Hello NH3 Group,

I have been reading posts, trying to learn a bit on a variety of subjects related to R717.
I am designing a prototype system which will utilize a NH3 Heat Pump to heat a process fluid through a plate type heat exchanger. Being a prototype, I hope to keep it small, perhaps 3-5 ton, to minimize cost.

I am located just outside of Birmingham, AL - and would like to find a technician and/or engineer having experience with NH3 - with whom I could converse / consult on some thermodynamic calculations for this system. I would be pleased to pay for your time, not looking for a freebie.

My background is industrial - mechanical systems, and while I have refrigeration experience, it is limited to R12 and R22 systems, and I am not a "refrigeration engineer."

Anyone interested, please let me know. Any recommendations for someone in my area would be greatly appreciated. I would prefer someone local, but would not rule out neighboring states.
