10.2. Condenser model
The condenser was modelled by dividing into zones corresponding
to the refrigerant state (superheated, two-phase, subcooled).
The condenser consisted of 46 individual tubes (Ntubes) and
6 tube passes (Npasses).
The ε-NTU method is used to evaluate the heat exchanger
performance. The conductance, UA, for each zone is determined by
