function h = HFC134a()
% HFC134A  Return an object representing refrigerant HFC134a.
% h = HFC134a()
% The object returned by this method implements an accurate equation of
% state for refrigerant HFC134a (R134a)  that can be used in the liquid,
% vapor, saturated liquid/vapor, and supercritical regions of the phase
% diagram. Implements the equation of state given in:
