对三台直径为36英寸（914毫米）的可变螺距轴流风机进行了噪声和性能测量，其标称轮毂直径分别为14、17和26英寸（360、430和660毫米）。三台风扇中的每一台都在四个叶片角度进行了测试，提供了十二台测试风扇。使用10个试验壁位置对12台风机进行了试验，这些试验壁位置旨在模拟在靠近进气室壁的位置安装风机的效果。本试验计划旨在满足ASHRAE研究项目1010的要求，即进气安装对叶片轴流风机的影响，空气和声音。测量是在芝加哥的国际空气运动与控制协会（AMCA）实验室进行的。 该项目的120次试验涵盖了从自由输送到接近关闭的风机流量范围，每次试验在9到11个试验点收集数据或进行测定。120次测试得出了120个风扇性能曲线、1200个风扇噪声测量值、120个参考声源（RSS）测量值和120个试验室背景（BKG）测量值。图1描述了测试风扇和测试墙的位置。在本报告中，试验风扇尺寸标识为36x14、36x17和36x26，墙壁位置标识为WP1至WP10。原始测试编码中的空间限制要求使用单个数字表示墙的位置，因此从位置10中删除–1–157;，该位置在测试数据和结果表中列为–0–157;。 注意:您需要WinZip或等效程序才能打开此文件。由于文件大，我们强烈建议下载文件时使用宽带连接（Cable/DSL/T1）。文件大小:61.3 MB（64360448字节）连接速度估计时间拨号（56K）2小时，33 MiniDN（128K）1小时，7 minDSL/电缆（768K）11 minT1（1.5M）6分钟*下载时间可能因网络流量而异。单位:双

Noise and performance measurements were made on three 36 inch (914 mm) diameter variable pitch axial fans with nominal hub diameters of 14, 17 and 26 inch (360, 430 and 660 mm). Each of the three fans was tested at four blade angles providing “twelve” test fans. The twelve fans were tested using ten test-wall positions designed to simulate the effect of installing fans in close proximity to the walls of an inlet plenum. This test program was designed to meet the requirements of ASHRAE Research Project 1010, “Inlet Installation Effects, Air and Sound, on Vaneaxial Fans.” The measurements were made at the Air Movement and Control Association International (AMCA) laboratories in Chicago.The 120 tests of this project covered the fan flow-rate range from free delivery to near shutoff with data collected at 9 to 11 test points or determinations for each test. The 120 tests yielded 120 fan performance curves, 1200 fan noise measurements, 120 Reference Sound Source (RSS) measurements and 120 test room background (BKG) measurements. Figure 1 describes the test fans and the test wall positions. The test fan sizes are identified as 36x14, 36x17 and 36x26 and the wall positions are identified as WP1 through WP10 in this report. Space limitations in the original test coding required the use of a single digit for wall position so the “1” was dropped from position 10 and that position was listed as “0” in the test data and results tables.Note: You will need WinZip or an equivalent program to open this file.
