Hi I have to study the behavior of a building with PCM and I was looking for some types. I only found TYPE 204 and as I read, it´s really difficult to understand how it works. Thus it has 4 external files and I don´t understand them, I don´t know the meaning of "tile" for example and the simulation takes long time.... Actually I´m really lost and I´m not able to get a good simulation. What about the TYPE 241 ?? If someone could help me or give any idea I´d be very very very grateful. I wanted to discover a new pcm type or a simple explanation about type 204 because I´m very confused. Thanks in advance!!
