Climate smart fan ventilation

A ventilation supply apparatus for affixing at a position relative to a building, comprising:

• a segment of duct having a length between 6 and 24 inches;
• a ventilation exterior-to-interior supply fan located within an interior of the segment and for directing air through the interior;
• an electronic controller coupled to the segment, the controller comprising:
• circuitry for receiving a signal representative of exterior air temperature from air exterior of the building;
• and
• circuitry for receiving a signal representative of exterior relative humidity from relative humidity of air exterior of the building;
• circuitry for providing a first control signal to enable the ventilation exterior-to-interior supply fan to a first speed in response to at least one of:
• the signal representative of exterior air temperature indicating dissatisfaction of a first range of acceptable temperature;
• or
• the signal representative of exterior relative humidity indicating dissatisfaction of a first range of acceptable relative humidity;
• and
• circuitry for providing a second control signal to enable the ventilation exterior-to-interior supply fan to a second speed, greater than the first speed, in response to both:
• the signal representative of exterior air temperature indicating satisfaction of the first range of acceptable temperature;
• and
• the signal representative of exterior relative humidity indicating satisfaction of the first range of acceptable relative humidity;
• and
• wherein the circuitry for providing the first control signal and the circuitry for providing the second control signal provide the first control signal and the second control signal irrespective of air temperature interior to the building and irrespective of relative humidity of air interior to the building.

A ventilation supply apparatus for installation into a building having a wall, comprising:

• a singular cabinet, comprising:
• a frame for attaching through the wall, wherein the frame comprises:
• a first inlet coupled to an exterior of the wall for receiving air sourced from an area exterior of the building;
• a second inlet for receiving air sourced from an area interior of the building;
• and
• an outlet coupled to an interior of the wall for providing an air mixture directly to the interior of the building, the mixture comprising the air sourced from an area exterior of the building and the air sourced from an area interior of the building
• a fan for drawing air into the first inlet and the second inlet;
• circuitry for receiving a signal representative of exterior air temperature from air exterior of the building;
• circuitry for receiving a signal representative of exterior relative humidity from relative humidity of air exterior of the building;
• circuitry for providing a first control signal to enable a ventilation exterior-to-interior supply fan to a first speed in response to at least one of:
• the signal representative of exterior air temperature indicating dissatisfaction of the first range of acceptable temperature;
• or
• the signal representative of exterior relative humidity indicating dissatisfaction of the first range of acceptable relative humidity;
• and
• circuitry for providing a second control signal to enable the ventilation exterior-to-interior supply fan to a second speed, greater than the first speed, in response to both:
• the signal representative of exterior air temperature indicating satisfaction of the first range of acceptable temperature;
• and
• the signal representative of exterior relative humidity indicating satisfaction of the first range of acceptable relative humidity;
• and
• wherein the circuitry for providing the first control signal and the circuitry for providing the second control signal provide the first control signal and the second control signal irrespective of air temperature interior to the building and irrespective of relative humidity of air interior to the building.
