If you are looking for a reliable and easy-to-use tool to size ducts for HVAC applications, you might want to try McQuay Duct Size Calculator. This software, developed by Daikin Applied, allows you to calculate the friction loss in a section of duct, or calculate the duct size for a given friction loss. You can choose from different duct types and both major unit systems. You can also input multiple sections and view the overall results. The output can be exported to Excel for further analysis.

McQuay Duct Size Calculator is available for free download from various websites, such as MEP Work[^1^], HVAC Guidelines[^3^], and EngLogs[^5^].

To use the software, you need to enter some basic information about your duct system, such as airflow rate, maximum air velocity, maximum static loss per 100 feet, duct type, and unit system. You can then choose between two methods to size your duct: equal friction method or equal velocity method. The software will calculate the duct size for you and display it in rectangular or round dimensions. You can also view the friction loss per 100 feet and per section for each duct size.

If you have more than one section in your duct system, you can add them by clicking on the "Add Section" button at the bottom of the interface. You can enter the same information as before for each section and view the results. The software will also show you the total friction loss and total length of your duct system.

If you want to export your results to Excel, you can click on the "Export" button at the top of the interface. You can choose to export all sections or only selected sections. You can also choose to export only duct sizes or all data. The software will create an Excel file with your results and save it in your chosen location.

McQuay Duct Size Calculator is a handy tool for HVAC engineers and designers who need to size ducts quickly and accurately. It is also free to use and easy to download. However, it is important to note that this software is not a substitute for professional judgment and experience. You should always verify your results with other sources and methods before finalizing your design. 29c81ba772
