AC / heat-pump simulator
Set the design conditions and watch the cycle respond. Every output is computed from a real vapor-compression model — change a temperature and the physics propagates everywhere.

Pressure–enthalpy cycle
The loop sits inside the saturation dome for R-32 (difluoromethane). Compression (1→2) climbs the pressure; condensation (2→3) crosses the top; expansion (3→4) drops down; evaporation (4→1) returns along the bottom.
