Listen, I really came here to gain some VERY basic knowledge, not create a fit but being referred to as an amateur gives me a giggle. What I think is funny is doctors, attorneys, engineers share revelations and knowledge but the "HVAC rocket science" MUST be way over my head. I realize that by one post, it is hard to sum someone up but I assure you, as a patent holder of 3 innovative engineering patents, developer of composite aero structures, harmonic fatigue specialist, etc, I assure you, HVAC or more decisively, heat loss and thermodynamic calculations are not "above my head".
I find it rather snooty to tout this whole "we are the "pros", you are but a peon. Especially when you find all over the net that most installers pretty much just ball park their heat loss calcs and install systems upwards of 200% too big. But THEY are the pros.....
I think my questions sound rather primitive but what you fail to realize is it is really not the fundamentals that are missing, it is the time table to build calcs for this terribly turbulent insulated piping. Where do you get your data?? I will guess the "engineering" teams of the OEM. And that is now where I am going because I know they will have dynamic flow charts for their products and will get me what I need.
I have no idea in the world what pressure these systems run at but you know, it really is NOT rocket science here so just another call to an OE engineer and we will have that too. My guess is .5-1.5in H2O, but that is merely a guess.
Usually when I get the line of BS of "pros" it seems to surround a bunch of folks that have to hide their rather simple mechanics of their profession. You don't see doctors shielding info on innovative heart surgeries do you???
OK, I am done. please remove. Just remember, next time you want to fix your car and your mechanic says "I cannot give you any timing specs because you will then know how to fix your own car", you just think of your own septic pool.....
