An air conditioner for a vehicle includes a casing, a cooling heat exchanger, a cooling temperature adjusting portion, a dew-point detector, a target temperature determining portion, and a cooling temperature control portion. The cooling heat exchanger is arranged in the casing to cool air to be blown into a vehicle compartment. The cooling temperature adjusting portion adjusts a cooling temperature of air cooled at the cooling heat exchanger such that the cooling temperature approaches a target cooling temperature of the cooling heat exchanger. The dew-point detector detects a dew-point temperature of air flowing to the cooling heat exchanger. The target temperature determining portion determines the target cooling temperature to be a first target temperature lower than the dew-point temperature by a standard degree, and temporarily to be a second target temperature lower than the first target temperature.

Air conditioner for vehicle

A vehicle air conditioner includes a cooling heat exchanger arranged in a casing, a compressor control portion which controls a compressor such that a cooling temperature at the cooling heat exchanger approaches a target cooling temperature, and a dryness determination portion which determines whether an outer surface of the cooing heat exchanger is dry or not based on a humidity in the casing. A target temperature determination portion determines the target cooling temperature to be any one of target temperatures including a first target temperature that is lower than a dew-point temperature in the casing, when the dryness determination portion determines that the cooling heat exchanger is not dry. The target temperature determination portion determines the target cooling temperature to be any one of the target temperatures other than the first target temperature, when the dryness determination portion determines that the cooling heat exchanger is dry.

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.

Vehicular air conditioner

A heating device for a vehicle is provided with a radiation-heat generating unit for generating radiation heat, a first light-distributing unit for converting irradiation directions of the radiation heat into a substantial single irradiation direction, and a second light-distributing unit for distributing the radiation heat to at least one heating object in a passenger compartment of the vehicle. The second light-distributing unit slantways intersects the radiation heat which has the substantial single irradiation direction converted by the first light-distributing unit.
