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.
