Claim:
A method of maintaining an enclosed space in a building structure free of fungi comprising the steps of: providing a housing having an inlet end and an outlet end and a passage extending between the inlet end and the outlet end; positioning the housing within the enclosed space; positioning a blower unit proximate the outlet end of the housing; positioning an evaporator in the passage between the blower unit and the housing inlet end; positioning a condenser in the passage between the evaporator and the blower unit; positioning a compressor in the passage between the evaporator and the condenser; operatively connecting the compressor to the evaporator and the condenser within the passage to form a closed circuit refrigerant loop totally contained within the passage; and positioning a germicidal device in the passage between the condenser and the blower unit, the blower unit functioning to draw fungi infected air from the enclosed space, draw it through the inlet end of the housing, pass it successively over the evaporator, the compressor, the condenser and the germicidal device, and discharge the germicidally treated air into the enclosed space.
