Patent ID: 7013969

Claim:
A displacement ventilation, low noise level, mixed air, HVAC system for ventilating an enclosed room of a commercial or educational facility, where the system provides displacement ventilating air to said room at noise levels not exceeding about 35dBA, said system comprising: a.) a central HVAC air handling unit within said facility remote from said room, said unit including first duct work for transmitting conditioned air from said unit to said room, second duct work for receiving and transmitting return air from said room to said unit, means for mixing fresh air from the exterior of said facility with a portion of said return air, where said unit further includes means to control the temperature of the conditioned air to be transmitted to said room; and, b.) an air displacement terminal housing in proximity to said room in communication with said first duct work, a complementary outlet for said first duct work, said terminal housing further including high velocity nozzles with the conditioned air from said first duct work forced there through to create mechanical energy to induce ambient air flow, an intake outlet for transmitting induced air from said room, where said induced air mixes with said conditioned air passing through said high velocity nozzles, said mixed air being delivered through a second outlet into said room in a displacement manner.
