A motor-vehicle includes one or more electrically-operated valves, arranged on the structure of the motor-vehicle in a lower position with respect to the windows, for providing a communication between a passenger compartment and the external environment, and one or more electronic control units programmed to activate a ventilation mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle. The ventilation mode includes controlling at least partial opening of one or more windows and the opening of one or more of the valves to generate a flow of natural air from the bottom upwards through the passenger compartment of the motor-vehicle.

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. 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.

A ventilating tube may include a body through which air is flowable in an air flow direction and a sound attenuating mechanism for attenuating airborne noise. The sound attenuating mechanism may be a wavelength resonator, which may include at least one resonance chamber. On one side, the at least one resonance chamber may have an opening which opens the at least one resonance chamber into the body transversely to the air flow direction.

A vehicle including a cab having a frame with at least two support posts each including an airflow path therein and an airflow system supported by the cab and configured for increasing an airflow into the cab and decreasing a power consumption of the cab. The airflow system includes at least one air intake opening in the cab configured for intaking a fresh air, an air filter fluidly coupled to the at least one air intake opening, and an air outlet within the cab and fluidly coupled with the air filter. The fresh air flows into the at least one air intake opening, through each respective airflow path of the at least two support posts, is filtered by the air filter, and flows out through the air outlet into the cab.

A connecting pipe is made from polymer material and is shaped to link an opening of an air inlet pipe of a thermal device of a motor vehicle and an opening of a firewall of the vehicle. The connecting pipe has a cross section equal to or greater than a cross section of the air inlet pipe. The connecting pipe has two open ends. The two open ends include a first open end having a first interface which is shaped to be assembled and fixed to the air inlet pipe, and a second open end having a second interface which includes a bearing surface which is shaped to be applied against the firewall on the periphery of the firewall opening.

The present disclosure provides a casing for an air conditioning unit including a main body, a door, a passing defining member, and a drain channel. The main body includes a fresh-air passage and a recirculation-air passage. The recirculation-air passage is positioned below the fresh-air passage. The door selectively opens and closes a communication hole through which the fresh-air passage and the recirculation-air passage are in fluid communication with each other. The passage defining member is disposed upstream of the communication hole and defines a lower side of the fresh-air passage. The drain channel extends from the passage defining member to a space outside of the recirculation-air passage to discharge condensed water generated in the fresh-air passage.

A first case member of a blower unit has a first communication passage communicating with an air intake side of a blower. A second case member of a temperature adjustment unit has a second communication passage communicating with a condensed water discharge portion through which condensed water is discharged. The respective case members are joined with each other in a state where a portion forming the first communication passage and a portion forming the second communication passage face each other. The portion of the first communication passage includes a drain portion having a groove shape and configured to discharge water in the first communicating passage. The portion of the second communication passage includes a drain receiving portion having a groove shape, communicating with the first communication passage and receiving the water discharged from the drain portion.

The present invention relates to an electrification apparatus for electric dust collection and an air conditioner for a vehicle comprising the same. According to the teachings of the present invention, there is provided an electrification apparatus for electric dust collection including: a frame, conductive microfiber and conductive. The frame includes a main body frame in which the conductive plate is installed and an installation frame in which a fixing groove in which the conductive microfiber is installed is formed. At this time, the electrification apparatus for electric dust collection further includes a rubber which is coupled with the conductive microfiber and is inserted into the fixing groove.

Cabin air treatment apparatus for an agricultural machine, comprising at least an external air inlet (11, 16), a filtration system (20), an HVAC system (30), and a cabin air supply outlet (40). The apparatus further comprises a hermetically closed box (1) inside which the HVAC system (30) is housed, the box having a levelling opening (60) for placing the box (1) into communication with a cabin (C) of the agricultural machine to level a pressure inside the box (1) with a pressure inside the cabin (C), wherein said at least one external air inlet comprises a first external air inlet (11) formed on the box (1). The filtration system comprises a first filter (21) for effecting a filtration of at least one among dust, aerosols and vapours, arranged at the first air inlet (11), and a blower (22) for drawing air from the first air inlet (11) and delivering it to the HVAC system (30), said blower being arranged directly connected downstream of the first filter (21) and inside the box (1).

A blower case for a heating, ventilation, and air conditioning (HVAC) system. The blower case includes an inlet for airflow entering the blower case. Also included is a dehumidifier, which is movable between a first position and a second position. In the first position the dehumidifier is in a path of airflow entering the blower case through the inlet. In the second position the dehumidifier is not in the path of airflow entering the blower case through the inlet.
