RE: what is enthalpy?
It is the kind of energy stored by a compressible fluid.
It is the sum of the energy it had when it was just sitting there, and the energy it obtained when you did work on it.
Thus, it is the type of energy most useful to an engineer studying a system that has air, steam, water vapour, R-134a etc as the working fluid.

In HVAC/R work we are interested in enthalpy in terms of sensible and latent heat content in a given quantity of air. The common IP metric for this is btu/lb of dry air. A psychrometric chart will have enthalpy info in either this or SI form.
