Finally, the row-splitcoil configuration, also called vertical-split or series-flow, places the independently-controlled coil sections in series in the airstream. All of the air passes through both coil sections, one before the other.

Typically, the first few upstream rows of the coil are served by one distributor, and the remaining downstream rows by another distributor. At lower loads, only the downstream section is active. At higher loads, the full depth of the coil is active.

Row-split coils are very difficult to split into equal-capacity sections. Since the air entering the downstream section of coil has already been cooled somewhat by the upstream section of coil, the air-to-refrigerant temperature difference is much smaller. Therefore, the downstream section of coil requires more rows of tubes to deliver about the same capacity as the upstream section of coil. A common row-split arrangement uses two rows for the upstream section and
