1. A kitchen exhaust system, comprising:
a housing at least partially defining a mixing chamber and having:
a vapor intake port adapted to fluidly couple to a hood that collects grease-laden vapors from a cooking area effective to receive the grease-laden vapors from the cooking area;
a cold air intake adapted to fluidly couple to a cold air induction system that produces cold air effective to receive the cold air produced by the cold air induction system;
one or more walls positioned to create turbulence of air flow formed from the cold air and the grease-laden vapors, wherein the cold air and the turbulence of the air flow separate at least a portion of grease from the grease-laden vapors;
a drain positioned at a bottom region of the mixing chamber to collect the at least the portion of the grease from the grease-laden vapors that has been separated;
a vapor exhaust positioned at a top region of the mixing chamber distal to the bottom region to allow vapors to exit the mixing chamber, the vapors having the at least the portion of the grease from the grease-laden vapors removed; and
funneling walls positioned at the cold air intake and angled toward one another in the chamber.
