摘 要:医院洁净室空调风量参数对灰尘与细菌数量影响极大,影响风量的主要因素包括过滤器阻力、
风管沿程阻力和风管部件形式造成的阻力,在当前设计中,由于风管部件形式通常要在施工中才能明确,风
管部件造成的阻力因素主要依赖于设计人员的经验确定,因设计不足导致的问题影响深远。通过试验收集不
同部件形式下的风量衰减数据,以检查某医院组合空调设计参数是否符合要求,实证结果得到各方认可。 关键词:医院洁净室;净化空调;风量衰减;实证研究

abstract: The air volume parameters of the air conditioning in the clean room of the hospital
have a great impact on the dust and bacteria quantity. The main factors affecting the air volume
include the resistance of the filter, the resistance along the air duct and the resistance caused by the
form of the air duct components. In the current design, the resistance factors caused by the air duct
components mainly depend on the experience of the designers, and the problems caused by inadequate
design have a far-reaching impact. Since the form of air duct components is usually clear in the
construction period, this paper collects the air volume attenuation data of different component forms
through experiments, and uses them to check the design parameters of the combined air conditioning of
a hospital. The empirical results are recognized by all parties, avoiding the occurrence of losses, and
the data can also provide reference for similar design. Keywords:
hospital clean room; purifying air conditioner; air volume attenuation; empirical research

( 3)数值计算数据表明,在超浅埋小净距隧道
群开挖过程中,随着钢纤维掺量的增大,围岩变形和
围岩结构受力均有逐渐减小的趋势,当纤维掺量为
35 kg/m
