本文讨论了单风机与联合风机的基本理论,阐明了某些风机适合并联或串联的缘由。文中还涉及风筒性能的基本原理及其应用并有效地解决了一些通风问题。详细论述特定通风条件下风机最佳联合的计算方法,包括通风性能改良途径的评议。对基本通风方式,并联系排放(有毒有害)气体措施作了简要介绍。对交替备用的通风系统装置结合风机维修一并予以说明。
This paper discusses the basic theory of single-fan and combined fan, illustrates the reason why some fans are suitable for parallel or series connection. The article also covers the basic principles of duct performance and its application and effectively solve some of the ventilation problems. This paper discusses in detail the calculation method of the best combination of fans under specific ventilation conditions, including the assessment of ways to improve the ventilation performance. Briefing on the basic ventilation methods and the measures for the emission (toxic and harmful) gases. Alternate alternate ventilation system with blower maintenance will be described.
