Abstract
According to the invention, a first air stream is directed over a first surface of a heat exchange member. The first surface includes a dry area and a moist area. The first stream is directed primarily over the dry area followed by the moist area. A second air stream is directed over a second surface of the heat exchange member perpendicular to the first stream. The second surface is opposite the first surface and has a dry region that is opposite the moist area of the first surface and a moist region that is opposite the dry area of the first surface. The second stream is directed over the dry region followed by the moist region. When the first stream is directed over the first surface, it will be cooled without changing its moisture content due to the cooling of the heat exchange member caused by the second stream passing simultaneously along the moist region on the opposite side. Since the second stream has a temperature lower than that of the ambient environment (the second stream being cooled prior to reaching the moist region by passing along the dry region), when the water evaporates into the second stream from the moist region, the second surface will be cooled to the wet bulb temperature of the second stream. However, since the second stream has been pre-cooled, its wet bulb temperature will be lower than the wet bulb temperature of the ambient air.
