[esp-r] Re: implementing different PCM models

[Juanita Solano Guzmán]

-- in addition to my previous email. This is how my SPMCMP53 model looks
like in the .spm file:

# ESP-r special materials file used in
# configuration file Sonnenschiff.cfg
   6  # Number of special material nodes.
# Node No:  1
PCM_Cap          # label
# Zone Surf Node Type Opq/Trn
   1   1   2  53   1
# Number of data items.
   7
# Data:
   24.00000   26.0000    0.2000    0.2000 1730.4200    0.0000    17589.5

Melting range = 24 - 26°C
Thermal conductivity in both liquid and solid phases = 0,20 W/m.K
Specific heat in all phases = 1730.42 J/kg.°C
Latent heat coefficient "a" = 0
Latent heat coefficient "b" = 17589,5 J/kg.°C = Total latent heat / Melting
range difference. Here my total latent heat = 35179 J/kg and my melting
range difference = 2 °C
