Load & Design第 21 / 110 题
A 3-ton system is selected for a home. At 400 CFM per ton, what is the target blower airflow?
a.800 CFM
b.1,000 CFM
c.1,200 CFM
d.1,500 CFM
解析
3 tons x 400 CFM per ton = 1,200 CFM. The blower and duct system should be configured to deliver this airflow at the system's external static pressure. Verifying actual airflow after installation confirms proper capacity.
