Abstract
Abstract An improved adiabatic saturation cooling machine of the opencycle type and method of operation in which the capacity of the machine is increased by routing by-pass streams of air through either the S-wheel alone or both the S- and the L-wheel. The amount of these by-pass streams are from 0 to 100 percent that of the main exhaust stream of air passing from the room through the S-wheel. In the first embodiment the by-pass air is outside air and is directed to the regenerative ''''side'''' of the S-wheel. Such a by-pass stream ranging from 95*F to 80*F will cool the air from the S-wheel an additional 2.6* to 5.9*F below that capable by the room air exhaust stream alone. The outside air by-pass stream may be passed directly through the S-wheel or pretreated by passing through an E-pad. In the second embodiment, where there is sufficient air supplied to the burner section to regenerate the L-wheel, a portion of the primary room exhaust air stream is recirculated as a by-pass stream to the input face of the L-wheel. A third embodiment is directed to incoming air bypassing the E-pads from the cooling side of the S-wheel. A fourth embodiment is directed to a return by-pass for directing the first stream of incoming L-wheel air back out the regenerative ''''side'''' of the L-wheel.
