Determining Preliminary System Information
For Cooling (Heat pump & Electric Strip) 250 CFM per Ton Approximately 1250-1400 Ft/min (FPM) Outlet Velocity
HE-B-50/51 HE-B-70/71 HE-B-100/101
1.5 Tons 2 Tons 2.5 Tons 3 Tons 3.5 Tons 4 Tons 5 Tons
375 CFM 500 CFM 625 CFM 750 CFM 875 CFM 1000 CFM 1250 CFM
This formula can be used to find the desired Cooling “Velocity per Outlet” needed to achieve minimum airflow or refer to chart below:
Example: Example:
A system with: A system with:
24 24 HE HE outlets and outlets and
44 2” 2” outlets outlets
will equal will equal
24 24 HE HE outlets x 2 = 48 outlets x 2 = 48
plus plus
44 2” 2” outlets = 4 outlets = 4
-------------------------- --------------------------
=52 system total outlets =52 system total outlets
250 CFM x Tonnage = Desired Cooling Airflow
Note: When finding systems total outlets, HE outlets = 2 and 2” outlets = 1
Desired Cooling Airflow ÷ Number of Systems Total Outlets = Airflow per Outlet
Airflow per Outlet ÷ 0.021 = FPM per HE Outlet
Airflow per Outlet ÷ 0.022 = FPM per 2” Outlet
Therefore,
250 CFM x ____Tons ÷ ____ Systems Total Outlets ÷ 0.021 = ________FPM per
HE
Outlet*1
250 CFM x ____Tons ÷ ____ Systems Total Outlets ÷ 0.022 = ________FPM per
2”
Outlet*2
Note: When using DX cooling maintaining minimum airflow is critical to proper system operation.
