一、设计计算的必要性长期以来,在洁净室的设计中不太注意计算,一般采用经验数据,造成的后果是浪费较大。有的人宣称,设计国内3000级(相当于209_b标准10万级)的洁净室非60次换气不做。从国内外发表的一些数据和作者实测许多工程的结果可以看出,实际达到的洁净度等级往往高出设计要求一个数量级。目前空气净化工程越来越多,如不注意精打细算和节能就会造成较大浪费,因此,对洁净室设计进行必要的计算是完全应该的了。当然,在估算或
First, the necessity of design calculations For a long time, in the design of clean rooms, less attention was paid to the calculations. Generally, empirical data was used, resulting in a wasteful result. Some people claimed that the design of domestic 3,000 (equivalent to 209_b standard 100,000) clean room does not do 60 times ventilation. From some data published at home and abroad and the results of the author’s actual measurement of many projects, it can be seen that the cleanliness level actually achieved is often an order of magnitude higher than the design requirement. At present, more and more air purification projects, if you do not pay attention to careful calculation and energy saving will cause greater waste, therefore, the necessary calculation of the clean room design is entirely appropriate. Of course, in the estimation or
