    • The present invention describes methods and apparatus for controlling the humidity of air supplied to cooling coils on a gas turbine powered ship through a dynamic desiccation system. The system passes supply air through a desiccant wheel, which dries and concomitantly heats the supply air. This supply air stream is then passed through a rotatable thermal wheel, wherein heat is transferred from the dry supply air to an exhaust-air mixture, thereby conditioning the supply air for delivery and circulation to a plurality of cooling-coil units in a plurality of compartments. The exhaust air from the compartments is first mixed with some of the treated supply air to lower the absolute humidity to a value needed for effective regeneration of the desiccant wheel. An evaporative cooler then conditions the exhaust-air mixture for effective cooling of the supply air in the thermal rotor, which also serves as an air preheater for desiccant regeneration. The exhaust-air mixture is then heated to the desiccant regeneration temperature by passing the preheated exhaust air through a heat exchanger supplied with gas-turbine waste heat. After this heated exhaust-air mixture regenerates the desiccant wheel by fully drying out the desiccant on the wheel, it is expelled from the fan room.
    • 本发明描述了通过动态干燥系统控制供应到燃气轮机动力船上的冷却盘管的空气湿度的方法和装置。 系统通过干燥剂轮供给空气,干燥并伴随着加热供气。 然后,该供应气流通过可旋转的热轮,其中热量从干燥的供应空气传递到排气混合物,从而调节供给空气以将其输送和循环到多个冷却盘管单元 隔间 首先将来自隔室的废气与一些经处理的供应空气混合,以将绝对湿度降低到有效再生干燥剂轮所需的值。 然后,蒸发冷却器调节排气混合物以有效地冷却热转子中的供应空气,热转子也用作用于干燥剂再生的空气预热器。 然后通过将预热的排气通过供应有燃气轮机废热的热交换器将废气混合物加热至干燥剂再生温度。 在这种加热的排气混合物之后,通过将干燥剂完全干燥在车轮上再生干燥剂轮,它从风扇室排出。
