Abstract: Implementations of airflow capture hoods may include a central support coupled with a plurality of ribs configured to support a bottom end of a capture hood in an open position. The central support may be coupled with a plurality of poles configured to support an upper end of a capture hood in an open position.
Abstract: Implementations of an airflow capture hood flow control ring may include a flexible ring including a toroidal shape configured to couple around a base of an airflow capture hood. The ring may be configured to permit an airflow sensor coupled to the airflow capture hood coupled to an inlet to measure a flow of air into the inlet with at least 90% accuracy.
Abstract: An apparatus, system, and methods for measuring environmental parameters are disclosed. The apparatus, system and methods can be used for a variety of applications, including HVAC air balancing and building commissioning. The system includes a variety of wireless sensing modules and wearable modules for control. display, and storage. Parameters measured include air and water temperature, pressure. velocity, and flow. Also included are sensors for light intensity, CO concentrations, and CO2 concentrations.
Abstract: Implementations of an airflow capture hood plate may include a plate including a plurality of openings therethrough. The plate may be configured to couple to a hood to guide airflow through the hood when the hood is placed over a diffuser of a heating, ventilation and air conditioning (HVAC) system and the plurality of openings in the plate may be configured to align with a plurality of ribs of a grid in the hood.
