XPsych by CalculationX
Psychrometric calculator for HVAC air processes
Resolve HVAC air states, plot psychrometric chart points, model common air-treatment processes, and export reports for design review.
What XPsych calculates
XPsych helps HVAC engineers visualize air conditions, connect process steps, and document psychrometric assumptions and results.
Air state properties
Calculate dry-bulb, relative humidity, humidity ratio, enthalpy, wet-bulb, dew point, and specific volume values.
HVAC processes
Model heating, cooling, cooling and dehumidification, humidification, evaporative cooling, and heat exchanger steps.
Air mixing
Combine outdoor and return air states and review mixed air results for system design decisions.
Project documentation
Save editable projects, export .cxpsych files, and create PDF reports with chart output and project information.
