Compressor Sizing

Can't be done. Even if you gave us some idea of the type of compresser, size of compresser and motor information, which you do not.

How can you possibly expect an answer to such an impossibly incomplete question????

If it looks big, it might be alot.

I think the rule of thumb is 1,000 Btu per foot of circumference/the power cord length in inches.

The rule of thumb is for every horsepower on the motor you get 4 CFM from the compressor. This is the rule of thumb for reciprocating compressors. eg.. 5 HP = 20 cfm good luck!

First of all-- what is this compressor doing--is it air compressor, air conditioning compressor 0r ?. Is it open, hermetically sealed or ?

If a motor is attached to it and its HP is known--we can get cfm delivered by it-when it is air cond. compressor. when Motor is small, fractional or close and it is hermetically sealed it is an air cond. or refrigeration compressor. Air compressors are not hermetically sealed.

There are so many IF's. We must know the purpose this compressor is there for. Is it connected to ductwork to deliver air to a space or for ?? dompressed air to a process etc.

Good luck. Please share this small research to help us find out.

If you are using the compressor as part of a refrigeration system the rule of thumb depends on the cold temperature. ASHRAE "suggests" 0.87 to 3.25 HP/ton cooling. Capacity will vary significantly based on condensing temperature, and desired evaporator temperature.

Give us more information and some one can develope a better answer. Is this for cooling, compressed gas, or what? What are temperatures? What is the working fluid? What is the compressor pressure rise?
