Vapor Pressure Curve Example
An
example of a typical vapor pressure curve is available here. This
curve is useful for describing the relationship of the saturation
temperatures and pressures of refrigerants.
This curve also shows the effect of changes in pressure or temperature and the resulting change in subcooling of liquid or superheating of vapor.
Be sure to see the CO2 Refrigeration page for information about the use of carbon dioxide as a refrigerant. See Industrial Refrigeration for an overview of refrigeration systems.
