Abstract
A ventilation system for urging flue gases from an exhaust source through an exhaust conduit has an exhaust outlet for venting the gases and an exhaust inlet communicating with the exhaust source. A blower fan is provided for creating a positive air flow away from the exhaust inlet to urge the flue gases through the exhaust conduit and out of the exhaust outlet. A blower pipe channels air from the blower fan into the exhaust conduit past the exhaust inlet so as to create a venturi effect to draw exhaust from the exhaust inlet into the exhaust conduit. Duct work may be provided so that the blower fan draws fresh air from the ambient, namely from outside the structure housing the exhaust sources, rather than from inside the structure.
Claims17
A ventilation system for venting exhaust from a plurality of exhaust sources housed within a structure comprising:
- an elongate exhaust conduit having an exhaust outlet at an upper portion open to atmosphere and a plurality of exhaust inlets at an opposed lower portion thereof within said structure, each exhaust inlet communicating with a respective exhaust source;
- a blower member housed within said structure and communicating with said lower portion of the exhaust conduit for forcing non-combusted air through said exhaust conduit for creating a positive air flow therethrough to urge said exhaust from said exhaust inlets to said exhaust outlet;and
- means for controlling operation of said blower member in concert with the operation of any one of said exhaust sources.
In a ventilation system for urging flue gases from at least two exhaust sources housed within a structure through an elongate exhaust conduit having an exhaust outlet at a first end thereof for venting said gases and a plurality of exhaust inlets at an opposed second end within said structure, each exhaust inlet communicating with a respective one of said exhaust sources, the improvement comprising:
- a blower housed within said structure communicating with said second end of the exhaust conduit, but not with any of said exhaust sources, for drawing fresh air into said exhaust conduit for creating a positive air flow away from said exhaust inlets to urge said flue gases through said exhaust conduit and out of said exhaust outlet, and means for activating said blower in concert with the operation of said exhaust sources.
