THE RESEARCH OF TYPICAL VENTILATION METHODS OF AIR CONDITIONING IN TEXTILE MILLS: PART II – EXPERIMENTAL AND CFD STUDY ON AIRFLOW DISTRIBUTION IN WORKPLACE
This is the second one in a series of two articles with the goal of evaluating and comparing the performance of typical ventilation methods in current textile mills. This paper is aimed at experimental and CFD analysis of airflow distribution in the textile mills. The airflow performance of three exhaust methods, DTEM and CSRAM and DBEM, were compared by tracing the contour of airflow distribution in vertical and horizontal directions. Furthermore, CFD study on airflow distribution was also conducted for the same three exhaust methods in the textile workplace. When DTEM was used, the zone in 4m level upward from the spinning-frame had the optimal performance of airflow pattern. However, the optimal performance of airflow pattern for CSRAM and DBEM appeared in the zone of 2m level leand 1.5m level upward from the spinningframe, respectively. The results of CFD analysis can also show that DBEM performed best among the three ventilation methods because the most of supply air reached the occupied zone of textile workplace.
