Summary

A model has been developed and tested by comparison with experimental data from the literature. The heat transfer rates were predicted to within 5% of the experimental value for seven corrugated-fin coils representing a wide range of geometries. Air-side pressure drop predictions were less accurate. The model was able to predict the air-side pressure drop within 25% for three of four coils whose geometrical parameters were within the range of applicability of the model. A coil circuiting can affect the heat transfer performance by as much as 90%. Water-side turbulence promoters were effective in improving the performance of coils that operate on low water velocities. For a given fin surface area, coils with more tube rows tend to perform better than do coils with greater fin densities.
