摘要
"固体吸湿剂"、"液体吸湿剂"常作为吸湿剂中的两大类型被提及。固体吸湿剂利用吸附原理,对湿空气进行除湿;液体吸湿剂利用吸收原理,使空气达到除湿的效果。而压缩空气作为一种极为干燥的空气,我们称之为"气体吸湿剂",此空气通过和湿空气混合,实现对湿空气稀释除湿的目的。同时经过压缩空气气体吸湿剂除湿后的空气可以与蒸发冷却技术相结合应用于空调中,大大提高蒸发冷却降温的效率。另外,在我国西北等干燥地区大气中存在着一种经过大自然除湿后的天然干燥空气—干空气,我们可充分利用这种气体吸湿剂,直接送入建筑物内消除室内的湿负荷,大大降低人工制冷除湿的能耗,同时充分利用"干空气能",达到尽量采用蒸发冷却天然冷源降温的效果,从而实现建筑低能耗的目的。"气体吸湿剂"是一种新的吸湿剂概念,为此,本文对术语"气体吸湿剂"进行了初步的探讨。
＂Solid desiccant＂, ＂liquid desiccant＂ is often used as a desiccant are mentioned in two major types. Solid desiccant by adsorption, dehumidify the wet air; liquid desiccant using absorption principle, allows air to reach the dehumidifying effect. While the compressed air as an extremely dry air, known as ＂ gas desiccant＂ , which is a kind of special, gaseous dry air, the air mixed with wet air, to achieve the purpose of dilution and dehu midification of wet air. At the same time the air dehumidified by the compressed air gas desiccant, can be combined with evaporative cooling technology and applied in air conditioning, greatly improving the efficiency of evaporative cooling. In addition, in Chinag northwest dry region, there exists a natural dry air which is dehumidified by the na ture - dry air, we can make full use of the gas desiccant, directly into the building to eliminate indoor humidity load, thereby greatly reducing the artificial refrigeration dehumidification energy consumption, at the same time, we can make full use of the ＂dry air energy＂, as far as possible to achieve the cooling effect for natural cold sources of evaporative cooling, to achieve the aim of low energy consumption building. ＂Gas desiccant＂ is a new concept of the desiccant, therefore, the term ＂gas desiccant＂ has carried on the preliminary discussion.
