  • Patent number: 7007856
    Abstract: An extended engine off passenger climate control system utilizes an advanced temperature control module in combination with modifications to the conventional heating/ventilation/air conditioning (HVAC) system to provide occupants in the passenger cabin of a hybrid electric motor vehicle with adequate heat or air conditioning for up to two minutes after the gasoline engine is turned off. A two stage orifice between the condenser and the evaporator of the air conditioning system slows the equilibration of the pressures on the high pressure side and low pressure side of the air conditioning system when the air conditioner compressor is turned off, allowing the passenger cabin to continue receiving cooling air even when the gasoline engine, and thus the compressor, is off. An auxiliary engine coolant pump circulates heated engine coolant through the heater core when the gasoline engine is turned off, thus providing heat when conditions require passenger cabin heating.

  • Patent number: 7001263
    Abstract: An air flow monitoring and control system with reduced false alarms includes an alarm sensor for monitoring air flow in a fume hood or the like, set to provide a warning if air flow drops below a predetermined amount. A local controller monitors the alarm, and disables it when the hood is set to reduced air flow, whether by a local timer or by command of a central control system. Optionally, the controller itself can operate a variable speed drive to reduce air flow on a timed basis, and the controller can communicate with facility management through a dialer or the Internet, or can interface with a central control for the facility through a facility bus.

  • Patent number: 7001266
    Abstract: Membrane roofs are susceptible to damage in high winds. Wind can lift a membrane roof from a building and cause it to tear or become damaged. The present roof vent prevents liftoff and damage by reducing the air pressure under the membrane during high winds. The present roof vent has two opposed convex domes separated by a gap. Wind blowing across the roof flows between the domes where it accelerates and creates a region of low pressure according to the Venturi effect. The lower dome has an opening at the gap so that the low pressure is applied to the space under the membrane roof. Therefore, when wind blows across the roof, the vent draws air from under the membrane and the membrane is pressed against the roof, preventing liftoff.

  • Patent number: 7001265
    Abstract: An air exhaust system comprises a chamber. The chamber has side walls, a ceiling, an attic and a roof. The ceiling and roof have air flow apertures. Provided next is a duct with upper and lower ends. A turbine fan is provided. The fan is operatively coupled to the upper end of the duct and rotatable about a vertical axis. The fan is further adapted to be self rotated as the air moves from a location in the chamber to a cooler location above the fan. Last provided is a damper. The damper is located above the lower end of the duct. The damper is moveable between closed and open orientations. The closed orientation precludes the flow of air through the duct. The open orientation allows for the flow of air through the duct.

  • Patent number: 6979258
    Abstract: In a ventilation system of a motor vehicle, a film valve can selectively open and close an air path opening defined by a housing with a rib or projection that encircles such opening. The rib can define a point contact between the film valve and the housing when viewed in cross-section. The rib geometry can include substantially straight edges in cross-section and/or can include arcuate edges. Different geometry can define the rib at different cross-sections. The point contact defined between the rib and the film valve substantially reduces noise generated when the film valve moves relative to the rib, especially when the film valve has been subjected to a harsh environment.

A louver assembly is disposed within the fascia opening and is movable between a first position substantially flush with the fascia and a second position substantially nonflush with the fascia. The louver assembly includes a housing having an inlet and an outlet. A set of louvers are secured within the housing in spaced-apart adjacent relationship and are configured to adjust the direction of air flowing through the housing. An actuator extends from the fascia adjacent the opening and is operably connected with the louver assembly. Movement of the actuator within a first range causes pivotal movement of the louvers, and movement of the actuator within a second range causes pivotal movement of the louver assembly between the first and second positions.
