[TRNSYS-users] Type1 Number of identical collectors in series has no effect

[David BRADLEY via TRNSYS-users]

Antoine,

   I'm not 100% sure that I follow your logic but you can model that 
array with a single instance of Type1. If your single module has an area 
of 1m2 and wants a flow rate of 400kg/h then the full array of 50 
modules (10 in parallel, 5 in series) would have:

area = 50 m2

number in series = 5

flow rate = 4000kg/h (400kg/h x 10 in parallel)

best,

  David
