Abstract: Various technologies for monitoring operation of an air contaminant mitigation system, such as a vapor intrusion and/or radon gas mitigation system, are disclosed. For example, in one embodiment, a monitoring system includes an air contaminant mitigation system to exhaust vapors from a contaminated area to a designated area and a sensor module coupled to the air contaminant mitigation system to generate sensor signals indicative of a sensor condition of the air contaminant mitigation system. The system may also include a sensor controller to receive the sensor signals from the sensor module and generate sensor data indicative of the sensor signals. Additionally, the system may include a data server to receive the sensor data from the sensor controller, store the sensor data in a local database, and transmit information based on the sensor data to a remote computing device.

Abstract: A method for measuring pressure differences in different premises of a building, in which the pressure difference is measured using one or more sensors (2) that measure absolute pressure. The measurement results obtained from the sensors (2) are combined with information on the efficiency of the ventilation of the building, and the pressure difference caused by ventilation is mathematically separated from the measurement result by making use of information on the ventilation efficiency at any one time.

Abstract: A wall box for a ventilation system comprises a housing delimiting an interior, in which a through-flow region is defined. In the interior is arranged at least one flap arrangement having a flap arranged on a suspension mounting. For an area A of a cross section of the interior perpendicular to a flow direction, A/K>2/πr, wherein K indicates an area of an enveloping circle with smallest possible radius, which circle completely conceals the cross section of the interior. The flap of the at least one flap arrangement has at least in an open position a flap contour which in regions adjacent to a pivot axis is adapted to a cross-sectional contour of the interior in the respective region adjacent to the pivot axis.

Abstract: An illumination device and a ventilator include: a fan electrically connecting to a power transmitting port to be rotated for generating an airflow; a light-emitting device for transferring electrical power into illumination; a power storage module electrically connecting with the light-emitting device and the power transmitting port; and a control unit electrically connecting with the power storage module and the power transmitting port. The control unit determines whether the power transmitting port provides electrical power, the control unit controls the power storage module to store electrical power sourced from the power transmitting port when a result of the determination is positive, and the control unit controls the power storage module to output electrical power stored therein to the light-emitting device when the result of the determination is negative.

Abstract: A system and method for selecting a proper fan for an air flow system for mitigating radon in a building. An air flow system includes a pipe connected to an access hole extending through the center of a slab and into the underlying soil. A test hole also extends through the slab. A variable speed test fan is installed in the pipe, and a manometer is installed to measure a static pressure value of the overall system. A chart or a computer program is configured to correlate a particular speed of the test fan and a particular static pressure value when the test fan creates an initial draw at the test hole with an identification of a proper fan. The proper fan has an operating speed which is closest to the particular speed. The proper fan is then installed in place of the test fan in the air flow system.

Abstract: A dual fan apparatus for providing heated or cooled air which is compact fit within limited spaces. The dual fan apparatus includes two axial fans on opposing sides of a thermal exchange component which operate in coordination to move air in one direction at a time through the apparatus. The dual fan apparatus increases airflow and thermal transfer efficiency through the thermal exchange component.

Abstract: A system of networked local heating includes a plurality of networked local heating sources, each networked local heating source including a directional infrared (IR) radiation heat source configured to output directional IR radiation toward a remotely located target area, and a local heat source controller configured to activate the directional IP radiation heat source to output the directional IR radiation toward the remotely located target area during short duration radiative heat events. The system also includes a local heat source management system configured to log heat event requests from each of the local heat source controllers.

Abstract: A ventilation system comprising a conveying unit for conveying a supply airstream into an interior space through at least one air outlet channel, and at least one exhaust air opening which may have an adjustable opening width. The at least one air outlet channel arranged at a distance from the at least one exhaust air opening, such that an airstream is established during operation therebetween in the interior space. The ventilation system is paired with a humidifying device to supply humidity into the interior space, said humidifying device comprising a generator for generating an aerosol from a liquid with droplets sized to be carried by the airstream, and at least one aerosol outlet channel arranged in the interior space such that the aerosol is captured by the airstream. A method for conditioning an interior space using at least one or more such ventilation systems is further described.

Abstract: An air blower including a convex part protruding away from the rotation axis of an impeller. When arbitrary cross-sectional surfaces are provided by cutting the convex part in a parallel direction with the rotation axis, each point of the inner circumferential surface of the convex part, which has a maximum distance from the rotation axis, leans toward a first plate of the first and second plates, at which inlets are formed.
