纺织车间空调系统最小新风量的研究

Research of Air Conditioning System Minimum Fresh Air in Textile Workshop

研究纺织车间空调系统最小新风量的确定方法。分析了现有两种纺织车间空调系统最小新风量的确定方法及出现的问题,在此基础上,引入室内空气清新度的概念,通过综合考虑纺织车间劳动强度、车间温度、送风方式、人员密度等实际情况,提出了确定纺织车间最小新风量的新方案,并以纺织厂细纱车间为例,计算出车间最小新风量,认为由所提方法计算出的最小新风量在保证室内空气质量的基础上能节约新风能耗。

Confirming method of minimum fresh air in air conditioning system of textile workshop was studied, Two types of existing confirming methods and emerging problems were analysed, On this basis, concept of indoor air refreshing degree was brought in, through combining practical situations including labor intensity, workshop temperature, ventilation style and labor density in textile workshop, the new way of cornfirming minimum fresh air was put out. Taking spinning workshop as example, the minimum fresh air was figured out, It is considered that the new way not only could insure air quality but also save fresh air consumption.
