This is the closest official tool. It includes pressure drop calculations for water, glycol solutions, and refrigerants. It also contains equivalent lengths for fittings—critical when piping a McQuay chiller plant.

Users can select standard pipe materials such as Schedule 40 steel , copper, or plastic.

The (now part of the Daikin Applied design tools ) is one of the most widely used software utilities for HVAC engineers and designers. It provides a fast, accurate way to size chilled and hot water piping systems, effectively replacing manual chart calculations with a streamlined digital interface. Core Functions and Features

The McQuay Pipe Sizer is a widely used tool in the HVAC (Heating, Ventilation, and Air Conditioning) industry for sizing pipes in commercial and industrial buildings. Here's an overview:

The “McQuay pipe sizer” is less about a brand-named tool and more about applying correct hydronic principles to McQuay equipment. Use the or ASHRAE-based calculators, always stay within 4–10 fps water velocity, and match your pipe size to the chiller’s allowable pressure drop.

Note: McQuay evaporators often have 2.5" or 3" nozzles. You may need to reduce at the chiller but increase pipe diameter quickly to reduce system pressure drop.

Select 4" pipe for main runs.

Sizing a chilled water network typically involves the following steps:

McQuay Pipe Sizer is a comprehensive software tool developed by Daikin (formerly McQuay International) for sizing pipes in HVAC systems. The software is designed to simplify the pipe sizing process, reducing the risk of errors and ensuring that pipes are sized correctly for optimal system performance.
