This page helps you experiment with properties and processes associated with Refrigerant 717 (Ammonia). A larger screen (say 24 inches) is recommended. Click on the plot area to inspect thermodynamic properties at different co-ordinates. You can choose between at temperature-entropy chart (Ts) and a pressure-enthalpy chart (ph). You can plot and explore processes with constant pressure, entropy and enthalpy. You can model simple refrigerators and heat pumps.
