Methods and systems are provided for a vehicle air duct. In one example, a system for a vehicle, includes a passage comprising an inlet at a downstream portion of a front wheel well of the vehicle and an outlet upstream of a rear wheel well of the vehicle.

There is disclosed an environmental control system for thermally conditioning air within an enclosed space comprising: a refrigerant circuit having a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger. The system further comprises an intake flowpath for directing an intake flow of fresh air to the enclosed space, wherein a heat-transfer section of the indoor heat exchanger is located within the intake flowpath to thermally condition the intake flow of fresh air before entering the enclosed space. The system further comprises an exhaust flowpath for directing an exhaust flow of thermally conditioned air to an external environment. A recovery heat exchanger is provided to transfer thermal energy between the exhaust flow and the intake flow at a location within the intake flowpath that is upstream of the heat-transfer section of the indoor heat exchanger.

An air conditioning system of a motor vehicle, having a housing with at least two independent air ducts formed therein, which are arranged separately from each other by at least one partition wall in the housing. A cooling heat exchanger is arranged in the housing such that it is flowed through by air, which can flow into the at least two independent air ducts. A heating heat exchanger is arranged in the housing such that it protrudes into the at least two independent air ducts and is flowed through by air of the at least two independent air ducts. The heating heat exchanger being an electrically operable heat exchanger, which is formed with several independently heated heat exchanger areas, so that the air flowing through an heat exchanger area is independently heatable and each independent air duct is provided at least one heat exchanger area.

An electric vehicle with a cleaning device includes an electric motor, a cleaning device connected with a pipe installed in a vehicle cabin, a first clutch that connects and disconnects the electric motor with an axle of wheels of the vehicle, a second clutch that connects and disconnects the electric motor with the cleaning device, a control unit that controls one of the first clutch and the second clutch to selectively connect one of the cleaning device and the axle with the electric motor and activate the cleaning device.

A vehicle air conditioner, and more specifically, to a vehicle air conditioner in which an air conditioning module and a cooling module are integrally formed, thereby enabling miniaturization so as to enable increased space utilization inside an engine room, and enabling increased manufacturability.

A thermal management module for a vehicle includes: a housing disposed on a cross member between side frames arranged on both sides of an underbody of the vehicle on which wheels and a drive unit are positioned; a cooling/heating heat exchanger; an outdoor heat exchanger; a refrigerant storage; and a refrigerant circulation part. The housing includes a cooling/heating duct connected to an upper body of the vehicle, and a heat exchanging duct connected to the outside of the vehicle. The cooling/heating heat exchanger and the outdoor heat exchanger are disposed on the cooling/heating duct and the heat exchanging duct of the housing. The refrigerant storage and the refrigerant circulation part are provided on sides of the cooling/heating duct and the heat exchanging duct of the housing.

An economical air conditioner system for universal installation in utility vehicles (UTV) and other 12v applications is a fluid cooling system that may also be used for heating applications. The system is a sealed system wherein cooling fluids can include ice water, and the sealed system allows for improved ice retention. The sealed system may alternatively utilize a traditional coolant in the cooling system which provides for the ability to switch between “heat” and “cool” applications or functions using the same core in the system. The system includes a storage vessel, a pump, a fluid reservoir, and a heat exchanger installed within the storage vessel. The system is also operably connectable to a core for temperature selected and directed air flow.

An intake system of an engine mounted on a vehicle where a cabin is air-conditioned by an air conditioner, is provided. A heat exchanger of an evaporator of the air conditioner is divided into a first heat exchanger and a second heat exchanger that are mutually independent, and an air passage includes a first division passage and a second division passage. The intake system cools intake air utilizing a part of the air conditioner, and includes a connecting passage that guides first air cooled by passing through the first heat exchanger, a passage switch, and a controller. When the controller determines that a cooling demand for the intake air exists, it controls the first air to flow into an intake passage through the connecting passage, and when the controller determines that there is no cooling demand, it controls the first air to flow into the first division passage.

An air conditioner for a vehicle may include a first air conditioner provided on the engine compartment side with respect to a dash panel, and including an intake unit of suctioning internal or external air and blowing same to the vehicle interior side; and a second air conditioner provided on the vehicle interior side with respect to the dash panel, and including a duct for discharging conditioned air to the vehicle interior side. The dash panel has a through hole formed therein, and has an air guide which connects the first air conditioner and the second air conditioner to each other through the through hole.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.
