I claim: 1. 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. 2. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 1, including a heat transfer coil in communication to said intake outlet to control the temperature of the induced air through said intake outlet prior to said mixing. 3. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 2, wherein the velocity of the mixed air through said second outlet is no greater than 100 fpm. 4. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 2, wherein said heat transfer coil may be operated in heating and cooling modes. 5. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 4, wherein said heat transfer coil, when operating in a cooling mode, includes a continuous chilled water supply, where said water supply is maintained at a temperature of at least one degree above the dew point of said room to prevent any condensation within said unit. 6. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 1, wherein said room includes a floor and a ceiling, and said second outlet is located near said floor to induce an ambient air flow into said room. 7. The displacement ventilation, low noise level, mixed air, HVAC system according to claim 6, wherein said room further includes a perimeter wall, and said air displacement terminal housing is located within said wall.
