Calculator : Absorption Refrigeration
Category   : Thermo

Files Included:
  - absorption_refrig.f90 (Fortran Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have a Fortran compiler installed (like gfortran).
Run the following compilation command in your terminal:

  gfortran -O3 absorption_refrig.f90 -o absorption_refrig

-------------------------------------------------------------------------
2. How to Execute
-------------------------------------------------------------------------
Run the compiled binary and redirect the input.txt file into stdin:

  absorption_refrig < input.txt

-------------------------------------------------------------------------
3. Input File Details
-------------------------------------------------------------------------
The input file 'input.txt' contains sequential parameters separated by
newlines. Here is the structure of the included 'input.txt':

  Line 1 (Working pair (1=NH3-H2O, 2=LiBr-H2O)): 1
  Line 2 (Generator temperature T_gen [K]): 403.15
  Line 3 (Absorber temperature T_abs [K]): 308.15
