<DIV><FONT face=Arial size=2>Using TRNSYS16 for the calculation of convection
coefficients of the internal wall surfaces in a very simple building model, I
realized that I get different results when I use the "internal calculation"
facility in the wall typemanager menu and when I use Type 80. Could you please
explain to me where the difference in the two ways of calculation process
lies?</FONT></DIV>
<DIV><FONT face=Arial size=2>I would also like to know where I could find the
reference for the values of the default coefficients and exponents that are
incorporated in TRNSYS16. I</FONT><FONT face=Arial size=2>n the Manuals,
the default coefficients given in TRNSYS16 electronic user's manual (page 65)
and in Vol.6 (paper verion of the manual for Type 56) the default values seem to
be slightly different.</FONT></DIV>
