SAM_Mollier is part of the SAM (Sustainable Analytical Model) Toolkit —
an open-source collection of tools designed to help engineers create, manage,
and process analytical building models for energy and environmental analysis.
This repository provides psychrometric (Mollier) chart utilities used to evaluate and visualise moist air thermodynamic behaviour. It supports the creation of psychrometric points and the simulation of common air-conditioning processes such as heating, cooling, adiabatic humidification, and isothermal humidification.
A key characteristic of this module is the use of Grasshopper as a visual user interface, enabling interactive, parametric exploration of psychrometric processes and offering an intuitive workflow for both professional practice and education.
Welcome — and let’s keep the open-source journey going. 🤝
- Generation and visualisation of Mollier (psychrometric) charts
- Creation and manipulation of psychrometric state points
- Simulation of common HVAC air processes:
- heating and cooling
- adiabatic humidification
