In order to provide a motor vehicle, the roof of which is composed of a transparent material at least in some sections, wherein persons located in the motor vehicle are cooled by means of escaping air, air outlet openings are formed on both sides on opposite roof frame longitudinal segments, in each case in accordance with the number of seat rows. Air lines are provided, which convey air conditioned by at least one present air conditioning system to at least one air outlet opening. Sensors that detect occupancy of the present seats by a person are provided, and a controller for the present air conditioning system is provided, which adjusts an air conditioning system from the number of present air conditioning systems in such a way that an air flow having a predetermined temperature and having a predetermined air outlet speed is applied to an upper region of a person located on a seat.

A vehicle air-conditioning apparatus that exhibits improved energy saving performance is provided. In addition, a vehicle with such a vehicle air-conditioning apparatus is provided. The vehicle air-conditioning apparatus includes a cooler provided in a first air passage, and a first air-sending device including a motor and a fan provided in the first air passage, and configured to drive the fan with the motor to thereby generate an airflow that flows into a vehicle interior through the first air passage. At least a part of an outer surface of the motor is located outside the first air passage.

An environmental control system includes a refrigerant circuit with a pump segment and an evaporator segment, an evaporator arranged along the evaporator segment and in fluid communication with of the refrigerant circuit, and a coolant circuit. The coolant circuit extends through the evaporator and is thermally coupled to refrigerant circuit by the evaporator, the coolant circuit including a first segment and a second segment arranged in parallel with one another to transfer heat from a first zone to a first portion of liquid coolant traversing the coolant circuit and transfer additional heat from a second zone to a second portion of coolant traversing the coolant circuit. Aircraft and environmental control systems are also described.

This vehicle cooling device includes a duct communicating with a heating element disposed in a vehicle, an opening provided in the duct, positioned below a seat surface part of a seat disposed above a floor panel, and opening to a passenger compartment, and a fan supplying air suctioned into the duct from the opening to the heating element, in which the opening is positioned on a vehicle-body rear side with respect to a seat fixing part on a vehicle-body front side among seat fixing parts for fixing the seat to the floor panel in a state in which it is disposed on a vehicle-body rear side of a front end of the seat surface part.

An open architecture HVAC module is disclosed having a housing defining an air inlet and at least two adjacent air outlets. An evaporator and a heater unit are disposed within the housing. A cold air chamber is defined between the evaporator and heater unit, and a hot air chamber is defined downstream of the heater unit. A partition extends into the cold and hot air chambers from an interior surface of the housing between the two adjacent air outlets. The partition is spaced from the evaporator and heater unit. The partition cooperates with the housing to define a first mixing chamber in fluid communication with the first outlet and a second mixing chamber in fluid communication with the second outlet. A blend valve is disposed in each mixing chambers. The blend valves are configured to selectively direct air flow from the cold and hot air chambers to the air outlets.

A rear passenger seat air ventilation system for an electric vehicle includes a rigid tunnel positioned within a passenger compartment of the electric vehicle. The rigid tunnel covers a portion of a battery assembly that extends above a floor structure of the electric vehicle such that the passenger compartment is sealed from the battery assembly. The rigid tunnel defines a forward opening and a rear opening connected by a conduit extending along at least a portion of a length of the rigid tunnel. The conduit is disposed within an interior of the rigid tunnel. A center console is positioned above at least a portion of the rigid tunnel. An air supply system interfaces with the forward opening and to deliver air to the conduit. At least one air vent receives air from the conduit and deliver the air to a rear seating area of the passenger compartment.

A device for distribution of conditioning air for vehicle turret comprises at least one air duct sheath, the sheath comprising a chute adapted to be made integral with the vehicle and a shutter adapted to be made integral with the turret. The sheath is the form of an arch of circle coaxial with the rotation axis of turret. The device comprises at least one duct in the form of an arch of circle having the same average radius as that of the sheath and able to slide with respect to the sheath between a closed position in which the duct connects one end of the sheath to another end of said sheath, or to another sheath, for continuity of airflow between the sheaths, and an open position in which the duct is slid within the sheath so as to leave a passage transverse to the sheath along a circular sector.

An air-conditioning unit is configured to operate in an internal/external air two-layer mode. The air-conditioning unit includes an air-conditioning case defining a passage, a first heat exchanger, a second heat exchanger, an upstream partition and an intermediate partition. The upstream partition and the intermediate partition collectively partition the passage into a first passage through which internal air introduced from an internal air introducing port flows during the two-layer mode and a second passage through which external air introduced from an external air introducing port flows during the two-layer mode. The upstream partition is located upstream of the first heat exchanger and the intermediate partition is located between the first heat exchanger and the second heat exchanger. The intermediate partition is integrally formed with at least one of the first heat exchanger or the second heat exchanger.
