Forced climate ventilator

A method for ventilating a building, comprising:

• transferring air wholly within the building via a duct extending between an attic, comprising an enclosed space immediately below a roof separating the attic from atmosphere and above an intermediate occupiable portion of a building, and a lowermost portion of the building separating the intermediate occupiable portion of the building from earth, while bypassing said intermediate occupiable portion of the building;
• providing operational power to a first fan exhausting air from within the attic to the outside of the building;
• and
• providing operational power to a second fan forcing air through said duct and along a lowermost stratum of the attic.

A forced climate ventilator, comprising:

• an exhaust fan having an intake orifice positioned to extract and to exhaust to atmosphere air drawn from a first enclosed space located immediately below the roof of a building and above an occupiable portion of the building;
• a duct having a first orifice positioned within the first enclosed space and having a second orifice positioned within a second enclosed space providing a closed continuous conduit extending between the first enclosed space and said second enclosed space with a first section of said duct being positioned within said first enclosed space perforated by a first orifice and a second section of said duct being positioned within said second enclosed space providing a second orifice accommodating passage of air from the second enclosed space and into said duct, said second enclosed space being located below the occupiable portion of the building and separating the occupiable portion from earth and having a plurality of openings to atmosphere, said duct accommodating transfer of air between the first and second enclosed spaces;
• a duct fan having an intake side connected to said first orifice to draw air through said duct from said second enclosed space and having a discharge side positioned within said first enclosed space separate and spaced-apart from said exhaust fan to exhaust the air along a lowermost stratum of the first enclosed space;
• and
• temperature sensing means for controlling application of operational power to said exhaust fan and to said duct fan whenever the temperature in the first enclosed space exceeds a predetermined temperature.

• first fan having an intake orifice positioned to extract and to exhaust to atmosphere air drawn from a first enclosed space located immediately below the roof of a building and above an occupiable portion of the building;
• a duct having a first orifice positioned within the first enclosed space and having a second orifice positioned within a second enclosed space providing a closed continuous conduit extending between the first enclosed space and said second enclosed space with a first section of said duct being positioned within said first enclosed space perforated by a first orifice and a second section of said duct being positioned within said second enclosed space providing a second orifice accommodating passage of air from the second enclosed space and into said duct, said second enclosed space being located below the occupiable portion of the building and separating the occupiable portion from earth and having a plurality of openings to atmosphere, said duct accommodating transfer of air between the first and second enclosed spaces;
• a second fan having an intake side positioned to draw air through said duct from said second enclosed space and a discharge side positioned to discharge the air drawn through said duct along a lowermost stratum of the first enclosed space;
• temperature sensing means for controlling application of operational power to said first fan and to said second fan whenever the temperature in the first enclosed space exceeds a predetermined temperature;
• and
• humidity sensing means for deactivating said second fan whenever the relative humidity within the first enclosed space exceeds a predetermined value.

• a second fan positioned to draw air through said duct from said second enclosed space and to discharge the air drawn through said duct along a lowermost stratum of the first enclosed space;
• and
• control means for activating said first fan when the temperature within the attic exceeds a predetermined temperature, and for activating said second fan when the temperature within the first enclosed space exceeds said predetermined temperature and humidity within the building is less than a predetermined value.
