Some embodiments provide a vehicle climate control system for controlling climate conditions in various cabin regions of a vehicle cabin, where the climate control system is configured to control one or more vehicle components to change the set of climate conditions associated with one or more cabin regions to approximate a set of optimal comfort conditions. The climate control system controls various vehicle components to control climate conditions, including window assemblies, sunroof assemblies, etc. The climate control system determines optimal comfort conditions which optimize perceived temperature of various occupant body parts and maintain various climate characteristics within one or more sets of thresholds. Output configurations of various vehicle components can be determined based at least in part upon determined optimal comfort conditions of various cabin regions. Output configurations can be generated based at least in part upon various control mode priorities.

A climate control system in a vehicle comprises a first vent unit adjacent to a driver seat; a second vent unit adjacent to a passenger seat; a climate control device configured to provide conditioned air to an occupant compartment; and a user input device to enable selection of a first climate control mode or a second climate control mode by a user. The conditioned air passes through the first vent unit at the first climate control mode and the conditioned air passes through the first and second vent units at the second climate control mode.

An air conditioner for a vehicle includes: a casing to accommodate a cooler and a heater; a front temp door disposed in the casing to control a temperature of air supplied to a front seat zone; a rear temp door disposed under the front temp door to control a temperature of air supplied to a rear seat zone; and a rear vent disposed at a lower portion of the casing to discharge air to the rear seat zone. The air conditioner can secure the flow rate of the air that is supplied to the rear seat zone of the interior of a vehicle by improving the route for flow of the air that is supplied to the rear seat zone.

An air conditioner has: an air-conditioning case including an air passage; a plate-shaped door body that rotates about a rotation shaft; and an opposing wall provided in the air passage to define a gap between a tip portion of the door body and the opposing wall. A length of the opposing wall in a circumferential direction of the rotation shaft is larger than a thickness dimension of the tip portion of the door body. The opposing wall includes a first door facing surface and a second door facing surface. The air-conditioning case has a connecting surface connecting the first door facing surface and the second door facing surface. The second door facing surface is located outward with respect to the rotation shaft in a radial direction than the first door facing surface is.

The present invention relates to an air conditioner for a vehicle, which can remarkably improve resistance against an air flow in an air passageway, thereby enhancing efficiency. The air conditioner for a vehicle includes: a case having an air inlet, an air outlet, and an air passageway formed therein; a blower unit for blowing air to the air inlet; and a cooling means and a heating means disposed in the air passageway of the case in an air flow direction in order, wherein the air outlet of the case includes a floor outlet and vent outlets, the floor outlet and the vent outlets are arranged below the heating means in a height direction, and the floor outlet is arranged within a range of the width of the heating means.

Disclosed herein is an air conditioner for a vehicle, which can prevent reduction of an air volume by reducing a back-and-forth width of the vehicle and sufficiently securing the degree of opening of a warm air bypass door, and control an efficient linkage between the warm air bypass door and a defrost door. The air conditioner includes: an air-conditioning case having an air passageway formed therein; a heat exchanger for cooling and a heat exchanger for heating which are disposed in the air passageway of the air-conditioning case to exchange heat with air passing the air passageway; a warm air bypass passageway for directly discharging the air passing the heat exchanger for heating to a front seat floor vent; and a warm air bypass door for adjusting the degree of opening of the warm air bypass passageway, wherein the warm air bypass door includes a rotary shaft and a plate, and the plate has a bent portion to have at least two sides.

A heating, ventilation and/or air conditioning unit (10) for a car is specified, having a first air guide (22) for guiding a first, cold air stream and having a second air guide (24) for guiding a second, warm air stream which is separate from the first air stream, wherein a heating device (26) for warming the second air stream is arranged in the second air guide (24). The heating, ventilation and/or air conditioning unit (10) furthermore has a first mixing chamber (28) and a second mixing chamber (30), wherein the first mixing chamber (28) and the second air guide (24) each have at least one inlet opening (32, 34) to the second mixing chamber (30). In the second air guide (24), there is arranged a flap (44) which is movable between a closed position, in which a flow path of the second air stream to the first mixing chamber (28) is closed, and an open position, in which the second air stream can flow into the first mixing chamber (30), wherein the flap (44) is arranged downstream of the heating device (26) and at an inlet opening (27) of the second air guide (24) into the first mixing chamber (28).

A vehicle-use air conditioning device that supplies air to a side vent aperture portion regardless of a discharge mode, and allows a discharge of air from a defrost aperture portion when a discharge mode that maximizes a ratio of air blown to a passage communicating with a foot aperture portion is employed, is such that a change in an amount of air supplied from the defrost aperture portion is restricted using a simple structure that does not necessitate fine adjustment, even when an air passage on a downstream side of the side vent aperture portion is closed. A passage (a third passage 23) communicating with a side vent aperture portion 17b to a downstream side of heat exchangers 6, 7 is configured of a passage that, when a rotary type first door 25 that adjusts ratios of air blown to a first passage 21 communicating with a foot aperture portion 18 and a second passage 22 communicating with a defrost aperture portion 16 and a center vent aperture portion 17a is in a discharge mode position that maximizes the ratio of air blown to the first passage 21, connects a region to an upstream side of the first door 25 and the side vent aperture portion 17b, regardless of a discharge mode.

A vehicular air-conditioning device includes an inside air temperature detector, an inside air-conditioning portion, and an air-conditioning controller. The inside air-conditioning portion includes a temperature adjuster and a blower. The air-conditioning controller includes an auto control portion, an open signal detector, a thermal load determiner, and a power saving control portion. The auto control portion is configured to perform an auto control. The open signal detector is configured to detect an open signal. The thermal load determiner is configured to determine whether a thermal load on the passenger compartment exceeds an air-conditioning capacity of the auto control. The power saving control portion is configured to perform a power saving control to limit an increase of a power consumption regardless of the inside air temperature when the open signal is detected and it is determined that the thermal load exceeds the air-conditioning capacity of the auto control.
