Fresh air building and home ventilation apparatus and methodologies

An integrated fan and sensor combination for use in a system to provide comfort ventilation of a building, comprising:

• a variable speed fan assembly mounted within a housing configured to duct outside air along an air flow path through the housing into an inside space of the building in response to fan control signals;
• an air flow sensor module comprising a substrate having a heated thermistor disposed along the axis of the air flow path and a reference thermistor disposed in the air flow path in a spaced-away relationship with the heated thermistor;
• first and second respective sensors for air temperature and relative humidity, disposed in the air flow path within the housing;
• and
• a user-programmable controller, including a control panel and a display, the controller coupled to the variable speed fan, the sensor module, and the respective sensors for air temperature and relative humidity, for generating the fan control signals to control the variable speed fan responsive to:
• user-defined minimum and maximum limits, entered via the control panel, for the air temperature and relative humidity of the outside air admitted to the housing via the fan and conducted into the inside space;
• and
• user-defined minimum and maximum limits, entered via the control panel, for the volume of air flow (CFM) supplied by the variable speed fan and conducted into the inside space;
• wherein
• the air temperature, relative humidity, and volume of the air flow into the inside space are maintained within the user-defined minimum and maximum limits to provide the comfort ventilation;
• and
• the volume of air flow (CFM) is displayed to the user on the display to confirm it is within the minimum and maximum user-defined limits for the desired comfort ventilation.
