Unobstructed flow of condenser air is essential to maintain chiller capacity and oper-
ating efficiency. When determining unit placement, give careful consideration to
assuring a sufficient flow of air across the condenser heat transfer surface. Two detri-
mental conditions are possible and must be avoided if optimum performance is to be
achieved: warm air recirculation and coil starvation.

Warm air recirculation occurs when discharge air from the condenser fans is recycled
back to the condenser coil inlet. Coil starvation occurs when free airflow to (or from)
the condenser is restricted.

Both warm air recirculation and coil starvation cause reduction in unit efficiency and
capacity due to the increased head pressures.
