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.

I am currently dealing with simulation of simple "black box" building located in humid, hot climate (Singapore). 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?
