[TRNSYS-users] Simple simulation

[David BRADLEY]

Marek,
   The connection from your weather component (Type15) to your 
psychrometrics component (Type33) includes the humidity ratio but no 
atmospheric pressure or temperature. Consequently, Type33 is trying to 
calculate thermodynamic moist air properties for a varying humidity 
ratio at a constant 20C and 1atm. Very often the result that it comes up 
with is above the saturation line. I think if you connect the ambient 
temperature and pressure to Type33 your errors will go away.
Regards,
  David

I downloaed the data from Energy + site and result of simulation should be condensation in the building....I have problem with running the simulation, it causes errors all the time. Can you help?
