A SYSTEM FOR DIRECTING AND CONTROLLING TWO SEPARATE STREAMS OF AIR TO A KITCHEN

摘要

A method of directing two streams of air, a conditioned stream and an unconditioned stream, into a kitchen having an exhaust hood through which air is exhausted from the kitchen, the method comprising: a. directing the conditioned air stream into the kitchen and out an outlet in a vicinity of the exhaust hood; b. directing the unconditioned air stream into the kitchen and out an outlet positioned generally between the exhaust hood and the outlet for the conditioned air stream; c. controlling the velocity of one or both air streams such that a velocity of the conditioned air stream equals or exceeds a velocity of the unconditioned air stream; and d. wherein controlling the velocity of the one or more air streams includes varying a speed of a fan utilized to move either the unconditioned or conditioned air streams or adjusting a damper in a conduit through which one of the air streams passes.
