Digitale Tools Und Ressourcen
Ductulator and Pressure Loss (friction) calculator
Streamline your HVAC design process with our comprehensive digital Ductulator and Pressure Loss Calculator. This all-in-one tool allows you to instantly convert duct shapes, determine optimal sizing based on friction or velocity constraints, and accurately calculate total pressure loss and airflow rates for complex ductwork systems.
Air mixing calculator
Accurately determine the final thermodynamic state of combined airstreams. Input flow rates and air properties to instantly calculate mixed air conditions, streamlining AHU fresh-air and return-air mixing design.
Psychrometric state calculator
Instantly determine the complete psychrometric state of moist air using just two inputs. Enter dry-bulb temperature alongside any single humidity parameter to automatically calculate dew point, wet-bulb, relative humidity, enthalpy, specific volume, and density for precise HVAC design and analysis.
Expansion Tank Sizing Calculator
Size bladder, diaphragm, or plain-steel expansion tanks for closed hydronic systems in seconds. This calculator applies thermal-expansion and pressure-ratio principles from Steven T. Taylor’s ASHRAE-referenced sizing method and the ASME Boiler and Pressure Vessel Code, Section VI, to compute the minimum required tank acceptance volume for hot water, chilled water, and mixed-temperature systems. Supports US and SI units, all four major tank styles, an optional piping-expansion credit, and a built-in ASME/UMC/IMC cross-check for 170–230°F systems — with clear pass/warning/invalid status and next-step guidance for tank selection and precharge verification.
Critical Radius of Insulation Calculator
Determines the critical radius (and critical thickness) of insulation for a cylinder or sphere — the outer radius at which heat loss is maximum — and compares heat‑loss rates before and after insulation.
