[TRNSYS-users] Capacitance clarification in TYPE536

[David BRADLEY]

Dev,
   The capacitance should account for the thermal capacitance of the 
entire array (collectors, manifolds, fluid etc.). A single differential 
equation governs the array; there are not separate but coupled 
differential equations for the fluid and for the array itself. Since we 
do not have a second differential equation, we distribute the 
capacitance of the entire array into the number of collector nodes.
Kind regards,
  David
