本文比较了三种不同类型的变风量风机的性能特点。它们是翼型离心式、前弯离心式和可调叶片轴向螺距。本文介绍了翼型和轴向设计在气流减少时的声音和马力特性的最新测试数据。前弯风扇未经测试，但包括了TC 6.2成员比尔·奥斯特兰德提交的性能数据。引文:研讨会，ASHRAE交易，第80卷，第一部分，加利福尼亚州洛杉矶

Compared in this paper are the performance characteristics of the three different types of fansavailable for Variable Air Volume Systems. They are the airfoil centrifugal, forward curvedcentrifugal and adjustable pitch vaneaxial. Presented are recent test data of sound and horsepowercharacteristics, at reduced airflow, for the airfoil and axial designs. The forward curved fan wasnot tested but performance data which were submitted by Bill Ostrander, a member of TC 6.2 areincluded.
