Abstract: A vehicle cabin airflow forming device includes an airflow forming unit. The airflow forming unit is configured to form airflows circulating around seating space of a seat and form, as part of the airflows, an ascending airflow on one lateral side of the seating space, and a descending airflow on the other lateral side of the seating space. The seat is provided inside a vehicle cabin, and the airflows circulate around the seating space as viewed from a front side of the seat.
Abstract: The present invention relates to refrigerated trucks, more particularly to a front-mounted external cold air intake system for a large refrigerated truck, including a refrigerated compartment, an indoor chiller unit, an outdoor chiller unit, a front-mounted air duct, air outlets, horizontal louvers, folding elbows, windshields, blade control knobs, filters, covers, wind deflectors and blades. In the front-mounted cold air intake system, the front-mounted air duct introduces outdoor cold air into the refrigerated compartment, and transmits and distributes the cold air through the air outlets. Moreover, the air window structures formed by the horizontal shutters, the folding elbows and the windshields are used for discharging air, so as to stabilize the pressure in the refrigerated compartment. The system of the present invention uses outdoor cold air to effectively cool the compartment allowing for energy saving of the refrigerated truck.
Abstract: Provided is a railway vehicle air-conditioning duct that is capable of achieving a more uniform in-cabin temperature distribution through more appropriate volume distribution of conditioned air. A railway vehicle air-conditioning duct that supplies conditioned air generated by an air conditioner into a cabin and that extends in a vehicle length direction at a vehicle ceiling part has: a main duct; a chamber duct; a branch duct; and a guide part. The guide part is lower in height than the main duct, extends to a branch duct from the main duct or a partition wall in the main duct in a vehicle width direction, and supplies to the branch duct a portion of the conditioned air supplied to the main duct.
Abstract: A return air apparatus is provided with a ceiling template, which is mounted to an air comfort appliance unit at the ceiling of a recreational vehicle, a down draft diverter, a return air cover, and a return air grille. The ceiling template has a discharge opening and a return opening divided by an air barrier. The return air cover has a direct discharge opening and a return opening positioned below the ceiling template openings. The return air grille has a first section that communicates with the discharge opening of the ceiling template and a predetermined area of the interior of the recreational vehicle, and a second section that communicates with the return opening of the ceiling template and the interior of the recreational vehicle.
Abstract: A multi-rotor blower fan assembly for a cotton picker utilizes a plurality of separate fan enclosures each containing a fan for supplying an individual air flow to a picker unit of the picker, the fans being mounted on a common shaft for rotation therewith, with a unitary removable or openable cover or hood covering access openings of the fan enclosures. One or more of the fan assemblies can be mounted on the picker, for instance, on an existing platform on the picker chassis just rearward of the operator cab, in end-to-end relation, and rotatably driven using a common drive.

Abstract: In a vehicle air conditioner, each of cool air outlets is provided at an upper side of each seat at second and third seat lines from a most front seat so that cool air from an air conditioning unit is blown from the cool air outlets toward upper sides of the seats, respectively, and each of warm air outlets is provided at a lower side of each seat at the second and third seat lines so that warm air from the air conditioning unit is blown from the warm air outlets toward lower sides of the seats, respectively. In addition, each of suction ports is provided for each corresponding seat at the second and third seat lines so that air inside a passenger compartment is sucked from the suction ports to be returned to the air conditioning unit.
Abstract: An air conditioning system for a recreational vehicle is provided having a rooftop mounted air conditioning unit with an outlet for conditioned air and an inlet for return air and an air distribution system. The air distribution system includes ducts mounted between the roof and a ceiling of the recreational vehicle that are in communication with the outlet of the air conditioning unit. The air distribution system also includes registers mounted in openings of the ceiling to discharge the conditioned air from the ducts into various areas of the interior of the recreational vehicle. A ceiling grille is mounted at the ceiling below the air conditioning unit and has a return air grille and a closable register. The return air grille communicates the inlet of the air conditioning unit with the interior of the recreational vehicle.
