Evodelta — refrigeration engineering, proven

Evodelta runs refrigeration and HVAC&R work on real CoolProp thermodynamics: cycle analysis, interactive P-h diagrams, pipe sizing, 20 refrigerants, cascade and transcritical CO₂. No install, no lookup tables — every number is computed from the state points you enter.

What it does

• Real CoolProp physics — COP, pressures, discharge temperature and mass flow, computed per refrigerant
• Interactive P-h diagram and 3D cycle machine — two views of the same run
• PDF and CSV export of every run, for the job file or the client
• 20 refrigerants including ammonia (R-717, GWP 0), CO₂ (R-744, GWP 1) and propane (R-290, GWP 3)
• Cascade systems, two-stage cycles, internal heat exchangers and transcritical CO₂ below -40 °C
• Pipe sizing with real pressure drops and velocity checks
