A Word About Our Name
In Psychrometrics, the study of the properties of air, the term enthalpy
represents the total amount of heat in a given quantity of air. Most
air conditioning processes involve a change in enthalpy.
In scientific notation the symbol for change is the Greek letter . The
standard symbol for enthalpy is h. A change in enthalpy is therefore h,
pronounced Delta h.
Our success depends upon there being a significant need for h.
