An air conditioner for a vehicle may include a first air conditioner provided on the engine compartment side with respect to a dash panel, and including an intake unit of suctioning internal or external air and blowing same to the vehicle interior side; and a second air conditioner provided on the vehicle interior side with respect to the dash panel, and including a duct for discharging conditioned air to the vehicle interior side. The dash panel has a through hole formed therein, and has an air guide which connects the first air conditioner and the second air conditioner to each other through the through hole.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.

A cab for a construction machine includes: a specified side wall having a side window frame defining a side window and at least one side transparent plate supported by the side window frame; an air conditioner unit having an air conditioner outlet hole; a side beam extending in a front-rear direction along the specified side wall and below the side window frame; and a side duct located above the side beam, extending in the front-rear direction along a lower section of the side window frame, and receiving at least a part of the air blown out from the air conditioner unit, the side duct having at least one side duct vent for blowing out the air toward the at least one side transparent plate.

A vehicle includes a steering column connected to a steering wheel, a column cover that covers the steering column, and an air duct that is disposed inside an instrument panel and passes in front of the column cover. Buckling strength of the air duct in a vehicle body front-rear direction in front of the steering wheel is lower than buckling strength of the column cover in the vehicle body front-rear direction.

A vehicle includes an instrument panel reinforcement that extends in a vehicle width direction inside an instrument panel, a steering wheel located behind the instrument panel reinforcement, and an air duct that is disposed inside the instrument panel and passes between the instrument panel reinforcement and the steering wheel.

This disclosure provides an engineering vehicle and an air conditioning system thereof beneficial to improve comfortability of drivers. The air conditioning system includes: an air conditioner body, including a shell with first and second air outlet; a first air supply pipeline, a first end of the first air supply pipeline being connected to the first air outlet; first air support port(s), arranged at an inner front end of a cab of the engineering vehicle and connected to a second end of the first air supply pipeline; a second air supply pipeline, a first end of the second air supply pipeline being connected to the second air outlet; second air supply port(s), arranged at an inner rear end of the cab and connected to a second end of the second air supply pipeline; and a flow distribution device including a flow dividing portion located in the shell.

A fluid distribution door for an air-handling system of a heating, ventilating, and air conditioning system includes an air-directing wall having a first major surface and an oppositely arranged second major surface, a bleed port projecting from the second major surface of the air-directing wall, and a bleed path formed through the fluid distribution door. The bleed path extends through the air-directing wall and the bleed port.

A vehicle air conditioner is disclosed. The present invention provides the vehicle air conditioner, which: can directly control the amount of air passing through an evaporator and a heater core since a blower is disposed between the evaporator and the heater core; has front and rear seat discharge units respectively having heater cores, thereby having a simple form, minimizing energy consumption, and independently enabling four or more zones, including front and rear seats, the left and right of the front seats, and the left and right of the rear seats, to be air-conditioned; and can discharge an offensive smell to the outside during initial driving of a vehicle since the air outside a vehicle, flowing in from an air inlet, and indoor air flowing in from an inside air suction port, disposed at the center of the vehicle, are discharged to the outside of the vehicle by means of a second blower, and not by a front seat blower, for discharging the air to the rear seats.

A vehicle has a seat movable between an upright position and a reclined position and an automatically adjustable headrest connected to the seat, the automatically adjustable headrest being automatically adjusted for a posture of a head of a user when the user is reclined in the reclined position. The automatically adjustable headrest is automatically adjusted in response to a camera detecting that the user is sleeping or resting either on his or her back or on his or her side, the headrest being adjusted for either a side sleeping posture or a back sleeping posture.

An instrument panel includes an instrument panel body fixed to a vehicle body, and a cover that covers a space of the instrument panel body from a rear in a front-rear direction of a vehicle and faces an occupant in the front-rear direction of the vehicle. The instrument panel body includes a harness holder configured to hold a wire harness arranged in a vehicle width direction. The harness holder extends along the vehicle width direction in the space of the instrument panel body, and includes a fragile portion provided in at least one position in a longitudinal direction of the harness holder. A sectional area of the fragile portion is smaller than a sectional area of the other portion of the harness holder.
