本文介绍了一个双床，活性炭纤维（ACF）-乙醇吸附式制冷机的瞬态建模。这种创新的吸附式制冷机采用A-20型沥青基ACF作为吸附剂，它是一种纤维状吸附剂，与颗粒状吸附剂和粉末状吸附剂相比，具有吸附速度快、孔隙率高和易于处理的优点。使用乙醇作为制冷剂是因为乙醇对环境无害，它是一种无毒物质，而且乙醇即使在低温下也具有相对较高的蒸气压。这一创新系统有效利用了温度在60至95摄氏度之间的低温废热源沿着30摄氏度的冷却剂。我们发现，无论初始质量分布如何，ACF-乙醇吸附式制冷机都能够在三个循环或1890 s内达到相同的循环稳态。(c)2006年Elsevier Ltd和IIR。All rights reserved.
This article presents the transient modelling for a two-bed, activated carbon fiber (ACF)-ethanol adsorption chiller. This innovative adsorption chiller employs pitch based ACF of type A-20 as adsorbent which is a fibrous adsorbent having the advantages of fast adsorption rate, high porosity and ease of handling when compared with granular adsorbents and powdered adsorbents. Ethanol is used as refrigerant as it has no harm to environment, it is a non-toxic substance, moreover, ethanol has comparatively higher vapor pressure even at low temperature. This innovative system utilizes effectively low-temperature waste heat sources of temperature between 60 and 95 degrees C along with a coolant at 30 degrees C. We have found that, regardless of the initial mass distribution, the ACF-ethanol adsorption chiller is able to achieve the same cyclic-steady-state within three cycles or 1890s.
