The intertwined coil configuration splits the coil sections by alternating the tubes fed in each row between two distributors.

At lower loads, liquid refrigerant is fed to every other tube of the coil and, therefore, it behaves like a coil with substantially greater fin surface. At higher loads, refrigerant is fed to all of the tubes in the coil.

Because of the increased fin surface available at part-load conditions, the coil surface does not have to be as cold to provide a constant leaving-air temperature. This reduces the potential for coil frosting. Therefore, intertwined coils are better suited for VAV applications.

Part-load humidity control is less of an issue with VAV applications due to the constant, cold leaving-air temperature. In constant-volume applications, intertwined coils provide good part-load humidity control, although potentially not as good as face-split coils.
