature of the cooling fluid is lower than a predetermined temperature, wherein the controller is configured to execute the normal air-conditioning mode when there is an occupant in any of the any other seats other than the driver'"'"'s seat, the controller is configured to execute the single seat concentration mode when there is no occupant in any of the any other seats other than the driver'"'"'s seat, the controller is configured to set the predetermined temperature based on an air-conditioning heat load, and the controller is configured to set the predetermined temperature in the single seat concentration mode to be lower than in the normal air-conditioning mode at any given air-conditioning heat load.
