  • Patent number: 3999707
    Abstract: An air conditioning system comprising a room to which conditioned air having temperature and volume parameters is delivered. Temperature sensing means is provided for sensing the temperature of the air in the room. Air supply means responsive to the sensing means is provided in an air supply duct. Damper means is also mounted in the duct for varying the effective area of the opening of the duct. A regulating means is provided for controlling the damper to vary the air velocity in accordance with a constant value for the expression Ar.1.sup.-.sup.3/2, where Ar is the Archimedean number, and 1 represents the effective area of the opening. The temperature sensing means also controls the volume parameter of the air supply which air supply has a constant temperature parameter.
