Ashrae Duct Fitting Database 2016 [best]

Introduction

1. Expanded content: The database now includes over 300 duct fittings, with 100 new entries compared to the previous edition.
2. Improved data accuracy: The loss coefficients have been re-evaluated and updated to reflect the latest research and experimental data.
3. Enhanced search functionality: The database is searchable by fitting type, size, and other parameters, making it easier to find specific fittings.
4. SI and I-P units: The database provides loss coefficients in both SI (International System of Units) and I-P (Inch-Pound) units.

By developing this feature, engineers, designers, and contractors can easily and accurately calculate duct fitting losses, streamlining their workflow and improving the overall efficiency of their projects.

The database allows users to select specific duct components and input dimensional and airflow data to determine energy efficiency and system performance. ashrae duct fitting database 2016

Each fitting record contains:

| Group | Fitting Type | Example Fitting Numbers (2016) | |-------|--------------|--------------------------------| | CR | Round Elbows | CR3-1 (90° smooth radius), CR3-5 (mitred) | | SR | Rectangular Elbows | SR3-1 (90° smooth radius), SR5-1 (mitred with vanes) | | CT | Round Tees & Wyes | CT3-1 (90° diverging tee), CT4-1 (45° lateral) | | ST | Rectangular Tees | ST3-1 (90° converging tee), ST4-1 (45° tap) | | CD | Round Transitions | CD3-1 (concentric), CD9-1 (offset) | | SD | Rectangular Transitions | SD3-1 (pyramid), SD5-1 (offset) | | CJ | Round Junctions | CJ4-1 (multiple fittings) | | DO | Dampers | DO2-1 (opposed blade), DO3-1 (parallel blade) | Introduction

The 2016 updates were instrumental in bridging the gap between desktop and mobile. The ASHRAE Duct Fitting Database App, developed by Carmel Software, allows field engineers to perform calculations on iPhones and iPads.

To use the database effectively:

), the system immediately outputs velocity, velocity pressure, and the specific fitting loss coefficient.
