Cooling Air Fluids/Thermo Help
I am looking to cool my air supply before applying it to an application in a temperature chamber. The chamber will be at -40°F the air supply from outside the chamber will be ambient temperature. I want my supply air to be cooled to the -40°F before it enters my application. I was thinking simply routing the air through coiled copper would do the trick in the chamber but I was hoping to have some assurance via equations( length and size of tube needed to ensure all heat has been removed) I am thinking this should be simple but I keep finding stuff in books over complicating the process(I think)
Please Help.
