Visualizing HVAC Excellence Ep. 8: Pressure-Enthalpy — Reading Between the Lines, No Tears Required

What happens when pressure, heat content, state changes, and the refrigeration cycle all come together on one diagram? In Episode 8 of Visualizing HVAC Excellence, we break down Pressure-Enthalpy — Reading Between the Lines, No Tears Required — and explore how the P-H diagram helps students, instructors, and technicians better understand HVACR system operation. Featuring Professor Eugene Silberstein, CMHE, National Programs Director at HVAC Excellence, this episode focuses on pressure-enthalpy diagrams, refrigerant state changes, heat content, compression, condensation, expansion, evaporation, superheat, subcooling, and how the refrigeration cycle can be visualized on one chart. Using interactive 3D HVAC training visuals from Visual 3D Academy, we help make the pressure-enthalpy diagram easier to see, understand, teach, diagnose, and apply. See it. Learn it. Apply it.
