Why are you providing wetbulb and dewpoint? Can you provide the absolute humidity instead? I'll try to fix this bug, but I don't know how involved it will be, and I'm short on time right now.

Hello Ian, I tried to use absolute humidity instead of dew point, but problem is the same ( see #399)

I was thinking get rid of wetbulb, since that is the most problematic from
a numerical standpoint.

Adsorption as a modification of air follows an Iso-wetbulb .... I think it's a good thing to maintain wetbulb ....

Sorry I don't know what I was thinking with that comment, maybe I meant
providing wetbulb and dewpoint, but yes, wetbulb will definitely still be
supported.

hello Ian,
I tried the last version of coolprop:
HapropsSi(Output, W, Value_W, Input2, Value2, P, 101325) don't work for Input2 = B, H, R, V.

Please provide a separate issue, and please give the numerical values that
don't work.
