笛利文特(Direvent,意即定向通风——整理者注)是1974年瑞典SF公司研究成的一种在大空间中有效地分配空气的新方法,它利用从喷嘴吹出的高速气流的动量,把新风分送到整个室内达到通风换气的目的。据介绍在欧州已有近200个工程采用了这种系统,解决了过去大空间通风中未能解决的一些难题(例如送风量大,风管大、占用空间大等)。一、系统的概要笛利文特系统是由小容量的送风机A, Direvent (Directional Ventilation - Sorter’s Note) was a new method developed by Swedish SF company to effectively distribute air in a large space. It uses the momentum of the high-speed airflow blown from the nozzle. The fresh air is distributed to the entire room for the purpose of ventilation and ventilation. It has been reported that nearly 200 projects in Europe have adopted such a system, which has solved some of the problems that had not been solved in large space ventilation in the past (such as large air supply volume, large air ducts, and large occupied space). First, the system’s overview The DLV system is a small capacity blower A,
