• 中文摘要： 本文分析一種固定平板式除濕冷卻空調系統之性能。此系統中除濕器之吸附劑為矽膠，此矽膠乃被覆於底板之上，以組合成交叉平板式之除濕器，此除濕器中每兩個除濕管道中即含有一個交叉冷卻管道，而除濕器中之熱質輸送現象乃以差分法分析之，系統中冷卻器及熱交換器之性能則以其效率表示之。本文主要探討不同空氣流量、操作時間、再生溫度及除淨時間之長短對系統COP與冷卻量之影響，同時舉例說明此系統中除濕器之設計方法。
• 英文摘要： An analysis of a cross-cooled desiccant dehumidification system is performed. The heat and masstransfer process in the dehumidifier is analyzed using a two-dimensional finite-difference model. The de-humidifier has the same length in both flow directions and the adsorbent is silica gel felt. The effectivenessof the heat exchanger and the evaporative cooler are individually indicated as an input condition in thecomputer simulation. The COP and the cooling capacity are obtained for various air mass flowrates,operating periods, regeneration temperatures and purging periods. An example illustrating the design of adehumidifier is included.
