An air discharge device includes a duct that defines a flow passage through which a working air flow to be discharged passes, and a hole forming member defining an air discharge hole as an outlet of the working air flow. The hole forming member has a vortex generation structure configured to generate an auxiliary vortex having a vortex characteristic including a vortex rotation direction and a vortex axis direction. The vortex characteristic of the auxiliary vortex is different from that of a lateral vortex generated by the working air flow at a downstream side of the air discharge hole. The vortex generation structure is configured in the hole forming member so that the auxiliary vortex collides with the lateral vortex in a state where at least one of the vortex rotation direction and the vortex axial direction of the vortex characteristic is different from that of the lateral vortex.

Air discharge device

An air discharge device includes an air discharge unit for discharging an air flow. The air discharge unit includes at least one main hole from which an air flow is blown out as a working air flow, and a separation structure configured to separate a central portion of a thickness of a velocity boundary layer of the working air flow from a center line of the main hole at a downstream side of the main hole.

A fluid discharge device is for discharging a fluid includes a duct defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage. The fluid discharge device includes a grill portion disposed in the fluid flow passage to adjust a flow direction of the fluid blown from the opening. The grill portion includes at least an adjustment fin rotatably arranged in the fluid flow passage, and is provided with an auxiliary flow passage that guides a part of the fluid flowing through the fluid flow passage to the opening as an auxiliary flow. The auxiliary flow passage is configured together with the adjustment fin to adjust a flow direction of the auxiliary flow discharged from the auxiliary flow passage to be aligned with the flow direction of the fluid flowing through the fluid flow passage.

Fluid discharge device

The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

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.

A fluid discharge device includes a base portion defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage, and a grill portion disposed to adjust a flow direction of the fluid blown from the opening. The grill portion includes a flow passage forming body defining a main flow passage and an auxiliary flow passage. In the flow passage forming body, the auxiliary flow passage surrounds the main flow passage and the auxiliary flow discharged from the auxiliary flow passage flows outside of the main flow discharged from the main flow passage. The flow passage forming body is configured such that a direction of the auxiliary flow discharged from the auxiliary flow passage corresponds to the direction of the main flow discharged from the main flow passage, when the flow direction of the fluid blown out of the opening is adjusted.

A humidifying device has an adsorption module and a blower. The adsorption module has the adsorbent. The adsorption module is configured to adsorb the water from the air passing through the adsorption module to the adsorbent and is configured to desorb the water from the adsorbent to air passing through the adsorption module. The blower blows the air to the adsorption module. The blower, in an adsorption operation in which the adsorbent adsorbs the water from air, draws the air from a roof space and blows the air to the adsorption module whereby the adsorption module adsorbs the water from the air. The roof space is defined between a vehicle ceiling panel and a ceiling interior member.

Humidifying device

A humidifying device for a vehicle has a humidity detection part, a blower, a non-water-supply humidifier, and a controller. The humidity detection part detects a humidity in a vehicle compartment. The blower draws, as an intake air, an inside air in the vehicle compartment and an outside air outside the vehicle compartment at a specified ratio and blows the intake air toward the vehicle compartment. The non-water-supply humidifier collects water included in the inside air and supplies a humidified air, which is humidified using the water, toward a specified area in the vehicle compartment. The controller sets the specified ratio between the inside air and the outside air and controls an operation of the non-water-supply humidifier. The controller controls the blower to draw at least the inside air, when the non-water-supply humidifier is operated, and when a humidity in the vehicle compartment is lower than a specified humidity.

Humidifying device for vehicle

A humidifier supplies humidified air, which is humidified by water desorbed from an adsorbing material, to a humidification object space. The humidifier includes: a heating part that heats air, which is supplied to the adsorbing material; an adsorbing material module that includes the adsorbing material and that desorbs water, which is adsorbed in the adsorbing material, to air heated by the heating part; and a cooling part that cools air humidified by the adsorbing material module. At time of desorption to desorb water from the adsorbing material, the adsorbing material module desorbs water from the adsorbing material to air heated by the heating part, and then the cooling part cools the air to be supplied to the humidification object space as the humidified air. At time of adsorption to adsorb water of air into the adsorbing material, the cooling part cools air, and then water is adsorbed into the adsorbing material.

Humidifier

In an adsorption operation in which the adsorption agent adsorbs water, air in a vehicle compartment flows into an adsorption agent module after being cooled by passing around a heat sink. On the other hand, in a desorption operation in which the water is desorbed from the adsorption agent, the air in the vehicle compartment flows into the adsorption agent module to be humidified without being heated or cooled, and humidified air is cooled by passing around the heat sink and blown into the vehicle compartment. Accordingly, a temperature of the humidified air can be prevented from increasing unnecessarily by a simple configuration with which the air in the vehicle compartment is cooled in the heat sink.

Humidification device

An air conditioning system for a vehicle includes a heat exchanger, a case clamping an outer peripheral part of the heat exchanger in its thickness direction, and an elastic body disposed at the outer peripheral part of the heat exchanger between the case and the heat exchange. The opposite side of the exchanger is held directly by the case. The elastic body is compressively deformed between the case and the heat exchanger to clamp the heat exchanger. A region of the outer peripheral part of the exchanger includes a planar portion at least on one side of the exchanger. The case includes an air stop rib at a position of the case opposed to the planar portion in the thickness direction of the exchanger. The air stop rib is located adjacent to the planar portion to limit an air leak.
