A secondary condensate drain pan or overflow provision under a cooling coil is required primarily to:
a.Increase the cooling capacity of the coil
b.Prevent water damage if the primary condensate drain becomes blocked
c.Improve airflow across the coil
d.Reduce compressor noise
Explanation
The secondary pan or overflow catches condensate and signals or drains it if the primary line clogs, preventing overflow water from damaging ceilings and structure. It does not add cooling capacity, change airflow, or reduce compressor noise.
