1. A bi-directional ceiling mounted air diffuser for discharging supply air into a room comprising:

  • output means for varying the orientation and size of an air diffuser discharge opening;

    means for sensing the temperature of the supply air;

    linkage operatively connecting said supply air temperature sensing means to said output means so that when said supply air temperature is cool, said linkage operates to open said output means and direct said supply air generally parallel to the ceiling of said room, and when said supply air temperature is warm, said linkage operates to open said output means and direct said supply air generally vertically downward into said room, where said output means varies the size of said discharge opening so that the size of said discharge opening is smaller for warm supply air than for cool supply, thereby increasing the discharge velocity of a volume of warm supply air over the discharge velocity of a like volume of cool supply air.
