An air conditioning system for a vehicle may include a cooling duct provided with a cooling duct inlet at a first end of the cooling duct, and a cooling duct indoor outlet and a cooling duct outdoor outlet at a second end of the cooling duct, a heating duct provided with a heating duct inlet at a first end of the heating duct, and a heating duct indoor outlet and a heating duct outdoor outlet at a second end of the heating duct, and including a condenser disposed in the heating duct, an extension duct extending from both the cooling duct indoor outlet and the heating duct indoor outlet, and channeling air supplied from both the cooling duct indoor outlet and the heating duct indoor outlet to a passenger compartment, and a passage control door provided at an indoor outlet end portion of a partition wall.

The invention concerns a control device (1) for a heating and/or ventilation and/or air conditioning installation of a motor vehicle, the installation comprising an air treatment unit (9) comprising air outlets intended to open into a zone (ZG, ZD) of the passenger compartment of the vehicle, including at least first and second air outlets, and at least first (21) and second (23, 25) members for mixing the air flow. According to the invention, the device (1) comprises a user interface (5) comprising at least first (51) and second (53) control members, and a control circuit (7) for receiving, from each control member (51, 53), an input signal with its own temperature setpoint, and for delivering separate control signals for controlling the first and second mixing members (21, 23, 25).

A vehicle control device is used for a vehicle that transports a user and a package. The vehicle control device includes a controller configured to: acquire an attribute of the user and an attribute of the package; partition a space in the vehicle into spaces prior to loading of at least one of the user and the package into the vehicle; and perform air conditioning control according to the attribute of an object for loading in at least one of the partitioned spaces.

Disclosed herein is an air conditioning system for a vehicle which includes an air-conditioning module having an air-conditioning case, which has a cold air passageway and a warm air passageway partitioned from each other, and a blower unit, and an indoor air inflow duct for introducing indoor air of the interior of the vehicle into the blower unit, wherein an outlet of the air-conditioning case and an inlet of the indoor air inflow port are arranged to be adjacent to each other, so that the air conditioning system for a vehicle can be installed through just one through hole part formed in a dash panel, thereby enhancing assemblability and reducing weight and an installation cost.

An air conditioning system for a vehicle is provided. The system includes a cooling duct and a heating duct provided as spaces partitioned by a partition wall and an evaporator core and an inner condenser disposed respectively in the cooling and heating ducts. An outer condenser is connected to the inner condenser and the evaporator core via one refrigerant passage. An air volume regulation door is disposed upstream of the evaporator core and the inner condenser in an air flow direction, and a common blower is disposed at one side of the cooling and heating ducts to simultaneously form an air flow in the cooling and heating ducts.

An air conditioning system for a vehicle is provided. The air conditioning system includes a cooling module having a cooling duct and an evaporator core, and a heating module having a heating duct and an inner condenser. Additionally, an outer condenser is disposed extraneous to the heating duct, and a blower forms air flow in the cooling duct or the heating duct. The inner condenser, the outer condenser and the evaporator core are connected via a single refrigerant passage.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle includes an evaporator and a diffuser. The evaporator is configured to cool air passing through the evaporator. The diffuser is configured to direct a first portion of the air entering the diffuser through a first section of the evaporator, and direct a second portion of the air entering the diffuser through a second section of the evaporator. The evaporator and the diffuser are configured to cooperate such that air exits the first section at a first temperature and air exits the second section at a second temperature less than the first temperature.

An vehicle air conditioner (1A) includes a duct (3) in which a partition member (4) forming a first flow path (3A) and a second flow path (3B) is provided, and a heat pump circuit (2A). In the heat pump circuit (2A), a first indoor heat exchanger (12A) that contributes mainly to heating is located in the first flow path (3A) or faces an outlet of the first flow path (3A), and a second indoor heat exchanger (12B) that contributes mainly to cooling is located in the second flow path (3B). The ratio between an internal air and an external air within air flowing through each of the first flow path (3A) and the second flow path (3B) is adjustable. The duct (3) is provided with at least one of a heating exhaust port (35) for discharging air cooled in the second indoor heat exchanger (12B) to the outside of the vehicle interior in heating operation, and a cooling exhaust port (36) for discharging air heated in the first indoor heat exchanger (12A) to the outside of the vehicle interior in cooling operation. This configuration enables the air within the vehicle interior, the temperature of which has been adjusted by heating or cooling, to be efficiently utilized without wasting energy by discharging the air as it is to the outside.

A heating device may include: a heater; an upper surface-side member facing an upper surface of the heater; and a lower surface-side member facing a lower surface of the heater; and an upper surface-side passage defined between the heater upper surface and the upper surface-side member; and a lower surface-side passage defined between the heater lower surface and the lower surface-side member; and a first spacer disposed between the heater upper surface and the upper surface-side member to secure a space between the heater upper surface and the upper surface-side member; and the upper surface-side member; and a second spacer disposed between the heater lower surface and the lower surface-side member to secure a space between the heater lower surface and the lower surface-side member; and an elastic member pressing the upper surface-side member or the lower surface-side member toward the heater.

A vehicle air conditioner includes a first passage and a second passage and is capable of operating in such a manner that outside air introduced in the first passage is conditioned by an evaporator and a heater core and subsequently blown, as a conditioned air, from a defrost outlet, side defrost outlet and side vent outlet toward windowpanes and, at the same time, inside air introduced in the second passage is conditioned by the evaporator and the heater core and subsequently blown, as a conditioned air, from a center vent outlet and front and rear heat outlets into a passenger compartment.
