Engineering Toolbox provides nine calculation tools to simplify HVAC
design and service tasks. The latest version of the Engineering
Toolbox is an intuitive redesign that provides a consolidated input
and output view, an advanced report generation method for comparing
multiple datasets and additional refrigerant and fluid types
Beginning in 2023, new extended renewal subscription options will be available for the TRACE 700 family of products and Trane Design Tools. Learn more about your software End of Service and Support options.
Nine Calculation Tools to Simplify HVAC and Design and Service Tasks:
Power Factor Correction
Helps determine the required amount of capacitance for power factor correction.
Refrigerant Line Sizing
Allows selection of sizes of the interconnecting piping in a refrigerant system including suction line, discharge line and liquid line for a given system.
Properties of Air
Calculates all properties of moist or dry air at normal HVAC conditions using one state point.
Mixed Air Properties
Calculates all properties of moist or dry air at normal HVAC conditions using two state points.
Fluid Properties
Calculates physical properties for eight common HVAC fluids.
Ductulator®
This electronic version simplifies the manual process of sizing ductwork based on Friction Losses by Darcy and Colebrook Equation.
Refrigerant Properties
Calculates physical properties for several common HVAC refrigerants.
Fan Law Calculator
Calculates adjusted fan properties by applying either the 1st or 4th fan law on a set of initial and adjusted conditions.
Unit Converter
Facilitates quick, accurate conversion between almost every possible HVAC unit of measure from one system to another.
