Abstract: Embodiments of the present invention provide techniques for ventilating an enclosure such as the cargo space of a vehicle. In an example implementation, a ventilator is affixed to an external wall (e.g., the roof) of the cargo space. The ventilator includes a ram inlet that flows into a venturi, along one or more openings in a boundary of the cargo space, and exits at an outlet. When the vehicle is in motion, external airflow enters the ram inlet, gets compressed in the venturi, and travels over the top of the boundary, generating a high shear that pulls airflow from the cargo space, into the diffuser, and out the outlet. The ventilator may include an electric fan that generates suction from the cargo space when the vehicle is stationary, and a moveable flap at the inlet that directs the suction towards the cargo space when the vehicle is stationary.

Abstract: A vehicle air-conditioning apparatus includes a filter case configured to accommodate a filter, and a filter cover configured to couple to an open upper end of the filter case. The filter case defines an inner space configured to accommodate the filter therein and having the open upper end to receive and discharge the filter therethrough. The inner space is inclined with respect to a vertical direction to allow the filter to be received into and discharged from the filter case in an inclined state. The filter cover includes a fixing protrusion protruding from a lower surface of the filter cover facing the inner space of the filter case and being configured to press and fix the filter in the inner space.

Abstract: A water separator reduces a water content of an air stream, which is used in an HVAC unit for a vehicle. The water separator includes a diverter wall and an adjacent wall spaced from the diverter wall to define an air passage. The diverter wall has a terminal end extending into the air passage for changing a direction of the air stream to reduce the water content of the air stream. A filter assembly is disposed through a receiving slot in the diverter wall and is within the air passage downstream of the terminal end.

Abstract: A utility vehicle (10) comprising a ventilation system (30) which receives air from the environment, filters the air and supplies the filtered air into a cab (18). The system comprises a fan (54) to drive air through a channel from the environment to the cab, and a main air filter arranged within a roof section (24) of the cab and downstream of a pre-filter. The pre-filter (32;72) rotates about a rotation axis which is substantially parallel to the air flow through the pre-filter so as to reduce the particulate matter which reaches the main filter. The rotation of the pre-filter (32;72) creates a centrifugal force which forces the particulate matter radially outwardly to reduce the build-up of matter on the filter, thus reducing the frequency of servicing. The pre-filter can be integrated into a cab ventilation system or provided in a module which can be added to a vehicle having a conventional ventilation system.

Abstract: A system and method for providing filtered and pressurized air into a vehicle cab, enclosure or other interior enclosed environment is described, in which a filtered positive pressure air unit comprises a sealed box, a HEPA filter, a blower, a magnahelic, power source and ductwork. Dirty air is drawn by the blower through the hose and ductwork to the HEPA filter where a certain percentage of impurities of a certain size or larger are removed. Clean air is discharged at a sufficiently high rate to create a positive pressure inside the interior enclosed environment, keeping clean air in, and dirty air out.
