1. A variable, dual mode ventilator apparatus having first and second modes of operation, said apparatus comprising:a partitioned housing forming 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, said rotatable desiccant bed contained within said housing, wherein the rate of rotation of said desiccant bed is selected dependent on the mode of operation of said apparatus, said 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 said 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 said desiccant bed to form the treated air of the second passageway; the apparatus is adaptable for conversion between the first and the second modes of operation; wherein, in the first mode, the treated air of the first passageway is of higher humidity as compared to the corresponding air to be treated and the treated air of the second passageway is of lower humidity as compared to the corresponding air to be treated and wherein, in the second mode, the treated air of one of the first and second passageways is cooler as compared to the corresponding air to be treated and the treated air of the other of the first and second passageways is warmer as compared to the corresponding air to be treated.
