An air circulator for a vehicle is provided. The air circulator includes a blower case and a connection duct that is connected to an outlet of the blower case. The connector duct includes a first path and a second path that are divided by a separation plate. Additionally, a filter is mounted in the outlet of the blower case and an inlet door is mounted in the blower case to selectively allow air to be blown into the first path and/or the second path.

A car roof automatic HVAC apparatus disposed within a roof of an automobile to maintain a more comfortable temperature inside of the automobile for a driver to return to, and to act as a safety mechanism to prevent a child or pet left inside the automobile from dying of excessive heat or cold. A plurality of vents has a plurality of fans disposed within, and a heater allows the fans to blow hot air when needed. A first CPU, the heater, a light, the plurality of vents, and the plurality of fans are powered by a rechargeable battery or an alternate power source. A remote control can be used to operate the car roof automatic HVAC apparatus. An automobile interface unit disposed within the automobile can detect when the vehicle has been turned off for a programmed amount of time to automatically begin ventilation or heating.

A car air-conditioning duct guides air to a suction side of an air conditioner mounted on a car or guides the air flowing from a blow-off side of the air conditioner. The car air-conditioning duct includes a duct wall having a tubular shape and forming a duct outer surface and a duct inner surface. The duct wall is made of a composite foamed resin material containing polystyrene resin and polyolefin resin.

A riding vehicle is provided with a downdraft fan assembly mounted on a vehicle roll bar for providing a flow of ambient air over the vehicle operator and a canopy carried by the fan assembly and providing solar and precipitation protection for the operator.

A vehicle is provided herein. The vehicle includes a windshield positioned between an instrument panel and a headliner. A duct is positioned above the headliner and has an inlet and an outlet. An air conditioning system is configured to push conditioned air out of the instrument panel generally toward the inlet. A fan is proximate the inlet and is configured to draw the conditioned air into the inlet and push the conditioned air out of the outlet toward a vehicle window proximate the outlet.

A filter arrangement for a vehicle includes a flat filter element. The filter element has a filter medium and is integrated into an interior component of the vehicle. The filter element forms a surface facing an interior of the vehicle. In an embodiment, air flows through the filter element, and the air exits through the filter element into the interior of the vehicle.

An air filtration system for a mobile unit having a vent fan and a kit for forming the air filtration system. The air filtration system includes a rigid outer cover made, a filter box, and a vent fan installed on a roof of the mobile unit. An air inlet passageway is formed in the rigid outer cover so that the vent fan may draw outside air through the filter box and into an interior space of the mobile unit. The air inlet passageway may include a louver for allowing air entry while protecting the filter box from rainwater. A base plate has a central opening that is positionable around a vent fan housing and securable to a vent fan flange to form a flat surface upon which to receive the filter box and the rigid outer cover.

A vehicle vent top cover still capable of ventilation in a closed state of the top cover, which includes a top cover body, which includes a top plate; a fixed rim and side protection plates are arranged below the top plate; the fixed rim is located at the inner side of the side protection plate; the fixed rim is provided with a first ventilation groove; an air duct structural frame is fixed below the top plate; the air duct structural frame is located above the bottom walls of the side protection plates; the first ventilation groove and an upper surface of the air duct structural frame form an air inlet; one side of the air duct structural frame close to the side protection plate is provided with a second ventilation groove; and the second ventilation groove and the side wall of the side protection plate form an air outlet.

In a vehicle, a flow adjusting plate is placed along an upper edge part of a front windshield, so that the flow of wind flowing along an inner surface of the front windshield is adjustable by the flow adjusting plate. Further, the angle of the flow adjusting plate from the inner surface is adjustable, so that the flow adjusting plate allows the direction of the wind flowing along the inner surface to be directed toward a seat placed behind an instrument panel in the vehicle front-rear direction.

A recreational vehicle and an air conditioner therefor are provided. The air conditioner includes an indoor cover defining an indoor portion and an outdoor portion with an outdoor heat exchanger and an outdoor fan disposed in the outdoor portion and an indoor heat exchanger and an indoor fan disposed in the indoor portion. The air conditioner also includes an indoor panel defining an air inlet and an air outlet. An acoustic insert includes a solid top wall and at least one permeable side wall. The acoustic insert is positioned between the indoor panel and the indoor fan, whereby the acoustic insert dampens sound transmitted through the indoor panel.
