A natural ventilator is herein disclosed that is free of moving parts, wind-activated, rain-proof, and free of dust or smog infiltration. It is not only suitable to be a standalone natural ventilator, but is also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system, for such enclosed spaces or objects as buildings and vehicles needing air relief. The ventilator assembly has rainwater-proof shapes or fixtures that serve to defend the vent system, and the interior space being vented, against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds. It also includes shapes or fixtures to prevent fume condensation from drifting outward and staining the exterior of a building or vehicle, or the like, that is being vented.

A system for ventilating a vehicle interior compartment operates, at least intermittently, to set an air quality mode in which fresh air and/or circulated air is supplied to the vehicle interior compartment, and to control an interior compartment pressure in the vehicle interior compartment through variation of the flow resistance of an interior compartment ventilation device in an open-loop and/or a closed-loop manner such that the interior compartment pressure is higher than an ambient pressure outside the vehicle interior compartment.

An air flow control system includes a forming portion, an outside air introduction door, and an air controller. The forming portion forms a front side communication port that communicates between the interior of the vehicle cabin and an engine compartment disposed on the front side in a vehicle traveling direction with respect to the interior of the vehicle cabin and accommodating a traveling engine. The outside air introduction door opens or closes an outside air introduction port to introduce an air flow from an outside of a vehicle cabin into the interior of the vehicle cabin. The air controller controls the outside air introduction door to open the outside air introduction port, and causes the air flow, introduced from the outside of the vehicle cabin into the interior of the vehicle cabin via the outside air introduction port with travel of the vehicle, to be blown from the interior of the vehicle cabin into the engine compartment through the front side communication port.

A device for removing particulates includes an outflow opening and a fan that delivers air through the outflow opening. An air curtain is formed in front of a mouth and nose region of a person by the air delivered by the fan and which is directed in a targeted manner to remove particulates. The device has a collection element with at least one capture opening opposite the outflow opening. A least part of the air curtain, which runs in a plane stretched through transverse and vertical directions of a motor vehicle, is captured by the capture opening to remove at least a part of the particulate.

In a mobility including a negative pressure space and method for controlling a pressure of the mobility in which the mobility is used a general vehicle in normal times, and when a special situation such as transferring infectious disease patients occurs, an internal space includes a general space and a negative pressure space by a partition wall, so that the infectious disease patients are safely transferred through the negative pressure space and the spread of infectious diseases is prevented. As a result, the usability of a vehicle is increased, and it is possible to respond to such special situation.

The present disclosure relates to a mounting assembly for attaching a ventilation device to a structure. The structure comprises an inner surface, an outer surface, and a first opening extending therebetween. The mounting assembly comprises an outer protective member configured to have a top side and a bottom side, a plurality of sealing members, at least one gasket, a bottom mounting member, and a plurality of bolts. The mounting assembly of the present disclosure enables a watertight seal and weatherproof installation of the ventilation device to the structure and prevents theft of the ventilation device. Moreover, the mounting assembly enables easy installation of the ventilation device using one or more components of the mounting assembly, consumes less time, enables easy removal, and is reusable with other ventilation devices. The mounting assembly is cost effective.

The present invention relates to an air conditioner for a vehicle, which includes a cold air passageway and a warm air passageway, and two blowers disposed in the air passageways, thereby rapidly ventilating the interior of the vehicle using the two blowers.

A vehicle air conditioning apparatus is provided. The vehicle air conditioning apparatus includes: a plurality of seat air conditioning units configured to selectively perform cooling or heating for corresponding seats installed in a cabin, respectively; and a plurality of exhaust ducts for discharging, outside the cabin, part of air used in the plurality of seat air conditioning units. At least part of the plurality of exhaust ducts is merged.

A ventilation system is adapted to be used in a vehicle. The vehicle includes a vehicle body that defines an interior space. The ventilation system includes a vent pipe and a fan. The vent pipe is adapted to be disposed on the vehicle body, and has an outside communicating end via which the vent pipe is adapted to communicate with the outside of the vehicle body, and an inside communicating end via which the vent pipe is adapted to communicate with the interior space. The fan is disposed in the vent pipe, and is configured to be activated to produce airflow from the outside communicating end to the inside communicating end.

A vehicle air conditioning apparatus is provided which includes: a plurality of seat air conditioning units configured to selectively perform cooling or heating per corresponding seat among a plurality of seats installed in a cabin, respectively; and a plurality of exhaust ducts for discharging, outside the cabin, part of air used in the plurality of seat air conditioning units. An exhaust duct of a given one of the plurality of seat air conditioning units is connected to an air inlet of another seat air conditioning unit.
