Ahu Cfm Calculation
2016-12-12 14:39:06 · answer #2 · answered by ? 4 · 0⤊ 0⤋
Are you trying to determine the size of a new AHU or are you trying to determine the capacity of an existing AHU?
Sizing a new AHU will require more information on what the AHU will be serving. What type of a space is being conditioned? Where it is located? What is the space constructed of? How large is the space you are trying to condition?
If this is an existing AHU, see if you can get the nameplate data from the unit. Some nameplates will indicate the airflow. If nothing else the nameplate will have a model and serial numbers. With these numbers the local equipment representative may be able to trace what the unit was designed for.
Also, for an existing system. You can take an airflow reading in the unit's supply ductwork. You will need special equipment or hire an air balancer to take the readings.

If you divide total volume of gas moved by the compressor with tons capacity of the compressor then the result will be CFM/TON. By the way CFM means cubic feet per minute and it is used for air quantity delivered to the area by a unit, approximately 400 CFM per Ton is a standard figure.

Not possible without a lot more information. tonage is the weight of something in tons. CFM, cubic feet per minute, is a flow rate. .

Measure the air velocity and the area of the pipe or vent through which the air is pumped out. Area x velocity is the volume. Multiply by 60 to get cfm.
