医院洁净空调风量在管道中的衰减实证研究

Empirical Study on the A ir V olume A ttenuation in Pipes of Hospital Clean A ir Conditioning

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。

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.
