摘要
本文阐述了电子行业洁净室空调的特点,介绍了目前电子行业常采用的干盘管-FFU洁净空调系统并对该系统的空气处理过程进行了分析。分析计算表明,由于电子行业洁净室空调冷负荷巨大,可能导致干盘管-FFU洁净空调系统的换气次数也很大,甚至超过按室内允许含尘浓度计算得出的换气次数。针对干盘管-FFU洁净空调系统的特殊性,本文提出了工程设计的方法和步骤,并介绍了工程设计的有关参数。本文归纳的设计方法和步骤可应用于实际工程设计中。
In this paper, the characteristic of cleaning room in the electronic industry was expounded, dry coil and FFU cleaning air conditioning system was introduced, and air conditioning course was analyzed. The results showed that the huge cooling load of cleaning room will probably result in the increasing of the air circulation ratio of dry coil and FFU cleaning air conditioning system,or even make the air circulation ratio exceed the allowable level decided by dusty concentration. Based on the analysis, engineering designing steps and the parameters especially for dry coil and FFU cleaning air conditioning system in designing cleaning room were introduced. These designing steps can be applied in engineering.
