In general, a large-capacity axial flow fan is used for industrial processes or ventilation in a social overhead capital infrastructure. The main characteristics of the large axial-flow fan need a lot of electrical power consumption and operate 24 hours a day, 365 days a year. Since the large axial flow fan consumes several hundreds to thousands kW per hour, both manufacturer and consumer are struggling to select high efficiency products for saving energy and reducing operation cost. Therefore, the performance testing should be accurately conducted in experimental equipments. The performance estimation and uncertainty of measurement of the axial-flow fan gathered from the result from nozzle shaped testing equipments certified with ANSI/AMCA standard and duct shaped testing equipment under the same experimental condition. The experimental results from both facilities have maximum 17% differences in performance evaluation and uncertainty of measurement. As considering that the differences, it is doubt about the reliability of testing result. The test was repeated with the specific term during 12 months because it is important to fully reflect the real conditions and to decide the repeatability of data. The evaluation of duct type testing facilities was failed to get an uncertainty measure. Testing results were previously published. As a series of previous paper, axial fan (∅1690 mm) and duct type testing facilities were fabricated. The purpose of fabricating testing equipment was testing an uncertainty measurement under the controlled environments.

문제 정의

2) show up to 17% differences with inlet chamber setup, we concluded that the calculating measurement of uncertainty conducted in inlet duct setup was infeasible.⁽¹⁾ As a series of previously published paper, the purpose of this paper is the estimation of uncertainty measurement of inlet duct setup under the controlled environments. Therefore, the air performance, flow rate variation by the changing the pitot tube angle, repeatability are compared and analyzed in this paper.

가설 설정

1) The inlet duct setup was easily affected by external environments. It is severely harmful to repeatability.
1) the high repeatability (±1.6%) which amount is lower than the AMCA.
Although the total pressure (Pt) and static pressure (Ps) are different because of of structural differences between testing facilities, it is ideal that the air flow rate is corresponding in both facilities. The data was measured in the following condition: 1) all testing facilities are fixed, 2) all sensors are fixed, 3) the rpm of axial flow fan was fixed and 4) the degree of pitot tube axis was fixed parallel to the axis of the duct.
In the whole test, we assumed that the air flow rate obtained from inlet duct set is under allowable tolerance level from AMCA standard. The uncertainty measurement of measured air flow rate was estimated based on AMCA 201-07.

제안 방법

In this test, the air flow was measured in two different testing facilities, inlet chamber and inlet duct. The inlet chamber setup was intended for the standard air flow meter.
The purpose of testing is comparing the air flow rate measured from inlet duct setup and nozzle chamber setup as standard. The ideal case is the air flow rate is corresponding in both facilities.
The reasons are the cost of inlet chamber setup is tremendously expensive and the number of inlet chamber applicable to large axial fan is limited. The purpose of this paper is comparing and analyzing the air performance of large axial fan at the Inlet chamber setup and inlet duct setup.
The test was repeated with the specific term during 12 months because it is important to fully reflect the real conditions and to decide the repeatability of data. During the test, the large axial fan was tested in the AMCA accredited Inlet chamber and Inlet duct setup installed outside of building.
⁽¹⁾ As a series of previously published paper, the purpose of this paper is the estimation of uncertainty measurement of inlet duct setup under the controlled environments. Therefore, the air performance, flow rate variation by the changing the pitot tube angle, repeatability are compared and analyzed in this paper. The test results are analyzed based on ANSI/AMCA 210-07, Annex F.

The test was repeated with the specific term during 12 months because it is important to fully reflect the real conditions and to decide the repeatability of data. During the test, the large axial fan was tested in the AMCA accredited Inlet chamber and Inlet duct setup installed outside of building. The inlet chamber setup showed(Fig.
The detailed specification of testing facilities is on the following table 1. The testing facilities are multi nozzle chamber (Fig. 3a) as a standard equipment, inlet duct setup (Fig. 3b) equipped with pitot tube array for the purpose of comparing air flow rate, and axial flow fan as a test object. The detailed installation of testing facilities is in the following Fig.

2) Although the testing was conducted in the controlled environments, the result using suction duct is hard to get reliability and repeatability.
