[ What is claimed is:] [9.] A method of operating a ventilator which includes first and second parallel air treatment passageways in counterflow arrangement, with each of the first and second air treatment passageways having an inlet for intake of air to be treated and an outlet for exhaust of treated air; and a rotatable desiccant bed having a selectable rate of rotation, the rotatable desiccant bed forming a first sector in the first passageway and a second sector in the second passageway, whereby the air to be treated in the first passageway contacts the first sector of the desiccant bed to form the treated air of the first passageway and the air to be treated in the second passageway contacts the second sector of the desiccant bed to form the treated air of the second passageway, said method including;a) a first mode of operation comprising the steps of:contacting the first sector of the desiccant bed with high humidity air to remove moisture from the air to be treated to form dehumidified treated air, andcontacting the second sector of the desiccant bed with air to remove moisture from the desiccant and to form treated air of increased moisture content andb) a second mode of operation comprising the steps of:contacting the first sector of the desiccant bed with air to be treated of a first selected temperature to heat the desiccant and to form treated air of reduced temperature, as compared to the air to be treated, andcontacting the second sector of the desiccant bed with air to be treated of a second selected temperature to form treated air of increased temperature as compared to the corresponding air to be treated.
