Trane Engineering Toolbox

Engineering Toolbox provides nine calculation tools to simplify HVAC design and service tasks. The latest version 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.

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.
