[TRNSYS-users] Indoor/Outdoor Pool Type 344

[David Bradley]

Kent,
  Changing the window glazing ID to 10001 (no glazing) will allow solar 
to pass unhindered through the building envelope. I am not sure it 
captures all of the changes that you want because when your in 
indoor-pool mode, you want the pool's water mass exchange to occur 
between the pool surface and the trapped zone air. When you go to 
outdoor pool mode, however, the pool exchanges water mass with ambient 
air. I would think that at the least, you would also want to add a very 
large infiltration amount into your zone when you go into outdoor mode. 
As for the switch between indoor and outdoor mode, I took a really quick 
look at the component and it looks like if you moved some of the 
parameters to inputs, you could hot-swap the pool model in the middle of 
the simulation. If you did that, you could come up with whatever 
algorithm or forcing function you wanted to switch back and forth 
between indoor and outdoor modes.
Kind regards,
 David
