Help with Convection/Cooling System

[KmOaZn]

I am looking to send compressed air into a temperature chamber which will be cooler than ambient . The air is to be utilized inside the chamber but before it is I want to make sure it has dropped to the temperature of the chamber so pressure readings won't be skewed.

I am envisioning some sort of copper tube system that the air will flow through in the chamber (already cooled) before it is used, I need help figuring out the length and size of tube that would be required to ensure my temp drop is reached.

I was thinking it would be along the line of Q=hA(Tw-Tt) This won't help me figure out the tubing required though because I don't know Q ahead of time or do I?

The best way to determine the size and length of the tubing required for your application is to consult a thermal engineer or HVAC specialist. They will be able to use the temperature difference between the ambient air and the temperature chamber, as well as the pressure of the compressed air, to determine the size and length of copper tubing that should be used. Additionally, they may be able to provide you with a system design that could be implemented to optimize your desired temperature drop.
