Load & DesignQuestion 4 of 110
A 4-ton air-conditioning system is designed at 400 CFM per ton. What total supply airflow is required?
a.800 CFM
b.1,200 CFM
c.1,600 CFM
d.2,000 CFM
Explanation
Multiply tons by CFM per ton: 4 tons x 400 CFM = 1,600 CFM. Sizing the blower and ductwork for this airflow ensures the coil receives adequate air for rated capacity. Undersized ducts would restrict this airflow and reduce performance.
