Computational psychrometric analysis as a control problem: case of cooling and dehumidification systems

Psychrometric chart is a basic tool for analysis of processes in air-conditioning systems. While psychrometric calculators and numerical charts are widely available, there lack algorithms solving the sizing problem by using analysis. After introducing classification modelling problems direct inverse (based on relation between physical computational causality), this paper defines design as set control parameter optimization. A non-linear model obtained assembling models elementary processes. The proposes to solve method similar Newton-Raphson’s, optimization least-squares. Open-source implementation, published Zenodo repository, interactive, reproducible environment, available Binder web service, accompany (Ghiaus [2021]. PsychroAn_cool: cooling systems problem.
