Modify an air engine to run refrigerant 2

[tom3x]

I am new to this site. I hope I am posting this question in the proper forum. I plan to run a refrigerant through an off-the-shelf vane type air motor. These motors can handle 80 psi. So, I'm going to use co-generation to heat a low pressure refrigerant to 150 degrees Fahrenheit, to get that 80 psi vapor pressure for the engine. The air motor uses 10 scfm to produce X torgue at X rpm. If I provide 10 cubic feet of refrigerant at the condenser pressure, to the motor, will the motor produce the same torque that it would using air? Or, as I suspect, if it is much more complicated, how do I calculate the amount of refrigerant necessary to duplicate power from air.

Welcome tom,

I don't have anything relevant to your question at the moment but I just wanted to let you know that this topic in particular is not that active. I would try posting this question in one of the 'Mechanical Engineers' sections, they have more traffic.

Good luck!
