[TRNSYS-users] Design of PCM tanks

[Katherine D'Avignon]

Hello Moein,

For solar I guess you would be looking into vertical hot water storage 
tanks. If so, I have heard of two models whihc might be of interest to you.

There is Type840 which can simulate a vertical tank filled with PCM 
capsules of different shapes as well as a tank filled with PCM slurry 
and a submerged heat exchanger. There is also Type842 which models a 
bulk PCM tank with an immersed water-to-air heat exchanger which was 
developed by Andreas Heinz at the Institute of Thermal Engineering in 
Graz University of Technology.

Both these models were developed as part of IEA Solar Heating and 
Cooling program task 32 but I have not yet used either of them. Enclosed 
you will find Report C5 of Subtask C which explains each model in 
detail. This document should also provide you with the names and contact 
information from each model's authors if you wish to get access to these 
models. I also recommend these papers:

Bony, J., & Citherlet, S. (2007b). Numerical model and experimental 
validation of heat storage with phase change materials. Energy and 
Buildings, 39(10), 1065-1072. doi: 10.1016/j.enbuild.2006.10.017

Bony, J., & Citherlet, S. (2007a, Sept 03-06, 2007). Comparison between 
a new TRNSYS model and experimental data of phase change in a solar 
combisystem. Paper presented at the 10th Conference of the International 
Building Performance Simulation Association Beijing, China.

I have myself produced a TRNSYS model for a PCM storage tank but it is 
for a horizontal storage tank with rectangular PCM capsules and might 
not be what you are looking for. So far, I have published only a 
conference paper on the first version of my model (see the reference 
below) but I have a paper under review which details the improved 
version of the model and its experimental validation.

D'Avignon, K., & Kummert, M. (2012). Proposed TRNSYS model for storage 
tank with encapsulated phase change materials. Paper presented at the 
5th National Conference of IBPSA-USA, Madison, Wisconsin.

If you are interested in a horizontal configuration, please let me know 
and I will get you a copy of my paper and model.

Good luck!
