A vehicular air conditioning system and a control method thereof are provided. The vehicular air conditioning system includes: a plurality of mode doors configured to switch an air discharge mode in a passenger compartment, the mode doors including a defogging door, a vent door and a floor door; and a mode door air pressure reduction part configured to temporarily reduce an air pressure acting on at least one of the mode doors when the air discharge mode is switched.

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.

A cab for an agricultural working vehicle has a cab base and a cab roof, between which a windshield and side windows are situated in a frame structure, and a driver's seat situated on the cab base. There is at least one air treatment device for cooling and heating an inlet air flow which is supplied to the cab through an intake duct. The air treatment device has at least one first air distribution duct having at least one first air outlet opening, and at least one second air distribution duct having at least one second air outlet opening. The first air outlet opening outputs a first air flow substantially along the windshield and the second air outlet opening outputs a second air flow directed in the direction of the driver's seat. The first air flow has a higher temperature than the second air flow.

A vehicle air conditioning setting device functioning with a vehicle air conditioning device for setting a direction of air blown out from an air outlet and a degree of concentration and diffusion of the air is provided. The vehicle air conditioning setting device includes: a display unit that displays an air range designation image including an occupant image representing an occupant seated on a seat of the vehicle; a touch panel overlapped with the display unit; and an air range setting unit that sets an air range representing the direction of the air and the degree of concentration and diffusion of the air based on an operation range of the touch panel on the air range designation image. When a drag operation is performed on the touch panel, the air range setting unit sets the air range based on a range of the drag operation.

An air-conditioning apparatus for an electric vehicle and a method of controlling the same, may include a heat exchanger performing heat exchange between a first fluid and a second fluid while the first fluid and the second fluid flow separately from each other therethrough; a heat source connected to the heat exchanger through a line through which the second fluid flows to allow the second fluid to circulate between the heat exchanger and the heat source, and heating or cooling the second fluid; a circulator imparting a circulation force to the second fluid such that the second fluid circulates between the heat exchanger and the heat source; and a controller determining a required flow rate of the second fluid by use of a flow rate of the first fluid flowing through the heat exchanger and controlling the circulator on the basis of the required flow rate of the second fluid.

An object of the present invention is to provide a vehicular air conditioning apparatus capable of varying the temperature of air that has passed through a heater core in the up-down direction of the heater core while achieving downsizing. The vehicular air conditioning apparatus includes an electric heater (43) that is provided in a flow channel defined by a housing on the downstream side of an evaporator, that includes heater circuits (48, 49), and that configures a heater core (17) that heats air cooled by the evaporator, and a control device (25) that separately controls the heater circuits (48, 49). The heater circuits (48, 49) are arranged in the up-down direction of the heater core (17).

An HVAC module having a reconfigurable bi-level duct system is disclosed. The air duct includes an air duct inlet in fluid communication with the HVAC module, an interior wall dividing the air duct into first and second air passageways, a bypass port enabling fluid communication between the first air and second air passageways. A downstream control valve disposed adjacent the bypass port and is configured to selectively direct air flow from one of the first and second air passageways to the other of the first and second air passageways. An upstream flow control valve is disposed adjacent to the inlet of the air duct, wherein the upstream flow control valve is configured to selectively direct air flow from the hot and cold chambers of the HVAC module to the first and second air passageways of the air duct.

The present invention relates to a system for cooling a vehicle electric component including: a compressor compressing a refrigerant; a condenser connected to the compressor to condense the refrigerant supplied from the compressor and formed to surround an outer periphery of the compressor; an expansion means connected to the condenser to expand the refrigerant supplied from the condenser; an evaporator connected to the expansion means and the compressor to evaporate the refrigerant supplied from the expansion means by a heat exchange and then introduce the evaporated refrigerant into the compressor; and a blower fan disposed on one side or the other side of the condenser which is opened, wherein the system for cooling a vehicle electric component may effectively cool electric components such as a variety of sensors and computers of an autonomous vehicle and may secure a sufficient cooling performance by using a vapor compression system.

A housing assembly for an HVAC system includes a first shell having a first boss having a first bore configured to receive a fastener therein. The housing assembly further includes a second shell having a second boss having a second bore. The housing assembly further includes a divider disposed between the first shell and the second shell, the divider having a divider bore configured to receive the first boss therein and a divider counterbore configured to receive the second boss therein. A diameter of the divider bore is less than a diameter of the divider counterbore. The divider bore and the divider counterbore are coaxial and configured to receive the fastener extending therethrough.

An air conditioning system includes an air conditioning unit that includes an introduction part that introduces air, a plurality of temperature adjustment parts that cool or heat introduced air, and a discharge part that discharges cooled or heated air to an inside of the vehicle. The air conditioning system further includes an outdoor duct connected to a discharge-part side of the air conditioning unit and extending toward an outdoor side of the vehicle to discharge the cooled or heated air to an outside of the vehicle. Additionally, the air conditioning system includes an outdoor door provided on the outdoor duct or on the discharge part of the air conditioning unit around the outdoor duct to control air flow through the outdoor duct.
