Ashrae Duct Fitting Database Version 60005 Official

Intuitive Search and Filtering: Users can quickly locate fittings by inputting specific parameters such as aspect ratios, flow rates, and velocity. The software dynamically calculates the loss coefficient based on the user's specific inputs, providing instant results that can be exported directly into design reports.

of the pressure loss between common sheet metal and flexible duct fittings?

A key technical specification is that version 6.00.05 is exclusively a , and network or multi-user licenses are not available. The software is designed for Microsoft Windows systems with 32-bit architecture and has been tested for compatibility from Windows XP through to Windows 11. ashrae duct fitting database version 60005

Added round straight ducts for constant equal friction (CD11-4) and velocity-limited designs (CD11-3), as well as flexible elbows with specific r/D ratios (CD3-22, CD3-23).

Contains the master catalog of 2,100+ fittings, each with a unique 5-digit ID (e.g., T020 for a diverging 45-degree wye). Intuitive Search and Filtering: Users can quickly locate

The , specifically the modern cloud-based version which replaces older versions like 6.00.05 , is an essential tool for mechanical engineers used to calculate pressure losses in HVAC systems. It provides access to loss coefficient tables for over 200 different round, rectangular, and flat oval duct fittings. Key Features and Capabilities

For the uninitiated: the DFDB is the digital home of experimentally derived loss coefficients (C₀, C₁, C₂) for thousands of duct fittings. Instead of guessing, you look up a fitting shape, input geometry, and get dynamic loss coefficients. It powers software like , Elite HVAC , and many in-house tools. A key technical specification is that version 6

A layman might ask: "Why does the database care if the radius of the bend is 1.5 times the diameter or 2.0 times?"

Properly sizing fans, air handling units (AHUs), and fan coil units (FCUs) based on External Static Pressure (ESP).

Using the correct, up-to-date loss coefficients isn't just about efficiency; it's about contractual accuracy. If you are specifying fan static pressure, using an outdated database (pre-60005) might under-spec your fan by 5-10%.

A key aspect of version 6.00.05 is its cloud-based access model. Purchasers receive a to the web-hosted version of the database. This transition moves away from the physical CD-ROMs of the past toward a modern, always-accessible service. However, it's crucial to note that this version is designated as a single-user product, and multiple-user licensing is not available. In addition to the full version, ASHRAE also offers a free ASHRAE Duct Fitting Database Lite app on the Apple App Store, which allows users to perform pressure loss calculations for a subset of the 240+ ASHRAE fittings for quick, on-the-go estimates.
