Trane Engineering Toolbox (USA)

Calculators to simplify HVAC design and service tasks

The Trane Engineering Toolbox provides nine calculation tools to simplify HVAC design and service tasks. The Engineering Toolbox provides a consolidated input and output view, an advanced report generation method for comparing multiple datasets and additional refrigerant and fluid types.

Engineering Toolbox includes the following calculation tools:

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.
