Have you considered using one of the
TESS cooling coils? The Bypass Fraction Method coils (TESS/HVAC/Cooling
Coils, Type 508) have modes for outlet humidity and temperature control.
Also, the Performance Map cooling coil (Type 697) allows you to specify
both total and sensible cooling capacity.

[TRNSYS-users] Simulating a cooling coil with sensible
load only
Hello, Trnsys users.
I am designing a hybrid solar-cooling system and I want to select a cooling coil to handle the sensible load only (see attached file). I use the Type52b
for the cooling coil. However, I find that I can't achieve a sensible-cooling-only condition, even though the outlet air temperature is substantially higher
than the inlet air dewpoint. The resulting coil capacity becomes much
higher than what I expect. Does the model for Type52b prohibit a sensible-cooling-only case? If so, is there any other compoent types for the cooling coil
which can fulfil my requirement? Your reply is highly appreciated. Thank
you!
