WSURF Case 647
Energy-Efficient Device for Building Ventilation Systems
Summary
WSU researchers have developed a motorized, insulated damper system for actively injecting fresh air into a furnace system and sealing and insulating the fresh air intake duct when the furnace is not operating.
This innovative, patented design provides:
- Energy conservation
- Improved indoor air quality
- Meets UMC building code
The insulated damper blade in this motorized system insulates the furnace duct line interior from the exterior environment when in a closed position. A fan operates simultaneously with the damper blade, operating to pull air when in the on position and shut off when the damper is closed.
This "green" device provides controlled fresh air flow to the furnace system and into the building, a concept that is of considerable interest to current sustainable housing and healthy living initiatives.
Market
This innovative technology is designed for air intake in residential and small commercial forced-air furnace systems. This device would be useful in new home construction or as an upgrade in an existing building. Through energy savings, customers should expect a complete return on their investment in approximately two years.
IP Status
This technology is patented under US Patent No. 6,213,117 and available for licensing.
