Abstract: A window replacement panel including an air conditioning vent incorporated into it. A window assembly may be attached to a decorative panel with a vent disposed on a first side, and a coupling for an AC duct on an opposite side. The window may be a single, double pane, insulated, uninsulated or the like. The panel may be clad with material to harmonize with the building exterior, and the exterior vent presents a pleasing appearance. The combination of window and panel may be sized to replace an existing window, or may be used in new construction.

Abstract: A specially designed rotation speed controller for fans, in addition to basic components like variable resistor, the controller has also been equipped with special components such as TRIAC, micro limit switch, and glass tube fuse, which allows said controller to precisely control the on/off status and the rotation speed of the fan, and the controller also provides power-off protection against power overload.

Abstract: A heating door comprises a frame. A first panel is mounted to the frame. A second panel is mounted to the frame. A sheet is disposed between the first and second panels. The sheet defines an inner section between the first panel and the sheet and an outer section between the second panel and the sheet. At least one heating mechanism is arranged in at least one of the first and the second section.

Abstract: An air conditioner having a partition for partitioning the inside thereof into indoor and outdoor sections with an intake port. A damper is provided at the intake port so that an outdoor air introduction path of the outdoor section and an outdoor air discharge path are cut off when introducing outdoor air by opening the damper. Air the outdoor air introduction path is guided into the indoor section.

Abstract: The conventional sun visor of a vehicle is provided with a fan system including a heater for defrosting and defogging the vehicle windshield. The fan system includes a fan subassembly body mounted in an opening in the sun visor by a retainer subassembly including first and second retainer frames having flanges insertable into the fan subassembly body for securing it in the visor opening. First and second grills are mounted over the faces of the subassembly body by mechanical fasteners which extend through the body and retainer frames. An electric heating element is mounted on at least one of the grills for heating the airstream geneated by the fan of the fan subassembly. The fan and heating element are selectively powered by the vehicle electrical system through an on-off switch.

Abstract: A flexible sheet member is mounted to an interior surface of a vehicular windshield, with the sheet member including a serpentine resistance heater directed therethrough in electrical communication with the associated vehicle. A rheostat effects selective heating in the resistance element. Further, a modification of the invention includes directional air conduits mounted to an interior surface of the sheet member to direct heated air within the passenger compartment, wherein the tubes include conduits, and the conduits each selectively mount a cap member at an upper terminal end thereof, wherein each cap member includes a pivotally mounted directing tube to selectively direct heated air throughout the vehicular passenger compartment.
