The former is to gain refrigeration volume through the process of adsorbing adsorbate ( cryogen ) by adsorbents ; while in desiccant cooling , solid adsorbent is used to remove the moisture from the surrounding 吸附式制冷是利用固體吸附劑對(duì)吸附質(zhì)(制冷劑)的吸附過程而獲得冷量的。吸附除濕制冷是用固體吸附劑將空氣中的水蒸汽部分除去,并與蒸發(fā)冷卻等技術(shù)結(jié)合,達(dá)到制冷效果的制冷方法。
