Solar Window Air Heaters by Solar Infra Systems
How they work:
WITH SOUTHERN EXPOSURE
Interior cool air is drawn through the lower air intakes by the solar powered
fan. The collector cells are heated by infrared energy from the sun. Through
convection, the air passes through the collectors and retains the barrier heat.
The air then rises to the next collector and repeats the process, adding to the
collected heat. The air temperature continues to rise as it passes through
each collector.
Under good winter sun conditions, up to 20º F (11º C) may be added to the
ambient temperature, with air flow at 30 cubic feet per minute - providing
supplimentary heat for a 150 sq.ft. space.
