Abstract: A blower includes a shaft and a centrifugal fan. The centrifugal fan includes a plurality of blades, a shroud and a main plate. Each of the plurality of blades has a leading edge and a trailing edge. At each blade, a negative pressure surface of an air inlet section of the blade, which is closer to the leading edge than the trailing edge, has a projection that projects toward a positive pressure surface of an adjacent one of the plurality of blades. At least a portion of the positive pressure surface of the air inlet section is inclined toward a forward side in a rotational direction of the centrifugal fan to progressively extend toward the forward side in the rotational direction as the portion of the positive pressure surface of the air inlet section extends toward the main plate.

Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.

Abstract: A vehicle air conditioner includes a casing, a heater core that heats an air flow by heat exchange between the air flow and a heat medium, an electric heater that heats an air flow by an electric power, and a determiner that determines whether a temperature of the heat medium is equal to or lower than a predetermined temperature. When the determiner determines that the temperature of the heat medium is equal to or lower than the predetermined temperature, an air flow introduced into a casing is heated by the electric heater and flows toward the vehicle interior without passing through the heater core.

Abstract: An air discharge device is configured to discharge an air flow. The air discharge device includes a main hole for discharging an air flow as a working air flow, an auxiliary hole provided around the main hole to discharge a support air flow, and a vortex suppression structure configured to suppress development of vortices generated in a velocity boundary layer of the working air flow at a downstream side of an outlet of the main hole. This vortex suppression structure is configured to make a central portion of the thickness of the velocity boundary layer of the working air flow at the downstream side of the outlet of the main hole to be closer to a mainstream of the support air flow, at the downstream side of the outlet of the main hole.

Abstract: A humidification device is used in a vehicle air conditioner having a cooler disposed in an air conditioning case. The air conditioning case has a ventilation path leading air into a vehicle compartment. The humidification device has an adsorber that absorbs and desorbs moisture, a blower, a door that opens or closes an air flow path, and a controller. The controller switches the air flow path by controlling the door to set (i) a dehumidification mode in which air cooled by the cooler is led to the adsorber, and moisture in the air is adsorbed by the adsorber or (ii) a humidification mode in which air is led to the adsorber, the moisture is moved from the adsorber to the air to humidify the air, and the humidified air is blown toward an occupant.

Abstract: An air conditioner for a vehicle includes: a casing; an air blower; and a mode switching portion switching an inlet mode to draw air into the casing and an outlet mode to blow out air to the vehicle interior. The casing has a driver seat inlet port from which air in a space adjacent to a driver seat is drawn in. The mode switching portion is configured to be switchable between a normal mode during which air drawn in from at least one of air inlets is blown out from both of a driver seat outlet and a passenger seat outlet and a driver seat mode during which air drawn in from the driver seat inlet port is blown out from the driver seat outlet. The driver seat inlet port is located in a region exposed to the space adjacent to the driver seat.
