Load & DesignCâu 4 / 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
Giải thích
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.
