摘　　要：在大车间自然通风设计中,自然通风器的性能尤为重要,其主要参数为局部阻力系数,这一参数直接影响通风效果。而现阶段市场上的通风器质量差异较大,通风器阻力系数测试困难,严重影响使用效果。通过试验,对通风器阻力系数进行测定,提出了一套行之有效的阻力系数测试方法,为准确评价自然通风器的性能提供了可靠的依据。The performance of natural ventilator is very importantin the design of natural ventilation of the large workshops.Its main parameter is local re sistance cofficient,which diretly affects the ventilation ffect.At present,the quality of ventilators in the market varies significantly,and it is diffcult to test the resistance coefficient of ventilators,which seriously alects the use effect.Through the experiment,the resistance cofficient of the ventilator is measured,and a set of effective resistance coffcient test method is put forward,which provides a reliable basis for the accurate evaluation of the perform-ance of the natural ventilator.
