Indoor air quality appliance

A self-regulating appliance operable as an air-exchanger, a humidifier, a dehumidifier, an air scrubber, and an air sterilizer, comprising:

• a cabinet defining an interior with a plurality of fluid passageways, the cabinet comprising a first inlet configured to receive a first air flow from a dwelling interior, a second inlet configured to receive a second air flow from a dwelling exterior, a first outlet configured to deliver a third air flow to the dwelling interior, and a second outlet configured to deliver a fourth air flow to the dwelling exterior;
• at least one blower fluidically coupled to the first and second outlets configured to expel the third air flow to the dwelling interior and the fourth air flow to the dwelling exterior;
• an energy exchange core fluidically coupled to the first and second inlets and outlets within the interior of the cabinet, the energy exchange core configured to transfer sensible energy between at least two air streams;
• a desiccant wheel fluidically coupled to the core and first and second inlets and outlets, the desiccant wheel configured to rotate to transfer moisture and sensible energy between at least two air streams;
• and
• a sterilization source coupled to the cabinet interior configured to emit a prescribed amount of light to kill airborne viruses.
