Provided is a fragrance device for vehicle with an aim to restrain an olfactory adaptation of an occupant, to continuously provide the occupant for a long time with changes in sensory intensity of smell caused by intermittent smell emission, and to provide the occupant for a long time with a relaxation effect due to a smell, the fragrance device for vehicle includes: a fragrance holder holding a fragrance; a blowing means for blowing air to the fragrance holder to blow a smell of the fragrance into a vehicle cabin; and a fragrance blowing control means for sequentially repeating the repeating of a predetermined cycle of blowing a smell of the fragrance and a pause predetermined times by intermittently blowing the smell at each cycle, and then the providing of a stop time for stopping the blowing out of the smell of the fragrance for a predetermined time period.

Fragrance device for vehicle and fragrance blowing method

A cooling and heating air conditioner installed in an electric vehicle, having a cooling and heating air conditioning unit including a cooling device that produces cooled air, and a heating device that produces heated air, wherein the cooling and heating air conditioning unit sends the cooled air produced by the cooling device or the heated air produced by the heating device to a vehicle interior, a cooling and heating air conditioning controller that sets the cooling and heating air conditioning unit to a cooling mode for sending the cooled air produced by the cooling device, a heating mode for sending the heated air produced by the heating device, or an AUTO mode for automatically selecting the cooling mode or the heating mode at least based on a temperature of the vehicle interior so as to control the cooling and heating air conditioning unit according to a set mode.

Cooling and heating air conditioner

A vehicle air-conditioning system has an intake door that switches between an inside air recirculation mode to take in air from an inside air introduction port and an outside air introduction mode to take in air from an outside air introduction port, a blower that blows the air introduced through any of the inside air introduction port and the outside air introduction port toward inside of a vehicle cabin, a heater that heats the air blown by the blower, and a controller that activates the heater when there is a request for heating the inside of the vehicle cabin, controls air conditioning such that an environment inside the vehicle cabin becomes a desired environment by set estimated time of departure.

Vehicle air-conditioning system and vehicle air-conditioning method
