A discharged air flow path connected to a cooling fan has a first discharged air flow path which is connected to at least one side trim of a left side trim and a right side trim and a second discharged air flow path which branches off from the first discharged air flow path and which is connected to the side trim. A first connecting portion which connects the first discharged air flow path and the side trim is disposed so as to be spaced away from a second connecting portion which connects the second discharged air flow path and the side trim in a front-rear direction. The first discharged air flow path and the second discharged air flow path discharge air into a passenger compartment by way of the side trim.

Air conditioner for vehicle, small and having two independent air flow paths, controlling air volume independently for each air flow path, and can remove noise while regulating the air volume corresponding to the desired flow path through means for returning flowing air toward a suction port. The air conditioner for vehicle comprises a blower having a plurality of blower wheels, and one blower motor for driving the plurality of blower wheels with the same force, a plurality of inlet flow paths allowing an air inflow port to communicate with a blower inlet, and a return flow path which has a plurality of outlet flow paths allowing a blower outlet to communicate with an air discharge port, which returns, to the blower inlet, at least a part of the air discharged from the blower outlet so that the air volumes discharged from the plurality of air discharge ports are regulated differently.

A vehicle air-conditioning system has an intake door that switches between an inside air recirculation mode to take in air from an inside air introduction port and an outside air introduction mode to take in air from an outside air introduction port, a blower that blows the air introduced through any of the inside air introduction port and the outside air introduction port toward inside of a vehicle cabin, a heater that heats the air blown by the blower, and a controller that activates the heater when there is a request for heating the inside of the vehicle cabin, controls air conditioning such that an environment inside the vehicle cabin becomes a desired environment by set estimated time of departure.

A passenger compartment module block assembly is provided. The passenger compartment module block assembly includes a center block which is made of composite material and disposed within a central portion of a crash pad and provided with assembly components formed on opposite sides of the center block, a driver block which is made of composite material and coupled to a first-side assembly component of the center block and disposed adjacent to a driver seat. A passenger block which is made of composite material and is coupled to a second-side assembly component of the center block and disposed adjacent to a passenger seat. The center block, the driver block and the passenger block are assembled integrally with each other and are disposed between a dash panel and a crush pad of a vehicle and to improve torsion and bending stiffness of the vehicle.

A HVAC apparatus for a vehicle having a fan unit with at least one impeller driven by a motor; a heat exchanger unit forming an air duct receiving air from the fan unit, wherein the heat exchanger unit comprises a heat exchanger having at least two different cooling regions with different working temperatures through which received air flows consecutively; and wherein the different working temperatures are controlled by a temperature control unit; and a plate-shaped housing accommodating the fan unit and the heat exchanger unit.

A vehicle heat exchange system includes a cooling heat exchanger provided in a cooling water circuit, a first air-conditioning heat exchanger as an evaporator in a heat pump system, a hydrothermal-medium heat exchanger as a refrigerant condenser in the heat pump system, a second air-conditioning heat exchanger, and an air conditioning passage in which the first air-conditioning heat exchanger and the second air-conditioning heat exchanger are disposed. A vehicle interior-exterior communication port is provided at a downstream side of the second air-conditioning heat exchanger in the air conditioning passage, to guide the air having passed through the second air-conditioning heat exchanger, to an outside of the vehicle interior. The cooling water for cooling the heating element flows through the second air-conditioning heat exchanger, and the air having passed through the second air-conditioning heat exchanger is discharged outside the vehicle interior through the vehicle interior-exterior communication port.

An armrest according to one embodiment of the present invention includes a case including a passage which guides a flow of air while the air is introduced and discharged and a through-hole which is formed via the passage to allow the air to be discharged outward, a fan located inside the case and by which the air is introduced and discharged through the passage, a heating element configured to supply heat to the air discharged by the fan and an outer surface of the case, and a supporter configured to support an external force applied to the case in at least two directions to keep a shape of the case.

According to some embodiments, there is provided an air conditioning system for a vehicle. The vehicle may be a locomotive. The air conditioning system includes a combination module for mounting in or on a vehicle. The combination module includes a condenser coil and a compressor assembly. The compressor assembly includes an electric motor. The combination module may be mounted to cover a hole in an outer wall or floor of the vehicle, such that air enters the hole ventilates the condenser coil. The system also includes at least one air handler for mounting in a cab of the vehicle, remote from combination module. Each air handler comprises a respective evaporator coil. A combination module including a compressor assembly is also provided. A method for installing the combination module is also provided.

An air conditioner energy-saving inflatable device is adapted to be disposed in a vehicle body. The air conditioner energy-saving inflatable device includes an air pump, an air bag, a circuit board and a sensor. The air bag is connected to the air pump and adapted to be disposed beside an area in the vehicle body. The circuit board is electrically connected to the air pump and includes a controller. When an air-conditioning system of the vehicle body is activated, the sensor is adapted to sense whether the area is vacant. When the sensor senses that the area is vacant, the controller instructs the air pump to inflate the air bag, so that the air bag fills at least a portion of the area. When the air-conditioning system of the vehicle body stops running, the air bag is deflated. A vehicle is also provided.
