  • Patent number: 6926601
    Abstract: In a deodorizing apparatus for a vehicular passenger compartment, when an ignition key is off and it is determined that a density of odor components in the passenger compartment is equal to or higher than a predetermined level, it is determined whether an inside temperature inside the passenger compartment measured by a temperature sensor is equal to or higher than a predetermined temperature, which is suitable for separating odor components adhered to the passenger compartment. When it is determined that the inside temperature is equal to or higher than the predetermined temperature, a deodorizing operation is performed by a deodorizing means. When it is determined that the inside temperature is lower than the predetermined temperature and it is not assumed that the inside temperature naturally increases to the predetermined temperature, the passenger compartment is heated by a compartment heating device so that the inside temperature reaches the predetermined temperature.

  • Patent number: 6910961
    Abstract: Personal air supply devices integrated with chairs are adapted for use in conjunction with building or vehicle ventilation systems. The personal air supply devices include ducts, a tube and a nozzle arranged to direct a portion of the air from the building or vehicle ventilation system at the facial zone of a person sitting in the chair. The personal air supply devices include airflow regulating devices for regulating the flow of air through the nozzle. The tubes and nozzle are configured to release air from the ventilation system very close to the nose and mouth of a person in the chair to prevent mixing with ambient air and maximize the cooling and refreshing effect of the conditioned air. The building or vehicle ventilation system may be operated at lower ventilation rates without causing discomfort to persons provided with personal air supply devices.

  • Patent number: 6908039
    Abstract: A heat exchange system and method for heating outside air provided to a structure are disclosed. The system uses and recovers heat from waste products that are being exhausted from the structure. A heated products source generates heated waste products as a result of combustion. An exhaust duct passes the heated waste products through a heat exchanger before exhaustion from the structure. An intake duct that supplies fresh outside air to the structure also passes through the heat exchanger. The heat exchanger couples the exhaust duct and the intake duct and transfers otherwise unused heat from the waste products to the outside air to increase the overall efficiency of the heated product source.

  • Patent number: 6902474
    Abstract: An air duct outlet that allows a user to redirect an air stream within a wide range of directions includes a housing having a planar first wall and a convexly-curved second wall in adjacent, spaced-apart relationship and that define an air passageway having an inlet and a flared outlet. A vane is pivotally attached within the air passageway and is movable within a range of positions that are increasingly transverse to the first wall. An air stream flowing through the air passageway is deflected by an amount that increases with each position of the vane in the range such that the air stream adheres to a portion of the second wall by an amount that increases with each position of the vane in the range and such that the air stream exits from the outlet in a direction that is increasingly transverse to a direction normal to the outlet.

  • Patent number: 6899615
    Abstract: An air duct system includes a conical fabric filter disposed within a cylindrical air duct. In some embodiments, both the filter and the air duct are inflatable. A fabric collar and a pair of zippers not only allow the filter to be readily removed for cleaning, but also allow the air duct system to continue operating with the filter removed. Pleats can provide the filter with more surface area, and the pleats can be interconnected in an alternating pattern to inhibit the filter from over-inflating.
