ThermoCycle Lab
See the cycle change.
Move one control and watch pressure, energy, and COP respond. ThermoCycle Lab is an offline visual notebook for refrigeration and heat-pump intuition.
Offline learning tool
Understand the four-state loop.
ThermoCycle Lab keeps the first experience focused: one ideal vapor-compression cycle, clear assumptions, and a tactile relationship between a parameter and a diagram.
P-h and T-s views
Follow the same four state points on pressure–enthalpy and temperature–entropy diagrams.
Guided experiments
Raise the heat sink, add superheat, or swap a teaching preset and see what moves.
Transparent exports
Share CSV or JSON with units, assumptions, valid ranges, and all state-point values.
Scope
Built for intuition, not equipment decisions.
The bundled values are rounded teaching coefficients. The app is not professional HVAC sizing, refrigerant charging, safety advice, equipment selection, or engineering certification.
