Re: [TRNSYS-users] PCM type

[David Bradley <bradley@tess-inc.com>]

Dear Prof. Nyak,
  We wrote a model of a photovoltaic (PV) array that had a PCM layer 
built into it. Our approach in modeling it was to write an energy 
balance on the layer and to keep track of how much latent energy of 
melting/solidification had been "used up" based on the net energy 
flow into or out of the layer. We asked the user to supply the 
specific heat of the liquid PCM material and the specific heat of the 
solid PCM material and we linearly interpolated between the two to 
find the specific heat of the layer when it was partially solid and 
partially melted. I have heard of some PCM thermal storage tank 
models but I do not have any specific experience with them.
Cheers,
 David
