AIR HANDLING VENT CONTROL

摘要

Techniques for use with vent covers of furnace ductworks are described herein. A vent cover may include a fan to actively pull air from the ductwork and into a room at least in part in response to a number of open or closed vents in ductwork to which the vent cover is connected. Active air movement through the vent cover may lower air pressure and/or temperature within the ductwork and increase airflow through heat exchangers of the furnace, thereby compensating for zones created by closed vent covers. A system may monitor factors consistent with a furnace over-temperature event, such as furnace operation, closed vent covers, high air pressure or temperature in ductwork, etc. A fan of a vent cover may be turned on to actively draw air through a vent covered by the vent cover. The fan may turn off after conclusion of at least one of the monitored factors.

1. A method, comprising:
monitoring factors to prevent an over-temperature event of a furnace, the factors comprising a first vent cover that is closed; turning on, based at least in part on the monitored factors, a fan of a second vent cover to actively draw air through a vent covered by the second vent cover; and turning off the fan based at least in part on conclusion of at least one of the monitored factors.
