An air flow device for a vehicle including an instrument panel dashboard, and a blower, the air flow device comprising a first outlet on a front upper surface portion of the instrument panel dashboard from which an air is sent along the front upper surface to a first inlet on the instrument panel dashboard into which the air blown from the first outlet is drawn; and a second outlet on a back upper surface portion of instrument panel dashboard from which an air is sent along the back upper surface to a second inlet on the instrument panel. The blower outlets are installed so as to open parallel to the blower inlets along an upper surface portion of the instrument panel dashboard.

Disclosed herein is an air conditioning system for a vehicle, in which an air conditioning unit having noise inducing unit is arranged at an engine room based on a dash panel and a distribution duct for distributing air to the interior of the vehicle is arranged in the interior of the vehicle based on the dash panel, thereby reducing noise and vibration in the interior of the vehicle, securing visibility and enabling a worker to easily access the air conditioning system for follow-up service because the air conditioning unit causing noise is arranged inside the engine room, and enhancing passengers' convenience by maximizing the interior space of the vehicle in comparison with the conventional air conditioning systems because only the distribution duct is arranged in the interior of the vehicle.

Disclosed is a vehicle air conditioning device, which is an air conditioning device using an integrated heat pump system, and in which left and right independent air conditionings can be implemented in a simple structure such that the left and right air volumes may be automatically controlled, the ability to mix hot and cold air is improved, and sufficient space can be secured inside a vehicle.

A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

A vehicular air conditioning system includes an intake unit configured to inhale an indoor air and an outdoor air. The intake unit includes an outdoor air inlet configured to introduce the outdoor air, an indoor air inlet configured to introduce the indoor air and a plurality of doors configured to selectively open the outdoor air inlet and the indoor air inlet. The intake unit further includes an auxiliary indoor air introduction part configured to introduce the indoor air. The auxiliary indoor air introduction part is configured to introduce a part of the indoor air existing on the side of the indoor air inlet.

A vehicle front arrangement structure includes high-voltage equipment, air conditioning equipment that includes an air-conditioner blower, and a high-voltage connector part. The high-voltage equipment and air conditioning equipment are arranged in front of a vehicle. The high-voltage connector part is provided at a vehicle rearward end portion of the high-voltage equipment to connect a high-voltage wire harness. The high-voltage connector part is arranged so as to be displaced in at least one of a vertical direction and a horizontal direction as viewed from the front of the vehicle.

An air conditioning device for a vehicle includes a first flow path through which air subject to dehumidification flows, a second flow path through which air for recovery flows, a desiccant part and a controller. The desiccant part is fluidly communicated with the first and second flow paths, and configured to adsorb moisture contained in the air subject to dehumidification, and to discharge the moisture to the air for recovery. The controller is configured to control an air volume of the air subject to dehumidification and an air volume of the air for recovery so that the air volume of the air for recovery is less than the air volume of the air subject to dehumidification, after the air volume of the air for recovery reaches a prescribed air volume for achieving a target dehumidification amount of the air subject to dehumidification.

The invention concerns a method for controlling a system (1) for a motor vehicle, said system comprising at least: an actuator, a volatile memory (RAM) in which at least one item of position information of the actuator (IP.sub.RAM) is stored, a long-term memory (EPROM) in which the following are stored: o at least one item of position information (IP.sub.ROM) of the actuator, o an item of information relating to the powering down of the actuator (I.sub.HT), this item of information assuming a first value (v1) when the system has been powered down in a controlled manner and assuming a second value (v2) when the system has suffered a fault causing the current value of the position of the actuator stored in the volatile memory (RAM) to be deleted, in particular when the system has stopped being powered electrically as the result of an error, or communication between the system and a computer has been cut off as the result of an error.

An air conditioning control system and method for a vehicle may include: an alternate control entering temperature difference excess determination step of determining whether a difference in temperature between a side vent temperature sensor and a shower duct temperature sensor exceeds an alternate control entering temperature difference; and an alternate control step of determining that a side vent grill may have been closed, when the difference exceeds the alternate control entering temperature difference, and performing an alternate control operation of regarding the temperature of air measured by the shower duct temperature sensor as the temperature of air discharged from the side vent grill and controlling a temperature of air to be discharged from a center vent grill.

A heater duct can be coupled to an instrument panel of a vehicle, and comprises a base, a nozzle, and a neck. The base is sealingly coupled to the instrument panel and includes an inlet opening to receive air from a heater. The nozzle includes an outlet opening and is fluidly connected to the base. The nozzle deflects the air through the outlet opening and toward a predetermined region of a windshield. The neck extends between and is sealingly coupled to the base and nozzle. The base, nozzle, and neck cooperate to at least partially define an interior volume. The heater duct is positioned in an orthogonal coordinate system comprising an x-axis, a y-axis, and a z-axis. Air flowing from the inlet opening through the interior volume toward the outlet opening follows a path sequentially extending in substantially a negative z-direction, substantially a negative y-direction, and substantially a positive z-direction.
