Everything about the product and the calculations in one place.
PsychroView is an online tool for psychrometric calculations and drawing the Mollier (h-x) diagram, built for HVAC/building-services designers, energy specialists and students. It replaces manual chart reading or spreadsheet calculations.
The diagram supports zoom, pan, custom axis range and step, relative-humidity and enthalpy isolines, and a dark/light theme. Points can be dragged directly with the mouse and values recalculate in real time.
Heating, cooling (with and without dehumidification), humidification (steam and adiabatic), heat recovery (plate and rotary exchangers), mixing and stream splitting. Processes can be chained into a cascade to track the air state step by step.
Calculations follow ASHRAE Fundamentals 2021, Chapter 1 (SI), Hyland-Wexler equations. Maximum deviation of saturation pressure from reference data is 0.041 %.
Yes. The app includes a database of climate stations (Czechia, Slovakia, Austria, Germany) with design percentiles, or you can upload your own climate data in JSON/CSV format and use it as a calculation input.
The Builder is an alternative graphical interface on top of the calculation engine — you assemble an air-handling unit from functional and passive parts (filter, fan, silencer) and define multiple operating modes (summer/winter) for one assembly.
Autopilot is an assistant that, based on the input and target conditions you specify, suggests a suitable process cascade (e.g. the required cooling and reheat capacity) instead of building each step manually.
The diagram and results table can be exported as vector PDF for project documentation, DXF for AutoCAD, and PNG at any resolution.
Yes, you can generate a read-only link and share a project without the other side needing to create an account.
Yes, the embed widget is free and unrestricted on any website. It supports both light and dark mode and is fully responsive.
Yes, the interface is responsive and works in a mobile browser. For larger process cascades a bigger screen is recommended.
Yes, the application is accessible with limitations without registration. After registration, it includes a basic diagram with a limited number of processes.
Yes, cancellation is done in the account settings.
The trial period runs in early access mode, when the application is being tested. Users will be notified of its termination
The projects will be permanently deleted.
