Abstract: A method of controlling ventilation of air within a local environment of a structure includes determining an indoor air quality level based on signals from one or more monitoring devices located in the local environment. In indoor air quality system includes one or more monitoring devices that determine the indoor air quality level and activate one or more appliances based on the readings from the one or more monitoring devices.

Abstract: A mounting bracket mountable to the underside of the cabinet prior to the range hood and configured to engage and support the range hood as the range hood is secured to the cabinet. The mounting bracket having a support feature engagable to the range hood to hold the range hood proximate the cabinet while fasteners are sunk to secure the range hood to the cabinet. The mounting brackets are pre-positioned on the cabinet such that range hood is aligned with the cabinet when the range hood is supported by the support feature. The smaller mounting brackets can be more easily mounted in the proper position on the cabinet then the larger range 10 hood speeding the installation process and reducing errors.

Abstract: A venting system in accordance with the present disclosure includes a ventilation fan and one or more sensors coupled to the ventilation fan. The ventilation fan is positioned to vent air from an indoor environment. The sensors are positioned to monitor conditions in the indoor environment and selectively operate the ventilation fan to condition air in the indoor environment.

Abstract: A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.

Abstract: A range hood configured to direct exhaust from a cooktop toward a blower assembly. The blower assembly and the range hood are configured to be attached to cabinetry having a predetermined opening between at least two cabinets included in the cabinetry. A barrier is placed around the predetermined opening to guard against damage to surfaces around the range hood.

Abstract: A air inlet for an air handling unit includes an intake grate that extends around a central axis and is configured to admit an airflow therethrough. The air inlet further includes an outlet duct arranged to lie along the central axis and positioned radially inward of the intake grate. The air inlet further includes a debris collection housing.

Abstract: An air inlet for an air handling unit includes a duct defining a passageway leading to the air handling unit.

Abstract: A system and method for obtaining environmental data—namely air quality information—from various devices contained within a structure is disclosed herein. The various devices contain sensors that can obtain environmental data, which is then analyzed by the system to determine if any level of a component within the data is outside of a predefined threshold range. If the system determines that the level of the component is outside of the predefined threshold range for that given component, the system will carry out certain steps in order to bring the level within the predetermined threshold range. These steps include selecting the appropriate appliance and the proper operating conditions to most efficiently bring the level back within the predetermined threshold range. Once the system has determined that the level is back within the predetermined threshold range, the system will instruct the selected appliance to turn OFF.

Abstract: A sensor-enabled range hood can be used with a cooking appliance. Information from multiple sensors can be used to determine whether abnormal or hazardous conditions are present, such as when unattended cooking is detected. A local indication or a remote notification can be generated in response to one or more conditions. A control signal to control a cooking appliance or range hood can be issued in response to one or more conditions. A remediation signal to address an actual fire present can be issued, such as to trigger fire remediation.
