Abstract
An exhaust system includes a ventilated ceiling component with multiple surfaces and recesses. Each recess has an exhaust intake, the recesses being distributed over an area of a ceiling that has a perimeter adjacent the recesses. The perimeter has a jet register located below the exhaust intake and configured to generate jets, a first of the jets being directed toward and located below at least one of the exhaust intakes and a second of the jets being directed substantially vertically downward. The perimeter further has a displacement ventilation register.
Claims10
An exhaust device, comprising:
- a housing having a height that is no more than one tenth of its width;
- the housing having surfaces defining at least one recess having an exhaust intake within the recess for receiving fumes captured in the recess and drawing the fumes out of the recess;
- the housing having a perimeter that extends around an entirety of the at least one recess, the perimeter having a jet register located below the exhaust intake and configured to generate jets along an entirety of the perimeter, a first of the jets being directed toward the exhaust intake and located below it and a second of the jets being directed substantially vertically downward;
- lower edges of a portion of the housing containing the exhaust intake and portion of the housing containing the jet register being substantially vertically aligned;
- the surfaces defining each of the at least one recess forming a surface with a light source located adjacent the jet register;
- the first of the jets terminating at or immediately short of the exhaust intake;
- the second of the jets terminating above 1.8 meters above a floor level;
- a fume source located below the housing;
- the light source including a light diffuser, lamp cover, or lens and being located adjacent the first of the jets, which is horizontal, so that the first of the jets keeps it clean whereby the first of the jets does double duty by helping to trap fumes by guiding pollution-containing plumes from the fume source, and keeping the light source clean;
- and
- an edge of the fume source being positioned to form at least a 20 degree angle from vertical with the jet register such that all of the fume source lies below the at least one recess.
