System and Method For Air Replacement and Positive Air Pressure Isolation

A system for reducing airborne contamination within a home comprising:

• a housing defining the structure of the system and configured to fit within a window of the home;
• an adjustable frame extending around at least part of the housing and configured to expand to at least one dimension of the window;
• a system inlet;
• a system outlet;
• a variable-speed fan configured to operate at a speed;
• a motor controller in communication with the fan and configured to control the speed of the fan;
• a solid state anemometer configured to monitor an air pressure differential between the system inlet and the system outlet;
• a closed-loop controller in communication with the motor controller and the solid state anemometer, wherein the closed-loop controller is configured to vary the speed of the fan based on the pressure differential between the inlet and outlet of the system;
• and
• a germicidal radiation chamber located within an airflow path in the air-pressure control system, the germicidal radiation chamber including at least one UV light source and configured to sterilize the air as it passes through the airflow path, the sterilized air displacing an equal volume of contaminated air within the home.

A method for reducing airborne contamination within a home comprising:

• installing an air-pressure control system within a window of the home, the air-pressure control system including:
• a system inlet,
• a system outlet,
• a variable-speed fan configured to operate at a speed,
• a motor controller in communication with the fan and configured to control the speed of the fan,
• a sensor configured to monitor an air pressure differential between the system inlet and the system outlet,
• a closed-loop controller in communication with the motor controller and the sensor, wherein the closed-loop controller is configured to vary the speed of the fan based on the pressure differential between the inlet and outlet of the system, and
• a germicidal radiation chamber located within an airflow path in the air-pressure control system, the germicidal radiation chamber including at least one UV light source;
• drawing air from outside the home through the system inlet and the airflow path, the germicidal radiation chamber sterilizing the air as it passes through the airflow path;
• and
• introducing the sterilized air into the home through the system outlet, the sterilized air displacing an equal volume of contaminated air within the home.
